im looking a putting a turbo into my forged 2.0 engine, i idealy want to run 450, bhp and was wanting to no what others are running and what figures you have and how they feel to drive , dont want anything loo laggy, but at the same time want as close to 450 as possible,

 

i would be interested to know as well a lot of people are using the md series turbo so an alternative would be nice
martin

 

Look no further than the S206 then Martin, has made 450-505hp on my own stroker during the development phases and another 1 made 450+ yesterday on a similar setup.
Feel free to ring and I will be happy to tell you all about it.

 

who makes this turbo, price and what sort of figures has it produced with reguards to spool

 

Turbo Technics make the turbo and it available exclusively through Enginetuner.
Price is £995 + vat for the turbo oil and water lines delivered FOC, we can also supply a custom stainless downpipe with or without cat.
It fits on the stock uppipe and is perfectly suited to those with any intercooler which sends the hot side to the drivers wing shortening the pipe run removing the ugly 180 degree bend over the turbo. It requires a 3 inch intake hose similar to other hybrids on the market and we would recommend RCM or similar manifold risers.
I have included a couple of pics of one installed on my own car and a couple of dyno graphs from the development phases.
My own version is a 2.1 and spools very well making full boost at 3700rpm in 4th and 3500rpm in 5th, it certainly won't be worse on a 2 litre than a full fat GT30.













Feel free to ring for a chat should this suit your requirements.

 

Actually, I believe the thread was about the AFP30H which is a garret turbo from Andy Forrest Performance (based on a gt30r).

Here's some more info over at Andy's site: AndyForrestPerformance

 

Personally I think a GT30R would be a little laggy on a 2 litre, bear in mind you would also need rotated up and down pipes, and a external wastegate. So you need to weigh up the pros and cons against a standard position turbo.

Banny

 

good point

 

Just giving the OP alternatives to what could be an unresponsive setup which will cost a lot more with twisted up and downpipes, external wastegate and the like !

 

Sorry, my post came across all bitchy - not intended! Must read posts before hitting "submit"

Anyway, now the OP can have a look at both the S206 and the AFP30H

 

martynj,

is your 2.1 car a classic ?

what heads are you using ?

thanks

 

Yes it is a Classic Jap spec WRX, we are using the stock heads and cams with some flow work carried out in house with stock valves.

 

thats some good power, i'm just wondering what that would be like on mine 2.1 with sti v4 heads

 

Martyn - thats impressive given you're not running VVT heads!

 

cheers for the replys guys, some good info, Marty cheers for all the info, how would these turbos compair to the likes of the old td05-20g

 

20g on a 2.0 would be really laggy but cheap, i'm sure they are better suited to the 2.5 etc

 

so compaired to a md321 h or t turbo they are more laggy. but as u say half the price

 

I wouldn't call it super laggy... I get full boost in third by 3500-3600rpm (andy forrest td05-20g). Seems pretty good for a near 400bhp turbo

 

20G aint laggy at all i got full boost on the road at 3700 in the 3rd gear with out meth and every time i changed gear it always rpm always dropped at the sweet spot. its more a 370bhp to 420bhp turbo if you add meth on a sti, if you want 450 or more then i think the S206 is the route to go. il be changing my 20G for an S206 within the next few weeks
