Any sump consideration, irrespective of engine, will depend on where the engine sits in the engine bay.
Has anyone put a Zetec or a Duratec in a BMW before? That could answer some questions.

very much the same as the escort, the volvo b230 fits the escort and fits the bmw with the standard sump, its on teh back, and i probably have a little more room

ive got my duratec as i say now, just looking at options, i think the mx5 sump looks like the standard st150 one but i am not sure, i cant really find pics. There is a guy on the locost builders site that does weld together sumps for £125, i maybe able to use that and mod it to suit my needs.
the mx5 down pipes, how much power and they cope with? It maybe an easy option for my installation,, but will have to have a good look at it when i get the engine in the hole. I think at some point i may go for some cams, so it could be starting at 150 bhp maybe at some point 190 bhp.

The MX5 and Fiesta sumps are different, I know a couple of people who've had oil problems after using the FWD sumps in a RWD application. It'd be easy enough to make a pickup pipe and use some sort of custom rear bowl sump.
MX5 exhaust manifold has the cat built in so probably not worth using.

oh the weld together sumps are rwd aplication, they are flat though look like they sit 3" below the bottom of the engine.
the exhaust manifolds it ink they are very simular to the st150 ones but with a slight kick back. If you cut it off before the cat, or use the st one, you can go into 2 1/4" say back then. I was just wondering if they where suck a big restriction, and do they cope with the power ok?
thanks!

why not keep it bmw with the 140 bhp 1.9 4 cylinder? long story , i had a m44 that can the bigger crank, and shric cams, it did 180 bhp and 160 lbs, i was told by an engine builder the volvo would do 190 bhp and more lbs, so i went down that route. It didnt, so to get back to my m44 level i have to spend, so may as well spend on a motor that everyone wants, so i get some money back if i sell it.

The I4 engine is a good one plenty of power more than enough for a rear wheel drive car and you will still get a very good economy from it. I rebuilt the one for my ST with new timing gear, big end/mains, rings everything and it goes a treat better and stronger than a Zetec and no timing belt to go twang on it either. I have a manual for the ST that has the engine info in it if it's any help PM me? Pete

Yeah that's the right timing tool.
You'll need a new crankshaft pulley bolt and diamond coated shim. If you're sticking to a stock ish rev limit you won't need ARP bolts. I can get you a price on bits for rebuild if needed, always makes me laugh at the ridiculous prices the normal Ford specialists charge bits for these are pretty cheap.

thankyou! that would be good on the rebuild stuff!! I don't know what the rev limit will be set at, for now standard cams, later not sure, have to see how it performs. what should i limit it to now?
my mate is already taking the p1ss out of me, saying my water rail looks traveller lol. Recons itll blow up as i wont spend on it. Its not i wont spend, its where i don't have to, i wont.
thankyou!

I can't see how anybody would blow a stock ish one up. There's not much to them really as long as you get everything clean it'll be fine. I'll get a price together tomorrow. Is your crank alright?

thnakyou!!
i havnt taken the crank out yet, but there is no reason to think there is anything wrong, i mean, everything else looks really good.
I am thinking i may push it to 7.5k so maybe do the arp bolts anyway i don't think they are that expensive?
the only bad thing ive found so far, and it is a bad one, ive rounded maybe 10 bolts on it, some have rusted too. on say the m44, this just does not happen, ill be replacing quite a lot of them.
i have to say, i am looking forward to seeing how this turns out.

It's quite easy to round most of the exterior bolts off if you're not careful. A impact gun, good socket and a lot of pressure usually stops it happening but that's only learnt through experience (I clicked over number 100 built a couple of months back)

i bought this today CLICK HERE that is so cheap, and they do fit escorts so i guess will fit my bmw. With it being new too, no mess to clean up for i get some extra capacity welded to it, and some baffeling. Just need to sort out a pick up pipe for it now. this is looking liek a very good move, just need a rx8 6 speed now.

The only thing about suggesting ARP bolts in place is that it may oval the crank bores due to a differing torque and clamping method.
I know in the M3 circles, some have noticed that this has happened on a few of them, and ARP suggest checking the bores for roundness prior to fitting. That said, many M3, well S54 engine users have used them seemingly without issues.

Housing bore ovalling is a concern with ARP bolts in general. Can't do much about it with stock rods any more - there was a supplier of oversize back bearings so the rods can be resized but they don't seem to be available. Because they're cracked rods you can't just machine and hone them like usual.

Had anybody done a duratec to pinto bolt pattern adaptor plate yet? Are the 4 cylinder duratecs the same pattern as the V6?

Yeah you can get adapter plates. Pretty sure the I4's are a bellhousing pattern to their own.
