Fuel and Drivetrain Suggestions - PTuning Turbo Setup
I have the Exedy Twin Disk and also the Blox quick release clutch master cylinder. The feel is fantastic. It is a little stiffer than stock, probably due in part to the short throw clutch master cylinder. Shifts are very quick and smooth with this combination. The only time I ever experience any clutch chatter is when RPMs are really low and I'm trying to slip the clutch too much to get moving in 1st gear, but that's my fault. I think its a great clutch for a high horsepower S2000.
Seems like high HP folks (500+) are either using the SOS or Exedy twin disk setups.
RAIN H8R suggested the SOS sport 400. Are there any other viable options that are not well over $1K or are others vouching for the SOS sport 400? I'm a proponent of doing it right, but if I can save the money and not spend another 1.5k on a clutch, I'd like to.
As always, appreciate you all.

For 400-500 whp, I can't see the benefit of a twin disk. SOS Sport 400 seems to be the best option short of the SOS twin disk. I've had a SOS twin disk in storage waiting to be installed for a few years now. The Sport 400 wasn't out when I got my twin disk, or I would have probably tried it first.
I've run aftermarket PP with OEM disk and a full aftermarket clutch (SPEC stage 2 kevlar rated for 425 ft-lbs). These had issues with noise, drivability, and capacity and made me dislike driving my car.
I haven't heard anything about the Exedy twin disk.
ID1300's + some variant of the Walbro 450 or similar are the way to go. Since you'll get a SOS clutch, just get their fuel pump kit and injectors while you're at it. I've never gotten anything other than great parts and service from SOS.

Welcome to the Ptuning club! I have GTX3582 G2 on my kit. Feel free to reach out to me with questions, I can also install everything for you if are interested.
Don't forget to shave the motor mount inserts before install.
Don't forget to use Mitsubishi EVO hard pipes for the coolant lines attached to the turbo.
ACT HDSS/OEM Disc will only hold 17psi (ask me how I know)
Thank me later:

Thank me later:
- remove the valve in the AP2 slave or buy the AP1 slave in conjunction with the following clutch
- SOS Sport 400 clutch (a little touchy on initial starts in 1st, but should hold 20-22 psi). Pedal feel is SOFTER than stock

- ID1300 if you plan to run 93 and e85, with a goal of approx 600whp on a dyno jet (80-85% duty cycle with 65% base fuel pressure)
- If you want more than 600whp, go with ID2000 and E85 only and you can run stock base fuel pressure
- Go with the Walbro 295 pump. It is the same body as the 450, but no check valve and flows significantly more fuel with 2 amps less draw.
- For a first timer, buy the SOS fuel pump relay kit, but swap out the relay to a different brand, they tend to fail.
- If you are experienced, buy the wire terminals and make your own kit.
That pump doesn't require a rewire and fits in the stock AP1 fuel carrier holder with no issues right? Appreciate the heads up!
hey bro, Is this the same pump we are talking about? https://www.summitracing.com/parts/vpn-gsc295/

I believe the 295 is the same as the 285, but minus the check valve for lower pressure drop and slightly higher flow rate.
I believe that these are both dimensionally the same as the Walbro 450.

Nope. That's a little pump. This is what he's talking about:

@Dustin, because the pump runs approximately 2 amps LOWER than the 285 *(does the 450 draw a lot of amps as well), a rewire is required correct? I really don't know how to do this and also don't want to melt factory wiring / start low grade fire hazards in the car. Do you have any suggestions for the rewire protocol? you said to ditch the fuse holder as well? Do you also have a fuel pressure regulator in your setup?
Bro! Thanks for clearing that up for me. Its the Hellcat pump + and the part number denotes 295.
