[240z L28et Build]

My engine is a 2.8 F54 block bored to 88 mm, diesel crank offset ground to 85mm stroke, custom JE pistons, custom Eagle H beam rods, P90 head ported by Gerolomy flowing 214 cfm @.550 lift Intake, 153 cfm @ .550 lift Exhaust, custom Isky cam .540 lift both sides 270 duration both sides 109 lobe center, custom turbo exhaust manifold, Garrett GTX35R T4 .82, TWM ITB’s, TEC3r engine management, 10 lb aluminum flywheel, SPEC stage 5 double clamp clutch, T5 tranny with a G Force gear set. The engine is surprisingly docile with virtually no lag. It's important that everything is sized and working together and the beast tuned correctly. I run anywhere from 14 to 21 psi on the street.  The key to hp and torque is air flow and with this set up the engine makes so much power at 18psi that I rarely run up to 21 on the street even with sticky 275's on the rear.  If you want more specific info pm me.

 

wow impressive, do you have any pictures or videos of this car online? I would love to see it.

pm me your info and if you are on Facebook there is a Z group local here in lower NYC area.

 

For some reason I can't PM you. I keep receiving an error.

 

 

450+ rwhp is very doable in an 2.8 L series motor without meth injection if it's tuned correctly. I'm pushing 600...no meth inj. To get good reliable rwhp it's all about air flow. My only suggestions in addition to your proposed set up would to look into a good turbo cam (lots of posts here on turbo cams) focus on lift not duration, lower the static compression to somewhere around 7.5-7.8, and port the stock turbo exhaust manifold especially where 1-2-3-4 converge. I don't know Holset turbos.  I work with Garrett. Just make sure your turbo supports your hp targets. Next steps would include a drivetrain that safely handles 450+ rwhp, lightened/aluminum flywheel, clutch, trans, larger driveshaft with solid u-joints (Spicer 1310), and upgraded rear axles, cv's etc. 

 

Good luck and have fun.

 

Interesting, thanks for the info. Would you mind telling me more about your setup?

Where in NY are you?

I see you're from the bronx

I have yet to find much of a Z community around here

Hi all,

 

This is my first post on this forum. I have a 1970 240z that I am currently working. I am picking up an L28et as well as a 5 speed transmission from a 1983 280zx. I am looking to get a good amount of power out of this engine (around 450+ whp). After hours of research I have come up with the following

 

L28et

P90 head- port and polish

dewebbed intake manifold

JE forged flat top pistons (raise compression to 8:5:1)

Injector 550cc 

Holset hx35 turbo

Fuel rail? Depends what's out there

Stand alone megasquirt ecu

Differential 3.9 or 4.11 r180

3" exhaust

 

I know I am missing a few things but I just wanted to get your guys input. I am new to these engines so please bear with me. Thanks.

[WTB 240z shell/roller northeast area]

I bought my first 240z not too long ago and found out it was far too rusted. Im looking for a 240z shell/roller preferably with no interior and minimal rust. The condition of the paint does not matter to me as I plan on doing a respray. If anyone is selling or knows someone who is selling a solid 240z shell/roller within 150-200 miles of new york city please let me know asap. I want to get her on the road next summer.

 

please pm me or email me at yaseen2492@gmail.com

any help would be greatly appreciated

thanks!
