1973 240Z KA24DET

Post by Aaj2k5 » Wed Apr 06, 2011 5:05 am

This is in my opinion a fairly huge build, and seeing as I am a full time Mechanical Engineering student at Conestoga and work part time at RONA, there is no set deadline on this build (low budget per pay etc, working on it one day a week.), but in the end it will be minty fresh :cool:

Soo, this build started as an 1990 SOHC 240SX hatch, KA24Power's old car. Probably should not have sold this car, but I wouldnt have an S30 if i didn't lol.

Image

I sold that to Kollo (who is building it now), and bought a black 1995 Zenki 240 off Simplemind7.

Image

The S14 was f*cked. It looked fairly clean underneath - but that turned out to be massive amounts of bondo, fiberglass, hot glue gun sticks, drywall mesh tape, cardboard, hockey tape and duck tape used to fix anything wrong with it :/: The floor was soggy. I've never seen anything like it. The floor was solid at the frame rail joint, but the floor folded down around the frame at least an inch at the greatest movement. Wasn't rusted out or anything, just... soggy. (NOTE: I am in no way blaming Brendan for doing these things to it - I know thats not his style - whoever did do this however deserves a punch in the ovaries). Fenders and front bumper were held on with self tapping zinc plated screws..

Image
Image

My entire direction for this build changed in the past 3 days. Friday night an idea came upon me, and I researched. Saturday night I went and took a look at a disassembled car and put a deposit down. Sunday night, much thanks to a few guys helping me out huge (David, Ben and John), I picked up said disassembled car and brought it to my shop. I picked up an entire 1973 240Z, in parts, for a extremely good price.

Image
Image
Image
Image
Image
Image
Image

Don't mind the surface rust on the frame rail - they're 100x more solid than any S13 rail I've seen lol.

Looks half decent with some Blitz Type 03's..

Image
Image
Image

Spent some money on these that probably shouldve been spent on the Datsun lol. Oh well. Green XJ daily - then S13 daily - now red WJ daily - need new pics with lift and other mods.

Image
Image
Image

Due to various reasons, left my shop in Tavistock (~2000 sqft) and crammed everything into my garage (~200 sq ft) FML. Space is a little tight. Working @ Rona part time has its benefits i.e. 1.25" thick melamine workbench for ~$5. I'll miss the shop mascot though.

Image
Image
Image
Image

Figured it was time for a legit rotisserie -

Image

Stripped all paint off the car, as well as up to 3/8" thick of bondo off the roof and rear quarters even though the metal on the roof was perfect, and it looked as though they tried to reshape the contours of the rear for no particular reason. Used stripper, sandblaster as well as blowtorch and scraper. Primered it, and will get little spot touch ups when time comes for paint.

Image
Image
Image

I'm set for fuel, cams, efan, fidanza,

Image
Image
Image
Image

5 bolt had to be removed from R34 GTR knuckle so I can use the Z32 big spline 5 lug. It appears as though the GTR knuckle is an aluminum version of the S14 which would eliminate the issue of coilovers for you guys that upgrade to Z32 uprights and need to switch bottom mounts.

Step 1: 3 Jackstands and a BFH.
Image

Step 2: Booya.
Image

Z32 Big Spline 5 Lug, S14 Front spindles, FLCA. Bushing on the FLCA had to be ground down 1/16" to fit the S30 Subframe..

Image
Image
Image

Garrett GT3076R 0.60 A/R - Super Legit Paperweight.

Image

Z33 VQ35 6 Speed :D Vs. KA

Image
Image

A little bit of the dirty work. The name of the paint stripper is true.. As are the warning symbols :| Second pic shows one coat of stripper left on for 10 minutes which was wiped off and then a coat of easy off to degrease. Works wonders.

Image
Image

Started cleaning up / primering parts while my money is tied up in school. That way when I buy all the remaining parts I can assemble **** without waiting around on cleaning em :D Also, started to measure & design my build in Solidworks. Have the 5 lug, Q45 output shafts, Brake rotors, as well as starting on engine. For dreaming purposes the KA crank is fully balanced, but i'll be changing it to realism someday..

Image
Image
Image
Image

Picked up a new cowl piece - thx JP.

Image

This probably shouldn't have been used as a amp ground wire..

