Hi there,
just wanted to know a few things,
-how much mileage has the turbo done and what car were you using it on
-what kind of times did this turbo give you
-What figures was it pushing out, torque, hp, and at what boost?
-what supporting mods did you have on the car?

cheerz,

suhail

I have only done about 1000m with it i brought it from Tim W who i believe used it for about 30000m it was checked and ballanced by turbo dynamics before i recieved it.I had it on a RB5 with gruppe s headers fuel pump and reg full decat and a tec 3 mapped a 1.2bar and it ran 306bhp and 270lbft Tim W had a few more mods and his ran over 340bhp at 1.35bar it is good for 350bhp with the right setup.I believe Tim ran under 13 seconds with it.

Thanks mate,
to be honest i thought it would give around 315 lbft of torque or theres bouts, i saw another guy running a VF22 hybrid MD19... something i'm not too sure what and it had great torque, was looking for something in that range, thanks for the reply anyways

matieboy

you could get that torque easily with running more boost it will run reliably at 1.4bar i only had it mapped at 1.2 because i had a dodgy lambda.I never bothered getting it remapped to its full potentail.

An MD304 is a rather nice hybrid turbo which started life as a VF22, the largest IHI turbo fitted to the classic Impreza as standard. In this form the VF22 compessor housing was retained but slightly enlarged, a considerably larger and stronger compressor wheel replaced the notoriously troublesome VF22 wheel, and the P20 exhaust housing was replaced by a smaller P18 housing (off the VF28) which had been modified to feature an enlarged wastegate button. My Turbo was also fitted with a 1 bar wastegate actuator which also features adjustable pre-load.

It was intended to be a quick spooling and reacting 350 brake turbo

On my car I get 1 bar of boost from around 2800 rpm, and my 1.35bar peak from 3100 which it will easily hold to the red-line. The perfomance of this turbo is best described as stunning for such low boost levels.

If competantly mapped on a UK model Turbo with an FMIC, 440cc injectors, a tubular exhaust manifold and 3 inch exhaust system the car performs very well indeed (after it's initial map on my car - a slappy MY98 UK Turbo - we saw 344 brake and 308lb/ft of torque with only 1.25 bar) as the quarter times and top speed runs that both Steven Darley and I acheived at Scooby Shootout last year show.

It's best described as having all the low end pull of a heavilly modified TD04 engined car which at around 4500rpm just takes off into a different league!

I'll certainly miss it's performance, and the only way my new build would compete is with the extra cc I'll be running

The turbo was built up from a brand new VF22, and a new P18 exhaust housing, so it was a completely new turbo when it went on my car approximately 30k miles ago. As I've already mentioned I'll be getting it checked out by TD to ensure that it is as good as new when I sell it on.
