My project - N.A. B2500 conversion to turbo
Hello again.
Thanks a lot for the warm welcome, much appreciated.
Yes this will (eventually) be my daily driver.
The engine is a WL-31, the naturally-aspirated version of the WLT-31 (turbo version), installed on the South East Asian version of the Ford Ranger diesel.
Here in the Philippines the Ranger is a mini-truck (<1 ton class) with a crew cab body.
The WL-31 is a 2.5 liter, 12-valve, overhead-cam, inline 4 diesel with turbulence chambers and a Bosch VE-type distributor injection pump.
The pickup comes with a 5 speed manual transmission and the redline is a respectable 5000 rpm.
The WLT-31 is the turbo version.
The 2 engines share the same cylinder head, valves, camshaft, crankshaft, connecting rods and oil pump.
The main differences are:
1) the turbo engine has deeper pistons with oil galleries in them and a slightly lower compression ration 19.8:1 vs 21.6:1 for the N.A. engine.
2) the turbo engine has 2 counterbalance shafts and extra drive gears for them, which the N.A. engine does not have.
The standard turbocharger for the WLT-31 is an IHI RHF5 with water-cooling and an internal wastegate.
I imported a Chinese-made knock off of a GT1849V vnt turbo, along with a 45cmx30cmx76mm intercooler, piping kit and 38mm external wastegate.
The wastegate is set to open at 0.8 bar (11-12 psi) to keep engine stresses and turbo speeds down as well as to reduce exhaust manifold pressure.
I chose the small turbo for very early (off-idle) response and rapid spool-up.
Any advice you can give me will be very much appreciated.
Thanks!
