Is it a straight swap from a VF35, as fitted as standard to UK MY2003 STi to a VF34 as is fitted to a JDM MY2003 STi ??

If so what sort of power increase could be expected with the appropriate mapping after the swap ???

 

2003 JDM doesnt have a VF34 its twin scroll

 

2003 Jdm sti have a Vf37 twin scroll .spec c ra from that year Vf36

 

You will be looking at 340bhp tops,
Anything over 340bhp and turbo wont last long fella.

 

theres not really any point going from a 35 to a 34. theres very little gain to be had

 

Why even bother swappin to the vf34 ? is yours shafted? they both top out at arround the same 340 horse mark,the 35 is faster spool up too i think?

 

Nope me gettin confused between VF37 twin scroll & Vf34........

Can a VF37 be retro fitted to a Uk 2003 STi ??
