Hi everyone!!!

I currently have a '71 240Z w/a turbocharged stroker. About 2 1/2 years ago, I built the bottom end w/LD28 crank and 1mm over pistons. The bottom end needs rebuilding now because of much turbo abuse and I have a delemma:

Do you guys (and gals) think I should redo the stroker or should I forget it and just do an L28? Do yaall think that there would be a significant difference between the stock L28 and the L28 3.0L when using the turbo? The car did a [email protected] the way I had it. Please let me know what you all think.

[240Z Turbo]

I would go with the non-stroker crank. My car was beating 12.4 cars with 1mm overbore and 19 psi of boost. I am rebuilding my motor next week with L-28 crank, forged rods, JE 7:1 forged pistons, 2mm oversized SS intake valves, 3mm oversized SS exhaust valves, 62-1 T3/T04E, cam and some other mods. This will be a low 11 second car with 500+ hp. I have seen guys run 12.5 with the stock turbo bottom end.

Ive always heard there is no replacement for displacement, but isn't a stroker motor more of a torque machine than a high revving sports car. Turbocharging increases torque as much as horse power so it seems the stroker would be faster off the line.

At any rate if you already have the stroker crank, why not use it.

Good advise sell your stroker crank (should be able to get $300), put this money towards a quality turbo or intercooler .
