I suspect you have a fair chunk of torque to go with "only" 380 ish bhp,

Guessing well over 400Ftlbs 420 ish even

20g was spooling at 2800 and dropping like a stone too until I discovered an inlet pipe restriction... now it holds boost all the way. Can only assume this was the problem with the previous setup too. My point being let's not be too quick to blame the tubro. Chinese or not.

Considering that's what the whole topic is about then why you being so evasive about it?

Na my car weighs 1400 on the button with half tank of fuel and the spare wheel etc. I am 95kg

surely not with that torque ?

thought it was a moded audi quatro box?

which is a relavvant point to be fair, makes drag times a bit irrelevant cos the ratios will massively affect the times

Massively? I ran almost the same times with a change from diesel ratios to petrol ones, seems that ratios don't really change your time in my experience

well people like Andy F, Mikee and others who do a darn sight more than you would argue different. Mikee for example won't switch to a 6 speed for that very reason (although added weight is a factor as well).

Transmission losses would be different to any other subaru as well,

Nice car making great numbers but cant compare to most as yours is kind of unicorn build,

Out of interest was it much more expensive than a 6 speed swap or just time consuming ?

Anyway we digress, regardless of ratios the turbo makes the power

Just get it on a dyno and then we'll know.

(dyno dynamics and shoot44 mode lol)

I'd say the Quattro box has more transmission losses than the wrx box due to the wider gears and bigger bearings (it's all double the size).
Cost is now about the same and has been very time consuming. Probably wouldn't do it next time.
Ratios are now nice and if it breaks or fails I can replace it for £250.

a 1/4 time shows nothing about drive ability or spool characteristics ?

Yes its fast

Butt dyno/drag strip isnt a way to compare turbo's.

Of course it does, .1 second lagg every gear change would make me .4 seconds slower over the 1/4. Spool is a everything on a manual H box drag car, not running flat shift.

Originally Posted by SmurfyBhoy

Spool better make more boost and hold for longer, plenty of reasons why.

Last longer when doing it,

May not be cost effective but will always perform better,

Yet your making claims about the kinugawa turbo being good with nothing to reference it against.

How do you know your setup would not spool better and harder on a different turbo?

You will struggle to beat 1.6 bar by 2800 lol, if you can I'm not really needing it lol

Originally Posted by SmurfyBhoy

Not personally but contacted various places that rebuild turbos and was told shaft and bearing quality on majority of ebay turbos was very poor to say the least, that and faulty actuators,

Decided against it,

Got my sc42 which has been upgraded further still by owen developments which i know has been checked and balanced by a professional instead of mass produced to huge tolerances in a chinese sweat shop
