93 octane

and probably either 110/6 octane.

thanks.

 

Depends on your application. Mazda 3.9 is very popular. They are about $500 extra for a diff rebuild. But they give a very desirable amount of time in each gear.

 

What numbers are you asking about?

 

it all depends on what you are going to do with the car and how hard you will drive it. plenty have survived on oem stock original diff/trans combo up to 500-550 whp or about 350-400wtq. i am still on my original oem trans/diff after 20k boosted miles. 450/300 for power. but i dont slam gears are laucnh the car.

I'm at 500whp and nm. I drive the car somteimes to work, for spirited driving, and some trackdays (road track, not drag). I don't launch or slam gears, but I drive what most people say is relatively hard. I still have my stock trans with ~118 000 miles, but I have literally crushed the gears in 2 diffs under highway pulls (not launching or drifting etc). I think both were 2nd gear.

Are you referring to a stage 2 clutch? Competition Clutch Stage 2 - Street Series 2100 Clutch Kit has spec that are good up to 300ftlbs of torque. This would not cover you for launching the car. But good for street or track. I bought one and will be running 420whp and 260ftlbs of torque.

 

estimated hp and if i upgrade the fuel pump will that yield higher numbers?

 

Yes. You can run an ethanol sensor/switch fuels dynamically. EMS-4 uses the same software as v2 (AEMTuner).

 

Hey guys so I just threw my turbo manifold up, and my A/C lines are sitting right on my manifold... :'(
So I'll be needing some custom lines, I've looked around and there seems to be a couple different ones, i also noticed that theres a sponsor here that sells them.

Do you guys recommend any specific ones?
Thanks.

 

^^^ Ghettocrx a.c. relocation lines. If I had to relocate mine, I'd buy these.
