Interesting choices. I must admit to be personally interested as my Toledo is a keeper and a future engine swap is always a possibility. Currently, mine has a slightly tuned Sprint engine on 45's making around 165bhp. It's a heavy motor though and I have another option sat in my garage from my failed Rochdale project, a VHPD K series mated to a BGH built Type 9 box. I'm just not brave enough, for fear of upsetting what is currently a very sweet car.

rude - An interesting thought, but I've looked into doing that kind of thing before and it ain't cheap, plus you end up with somewhat limited range. If I was doing it as just a sprint\drag car it would be a definite possibility. ChasR - sorry, forgot to talk about it in it's current state. Whilst I like the low down torque it's got, it doesn't put out very much power and consumes a fair amount of fuel to do it! Now this is in part due to the fact the execution of the setup isn't brilliant - a piggy back fuelling ecu being the biggest problem I'd have thought, but it does strike me that the tuning options are limited for that supercharger and bigger ones tend to be dearer than turbos. Maybe I should look at a super-turbo set up alolympic - If you've got it to hand and it doesn't require cutting or shutting to fit I'd be tempted to try it mate, if you've got the time and don't need the car. You never know, it may be significantly better, if not return it to stock I did consider the K-series but it looks like a fair bit of investment is required to get reliable power out of them.

I would suspect that, if its going to be used as a daily, reliability is really going to be of primary concern? Have you considered looking out for a manual Omega V6? Omegas are getting scarce now but barely MOT'd ones do come up for silly money and it would enable you to use a complete donor to transfer the running gear from. You will get the engine and box with any other wiring needed and you will end up with a quick, tourquey car that wont be terrible on fuel and will deliver the kind of power you would need to breathe on other lumps to extract. Just a thought

Saab engine a good choice, but ~400 bhp going to be costly. Stock engine (or a 234/235 hybrid) is good for around 300 without major expense.... UKsaabs the place for better info.

I'm just not brave enough, for fear of upsetting what is currently a very sweet car. This is very interesting. I'd have thought with the similar power outputs you would have been tempted to stick with the Sprint engine. I can see why you are tempted to switch it! I'll have to read the Rochdale project thread again, have things really got that bad with it? Badger, that's fair enough. I figured it may have been fuel consumption. I'd have thought you'd be on 140ish BHP in that case. Part of me is tempted to say go turbo with your engine but limit the power to 200BHP. An ECU like an ME221 would also keep things easy. The turbo would also be fitted on the side of the engine that doesn't have exhaust manifolds in the way etc. You'd also lose a few niggling issues regarding engines swaps this way as well. That is if the rest of the installation stacks up. But OTOH those Duratec HEs are tough old engines, but I can't see it being cheap to source an engine and then buy all of the bits like the TBs etc.

I thought the last thing my old Sprint needed was more power, low down torque yes but not power. In terms of actually driving day-to-day, I much prefered the 1850HL and TR7, in fact I thought the TR7 2L/8v engine would be better for the 'Sprint' and the TR7 with the 2L/16v (as they did do in fact, a couple TR7 'Sprint's).
I loved the Dolomites I had, great fun but not really great to drive in the first place, unlike the TR7 which had so much more potential.

Again, thanks for all the replies guys - there's a lot for me to think about here! After starting this topic and having gone for a drive in it yesterday I'm finding myself leaning towards the MX5 plant or the Duratec, whereas on paper I was leaning towards the B234. I think I was mainly seduced by the big power figures I had a better look at a quattro gearbox but it seems large and heavy for what it is and there's a fair bit of division on how successful such mods are. rude From memory the Prius uses a weird hybrid drive system where the engine drives the wheels as per a normal FWD car, but is assisted by the electric motors through the same mechanism. That would unfortunately be a bit of a curse word to convert to RWD, nevermind the electrics! ChasR I think 140bhp sounds about right through my "seat of pants" dyno, though I could be wrong! The current setup does need to have work done on it - I want to shift the engine forwards an inch or so for better access and will need to shorten the gearshift on it to get the gearlever handy. New mounts may be on the cards. I'm not too phased about making new intakes and exhausts to be fair, I've done it on my kit car and I'm always after a new learning experience I need to either tidy or redo the wiring loom as it's a bit messy at the moment, choice of ECU may depend on which route I take! hoopsontoast I can see where you are coming from, I've heard they can be a bit twitchy in stock form! Mine's been lowered and fitted with poly bushes and adjustable dampers, which seems to have helped a fair bit. Now I've gotten used to it I reckon it can take a power boost without getting twitchy, plus I'll continue to tweak the suspension

Have you asked on the Triumph Dolomite Club forum page as there are a lot of folk with experience of doing engine swaps?
