OlderThanMe Posted October 13, 2006 Share Posted October 13, 2006 well I have decided to do something different. L26 turbo... I have a couple things that I would need to figure out how to do. I would need to o-ring the block. Now the L26 P30 block is notched for the bigger valves so I would have to get an oring larger than the notched section. I am thinking of boring the block .040" bigger to get to 2630cc instead of the stock 2560cc. I'm looking at some nice custom forged JE pistons from racetep. Compression ratio will be about 8.1:1 or 8.3:1. I should be pushing near 10psi by the end of next summer with megasquirt. I sort of have a 270hp cap by my 225mm Spec stage 2+ clutch which I will upgrade later. The motor was probably making in the 180-190 HP range but I would like to be at a conservative 250hp with the ability to make over 300 with a stronger clutch and higher boost. The car will be a daily driver and a good roll cage, kirkey road racing seats and 4 point belts will be going in with the motor since I will need the protection. Some of you may have seen my thread about breaking my jaw into 4-5 pieces from wrecking my bicycle so I am going to take every precaution to make my car safe. Things to do: o-ring block, 1. bore block over .040"(1mm), 2. decide on forged pistons, 3. get proper head gasket, 4. have cylinder head worked over and opened up, 5. build my turbo system, 6. 3.5" or twin 2.25" exhaust, 7. reassemble engine with all new ARP hardware including head studs and Clevite 77 bearings Quote Link to comment Share on other sites More sharing options...
240zV8 Posted October 13, 2006 Share Posted October 13, 2006 should be a fun car once ur done, and not to much power that u will break ur jaw when put ur foot down...lol jk.... Isn't 3" enough exhaust to get the turbo stable with that power? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted October 13, 2006 Author Share Posted October 13, 2006 3" should be enough maybe...There will be more than one turbo though... a stock or slightly modified nissan T3 and a holset hy35w...placed consecutively placed and not side by side. Should start boosting at 2500 and then bypass to the holset once the T3 spools up. Don't worry about the T3 limiting the holset...I have a way around it..
