Which road to take next ? air vs fuel

[rocafellafw]

My car is finally pretty stable and I've saved up enough for my next round of mods. Before I purchase one or the other I'd like to see everybody's choice of parts I'm looking at

I recently made the mistake of buying a o2 dump thinking it would help my creep but I from what I've been reading it might just make things worse. So before I found out the o2 dump would make things worse my original plan was to finish my complete exhaust system while I have everything apart to do the o2 housing:

Forced Performance Exhaust Manifold + Gasket & Studs
EM to turbo Gasket + Bolts
Turbo to o2 housing Bolts

Which came will come to about $360 ish. All which would be added on to a E3B16 o2 dump, Apexi N1 DP and full 3" exhaust.

Last minute I backed out and started to think maybe I should go the fuel system route to just support what I'm already creeping to (18-22psi) and purchase a SAFC II, some used 580 (650's if deadtime is no issue w.a SAFC) which would be logged with EVOScan + UEGO I already own which should come around to about $385 ish being injectors are going for about 120~. So any opinions or suggestions would be greatly appreciated on which route I should take. Thanks

You know technically you could fix your boost creep with a whole lot of porting on the turbine housing. Personally, I would just do the fuel mods, and then turn up the boost controller to whatever boost the turbo is currently creeping to and call it a day, your intake temps might be a little high though since your still on the stock sidemount.

Well I have a front mount I just need to fab up some brackets. I'm definitely going to port the wastegate exit when I install the o2 dump. Still looking for more opinions, I'm leaning toward fuel mods, how hard is SAFC tuning ?

If you don't have fuel, you should not upgrade your air. Simple concept.

I couldn't have said it better, I'd rather run rich a little rich then alot of lean.

Thanks guys, what's the highest size injectors I can go with deadtime adjustments not being a issue with just a SAFC ?

 

[airmail96]

most people say beyond a 650 is pushing the SAFC

Iv'e pushed 680cc on pump gas...

With e85, ive successfully tuned 750cc injectors
