E30 M3 S14 IN MY TI?

[cossieturbo]

Hey mates... I was thinking about my 318ti's future mods. I was looking over my options and was thinking about a Supercharger or how about an E30 M3 S14 engine? Anyone ever installed on of these S14s in a Ti? The balance is very important to me so maybe I should fly to Europe, find a low mileage M3 Evo... buy it... tear out the drivetrain and carry it back with me on the plane. Yah sure. That would be cheap. Any input?

This was brought up before and I can see no good reason to use a S14 motor. They are expensive and expensive to repair.

[SewickleyBMW]

I know it has been done...especially across the pond. Definately expensive and you don't save much weight over the newer I6 motors. It would be cool if it was just a occaisonal driver. The s14 doesn't make as a great daily since it loves to live so high in the rev range. Then again the M42/44 isn't great either.

[needle332rur]

I thought about it, a well built 2.5 s14 can make upwards of 300hp at the crank. It's the most true race motor built by BMW along with the s38 and of course most euro M motors.

The S14 is a little taller than a lot of newer engines - might want to be sure that giant intake manifold fits under the e36 hood. Would be great fun though, even with minor upgrades that engine is fantastic...if not particularly quiet or smooth.

I have an old european car mag that has a s14 TI

Performance BMW has a S14 powered 2002 touring in it.

I dealt with a 88 S14 for 10 months and about 20k miles when it had 112k to begin with...it was fun, but I don't know it I would do it again. I love the e30 Ms over all the M3s, but I would rather work with a M42/M44 over the S14.

What about just building up a S42 replica...something around 2.1 or so displacement and building a ITB system for it.

[weezer]

Here's my thought on this and I've done my litte research after posting the original thread; unless the car is planned for serious track use that will be great idea. The S14 has similar engine configuration as the M44 with larger displacement, high comp. pistons, taller lifting cams, race header and long intake manifold runner with dual throttle bodies. The original 2.3L engine can produce around 200hp stock, but very high maintenance. We are better off putting an 2.3/2.5/2.8L engine with proven reliability with regular maintenance. The S14 engine, such as for racing purposes with a support team, needs constant monitoring and TLC after every track use. The engine itself cost as much as one of our used cars not to mention the care costs.
If one is till looking for a screamer four, got to http://www.bavengine.com/engine.html and get the rebuilt engine w/ performance option, plus some tweaking and you will get similar performance as the S14 with reasonable pricing and reliable.
I myself is seriously looking into the Bavengine option or a swap from a 323is.

[weezer]

panzer, that's exactly what my thought is. The Bavengine performance option adds 20% with stock everything; I'm wondering what happens an ITB were is bolted on to it. Perhaps similar performance to a stock S14?

[Panzer_M]

you can build a 2.1 out of either the M44/42.

actually a bloke did it in South Africa on a 93 M42 using a M47 crank(320d) and decked S50 piston with M42 rods...iirc...almost a replica of a S42 race engine heh. but alot more user friendly than a S14 I'd wager, since the most difficult part of the build is decking the pistons. But all most of it is parts bins sourced.

he also plans on using a cut down S50 manifold(Euro Remember so it's ITB not the US POS we get)

His only regret is he wanted to use a M44 block to get the oil squirters, but if you use the stronger M42 internals I don't think that is a huge issue.

btw, for 200hp just go with a M62 Blower and some tuning. it's possible.

[weezer]

I'm old school, I guess. I don't like using forced induction on stock engines; I prefer maximizing intake and exhaust first (ITB and headers), maybe down the road hotter cams and perhaps, larger displacement.

[Panzer_M]

I am the same way, I would rather have a lower hp but more reactive M42 in the Club Sport. Plus I don't know if the M42 being ODB 1 will be as tuner friendly as a ODB II M44 with a DASC.

[weezer]

I think the M42 is much more tuner friendly than the M44 in stock form. Dinan has a chip available that adds 11hp and 9 lb/ft for $299. I wish my M44 is like that, it was an updated M42 and pretty much high strung, reprogrammed and not much more can be wringed out in the software and cat back systems dept. So perhaps ITB coupled with headers and cat back systems might give us something. I know that the performance engine Bavengine offers has ported and polished cylinder heads.

[Dredder]

Unless you guys have a unlimited parts supply this project is simply going to cost you too much money. You are btter off putting DASC or an engine swap(m50/52-s50/52). In addition, when you have a swap you are not limited to the amount of power you can squeeze out like of our m42/44 engine. You can do it (money makes power), but in the end you are going to be asking yourself, Damn I should have done a ///M swap.

[AutoM3otives]

Don't bother with the S14. Too much $$$. It'll kill you one way or another.

I have been informed by a very reliable source that by building the m42/m44 up to 2.1 to its most "streetable-extreme", you'll be able to achieve stock e30 m3 performance. No more breathing room to push after that if you go all-motor. But a DASC 2.1 is possible, just have to build a very low-level low compression 2.1.

I planned on going thru with this, but I already have a tempermental 4cyl to deal with as well as higher plans for an e34 M5.

Plus my Ti hasn't even hit the century mark, so its still good to go.

[cali-ti]

i'd be very interested to follow your build up of a 2.1 ti. we have one on here already H3_2.1-ti. maybe we could get a dyno chart out of him? :)

[andrei]

How can you grow yoour displacement to 2.1. I mean what are the necessary parts.

New Pistons, Crankshafts, rods, preferrably fuel injectors and Hotter cams.
probably cost less than a swap(?)
No 6cyl. differentials or gearbox or drive shafts or suspensions needed...:wink:

[andrei]

But where can I get these form here in Europe?

[cossieturbo]

Well it's a DASC for me! Already put in the UUC Clutch kit. Next is the LSD, then rear sub-frame mounts and then the exhaust. Only after that will the DASC go in.
