Help with TD06 exhaust housing size/fitment

[Nismo_Boy]

I picked up an incomplete Td06 Turbo with out the exhaust housing. I don’t have much info on the turbo, other then the numbers on the compressor plate. Obviously the turbo used to be internal gate. But I’m looking at fitting a external gate rear housing.

First off, does any one have some info on this turbo? What size is it, with a correct rear housing matched up, around how much power am I looking on an Rb20det, with basic support mods? (Exhaust/cooler/fuel and Dr drift ecu)

Second, would the exhaust housing from a TD06 of similar size that use’s ex/gate fit? Or will have too get the correct housing meant for this turbo, then convert to external style?

The compressor wheel is around 2-¼ inch’s wide, and the rear would be around the 3inch.

Any help would be great.

I have a TD06-20G, well thats what my blue ID plate says. As i understand it the black ID Plates are the older style of Trust turbos...so what that means in the way of flow i have no idea.

If its going on an RB20 id suggest you stick with an 8cm internal wastegate housing. Im currently using a 10cm housing on my RB20, but will be shortly changing to the 8cm to see the difference in response / power etc.

Looking at that turbo your turbine looks very similar to mine. Id say the same but im going on memory, adn it makes sense that it looks the same as the TD06 name refers to the turbine size.

Though thing to remember is that there is a TD06 turbine, then a TD06s, TD06SH and all are slightly different.

Your compressor wheels looks different to mine...smaller. But that could be the fact that my compressor cover has a 80mm inlet. But i would hazard a GUESS (its probably an un-informed guess:)) that the compressor size is around the 18g area.

At the moment i make 16 psi at about 4600-4700rpm and about 222rwkws with the 10cm housing.

If you go external wastegate you will need a trust manifold as the external gate housings use the 3 bolt Mitsubishie flanges. You can get internal gate housing sthat uise the T3 flange meaning you can bolt it to the std housing. Which in my eyes, dont waste your money on extrernal gate and Trust manifold for the 220-240rwkws you will make.

If you want to go cracy, see if you can pick up a crapped out T67 or TD06-25G. Then use the compressor wheel and compressor cover on your TD06. Then on the exhaust side stick with your current turbine and use an 8cm external gate housing. Be a pretty responise 450-500hp turbo on the cheap and is effectively a hi-flow of what you have.

From what i have read on US sites the TD06 range of turbines are the pick for good power balanced with good response. Of late the smaller GT30 turbines have been recognised to offer similar flow but use better aerodynamics to get more punch and airflow from their smaller size.

Well thats my thinking. Hope it helps

Thanks for your input Roy. Unfortunately I don't even have the stock manifold, its a pretty bare motor, thus thinking of just going ex/gate and getting a shmicko manifold, but as you said may be pointless if only getting the 220rwkw mark.

What series internal rear housing would you recommend that'll fit on this turbo, and that'll fit onto the T3 flange manifolds?

is that a 3" inlet?

i had a TD06-19c on my rb20... made 270hp @5000rpm @ 15psi with a boost leak.. (10psi @ 5500rpm

that was using the 8cm2 exh housing... i would opt for the 8cm2 housing on an rb20... it'll hae a bit of lag and a nice punch as it comes on boost, i imagine the 10cm2 would be rather laggy.. mine was modded for internal wastegate... i bought it from WHITE 32

Dave, Just a guess-a-ment the inlet was 2 1/4 - 2 1/2' in size. I dont have anything to get a correct size for the time being.

Think I'll go for the 8cm size, Don't wan't a lag monster that'll only be good down a straight line
