datzenmike Posted November 16, 2013 Report Share Posted November 16, 2013 Z22 87mm to 89mm was about $200. Hot tanking and hone included Decking the block 1mm about $100 Milling the head 1mm about $85 Quote Link to comment
EricJB Posted November 16, 2013 Report Share Posted November 16, 2013 I think I was quoted $360.00 to bore 85 to 89. Not including hot tank. Quote Link to comment
hang_510 Posted November 16, 2013 Report Share Posted November 16, 2013 The problem with curious why you went with steel over brass freeze plugs? Quote Link to comment
EricJB Posted November 16, 2013 Report Share Posted November 16, 2013 The only job they had was to hold the concrete in. Quote Link to comment
Z-train Posted November 17, 2013 Report Share Posted November 17, 2013 510-I can't speak for him,but when I was replacing the freeze plugs on my Perkins,no-one had the right size in brass. Quote Link to comment
jvb5577 Posted November 17, 2013 Author Report Share Posted November 17, 2013 I got lucky with my brass freeze plugs, Napa here in town had them in stock. The look of the brass plugs looks way better in my opinion. EricJB, curious as to why you had to concrete you block? Was it just for boring or does it help for the drag racing engine?

datzenmike Posted November 17, 2013 Report Share Posted November 17, 2013 All out dragsters used to do this back in the day. The run only lasts seconds and there is a huge thermal heat sink. Quote Link to comment
EricJB Posted November 17, 2013 Report Share Posted November 17, 2013 Thin cylinder walls get distorted from heat over time. Filling the block eliminates that problem, making the block rigid. Not for street use. Quote Link to comment
hang_510 Posted November 17, 2013 Report Share Posted November 17, 2013 B) Napa here in town had them in stock. same here. Quote Link to comment
antonis Posted November 18, 2013 Report Share Posted November 18, 2013 ok, yes the con rod from the L16 are 3mm longer and the ka24 89mm piston is about 3mm shorter , but which are the open chamber and close chamber head? my engine is the L18 and i have a spare L16 block withe cons and pistons. my target is run a cross flow head if i find one from the 910 bluebird, or if i dont to run my own L18. i was considering to match a 16 valve head, but here there are not any ka24 engines and bring one from abroad will COST A LOT... and i want the compression to be more than 9.5 to 11.and my rev range close to 9k.... i want it to be a high rev engine...

EricJB Posted November 18, 2013 Report Share Posted November 18, 2013 This is a closed chambered head, Also known as a peanut, or kidney. If your L18 has an A87 head on it, it might be closed chambered. But you will have to pull it off to find out. Quote Link to comment

L18 block bored to................... 89mm L18 crank............................... 78 mm stroke / 2 = 39mm L16 rods................................ 133mm KA24E piston......................... 34 mm pin height c/l crank to piston top............ 206 mm * c/l crank to deck height......... 207.85 mm *This is better with only 1.85mm or 11cc added to the combustion chamber volume.(everything above the piston becomes combustion chamber) Compression with an 89mm bore, KA-E piston, L18 78mm stroke is as follows... Open chamber head.............. 8.2 Closed chamber head............ 8.73 .... not too bad REVISION ONE The L18 block is beefy enough to deck 1mm so if we remove 1mm this is the equivalent of 6.2cc of combustion chamber removed and the compression now becomes... Open chamber head.............. 8.99 Closed chamber head............ 9.58 .... not bad at all. Now this is assuming that the L series heads heads are not shaved or milled. A KA24E head is out of the equation as it's over 20cc larger than the open chamber L heads. The KA24DE is almost exactly the same combustion chamber as the L series open chamber head. Good choice!

antonis Posted November 19, 2013 Report Share Posted November 19, 2013 its like this forum is an open book, you always find an answer !!! Thank you guys! Well, i will go the old way using my own L18 head , i also want to keep the looks of the original engine with only changes like the throttle bodies ,nothing to show that is a fast motor in the hood... any suggestions on the cam and springs? i ve heard that iskenderian cams are good...

datzenmike Posted November 19, 2013 Report Share Posted November 19, 2013 Forgot to mention that the bore increase is substantial. The L18 is now a 1,940cc motor. I guess you could call it a big bore L18. Quote Link to comment
EricJB Posted November 19, 2013 Report Share Posted November 19, 2013 With an 89mm bore you will have to get creative with the head gasket. Most use a Z24 head gasket, drill holes where needed, and graft an L timing cover piece to the front. Copper ones can be custom made too. Quote Link to comment
jvb5577 Posted November 27, 2013 Author Report Share Posted November 27, 2013 Just did my 500 mile oil change... well it was more like 630 mile oil change. Didn't burn any oil. The oil had a shimmer to it. Seems like there was a little metal particles in it. Everything has been doing great. Compression is at 179-184 across all cylinders. Just wanted to check to make sure that this is normal. Quote Link to comment
jrock4224 Posted November 27, 2013 Report Share Posted November 27, 2013 true story .. im a expert at the wrong one and I love my exedy clutch .... cheap and firm and grippy...like my hookers Quote Link to comment
jvb5577 Posted November 27, 2013 Author Report Share Posted November 27, 2013 I am running an exedy clutch. No complaints so far although I am not starting to really abuse it so we will have to see what goes first, clutch, transmission, or diff Quote Link to comment

jvb5577 Posted November 27, 2013 Author Report Share Posted November 27, 2013 Thank K_trip just what I was hoping for On the fun run I opened her up a little and WOW. Its got some power compared to my L16. Still need to get a good tune on the carbs... just been lazy on that. Only been pushing the engine to around 5500 but I am running the 38mm carbs and need to get my exhaust done. After that I will push it higher and see what she has. Feels good being able to chip the tires shifting to second and third. Also can't complain about being able to do 100mph on the freeway no problem :devil: 1 Quote Link to comment
Sealik Posted November 29, 2013 Report Share Posted November 29, 2013 The oil had a shimmer to it. Seems like there was a little metal particles in it. Hmmmmmm......That can't be a good thing. Quote Link to comment
jvb5577 Posted March 23, 2014 Author Report Share Posted March 23, 2014 Hmmmmmm......That can't be a good thing. I haven't done another oil change yet, but motor has still been running STRONG. I will confirm when I get my next change done, which is soon. Quote Link to comment
Doctoraudio Posted December 20, 2020 Report Share Posted December 20, 2020 Ding! Dong! Do you still have the engine? Quote Link to comment
