s14 head on an m10 block?

[jgentile]

its not worth the time and money youll spend on it

[jgentile]

it works, there's a guy on this board with an M10, the S14 head and weber side draft carbs. :)

S14 parts are insanely expensive though.. unless you really want to keep a 4 cyl for weight purposes, you'd be better off doing something else (turbo, M50 swap, etc).

m50s are striahgt 6s :?

I don't understand where the cost would be, other than the machining to line the ports up. I have access to that for cheap. I wanted to know if there were any special parts that would need to be fabricated to do such a thing. Cost isn't the issue, I like doing things like this. I like to be a little different from the crowd. I live in KY and I wear shoes. get my point? :D

If cost isnt an issue and if the head isnt to wide, then just match water jackets and your on your way. Also you will have to change the chain length. Oh and if the s14 is a double chain than use a 320i M10 crank as they were double chains, but they are a little heavier.

[mcgrath]

will the s14 chain work? I know the s14 crank and rods can be fitted to an m10 block but I don't know where to get those. I just know where some heads are.

[boostboss]

Not sure about the chain, with the crank and twin cam. But a chain can easily be broken and rejoined at a proper machine shop or engineering place also a motor bike shop may be able to help. I would not do it yourself if you havent done simillar before as a snap chain leads to fcuked pistons and bent valves. $$$$.

Your best bet is too find someone with an s14 or at least the head and drill them or get a workshop manual and read the specs.
I thought the s14 pistons dont fit in an M10 as they have to thin a bore?

[boostboss]

I think if this upgrade does happen you will need to change the computer as the l-jet is very average with mods, look into the smt6 or simillar, you boys seem to love em over there.

[mcgrath]

it probably wouldn't be injected unless I converted it all to the m3 speficications (injection,intake,etc)

[E30godz]

a carbed faux S14 sounds interesting

[boostboss]

No carby. dont ever use a carby on a injected motor! esp half a m3 engine.
Why take a step back????

M3 engine was based off of the M10. If I could find a block to go with the head I would just build an s14. Nothing wrong with carbs. Im runing a Mikuni 44 PHH with lynx sidedraft manifold and I had no problems keeping up with my 84 325e which has almost half the miles of my 318 on it (170k on the eta)

[boostboss]

yeah but whats your fuel economy like and how long does it take to start on a cold day....

[mcgrath]

Fuel economy has decreased some but at the cost of more power. Starting in cold weather is hardly different from injected with the starter valve openend (aka choke)

[boostboss]

Sorry, what car has been carbied???

If its an m10 is it using a 320i head/manifold ??

[mcgrath]

I'm using a Lynx single side draft manifold with a Mikuni 44 PHH sidedraft carb. It is an M10/b18. If the s14 head on m10 block project doesnt go through then I will build up another m10 I have and it will run dual mikuni 44's or weber 45's. Why build up an m10 you ask? Because everyone says don't :twisted:
