Just having a little V8 dream now, I blame my North American heritage there. (no not American, further north)
How many MK1 out there have the 3.5L V8 from the old Rovers?
What does the extra weight do to the feel and handling of the MX?
How much on a 96 1.8 Auto Eunos has to be changed in the conversion?
Can the auto box handle it, Shaft? LSD? Brakes? Suspension? How much more weight to the front does the V8 add.
If this dream was just power driven then Supercharging or Turbo is the way, but it is purely the sound of a V8 through dual pipes that is behind this dream.

Who does these conversions? and what would the bill look like??

Back to the power thing, bore the 3.5 to the 4.6 and supercharge it

i think people are tending to use more modern V8s - there's a build thread in members rides with one out of a lexus and in the states they tend to use the lumps out of corvettes.

I believe if you get one of them aluminium engines the weight difference is minor cos the 5 engine weighs a ton.

I've seen the Flying Miata with the Corvette engines, I was wondering what conversion where being done abit closer home. The reason I went for the Rover V8 because there are still so many out there,Rover P6,SD1, Range Rovers, TVRs at the head of the list, it was a workhorse of an engine.

I put a Rover V8 in a Triumph TR7 some years ago.....the original TR engine had a large iron block... and looked heavy.... the Rover V8 weighed even more tho....I could feel the weight difference on the front end

I'm under the impression, from what I've read here and there, that the LS1 V8 from the Corvette is a popular conversion. Apparantly, because the LS1 is made entirely from alloy and the stock B-Series is made from bits of the moon, the LS1 is no heavier and doesn't affect the weight balance. It also hoofs out 300+ bhp and probably just as much torque.

Couldn't tell you about the Rover V8 though. I'd imagine it's a heavy thing. Certainly worth looking into as they're more common though (and an LS1 with 'box on eBay is about three grand!).

There are 4 Rover V8 engined 5's I'm aware of.

The costs depend how you do it really.

You'd use the Rover engine and box its a bit heavier but not much.

PM gas guzzler if you are genuinely interested but if you paid a garage you'd probably be looking at a ?4k+ bill for the conversion.

Find an old TVR, a Cerb or Griffith. Pretty sure they're the Rover V8 lump but have already been fettled with for extra oomph

Thanks Mark, all my questions answered, I'm genuinely interested but it might be awhile before I can raise ?4K+ for the conversion, then again ?4K could but a old TVR S1 with the rover engine and I should just supercharge the MX, Oh well back to work to fund this dream.
PS. You are partly to blame for this dream, I bought the Racing Beat Dual Cat Back Exhaust off you in January, and it sounds sooooo sweet with a 4 pot, it makes you would what it would sound like with a V8. Good luck with your recent (V?)6.

I meant strip the engine out and put it in the 5


The local rolling road to me is a tvr specialist and i've enquired about the possibility of a speed six lump finding it's way into my engine bay

the carbed 3.5 from the p6 was 150bhp ish new iirc, and many of its horses may have jumped the fence by now.

it used to shift my uncle's p6 along nicely but it was far from....sporty.

i'd look anywhere but the rover v8 if i were you, but it's your dream

I looked into it quite deeply and to get a decent lump (over 200bhp) you need around ?1250+ for a used engine and most TVR ones just had a cam and ecu and they fetch at least ?1200.

And the S series came with 2.8 / 2.9's apart from a few S3's which had V8's but they are significantly more expensive.

The TVR Griff and Chim were Rover V8 but the Cerb was TVR's own AJP engine.
Rover V8 is not a heavy engine and is able to produce high bhp easily IF done correctly. You can get a full Rover V8 engine on ebay for not much cash. If you can weld and like a challenge go for it.

Meant to say the Chim but have got Cerbs on the brain, probably due to the one down the road from me. Although an ajp8 powered 5 could be quite amusing.

Thought the ajp8 wasa reasonably reliable and that it was the speed six that fell to pieces.

BMW V8's are becoming a more popular choice for kit cars these days as you can source a whole car quite reasonably, they give good power straight out of the box and are light weight
I've measured them up and they are too wide to fit with std 5 chassis rails the Lexus was the only modern cheap V8 I found that fitted

However I suspect they won't be cheap for long as I know of several conversion kits in the pipeline - one for Discos as the Rover V8 isn't all that reliable plus its a 40bhp upgrade.
