Thread: Engine conversion possibilities...

cheap lexus V8 :?: . the cost of conversion ie clutch set up or auto set up, exhuast changes, computor and wiring, fuel line, accelorator cable. radiator modifications the list will go on. Your cheap lexus V8 will cost you more than you think. advise from someone who does engine conversions! stay with the rover V8 and upgrade the computor, a good air filter and exhaust to match. even better supercharge the rover v8. oh be carefull of the stated 190kw of the lexus engine I seriously doubt it. you will be very happy with the result. oil leaks/weepage with a rover is just normal. do as most others do degrease your engine on a regular basis as part of normal maintenance. hope this helps

I've actually had a 1UZ conversion done before (in a Cressida), and yes, it was quite expensive. Then again, we did use after-market engine-management, and did quite a few other things to it which we wouldn't be doing to the Disco...In fact, the intention is to use a Crown half-cut (which can be had for approx. $2000 all-up), and transfer the engine/computer etc over. Then we'd need to use the front of the auto's bell-housing as an adaptor plate etc etc.

As for the stated power, our Cressida was dynoed at 153RWKW with no modification to the engine, save a 3" exhaust off standard manifolds, so I believe the power as stated to quite verifiable. Just need to know if it will fit, before committing myself (apart from doing the cost sums to see if it's a worthwhile exercise).

A 351 cleveland will fit with a squeeze. the lexus is wider again I think. 153 kw at wheels thru about 2.9 diff ratio onto 26inch tyres. does give you about 190 at the flywheel. however you need to consider what reduction of power will occur thru auto then transfer to large large tyres. my guess about 100kw. I talk of power at wheels not at the flywheel. much more accurite way to guess performance with the addition of vehicle weight.

A conversion with the use of GMH v8 will be easy, someone will do a conversion kit. and will fit with ease. food for thought.

Why not get a 4.6 rover block and then you can rework all ancilleries as required and all will bolt on with no mods?
If this is of no interest go with a power plant that someone has manufactured a conversion kit for.
If this is of no interest buy a Lexus!
PS only poorly serviced drive lines leak. If you look after it the car will serve you well?

There is a guy on the Lexus forum with one in a Range Rover.

A guy in NZ has one in Hilux and was of the opinion that they would not be so good in a Range Rover/Disco because the torque comes in relatively high.
When you quote 2 grand for a 1UZ, thats an old 1UZ which may or may not be good.

For low down torque there aint no substitute for Cubic Inches.

I have put a Thor manifold on my 3.9 which , along with heads and Unichip,gives over 50% more power between 1000-2000 and tapers to nil at 3000.

But WHAT a difference in drivability. Low down torque is the key.

Gen 111 is the way to go if you want big power, but also needs big money as you have to upgrade the trannie , which is the most expensive part.

lexus engine = good street car.

high revs torque high up rev range.

if doing ngine swap be prepared for hassles ect.

easy option rebuild rover engine to specs you want.

harder option swap in a chev or holden 350-355 ci v8 heaps grunt low revs.

other optiion swap in a td300 or the like even chev td v8.

think about what you want from the car, thnk of how much $$ you want to spend and so on.