Image

A buddy hooked me up with a E36 M3 Dash, centre console, glovebox, trim etc.. Will need a tiny bit of trimming obviously, but is almost the same curve and width as S30. E46 M3 Cluster looks alot nicer, so i'll probably end up going for it.

Started hacking the E36 dash with a dremel + sawblade.

Image

Image

Image

Thinking about taking off these drip trays - i think it'll look hell of a lot better.. thoughts?

If someone wants a FG S30 replica to start off of you can have it for a doubledouble :D.
Image

The black 240z has a roughly similar end product as what I want, however mine will be a fair bit wider. Talks with Weirtech about a cage for the Z similar to this, but with adjusments to meet spec here:

Image
Image
Image

Good news is that I bought a ZEDD Findings floor kit which is perfect as I am lifting the floors 1 3/4" to 2", as they sit below the rockers, and would scrape like nobody's business. I need to fab up my own GTR subframe mount and will probably make my own floor rails as the ZEDD findings ones are just bent 18ga sheet. After major components are fabbed up, I will take the car on rotisserie to nearest Line-X and spray the entire bottom - stiffens the hell out of it, sound deadens, as well as the obvious rust proofing bonus..

My new friend.

Image

After grinding:

Image

After primer;

Image

Cleaned up and painted the Z32 5 lug and BNR34 knuckles.

Image

Also kept busy lifting my daily - this is beside a stocker. 3" IRO lift which lifted it 4.375" all around before sag and is at about 4.25" after 2 weeks.

Image

Here's some more-

Beforish:

Image

After a couple hours:

Image

Image

Started cutting off all those annoying clip things.

Image

Bought one of these: Q45 90mm throttle body + tps.

Image

I should probably apologize somewhere in the thread for taking all pics with my iPhone - not the greatest quality.

Also, subframe is sandblasted just needs to get picked up and slapped on, so I can start on S13 coilover conversion on S14 arms..

My wallet hates me.

Soo the only reason I was using the M3 E36 dash was because a stock one cost a fortune in good shape. Until I met an old guy who lives a few streets over from me and he hooked me up.

'72 240Z Dash - professionally restored
Heater center vent
Centre Console
All necessary tubing
BNIB dash side vents
Glove box
Dash to windshield trim
Dash harness (not needed I'm doing new gauges throughout)
Tail light finisher pieces

Enough speak, more pics.

Image
Image
Image

Also started fitting the S14 suspension

Image

And fabbed up some arms to hold the front on rotisserie.

Image

Soo I got an email from the guy that I bought my dash from about a hood for sale out in Brantford. I headed out there after work and met Chris and Rob - couple of bro's that have a pair of Datsun Z cars - one of them RB swapped. Cool dudes - sold me this hood for $50 :O

Image

Then I got to work on the front half of the rotisserie - s'all done. The rear half will be done up on Tuesday.

Image

Soo Tim is pretty good at photochop and made this for me.

Image

I'm a fan. This will happen + spoiler + black window trim - headlight covers.

Joe came over last night and we talked about expensive things..

1) 4-6 point cage, X bar tied into the rear R34 Subframe mount, 2 to strut towers, harness bars across. Tucked to cnt-hairs width from the roof and sides.
2) R34 rear subframe mount.
3) Fender brace that runs along the dogleg and around tucked to upper rad support and back around the other side (Beginnings of a tube front end).

Cage looks a lot like this..

Image

And rear subframe mounted alot like this:

Image

PIG ROAST!!

Finally got off my ass and finished the rotisserie.

Rear welds are fairly solid.

Image

Image

Need to bolt the arms to the T-bar before I try spinning it lol.

For those who care.

Almost *THEORETICALLY* have it figured out how to rock a fully counterweighted crank in a KA block with KA piston.

Rod is out of a Ford 5.4 Modular Motor, longer rod than a KA by about 5mm. Bushings need to be drilled out or replaced, or the KA piston needs a 22mm pin instead of it's 21mm. Crankshaft is a L20B/Z20E/Z20S U60 casting.

The other options I have listed include a Toyota Celica 20R 90mm Piston with various rods that will work - LS1, Viper V10, Ford w/ Chevy Pin, but I would like to try it with the KA piston first.

Braaap.

Image

In due time, after some paychecks, I'll make this happen and post up how it is.

