what can i do to my coop to try and reach 300bhp , if im not wrong the gt28rs is for he 20vT wright?

you would have to get a custom manifold to fit a gt28rs!

i think a Integrale EVO1 turbo can get you to 300, or a cosworth turbo! I'm sure somebody else will be able to confirm soon though!

heheh thanks got to have 300 bhp to beat my neighbour wich has just bought himself a porsche carrera year 2002

what mods have you got at the moment?

so far im waiting to get the evo chip

thanks for the link

Gt28rs is available for the 16vt I'm considering one in a few month.I'm also aiming for 300+bhp although I shouldn't be too far off now.

thats because you have a tubilar manifold though?

Available in a T3 fitment from ATP

3" exhaust, fmic, evo chip, higher fuel pressure ( about 3.2-3.4bar ) t-3 60trim, or bigger turbo. boost about 1.2-1.3bar, thats it. after 330-340hp ( 1.4bar ) you run out of your injectors, and other stuff. and thats not with the 60trim turbo, wich is good only about -320maxhp, I guess.

wouldnt a hybird t3 reach 300bhp?

when I got my T3super60 i think i was told the max will probably be about 300bhp

yea max power is not really what you want from a turbo , using any turbo at high boost cant be as good as a lower boosted bigger turbo . i maybe wrong

as I sead t-3 60 trim or bigger turbo. but thats the smallest you can get those numbers. of course smart tuner wont use as small as bossible. for +300hp I would look about 350hp flow capasity turbo.

with 1.4 bar you should get around 320hp with t-3 super 60 thats about max

Thats in an ideal world, i see from the map the T3 super 60 at 1.4bar should flow 30lbs/min (300bhp at the fly) but I doubt you will get that

I could be proved wrong but I have a larger wheel than that and I am struggling to make 300bhp. espically on the .48 T3 exhaust turbine.

If you have a money a GT series would likely be a good buy, otherwise the T04 family compressor wheels would likely be required.

Personally my most recent plan is a T04e "super " 50 tirm, not the regular 50trim (the super is different)

however I am a bit worried the T04E hat won't clear the gearbox - I have run a T04b hat in the past, and currently do without problem. The T04b wheels will get you to 300bhp -that is basically a cosworth wheel but they are not a great wheel as far as surge goes at low RPM/high boost areas,

The GT series are more forgiving for surge, but of course more $$$

how big compressor ? what size turbine ? I have reach 325hp with 1.4 bar original head. ok I were also using bigger turbo. with headwork and t-3 super 60 I believe it can be done.

about the gearbox I send you some photo soon Saint... wait a moment.

With head work, I agree you could get there JTM, but I didn't see headwork mentioned earlier and thats alot of $$$.

I used to run the T04b s trim but now have a HKS wheel GT2535 54mm inducer/69mm exducer but something is restrictive and I think it is the head. Hence why I think 300bhp on the T3 super 60 would be a push

CRGracing - if you want 300bhp on a smaller turbo I think you will need headwork, otherwise something bigger is required I think

are you still using standard cams ? because chancing those are the key to a hole new world the head is quite good.
when I did my RR they sead i could get 50+ hp more just using non turbo cams. ( and its true ) .

thanks for all the tips,
but in the weeks im probably going to fit the evocars chip
the car hasnt been modified do i have to reinforce the engine or is it ok standard?
eldinho thanks for the link as i reading it i need ecu chip plus exhaust plus front mount intercooler blow offvalve fuel pump upgrade with their respective controllers. with all this ive red that ill get about 250hp wich is ok to start off with but do i have to change rods, pistons....etc?

last knight i was bored soy i went down to my garage and took the exhaust off cut the silencers off and added to straight pipes were the silencers where what do you people think? the catalitic converter do i eliminate it eswel ?

we have measured standard car ( 155q4 ) just using 3" exhaust ( first 90 degree standard ) 220hp with 0.7bar. so chancing exhaust is one of the first mods.you should do. that was with standard chip too.

but did you have to reinforce the engine? new rods, or new pistons.... etc or not nesesary?

pistons are good.they are a bit heavy, thats all. but if going over 7000rpm often,and +400hp you should replace them. they will work fine, if fuelling is ok. and rods are good too etc..no need to chance, with little mods.

1. Remove engine
2. Fit 20VT engine
3. FMIC, GT28RS, Gtech, UNICHIP, SIP, Boost Controller, 3" Exhaust.

= 300 BHP +

really thats what i should do gouki but i would like to keep y engine. to start of with i only have money to put in 250 hp because with 250hp its not nesesary to do any mods i think.

That seems like a much better target!
