Thanks tigger.

At the end of the day it's the curve that needs to be looked at, not the final figure.

E85 is cheaper than Pump98 eg; Yagoona United E85 = 139.9 Pump98 = 178.9.

Yes area under the curve is what it's about.

Hi mate, I’m really looking forward to your build. You’ve been a huge advocate for the community and it’s awesome to see that you’ve landed on the IS38 upgrade path. I’ll add a placeholder on the front page for you. All the best with your build, you must be pretty excited...

Thanks mate....

Was Initially going to go with a Littoc 550hp upgrade but changed my mind, will save the extra money the turbo and associated hardware would cost for my 'weekend' car fund.

Update...

Put the IS38 on Tuesday, noticed a few marks on the compressor wheel and slight comp to housing rub before putting it on that I did not notice when it got delivered, we thought the rub was because there was no oil in the turbo. I was pondering if I should install it, the IS20 was already out so decided to install it and see how it went.

Once installed oil run through it and car idling or reeving could not hear any rubbing so thought all good.

First baseline dyno run at 23psi car made 225kw@4 wheels beautiful power curve, then bang!!! and the car stalled!! Restarted the car and huge rattle from the turbo, removed the turbo and exhaust wheel was hanging loose... Luckily it happened on the dyno and not when I was driving the car otherwise might have dropped a bunch of oil down the exhaust and have to find the exhaust wheel in the cat, also could have put bits of metal through the intercooler and into the engine.

Had to put the stock turbo back on. Now in the process of claiming a refund through paypal for the turbo as clearly there was some damage to it before it was sold......

Hunt now begins for a replacement..Have found a few options so IS38 still on the cards.
