Would an F20C fit into an E30?

[sofargone561]

the f20 motor is direct bolt up 2 the k series? i came into the car scene throu honda. the s2k is one of my favorite cars... period! the k20 is such a badass motor the only thing that stopped me from a k20 hatch was FWD. also as stated f20 will handle boost fine. theres a couple guys around here (souths FLA) with 500whp+ boost s2k's with stock blocks and shit

Dude. You're looking at engines starting with an F, and your engine starting with an S doesn't run yet? :p

:nice::-(:finger:

I like to think out loud... my DD has a pretty mile-y engine in it, and I might want to do something in the summer? Probably not though.

I mean the motors themselves are apples to kumquats, but...a 165lb difference is hardly "around the same."

Actually, in typical r3v-style I didn't even click the link and took him at his word.

But yeah, 100 kg is a sizeable difference.

haha thats fucking stupid. Why would anyone really spend money on that. That's pretty funny though

This setup makes well over 1k whp, I'm from the Honda world originally and if you have never played with water you default to thinking fire is better when in actuality water puts fire out.

The k series bolts to the s2000 tranny and you have a rwd, it's that easy, just because it came in a fwd dosent mean it's not a good motor.

K24 with k20 head are cookie cutter 300whp+ NA motors.
For NA horsepower to engine displacement Honda has been at the top for a while with the intro of the f20c taking over reins from the mighty s14, not even apples to apples when you compare motors; the s14 is way more performance outfitted.

I've thought about and am still thinking about this swap into my own e30 due to the responsiveness of the motor, I turbocharge BMW'S for a living but I am an NA guy at heart so response is big for me. My Honda that sits in the garage next to my vert will peg the 10,100 limiter BEFORE the pedal touches the floor, typical of a tuned Honda.

Oh yeah, the F20c and predecessor F22 will both make 600+whp all day on a 100% factory motor with the correctly sized turbocharger, once again pretty cookie cutter for the S2000.

I haven't pulled the trigger on this swap yet because honestly;

F20/F22 w/ trans = ~4k
S54 w/ trans = ~ 4k ( and yes I have bought them At this price)

S54 is the better for the price, I just sacrifice a bit of low throttle response due to the individual throttles - easy fix

Well you would turbo it obviously.

And yes I did say KA24, thought you guys would know which one I meant.

Anyways KA24 can e placed very far back in the engine bay, which means better weight distribution.

The oil pan does not hang as low, which means driving the car slammed would be way easier. The engine can be placed lower to the ground too for this reason, which means lower center of mass.

Someone that would be considering an F20C swap would not care about huge HP numbers. That's not what it's all about. Not to mention 400hp isin't even useful in an e30.

I was going to say this. As far as I can see, 400hp is more for the fun of it.

With both four cylinders you can place them both further back and have less weight over front of the car.

KA24DE is a DOHC engine capable of alot of power.... and they are cheap as hell because pull them out of 240s all the time to SR swap

You wrote Ka24, never specifying whether SOHC or DOHC, I still don't see the appeal of putting an engine in that has less power and less torque than an m20 only to have to make it faster. Pointless swap.

[5Toes]

Get out of here with that shit, because putting an old SOHC truck motor in an e30 is a good idea.

m30s are looking better and better to me.

I heard f20c's don't like boost too much either.

[robgoesvroom]

It's too tall or something, right?

Please post pictures, there were some Japanese ppl that did this a few years ago but I can't find pics.

Edit: Damn VinniE30 was quicker



Don't these look better?

[VinniE30]

How easy does the fc20 make 400 hp again, 150 lbs is nothing when you compare hp numbers. You don't have to use the t56 tranny which is why the combo is so heavy, you use it because t56 is bulletproof.

Maybe because they wanted the quickest kseries in the world.

I bet if I posted that on my home ep3 forum, they would get wet panties. I just don't see the point. They are probably also the only ones in the class of "fastest rwd k-series." lulz. Are they the fastest in top speed or 1/4?

I don't know what link you're referring to, and I never said anything about an LS1. I didn't say an F20C was heavy; I said it wasn't as light as you might think.

I had seriously considered this swap in 2007 or 2008 and spent a lot of time researching it. This is from memory, so don't quote me on specific numbers. But a stripped (no accessories, flywheel, intake, etc.) F20C engine alone weighs around 210 lbs, compared to 180 lbs for an M10 or 250 lbs for an M20 in similar condition. So it sounds pretty good, right? You figure when all is said and done, the compete swap should come in at around the weight of an S14.

But it turns out all the other stuff weighs a lot more than you'd expect. The F20C complete with tranny, flywheel, intake, and accessories ends up being around the same (or maybe a tiny bit more) than an M20. In the neighborhood of 470 lbs. Again, don't quote me on the exact number, but it's in that ballpark.

Anyway, none of this really matters for the simple fact that it doesn't fit in an E30 engine bay! At least not without major surgery. Spend a few minutes (as we did) with a tape measure and an S2000 and E30 side-by-side and it'll be obvious why.
