rover v8's (possibly tiff?)
right probably a stooopid question but....
is there only 1 model of the rover v8 engine?
ie the same one from the sd1 is the same as the range rover?
looking at something a bit lairyer for the e36 and was hoping yb but
far too expensive to buy/run/turn over/look at
i just really dont know fook all about them

Avoid the P6 v8 as it has a rope seal crank, avoid rangey as it is low comp, there is 3.5 3950cc called 3.9 and 4.0, this is the SAME cc and the later the engine the better, when they were owned by BMW, the block was re-engineered, with cross bolt blocks, and close fitting caps, as they can suffer from crank walk.
The cross bolt although was not drilled or used on the 3950cc varients, but of course still had close fitting caps, and was stronger as a result.
There is also 4.6, and the iceberg engine went to 5.2L
The most common one is the 3.5 SD1 V8, and that is 9.35:1 compression ratio, which is a bit low, the fuel injected in the vitesse(SD1) used better wasted valves, had better ports, etc, there are single plenum injection and twin plenum, though this was just a twin air flow metre plenum, rumoured when developed by lotus to be 220bhp, as opposed to 190bhp for the std vitesse 3.5, it never was.
There are many types of managemnet, hot wire flap etc, the best std one is probably/arguably the LUCAS 14CUX ecu, where Mark Adams has done a lot of work, power wise, and is well regarded.
As std the power on a carb 3.5 is 155bhp, the torque is around 195lbft at 2000rpm, so they are about low down grunt, they respond well to a decent cam ie piper 270.
One major drawback on carb versions is the clockwork dizzy they use with it.
The later the block the better, but whjatever block make sure it has the cam chain holes drilled in the valley ends, this lubes the cam chain, and stops them giving up.

Many many more than that, in cc as well as design differences.

You coming shopping with me
So in a nutshell what would be the best?
The low comp 3.5 sd1 is it low enough to lob a blower on without too much(expensive) work?

stick a 350ci chevy engine in it, you can get the kits to fit them in beemers from the states and if you go on the summin racing web site you can make it put out 420 horse with torque to match with a cam intake and exhaust, and they sound glorious at full throttle! rover engines are shit unless you spend serious money on them...imo

I know of two V8 chevies for sale if interested.
RV8's can be made to go well, but are not the cheapest way if tuning anything beyond mild, although twin turbo's can easily be fitted, on std CR, and have been many times, like Nick Manns Morris Minor.
I've seen a 4.6 with 460bhp but 580lbft at 2600rpm, in a rangey.
I can get you chevy bits, even s/h engines cheap, at the mo as I know someone selling some, and a shed load of bits.
I must admit if I was given the choice between chevy and RV8, it would be chevy purely down to price of bits, I can get a set of 8 forged pistons for these for less than the cossie of 1 for the cossie, just for example.
Reliability is not an issue, my dads RV8 is around 220bhp but 280lbft, does 35mpg on a run, we fitted it in his xr4i with a 3.14:1 diff(sierra diesel), the point is you get speed with no effort.

I have had quite a lot to do with the rover v8 as i did my apprenticship at Frogs Island 4x4 and worked there for years.
personally i would stay away from the 4.6 out off the p38 rangerover as those are prone for liner problems. I have changed engines for this problem with as little as 20k miles on them. imo i think the late 3.9 engine from around a 1993/94 rangerover would be the best for the money. I have fitted turbos and superchargers to theses and have had reasonable power and good realibiaty. Years ago i built a 3.9 and fitted a Janspeed single turbo kit using the EFI setup that i put in a Hillman Avenger and it pulled like a train, it would blow the gearbox to bits it you was hard with it, and i built this for around £800.
What gearbox would you use. The lt77 from the sdi isnt a bad box but they wont take loads of grief. The best one to use is from a tvr which is a T5 box, these will take most things a rover v8 can throw at it.
Your other option is the 5.0ltr version from a tvr but i cant see these being that cheap.

re v8
i have had 3 sierras with v8,s in them if its not injected it will only make 150 ish bhp standard early efi will do 190 bhp standard for cheap mods you can use bits from a xj40 injectors throttle pot etc but if you want something light powerfull cheap 1994 on 540 bmw with a 6 speed box or 96 on it has the 4.4 v8 all that for under a grand and if you are putting this in a sierra you can recage the diff as it runs the same system of diff and shafts i have seen it done with a 750i v12 into a xr4i mine is getting a 327ci corvette engine next good luck

I would only use the Chevy engine if it was one of the new all aluminium LS jobs, the old small bloack was very heavy.
Best bang for your buck is a 5 litre Ford Mustang GT engine, weighs less than a Chevy and comes with forged pistons. Fit a couple of turbos and you can have 500bhp without having to take the heads off
I spent many thousands tuning a Rover V8 and it made good power but there are better options....

I,d like to know where you can get a 4.4v8 bmw engine and 6 speed box for less than a grand ??? i have been looking for exactly that for nearly 2 months now and the cheapest engine i can find is £1100 plus delivery ! as for an e39 6 speed box if you can ever find one its allmost as expensive as the engine! i have found plenty of the e34 4.0 units but they arent the same .
if you know of any e39 units please let me know so i can grab it and get on with my build

Could always go auto for the box, a nice ZF 4hp22 with 24 components and a bmw 850 tail end(to convert to 2wd).
I have the very box myself sat in my garage, built by the master himself, Jonh Lovegrove of ATP in Bristol, warranted up to 700bhp, all parts included, was going to use it on my V8 diesel project, but dad nicked the xr4i off me!!
