Going to Turbo My Ka24de Need Suggestions/Help

Post by 95s14Zinki »

ok im doing ka24de-t in my s14

t3t4 turbo

front mount

255 pump

should i do the 370 sr injectors ?

and i know im going to have to do a tune....

im thinking of running 7 or 8 pounds of boost with a external wastegate

im only lookin for around 250+ hp if possible i want it to b semi reliable

STOCK INTERNAL KA 24de

Heard You Can Push 300-350 Hp On Stock Internals from this site? Is This True?

My Compression on the motor rite now is in the 160-170 on each cylinder


just wana get some ideas /suggestions from some ppl before i go and do it


dont say go sr please lol i already thought of that but i dont wana get ref'd i live in valencia cali and they are dicks out here sr is ez ref.... ka i can get away with it

Get 550cc, z32 mafs, clutch, gauges,wideband....I can keep going but I've been annoyed with these threads

and you may be able to get away with 7 psi after you add ^^ you can stay factory maf up 280-300. but I would atleast go headgaset/ arp headstuds. pistons would be a good Idea too

Factory mafs are good to 250 maybe, same for 370, they can handle 10-12 psi on t25 or 28...

I wouldn't worry about internals, gasket, studs under 400 especially with good compression

you need some way to tune it otherwise have fun with a blown engine. I wouldnt trust hypereutectic piston with boost. your car Big risk. you did ask for suggestions. factory s14 maf will hold 300ish with proper tuning. some are going much higher you just switch to a map once it maxes the maf (running both).
your set up as is will blow up and you may as well have gone sr because you will spend 4k fixing all the stuff that broke. just sayin

This is quote full of fail. Let me help:

1) our stock pistons are not hypereutectic, they are a traditional cast piston. Hypereutectic is a cast piston with high Si content to reduce thermal expansion. More popular in the NA V8 crowd...

2) the max up extracted from a maf has nothing to do with "proper tuning". It measures the amount of air flowing over it, and at a certain amount it can't read any higher. A tune has no effect on this limit. From PERSONAL EXPERIENCE the s14 maf is maxxed out at 250hp. On a t28 at 10psi I was right around 230-240whp and saw maf readings of 5v (max) under full boost.

3) map is not necessary at all for your setup and requires the use of standalone engine management. A n62 maf is good to 500hp. This will be plenty for your setup.

Here's my reccomendation:

Go read some build threads and see what parts you need based on other peoples setups. Buy the parts and install them. A good start would be an n62 maf, deatschwerks 550cc sidefeed injectors and an Enthalpy ROM tune for engine management. A good clutch is also a must. Stage 3 to be safe.

ok. 97-98 pistons are hypereutectic or at least I was under the impression they were. I was also told most s13s had cast.
I also never said the maf was required for proper tuning. that maf can take that horsepower with correct tuning. to each his own. I dont know half the options there are out there I just know what I have seen and yes I may be a bit to cautious when it comes it the engine.

Sounds like you need to do more research

i am home on a friday night trying to make it interesting by going on ka-t and all i see are these threads. it is getting really annoying seeing a new thread and when i read the first two lines the hair on the back of my neck raises and i go back to the previous page. there is a sticky on this site specifically for our motors but all in all, turboing an na car is going to be the majority the same for all other motors. so if you google how to turbo an na motor or something similar, you will research and learn something rather than asking the same question that 8 million other people asked and get a lot more retarded misguided
replies than factual intelligent responses.

i personally think that when someone gives up on researching something that they do not know and asks as an easy way out, they have already given up. everyday people go to school or read to learn something, please apply this to your everyday life and you will be amazed of how much your brain will soak information.

i see you have common sense as well. i have to rant about this. i hate when people install a product wrong and blame the manufacturer. i am speaking in terms on xtd specifically. i was reading a review where the kid bashed the hell out of it because the springs on the disc were eating up and two of them came out. the dumb f*ck put the disc in with springs facing the pp. idiot! i was running an xtd clutch for 1.5 yrs. change out the disk to act and still running with xtd fw. i am going to see about selling my fw because i am going to run the rb fw.

Do you live in new Mexico by chance? If so, you should go hang out with tom550, I'd bet you'd get along great!

Here's what you aren't understanding:
THE MAX HP A MAF CAN HANDLE HAS NOTHING TO DO WITH PROPER TUNING. if you have a **** tune, an s14 maf will max out at 250hp. Well guess what, if you have the worlds best tune, your s14 maf still maxxes out at 250hp!!!! It's a simple concept. You can't tune a maf to read more hp. So no, not to each his own, this is fact.

Wouldn't get 400+ on stock internals but for that price ain't a bad little setup....could easily get that less than 300hp goal

THE MAX HP A MAF CAN HANDLE HAS NOTHING TO DO WITH PROPER TUNING. I said it has nothing to do with the proper tuning! Mafs have no way of seeing anything to do with boost. so it is a good Idea (again not saying needed but most boost controllers come with it is a map) to have the map as a secondary sensor. when the maf maxes out you clamp the voltage and swap to the maf for air readings this will be at higher rpm with higher boost. also there are set ups on this site that say the same thing and they do know what they are talking about. I may not know alot about 240s but I do know a thing or two about turbocharging a car and building a motor. an if I see a weak point i dont take chance. but its cool think im a dumbass and write me off. you will probaly read two word and say maf has nothing to do with tune. a maf is another sensor to be used as a tool.

That is not true and not a fact. The more efficient your setup, the more horsepower you can make on a given mafs. The mafs can read up to a maximum mass flow rate. Lets say you have two ka's and both of them show a maf voltage of 4.8v wot.

One of them is running 9:1 afrs/really retarded timing and the other is running 12:1 afrs and mbt. They are both maxing out the mafs but the latter is making atleast 20 more whp. A good tune and good volumetric efficiency will allow you to make the more power for a given mass flow rate.

The only fact is that an s14 mafs will ~max out at some mass air flow rate. I would say the stock mafs maxes out around 250whp, but the actual amount will very with the efficiency of your motor.

98blackkat, I know what you are trying to get across. The set up you are talking about is very rare on this platform, and few here have a management system that can clamp the mafs and tune via map. I can tell you still don't fully grasp all the concepts though.

Thank god someone at least understand wtf im saying. I know Im not explaining it well. and the details I dont full understand (I can admit that). thats why I have people who have done this alot more then I have (roomate, peps at work that tune the cars) . I also am trying to learn. Im used to my '68 mustang, and friends '95 cobra. so yes 240s are not my normal thing.

I know it wont hold 400hp in stock form,but lets face it.it will eventually blow up,or hes gunna want more power and do a full build.

ok and may have been wrong on the metal content of the piston but "Cast pistons depending on the condition of them have handled past 270HP and into mid 300HP levels(risky)" they are still cast.
