914World.com _ 914World Garage _ Honda V-6 in the 914

Posted by: tomrev Dec 19 2015, 03:04 PM

Thought I'd put up a few photo's of my current 914 project. I had a six from 1984 to 1998; started with the 2.0 T, then a 2.0S, to a 2.7, and finally a 3.0, with RSR pistons, Solex cams and a few other tweaks. She was a blast to drive, and I drove her to work, and vintage raced her for many years. About six years ago the 914 urge returned, and I built a few V8 cars, one with a LS, the other with old school SBC. They were both cool, and super fast, but just didn't sound right, so I began thinking of another six. Once the price shock passed, I knew it wasn't going to be a Porsche six, and started learning about some alternatives, and settled on the Honda 3.5 V6 from the Pilot, etc. They are all aluminum, variable valve timing, compact, light, and dirt cheap, and make around 250HP, and Ft. Lbs, a nice level for a 914. And happily, Kennedy makes the adapter kit, so that part is out there.
After a trip to the junk yard to look at, and measure, it seemed close enough to bring one home, and really start playing with it. I am aware of one other 914 with this engine in it, but it's a solo car, with out a trunk floor, etc., so one problem fitting it in. I have a nice 20K original car, too nice to start cutting up, so if the engine wouldn't go in, I'd give it up. (The car was a V8 car almost from new, don't panic!).
The engine is very compact, but the intake spreads out over the gearbox, and would stick way into the trunk. Fortunately, the intake can be flipped 180 deg., and by cutting off the throttle body, and re-welding it onto the side, the engine becomes nice and workable. It is a tight squeeze, but fits almost like it was designed to be there.Attached Image Attached Image

The intake and water passage mods: Because the dune buggy guy's are using this engine, there are sources for de-bugging the ECU, and the main things you have to do to make the install work, are the pictured mods, and making a front engine mount.

Neat! And thanks for posting.

Are those your welds? They look great...

I'll be watching this for sure. Those engines are AWESOME. I have a 2007 Pilot with that engine in it. I couldn't be happier.

Posted by: Cracker Dec 19 2015, 03:13 PM

Looks good...how much does the complete engine weigh? We've had an odyssey in the family for the last 15 years and never once ounce of engine trouble. Good choice.

I"m looking forward to hearing it; the firing order is from front to back, side to side, 1-4-2-5-3-6, so it could sound pretty cool. Once the engine bar comes back from the powder coater, I can put is back in for good, and finish up exhaust pipes, and plumbing.

I think with the flywheel, clutch and alternator it will weigh 365 lbs. Weight is up higher in the car, as it's a 60 deg.V, but at $450. it's a nice start! On the welds, I'm good with a Mig, no so with Tig, so I make all the parts, superglue them together, and have a weld shop finish them.

I had an 04 RL. That motor is the best and will run forever. Easily oil changes too!

Posted by: Mueller Dec 19 2015, 08:19 PM

Nice start...I think if I ever do another swap (or should I say if I ever start another swap to give up on and sell) this motor would be the one to pick!

Andy, can you create a filter so I don't see anymore conversions like this so I stay focused? smile.gif

Amazing how large a 914 engine bay is, isn't it?
Who would have thunk an engine that tall would fit..and the price is right!

So cool! That's the swap for me, have a 2003 Pilot & quite happy with the engine, 175k & not even a plug change, just planned timing belt change. Big fan of them, can't wait for more updates.

Looking good. If I had to do it over get the 3.2 I think to turn it sideways in the 914 and use the 5 speed with limited slip and axles into the 914 hubs 24 hrs all day and night.Attached Image Attached Image driving-girl.gif

I thought about that also since I worked in a major Honda dealership in the shop. I took the measurements and after you line up the max angles for the CVs and get the trans where it's not dragging on the ground, you end up with the engine partially in the trunk and sticking out about 5 inches worth. I hated to give up on the idea because it's such a sweet package all in one - plus you could call it a Pornda... shades.gif

No kidding! note the chunk of plywood over pipe lengths. Trying to raise the package up, without having it tip over is a scary process, as it is pretty top heavy. I forgot to mention that I had to eliminate a 1-5/8's in. spacer between the lower intake runners and the upper air box section.The 3.0, and 3.2 motors don't have it. It lower's the torque curve for the heavy, automatic trans minivan, and won't matter in the light 914. I was so happy when I figured out it could go, as it would have made the engine too tall to fit. Then I figured the engine lid catch would be in the way, but it too clears by a tiny amount. Yes!

