The next phase... what engine?
Having nearly got my 1972 TVR back on the road I am planning the next phase...
I want to include in that, an engine and gearbox swap for something a bit more modern and a bit more powerful...
The standard 2.5L straight six sounds fantastic and has a bit of torque... but it is a HEAVY engine and is not hugley "exciting"
So, what engine could I pop in there instead?
I guess I want something thats fairly common(ish) so its cheap(ish) to buy and fix...
I dont think a 4 pot would sound quite right somehow...
width of the engine bay is an issue so an shallow angle Vs are out...
So what engine should I look at?

Hmm... I hadnt realised that BMW made straight 6s.... that would be nice......
Any suggestions as to which one?
Likewise... which volvo engines/gearboxes would be the logical choice?

ovloV, BMW and Lexus have to be the obvious candidates really.
If you've money to throw at it then fitting something like a VAG V5 motor (as fitted to mk4 Golfs) would be an interesting option - unrestricted
they would probably sound good too.
I agree that a mere 4 pot does seem somehow wrong, bu then a Zetec or Duratec would be a cinch to fit and would give good reliable power too.

 Hadn't realised...!
BMW have been the stalwart of the straight six engine for decades, it's part of their ethos 
Your choice ranges from 2.3, 2.5, 2.8, 3.0 to 3.2 (IIRC) from adequate to M3 serious

I'd have said beemer six - if you can stretch to it, then the obvious choice would be the E36 M3 or M3 Evo - either 3 or 3.2 litres - the 3.2 is
320 bhp, and the manual box was a six-speeder. Sounds brilliant when you let it rev (it redlines at about 8000 or so), and loads of shove. You might
want some big brakes tho 
failing that, they made plenty of 6-cyl engines, as a general rule anything out of a 323 upwards would be a 6.

straight six from an M3 would be awesome!! They sound like they are about to bite your head off!!! Shame you could't fit a V8 out of an M5

Volvo straight 5 or 6.
Is there nothing you could do to improve the current engine?
How long can i resist the temptation to drop a V8 in?

Hmmm.... tidy...
Dont think I would want more than 250-300hp in that car anyway..... thats plenty quick!
What gearbox would work with that engine? (and I assume a different diff might be an idea... the old school triumph one might not like it)
And could I use Megasquirt to run the engine? Including the VANOS system?

BMW S5232. 3.2l. 320bhp, individual throttle bodies, 24 valves, 8000rpm redline, chain cam, equal length tubular headers. Or an S54B32 if your budget
will stretch, I suppose, but will probably be a more complicated installation from the electronics point of view - probably not worth it just for an
extra 20bhp.
Ok, its heavy but its a hell of an engine.
BTW, all proper BMWs are straight-6* - it virtually synonymous with the marque.

* The E30 M3 is a I4 of course, but counts as an honorary straight-6

The current engine is very heavy... and, I could spend around 500 getting the head done and fit new cams... but for that money I could buy another
more modern engine... spend a little more on engine management etc and have a LOT more power for the cash...
Could you stand the BMW motor upright a little bit if needed? or would I start to get oil starvation problems etc?

How about the two wheel drive single turbo older Nissan skyline engine, easy 300bhp, sounds great, nice and light and will never go wrong?

It's a TVR, they used to stick 289 Ford Hi-Po engines in them here. Makes them very hairy with about 350 HP with Shelby Mustang specs.
