Muckman’s High Compression Super Build

[MrGurley]

lol this shit is Chinese to me other than I know its crazy valuable info for people who have the skills I lack!!! but I stay checking back to keep stacking knowledge bank!!!

I've never degreed cams using soft springs like that, it doesn't make much sense to me right now, seems inaccurate in a way

 

[Muckman]

The purpose is to align the cam centerline with the proper crank angle. The resistance of a heavy valve spring makes fine cam adjustment difficult. The soft spring only needs to hold the valve up. I don't believe it has any affect on accuracy of the procedure.

Yeah I don't see how it would affect the accuracy either. The gear is still moving X amount of degrees from the fixed center line on the part of the gear that is fixed to the cam itself. As long as the gear is keyed correctly and has accurate timing marks it shouldn't matter. Hell, you could do it while the cam is out of the motor if you really wanted to, because the cam has holes in it for you to line it at TDC and keep it there for timing belt install(I use allen keys to hold it there. Little trick I learned from donut). However, Muckman seems to have done it the more accurate way and not simply trust the markings on his cam gears. Unless I am wrong about that.

And don't pay much attention to lack of responses Muckman. It is because most of this is on a whole other level to most Honda people. Hell it even has more precision than I am used to seeing/doing. Probably why my motor wont stop its smoking issue, even after putting in a completely different long block essentially. Just keep posting and showing people the correct way to go about building motors. We need more of that around here. God knows theres enough threads that show the wrong way to do it.

I got the engine and assembled and Im working on getting it in the car. Here's a few pictures of the finnished engine.

Fidanza flywheel, 76ftlbs

My flywheel holder. I flip it around to torque the crank pulley bolt to 130ftlbs.

Im reusing my Clutchmasters Stage4 4-puck FX400 clutch. The clutch disc is looking thin. Hopefully it'll last 1 more season.

I have to agree with Nick, this is was over most people's head. I have no idea what's going on 90% of the time but it's still cool as hell to see

That is all

I put 100 miles on the new engine with the old tune (Neptune). 3 oil flushes later, no debris on magnetic oil plug so everything looks good. Im still getting that god damn cam surge around 3k at low load. So I guess it wasn't caused by poor valve seal last year. Must be a characteristic of the cams.

I decided to switch to Hondata so I could take advantage of their Coil on Plug kit and get off this evil MSD ignition.
I manually copied over all of the fuel and ignition tables.
I doubt the fuel values will be the same but I can adjust that with the overall trim as long as the curves are consistent.
I needed proof of life on the Hondata EMS before switching the ignition over.
The engine fired up on the first try but fuel was way off.
Thats all I needed to see so now Im proceeding with the COP install using Honda K20 coils.

Clean install of the Hondata S300 v2 board. No cutting of the ECU case for the USB header.

This thread is so detailed and if I read it all at once my head would explode. Muckman your is the S**T!!!

 

[randomhobo]

Can't wait to see how the K20 COP kit goes, have been curious about them for some time now but sadly I won't invest in it while having an autotragic.

Hondata CPR is installed. Later I want to redo the CPR harness loom, it looks terrible. I had issues with a dead tach because the stock OBD2b ECU drives the tach (not the distributor as it does on OBD1/OBD2a). I took the green tach output wire from the CPR box and routed it into A19 in the OBD2b harness to resolve this.

I routed the KnockSense 5v output into the Hondata analog inputs so I can log it.
Im happy I can use the knock sensor now that I don't have contact between the piston skirt and oil squirter making the sensor go nuts like last year.

I need to fabricate a bracket to mount the CPR and KnockSense boxes to but this is the first time in 5 years my ECU hasn't been on the floor lol

I've been street tuning and it runs fine. Everything is ready to get tuned.

Looking good man! I've been pretty much going through the same motions as you have been.

 

[JustinMcGee1]

You should be featured in honda tuning

 

[DaddyBuiltRacing]

They don't feature guys that actually build cool s***, instead they will tell you that your car isn't the caliber of build they look for....ask me how I know Now if you throw some stanced out BBS wheels on it, leave some body line gaps, then you might have a chance.

This car is sweet even without a Honda-Tuning feature

 

[randomhobo]

I wish I had your bank roll to build awesome things like this

Looking good man, keep up the great work/write ups!
