Stock gsr want to boost

[Mllamas10]

Im wanting to boost my stock gsr. My goal for this motor is make 350 hp but wouldnt mind a little more.
I have been reading around at different forums and they say that the stock internals should hold up to about 300 to 350 (correct me if im wrong) but I dont want to risk blowingit. My budget is gonna be around 5k for the build . im thinking of going with the 10:1 comp setup. Any advice is appriciated.

If you've got 5 grand and you dont wanna risk blowing the engine, you can buy a full-race turbo kit for like 3-4 grand. Spend the other grand getting a good tune and your good. Heres a good link for other info as well http://www.clubintegra.com/board/sho...546#post910546

You can hold 300hp with a good tune and will probably be reliable, but on stock internals I wouldn't push over 300 at all.

I think you can do a decent setup for 5k. Upgrading the rods and pistons would be a good idea, and if you're going to change the comp ratio a different piston is in order anyways. Any specific questions?

[Mllamas10]

Would it be a good idea to lower comp or just keep the same ? And what would be good pistons and rods? And are sleeves a good idea

[BambinoGS]

Lower comp would be safer. Get some eagle rods. Sleeving would be good for reliability by may not be nessassary

High compression (10.1) is great for boost, it spools quicker, takes less psi to make the same power as low compression. Just requires a really good tuner to dial it in.

You would probably be fine raising the compression as long as you have a competent tuner. Do you know what size turbo you want?

As for the pistons and rods I would go with CP pistons and rings with manley rods.

What are you planning to do with this car? Daily driver? Track? Drag?
I'm running a t3/t4 57 trim and it's just about perfect for a daily driver. It spools up just over 3,000 rpm's, so if you're driving normal you won't hit boost and you can still get decent gas mileage. However it is quite tempting to boost, therefore gas mileage will suffer a little. Lol.

A stock b18c1 can handle around 450hp daily driven, the only thing you gotta worry about over time are your valves since stock valves aren't heat treated to handle the extra heat the turbo produces inside your motor. 350 you don't have to worry about a thing. I've been running around 365hp in my bone stock gsr for the last few years, no problems. But if you did keep it stock and wanted to go more than 350 get head studs. Other than that 350 is safe.
