Hi all,

I know this topic has been discussed before i just want to find out if anyone here is running same/similar set up as me and what psi are they running..

Chasis: Gen1
Motor: 2.0 Gen2
Clutch: Stage 2 competition
Injectors: 750c DW
Intercooler: ISR FMIC
Exhaust: ISR Catback
02 housing: ISR
Turbo: 20G twin stroll- ISR Evo8/9
ECU: SFR Custom tune (was tuned at 17psi on bk1 motor and 20g Turbo)

Since the tune was done on old set up and i have more upgrades to handle more power i wanted to know if i could up the boost to 20-22 psi?

I want to hit 400+hp. Should i look into upgrading CAMs before increasing the boost? I am located in Toronto and i dont really know/trust any garages that specialize in Gen coupes so i lf i can avoid upgrading CAMs/Pistons it would awesome.

Thanks guys

What's your boost at peak rpm? Hitting 20-22 is not much of a problem even with the BK1 stock turbo with a tune. Holding it to redline is another matter.

its only 17psi. bk1 motor had high mileage so couldn't push it further.
Did a bk2 swap and compression results were 155 +/- 2 for all 4.
After the swap i added FMIC & Cat back.

Adding braided sleeves for cold air intake tubing, heat wraping the intake manifold & 3 inch down pipe this weekend.

I cant think of anything else i need for safety before increasing the boost..

Stock, the BK2 motor supposedly peaks at 20 psi According to some BK2 owners.
But that was with the the original 19T TD04HL

With a different turbo the Dynamics change as to what you "should" be running.
Tune-wise (spark) you can push it a little higher due to the lower compression, but that's not accounting the additional fuel you'll need.
Get another custom tune.

With my experience, I don't trust Hyundai internals regardless if its a BK2 motor. I rather have the peace of mind that the conrod isn't going to snap in half (which happened on my first motor)
EDIT:... and the motor I'm waiting on parts for, to rebuild, had a gouged main journal.

Thanks, i don't trust the internals either although they are supposedly better than bk1....but my by how much and exactly why i have no idea..
