Once I removed the boost controller the wastegate kept boost at about 12 or 13 psi and egts stayed well under 600.

That is 800-850 pre turbo!!! Lucky you didn't kill the turbo or a piston... Just shows how strong these engines are. Factory spec for a genuine T is 750oC max pre turbo.

Sounds like there is some room to optimise your setup.

If I was to dial in upstream temps of 800degrees I'd have a twisted lump of geartrain to deal with!!!!!!!

Even at 650 I was lunching things, and having traction problems.

Something isn't right, surely?

I've hit 900C a few times when I wasn't paying attention.

Thanks Brian.

This is the way I'd like to fit one. Are there any practicalities that have to be dealt with? Its pretty tight already on that side of the engine.. do you have to move things to get it in?

Not really. About the only thing is that you have to have is the twin oil filter setup as the single upright one is in the way of where the turbo sits. The exhaust runs from the manifold under the aircleaner brackets to the turbo.

...But with 31" tyres you at least would get some slippage before breakage

(On another note, I will be working on the 110 etc over the break, so possibly be getting some pics of the front shock brackets etc for you if I get that far. the running gear and engine etc is all installed, not much to see so no pics yet. Stay tuned

Post up some piccy's anyway JC - it might be boring/normal stuff from your perspective but you'd be surprised how valuable just general photos are to those of us that aren't working with the vehicles every day.
I'm sure you've seen/worked on hundreds of them, so I know everything you've done with it so far will either be as per factory or modified for a particular reason from experience.
Either way its useful reference...for me at least

Thanks, I look forward to it.
I'm not sure my tyres would even make the 31" mark.

Just checked mine today. 380-450 @ 100 km/h unladen. That is ~ 180-250 where both of you are measuring...
