Going from Cobb Stg 1 to 2.5 what stock stuff do I need; gaskets and stuff

AdamRX · 11-16-2004, 03:08 PM

I'm adding a gutted stock uppipe, helix catted downpipe, VF30, STi injectors, fuel pump, and a new inlet hose. I wanna get everything before I do this and by everything I mean the little stuff gaskets, rings whatever, I just dont know exactly what I need...Any advice?

I've read the uppipe faq by Una (thank u), but do I need to get all those gaskets? Or can I just get the four "main" ones; 2 for the uppipe and 2 for the downpipe? The VF30 and STi injectors are used, will I need to replace anything? I'm thinking I should replace the o-rings on the STi injectors, but is there anything else I left out?
Thanks Adam

Its definately worth getting new gaskets, you dont want to have leaks.. since you are popping in a new down pipe, might as well put a new one from downpipe to midpipe.

just my thoughts

I should be doing a similar install very soon as well. I'm already at stage 2 so I'll be adding the vf30, injectors, fuel pump, and turbo inlet pipe. I'd get new o-rings for the injectors, better safe than sorry. Sounds like you have all the basics covered. Good luck w/ the install.

It's always nice to use new hardware (gaskets, bolts, o-rings) when changing stuff. It'll assure you won't have leaks and have to do the work over again.
