Hi guys,

I have been researching turbos for some time, and was hoping to get some outside advise for my setup.

The problem i have is finding the right balance of spool time, and power displacement. With an idea of 470-550bhp and the quickest spool time possible, any suggestions would be great.

I have been looking at a Turbonetics T-58 with a 0.58 A/R housing.

Does any one have any recommendations or knowledge about these, or alternate turbo setups?

The other issue i will also have is boost levels, as i will be running stock internals i would like to keep them to a fairly safe level.

Thanks

Stock internals will handle 25-30 psi . It's all in the tune . Sounds like a good turbo . The 3076r with .8 rear will make 400rwhp with decent spooling . Also look into precision turbos as well

Thanks Daniel,

I will check out precision turbos,

I have also seen some twin TD-05/TD-06 setups, but i have been unable to really find anything as far as getting the parts to make it happen, im thinking its all custom fab.

Can anyone also recommend good places to look for building this kind of setup?

Don't bother with a twin setup , way too laggy . Single is the way to go , unless you want to retain the factory look and high flow the twins . But won't reach 450+ rwhp

Thanks Daniel, that is awesome to know about the standard boost levels.

Im building the car for rally driving. So i need around those power figures with early spool and really usable power (No drifting for me).

At the moment, im just trying to find the best turbo for my application i have checked out Precision Turbos, and the TA55 CEA looks like a good competitor.

Any other recommendations?

Still not sure if they are available, but the Borgwarner EFR 7670 with the TS 0.92 internal wastegate looks great on paper..

Still relatively untested though.. I did up a matchbot plot and followed the guide and it predicted 5PSI @ 2000rpm

Hi Tai,

yea, Ive been looking at that model as well.

Defiantly a good contender, i was just unsure of its performance running 15-20psi?

Thanks for the input, really appreciate it.
