supporting mods for vf39/vf43 on an 07 wrx

Im sure this has been asked plenty of times, but what is needed on a 2007 wrx to run a vf43, i heard they dont need bigger fuel injectors or even a fuel pump.
just a 3'' turbo back and maybe a protune for my cobb ap? and a tmic/fmic

 

Im about to run a vf39 and my supporting parts will be:

3" DP 3"catback
pinks
EWG setup
i might go for a bigger TMIC

and...might be few more things that i cant remember

 

AtlxPat, all you need to do is have a high flow cat or catless downpipe and catback that is 2.5 or 3". the downpipe should be 3". And engine management. TMIC from an STI will work.

 

most important thing.

 

Should not need injectors. Your stock ones flow more than pinks

 

Yea i already have a full turbo back and cobb ap v2. the cobb exhaust tapers down to 2.5 but im gonna get that changed to a full 3'' at a muffler shop

thats great to hear!:coolugh:

 

'02-'05's need injectors and a pump but '06/7's don't they were upgraded oem already

 

Yeah, i already knew that about 02-05, but didn't know that about 06+.

 

I would still look into doing a fuel pump as it is cheap and easy insurance Not only that when you decide to put a BIG turbo on there one day, it is one less thing to worry about!

 

Just listen to what Strayen said. He's got that same setup and it runs very nicely and put down good #'s.

 

what is he running, vf39?

And yea i forgot to add fuel pump to my list.

 

Ped and I installed the fuel pump in a little under an hour. It's pretty easy once you rip the back seat out.

 

i think his is a 43, same difference. just bigger wastegate to eliminate issues from the 39.

i wanna do a externally gated 39/43 on my swap..... whenever that day comes.
