Okay - this thread is for the benefit of those that wanted to be updated and follow the progress of the twin-turbo install in my manual TJII exec sedan. So here it is:
Installation started today, and I got the dreaded "we've got a problem...." phone call by 9:30am. I knew there would be issues, but I wasn't expecting a call in the first hour of work - but it wasn't too bad, and hopefully there won't be too many more dramas.
Anyone who's considering going down this path should take note now......... the standard wastegate actuators on a GT28 turbo will not fit in the required space. The solution - smaller Garrett (probably t25) wastegate actuators have been ordered at a cost of $130 each. We've decided to go with 5psi actuators instead of 7psi actuators, so it's possible the initial tune might only be 5psi. We have also decided against using the "oil and water line kit" from RPW, so all oil and water lines will be made up of custom speedflow gear.
Another update is that I have decided against trying to keep the whole installation "stealth" by keeping the intercooler behind the std front bar/grill. I have ordered a bunbury motorsports body kit which will help ensure the intercooler gets air without having to hang it out the front of a hacked at std front bar. And speaking of intercoolers - we've just discovered that new legislation in Qld means you can't get a mod plate for anything that involves cutting of any metal (structural or not), which will make plumbing of the intercooler extremely difficult, but hey, it's all part of the fun.
Anyway - I'm sure you're all sick of reading, so here's a couple of pictures to tide ya'll over.
