Hi all

I have a coupe with around 300bhp but I would like a bit more.
The currect spec is:

Trim 62 t28 with 360 seal
Fmic
Flea map
Sip
Greddy boost controller
Fuel pump wiring mod
Scorpion cat back

The car goes well and in the high setting boosts to 21psi at 11.5 AFR.

The engine is healthy and sounds good so I would like a bit more out of it, maybe another 30bhp would be nice.

What could I do to get this?

Cheers Rich

Change up to stage 3 hybrid?

Ross

if it's the 62trim compressor wheel you have that's a stage 3 already, the next step up would therefore have to be a gt series turbo like a gt28rs which will allow you to use the bigger 0.64 a/r turbine housing

it will be quite expensive to do this however, i would be asking myself if it's worth the extra expense for another 30bhp

If the exhaust side of the turbo is standard, then it will give a max flow of 300-315bhp.

Send me a PM if you would like to know the best way forward and I'll advise on a number of options.

Flea you have pm..

Change the original downpipe for a 2.75-3 inch, the 16VT one is very restrictive, there for i'm not sure u can reach even 280bhp this way.
You can install better tubular manifold, i changed the original one and boost start now 500rpm earlier for me and much better all scale power.
I hope you changed the original head-gasket for something stronger.

Are you still with the original 384cc injectors?

Hi sorry to hijack your thread but i have the exact same question but only for my 20vt

my current set up is

Stage 3 Hybrid turbo
FMIC
Full 3" Downpipe through to Supersprint backbox
Greddy Spec 2 boost Controller
FC Performance map 1.4 bar
Fuel pump wiring mod
Uprated clutch

im looking to squeeze abit more power out of her but im not willing to pay out for a new turbo yet.

Will uprating the injectors with a new map be a worthwhile investment or will it not make much difference in power epically if I’m going to be sticking with the stage 3 turbo?
will i be able to up the boost anymore than 1.4 or am i now being greedy lol.
