So far, these are the power mods i have done to my car. Im on a bit of a budget and need to know what to do next. Im not on a crazy power hunt,(with this car anyway ) but would like a solid 320ish power figure, good acceleration to 100 and minimum lag.

My car is a 96reg sti2 555 with 65000 miles

FSE pump and regulator
3in HKS cat back
Hayward and scott downpipe
HKS filter (being changed next week to box with panel filter, i know this is ****e)
Td05 16g turbo
Blitz boost controller

Would a scooby clinic remap be a good idea next, or do i need a standalone? Also i know my injectors are tiny so do these need changed? Finally, is there anywere in Scotland who could set my boost controller up properly cos the car seem a little bit lagy.

Any input and advice would be greatly appreciated, im beginning to wonder who to trust this side of the border

 

Seems like Andy F might be able to help you,

 

Yeah he supplied my turbo, but i dont realy have the cash for an ecu and map from him. Im trying not to spend to much on the car, its being sold at the end of the summer.

 

As you are in Scotland, I would recommend AndyF, some 550cc's an Apexi PowerFC and a secondary boost controller (maybe the Blitz controller you have) to take boost beyond 1.1bar. But that lots gonna cost around £700 for the apexi and Map, then plus whatever you can get the injectors for new or 2nd hand.

You should be able to get over 300BHP on 1.1bar, but I don't think 320BHP would be possible at 1.1bar, and the 380cc injectors are going to be on the edge.

 

Andy has my car set up to run 1.4bar peak using 380cc injectors until I can get some 550's. It required a slight tweak to increase the fuel pressure I believe. I get 98.2% IDC so they are pretty much maxed out

 

I take it a fuel cut defender and cranking up the boost that way is not recommended then?
