If you can do an s14 swap for the same cost as an m50? Which would you choose?

If the engine was rebuilt by a reputable S14-knowledgeable shop, and you can get it for the same price as an M50 swap, I say, go ahead.

My swap costs started to balloon out of control because I was missing small parts here and there that quickly amount to a lot of money.

With an S14 installed, an E30 is very balanced at the limit, so if you do a lot of tight and winding HPDEs or autocrosses (noncompetitively), it'd be awesome. Otherwise, if you're looking for a DD engine that is nice and torquey, get an M50 (or S50/2 if you can).

Honestly, I'd rather stroke and megasquirt an M20 than to drop in an M50.

Like both but for everyday use M/S5X S14 is not very fuel efficient around town due to lack of torque. I like my S14's but the smoothness of the sixes are perfect for daily use.

I have an S14 that is 277K miles on it and starts everytime, they are like any engine you do routine maintenance and they continue to work.

Talk with FredK, he built a US equivalent of a 320iS two years ago. They add up quickly and remember you need proper transmission.

Id take an m50 e30 over an s14 any day. unless its an m3
even my s14 2002 is underpowered. I guess its all relative but i need more powa

Aren't you running a 2.5l s14?

Now that's a qualified opinion from someone who has owned both.

But the M50 isn't more powerful than the S14 Blunt. ??? The only maintenance the S14 requires over the M50 would be valve adjustments, cap/rotor vs coil packs. Tensioner if it is a problem can be upgraded to S50. Keep it good tune, not too aggressive chip, the oil level up, watch ur pressure and it'll last you 200K+ miles.

DASC what you already have.

Is the S14 a 2.3 or a 2.5?

[Farbin Kaiber]

There are a bunch of maintenance items, but they are the same ones that would be suggested for the m50, but they are expected to be more pricey for the Motorsport powerplant.

Seals, gaskets, hoses, plugs, waterpump/t-stat, etc. IIRC, the tensioner is an important one on the s14.

The engine has 60k on it since the last rebuild.

Are s14's reliable when driven daily? If I swap it the only mods I would do will be chip,intake,cams,exhaust.
