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

That's on 225 injectors, walbro 255 pump and a 4 bar external reg with a return to tank. I checked the ecu using torque and the poor thing was trying to pull 80% out on the short term fuel trim, probably maxed out. No real need to run it again before having a map on it now though unless checking the odd bit here or there. 30 min of running with no issues arising is a big thumbs up in my book :D Hopefully it holds up when i start giving it some.
 
I never had chance to see the short term fuel trim on mine when i had it running, cant imagine its too happy either as its a better flowing head, different inlet manifold and hotter cams.

Like yours it fired up and idled ok from the off though so the ecu is pretty capable of adapting to suit, and should be ok for low speed driving as i guess the ecu will correct the fuelling to lambda 1.0 off boost.
 


another little vid showing it idling with the cooling system lashed on, the ecu is trying to target 650rpm idle as that's what the stock GT ecu/engine runs at when warmed up.
 
Brakes and clutch lines finished off, for now I was able to refit the original reservoirs with a decent amount of clearance so have done that rather than relocate everything. I think the clutch and gearbox are working but without a driveshaft in I guess it would just spin up that sides output. Could check with a camera and mirror I guess (tomorrows job)

Gearbox filled with oil, that pisses out when there's no shaft in there 🤣🤦🏻

Borrowed some 172 HT leads and they work fine and allow the length for the coil pack to sit where its needed.

Looked at the boost pipework, the laguna boost pipe lines up lovely with the fmic and should do the job nicely, just need to trim a little of the fan shroud to give it some space.

Piped up the brake servos vacuum, used part laguna joined to the stock GT line and clamped it to the coil bracket.

Briefly I thought I may be able to use the twingos original header tank, would be amazing though the inlet manifold touches it, I'm tempted to see If I can maybe remould it a little to suit as it would be a way neater to have it beside the rad than the Clio one on a bracket above where the battery was.

Still plenty to do but another good day of progress.

It's all getting abit snug in there now. I trimmed the oem header tanks mounting points to shift it back 5mm but really it needs more. I will shave the webbing off that's close by and may try warming it up and reshaping it a little. Would be great if it works as it frees up space elsewhere. I also had a good look over the boost pipe on @Moggy's advice and found a very well hidden but big split. No big issue as if I use the oem header tank I cant fit it in as well so out with some spare pipes to rough out the boost pipe run. Will need one top pipe making but nowt major to overcome on the hot side.

Also started loose fitting the front end on to get a better idea of things. It all need to come back off when I replace the rad but it all fits quite well back there. A lot more cramped than the old 1149cc unit but not actually that bad.

I fitted the driveshaft in the other side and made sure the gearbox gave me some output. Notches into 5th which I'm not too happy about but the clutch also feels like it has some air in there so fingers crossed its not a total shitter 🤞🏻

Anyway have some more pictures, thanks for taking a look 👍🏻

Mate this is wicked, well played for the work and knowledge to attack it 👌🏻👌🏻 only joined in reading the thread from page 38 but wicked work.

As a reference my mk3 meg will sit around the low 80s water temp when driving steady in this sort of weather, so I'd say idling with no front end on the car, those numbers are right.

Looking forward to seeing this progress
 
Thank you @Sir jake the brit (y) no knowledge here, pure guesswork and bodgineering :D



well maybe a little bit of research but Renault make a lot of it easyish you just need to find the right combo of parts (y)
Very modest! Either way, wicked build. You just running stock power and an open diff?
What wheels and tyres will be on? (I understand all this was possibly laid on on page 18 or something!)

It's going to be a right little monster!
 
im aiming for 250bhp if it will make it. Yeah open diff on the 5 speed diesel box with some 195 50 15s 😂

Though to be fair ive ran 240bhp in a 172 turbo and 280bhp in a sc 172 on the same size tyres with little issue, I wasn't on toyos back then though so something sticky and maybe a touch wider will probably get added in the future (y)

Hahaaa wicked, will be a wheelspin monster 🥖🇫🇷🥐 I had a 197 which we boosted and that was about 250 on 215. Was fine on the road, track needed a diff. But was fine 95% of the time.
