Any one ?

 

what power is it making now? its prob making it peak power already. they make around 340 -350 bhp on a good one. beyond that its turbo upgrade time.

 

360hp at the moment, but i dont know what is the block limit , dont want to mess up all. I was thinking about adding biger turbo.

 

Im thinking to go for APS SR40. Max output 440 bhp. But i dont know the max that block can handle. Any one have them installed ?

 

The Garrett Claming that with GT35R i can push my block to 600+ bhp, any one have them installed in 2.0 blocks ?

 

Some info

 

Some more

 

youll need a rotated setup to fit a gt35. rcm do a decent stock location turbo . do some research theres lots out there. over 400hp you should be looking at uprating your gearbox/clutch to handle the power. same for your internals. forged internals is a must for over 400hp too. you say larger injectors - what size? youll need 740+

if any of this is wrong guys feel free to correct me .

 

I have smaller, but i will use 850 injectors for future undates. The problem is that im in Germany at the moment, in here no speed limit and i cant outrun 6.3 AMG, RS6 and so one. So my target is smoke them all in Autobans

 

But i will hate my self if i will lose the sound that i have at the moment, all will be good if its will be better

 

any one ?

 

im starting to hate this forum.

 

Where are you at now with your power requirement... Do you want c.400 or a lot more?

There are plenty of std pos bolt on 400+ turbos out there to choose from. You'll only lose the burble if you change the headers to equal (or near equal) length types... If that's what you're asking?

 

I want to install GT35R ill try to push 600+

 

Full engine build, twin plate clutch, not sure what gearbox you have but it will need to be strong, supporting mods on the cards then.

 

Im now checking how much i will need to invest in this, plus its damaged
