I've a 300zx TT Auto, and I've got a big pb to choose my new turbos.

 

I would like to buy JWT Sport 500 or JWT Sport 600, they exist in 2 version A/R 54 or A/R 63.

 

I want to keep at maximum the comportement of the engine but with approx. 500 rwhp (perhaps it's utopic !!!), but not a big lag.

 

Perhaps SPORT 600 A/R 54 are not too bad.

 

Thanks,

Yann.

you'll need something bigger than the JWT 500's. 500rwhp is a lot and you'll need a load of supporting mods to get that far.

 

I'd spend some time searching twinturbo.net, study dyno graphs and remember that a lot of their peak number dyno's are achieved with race gas so they can wind up the boost and advance the timing more than you could with normal fuel.
