Turbo technics pinto conversions, any good ? I'm looking to start collecting bits up ready to increase my pintos power

Currently running mega jolt and twin 40's any suggestions?

Upgrade to megasquirt

Gut the 40's and fit a TPS

Injector bungs into the inlet manifold

Sort out a turbo and mount

Build a plenum and duct in via an intercooler

Rolling road to finish.....


Or

keep the 40's and modify to suit turbo application

rising rate fuel regulator

Sort out a turbo and mount

Build a plenum and duct in via an intercooler

Rolling road to finish.....


£££ better off with a more modern engine

I did have a 3.9 range rover with a turbo techniques conversion, it was a quality bit of kit

Tig welded manifold, CNC milled heads and piggy back ECU when on boost, so if you go this way I expect it should be pretty good

Turbo technics stuff is very low tech, especially the pinto conversions which are 25-odd years old now. I don't think they were intercooled and you'll end up only running very low boost. Sorting the fuelling out on carbed turbo conversions is a nightmare (you'll not get many chances to get it right before the pistons melt!), you're far better off running injection and a wideband lambda sensor if you are going the turbo route.

If you are keen on doing it I'd suggest the DIY option, pick up a turbo from a Volvo T5 or similar on ebay, make a manifold from steam pipe and upgrade to megasquirt to provide the management side of things. Add an intercooler and a pinto EFI manifold, scrounge a fuel pump and some injectors from a scrapped Saab turbo and you'll be looking at 220bhp quite easily. You'll learn an awful lot about how engines work and how they are mapped too, which for me was all part of the enjoyment. Mine goes well now, too!

I think I'll be down at Lydden for a trackday on Sat (as long as the weather isn't foul!) If you happen to be local, come along and I'll show you my zetec turbo conversion and talk you through the process.
