Boosted 1UZ. Combo suggestions?

[TRB01U]

Hey guys,

Im currently building a twin turbo 1UZ. i was wondering if i could pick the brains of a few to see what your ideals would be on comp, and bore size?

I'm thinking of 20 thou over and 8.5:1 at the moment but i'm open to suggestions or if people have heard of tried and tested combos. i'm searching for about 750HP at the fly.

I'm also thinking of twin borg warner turbos. i've heard great things.

Hi there,
Sounds like a feasable combo to me mate.

I have never built a turbo 1UZ however my build philosophy's revolve around keeping bore thickness/integrity by minimal oversize and obtaining more engine capacity by pushing it in from the outside and hence a 'low' compression ratio is good.

You havn't mentioned cams however I assume you will have that covered with a proper turbo grind?

The borg warner turbos are my current favorite - the one on my celica seems fantastic so I have 4 more of them to go on my next race car...

Good luck with it - including keeping power DOWN to 750HP at the fly!!!

Cheers,
Jason

Question is: what fuel do you plan to run? Seems you could probably get away with a bit more compression if you plan to run a decent fuel.......... even E85

what about a superchargER?
