Twingo Adey's Twingo GT (F4R+T 2.0ltr engine swap)

just a side note as regards to driveshaft size and strength as someone asked on Cliosport so popping it here for future reference.

"only just got round to getting pics but gt shafts next to the 172 shafts I have here. GT one have the twisted spline ends. Not worried about them tbh"

Finished up the brake lines this eve, I HATE working with copper lines but they will do the job. Had to borrow the kit, must be 15 years since I've had to touch a flaring tool as I usually get someone else to do a neater job of running lines in for me. Slipped on some heat sleeving to maybe help keep things cooler. I will add more to the master cylinder itself once I finish up the reservoir side of things and i have the OEM heatshield to go back over the top. Unlike the Clio's the Twingo's downpipe runs in a very similar place to where the new one will need to go so has a nice factory heatshield to cover everything.

Might paint them lines black looking at the pics.

Hopefully, I don't want it too look too modified in there, more like a factory job if I can.
 
A good friend, well 2 sorted me out on a new fuel pump today and an Oil cooler for the Twingo.

I was gifted 3 spare pumps from his workshop .Checked them over and part numbers to get flow rates. 1st was a denso r35 gtr pump 145lph, 2nd a unisia jecs a42h24 which comes in at 190lph and 3rd a walbro GSS342 (255lph). All pretty much the same fitment. I tested the walbro and it jumped with 12v on so I decided to use that one. It didn't have a filter sock though so a quick call to @Jezer101 who dropped one of his spare pumps off so I could steal the sock off that 👍🏻. It needed a little fettle but pretty easy to fit in the housing. Replaced one of the electrical connectors and refitted it all into the car. With a 12v supply added it fills a Jerry can pretty quickly so hopefully its a good one. That said it is overkill, I've only used it as I've got it, a 255lph pump is plenty for 500+bhp!

Found some energy today so got the sump on, gearbox on and starter on and loomed up. Swung the crane out and got it back in the hole and loosely on its mounts. Next I'll get everything I can bolted up and see if it fits correctly, so shifter cables and driveshafts and ill look at the dogbone mount and downpipe. With swapping the MC I've been able to clear some more space back there but I will still probably have to make a new downpipe for it.

The 2.75 inch miltek downpipe only fucking fits! has clearance and space to wrap it, getting it in and out is tight as a nuns chuff though.

One driveshaft in perfectly the other side has the support bearing in the wrong place. Not sure how to sort that yet.... Will do some investigation.

Shift cables on and it feels like its shifting perfectly 👌

Also the clio 172 hose setup looks perfect, I can mod it a little to suit what I need. I'll likely use a 172 rad as its the same height as a twingo item, the meg rad is taller.

All in all a good and bad day but still further along than I was 😁👍🏻

I might also see if I can get hold of an evol dogbone mount in swap for my powerflex item. Its made of steel so I can chop and weld it to make a mount that fits.

I think I can use a clio 3/197 half shaft and I think I will need to shorten the out side part of the shaft to suit the narrower car.... anyone able to measure an inner shaft length from the edge of the block (gearbox mounting face) to the inside edge of the bearing please?
 
OK think its sussed just need to double check everything actually fits as its just an idea at the moment.

I need a longer inner shaft and shorter outer to keep the same overall length. The clio 3 inner defo looks longer. I measure that I need a 52mm longer inner and shorter outer.

The 172/182 outer shaft I have here looks nigh on 52mm shorter 😀

So just the inner to sort/source and that should be the right length. Its just making them mate up together which may be an issue....

Not only does the downpipe go in but it exits in the right place too. I didnt realise how similar the engine compartments were across the range.

I realised this with the 19 conversion. I think that the engine and gearbox mount datum points relative to positions such as diff axis, bellhousing face plane and certain volumetric reservations were established with the R19 diesel which I think was the first time a transverse FWD engine with hanging mounts was used. These data seem to have been carried across the whole range right up to and including the MK3 megane (don't know about the MK4)

I know right (y) the man like Brigsy has a miltek 2.75 inch front pipe in his stash for me too so sorting me out yet again. It should all being well be close to correct or at least useable to make something for mine (y)

Cheers man will take a look (y)
 
Engage super pikey mode, but in reality if it works........... take one rear dog mount and give it a slight curve to fit what you need. Tbh after doing it I cant actually see a problem with it. Only tweaked it over about 1.5inch.

Topped up the oil, connected the loom and ecu up and then.....a frustrating 20min where after connecting everything back up the starter wouldn't spin at all. Don't forget to fit the main earth lead (full on school boy error that one) Span over for a long while to make sure oil pressure was good. Then as the battery was getting low i brought over the VRS to give it some extra oomph.... No exhaust, no map (still on the efi parts 1.2 GT remap) and the bores full of oil where i got paranoid it would seize up after being sat around.

Im quite chuffed, I blame @Brigsy for getting his running and it made me jealous :D Still loads to do but the fact it starts and runs is a huge weight off my shoulders considering i kind of bought it blind (y)

So I slapped in some 172 hoses and piped it all to a crusty old 172 rad so I could see what would and wouldn't work. Starting to get tight in there now though. Ran it up for a good 30min but the temp wouldn't get above 86 degrees, would ge there then drop to high 70s and just cycle. I didn't want to rev it up for ages to get the fan to cut in as it sounds like the apocalypse. Anyone know what normal temp is on this engine?

Not much to see tbh. Now I need to get everything in nicely and on to some finishing work. Give me another month and we might be ready for a test drive 🤞🏻

Well at least its cooling it - better that than overheating. Maybe the stat is a bit shonky?

Is the interior fan on? If the heater is on it can hold the temp down, my XC90 wont reach running temp if I leave it on idle with the heaters on.

could be on to something there, i did have the fan at half chat to help it bleed through nicely.
 
Decent first start, engine sounds healthy enough. You still using 172 injectors/return pipe on fuel rail?

Temp sounds quite normal considering ambient temp is not too high, stat prob 89deg. Mine took ages to warm up on idle, fan did not cut in as did not get hot enough.
