i boosted my car on a t3 t4 turbo, uprated fuel pump, injectors and a crome remap on 9 psi, it got 251 whp.

i have been doin alot of reading mainly from peoples experiences in america and from what i can gather you can run up to around 10 psi on stock internals. but after two weeks of drivingnow i have low compression in cylinder 2, missing, and white smoke puffs outta the rocker.

is this because we run in england ondifferent octane (97 octane)fuel making more power, and my engine could not handle the safe boost leveldue to a horsepower limit on stock internals rahter than psi limit on this sized turbo! hope this makes sense. any idea what could be the cause aswell, im gonna have the head off at the weekend!

 

Youre running 251 whp? What motor? 251 @ 9psi is a pretty big turbo.

 

b16a2 t04e t3 t4 turbo. is it more a hp limit then than a psi limit ?

 

here is apic of the dyno figures

yeah, it's more hp limit since different turbos size make different amout of power at the same psi.
Anyways, 250whp is the about the highest reliable hp range on a b16.

What type of fuel management are you running, since most turbo problems rise from a bad tuned.

 

have you heard of similar symptoms inother peoplescars?im running a crome ecu map chipped obd1 conversion harness 255pump 440 injectors, a guy called mark did the tune at thor racinghave a look at their website it near birminham england, this is one of the best tuners in england, see wat you think of the english,gota give it to the US thoughyou got much more happening and australia, new zealand and of course japan.

oh yeah and it only made 151 ld ft of torque is this low for a boosted b16

 

yeah, that is defiinitely low on torque. I have'nt dyno my car yet, but i have a turbo d16 set up making around 170whp and about 150 ft-lbof torque, so yeah that is low for a 251whp set up.
