Possible GB on 500bhp FPGreen Monster Turbos
 

Just concidering this at the moment as my warranty is about to expire. Its mainly dependant on how much interest I get cos I'd want to get at least 10 units to make this viable.

These are even bigger and more powerful than the 20g but with very little difference in spool up. They are easily capable of blowing 500bhp (US "wheel" hp figures quoted in the manufacturers gumph below).

Approximate calculations are coming out around £750-£800 delivered to my house then 10-15 p&p on to you. Going by my Wilwood 6 pot brake GB, delivery time could be anything from 2 weeks to 8 weeks depending on wether it gets stuckin customs.

Here are the pics...

Here is the manufacturers gumph...

In typical Forced Performance, fashion a new breed of high horsepower turbos are now available for the Subaru WRX and STI in bolt on configuration. The “FPGreen” features a 49lb minute compressor and huge TDO6 turbine wheel. The FPGreen typically produces 400-450 WHP with astounding spool up response and efficiency. The term "Green Model" or "Green turbo" are trademark protected terms used to describe this specific combination of turbocharger components which includes our proprietary thrust bearing system. Forced Performance designed, developed and manufactured this unique combination of parts. The term "Green Turbo" is not similar to the term "VF34". You can get a "VF34" anywhere, and they are all the same since IHI makes them. The "Green Model" is different. They are manufactured by Forced Performance Inc. in our 6000 square foot facility in McKinney Texas. Forced Performance Inc. is the sole source for the "Green Model" turbocharger. Nothing beats the original.

The FPGreen’s 7cm ported exhaust housing retains the stock Subaru flange patterns. An internal wastegate is standard on the FPGreen with an adjustable 15psi high pressure actuator and is capable of filling the Subaru motor with over 30 psi of boost if called upon. Install is simple and straightforward, allowing use of existing exhaust and intercooler components. This turbo features a 2.4" compressor housing inlet as standard spec or an optional 3" cover can be selected for those intending to run 3" air inlet tubes such as the Perrin tube.

Like all Forced Performance Mitsubishi race turbos, the FPGreen is fitted with FP’s proprietary severe duty bearing system which increases surface area to deal with the loads of high boost pressure found in racing applications. No other vendor can offer this thrust bearing system. Forced Performance also carries stainless steel high flow oil feed lines to complete your installation.

For those of you that run 3" air inlet tubes for your turbochargers, we can now offer the FPGreen model with the 3" inlet compressor housing. This has shown to significantly reduce lag and deliver more whp by reducing the PR the compressor section must operate at to achieve a given boost pressure. The corresponding reduction in turbine back pressure is the key to this improvement.

Dyno Graphs on this unit can be found here but keep in mind they are Wheel hp figures and US low grade petrol - http://www.pdxtuning.com/sti_dyno.htm

Just let me know if you could be interested. Ta

What about the red one, Danny? :cool:

It was concidered but 500bhp is plenty enough for me ;)

I'm sure it could be added to the GB though as my supplier lists the Red only a littlebit more.

I'd be interested in either tbh...as long as i have the dosh. :D

Hmmmm, :D

what is 450(us) whp in normal UK bhp?
and pump gas in the states isnt measured the same either so its not that low grade.

Found this which might be worth a read for comparisons. If you read the bit about the 20g they comment on the FP Green.

HTH.

The 20g has a 44lb wheel and the green has a 49lb so you can work out the green has approx 10% more capacity over the 20G. It will never make anything like 500 flywheel (never mind wheels) in the uk.
Consider that it runs an 06 turbine wheel which builds in more than 10% more lag and you may not end up with a faster car overall. It will make more than a 20g on a RR though if thats what floats your boat :)

Reasonable turbo for a high torque 2.5 however.

Andy

Andy what would you suggest for a 2ltr STI 7 UK engine? It needs to be as responsive as possible.. What about going twin scroll?

:wonder: :wonder:

Group buy on Andy's 20G's anyone? :D

I've thought about nothing more coming into work today. :lol1:

Danny

I stock the "green" spec turbo too so its not a sales pitch for the 20g.
Just didn't want to see someone buy the wrong turbo based on usa power claims.

Andy

Don't want to pollute this thread too much.....however ;) twin scroll is the way to go IF you want to retain the response of the vf35 and achieve around 360bhp.
If you can sacrifice 300rpm in spool then you can have more power with either an 18 or 20g

Andy

Had anyone fit a green turbo on a 2.5 yet Andy? Or even a full TD06?

What about an uprated custom twin scroll Andy?

Im still on a 2ltr and want it to be super responsive, the lag kinda put me off the 20g :wonder:

No worries, as always I value your input.

I didn't want to mislead people. I was just going by the 30psi quoted in the gumph and adding a "calculated guess" for trans loss to thier claims.

The 20G would would certainly be my choice for a 2.0 road car but if you have a 2.5 and you want the best peak/quater times the green must surely be the way to go?

blimey

What is the lag like on this?

What RPM are we lOOking at for spooling, with say, ported headers, compared to the standard STi turbo?

????????????:wonder:
