turbo upgrade

[v6tt_828]

hi.. i'm using 6A12tt engine with standard turbo ..
planning to replace / upgrade the stock turbo with something else (greater power ).. any suggestion?? Single? turbo or maintain with twin turbo? if single turbo what turbo is recommended?? for twin turbo ?? any ideas guys?? HeLP

you could try the twins from the 6A13 not sure if its a straight bolt on or not though.

Factory twins - good for mid 12 second passes, around 190kW @ wheels, no more

Legnum turbos aren't a bolt on - I've tried - the bolt pattern isn't shared by anything else at all.

Twin upgrades - twin TD04 13G's wake up around 4500rpm approx, but very very tight for room.

Single upgrades - I've seen a T04 single, woke up around 5500rpm. Evo 3 spec TD05H 16G woke up around 3500-4000 and made 160kW @ wheels on 8psi, personally I've just gotten an upgrade running with an evo 4 spec TD05H, full boost by approx 4500rpm gear dependant, going on the dyno tomorrow night but its wuicker on 10psi than the twins were on 18.

how are you going to get the mivec to kick in?

how are you going to get the mivec to kick in?

mivec controller and utilising the standard mivec actuation components?

[Eurospec]

As long as you have the oil control valves, and the oil ways are there between head and block, then any kind of rpm based switching device will do the job.

Just remember when you map it, obviously it will need more fuel as it comes up on the big cam.

Whats the piston clearance like when the big cam is operative?

Cheers,

Ben.

I don't have my turbos anymore ( I think someone turbocharged a lawnmower or blender with them), but a mate of mine has 3 engines worth of turbos and manifolds sitting gathering dust. If you want them sing out, but shipping to england might sting you a bit.

As for the turbo upgrade - how much power do you want? Anything at all you do is going to need custom manifolds made, so may as well pick a pair of turbos that are cheap and easy to find, and will make the power you want.
