Found another number on my turbo, RHF4. Still can't find any information, but I'm starting to think that the VF20 and TD04 might be almost similair..

Hmm, I looked up at a Subaru parts site what a new turbo cost, was cheaper as expected, but looked on Eblag by that part number. Found a reconditioned TD04 for a reasanble price, but they look smaller as expected. Anyone knows how the TD04 - 13 T relates to a VF20? Does a TD04 cranks out more then a VF20?

Anyone here who has experience with the cheap turbo's? These days it's or very expensive, or very cheap. I'm after a bigger turbo (TD04), and Eblag offers a couple of these for $230. I did had a cheap on before, but that was when I started the project, so it suffered abuse by me experimenting and stuff. So it had a bit of play on the shaft. Anyone who has experience over a normal use for a longer period of time, if they make it Thanks

I'm after a TD04 or a VF23....

It's getting fun when you reached the max torque... And that is at a lower rpm then NA

You've got the breaker point ignition I guess, Fit an electronic ignition from a 850, straight fit. do think you need the coils too. Probably cheapr then a Dyna2000, runs well then. The GS1000 loves a 1085 with higher CR, porting the head will do a bit too, can get a nice/flat torque curve. I had Mikuni RS34 on mine, no noticable power increase, but a very good throttle response!! Exhaust is also something you can win some power.

I have something upgraded, at least the salesman said so, but I don't have a clue where I got it from..

Ah, thanks!

Why did you choose for this setup? Because how you have it you have both a long exhaust and intake..

That looks like a mix between blow and suck through..

May I ask a (probably dumb) question? What's exactly a slipper clutch? Is it a clutch without a clutch lever what engages when the revs go up?

I think I had a daft moment...

Huh? How? Sprocket and exhaust are on opposite sides..

Those adapters miss a rim to centre the O-ring.

The holes where the studs go in, are this blind holes, or all the way drilled? If drilled all the way, you need sealant on the studs when you put them in..

The stud might need a bit off sealant on the thread. It might need a new base gasket.

I don't think it will wash the cylinders..

Hmmm.. That's pretty high rpm.. I should have internals what are strong enough, I can go up in HP numbers.. But it's not what I try to achieve, if it's there it's nice.

Probably less heat in the intake too with a big turbo

I'm thinking of taking it, I probably need a bigger intake pipe, that gives it less restrictions in the intake and exhaust, so most likely better running off boost to a higher rpm.. I have no idea how to read those maps..

Gents, I can get my hands on a free gtx3071r turbo, ball bearing, almost new. My mate had it on his Subie, cranking out about 500hp, he got himself something with more output. Now I'm not after big HP numbers, I have the idea that a bigger turbo with less boost might be better then a small turbo with a more boost. I've got an VF20 now, full boost at 4000rpm, but a lot of detonation, I think the detonation is because of the small turbo. But the gtx3071r, would that be too big? I've got 1245cc cylinders on my bike. Thanks

Is it blowing black smoke?

I do notice with my own bike that when I close the throttle the boost pressure goes up, by at least 4/5 psi