Had an hour or so to work on er tonight..
Also had a package come in the mail. I <3 when that happens. Todays xmas present was a Q45 90mm throttle body+tps (thx godrifttoday)

Couple of comparison shots with a stock KA ~60mm tb..

Image
Image

Bolted er up.

Image

Spun er right round.

Image

Primered er up.

Image

Including my freshly blasted subframe..

Image

Most productive hour of my day :D

Had a few hours to work on the Z (I need a good name for her)..

Started with one of these..

Image

Drilled a crapload of holes..

Image
Image

Cleaned the bish.

Image
Image

Primed a bit

Image
Image

Also, bought one of these to complete my modernized suspension - JDM S14 swaybar 27mm w/ JDM S14 TC brackets. Also doubles as a rad mount and I can now order S14 sizes with install ease.. Not bad for $45 lol.

Might work on er again tonight and see how far I gets :D

Sorry for the delay boys..

My co-op term ended so I took the gf to Santa Maria, Cuba to celebrate. Things got silly and we had drinking team tshirts made up for the group lol.

Image
Image

Did a bit more cleaning up on the underside the day I got back.

Image
Image

Started on the passenger side.

Image
Image

Made plans to have some guys come over and get both floors done on Monday night. Monday morning on the way to work going about 80 clicks down a street, this happened. I had to countersteer and the jeep was on about a 20 degree angle while going straight down the road. Scary ****.

Image
Image

Insurance doesn't cover mechanical failures. Ghey. Tuesday morning picked this up from my buddy JP for a good deal - should be a fairly sick daily.

Image
Image

2002 Sentra SE-R Spec V
6 speed, LSD, bunch of new ****.
Ksport Kontrol pro coilovers. Height and preload adjustable, and 32 way dampening adjustable, with camber plates with pillow ball mounts.
Jim Wolf balance shaft removal kit
Stillen Intake
XS-Power header
BC cams
Rota slipstream wheels, with 225/45/16 kdws on the back (90% tread) and 215/45/16 rt 615's on the front
Nismo lower tie bar
Kenwood deck with Ipod
OEM nissan roof racks with back rack, and snowboard attachments
Magnaflow catback exhaust
Vibrant flat black muffler

Exams are almost done so I got antsy.. ZEDD Findings Floorpans took soo much work to fit, I was mildly ticked.

Image

Mocked up Sentra front coilover, S14 arm + spindle - Time to order some HSD S13 coilovers and make some camber plates.

Image

Cleaned up drivers side front well tonight - 3 more nights of working like this and the car will be entirely primed :D

Image

Got to cuttin and cleanin last night, got some fittin and weldin tonight.

Image

Car is going to Adam's place Thursday night to start work on the frame rails, R34 subframe mount, camber plates and possibly a cage, so I got the entire car primed. Floors are only tacked in as they are coming back out to weld in the rear subframe mounts.

Image

Woohoo - best update so far :D She's in Barrie for the next while getting **** done.

Image

Been super excited to get the Z back from Adam so I thought I'd try my hand at Photochop.

Never used any sort of image editing software and this was done on free Paint.net program so it's by no means good but it's a decent idea what I'm going for..

Image

Going up on Wednesday so I'll snap some pics of updates..

Also, how the car was about a month ago for comparison..

Image

Food for thought..

Image

Thanks to my buddy Matt for laser-cutting these at work :D

Dude this is looking good! Very impressed :lol: a buddy will really get a kick out of this build, he loves the old z's. He has had a few 280z. How are you gonna get the z33 tranny on the ka? Bolt right up? I know you can run an rb flywheel and z33 clutch on the ka, didn't know about the tranny

Thats a secret until I finish it, but with adaptor plate it will bolt up with zero machining to bellhousing like most companies need. :D

And all I need to make it is my drill press with a few fancy things.

I got my Z33 tranny cheaper than people sell their KA trannies :D And its equivalent 6 speed beef with a VR4 Getrag, T56 etc.

Definitely - I'm going to price out getting it CNC milled, and then do a Interest Check / Group buy on them.

Is the single slammer tranny the same as dohc?

True. I would offer the adaptor plate but the mount would be up to the buyer as I don't have a S13 to R&D one.. There are adaptor plates for SR motors to Z33 that come with tranny adaptors so I'm sure that could be used for S13's.

