turbo question

[clem]

just added the t3/t4 to my car i didnt do the fuel upgrades yet rit, rite now the boost it set low i wanted to know how much boost can i run on the stock fuel system and still be safe ? the car sounds great but am kinda scared to hammer the bitch cause theres a fear of blowing up !

You are most likely safe up to 14 psi, but you might want to keep to 12 psi for peace of mind. What's your wastegate spring?

[clem]

its a 38mm wastegate and the spring is 8 psi i think,i was wondering when i turn up to about 12 will i feel a huge difference now that i have my t3/t4 and do u think i will have traction problems ?

[JekylandHyde]

There is a HUGE difference between 8 and 12 psi ... could be as much as 40 rwhp!

TRaction be an issue? I have no idea what your traction set up is

[nepopolus]

eh mabe a little but mr2 are not exactly known for loosing traction that easy

[Gairloch]

^^ on decent tires that's true. Crappy tires will take your nice drivable MR2 and make it seem like the car has been watching too much FormulaD.

i would prob check with ats

see if they have a 550cc rom tune for a t3/t4 (and also get the injectors)

[JekylandHyde]

T3/T4 .... there are many different configurations.

There is not just one "T3T4."
