need advice

I picked up a 4G64 6-bolt crank from a 1995 galant. the same yard has a 6-bolt 2.0 that was missing crank, but had the rods and pistons. Im wanting to build a street class time attack car. I was told i could use the 6-bolt rods and just get some wiseco pistons. question is if i do this, how long will these rods hold in the event of road racing/time attack? I'm looking at a maximum of 550 flywheel hp, and this cars never going to see over 7,300 RPM. I dont have a lot of money for the engine, there's much needed suspension thats taking most of my budget.

If the 2.4 is truly a 95 than it would of been a 7 bolt. For what you are trying to do i would just build a stock 6 bolt bottom end with arp rod bolts and 2g pistons.

Is your current engine in need of a rebuild?

I considered this as well, but I need low end torque and a broad power band. 2.3 liters is going to help spool up the GT3076 turbo at a lower rpm. These turbos make good power, on an RB powered 240SX here in phoenix we saw 415WHP at 4000 RPM on 18 PSI. Forced Performance website on a customer testimonial says the same. I know RB25's are six cylinders, but I will be just .2 liters shy from the displacement on the 240SX.