Supakat just read ur build - nice man!

Yep - absolutely no intention of selling the Z when its done.

Just finished the 3DCAD model of the adaptor plate - getting a cnc quote from Stumark and Precision in the next day or two. Obviously the price will be better based on quantity so I asked him for a quote on 1, 10 and 50.

Update of the day.

A smart fella and I have been talking about a bolt in, fully counter-weighted crankshaft for the KA24 motor.

It will shorten the stroke and displacement of the motor, but will be super rev happy - with machine work and fully built motor possibly up to the 9000 range, fully counterweighted (yay) and CHEAP (yay yay)..

Damn Brian Crower and his $$$$$ FCW crank.

I'll share once I get it started and calculations figured out. :D

For those who care.

Almost *THEORETICALLY* have it figured out how to rock a fully counterweighted crank in a KA block with KA piston.

Rod is out of a Ford 5.4 Modular Motor, longer rod than a KA by about 5mm. Bushings need to be drilled out or replaced, or the KA piston needs a 22mm pin instead of it's 21mm. Crankshaft is a L20B/Z20E/Z20S U60 casting.

The other options I have listed include a Toyota Celica 20R 90mm Piston with various rods that will work - LS1, Viper V10, Ford w/ Chevy Pin, but I would like to try it with the KA piston first.

Braaap.

Image

In due time, after some paychecks, I'll make this happen and post up how it is.

Thanks man - I think I'm leaning towards the Wiseco 10.5CR piston 89.5mm bore with 5.4 Ford rod.

Gives me a CR of 8.998 when couples with a 0.040 Wiseco head gasket. Should set me up for ~400 whp at 17 psi @ 7000 rpm, higher with lovely available rpm's but I can't even speculate what whp it'll be.

Well it is still a Nissan/Datsun crank and came in L20B, Z20S and Z20E motors -

Datsun 610
Datsun 710
Datsun 200B
Datsun 620 (1976–1979, 110 hp)
Datsun 200SX
Datsun 510
Datsun 720 (1980)
1979-1981 Datsun 510
1979-1983 Nissan/Datsun Bluebird 910
1981-1984 Datsun 720
1980-1986 Nissan Caravan/(Datsun) Urvan/Nissan Homy E23
1986-1997 Nissan Caravan/Urvan/Homy E24
1979.10-1980.11 Nissan Laurel C230
1980.11-1984.10 Nissan Laurel C31
1979-1981 Datsun 200SX
1981-1986 Nissan Stanza
1985-1988 Nissan Pickup D21

So it is pretty much readily available. RockAuto has them for $133. I'm getting mine fully balanced, polished and knifeedged for ~50.

How many cc's will it drop? I am like an old SBC person now, "There's no replacement for displacement". But i may add, "except for boost".

It will put it at 2164-2187 CC "displacement" and if you port your combustion chamber like i am and run a standard 0.040 head gasket, there is effectively 2453 cc of uncompressed volume at a CR of 8.448. Turbo Perfect :D

Damn nice project. I like your outside-the-box thinking.

<red-neck accent> Damn Canadians think they can come in here with their first post in these USA KA-T forums about them JDM cars, re-engineer the damn JDM motor with USA and cruddy ol' Datsun parts and make it work better. Sheeesh! </red-neck accent>

Actually, that's fine work there newbie. That ish is so awesome. You make my dreams come true. You must get some nice paychecks to support toys and projects like that. I'm envious of your skills, your cars, your paychecks and your ingenuity. If only I had the time, money and inclination. Pardon me if I've embarassed myself.

If you sell the VQ trans to KA adapter plate and I like it, count me as a buyer. If you don't sell it, or after a comfortable run, please donate that and all of your CNC designs to the world. You can post it up free somewhere on the internet. How nice would it be to have a fully modeled set of freely downloadable 3D models of anything you like? Need specs for a KA24DE engine flange? Sure. Nissan FS6R31A transmission flange? Got it. Thank you for sharing. Please share more.

Pics of said combustion chamber and engine parts and assemblage, please. Are those cranks steel or iron, forged or cast? If it's forged steel like the KA, I'll do that on the good block that I have to replace the bad crank perhaps.

Thanks again for such amazing contributions.
