shit eh thats changed, according to that i can fit a 6l engine in my sigma lol

the new v6 is direct injected and a massive cunt to tune... cannot disable vats so you need to use everything out of the VE into it...

much easier to use a non SIDI engine and a PS2000 haltech..

and non-sidi opens up more fi options yeh? it might be wires crossed and the sidi might be able to pop turbos on too, just remember coming across it somewhere. i know there's a kit getting about for VZ model 6's.

1UZFE

Or does it need to be a V6 shitter

[10sec rx7]

forget sidi for any conversion or anything forced induction.. at the moment just wont happen., i spent a bomb getting software written so i can tune them, im the only one in the country that can custom tune them still. they are a good motor but not for a conversion or supercharged..

a supercharged non sidi SV6 will make up to 240rwkw and go quite well, we have even turboed a few and they work great too,

1UZFE

that would be the best option, but OP wanted something holden to keep in the holden.

put lexen badges on it then you can have the 1UZ

Fuck the Gm shit and whack a 2grfe in there.


Look for toysprinter's build thread for tips on how its done.

Ive got some VE SIDI heads that I want to get rid of if anyone wants to buy them?

[irsa76]

Manta eh?
Convert the LP9 2.8 turbo V6 to RWD, wonder if the bits will all fit the Commodore block?

L67, ditch supercharger, add Ecotec intake manifold and GT42.

So these V6s are not the rattly pos the original Buick / Ecotecs are?

You'd be hard pressed to tell the difference unless you rev it out past 5000rpm. I'd just stick with an Ecotec for simplicity and reliability.

would tell mate to get his tune except he's in clownsville

on the balance, that would kill. and not sound too bad at all. and have all the options you'd want.

all depends how far you'd want to go and what your main priorities would be.
