Hi all . .

Everyone has their own opinions on what the best way to start tuning one .

So I have a fully standard type r developing 301.9bhp @1.35bar,since then ive added an alkatek ecu, japspeed 3" system, an aps inner wing induction kit and am looking at a decat next.

What would you guys do whilst initially keeping the maf and tmic? What bolt on turbo changes are there?

My ultimate goal for the car is about 375-400 with no meth

Upgrade turbo and injectors to 550cc, should bring you what you looking for.

"what the best way to start tuning one"

From the inside out would be my answer to such an open question. The biggest issue by far is understanding what kind of life the engine has had before you owned it.

I wouldn't bother modding any engine unless I knew the internals were 100%. The crank, rods, pistons, rings and associated bearings are all in spec without excessive wear. Then you should have a good idea of what power the motor is capable of handling.

Th car has had a freshly reconditioned engine from the last owner and he only put 6000 miles on it in 4 years of ownership . . that fact in itself doesnt give away what condition its in though I know.

Martyn at engine tuner did comment that this was one of the best, if not the best, classic hes driven in terms of the way it goes, stops and generally feels

375-400bhp reliably on a classic?
New gearbox, either a 6 speed or something like a scoobyclinic gearset, full engine rebuild and after market ecu, bigger turbo, injectors, uprated internals, the list is endless though you could cheat with 2nd hand parts like a new age STI bottom end but if you are going to do it, you may as well do it right the first time and not twice
Of course it wont be cheap, tuning classics never is, your "safe" (and that safe depends on a lot of factors, most which you may not know unless you open the engine up) limit would be around 330-350bhp.

Not wanting to **** on any bonfires....

I bought mine with a "fresh recon motor" turns out it to be a legacy engine that had been built by the pg tips monkey. Live an learn eh.
