A red hot glowing chunk of carbon in the cylinder shouldn't cause knock, glow plugs can run red hot without inducing knock! It really sounds like a timing issue. Whoever reconditioned your injectors should be able to diagnose the problem for you (for free)!

Was the engine knocking before the injectors were replaced?

I think that the real issue is application, each form of charging (crank driven versus exhaust driven) both have their good and bad points. Having driven a rootes charged diesel in a higher mileage application (daily driver) (800-1000 kilometres per week) I realized that the noise levels of the...

Looks like a lot of fun, that's how the Toyota should have made them!

Damn! I've got 2 of these and can't use them!

They're the numbers on the entrance to the turbines, the other numbers are 15H and 15R.....

A few years back I made a good gain in performance by relieving excess pressure in the exhaust manifold of a C.T.20 turbine on a 2lt engine by enlarging the wastegate and modifying the entrance leading up to the wastegate. Dougal thinks that it's impossible. I think it has to do with the flow of...

I've got 2 spare rhb5s, one is 37 A.R., the other .38, the factory turbo is covered in heat shields so I don't know what A.R. it is until I get a chance to take them off.

I don't drive the 2lt much anymore, just keep it as a spare set of wheels. I'm presently modifying an exhaust manifold for the 4jg2, I might even try the rhb5 in place of the rhf5 as I have one sitting in the shed. The rhf5 is too slow to spool in factory form, no boost until 1700 revs.

When you only have around 60/70 rear wheel horsepower an extra 5 h.p. is easy to notice, the best power gain in turbo form came from relieving backpressure on the factory turbo engine, porting around the wastegate exit (and shaping the inside of the turbine entrance leading to the wastegate)...

The exhaust manifold on your engine is probably a better design than the 80s/early 90s manifolds. I put a devider in my 2lt (1985 design)manifold to direct the pulse of exhaust gas toward the turbine, the standard manifold layout is a bit average, the flow leads from cylinder 1 straight...

I have previously stated that I think turboed diesels are a great idea, a turbo is about 1/20th the size of the engine and can move 3-4 times as much air as what the engine can. The internal combustion engine is quite good at converting energy into a usable form, but is not very good as an air...

subtly threatening to shoot someone is pretty piss weak Dougal, maybe you should "go do it the first time with your clay blow up doll" har har

I see you have been busy editing! Quote"Crank power turbocharged = 80.7 -10.7 = 70kw Crank power supercharged = 80.7 -13.5 = 67.2kw" Unquote Thankyou, thats all I was after. Now where does the extra power come from after parasitic losses are taken into account? As far as I can work out it has...
