Atomic Posted January 25, 2020 Author Report Share Posted January 25, 2020 (edited) Spent some time and made the copper gasket layout, drew a pencil sketch over the block and scanned, then transferred to CAD: I will print it out first and test what should be modified, but i can start to ask for quotations for water jet cutting Edited January 25, 2020 by Atomic 2 Quote Link to comment
Atomic Posted January 25, 2020 Author Report Share Posted January 25, 2020 (edited) Bought new tomei intake gaskets from blackhawkjapan, should be here in 4 days https://www.blackhawkjapan.com/?rfsn=3717819.124d3d Also ordered AISI 304 stainless wire 0.041 inch thickness for the rings. Found it with 68 meters, so that should last quite some time, lol. Cost 40 bucks Edited January 25, 2020 by Atomic Quote Link to comment
datzenmike Posted January 25, 2020 Report Share Posted January 25, 2020 This is for a KA24E head which pushes water into the left side of the block past the cylinders, up into the head and right and out the intake runners and the very front of the head. L series flows from the pump into the right side of the cylinders up, and out the left side of the head, basically opposite. This is a Z22 block so even more complicated.... the coolant flows out the right side of head. Quote Link to comment

datzenmike Posted January 25, 2020 Report Share Posted January 25, 2020 Cost $2 and a couple of hours work.... and 3 hours of thinking. Quote Link to comment

Well that certanly was cheap, I might want to make a couple of extra ones to sell. So thinking about water jet cutting Quote Link to comment
datzenmike Posted January 25, 2020 Report Share Posted January 25, 2020 I have an $80 drill press and tin snips. Fleshed out the cylinder holes with a cylindrical sanding roll and electric drill. Quote Link to comment

datzenmike Posted January 27, 2020 Report Share Posted January 27, 2020 Can't you cut through 10 at the same time?????? Quote Link to comment

Atomic Posted January 28, 2020 Author Report Share Posted January 28, 2020 I weighted the pistons and rods today. Pistons are in weight specs within +-0.3 grams and conrods are within +-0.7g. So I think I should be fine without balancing things? Quote Link to comment
Atomic Posted January 28, 2020 Author Report Share Posted January 28, 2020 Bought New CBX 3 ceramic surface treatment liquids for cylinder head and pistons. Still not sure if i should coat the New fresh pistons. Quote Link to comment

Also check the pin weight and bolts.... You might be able to make all 4 setups the same weight atleast .... The guy that balanced my setup had everything from the clutch to the front pulley balance to within .1 of a gram.... Quote Link to comment

I mean, 1 ml drop of oil will add 1 gram to the system already 1 Quote Link to comment
Atomic Posted January 29, 2020 Author Report Share Posted January 29, 2020 Picked up the cylinder head from the machine shop today: He smoothed some sharp inner corners of the intake manifolds and assembled the head and put new sleeves in. Also lapped all valves and contact surfaces. I'm still looking for a motor shop that can do the o-rings to the block, 5 shops have already said that they don't have a machine to do so...

datzenmike Posted January 30, 2020 Report Share Posted January 30, 2020 Probably for the same amount you can buy the tool that does this and cut your own. https://www.amazon.ca/Isky-Racing-Cams-100-GRM-Groove/dp/B00C2J67FE Sell it when you're done. Quote Link to comment

Going to be a damn risk if i'm buying and selling as used, especially in that price range. And I'm not too much into hand drilling my own ring grooves with tight tolerances. I have seen some videos with ppl using the isky tool tho, results are varying. Quote Link to comment
Atomic Posted January 30, 2020 Author Report Share Posted January 30, 2020 (edited) Found a machine Shop that can do the rings. It will cost 100 euros To machine 4 of them. Ill be taking the Block To them on next monday Edited January 30, 2020 by Atomic 3 Quote Link to comment

Wouldn't it make sense to oring the head too? I poked around quick and found this... Seems like they might want a receiver groove in the head to match the block oring..... I am by no means knowledgeable in this subject.... its just a thought I had and a curiosity.... Quote Link to comment

I know, i think i posted this on previous page already: http://www.engineprofessional.com/articles/EPQ216_60-62.pdf The thing with the aluminum head is that if I groove it, there is a chance it might be too brittle and it will just chunk pieces out of my head under high load. So I'm good with just grooving the block atm. 1 Quote Link to comment
Atomic Posted February 1, 2020 Author Report Share Posted February 1, 2020 Made some dimensional drawings for the block o-rings: 1 Quote Link to comment
Atomic Posted February 3, 2020 Author Report Share Posted February 3, 2020 Got the block to the machine shop today. Lets see when it comes back. I'll try to prepare other parts meanwhile 3 Quote Link to comment
Atomic Posted February 4, 2020 Author Report Share Posted February 4, 2020 Finally made some M6 threads for the balancer pulley and got the trigger wheel mounted properly, instead of just being held down with crank bolt. Got the 8th tooth aligned with the TDC mark: 3 Quote Link to comment
Atomic Posted February 8, 2020 Author Report Share Posted February 8, 2020 I'm having big plans for the intake manifold upgrade and something regarding air charging. Let's see how the negotiations will go next week. Aside from that, I'm really in need of another donor oil pump from any A-series (Except A10), oil pump. I have cracked two gears when trying to pull them off from the shaft as I try to build the high volume pump with fusion of A- and L series pump. So if anyone has a cheap $ ass A-series oil pump laying around hit me up. The gear that goes to the camshaft has to be in shape, otherwise the condition can be whatever. Quote Link to comment
