Black5spdZ Posted September 22, 2004 Report Posted September 22, 2004 Will the L67 bolt up to the 284 if i use like a flywheel out of a 3800 5spd f-body. I would love to put this in my Z34 but i want to keep it a 5spd, so if this douesn't work is it worh porting and polishing the upper and lower intakes? Quote
BadBuick Posted September 22, 2004 Report Posted September 22, 2004 Not sure about the flywheel. But depending on what you do with L67 as far as mods, it will more than likely blow that Getrag apart. Quote
99RegalGS Posted September 22, 2004 Report Posted September 22, 2004 You need to use a F-Body 3800 flywheel and machine it to work with the FWD 5 speed. Go to http://www.L67swap.com there's more info over there. Quote
Black5spdZ Posted September 22, 2004 Author Report Posted September 22, 2004 does anyone know how much hp the tranny would hold safely, but the 284 will bolt up if i get the correct flywheel? Quote
stockgp Posted September 22, 2004 Report Posted September 22, 2004 i think the guys on l67swap.com said you could use the 284 as long as you drove it easy. Quote
gp90se Posted September 22, 2004 Report Posted September 22, 2004 the first time you goto shift it anywhere near redline, goodbye 5 speed. theres a fiero company that makes flywheels to do it and yes it will bolt on, but I dont see it holding up for long Quote
Black5spdZ Posted September 23, 2004 Author Report Posted September 23, 2004 does anyone make hardened tranny parts as if it isnt hard enough to find stock???? Quote

Black5spdZ Posted September 23, 2004 Author Report Posted September 23, 2004 thats what i thought but now that i think about it the gearing might be to short the L67 redlines at 5500, does anyone know of a w-body with a 5sodl67? Quote
99RegalGS Posted September 23, 2004 Report Posted September 23, 2004 It's not so much the horsepower, it's the torque. The series 2 L67 has 65 more ft lbs, and if the person mods the engine it will be over 300 quickly. Combine that with a 3300 lb car and the tranny won't like it. Quote
Black5spdZ Posted September 23, 2004 Author Report Posted September 23, 2004 thats true i didn't really think about that. I am going to talk to a good buddy of mine at a tranny place and see if he can strengthen or harden the gears and modify the synchros to handle that kind of power because i would like to be able to get on it and not have to worry about blowing chunks.

brianteel Posted September 23, 2004 Report Posted September 23, 2004 i am almost done with mine. I just need to get a 282 trans clutch and flywheel and the car will be good to go. My L67 redlines at 6500. easy to move the redline if you change the springs Quote
