Just a quick post, this engine is often perceived as pricey to install, which I will accept can be the case if "done right"......

but, thought I would just relate the case history of the latest engine I have in which is actually going in my brother's manta.

We paid £200 for an MOT'd (but about to fail on the cat and brake pipes) Cavalier SRI 16v (one of the last ones with XE engine before they went ecotec)

Sold the gearbox for £60

Took off other random bits and bobs which were easy and quick to remove, these are fetching £45 as of last night on ebay.

Sold the brake calipers to a mantaclub member for £25


Weighed the rest of the car in and got £55

Engine with full injection/ignition system etc now stands us in for - £35, but ebay bits may fetch more yet.

So we have a good, running, test driven, Coscast headed XE 16v engine for a small credit of £35 which may increase!

With megasquirt, plus a set of bike throttle bodies on a diy manifold, and the std dizzyless ignition attached to the engine, you will therefore be able to have 200hp for around £250 total expenditure.....................................................

who said bike power/zetecs were cheap???????????????????????????????????????

That sounds great Nat. Well done. I guess its the bell housing and exhaust system that then puts people off a bit in terms of cost. But even if these are £600, a reliable 200bhp for around £850 is very tempting.

Its a shame you spent so much buying the donor!!!!! I guess you could always get another and almost end up with the injection system for nowt as well.

Now thats what I call 'locost'

Well done.

Cheers

I thought the COSCAST heads were only found on the early GTE's not on the later models? I really like the look of the XE - makes fantastic power stright out of the box, with loads of tuning potential. Only downside are all of the 'extras' needed for an install (sump, manifold, exhaust, anti oil surge modification, crank sensor etc). I appreciate most of these bits will be needed regardless of engine choice, but something like a Zetec is a much more available option!?

Only problem with a 7 is you need to find a bell housing to fit a type 9 or use a manta gearbox. Not sure if there are any complications using the manta box, but a bell housing will probably set you back a bit.

I am seriously considering this engine though as a winter project.

Are second hand bell housings easy to pick up, i would rather stick with a type 9 then it means i can keep my prop too.

Also how much does it weigh, i know it comes up alot and with near 200bhp it doesnt matter much, but its more for handling than anything. After having a big boat anchor in the front i think it will feel alot better with something lighter.

There was someone on here who put a K in his Indy and said it transformed it, even though it was less power than he was running before.

Regarding the CosCast head, how do you tell which ones are which?

Is it all down to part numbers or are there other distinguishing features.

Cheers

two really noticeable features (shown in Ned's website actually as well) are that the coscast one has no coreplug on the dizzy end of the head (the gm head does) and instead has a large casting rib there (the gm head doesn't)

secondly the coscast head says "coscast" on a spare bit of the unmachined head face underneath and just behind the exhaust manifold flange.

ps if you do get an engine and need a 8v steel sump I have one, plus should be able to find you a pickup pipe to help, as its easier to make one modded one using two "donor" ones!

ps ps for sump gaskets use either later ecotec or earlier setup from "sri 130" models fitted with the "20 SEH" engine (130 hp 8 valve 2.0) these both use a rubber wraparound gasket that fits round the std windage tray, much neater than the double cork setup used on the XE which always seems to get overtightened and leak.

Jesus, my memory is bad...

I never got back to you from THIS thread


I'm in the southwest so pickup is not an option unfortunately. If you can give me a price all in delivered for the 8v and a pickup(s) if you have any I'll get some money off to you.

Failing that I should be at westpoint November.

ahh, got them too, but just chop the flange off and use that, pipes are a bit small on the manifold, but for a start I guess they are ok!

If only I could do the same, it costs me about £40 to get rid of shells and even that's a struggle, everyone I call around here to take it whinges about me being too far, and 'it'll only weigh in for a tenner' Do you have a HIAB to play with or do you cut them up into wee bits and sling them in a van?
