Engine transplant
« on: June 18, 2017, 22:15:44 PM »
Hi,

Not sure if I should list this here or the tech forum but I am contemplating switch my SE6's 8v for an ecotech, how easy is this and should I consider something else?

Being completely non mechanically minded what's involved in that if I source an ecotech engine, gearbox and ecu, what's the difference in wiring loom?  I think from memory the same loom was used across most Calibra's but may have that wrong and it could be my memory failing me again!

Any help would be appreciated?

Engine transplants are actually simpler than they sound, if you are competent with a set of spanners and can apply some common sense.  Where you will get caught up will be making sure all the parts you have are compatible with each other, hopefully someone on here will have done an 8v to ecotec swap.

Just remember there are a few tools usually required, so if you dont have a good socket set and other useful tools (jack, engine crane, axle standards etc) or you cant source them then the price for tools can be quite high.

Thanks, I was hoping that the fact the engines were all standard options and the cost savings re wiring looms all being the same would see the same ones used by the manufacturer across the range and probably the cavalier of that age too.

I'm going to ask probably the LEAST helpful question here but why are you swapping from the 8v to the ecotec especially?

I'd offer a little help though in suggesting getting some mechanically minded mates over to help you the first time. I could barely turn a spanner until Dan and Andy and Wayne (and many others) took on my Saab engine conversion, nowadays I've done a few cambelts etc and tinker readily. Even brought a scrapper back from the brink last year!

Gearbox could stay I reckon, not sure on the loom <-> ECU myself. Might be good to do the clutch too while it's all off.

MarkB,

Don't do it..!!  :o It's an SE6 so like any SE model, they're pretty rare. I know that (a) that doesn't mean much as "its only a calibra", and (b) I'm "a stick in the mud old fart" but as a fellow SE6 owner, and an auto SE6 at that, I'd suggest leaving that swap alone.

Enjoy the car as it is  :)

Hi,

Thanks for responding, to be honest I find the 8v uninspiring as it doesn't seem to have go in it and I had an eco tech before and that wasn't too bad.  My thoughts for choosing an eco tech were that as it was a standard fit item it would be relatively simple too do.

I also had in my mind that vauxhall used the same loom across the model range and life so was hoping for an element of plug and play.  I haven't decided either way yet as have some more stuff to do first such as checking out the underside on a ramp and fixing the now broken sunroof before anything else.

Hope that answers my thought process and hope.i am not too misguided.

Marks,

You have to do as you see fit and what is best for you.

I agree the engine is gutless: it has 115bhp when it left the factual it won't win any races. Perhaps there is some bits that can bedone to bump up engine power? That could be worth investigating? It may be easier than an engine swap. Who knows?

Now if you could go find a Red Top, that would be interesting indeed. But I like to keep things as original as I can  :)

You have to choose what is best for you. I have the 2.0 ecotech and I love it. It has lots of power and makes a nice sound on standard exhaust.
I agree with Will's point about originality but at the end of the day you have to drive the car and if  you think it would make it more enjoyable then go for it  ;)
I think the ecotec is a good balance, gives great economy and compared to many of the cars of that age has pretty good performance too.

A Saab B204x turbo engine fits* (ask me how I know) and uses† the same boxes. And some of the loom!

Allegedly you can turbo the C20NE too but I gave up on that, having researched and researched. Wasn't as cost-effective tbh as the Saab engine swap (*could* have been!)

*Mounts up perfect, bonnet even shuts after soundproofing goes!
† Uses up.

Hi,

I like to keep my cars original where possible and was just seeing what others had done.  I may go down the route of old school first I.e. upgrade the air filter , exhaust and leads to see if that makes a difference.

I am surprised by the current performance as I thought this was the same engine as the cavalier sri 130.

I agree a redtop would be fun but of all the calibra's I have owned (this is no. 4) my v6 was the most enjoyable.  Wish I had kept the engine now.

Hi,

I run a V6. The 8V Vauxhall engine of that era was utterly reliable if serviced correctly - I knew of one that did 400k! The RedTop is also pretty good and IMHO a far better engine than the EcoTech. I have had two EcoTechs fail on me and would not want another. A couple of years ago I saw the B204 conversion and it does work well.  There is a well documented V6 into a 4 pot on here but it is a lot of work...

Ive had a retop....very nice engine...bit of a legend now....I have also had a Ecotek auto....more power then the 8v....but the last 2 calibras have been 8v`s.....low down touque is nice...but not that quick....I agree  with Wills though...8v`s will go on forever when looked after...my old one had been to the moon and back..200,000k

Somewhere in darkest Bedfordshire, DanSE4 drops a glass of Rioja. His PTSD of the 8v/v6 causes his hand to tremble. The horror...

Dan's v6 SE4 though does run super, a real testament to just how far a proper nutty swap can go.

Fair play to you though if you want to keep it original. I put a C20SEH head and cam on my C20NE along with filter, leads and 4-2-1 manifold and it made a bit of difference... must say though once I've got a little more experience under my belt I'd totally do the Saab swap again. That was a game-changer.

What engine does the b204 come out of?

I am not looking for something that breaks the sound barrier as we have got more and more of those average speed cameras near me now but I want to be able to move away at roundabouts etc with a little more go.

Serious error here! Dan drinks lager!  :) I believe Mrs Dan may enjoy a glass of Chardonnay...

Back to the original thread. The B204 is a Saab engine who Vauxhall used to own...
