Default Experience using 2.0 DOHC sierra

Searching for a donor car locally and have been offered a 2.0 DOHC sierra. Can anyone offer advice on using these as donors please. Believe its injection and that the standard manifold wont fit under a bonnet?
Only thing I know of and All new to me so any help or advice would be great. Also what gearbox do these use?
Thanks,
Doug.

I'm doing the carbed version & its a MT75 box, sure the injection is the same.

The inlet manifold can be modded I'm sure!

good luck

most likely mt75.
I think someone on the forum was thinking of selling modified manifolds to suit

All DOHCs have the MT-75 tranny. It's a useable donor, the engine is quite big, but useable. If the injection manifold doesn't fit you'll have an option of going the bike carbs + Megajolt route. But better yet ditch the twink and get a Zetec. Most importantly, you'll get all the drivetrain and suspension bits you'll need.

Cheers. Zetec is where Id like to end up, but focusing mainly on getting the IVA and going from there really. Got to keep things cheap enough to afford the kit in the first place but still have a nice set up for now.

My build uses a DOHC and MT75. It's a huge engine and requires a fair bit of work to make it fit but it is a very good engine. I have modified my manifold but still need to make a custom bonnet to clear the cam covers and fuel regulator. You can read all about it at www.deepfolly.co.uk, there are loads of pictures on there.
Enoch.

Thanks. I have seen and had a flick through your site, now saved as a favourite and will read the whole lot later on.
Went to see the sierra today, bought it and by the time I got home the chap was unloading it on my drive Oh and my Haynes book arrived today too!

Hopefully I'm going to pull my DOHC on the weekend and shoehorn it into my chassis, once complete I'll take a pic and post it up, it will have the mod'd efi fitted then
