droogie Posted January 5, 2007 Share Posted January 5, 2007 aight guys, ive been searching around this forum for a while now and i was wondering how feasible it would be to accomplish 200 horsepower at the crank with the l26 engine, e88 head, early s.u.'s, and flat top pistons. i know the easier way to accomplish this would be to acquire an l28 with the p90 head and do the corresponding mods but all i want is a quick 260z without having to swap engines. im not at any point ready to start this project right away but i would greatly appreciate the input for future reference. thanks guys droogie Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted January 5, 2007 Share Posted January 5, 2007 I should be around 175 hp with my L26 before long... L26 bottom end Maxima N47 head L24 flattop pistons 10.25:1 CR roundtop SUs(eek! restrictive!) mystery header, 2.5" exhaust My L26 already had the 240Z flattop pistons in it so all I am doing is swapping the MN47 to hike the compression ratio. I am only doing this because I got that head for a steal($39!) and I already have everything else. I am still going to build a hot turbo motor down the road but this will have to do for now because it is what I have. Quote Link to comment Share on other sites More sharing options...
katman Posted January 5, 2007 Share Posted January 5, 2007 208 crank hp (that'd be real, east coast, SAE numbers) with an L24 ITS engine: stock SU's (basically), stock cam (basically), stock ITS prepped E31 head, stock +1mm blueprinted bottom end (basically), custom headers and carb needles. All it takes is a $8000 check to Sunbelt. No problemo. Quote Link to comment Share on other sites More sharing options...
johnc Posted January 5, 2007 Share Posted January 5, 2007 Or you can do the bolt-on horsepower thing and get way more then 200hp: Exhaust - 10 hp Headers - 10 hp N36 intake - 10 hp K&N Filters - 10 hp Cam - 10 hp Electronic Ignition - 10 hp 10mm Plug Wires - 10 hp Electric fans - 10 hp Aluminum Flyweel - 10 hp Centerforce Cltuch - 10 hp That's a 250 hp L6 engine right there...

SHO-Z Posted January 5, 2007 Share Posted January 5, 2007 Without having to change out the cam and getting into the internals of the engine. I would fab a supercharger set up like the one on this TR6. I think this set up could make your 200 hp. Quote Link to comment Share on other sites More sharing options...

piper5177 Posted January 6, 2007 Share Posted January 6, 2007 I think I am at at least 200 flywheel with my setup, though it wasn't cheap. E31 head tripple webbers setup for 6500 RPM peak HP stage 3 cam (Schneider .460" 270/280) port matched Canon intake flat top forged pistons .030" overbore P&B crank 12 lb flywheel MSA 6-1 header 2.5" mandrel bend exhaust with Dynomax bullet and Magnaflow round race can straight through Crane Fireball Hi-6 digital ignition on an E12-80 module I get 160-165 on 91 octane at the wheels (got to be around 200 flywheel). I'm not going to pull it out to test flywheel HP. I love this engine setup, just enough torque down low and easily revs to 7000. I could probably get more with headwork but it runs so good that I don't want to mess with it anymore and I wouldn't notice the few extra ponies on the street. When this engine dies (less than 5000 miles on it) I'm going RB25 anyway unless I get the horsepower bug up my ass. Quote Link to comment Share on other sites More sharing options...
Tony D Posted January 6, 2007 Share Posted January 6, 2007 205 RWHP on an L20A, so Crank HP on an L26 should be, as stated above "No Problemo" And that's on the same dyno John C used dynoing his Rusty Old Datsun (Thanks for the recomendation, JC, they are a great bunch of guys!) So that's "West Coast" horsepower... how that equates to SAE East Coast Horsepower, I don't know... But the ITS Stock engine is a good point! And everybody knows a cam is good for at least 30 HP "to the rear wheels" John! ;^P Quote Link to comment Share on other sites More sharing options...
katman Posted January 7, 2007 Share Posted January 7, 2007 East Coast hp is a jab at Rebombo, er, I mean Rebello, whose engines always made way more hp on his "West Coast dyno" than they did on Sunbelt's "East Coast" dyno. Quote Link to comment Share on other sites More sharing options...
Challenger Posted January 7, 2007 Share Posted January 7, 2007 L26's gross power (flywheel) is about 150 i think, an L28 is 170 so I think it gonna be somewhat hard to get 200 hp Na without spending a lot on a L26. Several Nos stickers and a Viynl scratch mark helps on power too. Quote Link to comment Share on other sites More sharing options...
droogie Posted January 7, 2007 Author Share Posted January 7, 2007 Several Nos stickers and a Viynl scratch mark helps on power too. yeah i was thinking about that...slap some nos stickers and a rediculous wing on the rear end and i should fly right?! haha its just food for thought now. i would love to get a quick z going but right now im still trying to bring her back from the grave. i appreciate all the responses and ill leave you guys with a few pics... droogie (im cheap...17 bucks on a chain and 4*4 beats 200 for a cherry picker) Quote Link to comment Share on other sites More sharing options...

OlderThanMe Posted January 8, 2007 Share Posted January 8, 2007 The MN47 will bolt onto the L26 block...I'm not sure about a L24 block though as the L24 block does not have valve reliefs cut into the block. The L24E I pulled my MN47 from had small reliefs cut into the block. My L26 block has plenty of room for the smaller MN47 valves... Quote Link to comment Share on other sites More sharing options...
