simonjrwinter Posted March 24, 2015 Report Share Posted March 24, 2015 (edited) Now I'm all for engine swaps (mine has a rover V8) but a V12? (BMW) Edited March 24, 2015 by simonjrwinter Quote Link to post Share on other sites
RobinTR6 Posted March 24, 2015 Report Share Posted March 24, 2015 Ummmmm, that should give a power boost and some very smooth running albeit that the rest of the car will need some serious uprating, suspension and brakes. Guess this is one of our American colleagues where a V12 isnt such a big deal as here. Having had a couple I must it great to have that may cylinders working for you, smooth , effortless powere delivery, nice...not for my current TR tho. Quote Link to post Share on other sites
TriumphV8 Posted March 24, 2015 Report Share Posted March 24, 2015 Main advantage of the Rover is its weight, much less than the TR6 engine and its small size due to the non-ohc. All fits perfectly under the bonnet and the inner wings can be left untouched. Power is more than required and smooth running more than expected. The V8 goes with the 5 litre beyond 350 BHP what makes the TR6 like riding a cannonball..... At a bit over 2000 rpm it has the max power of a CP TR6 and just than the fun with the V8 begins.... No need to fit a bigger and heavier engine and create nasty understeer! Quote Link to post Share on other sites
Daz Posted March 24, 2015 Report Share Posted March 24, 2015 I would think fitting the V12 lump into the engine bay (as picture) would not be a major problem, fitting all the ancillaries ....... may take a little longer. Quote Link to post Share on other sites
simonjrwinter Posted March 24, 2015 Author Report Share Posted March 24, 2015 I'm sure the weight wouldn't be a huge issue as it's an all Ali lump but surely the V12 horsepower and torque would be too much for the TR6 chassis? Quote Link to post Share on other sites
elclem1 Posted March 25, 2015 Report Share Posted March 25, 2015 Too much for the insurance??? Quote Link to post Share on other sites
Mark Shezbo Sherratt Posted March 26, 2015 Report Share Posted March 26, 2015 As I have said on here a few times before..a BMW 6 cylinder 3.0 litre (as fitted to the Z4 and 530 etc) would be my choice of "non-original" engine to fit. Why? It keeps the "sound" a TR6 should have. BMW 6 speed box to mate to it is a lovely thing The engine produces 230bhp (fast enough in a heavy 5 series - a TR6 would fly with this lump) It is a lovely engine - with very few mechanical whoa's They are a nice light weight unit.....and they fit!

simonjrwinter Posted March 26, 2015 Author Report Share Posted March 26, 2015 That would be a cracking lump. Someone in the US has already done the BMW thing, Simon Quote Link to post Share on other sites
RogerH Posted March 26, 2015 Report Share Posted March 26, 2015 If you fitted a BMW lump in a TR6 would it ever break down - probably not. So where is the pleasure in that. Taking a 6 out not knowing if it will ever return is the excitement of it all. Covering the cars behind in a thick layer if unburnt fuel is also a plus Roger Quote Link to post Share on other sites
Peter Cobbold Posted March 26, 2015 Report Share Posted March 26, 2015 There's a simple way to keep the TR engine - any TR engine - and get 25% more torque, and from low rpm. Peter Quote Link to post Share on other sites
barkerwilliams Posted March 27, 2015 Report Share Posted March 27, 2015 My pi seems to have plenty from the right hand pedal, it's just the centre pedal seems a little ineffective. Trying to rein in a V12 would be err...an interesting; but not a long lived problem. Once someone has sorted out an aftermarket ABS put me down for a set. Alan Quote Link to post Share on other sites

Why - are the front brakes locking up on you? Might be tired front shockabsorbers and springs allowing to much weigh transfer to the front. Peter Quote Link to post Share on other sites

I looked very seriously into this swap, main issue is getting the newer BMW units actually working. They use the OBD II engine management systems which are highly integrated in with the rest of the electronics package... It turned into a nightmare to sort and there are not many aftermarket ECU's which will competently work the dual VANOS system. If looking at a BMW engine, go for an early one which works on the OBD I system (which is what the chap in the US did). Although there will be someone along shortly who has successfully done this with a 'newer' BMW power unit... Quote Link to post Share on other sites
TriumphV8 Posted March 30, 2015 Report Share Posted March 30, 2015 With no doubt the BMW 6-cylinders are among the best in the world. Anyway, to avoid the TR6 engine problems and swap to a BMW R6 for me is like building a bottle-ship without the bottle: It can be better in many details but thats not the aim! (and the difference between my 180HP straight six to the BMWs 230HP is noticeable but nothing against the difference between the 180HP and the 350HP of the V8 especially because the torque pulls the car from idle like a train in any gear) If you look at some smaller car companies in GB like Morgan, MG, TVR, Ginetta and Marcos much of their famous rumours come from their V8s what in most cases was the Rover! It can be reduced to a simple sentence, Wildcats Ian Richardson told me: "Once V8, always V8" The car becomes different and accelerates in an easy way that best must be driven to understand. That in my opinon is the reason that Morgan could sell their products over that long period and after trying to swap to the 6-cylinders they had to accept that the market prefers the V8s. Also German Wiesmann had some R6 and V10 in the programm but they also had to accept that the people prefer the V8 although the V10 is better in many cases. Here it was not the performance, The "M" engines perform excellent and the V10 has 507HP! It is simply the feeling you have driving a powerfull V8. Quote Link to post Share on other sites
InfinityJon Posted October 24, 2018 Report Share Posted October 24, 2018 Do you recon it’s worth doing a 2.5L BMW? And would you mate it to a the bmw gearbox or the TR? Modified drive shaft and bmw rear diff or TR buts from the gearbox back? What are people thinking? Quote Link to post Share on other sites
InfinityJon Posted October 24, 2018 Report Share Posted October 24, 2018 When people say it drops straight in, does that mean it fits or it fit if you get the air slitter out and modify a **** tone of tin work? Quote Link to post Share on other sites
Mike C Posted October 24, 2018 Report Share Posted October 24, 2018 Don't know about the UK , but in Australia I'd talk the job over with a licenced registration authority certifying engineer before I did anything, assuming I wanted to drive the finished product on public roads.
