It's one we considered for my wife's B, and still might if we have issues getting a Speed 6. Fitting it will be tight, mainly around the quad cam heads which is the main difference between fitting a KV6 in and the Rover V8 (apart from being a bit shorter). Probably need bulkhead mods, esp in a chrome bumper car. Gearbox, we'd planned on using something like the Toyota W57 or 58, used one in my K Midget and it's quite compact compared to the likes of the Ford Type 9. Bonnet clearance would be close, it will depend on how far back in the bay you can get the engine. The 'C bonnet would give you more clearance, I would expect enough.

Induction would probably need some modifying, but I had never got round to working that out exactly. Might be possible to use the standard system with a feed from the windscreen grill though, but we'd probably have ended up with a blower on top so would've been quite different anyway. Obviously need a lot of wiring adapting, and depending on what you want to do with the engine an aftermarket ECU would be a good idea.

Rover V8 conversions everyone does, it's a bit cliched

K4 would certainly be an easier conversion to into the 'B, very little needs doing to physically fit, although the KV6 would be more interesting. The only reason we're not going with it is we want a straight six, cos straight sixes are awesome. And the Speed 6 starts at 360hp...

Interesting concept... Why did you choose the KV6?

Good luck with that ..... If your talking about a TVR speed six I hope you have a bottomless wallet .....those engines were poorly engineered and have the potential to produce invoices that make a Ferrari owner cry...... having said that ...... I DO like your left field approach and would love to see and hear it when its finished.

I can vouch for that, I used to be a service manager at a TVR dealer!

because i have a spare v6 and ecu etc and dont want a heavy v8 and dont want an old 1970's engine and the thought of a modern v6 in an mgb with custom twin side exhausts is very appealing! i know the heas will be an issue so thinking triumpth throttle bodies, im not looking for massive power but in a light mgb it should be quick. just trying to find a suitable chassis now as i found an mgb specialist near me ,

Yes I know, however with some research it appears cures aren't the end of the world. It has a lot more power and torque than a Rover V8, and is lighter. Mind you, I have just discovered the price of DB7 V12s is not dissimilar to the Speed 6, and they're narrower and shorter than a Rover V8, and only ~150mm longer. A little heavier but not much.

420 bhp and 400 lb.ft in a ~1100kg MGB, should be fun. Although it might result in some more modifications to my Midget to make sure it's faster than the wife's car...