Nice eh? Had to start somewhere, so i could think out the front engine mounts, but it was a SLOW process raising her up without losing control of the whole thing. Up until the end, it did not look good, like the shifter would be un-useable, etc., but after the last few inch's, suddenly the shifter was unshrouded, the engine lid shut, and the only body mods will be a small bubble cut, made in the forward trunk floor, for the thermostat housing, and the targa top will be able to fit as original, which I couldn't do with the Chevy installed. I could even re-use the Chevy spacers made to locate the trans rearward, by flipping them forward 180 deg., and still have a nice open area between the engine and firewall. Marking and cutting the trunk pocket will be next.

Add two hair dryers and you can make some pretty stupid HP with these engines. What are you using for engine management? AEM?

Why bother with the 901 gearbox? There are so many better modern options that would also work with that engine. The Boxster trans, the Passat trans, etc. Much better shifting, gears, etc.

Boxter gearbox is pretty heavy, and bigger, isn't it? And my box was just gone thru by Dr. Evil, with longer Chevy gears, so I want to try it out, and see if I like it with the Honda. Seems like most other box options would mean cutting up the trunk floor, and I want to keep the car reasonably stock. Agree that these engines can make serious power, but then the box is an issue, and $$$ start flying away. I have a vintage Supervee to race, so am not building the car as my ultimate ride. The Honda would be a great option to go that route 'tho, as they will safely put out 400 HP, without any inner mods, and with better rods/bolts, and pistons/cams can make a shitload of grunt.
For engine management, I am using a late 90's stock ECU, that has had minor tweaks, and is pretty reasonable. ( $850. with the engine harness trimmed).

Single hair dryer 400hp but Carl at vetch performance says race gas only otherwise it's a time bomb without serious mods

Posted by: tomrev Dec 20 2015, 03:04 PM

Marked and cut out the pocket to clear the water passage; will weld up a box there to retain some structural strength. Also pic of the intake spacer that came out, to shrink the engine height. I'll also be able to rebuild the upper hole made to clear the Chevy dizzy.

Is your Prius a 3.5 Honda engine? I ran my RL for 8 years and 210K. The master tech at Acura told me that he's seen popped plugs on the 3.5 and is better to change every 100K. Just passing it along.

I had a 2006 Acura MDX with this motor. I sold it last January with 409,000 miles.
Great motor just do timing belt, plugs and water pump at 100,000 miles.

Shot of plumbing; the supply fuel line is -8, run thru the longs, and into 10 micron final filter. There's a 100 micron filter in the trunk, between the tank, and the pump. Coolant has twin lines on each side, run along outside of longs, behind the side valances. Return will be -6 back to tank.

I don't want Tomrev's thread to get off track. The V6 build looks great and I hope he continues to post his work which looks outstanding.

Regarding the trans. I'm using 901 with shortened 3rd and 4th ratios due to the high revs. 5th is stock for Cruising. With a V6 I would think the stock ratios would do just fine.

No, she idles perfect. I eliminated the EGR, and tapped and plugged all the EGR tubes/ports in all sections of the manifold. Without relocating the TB, (and flipping the intake 180 deg.), there was no way the engine would fit, without a lot of body/trunk mods, and the plan was to leave the car unmolested, as much as possible. It has been a super fun project, with lots of stuff to fab, and $$ stayed pretty low, at $2K total. I think the power level is well suited to the 901 box, as well.

Isn't that like saying I don't need a 1000 watt stereo system? Just because you have it doesn't mean you have to turn it up all the way - the volume knob also turns the other way. You'd have to talk with members who have the big power numbers to find out how they like the rush and how they handle it.

Nice setup.

I was thinking about the very same thing since just last night....my 20 yr old son brought his new (to him) S2000 home.
I was very impressed with the specs!
>230 hp for a 2.0L 4-cyl NA (VTECH YO!)
And they are small and supposedly very reliable.

