I bought this kit for my r33 and found out it doesnt fit rb25 engines as there is not enough clearance for the turbo as rb25 sits lower than rb20, so this kit is designed for rb20 engine...

This is previous thread:

HKS Cast Manifold for RB20/25 forsale along with a BRAND NEW unused HKS 40mm Wastegate. Both items are genuine and not those knock off cheapies.

The manifold has a T3 flange and has the wastegate outlet ontop of the central collector. Arguably one of the best cast manifolds available on the market for the RB series of motors. The wastegate is 40mm and is brand new with all gaskets and mounting flanges. There is also brand new stainless allen key head bolts included for mounting this to the manifold. A fantastic combination and its a regrettable sale.

Wastegate: http://www.sido-takushi.com/mods/hks_wastegate/

Looking for $900 plus post for the lot.

Im sure even the std size turbo would fit, you would just need to rotate the housings to suit the low mount (as opposed to side mount). Cordiapower got it looked at by a workshop but Ive got pics of this type of mani on 25s... so I just dunno whats going on!

    • Just be warned that that turbo will not be a direct re-fit to the car. The exhaust housing is, of course, in the same place. It has to be - it's bolted to the exhaust manifold. So the dump will fit up. But the centre housing is not as long, so the comp housing will move backwards. This will affect both the turbo inlet and the outlet. There is fab work that needs to be done. Yes. it has one, it should have one. Paper gasket.
    • I only recently purchased the vehicle, it came with the flex setup but the current tune is e85 only, which is why im wanting to get the tune redone to enable a mixture.  First i need to get the exhaust redone tho. I was thinking of getting a varex muffler but it sems they dont fit well in the 33 (hang low because of the valve mechanism which sticks out on top) and generally dont sound good. So that leaves me with redoing the entire exhaust (more resonators and mufflers) so its not a menace when i come and go from home, and then have the aes dump valve somewhere along the line to really open it up. I was thinking of having it before the cat but after seeing how insanely loud it will be (on a vl turbo) im thinking of putting it more towards the rear of the car, after one of the resonators. 
    • At this point I'm just 'hoping' it's the turbo seals. I did speak to someone who said it's normal for these turbos to have a bit of axial play? Not gonna lie I've never checked a turbo for axial play before but you could hear it tapping a bit as I moved it back and forth. Surely that's too much? My theory is (could be completely wrong), bad axial play, worn bearings, bad seals, oil into dump/compressor side, burns in exhaust = blue smoke. On a timing belt related note, my crank pulley was missing that front plate that sits in front of the timing belt. It's that metal round plate. It did have the rear one, and the woodruff keys are in the crank which was nice. Can anyone confirm if the NEO det engine has a front plate, im sure it would to protect the front of the timing belt or something. Water pumps...the pump I got was an NPW (yes grill me if I should've got a genuine one lol). It has a smooth mating surface, kit came with a pretty pathetic looking paper gasket. Do I need to use any RTV or just trust the gasket will work because its a smooth mating surface? Cheers legends have a good Easter break!
    • Cheers man, I thought the same.   Bit of an update on it all. It was definitely blue smoke, not grey after all. It didn't really smell oily but it was blue after all. Also puffing just the smallest amount on idle with no throttle.   I ended up pulling the intake and exhaust off and there was around 3mm of axial play on the turbo shaft. So I figured we'll that's buggered and sent it off to get hi-flowed at hypergear. Haven't got it back yet.   I haven't compression tested it yet. Had a look in the cylinder and cylinder 1 spark plug, looked a bit sooty but not oily. Then I've just started doing my timing belt because it's age is unknown.
    • In that case it is probably stock. It lives in the navigator side footwell behind the plastic trim just in front of the a pillar.
