Well my turbo guy is calling it a T38.... same as what he ran on his hillclimb integrale last year but i'm more inclined to call it a t34... it bigger than my t3 super 60... substantially!
The facts.... (compressor side)
compressor Wheel = 71mm exducer and 53mm inducer
compressor wheel has 7 blades
exhaust wheel has 11 blades
compressor housing still has 2.5" inlet
compressor housing has M11 stamped on it whereas old super 60 had M27 on it...

any ideas?

Nick

it basically sounds like a mismatch of a t3/t4 turbo best of both worlds really its not quite a TD04 so it should make decent power around 450bhp and i believe the M11 compressor housing is easier to machine than the M27 to fit a larger compressor wheel i have a 63 in mine and that was a squeeze

I want your new turbo

Well I was aiming for around 375ish with really quick spool... That's why i'm keeping the 48ar exhaust housing!
Saints turbo is rated to around 450 but its bigger than mine as he has 76mm exducer and 57mm inducer...
I'd have thought mine would probably max out around 420ish... But with a 63ar housing??
Can't wait to get it back together now..... Mechanic is dragging his feet, he really doesn't like working on my car!
Might find someone else near by to do it as i'm gettin ithcy feet now!

Any pictures? Its got a TO4B V trim compressor by the sound of it.

I had a very similar turbo on my 8V, it had no lag but surged a little. It wont make great top end with the .48 turbine

No pics at mo matey as i'm surfing the web on my phone lately!
So do you think i'm being unrealistic for thinking sround 370 peak..... There are loads of cossies making this on the 48 housing!?
Glad i've gone this route tho and stuck with the 48 as main priority is minimal lag!

Nick

You'll probably find that most cossies will be running 2 bar of boost to get that figure though.

The 48 housing sounds small compared to the compressor wheel, but I am not that familiar with the T3 / T4's....

T38 is a roller bearing turbo

Yeah i'd seen those..... Deffo not roller bearing tho!
Have to just wait and see what happens on the dyno..

Anyways had some good news on the rebuild front....
Just gotta source some piston rings now and I have all the parts the garage will need and they reckon they could have it done in around 8 hours...... Seems optimstic to me but what do I know hey!
So may have car and start running in within 10 days....
WAHOO!
