4. Pics below show that this head is not a 240sx head, but as someone had pointed out to me, it looks to be a Nissan Frontier head. Note the "missing" 11th and 12th cam caps near the rear of the engine. I looked up the speedometer clusters for both and the 240sx cluster appear to redline ...

This thread sure is all roses and cute puppies...haha. :lol: This all SEEMS like a good thing, but I assure you - None of this will help you or I, financially, in the end. That is, if you want to work hard, be well paid, and enjoy the fruits of YOUR labor. Think of it like this - Best way I've seen ...

I think that wastegate tube on the manifold is the issue. When the exhaust velocity REALLY gets going (you know, around 4500-5000 or so under full boil...right where you're having a problem)...it's hard to make it flow in a U-turn, rather than up and out the collector. I think your only option will ...

DO NOT turbo your car using stock injectors and stock fuel pump. You're gonna run out of fuel at ~3500rpm under ANY boost. Couple that lean condition, with WAY too much timing...even with the base timing retarded at the distributor...and you're sure to blow the thing up, quickly. ... You've got the ...

I would wager that my car has seen more track miles than almost any other KA-T setup on here...and I've never had an oil starvation issue. Journal bearing turbo (Garret T3/T4 50-trim). 320rwhp. Stock block. Doing track events on this setup since 2004. I run sticky street tires, with average gees of ...

Wastegate dumped, or re-routed to the exhaust? If it's not dumped: Could be, that the manifold design is only "OK"...and as you reach the full flow capacity of the exhaust/downpipe...the wastegate tube "backs up" (for lack of a better term), and you get boost creep. Try dumping t...

It's possible to have a VERY reliable stock-block KA-T at ~300rwhp. But IMO, it's NOT possible with an AEM. You'll screw with it someday and it will detonate *just a little*...and that will be the end of that stock-block motor. I beg to differ on this regard. That all depends on the person who owns...

Safe bet with AEM standalone? ... So Is it possible, with a healthy tune, to keep this much power around for a good amount of time? It's possible to have a VERY reliable stock-block KA-T at ~300rwhp. But IMO, it's NOT possible with an AEM. You'll screw with it someday and it will detonate *just a l...

What code are you getting? 32 would be "EGR not functional", and would be tripped by the temp sensor. The resistor trick works 100% of the time for this. The check for code 32 works like so: The ECU *thinks* there should be EGR flow entering the intake manifold (under light throttle, cruis...

^^^ What these guys are talking about:

Remove valve cover, see if your upped guide is broken -->



Either way, broken or not...remove it, and throw it away.

I'm in Orange Park...nice area. Hit or miss on the Westside of Jacksonville overall, but Orange Park is nice. I'm not very active in the 'scene' anymore...only really take the car out for events, not car shows or Fri/Sat 'meets'. Hit up 240SX.net, like someone else already mentioned - Good group of ...

IMO, the 45/50/56 columns of your timing map is WAY too aggressive for a stock block. 18*, between 2400-5200...is a lot. Like somebody already mentioned, too much for peak TQ (which is peak cylinder pressure). My JWT tune runs ~14-15* at throttle tip-in (3000rpm or so), and dials in a degree after p...

There's a couple of those running around...here's one vid of a drag race with a Ferrari (from 5 years ago).

^^^ The point of a fuse between the battery and the new connections under the hood is to prevent a fire.

If the wire you used to relocate the battery was to fray, and ground out...you'd have a serious potential for things to melt/fry/burn.

Better safe than sorry.

1/8" BSPT

Close to the more-standard 1/8" NPT...but it IS different.

Unless I'm mistaken... You can use the auto one - Flip it around backwards, and I think then only 2 of the 4 chassis bolts will work...but it will do the job. Maybe you have to drill a new hole for the transmission mount as well. I ran one for a while after my 5-speed swap, and remember that it was ...

Nice work on the turbine.

(BTW, got your e-mail from last week...but my e-mail server/app on my phone sucks...so I never responded)

Anyway, keep it up!

T3/T4...50-trim, or 57-trim....63 A/R turbine. That should net you a reliable 350rwhp at ~15psi. Don't get hung up on on boost level - Other than intake air temp, 380rwhp is just as hard on the motor at 20psi or 10psi. With turbos, you're not gonna get it all...super fast spool AND 380rwhp at low(is...

Why would you need the battery cut off switch to be connected to the alternator? Id hope anytime you'd be using it you'd have the key off anyways. Maybe im weird though. If your car is on it's roof on a track, the kill switch should cut it off...all power, and the engine. If the engine was still ru...

Don't overlook tires...aside from air resistance, rolling resistance will be your next biggest gain.

Also: Transmission and differential fluids.

I know this is an old thread, but how do u like the HPS+ pads ? I'm very easy on brakes, for some reason...? SO the HP+'s have worked out well, no fade even on back-to-back fast laps. I used HPS before, and they were only "OK"...the HP+ seems to be a better compound for track use (and tha...

yea but i think the stock afr's are really lean them selfs from factory. No. and couldn't the stock ecu compensate for being a little richer? No. Not with 37% more fuel being sprayed, without the ECU knowing it. These cars don't run a wideband 02 sensor...and the O2 is ignored under heavy load / WO...

Compressing air heats it up...no way around that. The more you compress it, the more it heats up (generally speaking). Not only will the larger turbo have a more efficient compressor...but it will require less boost. Less heat is ABSOLUTELY the thing to strive for. ...then we can get into the effici...

How does the trans survive?

That was an issue with one of the current "production" electrics (can't recall which one...Tesla, I think). They went to no gearbox, or a direct drive setup.

Regardless, I like it.

Are you running an underdrive pulley? That would keep the RPM's down on the accessories...and might help in your situation.

I've never had an issue, and run an ASP crank pulley.

I ran the NGK's for YEARS with no issue...they lasted through many, many track events. They were just the standard NGK 'blues'.

I replaced them (for no reason other than preventative maintenance) with a set of Magnecores...which are very nice.

You'll be fine with either one.

I've always used .55...it's close enough to the real world max numbers that people have empirically proven. ...i.e., if you do the calc for 370cc injectors - - - - - > 370/10.5 = 35.2lbs/hr 35.2 x 4 injectors = 140.95 140.95 / .55 BSFC = 256.3 ~256rwhp is just about the MAX you could squeeze out of ...

^^^ Rubber gets old and cracks, especially with heat. I had a couple sets on my intake manifold before I drilled-and-tapped it, and every year or so...I'd have to replace one. It was usually in a gas station parking lot, in the rain :) . Silicone vacuum caps will hold up better, but they can still p...
