hey guys little by little I have been posting trying to get more info but to tell you the truth I’m still a bit lost. I want to do as much as I can while the motor is outside of the car it’s a rb25det. I have a list of things I want to buy just wanted to make sure it’s right. I also posted the price’s to see what you guys think and if you know where to get it cheaper just let me know.

Thanks in advanceAnthony

1. Greddy R33 RB25DET Intake Manifold 680.002. Greddy Timing Belt 125.003. OEM Water Pump 89.00 4. OEM oil pan (mine was crushed) 145.005. OEM oil pump 289.996.AM performance down pipe 325.00

I also want to get a clutch/flywheel but wasn't sure if it’s an N/A 300zx and if I can use the N/A pilot bearing. I just got confused.

OK yes just buy a WHOLE NA Z32 clutch kit.It all works.

The Flywheel is RB nothing else like it, I've heard old school L series. But I don't know.The Bolt pattern is KA and the size is VG.

USE THIS LINK!!!!!zerothread/110509

Your gonna need mounts, Driveshaft, 5spd stuff assuming your vert is still auto.I would do a gasket/seal kit on the motor.If you oil pan isn't that bad, use something and beat it out from the inside.

There's more I can't remember now, been soo long.

its a long story but to shorten it . my frined bought a rust bucket s13 and i put the rb in it for him but he never stared the motor. he never even put the harness that wiring specialties did and decied to never finsh so i bought it off him. he was a dumb *** and bought all this ricer stuff that he never needed. but he did buy alot the things that were good and i do need.

1. tophat mounts & drive shaft2. koyo radiator3. felxelite slim fans 4. aeromotive FPR5. intercooler no piping6. turbo timer w/harness

i also wanted to show the prices i found and wanted to see if they were ok or if anyone know cheaper places.

You might also want to think about ARP hardware, mainly headstuds. Also I didn't see a fuel pump in your list.

You don't need an oil cooler unless you're running 400+ hp or so. Also, other things attribute to high oil temperatures such as bad bearings, insufficient cooling, ect.. Basically if you take care of what you should in the build up you shouldn't need to.

He's right but as you can see other issues can cause your oil temp to rise so'd i keep one in mind for the near future as one of those "Needed" Parts regardless of HP in my book.
