i'd really, really like to swap my LS3 out for a modded Barra turbo...

Andy;107397 wrote Incorrect. I've got the ok to engineer a 5.3LS with a turbo and that came from Vicroads...
The stock LS pcm is very tunable using Hptuners and can easily pass any 1980s emission standards.
With an exhaust and a basic tune the LS will easily output 400hp. For a light car like the 240 400hp will be enough for drifting and the engine and gearbox will be on a holiday.
Plus if you want to sell it it will sell pretty damn quickly.

Which is incorrect?

5.3ls isn't a local ls. It's an American pick up engine. Along with the 4.8

Haven't we covered this in a few threads?
Vicroads has a spreadsheet outlining it.
But your an engineer right? I guess here is the grey area in action.

Rev limit at 5200rpm and it will last for eons

Lol and not make the power it should either.

Even with a 5200rpm limit it will make more than enough power to drift with

An R151 from a 2wd hilux with the 1GR motor is basically the same as a R154 but with a lousy first gear and a fraction of the cost. I paid $600 for mine and have adapted it to mate with a B230. Havent run it yet so don't know what it will be like to live with. Worst case down the track I will save my $ and get an R154 which will slot right in its place.

Also weaker synchros and other accumulated wear from being in a Ute.

Let us know how it goes when it does go in. Wouldn't mind a cheaper gearbox conversion
