Right, I'm fed up forgetting and then having to look up all the details all over again, so can you out there help me compile a list?

What variations are there of the 2.3 redblock engine? What EFI systems do these run, what cars do they come in and what power do they put out?

James/Mac are probably the men for this, but any input appreciated!!

Cheers

Carl

Good idea. How about also some info on how much modification each variant needs to fit a 360? That'd help me a lot.
Ta.

There's a pretty good resource Here

1. you need to use oil sump and pump from 360...
2. you must choose the right one...(redblock, imean)
3. all other changes can be done by commitment present...

Cheers Ronnie, thats a good link.

So, assuming I was keeping the original EFI, if I wanted to put a 2.3 redblock in my 360 I'd really want a B23E, from an early 240? Probably not the most common of things, so maybe a B230E from a mid 80s 240 would be better?

I've got all the engine bits sorted, I'm just trying to decide what to do with them, but it's gotta be on the cheap!

It would be tempting to go for a B234 - but unless you leave it stock, that's going to cost BIG money. I've heard talk on Turbobricks of $10k to rebuild properly inc. adding turbos etc.

I will be looking for a B230FT in the nearish future, and will make a full engine rebuild before transplant. It's easy to spend up to £2000 just doing that once you factor in engineering services to mill faces, regrind cranks, balancing and head work. Then there's bearings, pistons, gaskets, cams, followers and other head components, Turbo Rebuild, injectors, uprated ignition and a few extra tools I'll inevitably use. I see it as a medium term project to be completed as time and money alows. I still don't know about fuel management, will worry about that later. Either stock or MS with water injection - I don't like carbs

Once done I'll have an engine better than brand new that will last longer than the 360. Or at least that's the plan. It's as much an educational project for myself as anything else since I've never approached anything like this before.

B234 is the eventual plan, but just in stock n/a form. Will probably just involve getting a donor car and swapping everything over. Just haven't got the money to do that for now, so I'm just going to experiment with the B230s

I know what you mean about rebuilding it Aaron, my plan is to do a bit before I drop the engine it, then I'll have bought the stands and lift, so it won't be so much of a hassle next time. And if I keep Fake running, I'll always have a driver!

Mornin' all, been doing a little digging - I think I've got most of them.

Not all were available in the UK but turned up in Europe over the years.

Different sources sometimes give slightly differing outputs but this gives
an idea of what's out there.

Good info guys. I'm sure I read on here that the early 230s had 9mm conrods, which were a bit weaker than desirable. Then later they switched to 13/14mm IIRC. Also I think the heads for the 204 and 234 were designed by cosworth, the shameless harlots who'll snuggle up to any car maker as long as they're paying
Seeking out a donor car for a swap is a minefield, given these endless variations. Does anyone know which cars had the B204s and B234s? If I can't get one of those, i'll be after whichever of the 230s is durable enough to last ages putting out 200hp.

B204 was Italian and French only I believe, and rare in those markets too.

B234 can be found in 740's and 940's '89-'92. Don't know which trim specs are more likely to have them.

That's excelleent Mac, exactly what I was after! Thank you.

Anyone know what the K Jetronic system is like? Would I be foolish to install that to a 360? Would it be better just to go for the more modern LH2.4? In my eyes, if it's up to the job, the K-Jet system would probably be easier to install and more importantly cheaper to get hold of.

Yeah B2x0-series from 85 to 89 has weaker con rods, buy 90+ engine to be safe (some 89 models have had stronger rods too but it varies) or a B23 series engine, which has allmost always strong "M-Rods." (Some early B2x OHC series engines have weaker rods than later models, but stronger rods came in somewhere late 70's)

Weaker rods will handle about 250hp in a turbo engine in normal street use. In racing you can snap them much earlier..

K-Jetronic is a mechanical injection, when everything is in order it is a reliable system and works good. But if parts are worn it can cause some trouble. But basically when everything is in order it is a solid system.

There's a one more engine spec document, not everything is 100% accurate in that one either but it is pretty good. http://koti.mbnet.fi/mtn/Engine%20classification.doc

K jet injectors are mounted in the head not on the manifold like the electronic injection engines. If you want to use K jet then you will need the metering head complete and the cylinder head off the engine.

If and when I feel the need to do this, then it would probably involve getting a cheap donor car to transfer everything over from. For now I'm gonna be experimenting with the B230 I got from you Dai
