This is what i found out about my turbo from charile at evergreen From what I can see...it looks like Stage 5 Turbine...but surprised to see it looks like a V2 Trim T04B series....having 16 blades high low combined ..

So this turbo good for 400wheel.

So is the gt35r the best turbo for 400whp, I know that there are bolt on options but it seems a bit weird to spend the same money on what is reportedly old technology?!

thanks

The all-out best turbo for 400rwhp would probably be the GT30r, IMO. There are a couple of Holset variants that would be a very close second, and quite a bit less expensive. (both of those turbos are not strictly bolt-in)

The best bolt-in option for the 2.5L would be the LR S53, w/ stage 5 turbine wheel, again IMO.

Lightningmcnulty

What does not strictly bolt on mean, are we talking new exhaust flanges or just oil line issues?

what are the holset numbers.

Thanks Josh

everything..
- up pipe
- down pipe
- water pipes
- oil drain flange
- oil inlet

they all need to be modded or custom made

look at my build thread

MooreBoost

already on it..

Lightningmcnulty

Got it! sounds like a job for front range fab!

Lightningmcnulty

Looking around it seems as though you can buy the flanges and then mate them to the exhaust pipes?!

blown 944

definately not big enough for y0ur goals

Dam it i take it this turbo.is a mid 300whp turbo bc thats what i habe now ...can i use the housing bc charlie said.he can change turbine wheel ect. If so what wheels and ect.

Borg Warner S256?

well it's a little tricky to explain becase some of the wheels are named the same even though thet are to4b vs to4e.

The B housings use a 71mm exduder and pretty small inducers. I have built about every configuration in the B family and IMO none of them flow enough on the compressor side.

The stage 5 turbine wheel is good enough, but you may want to see if he can install a 50,57trim or a 60 trim (76mm exducer variety, to4e wheels)

It would possibly require a to4e backing plate and housing along with the wheels. The center section and turbine side wil all work. Or he may have a machining solution.

It's been a few years since I've messed with the to4b's but I did try them all from h,s-v trim.

Not that easy.. the pipes don't meet the turbos inlet and outlet.

Lightningmcnulty

got it, seems like for the most part its easier to buy a bolt on but there is more choice and possibly better price with some extra work involved.

I need to get a tig welder and get some practise in!!
