I'm just wondering what kills a bone stock motor. I have a b16a2 JDM. It is tuned for 10 psi and makes 270hp. The turbo is an 18g greddy turbo.
Does horsepower range kill the motor or is it psi? It is tuned so dont say its tuning.
I want to turn the boost to 15 psi. On a greddy18g 15 psi is about 300-320 whp. Do you think the motor, rods, rings, pistons can handle it. This is my race car.
Bone stock: stock rods,pistons,rings,cams,valvetrain,headgasket,tb,i m. Nothing is done to the motor.
I have raced it 15 times and It is harder than it seems to get a fwd car to straight fast. Best time 13.4 1/4 at 112mph with a 2.8 60ft.
I run the car off the wastegate spring. I was just going to order a 1 bar spring.
Please no stupid responses.thanks

Well if we cant say tuning then i'll go with more HP if your getting 400whp out of a stock B series it will be just a time bomb waiting to happen, although if you are running high boost out of a small turbo and not making much power that is also bad because the IAT's will get very hot and Cast pistons like to melt

cylinder pressure kills engines... Its all in the tune and parts you used

Neither, and as for tuning... there is tuning and there is tuning... let's also not forget operator error. Keep flogging a heat soaked engine because you're excited, ring lands make a brittle pinking noise, and all of a sudden the car "wasn't tuned correctly."

Not *exactly*, Stith, although high enough cylinder pressures go hand in hand with the combustion temperatures/densities/pressure that knock occurs at.

si I could run a smaller 18g turbo at 15 psi and make 300 whp or use my t3 60-1 at 10 psi and make 300 whp. So, I could turn the boost up on a smaller turbo?

I think you'd get bigger gains spending money on tires + suspension and working on dropping your 60' times, and while you're doing that you can read more on turbocharger theory. This stuff takes a minute to get familiar with, and you shouldn't rush it.

What's your suspension setup? If you are at all lowered, you do have camber kits and the camer is back to zero, yes?

Does your engine code say B16A2? Or is it the 2nd gen (SiR-II) b16a? JDM engines dont have numbers after the code. Youve probably got the SiR-II like me. It features factory pistons with a bit more compression than any other b16 model. Heat will kill those cast pistons. The rods on a B16 are quite beefy but id at least upgrade the bolts to ARP or any other good aftermarket rod bolt. They will give out long before the rods will.

If you plan on keeping this engine for many years, reliabilty becomes questionable. If this car is your baby and want it to last for 20+ years, dont half *** anything, even on a 300whp setup.

I got 24" slicks and managed to get my 60fts to a 1.7. But having trouble holding the gas pedal down and shifting. The 2 step system. I have another car that is my daily driver. 18 psi t3 60-1 maxing out my 720cc injectors. I cant drive that anywhere on a track.
So, thats why I'm staying stock for now. I just dont feel like pulling the motor for rods and pistons.
I' m now at 10 psi, it is a jdm motor,10.4 comp. I due a compression check regulary. 240 across the board. It makes 270 now once I hit 12 sec I'll want more. So, 5 psi should get me more. Car weighs 1950 w/driver. I trapped 112mph.
I just have to learn to drive. Once I due I hope to go to 15 psi.

1.7's, yet your best run is a 13.4 with a 2.8 60'?

Uhm...

you need to work on your launches/controlling wheel spin.
my best 60' in my N/A H23 2,900lb 'lude is 2.2XX

wheels/tires and suspension FTW
