I took off the valve covers and rocker arms with nothing glaringly wrong. So the motor and transmission will be coming out.

I was out driving and pushed the rpms too far I believe.

Strange noise (does not sound like a bad bearing) and it seemed to be running on only half the engine.

Mueller love how you can handle all of the electrical the way that you do. You're a wizard! Love the sound on that 6. It really does sound like a flat 6. How did it pull? Great job!

Just a thought... (IMG:style_emoticons/default/idea.gif)

From Wikipedia:

"One unique feature of some J-family engine models is Honda's Variable Cylinder Management (VCM) system. Initially, the system turns off one bank of cylinders under light loads, turning the V6 into a straight-3. Some versions were able to turn off one bank of cylinders or one cylinder on opposing banks, allowing for three-cylinder use under light loads and four-cylinder use under medium loads. "

Maybe VCM system is stuck on.

Chris, the later motors have that feature.

Motor is out, is that style of clutch plate a friendly type for street use?
Seems to be on or off for me.

That metallic puck clutch is unforgiving. You should put an organic stock disc in there. I'm running a stock LUK clutch setup on my 1.8t and love it.

Dump the 6 puck springless racing disc.

I don't know if a stock 914 disc will hold but you want that style. Kennedy might be the better place to go. They will ask if it's 9 inch (bus 228mm iirc) vs 215mm so measure first.

Mine is a Sport Kevlar from Clutchmasters good for 320hp or so but I planned ahead for a turbo... 20 years ago (IMG:style_emoticons/default/rolleyes.gif)

Yea, I keep looking at the Subaru 5 speed transmission sitting next to my car thinking how easy it would be to just grab a Subaru 6 cylinder and go with that.

Agree with everyone on the clutch, and can sure see why a Subaru flat six is appealing from a design and philosophical standpoint.

What's the power delta against the V6, Mike?

While I commend you for tackling the road less taken, I have to agree with the Subaru route. We’re all pulling for
you to get your car on the road.

From a quick search it looks like about 30hp to 50hp advantage for the Honda motor.

Another option is to part the car out, recoup a few grand and sink that money into our 242 (IMG:style_emoticons/default/smoke.gif) (IMG:style_emoticons/default/screwy.gif)

Eh you’ll get a lot less for it parting it out Mike. Any idea what’s wrong with the engine? Is it toast for sure?

I'd be very inclined to just figure out what went wrong first, and then go from there.

No, I think it is something minor, I think the frustration of working on our 20 year old stove top and oven right now is making me grumpy.

I'm taking this as a sign to fix up the engine compartment and do some welding, there are some holes in the firewall that really need to be addressed properly.

I know the frustration. I have parts everywhere.
But hang in there, things will come around.
The good news for my build is that I get to put lower compression pistons in it to handle the boost better. There's always a bright side. Well, most always. (IMG:style_emoticons/default/blink.gif)

I was going through my tool box tonight and found my compression tester and leak down tester.....after I removed 1 cylinder head already..doh!


This head looks good, no signs of valves kissing the pistons.

The other head is going to be a challenge, 2 of the head bolts are damaged so I'll have to drill the heads off.

All 3 marks for TDC for the cams and crank line up perfectly so I highly doubt the belt jumped.

Sorry to hear you're having problems and it seemed to be running well, except for running too hot. But, you will for sure get it sorted out.

I like Centerforce Dual Friction clutches (use with a matching Centerforce pressure plate and balance with everything). On 914s and other mid-engined cars too. Not as harsh as the 6 puck ones, but can handle lots of torque.
