Big one is a Gt3776 and the smaller one is a T25 from a 205 turbo
RE: Too big a Turbo? - declantg - 26-07-2012
MTFU and run them both
RE: Too big a Turbo? - Daniel306 - 26-07-2012
Smaller one is going to be fitted to my dimma turbo, the big one is going on the Td with possibly a Tdo4 beside it, only thing is its twin scroll so making a manifold will be harder, next week il order the stainless and start tacking things together untill it looks right
RE: Too big a Turbo? - declantg - 26-07-2012
Sweet! will be well worth it when done, the GT looks like it could swallow a child
RE: Too big a Turbo? - 4WayDiablo - 26-07-2012
No such h thing as too big :-P

RE: Too big a Turbo? - Anton - 26-07-2012
Yes it's too big lol
RE: Too big a Turbo? - Dave - 26-07-2012
That is too big, you'll need to have some sort of charger/smaller turbo before that... and a T25 wouldnt really be small enough to have that big one on boost before any usable rpm... and if you did, you'de need forged rods to cope with the advance/boost aswell... chronic turbo, and would make for epic amounts of power, just not on an XUD
RE: Too big a Turbo? - Ruan - 27-07-2012
The hotside is what'll stop you spooling that GT37, that's designed for like 7l+ engines...
GT2876... maybe...
RE: Too big a Turbo? - Daniel306 - 27-07-2012
It's for a 7.5 6 cylinder new Holland. I'm sure il find something to fit it to. I was planning to Sc it but it's finding one at the right price. Being twin scroll could I block off the high rpm side and just use the low side. Each port is the same size a td 04.

Dammit, I was gonna say that.
RE: Too big a Turbo? - cpikey316_ - 27-07-2012
Turbo too big???
No, the rest of the engine is too small......
RE: Too big a Turbo? - Ruan - 27-07-2012
You could spool it...
But it's not going to without either another smaller stage turbo... Simply down to the fact the assembly will be SO big...
Or chronic amounts of nitrous to get things going... I've seen 1.9s spool GT42s, but compounded with GT32s...
RE: Too big a Turbo? - Daniel306 - 01-01-2013
So could this turbo work if it run twin? or should i sell it and find something more sensible ?
RE: Too big a Turbo? - Ruan - 01-01-2013
Twin turbo, it would work yeah, but I still think the hotside is too big really given the compressor size...
A GT32 would be a better option IMHO - but that's me...
You're going to need SO much air to blow through the exhaust side to get things moving...
RE: Too big a Turbo? - Chris - 01-01-2013
Isn't the guy with the white one running a gr42 90ish that's twin scroll and he says it boosts by 2.5k?
RE: Too big a Turbo? - Ruan - 01-01-2013
It's not a GT42...
Apparently now it's a Holset HX35...
RE: Too big a Turbo? - Chris - 01-01-2013
Hmmm, in that case bolt it on and find out?
RE: Too big a Turbo? - Piggy - 01-01-2013
too big to exploit the potential.
need mega internals to make it worthwhile.
a modern vnt smaller unit be just as good

Anyone know what this is?
RE: Too big a Turbo? - parrotveasey81 - 01-01-2013
looks like a turbo to me

RE: Too big a Turbo? - cwspellowe - 01-01-2013
f*cking huge! :o
It's strange though, AiResearch turbos normally have the Garrett name stamped in the compressor housing too. And it looks like a T3 style 4-bolt flange.

It's an old garret
RE: Too big a Turbo? - ginge191 - 01-01-2013
lag-tastic!
RE: Too big a Turbo? - cwspellowe - 01-01-2013
Looks like a T3 of some sorts to me, maybe not a super 60 anyway but still mahoosive
RE: Too big a Turbo? - Daniel306 - 01-01-2013
airsearch pat no 3058787 A/R48 4TE88
Thats all the number i can find on it, possibly a T28
RE: Too big a Turbo? - cwspellowe - 01-01-2013
Seems to be a bit of confusion between a T28 and T3 internals. The split wastegate points to Nissan motors though, with the wastegate in the downpipe, something like the 200SX
RE: Too big a Turbo? - Ruan - 01-01-2013
T04E isn't it?
Proper old either way...
