Thread: Conversion, has anyone done it?

Now that I've got your attention.

1UZFE VVTI, 6bolt mains (std), 4 lt, all alloy quad cam,
cam specs
intake 321deg @ base
exhasut 319deg @ base

104deg intake lobe separation
105deg exhaust lobe separation

257deg @ 50thou

408thouh lift from base

165thou intake lift at TDC
145thou exhaust lift at TDC

VVTI mechanism custom modified to suit cams

4 x nissan RB26 twin inlet throttle bodies atop custom 3dcnc alloy adaptor, 45mm bored to 48mm with shafts milled down to 6mm (equivalent to 45mm with no butterfly or shafts)

Custom Argo rods with Custom pistons from specialized piston services in melbourne (short skirted, oversized pins, modified rings/grove heights)

Aforementioned heating issues are not ecu related, he's plumbed something wrong, I've never seen a heating issue (incl twin turbo and s/c and turbo - s/c conversions). Engines are cheap (non vvti cheaper and simpler). Iron block is a 2UZ, 4.7 is 3UZ (but very expensive). Anyone who says they don't have torque needs a 6 foot mirror, some viagra eyedrops and take a good hard look at themselves.

Im not sure thats the greatest engine for a rover but then I like a tractor engine more than a race engine...

no denying that engine makes a bootload of torque but its where it makes it that is the problem IMHO the max torque is way to high in the revband. I like the lazy feeling that a torque curve that starts somewhere near idle and is done and dusted by 2000ish RPM..

Isuzu. Same configuration as the cummins, but turbo and intake are on different sides which works very nicely for a RHD rover.
With a 4BD1T in a rangie, the axle weights are damn near even. I've got 1130kg front, 1170kg rear.

JustinC's got a similar setup.

Justin I was gunna get a half cut Soarer or Crown so wouldn't have a LC gearbox and I would be pretty certain that using the Soarer or Crown box would be out of the question?? Hmmm decisions decisions????

A large rover motor (4.6) would be better, cheaper and easier.

Toyo cams are extremely conservative, in their engine designation system, a 1UZ-FE is; first gen, UZ series, FE head design. (designed for fuel economy) GE heads are the performance heads (like the famous 4AGE engine).



Check original profile vs the weld/grind. 320deg + is probably a bit over the top for off road but you can move the torque around quite a bit. Get a vvti model and a autronic (our plan) or motec with vvti control and you're set. We're looking at pulling torque down to around 2200 to 2500 up. Red line at 9000 to 9500

Matt and i know a bloke who has a Lexus V8 in a Toyo Middy, its a Beast.... But the engines dont like to punnished...... they die....

Wouldn't say that, the motor was of an unknown quantity when he put it in, only span bearings, being jap import, probably NEVER has an oil change

Hmmm looks like I have started an interesting thread here. I had originally looked at the 4.6 but found they were hard to come by and the ones that were available were outrageously priced. The Lexus quad could be purchased in a front cut set up for around the $2000 mark. Even the imported 3.9s were up around the 4-5k mark.
