well if you don't want to spend a ton of money you can just buy a 89-91 turbo and a FCD. That will not be expensive and with a downpipe and exhaust upgrade you will like the results.

You can go with a bnr upgraded turbo for around 800 I think plus shipping and core, you could get a greddy turbo upgrade kit for 2500, or just rebuild yours for 300 or so plus shipping if it applies> Are you still using the stock TMIC setup or do you have a fmic?? because if your running the TMIC you may not want to upgrade until you get rid of that inter heater. If you just need a stock turbo till you have the cash to upgrade the turbo, fmic and dp(or modify yours) I have a spare s4 lying around for 100 bucks

bigturbo i would not recommend anything you just said without going to a $1500-2000 standalone ems system. Once you start talking about that stuff you are looking to spend 5-8k. Look at my sig and ask me how I know.

yeah thats true bukwild. You will need the supporting mods thats for sure. I always assume that everyone already knows that. You need a fmic, injectors, pump, and a stand alone would be best unless you go with a stage 1 or 2 you may not need the stand alone but will def still need the rest. Potolessuk no you cannot bolt a s5 turbo to a s4 manifold. You can bolt the s5 turbo and s5 manifold to your block but thats it. The s4 utilized a twin scroll setup(actuator and flapper) that the s5 doesnt thereoff the manifolds are different. The s5 is a little bigger from what I hear and has a little more to end but the twin scroll spools quicker. Thats why i recomend you use a stock turbo till you save up all the cash to get all the supporting mods for a bnr, greddy, hks or t04 setup. Got one for 100 bucks
