Retrofitting A Factory Intercooler....

[Karma Supra]

What did you need? (apart from cooler and bonnet :P) How much did it cost and was it worth it?

[GT4 BOOSTER]

stats i can find on internet are the intercooler gives an extra 10 bhp over stock 3.0 td .

you'd probably get that extra power upping the turbo boost a bit or doing the washer mod on the wastegate.

To be honest its not about the power, more about the reliability and efficiancy, - and the fact that intercooled ones are worth way more!

I personally think its a bit pikey running a turbo with no intercooler! -even if its only a top mount!
