Thread: Turbo

You need.................(big breath) The turbo, exhaust manifold, turbo oil feed line, turbo oil return line, water cooling lines, water pump, thurmostat housing, top radiator supply outlet (top of the thurmostat housing), intake manifold, air cleaner, air cross over pipe, stop cable bracket, dip stick, injectors, fuel injection lines, radiator hoses and if your serious about the conversion you could also change the, fuel injection pump, oil cooler, the engine fan, rocker cover, crankcase breather, oil pump, oil filter housing and last but most important the timing gets changed.
Sounds dawnting and thats because it is, in my opinion your far better off forking out the extra green backs and buying the 4BDI-T. As the turbo motor also has the treated pistons, crank, a different cam and oil injectors that spray onto the bottom of the pistons.
Any one that says there is no difference between the two engines either has know idea or is trying to sell you something.

In saying all that mine has had the turbo conversion, I'm missing the cam, treated crank, pistons, bigger oil pump, twin filter housing and different injection pump. I've changed everything else over, I was however rebuilding the motor compleatly as it had spent it's life on fraser island so everything was rooted and needed replacing anyway. So for me it really wasn't that much of a differance as I was buying the parts anyway. It was very expensive around 4k mark from memory.

I live in Darwin and frequently tow a boat long distances and the car performs great and dosn't show any signs of overheating, and it recently worked out around 10.5ltrs per 100km towing. That ain't bad, considering I was towing the boat an my mate behind me in a Hilux was getting 14-15ltrs/100km

Your probably better off spending some money on the G'box, or getting the R380 conversion done, I just did this recently and it's a different car to drive now, not a fruit truck

Hope this helps

Cheers

I recently got a brochure for a 4bd1 turbo conversion from a well known turbo specialist in Brisbane. The list of items was
garrett turbo with wastegate 10psi boost
over boost safety valve
manifold or adaptor
2 1/2 inch exhaust (incl flex section)
oil lines and oil cooler
water cooling lines and connections
air ducting to and from turbo

The conversion uses the existing injector pump and injectors, and existing oil filter housing.

have a look at the outerlimits web site. There is some good info on turboing a n/a 4bd1.

Ok larns has nailed it...

But if you use the existing fuel pump and tweak its timing (not the injection quantiies tho) you can get away with just enough to plumb up the turbo in terms of exhaust, air and oil (and coolant if its a cooled turbo) Its not going to do the longevity of the engine any favors but shes substantially over engineered in the first place...

If you do go the cheapo way when it comes time for the rebuild of the engine (should it ever need it) then you add all the extra bits n pieces..

Like Larns said. however i got away without changing the following: water pump, thermostat housing, top radiator supply outlet intake manifold, air cleaner, injectors, fuel injection lines, radiator hoses, fuel injection pump, oil cooler,oil pump, the engine fan, rocker cover. And i slightly modified the crankcase breather and the oil dip stick.

I would also reccomend fitting a pyro gauge (exhaust gas temp) and a boost gauge.

there was a 4bd1t stage 1 at the show in penrith with standard intake and exhaust manifolds. He had the turbo bolted on the intake manifold, and the exhaust run behind the engine and up to the drivers side to suit. He said it was 100hp on the dyno (i think he meant at the engine).
