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

Not sure what you mean, the cars standard turbo is a td02/td025. The bigger turbo setup ive partially built is a TF035 12T. I only have an actuator, oil feed and downpipe to make and it can go on.

I didnt know if it had a variant number. Like TD02 - 10T or anything.
 
not that i have found as of yet. That seems to be the full serial number. A turbo company did offer to look at it but said the making the rear bigger might be tricky and the shafts might be quite small and adding bigger wheels to it might cause them damage

I had a little play with @Jezer101 in his mildly modified 172 whilst in mexico. In a straight line theres not much in it but the 172 is a bit quicker, especially when above 100. I think and he can correct me if i am wrong but his has a mapped ecu, 182 manifold and decat in place so probably has the full 172 bhp 😁


So i will now look at getting the bigger turbo bits ordered so i can work on getting it fitted up purely as most of it is here. Im still thinking about sending a standard turbo out for a quotation on making it a hybrid but with the size of it id still expect it to deliver boost low down rather than higher up in the revs where i want it, any suggestions?

After weighing in the oem172 16s and yours being partly stripped you have a weight advantage. But my 172 feels strong. So i reckon yours is more than 150bhp with your post mapping mods.
 
its only the rear seats out now, everything else has been refitted as it was too noisy
 
I remember looking at the Turbo on my GT and it was comically small. I think it's the smallest unit I have seen on a production car.

Pretty sure the downpipe is a similar size to a Macdonalds thick shake straw.
 
indeed I've not seen bigger, ot does well for its size mind, just wants to deliver it all down low and not much up top, perfect for it's original design of a small town car. even the after market down pipe is only 2 inches which says alot. I will try and knock up a 2.5 inch downpipe for the new turbo. It doesn't have to make more torque I just need it to make the same I already have higher in the rpm.
 
I'm sure I will find the limits at some point...... be nice if it will do a solid 170bhp though. Holding the same peak torque 1000rpm higher than now will do that, but I need the engine to rev a little more, I dont doubt the bottom end can do it revs wise it's the cam that worries me at the moment.
