assembling project car 2.3 liter, finally
Why are you keeping the balance shafts? They are always a liability issue. Properly balanced you should have no vibration issues. Just wanted to point this out before you put the motor back in the car. It'd be easy to change now. I'm used to higher mileage early DSM's and I've personally seen a balance shaft failure. Its ugly, the whole motor gone.
Cleanliness is godliness when dealing with motors.
Are those push lock fittings for the oil cooler?
What RA finish did JAM complete on the cylinder head?
Looks good.

I am only revving this motor to 7300 rpm, so the cams are such are being designed to add in the torque/power band.
I believe my workshop is representative of every aspect of what we do. I had someone tell me the other day they'd rather have surgery on my floor than in a hospital.
--------------------------
This should be a fun project. Ill take some more pics today.... if I have a chance... i have to have the car flatbedded to the shop, its in our other garage. Sitting on the 18x9.5 forgelines hee he.
Cheers

they are pushlock fittings, very high pressure rated hose. We have never had an issue with the pushlock and its nice to setup.
I have a rather large MOCAL core, that is being turned, so exit out the side of the bumper, instead of the rather high pressure area in front of the tire in the wheel well. It's an evo 8 getting an evo ix front bumper.
While im at it, i need to thank the following:
Jackson Auto Machine (block/head/fluiddamper)
Bridgestone Tires (265/35-18 RE01R)
Forgeline Wheels ZX3-R
Megan Racing (coilovers)
APR Performance (Front evo ix lip and rear undertray)
Kartboy (hangers/shiftknob)
Stoptech Brakes (new 6 piston calipers with floating rotors)
hopefully im not forgetting anyone...

2.3 - 2.4 Builds. Why Run or Not Run Shafts
We custom machine ALL of our Balance Shafts for our customers.

We run the balance shafts in ALL of our 2.3 and 2.4 builds due to increased Internal Harmonics created by the 2.4 stroke crankshaft. These Internal Harmonics can cause serious issues for the life of the engine. When running the balance shafts in place it will allow the engine to not only run smoother (internally speaking) but release more HP and last far longer then without them. Balancing the rotating assembly is only part of the entire issue revolving "Harmonics". We have had EVO owners call us with their horror stories of their failed stroker builds, where sides of the engine blocks were breaking and blowing out, flywheels and crankshaft pulleys would be falling off after very little running time. All of this is caused by the violent- Internal Harmonics of the flat4 engine. We custom machine all of balance shafts for each and every custom 2.3 and 2.4 we build. Not a single failure to date, only strong running, long lasting engines.
Thank you CB!
Thank you CB!
if you want straightforward answers, you get them from JAM. They are very local to us, and it's great to have someone i trust.
I agree with them totally, with piston speeds, harmonics etc.... its the little details that create long term performance motors... we arent a drag racing company, so these strokers need to last me and my clients through road course events, and daily driving.
cheers, JAM ++++++++++++++++
