Let me introduce myself :- I'm Dan from Gladstone Qld Australia. That's done.
I've searched a lot on the net for answers and there is a lot of info on the Ricer Forums but not covering diesel engines. This Forum comes up trumps (not political) on that and I'm hopeing some of that knowledge will be sent my way.
I own a Mitsubishi Canter FG637 (4x4), it's engine is a 4D33 four cylinder 4.2 litre.
I've built a custom exhaust manifold for it and polished the inside. The turbo at the time that was recommended for it was a TDO6SL2-20g (turbine AR 8cm) that works well at road speed but not when offroad as boost comes in to late.
Now this has been running for a while. Let me go into it a bit more. Fuel screw has been opened 1.5 turns I see boost start at about 1700Rpm (2/3psi) and climbs steadily to reach 11Psi at around 3000Rpm. This turbo doesn't have a wastegate and no external is fitted (could be done if necessary). We also have a 3" exhaust fitted from turbo to end including a straight through muffler which is out just before the rear right wheel.
I know now that the turbo is to large for this engine - After a lot of reading. What I need or a least would like is some one with a lot more knowledge than me to be able to recommend the right one to fit.
Like I said it is good on the highway but when we are just steadily going down a road (1800 rpm) and give it a little on the throttle because of a little bit of incline in the road my exhaust temps start to climb and fast. I know from over fueling at next to no boost. My injector pump is not fitted with a boost compensator so we can't adjust that (another thing we are working on).
I'd like to see boost come in at 1300rpm (if possibly). Engine red line is at 3400rpm.
I know quite long for first post on this site and if your are interested in more of my vehicle and trips I'm on Expedition Portal - search Aussie Iron.
