Hi i've an 04 sti with a HKS induction kit, and a 3" exhaust straight through, i also have a walbro fuel pump not yet fitted. Can anyone give me some direction on what is next, new pump in and re-map? fuel pressure reg? can i go with a bigger turbo? on standard intercooler? cheers

 

MD321T will give you around 430+ bhp with a re-map, injectors, and supporting mods.

Enjoy !

TD05/18G - 380bhp
TD05/20G - 390-400bhp

You'll need injectors after the 400 mark.

The 321H would be better suited for a 2.0L car, the 321T would be quite laggy.

 

A remap, quick. Driving with those mods on a standard map is asking for trouble of the expensive sort. You might also want to refit the standard induction tract with a tidy panel filter.

Standard intercooler will do a job close to 400bhp so you can go with a bigger turbo on it if you want. The one thing you don't want to do right now is just carry on driving it the way it is at the moment.

 

I agree with splitpin completely.

As far as the next steps I would say wait til you maximise what you have at the moment, it will be massively improved by remapping what you currently have. That may be enough for you.

If it isnt then there are plenty of turbos and other items that can fulfil your future goals - it depends on what your targets are as to how you will get there.

 

the AVCS heads suits the T better than the H imho.. out spooling the 20g on occasion.

Really?!

When can you get 1 bar and max boost by on a 2.0L with a 321T? Compared to a H?

 

about 150 to 200rpm in it.

 

Thank you to everyone who read my post and replied, can someone now help with the re map, and how much shouldit cost?
