to be honest if you just after a little bit more perfomance nothing stupied, agetting your oem manifold flowed is decent upgrade depending how restrictive the oem is .

de-cat is another one

and am sure your stock turbo will take a bit more boost .

you dont realy need to go external wastegate unless u going over 400bhp imo aint realy till you get to that figure you start getting boost creep..

i am a big belive in holset turbos , had a few now , once you figure out how to work the power etc out that they will flow pretty simple .

holset are just deisel turbos , so for example a qouted 500bhp holset will probley flow in the region of about 700on a petrol car .

i have 2 here from a scania truck which are holset turbos and qaulity is as good as uswell

Already decatted, and the restrictive baffled backbox has been replaced by another straight through perforated centre box, with the old tip welded back on.
So the exhaust is breathing well

Turbo boost will go from ~ 1bar > 1.4bar

Power has gone from 90bhp > 150-160bhp

Turbo is GT15/K03 type...

If I could almost do what VAG did with the K03, and go to a K03s or K04 sort of size for that bit more power, but with the same housing, that would be perfect really

Still loads of options, I have no idea exactly what I want/need at this point, it's just nice to have a resident caster on PH who I can pester if and when the time comes

pm me a ruff idea what sort of price looking at so can have a think , to fit a ls7 engine with conection for turbo and to run external wategate of it

thanks

Something like this, these are for ls7 or any lsx for that matter? The Tial is on the underside.



Fit the turbo's onto the front via an elbow or adaptor.

any chance of some basic mesurments need 2 decent size turbos to be able to fit , and as its not going in the chassis it was designed for , could get tight .

i take it there cast or have i got it wrong lol would much prefer cast saves the cracks but they look very sturdy , when you hanging 2 dirty bg turbos on them there bound to break .

you got any pics by any chance of them fitted to a car just so can get ruff gauge where they will sit as new chassis is much narrower

many thanks and sorry to be pain in arse lol

The manifolds are 3" wide from the head face. As for the turbo mount it can be at any angle from sideways on the engine to forwards of the engine. Flanges are for t28 to t37. Yes, they are castings, not welded.

Wow, they look like just the kinda people I need to be talking to, engineering out the OEM housings to get the best from them etc...

I will have a few spares kicking around so can send one down for them to have a play if they think there is much to have from one, then however I look at it, it's a nice new recon turbo anyway which is probably better than my 8 year old 100,000 mile one by now
