Question For Turbo Geeks

[Roy]

I currently have a TD06-20G, and looking at US websites there are plenty of places that put Garret wheels on the Mitsubishi turbos. So considering the 20G does ok to flow 260rwkws odd on an RB20, are they any Garret wheels the same size, possibly a little larger that will flow a bit more then the 20G?

Happy to go a bit larger as i understand the next Mitsu wheel is the 25G that runs a bigger shaft so cant be used to hi flow my turbo. Maybe its time to just throw the larger 10cm housing back on or fo the T67? I think i am pegged at my curent power level because of back pressure from the tiny 8cm housing

Anyone know of back to back results going from TD06-20G to T67-25G on an RB20, SR20 etc?

i know rotormaster (melb) has played with mixing compressor wheels, but as for turbine wheels im not sure, ive asked the question and so far they all reckon its to dear to machine up the shafts etc... and ust try sell you a turbo

the t67 on the rb20 is pretty big (vs response) what is your power goal?

I dont mind the lag, i have something to counter that, i am just looking for a bit more grunt hopefully around the 285-295rwkws.

I have thought about just going to the 10cm housing and throwing some baby cams in the RB20 , as previously there is some thinking that the cams didnt work too well in my engine because of the back pressure from the little 8cm housing. SO perhaps cams and the 10cm housing will be enough to beef up the power band.

Trent, do you happen to have a 10cm housing around as i think my friend sold my old one i swapped with him.

nah sorry, none laying around

should have bought legend01's old set up.

Busy today Roy but will sniff around the compressor situ .

I don't suppose you have pics of your turbo you could PM me ?

I think Trust may have speced a few specials but need to do some searching .

An American site called Melett has some Mitsy turbo specs like shaft dimensions .

Also GT pumps here in Aus advertise that they do Mitsy mods as well . Early Evos , pre Evo 4 , had normal rotation turbos so it may be interesting to see what they did with those .

Later , cheers A .

I believe the classic famous FPGreen turbo is a 50trim T04E compressor wheel mated to a Mitsi hotside - they flow a bit better than the 20G and by all accounts have a really good power delivery. I wouldn't expect a night and day difference but maybe another 20kw or so wouldn't be out of the question.... its a bit hard to tell for sure, but they certainly seem to be able to make cars go well.

*cough* needs more displacement *cough*

would the TD06 make 300kw with an rb30det?

[Roy]

I cant see a TD06 making 300rwkws unless it has a rotary sized exhaust housing, even then it is a big ask. I know the 10cm housing on my car wasnt great, but my current tuner is a wizard and is real good at somehow getting my car do stuff it shouldnt

I just need to start driving the thing again, all this tinkering rubbish goes away once you are back driving

All these hand feed sessions people have about ho good 6Boost manifolds are then perhaps that is worth giving a try to see if they are any better then the Greddy ones? If it does really help spool then go back to the 10cm and see if i can get away with some baby cams

T67-25Gs make some big power...
