With a plenum that large I want it, but one question: "Will it fit"?

I'm worried about bonnet clearance and injector lines. Are you around to give us some measurements Ben?[/QUOTE

i have the same manifold but mine is a 4bd1.

May or may not be of interest, but I have been coming across a number of 4BE1 engines ('4BE1' lettering cast on side of block) with 4BD1 Heads ('4BD1' lettering cast on top down one end on injector side). Some have had this manifold.

I don't think he believed me when I indicated some were running 20psi boost.

A wastegate is starting to look a bit optional for these motors.

my 'conservative economy' set up is 15psi with 550,000km up. these are a tough engine try runnnning 10 to 12psi through a 2l, 3l or 2h etc and see how long they last.....i've had no wastegate connected since about a week after the turbo and engine went into the RR...

I've got one, it's in my garage.
It's not going on my engine though, I need to wrap it up and post it to Randy (Carcrafter) in the states for his big power experiments.

I plan to draw it up in solidworks at some stage. Really should get onto that.

Dougal I was looking at a jeep the other day which I think it may hav had a 3.7 5cyl turbo mercedes diesel (not quite sure but im guessing that was it) but I had a quick look at the turbo it was running a garrett gt22v not sure of other numbers but im asuming its a vnt would this turbo be a good option for the 4bd1 you reckon ?

Yes if you can control it. Later VNT turbos are electronic control.

It's probably a 2.7L diesel, that sort of turbo will be fine for 15-20psi. I have a GT2256V here from that engine which I plan to fit at some stage.

Yeah I dont think it was electrically controlled I didn't see a box of the side of it like the puma has but trying to get a vnt will be the hard part without paying a fortune do you reckon that your vnt when installed will be on par with bush65 compound setup ? Are you considering intercooling yet ?

Oh yeah 2.7L my mistake

No a single VNT won't compete with a compound setup.
A single VNT is the best drivability you'll get with a single turbo. A compound set will kick it's arse.

I've been intending to fit an intercooler forever, even had an intercooler in the shed for about 4 years now. Life keeps getting in the way.
