F4RT Powered Alien

Got the shafts back today, happy with the service and they are spot on.

Managed to pick up some other parts that I needed, headlights etc just to finish it off. Need to paint rear bumper and hopefully the colour match won't be too far off

Looking good. Never attempted a fwd engine conversion but completed a rwd one.
Keep up the good work.

Built the shafts back up and then got them fitted in, bolted the whole subframe and wishbones all back together and got the car on the ground finally!

Need to have a tidy up in the yard so I can make room to get it down onto the ramp for the final stages. Hopefully won't be much longer!

Thnx for the update!

Solid engine mount, can't complain for £50. Definitely be needed for this.

Made up a tray for the ecu to sit on, looks as if the battery will have to go in the boot, be a simple enough job though

The bumper fits without having the cut the grille out! Happy with this as every twingo I see with a aftermarket intercooler always cuts the bumper apart. Secured the coolant bottle in its final place too.

Engine bay is all but done now, bar an air filter which I'm waiting for to be delivered. Managed to keep the battery in the bay, which I prefer the look of if I'm honest.

Should hopefully get the car on the ramp next weekend.

Pretty much the final engine bay shot, minus scuttle trim and wipers

Really cool build! should be some machine when it's done. really like the way it still looks subtle, will definately surprise a few people!

Put all the scuttle trim on and fitted new cone air filter earlier today. Freshened up the ecu holder and made a support bracket.

Being held up by the hazard lights being stuck on constantly though, thought it would be a simple job. But after swapping parts with my other twingo I’m still no closer to fixing it. Narrowed it down to a wiring fault I believe though.

Also managed to find this cool picture of when it was in the paintshop

So after messing around with near enough the whole interior loom today and various switches the hazard lights have stopped! So all the interior is now back in place and bolted in.

This is taking a lot longer than I had originally hoped but should get on the ramp soon enough

Love this thread youve done an awesome job.

So finally got the car out of the back room on Friday night! Got it on the ramp late Saturday morning, and the work began!



Made a dogbone up finally! Using the original mounting point on the subframe and the original point on the engine block. Will need to press in new bushes most likely as they were slightly worn. But it holds the engine in a perfect spot.

Picked up an exhaust system for a 225 in 2.75” bore. After I put this up to the car it wouldn’t fit through the subframe gap. Exhaust will be 2.75” turbo back.

Had to bring it back down and get the grinder back out.

Took some more out the subframe and then welded a patch back in, link pipe now fits perfectly in the gap. Also sorted the gear linkages, they’re slightly too long as you’d expect but they work perfect still.

So after this I filled the gearbox up with OE ELF oil (75-80) and then bolted all the subframe up, wishbones, anti roll bar etc.

Had to modify the passenger link rod between the wishbone and chassis as the gearbox is wider. Filled up the cooling system and bled it through.

Ran the car up to temperature and the fan cut in just when it should’ve. Pulling cold air through the radiator into the engine bay.

I actually drove the car out of the workshop and around the forecourt! So it moves ha.

Also fitted a new genuine cup spoiler




Fitted the wing mirrors, but need to paint them black. Got the fog light surrounds and bumper badge but need to paint them black also.

Upgraded fuel pump fitted to the tank, took the chance to clean it all out too. Car still runs, just massively lumpy now as it has no idea as regards to fueling.

Rear bumper is in primer ready for paint. Ran a cold air feed just into the engine bay, most likely join it to the front fog light surround.

We now have a matching rear bumper!

Nice, Coming together

Surprised you didn't go otherwise a specialist components plug and play ECU, the one on my Clio works really well.

Looks like it's going to be very rapid.

To be honest I did look into them but the prices were quite expensive. Trying to keep costs down where I can, and I’ve even done away with the AEM unit for now. Chris at EFI said he’d like to try on standard ECU. Hopefully it doesn’t restrain anything and it goes well.

Wanted to keep the whole car looking as ‘out the factory’ as possible really

They are dear but imo standalone is worth it because you can run wideband which is obviously fairly crucial on a fairly strained engine.

Ran my 172 itbs on a standard ecu for a bit (basically just to prove Chip wrong) and it ran ok but imo standalone does a better job. I think unless you spend a lot of time getting the map right on part throttle etc a standard ecu is a better proposition. Considering who you have mapping I'd be happier with a standard ecu, I've driven a lot of Scoff's maps in the past and although his full throttle mapping is spot on and safe I don't think he does any road mapping or part throttle drivability mapping, it's more drag racing focussed as you would expect from someone who mainly does work specifically for drag racing.

Looked at Omex, sybele and a few others. But after he said try standard I thought yeah why not. Hopefully the driveability of the car isn’t affect too much and it’s still good throttle response etc. Hopefully be mapped this side of Christmas if I pull my finger out and Chris can fit it in!

I'm pretty sure the twingo and meg share an ecu with just a few different pins, should be a case of loading meg calibrations and map and driving off!
