putting T03 of RB30ET onto RB20det?

[DriftnR31]

Just purchased an RB20 for my R31 due to the old RB30et giving up the ghost. :ghost:

I figuered that I would be able to bolt the T03 of the old motor onto the RB20 but when i do nothing aligns properly. due to the angle of the rb20 exhaust manifold flange.

I could make some oil n waterlines up to fit but the oil would be flowing through the body of the turbo sideways (horisontal) and I know that this is a no no. and i would also have to rotate the compressor housing.

I rotated the exhaust housing so that when the turbo bolts on the compressor housing is in the right place and the oil is flowing from top to bottom. but now the wastegate actuator and diaphragm dont align and the dump pipe sticks out sideways and will never bolt up to the exhaust.

I thought i could "cut n shut" the dump pipe but this would still not solve the wastegate problem.

I was thinking i could put the rb20 turbo's exhaust housing onto the t03 but am not sure about this as the T03 would have a bigger wheel....

I am hoping someone here could inform me as to wether there is another type of exhaust housing i could use and hopefully point me in a direction of who to speak to about this problem.

I am located in melbourne, who would i call about this?

thanx in advance.

I honestly think it would be less hassles and cheaper in the end to buy a turbo from an Rb25det.

direct bolt on and produces about 10-15rwkw more than stock turbo at same boost level (10psi)

$350 was what I payed for mine about 2 years ago.

they are about the same price these days.

I also think that it would be a better turbo than the 1986 model rb30t turbo.

not to mention in better condition.

also, I was under the impression that the rb30t turbo had it's wastegate flap attached to the dump pipe rather than turbo.

I'm sure this is another thing you would have to over come or just use the stock rb30t dump pipe which is most likely crap.
