Silent Posted October 18, 2005 Share Posted October 18, 2005 3.1 stroker n42 block n47 head {z head, not max} STOCK crane 450 cam thing n36 intake runners, STOCK su carbs, sm needles msa header 2.5 header back exhaust to a fart cannon. msd ign, mallory coil, stock late 260/280 dizzy unsure of compression, this got me 192 rwhp on a 100/91 octane mix, and 38 degrees of total advance. oh, stock nissan air horns. over the winter, im doing a tear down to see what c/r i have, unsure of piston type in the motor, severe head work, and more c/r im going for at least a 75 rwhp gain. then bottle ontop of that Quote Link to comment Share on other sites More sharing options...
briann510 Posted October 19, 2005 Share Posted October 19, 2005 Did you make several dyno runs when you got your 192 rwhp? you said you are at 38 degrees total which is ALOT for a stroker. We run 30 degrees total on ours for best rwhp. Quote Link to comment Share on other sites More sharing options...
Silent Posted October 19, 2005 Share Posted October 19, 2005 the only reason i got away with that timing was the fuel mix. i made changes here and there and came up with 192 rwhp after the 7th pull. then backed it down to 35-36 degree's which came out to be about 182 and added some fuel to it for pump gas safety. balls out 192 rwhp. pansie mode, anywhere between 170-180. not quite the level you're at, but ya know. i found more fuel control tweeks here and there, and a few su tricks here and there that helped a ton Quote Link to comment Share on other sites More sharing options...
briann510 Posted October 19, 2005 Share Posted October 19, 2005 Agree its all in the tweaking...we gained an additional 22 or so rwhp re-jetting the carbs and such. Quote Link to comment Share on other sites More sharing options...
2003z Posted October 20, 2005 Share Posted October 20, 2005 Just spotted this thread - also I noticed the question "does anyone sell the stroker under 2K?" Well I found this link today also. wow under $1100 for new stroker kit at the price I am sure a number of these will go? Those guys are a bunch of real enthusiasts at Performance Nissan. I did a lot of business with them in my 350z days. Didn't realize they had branched to the earlier stuff too! I highly recommend them!

Eric Posted October 20, 2005 Author Share Posted October 20, 2005 whats the size diff between the l28 and l24 rods? that stroker kit says it uses l24 rods. Quote Link to comment Share on other sites More sharing options...
NZeder Posted October 20, 2005 Share Posted October 20, 2005 whats the size diff between the l28 and l24 rods? that stroker kit says it uses l24 rods. L28 = 130.3mm C-2-C L24 = 133mm C-2-C L20et rods I believe are also 133mm C-2-C (this is what the Japanese use to build 3.1, I will know more when I pull my L20et to bids - some of the L20a also use 133mm C-2-C I believe) If you have not heard of a L20et don't worry it is a JDM engine that we also get here in NZ (shares a lot of parts with the L28et ie exhaust manifold, dizzy (some have a different model), oil pump, down pipe that is about it) Cheers Mike Quote Link to comment Share on other sites More sharing options...
Eric Posted October 20, 2005 Author Share Posted October 20, 2005 ok. does the L28 disel crank provide a longer stroke than stock? that makes sence since it's in a stroker kit. cause i was thinkin, just get the l24 rods and the disel crank and save some bucks and get just a bit more power rather than addin the bore aswell. is that a good idea?

Dnaught14 Posted October 21, 2005 Share Posted October 21, 2005 Yes and no. Its the kind of thing where you are upping your displacement by very few cc's. With the maybe 100cc's gained your talking about less than a 15hp gain. I think the regular l28 setup is about 2780 (estimate) and if you change the crank and rods it puts you at about 2850 (estimate). Do a search, someone on this site has a displacment calculator with tons of potential combinations that you can select rods, pistons, blocks, cam, etc.. Regardless, if you are going to take your whole engine apart to get a little bit more displacment you might as well get it bored out and go all the way to 3.0 or 3.1. But thats my oppinion, so take it as a grain of salt. Quote Link to comment Share on other sites More sharing options...
