You might want to do a search or ask in the 'All Motor' section, they know alot about this.

I haven't heard too much about headgaskets to raise compression, lower it definately, but not raise.

Try the Nissan dealer though.

dont worry about it

SCE Gaskets makes a copper one in different thicknesses.

I thought the company that wanted 50 orders would be making a multi-layer metal gasket? I didn't pay attention much, but that's what I remember...

I have found best results with a stock gasket and ARP or stock head bolts.

Same here. I've seen over 30psi on a KA24DET with the stock gasket and ARP studs. However, when the engine still had stock bolts instead of ARP studs, the gasket blew at 18PSI... my personal experience.

That sounds about like how Jay (PSI240SX)'s car was. He ran ARP studs and stock headgasket. However, I think if you O-ring it with a copper head gasket, it will even be better. Jay still had to replace his head gasket every few weeks it seemed. Although, 30psi will do that to a stock headgasket

Backyard has those for sale.

Actually, Jay told me himself that he used stock bolts and not ARP studs. I think he would've never needed to replace the headgasket had he used ARP studs instead.

o-ring with a copper headgasket is indeed better, but will have very poor sealing against water leakage in the long run (10,000+ miles). Even the best sealants wouldn't seal water for too long. Constant expansion/contraction, temperature extremes, etc... are very harsh on the sealant used on a copper gasket.

The best combination (reliability and performance considered) in my opinion is a stock or Fel-Pro headgasket with ARP studs (and no o-rings). I say this because I've actually tried: stock gasket + stock bolts, copper gasket + stock bolts + o-ring, stock gasket + ARP studs, stock gasket + ARP studs + o-ring. Just plain stock gasket + ARP studs was by far a better combination than all of the above.

This is what I run and I agree. I like it cause I hope the stock gasket will blow before it melts my pistons.

Oh yeah, I forgot. I've actually helped Jay replace his headgasket before....but I just didn't remember.

So you've tried all those combinations? Wow. That's good to know! I didn't know anyone had tried those combinations before. If you don't mind me asking, what all do you have done? How similar is your setup to Jays? You also said you ran 30+psi...what exactly did you run? I think the most Jay ever pushed was 30psi, but boost was falling off because his turbo was too small. Have you run in the 1/4?

Whats the difference between sets?

A friend and I ran 2.1 bar on an almost identical setup as mine. The only difference is that he has 96lb injectors, its respective JWT programmed ECU, and an Apexi s-afc. I have 50lb injectors with a JWT programmed ECU, and no s-afc. I max out at 14PSI without a fuel pressure riser (fmu, pressure reg, etc...) with the 50lb injectors. His injector duty cycle reached 95% at 2.1 bar (just a wee bit over 30 psi), so we didn't push any further (detonation at 30psi isn't very forgiving

). I have only done 1/8 in San Diego (8.9 ET, embarrassing 60ft), but not yet 1/4. I don't think he's dynoed his car yet...i can't wait until he does. I know I'm waiting for a larger fuel system and some means of tuning it before I do go to the dyno (also thinking on a DIY wideband O2 monitoring system).

He also has a larger turbo than me.

Everything else is the same on my car and his:

Different sized studs on the main and the head studs. The head studs fasten the block onto the head. The main studs fasten the bottom end (crankshaft onto the block main and main caps...one solid main cap in the case of the KA24DE).

You don't think who dynoed their car? Your friend? Or jay? Jay dynoed 412 HP and 412 lb-ft of torque to the ground. But he sold his car about 2 months ago.

I meant my friend.

Would you happen to know how much he sold the car for?

I don't know the exact price, nor do I know if he wants anyone to know, but I believe it was in the $12-$16k range.

Is this the same Jay that now has an S13 with an SR??? I thought it went for 12k, but he kept the wheels.

That would be him. Like I said, I honestly don't know what he sold it for. But I know it was within that range that I said.

So in that case we are all just talking about head stud kit?

For the gasket issue, yes, we were talking about the head studs. However, I would strongly recommend using ARP main studs for the bottom end too while you're at it. It's priceless insurance...

I just bought the ARP head and stud kit (I think I bought them from pornflakes). They fit perfect and are beautiful!! I would defiently recomend then to anyone building a KA-T

Yep, that was me. I'm glad you like them.

Thanks for the compliments too.

Post by **matt0941** » Sat Apr 05, 2003 1:32 pm

Ok see thats the thing. Well I talked to the guys at the link I provided and they were pretty nice (think it was dennis) and gave me a price of $165 for the APR head stud kit.

But why would you recommend the main stud kit if one were to run a stock bottom end?
