Hi I have a 92 sierra that's a dohc efi. Basically the dohc has past it's best and it only gonna go down hill it got low comp on piston no.3 and needs a timing chain change. And to top that off my mt75 box is whining and crunches into second.

What I want to know is can I drop in a efi pinto and run it on the dohc's wiring and ecu. Why pinto u ask? Well I want to do a pinto turbo conversion and have a pinto turbo manifold from few years ago and want to run a low boost setup for a while . So I can save for some low comp pistons.

Any help would be great . Thanks

 

It should do no problem seen as they had Pintos natively, I am not sure about the if the box will bolt up though, Pintos used type 9 but it should be possible.

The Pinto if EFI, used basic management though, opposed to 'EEC' of the DOHC, if it's carb it will be easy.

I'm gonna use a type 9 box anyway but want to retain the efi as I wanna turbo it at some point

 

But obviously you can't just use your existing map, so you will need a remap at the very minimum.

The EFI Pinto used an air flow meter whereas the DOHC uses a MAP sensor so it will not be a straight swap. It may be possible to fit the sensors from the DOHC onto the Pinto but you'll need to check for things like the crank position sensor as I don't think the Pinto used one. Probably best to get an entire EFI Pinto setup and use that. Turbo Technics did a turbo kit for both the DOHC EFI and Pinto EFI.

 

pinto carb model no crank sensor works throw dizzy
i dont know what bhp you will have with the turbo but the type 9 is good for around 200bhp so maybe something to watch
