After another long absence i'm back again. No update on my green mk.2 estate yet other than i cut the boot floor out of it ready for the new one to go in.
Anyway, I've been away as i've had my head stuck in rebuilding an Mitsi Evo 2 for some racing next year and its soaked up my time and all i've had to spend plus some over the last year and a bit.
As its now getting to the time of year that she'll be resting up in the garage, so its time to get back to the Triumph so that I can try and get her on the road for the 2008 shows. I missed them all last year and that really sucked a fat one.
Funds (or lack of them) are swerving me away from building the blown small block chevy i had been planning as the cost of bits for the engine would be around the £2k mark so i got to thinking about selling the blower and the sbc bits i have and trying another route.
How about a 3ltr turbo six from a manual mk.3 supra? I should be able to get a car to break for £500, sell a few bits, keep the engine, box etc etc and end up with an engine that "might" be easier to fit in the triumph's engine bay than the V8 which would be a squeeze given the current Rover V8 engine thats in there.
How much of a job would it be to get the supra motor running on the original ECU if i dropped it into the Triumph? I suppose a megasquirt would also be an option if that wasn't possible.

Triumph Estate to do list:
1. Remove Rover V8 - done
2. chop, weld, spray - ongoing, need motivation
3. drop in RB25
4. burn rubber

I know nothing about how to do this but, I'm loving the sound of it! Fitting should be OK in theory as the Triumph originally had a straight six, I'm assuming the Supra is a straight six and not a V  |

Supra engine is a straight six and as std give around 234bhp manual box is good and strong BUT the bottom of the engine can let go easily when you find a donor get the engine hot and hold it at 2000 to 2500 rpm in nuetral the big ends always rattle if they have play in the t that speed, yu can replace the shells but its extra expense , wireing is reasonably easy with original ecu if you start with complete loom and just connect the bits you need start with all the earths first and there is a lot of them!! megasquirt would prob be easier but mlre expensive again¬¬

Would definitely be interested in this one if you go this route. My MK1 2000 has spat the dummy out and looks like I'll be searching for an alternative. Was warned off the Supra lump because of the tendency to spin the big-ends from a drift luvvin friend. BMW lumps are good to go, but heavier than original apparently and make the car even more nose heavy...... Chris W is the main man for these - or try www.monarch-stags.co.uk/index.html - as they do BMW rear swaps etc... if you're looking at an easier route than fab'ing a complete rear chassis set-up. I'll be watching this to see which way you go fella - best of........ John |

I just saw Aberdeen as a location and ignored the rest of the post. I know that's naughty, but....
Persley scrappies, also known as Stan's. Across from Danestone Tesco. Recently chock full of big old RWD crocks.
Also very cheap. I doubt Stan would sting you more than a ton for a 325i motor, 'box, loom and the rest. Between me and my neighbour we've had countless forty quid engines from there. Depends how much of a regular you are - and how honest you are when filling your pockets...

A BMW six might just do it. I would prefer the 3.5 big six rather than the 2.5 but i'll maybe take a trip to Persley scrappies on saturday. Hey its better than christmas shopping isn't it?
How much does the triumph six weigh? any ideas anyone? its a fair old lump so would be surprised if the small BMW six weighs more. The big six wouldn't be as much as the small block Chevy so the handling wouldn't be as bad as it would be in full hotrod guise.
As it happens, i'm looking at BMW suspension and brakes for it anyway so it might be a better idea to look for an E20 325i or E28/E34 525i.
If its got not turbo though, i'll be forced to fit nitrous I hope you realise.

Anything over 200BHP and about 220-250ft.lb (depending on health) will strain the already frail rear end on a big Triumph saloon - so looking at one of the Monarch kits, or fettling your own BMW conversion, is well worth the time and investment if you want a useable car - if you're looking to handle that kind of output in a useful manner. Monaro rear end is one suitable conversion, good for about 600BHP. |

Hi matey - I'll make the trip to the land of £100 BMW sixes please! ;D On the power / weight etc.... Power - Lewis is right - no-one who knows the Triumph saloon would recommend going above 200hp as the diff nose is a known weak point, on top of that you have the frail splined shafts and UJ's. So a BMW rear end is the best option for uprated all roundness ( hope that makes sense! ) Weight of motor - it's not the actual weight as far as I was told - it's more the dimensions. The BMW lump would sit further forward due to it's length unless tunnel and bulkhead mods were done. The V8 'should' be shorter and therefore more central. Again - Chris Witor is the main man for this type of info and I've only done some general asking around. He probably can give a shed more advice than I've even thought to ask. Keep me posted on which way you opt....... notes can be compared!  |

on the weight of the engine - I'll dig it out of the manuals at home. Should remember!  |

I've already lined up some BMW 3 and 5 series rear end bits from a friend. I plan on fitting the diff, rear arms and hub/brakes from the BMW.
The plan was to go this way as the original planned Chevy V8 would be churning out 300 ish bhp with 350 plus ftlbs torque.
The issues with a V8 are the width though, any decent exhaust manifolds are going to need to come forward then down (tvr-esque) or i'll have to hack away some bodywork around the rear of the inner wings.
I liked the idea of the V8 for noise but the width issues could be a problem as the bay is narrow and the steering column is already a problem with the rover V8.
The straight six would be easier and as long as it wasn't a monster surely wouldn't be as long as the original six pot boat anchor. of course, the chevy engine is a heavy old lump so anything i fit would be lighter than it. My car has never had the six fitted to it in my possession so i can't compare anything to the original power plant.

I had the rear end from my mates M3 sitting ready to go in but it was half-inched from the storage I had  Will definitely be going along the BMW into 60's 2000 but it's wayyyyy down the project list at the moment. I'll be watching this one - Readers Ride thread is obligitory! |
