Hi all,

I have 2005 Subaru impreza sti ppp widetrack and currently modifying a few things to it. Im

In the near future my Ideas are:-

-RCM designed tubular manifold & venture up-pipe
-RCM 3'' Exhaust System
-Walbro motorsport 255lph fuel pump
-850cc fuel injectors

Do I add a (MD321H turbo or SC38 billet turbo?)

id be well happy with figure between 370 and 400bhp once mapped

Cheers

 

I'd go with the MD and add a decent front mount to the list.

 

You don't mention remapping but I would assume that would be included in the plan.
I think you would be right on the money with those mods. The 321 would probably make a bit more power of the two turbos, but either will do a good job.

 

yes to be mapped after work done etc. What figures should I be expecting with all that done?

I guess without the turbo changed my current one with max out around 350bhp safely?

 

bttt

 

A VF35 will see 330bhp, possibly 340 tops.

TD05 20g is another option for 400bhp on a 2.0

 

im looking for a turbo that wont give too much lag once remapped, a few have said the MD321H is a good option?
