Guest alfman240z Posted June 2, 2003 Share Posted June 2, 2003 i know this has probably been answered a few times but the searching for hours and watery eyes are getting to me so i decided to post a new thread. i was wondering what i need to run a 12-13 sec l28et in a 71 240z. currently i have the stock engine but searching for a l28et. what would i need to do? as much as posssible stay with stock internals and keep cost affordable (i know 12-13 second are the most "afforadale" cars but as affordable as possible) any and all help is appreiated. how do make custom IC piping? and where and how do i mount it?

SleeperZ Posted June 2, 2003 Share Posted June 2, 2003 Stock motor: Upgraded exhaust, fuel system, turbo, intercooler and a reliable engine management system. Here are some posted pictures of intercooler piping. http://www.hybridz.org/phpBB2/viewtopic.php?t=21413 That's for solid twelves. You can run 13s on stock everything, just up the boost with an intercooler (or NOT, check out Jersey...) Quote Link to comment Share on other sites More sharing options...
yo2001 Posted June 2, 2003 Share Posted June 2, 2003 Yeah, it won't take much HP to get a 240Z in 13's to 12's. Good luck Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 2, 2003 Share Posted June 2, 2003 There is a thread about this somewhere from recently. Real recent. Not sure where though. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 2, 2003 Share Posted June 2, 2003 There is a thread about this somewhere from recently. Real recent. Not sure where though. You might be thinking about the Nissan PU with the VG30ET. He was asking what it would take to get into the 12s, and it's basically the same thing. http://www.hybridz.org/phpBB2/viewtopic.php?t=21595 Quote Link to comment Share on other sites More sharing options...
fl327 Posted June 2, 2003 Share Posted June 2, 2003 check that Jersey guy out, he ran a low 13 with no ic and 10psi on stock everything in a 240z, man that extra 400 some odd lbs from the 280z-zx is really starting to show. that low 13 is one good piece of drivin.. i know guys that dyno 280-300hp to the wheels with hybrid turbos and a bunch more stuff that run the exact same times, and mph!!!!! if it werent for the video-id holler BS in a minute. I basically walked my car into a high 14, no IC and 7psi in 83 degree weather, and a hatch full of tools, a 3 ton jack, 10inch bazooka sub, and clothes. i know a mid 14 is possible once i empty that stuff out, and a low 14 is possible when i strap the DR's on one time and launch the sucker, im looking for a mid-high 13 and close to 100mph once i turn up boost, now I have FMIC. ill officially close the summer session on this car when i do that, and go into almost strictly body work, and make a 70s car, well, look like a 70s car. in a 240z, if youre not afraid to flog it and you do your install right and youre efi is rockin, it looks like 12s should be kinda easy with stock management running well, see how long you can keep the positive cable attached.

Guest Zcarsmakemyheadhurt Posted June 6, 2003 Share Posted June 6, 2003 If you can get the factory ECM to work well on the car, pull clean to 6000rpm. I would use a hi-pressure fuel pump (MSD2225 $100.00) A boost sensitive fuel regulator that brings up pressure "on boost" and maybe a small TO4B upgrade A "S" trim. A intercooler would be a good idea but if you keep it on race gas boosting between 14-16psi I'll bet 13 sec ET's would be a easy task. You got to get the fuel pressure just right to keep it rich and safe timing is a must. If you budget doesnt allow for a turbo upgrade boost the stock T3 up C17 race fuel. The race fuel is gonna keep you from kiling the egine a intercooler will help you run more timing and safer boost, but race gas is a good idea and a secret to keeping it alive. If you need help on the parts let me know. Alex C AIM:boostmyride Quote Link to comment Share on other sites More sharing options...
