small turbos and parts

[bmw2101]

i am considering, either turboing my 1.1 metro or making it bigger cc but 8v. I tihnk standard in 8v 1.4 is the only other option to my 1.1


Now i have also the idea that i could fit a small turbo. The metro turbo on the A series didnt have an intercooler. Do you really need one for a small engine under 90 bhp? I want it to look as un obvious as possible.


What turbo is good for m application also please? Someone elese i know of has done it and used a citroen van diesel turbo. 

thanks

Easy option might be the Renault 5 gt turbo setup. That's a 1.4L engine and you might even be able to use the carb of it.

You might get away with not using an intercooler if you run low boost but i would always advice to use one if there is room for it.

its on a single point injection system now, there is a lad on the metro forums who has done it already with this set up. He is using a standard ECU but turned up the fuel pressure, i have a speeduino ill use i think.


I think he said at 4psi he had 80 bhp which is more than enough for me, so no intercooler needed?

There is/was a company called Van Aaken Developments who did turbo kits for Fiat Cinquecento and Ford Ka, using Mondeo diesel turbos.

I have some scans of parts list etc somewhere.

Given the k-series is dimensionally identical from 1.1 to 1.8vvc is there a reason for not following that well trodden path other than “because…”? 🤣

What about a k turbo from a 75/ZT? Not sure about the fit as I only ever went from 8v to 16v 1.4 in my old rally car. Or for uber upgrade points how about a 2.5 v6 from a ZS? I know someone who’s swapped one into a ZR if that’s of any interest?

well, the main thing is its in the car now. So i know its good and not a headache before i turn the key. There is a quite a lot of 1.4 16v for sale, but i don't know how easy they are to fit. Also i think a small turbo 8v engine will give more torque than a 1.4 16v, probably something like the 1.8 though?

But the thing is, i like the idea of a metro turbo like the old ones where.


Any idea what turbo i should use?

I have speeduino ecu, and i am quite familure with wiring this stuff already as i have a rally car with a b230 volvo engine on microsquirt.


thanks
