hello all,
could anyone tell me if a 2.3 16v engine will fit into a sierra mk1 and how much modification is needed. i want to run it as a daily. i have complete 2.0 dohc with all running gear set ups (manual) here and wondered if the 2.3 would bolt up. i know the 2.0 16v will do the job.
any help advice or advice would be appreciated.

Get a 2.3 from a Scorpio as it's already rwd

Anything will fit in anything with enough work.

By 2.3 I assume you mean the one from the Galaxy?

Probably means the one from the bug eyed scorpio.

And if so, its pretty much a 16v version of the 2.0 8v twincam found in late sierras

Correct.

Another mod is to fit the head onto a 2L.

it is from a galaxy. what else will i need off it to convert. if the head fits on the 2.0 8v engine surely easier conversion. thanks for all info.

The 2.3 has balance shafts in it too. I guess it would be an idea to remove these. I've a 2.3 galaxy which is a cracking engine as long as its well serviced.

I thought it was a chew on to fit the 2.3 head to the 2ltr bottom end???

just tap the holes that you need to tap to take the rwd engine mounts, there are some differences but it's essentially the same engine turned sideways

remove sump, remove balancer shafts, fit blanking plug to stop oil supply to the balancer shafts, refit dohc sump

compression ratio goes up to 11.1:1 rather than the dohc's 10.3 or 9.8 depending on which engine you are using

you just need to make sure you've got a flywheel that will fit with the manal conversion as the clutch is way way different, i've got one int he garage somewhere i might be able to take a picte of

so basically i can use the head on the 2.0 engines i already have. job done. just rewire and should be ok. am i right about that. i have 2 x 16v heads and 2 x 2.0 engines with dohc 8v heads.

So do the heads go straight on the Dojj.

the heads will swap over no issues

but the compression ratios will be all over the place

with the 2.0 8v head on the 2.3 bottom end the compression ratio will be too high

and the 2.3 16v head on the 2.0 bottom end you may have issues with the bore being bigger and the seal not working properly in the head gasket fire ring

nothing is ever simple is it.

not really you could have a copper head gasket made by farriday engineering thicker than standard which would reduce comp ratio.

Just an idea.

If you have a current working dohc Sierra lump in there you can slot the 2.3 in and all you need to do is sort some wires out to shirt the coil packs out and you tweak the fueling and job done

your forgetting 1 major thing, the galaxy 2.3 heads thermostat housing will be in the way! you need a 2.3 scorpio head as theres no thermostat housing at the back of the head

galaxy head has both side and rear waterways, rs cams, 8v sump and pickup, youll need 2 block of a part on the block when removing the balencer chain, rs flywheel and clutch is a bolt on fit aswell,
just done me own 2.3 on a twinchoke carbbie