It's also funny that the S2000 has a Honda F20 in it, and MY DD has a Toyota FA20 (no relation of course), which I have also looked to put in a 914...

In stock form, the TB flows into the outer air box on the intake, so by moving it to the side, it still enters a common box, and seems to be a non issue. I researched the dune buggy shops that are using the Honda, and found a couple who will clean up the stock harness. Settled on Don's Buss Box, a guy in Az. who builds gearbox;s for buggies, and will supply a modded late 90's ECU, and go thru your harness for $850. He in turn has another buggy shop do the harness work, based out of Wa. It was done cleanly, and allowed me to concentrate on the welding / fab end of things, which I like best, and then just change the chassis wiring to mate up with the Honda parts. It only needs 6 wires to run, and control's the fan and fuel pump, as in a stock setting.

Nice! I think for a street car it's hard to use even 250hp in these cars.

Isn't that like saying I don't need a 1000 watt stereo system? Just because you have it doesn't mean you have to turn it up all the way - the volume knob also turns the other way. You'd have to talk with members who have the big power numbers to find out how they like the rush and how they handle it. There's some big hp race 914s that find their way to the street occasionally and probably love it! You know what they say - Enough power is great but too much is perfect! shades.gif

Of course you don't need a quadraphonic Blaupunkt.... especially when you've got a 1000 watt Alpine with all the trimmings!! aktion035.gif

F20 from an S2000.

You read my mind!
Nice setup.

I was thinking about the very same thing since just last night....my 20 yr old son brought his new (to him) S2000 home.
I was very impressed with the specs!
>230 hp for a 2.0L 4-cyl NA (VTECH YO!)
And they are small and supposedly very reliable.

It's also funny that the S2000 has a Honda F20 in it, and MY DD has a Toyota FA20 (no relation of course), which I have also looked to put in a 914...

That's 240hp @ 8300 and 150tq @7500, with a 9000 redline. Sounds great for a 914. Problem is that everyone who owns one drives at redline, thus the engines wear out much faster than everything else, if they haven't broken a rocker or cam. Replacement costs are up there too, as it was low volume and desireable.

I'm doing nearly the same swap as you, and I had some questions: Did you farm out your wiring/ecu work or do it yourself? I'm also trying to figure out what the best way to work the fuel system is regarding the keeping the Porsche pump v using a Honda one etc., and I'd love some input from somebody who's done it!

Stock pump won't flow enough. Honda one is in the tank. The Walbro inline pump would be the $100 solution.

Call Carl at vtec performane in Arizona he thinned out my harness sent it back with computer and 8 wires I have Honda j35 out of 2000 odyssey in my 914. 503-391-6300 he can also do your computer

Thanks for posting photos of your 3.5 L conversion. Your inventiveness and engineering skills are really on display! For those of us that aren’t experienced water cooled conversion folks could you post photos of your cooling system and exhaust? Also, have you driven the car yet?

I almost wish that I hadn't came across this thread, it really makes you think...

Great job on the conversion. Love Honda engines. I put the S2000 motors in several cars and its my favorite engine. Currently following Micheals lead and installing F20c in my 914. I set myself a 6 week deadlne to get it done.

What brake upgrades do you have.

Sorry for my delay in response; as I had installed a 911 Carrara front suspension, it already had the big rotors, and calipers, but I swapped out the calipers for the alloy Boxster Brembo's up front, and used stock 914-4 rears, that were rebuilt, because I want to retain the parking brake. I have been driving it all Summer/Fall: it runs very well, is fast as expected, with a lot of torque, and because of the modern design, and ECU management it always runs crisp, easy starting, etc. First gear is fine for starting, but it has enough torque that second gear feels like 1st., you can pull easily away from a stop in 3rd if you want. Nailing it in 1st, it will hit the rev limiter faster than you can react to shift, so for speed runs I just launch in second. As a few guys have noticed, I am selling her; the addiction for projects is hard to shake, and garage space and $$ dictate this. With all the cool parts, and the original miles at under 21K, I hope to get around $17K. It has been a very fun project!Attached Image

Did you have a build thread or anything like that? I'm gearing up to put a 4AGE 20V into my 914 and any guides that exists out there for something similar (K20, or any other inline 4) are of great interest to me.
