anyone swap in a honda engine? Options

[mark21742]

Just curious if anyone has dropped a newer (mid 90s) Honda Civic engine in a 914?

I have a 96 1.6l engine, harness, fuel injection, all hardware and also have a turbo charger laying in the corner of the garage..... The combo should put down a very reliable 250 hp and just had the gears turning in my head about the thought of it.

Someone has put an S2000 engine in one. Most of the Honda engines run counter clock-wise. So you would need to flip the diff. The newer K-series engines run in the correct direction.

I think there is a member named FASTHNDA or similar that has done it.

I've never opened up one of these trannies, is it as easy as taking it apart and just flipping the diff over, or would it need machine work to flip?

[Cap'n Krusty]

Requires the fixtures, which are fairly rare and NLA.

Great link Rand! Thank you!

Ok this may or may not be a dumb question. Can you just flip the whole transmission upside-down and just plug the vent tube that is in it now and re-drill a new vent in the case, and would it still get proper oiling if flipped like this?

Which type of honda engine do you want to use? The D-/B- and H- series spin the "wrong" way , The S2000 F20 engine and all the K-series spin the "right" way and do not require you to flip the diff.

For your info: The H22 is much heavier than the B16 and prone to oil starvation damage, So is the B18, The best and strongest engine is the B16, that is for the old generation. You can boost it, charge it and as long as take very good care of the fuel injection part, that is, the right mixture/ecu program, you can beat the hell out of it...
Stay away from the D-series, unless you mod the hell out of them for big bucks, they will yield too little of HP profit.

For what it's worth: forget the old generation and because you're in the USA, the K-series are cheap. no flipping the diff hassle and it is truely an amazing engine!!
Charge it, get a K-Pro ecu and you'll never go back to the aircooled stuff ( no offence guys (IMG:style_emoticons/default/smile.gif) ).

Do not expect V8 torque, but high rpm fun with hp figures perfect for the 914.

Also a good option is the Honda S2000 F20 engine. Almost identical to the K20 with a few minor differences, swap a K20 valvecover and camgears and this engine can also use the K-pro ecu.... stock 240HP 9k rpm....

I've been building Honda engines for over 20 years now and I still think it's one of the best ever........

I was looking at the B16, because it is already sitting in the garage and I have all the parts to make it work and run all the way from the computer to the header

Then you need to flip the diff, or buy a G50 911 transmission and use it upside down.

KEP ( kennedy engineered products) sell the adapter plate and flywheel to mount the B16 to any porsche/ Vw transmission.

[Dave_Darling]

The 911 transmissions spin the "wrong" way already for a 914. The problem is that they are designed to have the input spin one direction--flipping the diff only changes the direction of the output. The internal bits are designed to spin one direction, and they generally will be less happy when spun the other way.

Corvair engines spin the "wrong" way as well, and the general solution for putting them into VWs or 914s or what have you is to rebuild the engine with a "reverse rotation cam" so that the engine spins the other way.

You can use a 911 transmission (901, 915, 930, G50, etc.) without flipping the R&P with the B-series Honda engine. (One Rennlist member ran an unmodified Corvair motor and a 912 transmission, at least for a while.) But the durability of the transmission will be a real question.

Flipping the diff is easy and requires no special fixtures or tools. Some steps, but nothing exotic.

If you run the tranz in revers then the guts will all be in reverse, even if the output is going the right way.

[mark21742]

So I take it you would also need a starter that turns and engages the opposite way too?

Your flywheel will rotate in a different direction than intended, only by reversing the diff, your output will be the correct way. Since the flywheel will rotate in the direction the new engine does, you will also need to adapt that.

The bseries has the startermotor on the same side as the 914, maybe KEP has a solution to mount it on the other side of the adapterplate. Give him a call, I visited him when I was in LA a while ago and discussed the way I wanted to have mine made, he is extremely helpful and can cnc just about anything

He made my adapter for a V6 NSX engine to an inverted G50 for my mid engined Honda Integra

I'll have to look at it some to see if I can just use the Honda flywheel, pressure plate and modify the Honda starter, then use the Porsche clutch disc. It's been a long time since I looked at the Honda engine, so it might be close, or way off....guess I have to do some measuring

[Hontec]

The KEP setup uses a new flywheel that uses the Porsche clutch, maybe he has a solution that enables use of the honda starter, but most likely it has the porsche ring gear and requires the porsche starter.

[mark21742]

Don't get me wrong, I have nothing against KEP, but if it is something that I can take an afternoon or even a weekend to fabricate and save a couple of hundred dollars by doing my self I'd rather do it. Plus on the end i can take more pride in it because I made that part instead of buying it.....am I nutty for thinking like that? Maybe lol

[mark21742]

Do you happen to have a link to build on you Acura? Sounds like a great project!

[mark21742]

See, this is my problem, my stock engine is in good shape, but I can't leave things alone lol and I have this Honda engine, and I also have a rebuilt GM 4.3 sitting here too, but the 4.3 has a carb on it and I wouldn't want to turbo it unless I swapped it over to fuel injection, plus it weighs a lot more than the Honda engine does
