I'm BLUE Posted September 4, 2011 Report Share Posted September 4, 2011 Or I could make you a smokin deal on my l20.......... ^^^ That's an awesome idea ! Can't beat a good runnin motor if opportunity arises :) If you do decide to source some L24 rods , EBAY probably wants tooooo much (stroker rods are L24 rods for us Z guys too ) , check ZDriver , Hybrid-Z , etc (for non 9mm rod ones for least expensive) , etc ,,, I will ask a buddy if he wants to let a set go when I talk to him :) Quote Link to comment

Kramer Posted September 4, 2011 Report Share Posted September 4, 2011 So I was cleaning out the garage today... I knew they were there, just haven't given them much thought. Someone had an L18 in a box that I bought awhile ago. Disassembled. I also have a spare L16 short block. The L18, as a whole, are pretty beat. But, the rods, pistons, and crank appear to be in great shape. I've read a few things about people doing this-but no results. So who knows what? Being a starving student, this appeals me for the time being. Who can do the compression specs also? Quite a few combos to be made. Keep in mind, I have just the stock 210 head, and an A87 peanut head. L16 block, L18 crank, rods, pistons? L16 block, crank, rods, L18 pistons? I can even source some L20B pistons easily if compression of these combos are too high? Opinions? Thoughts? Numbers? Am I missing a combo, or something else? what are the l16 & l18 strokes?

I'm BLUE Posted September 4, 2011 Report Share Posted September 4, 2011 L24 rods and L16 rods are same length. oh yeah ! der der der ,,, knew something was missing on that !!! :lol: maybe its the piston pin location ,,, I know the 9mm's are more desirable for strokers ,,, 8mm's are used as well ,,, never done it myself ,,, maybe it was the piston pin location ? hhhmmmmm ,, spoke before I replied :unsure: :) Quote Link to comment

I'm BLUE Posted September 4, 2011 Report Share Posted September 4, 2011 Same piston height too. Just saw that !!! damn it !!! :) ,,, maybe it's the rod bolt diameters ( I speak again ) Good luck man ,,,I'm outta here can't help ya !,,,, sounds like a fun build :cool: Quote Link to comment

datzenmike Posted September 4, 2011 Report Share Posted September 4, 2011 L16 block and pistons L18 crank and pistons....1687cc stock with closed chamber head................................................... 8.4 above with flattop pistons................................................................ 9.36 Stock with 210 head.......................................................................... 8.6 Above with flattop pistons................................................................. 9.82 Quote Link to comment
flatcat19 Posted September 4, 2011 Author Report Share Posted September 4, 2011 Above with flattop pistons................................................................. 9.82 Just to confirm... L16 block L18 rods, crank, pistons A87 peanut head. Do I got that right? 9.82? 1687cc Thats sounds good enough to be fun. Not fast. But fun enough. Quote Link to comment
Kramer Posted September 4, 2011 Report Share Posted September 4, 2011 Here is one I am working on. CR is low. So I just need to bring that up a bit. So all L-series rods are the same lenght? Quote Link to comment
flatcat19 Posted September 4, 2011 Author Report Share Posted September 4, 2011 So all L-series rods are the same lenght? NO. Did you read that thread I pasted for you above? That will give you all L, alot of Z, some KA and some VG info. Very awesome source of information. When I first got into Datsuns, I read that twice a day for a month. Quote Link to comment
DRIVEN Posted September 4, 2011 Report Share Posted September 4, 2011 Just to confirm... L16 block L18 rods, crank, pistons A87 peanut head. Do I got that right? 9.82? 1687cc Thats sounds good enough to be fun. Not fast. But fun enough. Not exactly. Like Laecaon said earlier, L16 will have to be bored to accommodate the L18 pistons. The result will be an L18 with "L16" stamped on the ID pad on the side. Forget about what the block originally was. Bore X stroke = displacement. You're over thinking it. Quote Link to comment

Do I got that right? 9.82? 1687cc Thats sounds good enough to be fun. Not fast. But fun enough. ....no. The 9.82 compression was 210 head with flattops on an L16 block, L16 pistons, L18 rods and crank.. L16 block and pistons. (no need to overbore) L18 crank and rods. (increased stroke) Makes a 1687cc (stroker) motor with the compressions I listed previously. Boring the L16 block out to fit L18 pistons and using L18 crank and pistons make the L16 into an L18. .

flatcat19 Posted September 4, 2011 Author Report Share Posted September 4, 2011 Thnx Mike. Just one more question... What combination will make the best bang for the buck using my A87 head? If these seem unreasonable, I might just have to deal what I can to Swollen Member to snag his L20B. Quote Link to comment
datzenmike Posted September 4, 2011 Report Share Posted September 4, 2011 Just one more question... What combination will make the best bang for the buck using my A87 head? That would depend on what you have available for parts. Quote Link to comment
flatcat19 Posted September 4, 2011 Author Report Share Posted September 4, 2011 That would depend on what you have available for parts. Full L16 and full L18, minus block. Big chip on cylinder ridge. 240z or L20B pistons can be had easily. Quote Link to comment
datzenmike Posted September 4, 2011 Report Share Posted September 4, 2011 Parts on hand... Complete L16 (L24 pistons are only good in a stock L16 bore) L18 crank/rods/pistons (need to bore L16 block to 85mm) L20B (11.36dish) pistons. (only fit a bored L16 block) Go for size. Bore the L16 to 85mm and use L18 pistons,rods, crank and A87 head for a compression of 9.00. Using L20B pistons with the larger dish will drop the compression to 8.1 Or add up the cost to over bore, rings, bearings, gaskets and time and compare to getting the L20B with more torque and hp.

Yeah. I think L20B with my peanut will be the way to go. Bill...Let's talk aboot that L20 you got! :D Thanx Mike. Quote Link to comment
Dirttrack510 Posted February 10, 2012 Report Share Posted February 10, 2012 I'm reading this thread and I'm wondering if anyone knows for sure that the L16 block can be bored out to the 85mm size. That seems like a lot of boring from 83mm without having to sleeve the block. Also, here's the engine calculator I use for figuring compression ratios and engine sizes. it works really good and is super easy to use. :D http://www.race-cars.net/calculators/compression_calculator.html Quote Link to comment
flatcat19 Posted February 10, 2012 Author Report Share Posted February 10, 2012 Yeah. It's called an L18. I thought you just read the thread? Joe King. :P Quote Link to comment
