Yes, I have found them (1u) for as low as $300!, and the LS1 for like $3000! It's just hard to deny that. I can just imagine what I could do with the extra $2700. ( Turbo, internals, help pay for my RWD conversion, ya know stuff like that)
The original 1UZ 4.0 litre has proven to be as strong as anything out there to take boost. Too bad it is such a small displacement.
I'm swaping a LQ9((Iron block Ls1)) in mine this summer
Its going to be a challenge i think depending on how hard it will be to mount it in there
and wiring of course, tranny tunnel
sorry but i had an 5.7 litre 225kw LS1 in my commodore and it was utter garbage. Usable powerband was useless, it didnt rev, its used 2 litres of oil per 10,000kms and was very thirsty even plodding around. I would never own one again.
Not worth doing the swap. In relation to the expense of putting in a ls1 why use a heavy luxury car with irs as a drag machine when there are lighter, better suited alternatives. The chevy motor was originally designed in the 1920's and has been re-engineered a few times but never re-designed, compared to a toyota engine that was designed in the late 1980's. Because the basic engine has been around for so long there is a pile of aftermarket pieces for it and yes they can be made to rev. but the longevity of the engine is greatly reduced far more so than with an ohc design. I much prefer the sound of an american v8 at idle and full song but most of my time is spent driving instead of racing so the smoothness of the 1uz wins for me. Just my 2 cents. Can't believe this thread has been going for about 4 yrs!:burnout:
