Gt2871r boost stock internals

[slipxnxslide]

Ok so I am just about finished building my car and engine mods no internals done all stock internals but my question is how much boost can I safely run for a track slash daily driver not hitting boost as much while it being a daily driver, but what's the maximum boost I can run with stock internals and not frying the block lol like 16? 14? 18!!?! Lol please help!

is anybody else psychic and know what engine this guy is running?

if you're talking about a KA, i'm interested too. also, to a certain extent, boost is boost. max boost is basically the same from any turbo. assuming you're not running a tiny turbo that's overheating the air and causing problems.

he is running an SR hence the SR picture in his title, and i'd run 14 psi all day, thats what i ran on my stock internal ka-t setup with a 71r. and every turbo is not the same... 14psi on a 71r is less volume than the same amount of boost on a gt30.

[cdlong]

oh fuck, who pays attention to those things. i'm an idiot. just ignore me when it comes to turbos.

Head gasket and headstuds turn that crap up - 14 is weak.

Stock internal...who cares...better question is what supporting mods do you have? Couple of things that comes to mind that will blow your engine faster than stock internals...stock fuel pump, stock intercooler, stock injector, stock maf, stock ECU, the list goes on and on...

Case by case basis. Your tune is the determining factor.

15 psi on an sr20. The block is reliable at 400wp. 500 is stressing

I run 19 psi on my 2871r with stock block. It sometimes creeps to 20 psi. Obviously I don't keep it there all the time. I have my HKS boost controller and run 16 psi normally.

It's all in the tune and supporting mods that determines how much you are safe to run.

just make sure that it's tuned properly and you have an aftermarket hg.

Umm, negative. 1.2bar on a stock T25 will not blow your shit up, 1.2bar on a T88 will blow your shit up. Max boost is def not the same on any turbo.

we'll just ignore you all the time

bad comparison. I know what you're talking about but he won't. 1.2bar on t25 will make intake air temps too hot and will "blow" your shit up.. 1.2 bar on a t88 will run too lean and blow your shit up.

who runs a t88 without fuel + ems?

THIS! Additional info....

Just curious but when does headlift start to occour, everyone talks about how much their stock bottom end holds in every thread but i haven't seen much about after what point the headbolts/gasket gives.

[godsmack]

Well on higher boost you'll blow metal head gaskets around cylinder 1 cause the front lip sits slightly higher than the block itself and needs to be shaved. As far as the bolts just get apr bolts whenever you change the headgasket and you'll be fine.
