Real pleasure working on this and glad its all running sweet now - so much fun just mucking around in it, pretty tempted to build one myself now! Keep me updated with how it goes!

Our 3.1 Irmsher 5spd LWB (not efi version) is still going strong at 270+k's(had it since 20km). For the last 150k of that with its been modified as as I setup a front mounted intercooler setup, top mounted air intake, removed EGR, modified inlet and 16psi+. I have towed some stupidly heavy loads ...

Sounds very cool! I like the idea of the BOV dumping into the airbox. How long did the turbo last like that?

Will be running a 3inch exhaust this time around to free things up a bit.

Thanks for the reply.

I have heard they are better turbos for reliability but its hard to find turbo maps for them to compare flow. Kinda had in mind a big step up rather than putting something similar on. Got a few leads - just need to compare compressor wheel sizes

Hey guys, I'm new to the forum so bear with me. We've got a 91 Bighorn Irmsher that we've had for years and years. Bloody reliable and great for towing. About 100,000km ago we front mounted an intercooler and made a cold airbox to scoop from where the old topmount sat. We wound the boost up a bit ...
