Turboing a non turbo diesel

[DanCo]

Hi all, Have just purchased a 92 2.8 diesel. It came with a turbo and manifold, just wondering how much work it is to turbo it. Do you have to do any internal engine mods?

Not usally mate. just as long as you dont run really high boost. Really just manifold and plumbing. Not that hard. If you have a kit to bolt on it should have everthing there! Then get it tuned!!

HILUXS GO GREAT TURBOED BUT DONT OVERBOOST THEM. THEY END UP BEING A QUICK LITTLE UNIT.put new axt kit on my 96 80 series i had. never got it dynoed etc tuned it myself. never got hot pulled 2 tonne easily(h/d car trailer and commo wagon) overtaking cars down highway. BEST MOD YOU CAN DO MATE. set at 12psi had 4inch + 2 inch + 33 bfgs and lots of steel hanging off it went beautiful. HAVE SINCE SOLD IT AND HAVE SPENT THE LAST 6 MONTHS TRYING TO GET MY NEW 2OO6 NISSAN 4.2TDI COILCAB TO GO AS WELL AS IT DID. MY old cruiser pulled so well down low it wasnt funny....OH I TURBOED IT AT 280000KM SOLD AT 340000KM. 5000KM SERVICES AS PER USUAL. OHC TOYOTA REV SO MUCH SMOOTHER THAN PATROL PUSHROD TOO. SOMETIMES I WISH I DIDNT SELL IT.

I'm hearin ya. I just strapped on an AXT kit. Now the 94 pov pack 80 boogies. The diesels really benifit from the increase in manifold pressure. Good advise not to pump them up too much. 9 - 11 psi is all you need.

There are no internal mods required. Just some oil and water plumbing. Air intake changes, exhaust modification ( you will need the stock exhaust ). Mine also has an aneroid on the fuel pump. It modulates the fuel flow dependant on boost. Greatly reduced diesel smoke on mine.

Really happy with the performance now. Would pull a bend out of the river ! Fuel consumption went up by 0.5 l per 100klm. Thats 70 cents. Tell me any other mod you can do with that power / economy increase and I'll do it !

It's excessive fuel you need to worry about, air compresses, the high cylinder pressures that break engines are due to to much fuel, the cylinder pressure after ignition(by injection) far exceeds that on compression otherwise the piston wouldn't go down.
