Default 351 BHP from standard 2002 STI

As in title just bought a totally standard 2002 STI & would like it to run around 350 BHP. Before I take it to jolly green monster for remap, am I right in thinking I'll only need 1) fuel pump (warlbro 255)
2) De-cat 3" or sports cat
Also I've got a de-cat down pipe & full 3" exhaust off a classic in my garage - will that fit??

The hangers on the back box are different I think but apart from that the exhaust will fit.

You should see somewhere around 330bhp, you might want to add a 3 port boost solenoid to your list.

But i'd speak to simon if I were you then you'll get a better idea of what to expect and he'll have an idea exactly what it is your after re drivability.

I'd go with your other threads and 350 as a target, 351 is a bit optimistic IMO

350 on a vf35 is possible, but dont expect it, 330 is prob nearer the mark, anythign mroe is a bonus.

to get a higher figure I've seen the results of some mappers go too aggressive with timing and cause det without thinking about the consiquences.

You'll want to get the 35 ported to stop the boost creep, also will help get you up in better bhp figures and more safely.

No proper mappers go around causing det without thinking of the consequences
Yes, there are a band of so called (Professional) mappers running around mapping peoples Imprezas with little or no engineering background and certainly no understanding of how the OEM ecu works.
I was subjected to one of these maps just the other day, shocking

In the right hands and on the right supporting modifications, the VF35 is plenty capable of 350bhp and safely too.
