i have a t67 i believe with a 8cm exhaust housing and have not been able to find a larger one to suit, you people with td06's do you know the exhast wheel size to compare, mine it 60mm from memory. Im not sure what to do atm as it will spool up nice and early with very little lag but not sure how much it will kill the top end.

Im not sure if the T67 uses the TD06H or the TD06 turbine, or another again. I have often read/seen ppl refer to the TD06-25G as the same turbo as the T67-25G, but there could easily be subtle differences, hence the different designation

What size are you after Clint as i have a 10cm and come the end of the week will know whether i want to go smaller, so may be able to trial fit one anothers and see how they go. I may even like to try the 8cm to see if i make the same top end power but with better response...perhaps telling me that my head, valves (???? i duuno) are more of a restriction then the exhaust housing on an RB20.

i would like a 12cm but a 10 would be ok too, thats why i need to find out if the TD06 has the same exh wheel, the blokes at MTQ said it was bigger than a TD06 and they couldnt find anything suitable in the misubishi range.

My engine is being done on a engine dyno so i dont wont to change it once fitted, so if i cant find something suitable i will just use it, can always add some extra power with Nos for the strip.

i think the 8cm is just another way of saying ar.. type thing.. just find out what a 8cm, 10cm, 12cm is equal to and there is your answer.. 8cm mite be .6 or something??? have a look at the ihi rx6 turbo.. very small exhaust housing but huge comp cover.. spools up at like 2800-3200 on sr20 but still packs enough for 300rwkw+ mite the same deal with your t67 with 8cm housing..

Dotn Apexi use a different convention again?

They typically have a P in front of their housing size referecne, which i think is the A/R in mm^2/mm, where as Garret use in^2/in so a Garret 0.87 equates to about the Apexi P22.

So how that helps me work out the Trust 8, 10, 12, 16 cm^2 housings i dont know ...anybody?

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
