the Duratec SVT's would be nice, even a 2.0 Zetec form Focus would be nice .......have a Focus with 160K on it, the car has given me headaches, but engine/trans has been rock solid......

Dear Marcos Group:

I have a TVR 2500M with that great bid heavy and underpowered Triumph TR6 engine. I have daydreamed about engine transplants for a while now:

My list includes:

Mustang / Merkur Turbo I4
Ford Zetec SVT
Ford Duratec I4 DOHC and all aluminum. Came in 2001 and later Ford Rangers, some mazda's etc etc
Ford Duratec 2.5L V6 Contour SVT all aluminum block and heads, porsche designed cosworth reworked.... .
VW VR6
Audi 7a 2.3 L I5 DOHC, cast iron block, alum head.
Audi AAN 2.3L DOHC Turbo 227 hps show room stock hot to 500 without too much grief......
Nissan 20SRT 2.0L DOHV turbo
Toyota AE86 2.0L DOHC


Regards
Robin

The engine in your car was straight from a Mk2 Cortina saloon and is essentially the same as the engine used for many years in Formula Ford race cars. Try taking the plugs out, squirt a little lubricant into the plug holes and try to see if it will turn over. If it does chances are it will be possible to get it running. Make sure you get let the lubricant disperse before putting the plugs back in or you will get a hydraulic lock.

If you go here http://www.burtonpo wer.com/technica l_1/kent_ crossflow. aspx you can see much information about tuning this engine. Any tuning you do to the original engine will not reduce the value of the car and may well enhance it.

A lot of the later Ford 4 cylinder engines had the same mounting holes on the back of the block so using one of these is a simple task compared to fitting a V8 or other make of engine. The Marcos should have come with either a Lotus Twin Cam or the Ford Cosworth BDA but of course they cost more and were less suitable for everyday use.

You could even fit a Ford RS500 turbo motor but that would be more difficult due to needing to locate all the ancillaries - but another option would be to look for a Cosworth YBM which was used here for Midget racing for some time and is popular with Vintage racers. It is the Cosworth turbo motor modified to be normally aspirated with a pair of Weber carbs.

I hope that gives you a few ideas. I used to race a 1500 and also a 1600 in the UK when they were new cars.

Regards

Roger

thanks for the insight. I have inherited a 1600, but it hasn't run since 1979. THe engine is said to be "good", but it has been sitting since then, so who knows what it will take to get it back up.

I was actually considering getting the engine running, but wanted something with more "omph" (it has Ford 4). I do not know what to do to give it more power without ruining value and ease of maintainence. I really can't do a lot of work myself, and want to make servicing it simple, and have it be as reliable as possible....

The car "looks" fast to me, but it would also be nice if it sounded and went as fast as it looks! I guess I do not want to be blwon away by 4 cylinder Accords and V-6 Camerys..... ..

The Rover V8 was based on a Buick engine with alloy block and was particularly light in weight for a V8. I seem to recall that when fitted to the MGB it was no heavier than the 1800 MGB engine. The V8 engines you mention would be much heavier units and while anything is possible I would think that there are plenty of modern 2 litre engines around that would be far more suitable if you want it as a reliable car to use. If you look at other cars when they get old and collectible, the value is always in the ones that have original motors so you might want to think about that too. There are plenty of ways to make either the 1600 crossflow Ford or the 1800 Volvo engine more powerful.

Best of luck!

Read some old Wiki articles saying certain engines made the 1600/1800GT a bit nose heavy (perhaps iron block engine). As later Marcos had Rover 8 cylinder, did this make it evebn worse---or were Rover 8 cylinder cars not the same as 1600/1800?
I bring up these questions because I wondered if anyone had a experience or thoughts on placing a Ford or Chevy V-8 into a 1600/1800GT (something like a 289/302 Ford or a 305/350 Chevy). Would these engines make the car too nose heavy and ruin the handling?

I was dreaming about a way to make the 1600/1800 GT more powerful, sound great, have a modern engine anyone can work on....but not at the expense of handling.... .

Figured some MArcos had Ford as well as GM engines, so thsi idea shouldn't be too blasphamous :)
