Thread: New heart and drive for D2

About UKP3200 for a 4.6 Turner Engineering crate engine (outright no exchange), 9.35:1 pistons with ductile iron flanged liners (the best), built up with gas flowed heads, cam, timing gears, rocker gear and all gaskets and seals needed to complete the build. Then add UKP500 for shipping with UPS and import duties at around 15% of the value of the purchase I think. Delivered to your door in about 10 days.

With the strong Aussie dollar that all adds up to around AUS7.5 to 8k, but that is for virtually a complete new performance engine that you just need to add your existing front cover, water pump, sump and injection system to.

Not cheap I agree but they're supposed to be virtually bulletproof .

You'd easily pay as much if not more than that for a TRS equivalent, not to mention their 5 litre option. And some people have had issues with their workmanship/customer relations skills if you can believe everything you read on the forums.

I will most likely get flamed for this but here goes, Why not adapt a Chev LS1 or LS2 into a disco? they're a cheap reliable motor with parts and hot up bit availible from your local corner shop.

That would be my choice if it could be engineered but I don't think they would allow a change from 4.0L to 6.0 L.

You should be able to get it engineered (mate has a GQ with 5.7l) but it would be more work than a 4.6 or 5.0 litre Rover engine.

Chev would need engine mounts, gearbox adapter, possible new crossmember or atleast modified sump, modified wiring etc. etc.

Also you end up with a vehicle that is mixed and matched and could end up with a number of issues that are hard to diagnose due to the amount of changes (as my mate found out with his GQ).

Putting the 4.6litre Rover motor into a D2 is also classed as an owner approved mod from my understanding as the D2 was released with a 4.6l from factory as long as brakes and suspension are changed or upgraded to match the factory equivelant of the larger motor.

In addition the 5.0litre or even 5.2litre by RPI engineering may not be difficult to have approved as I believe they are basically the same block stroked to a larger capacity.

I have not re-built or built up a Rover V8 but I have done other engines when younger with assistance from my brothers who are both mechanics. Small things add up to a big difference. I know that the Rover V8 is well specified from standard compared to what I was working on (Holden) BUT my thoughts if it were me for a very usable gain versus cost would be to go the 4.6 route but spend some money on the head and manifold - ie ported and polished heads with good valve gear - the right valves for torque, matched billeted camshaft, good quality timing gear, port matched exhaust manifolds, FULL balance including harmonic balancer being balanced, reasonably high compression but not too high so as to reduce off road tractability, and I reckon the difference between that and a stocker 4.0 would be very noticeable and very nice to live with.

Our very own P38aRover went down that very path ozscott,, He seems very happy with it,,, though he doesnt pick V8 RR's or D3's anymore,,,

...he should pick on the explorer motor V6 versions...

Ok, bringing an old post back up to date.

I have spoken to TRS about engine options and they have recomended for my application to go with a 4.6l.

So I am looking at ordering a brand new built 4.6l with reconditioned heads and having the swap over done in by my mechanic in Brisbane.

After talking to them for low speed torque applications there is no point in going for different heads etc. as they only give an increase in the top end of the rev range.

As part of the engine swap I also want to monitor the engine and transmission outputs.

Is there a engine monitor unit that is able to do, I was thinking the EMS1 but I can see any installed with a V8;

Transmission Temp
Transfer Case Temp
Coolent Temp and Level
as well as any other items like oil pressure etc. that should be monitored.

I already have a LED 52mm dual battery guage with low voltage alarm etc.
