So I've been given the opportunity to put in an OS Giken Twin Plate clutch in my R32 GTS4. I'm making about 200awkw, so nothing spectacular power wise. I'm getting it cheap so its almost worthwhile considering.

What I want to know is that other than strong muscular pain in the leg that it causes while shifting, is it hard to use in a daily driver? Do any of you use it in a daily?

yeah its the STR2CD jobber. The product specs say its for street use, but I've never met anyone running one in their daily, hence the hesitation. Don't want to regret putting it in afterwards.

Harden up :D

Mansoor (rukus) has one and swears by it - he reckons its easy to use

Shaun (sh@un) had the exedy twin and found it ok, but could be better

I say go for it :unsure:

so for question number 2... Theoretically the clutch and flywheel need to be balanced so that its not too heavy as a whole or too light that the flywheel degrades. when you guys put the twinny in did you get the matching flywheel from OS Giken or did you get a standard flywheel lightened or a lighter flywheel from another manufacturer?

they all come with a flywheel monkey. you cannot use a twin plate with any other flywheel than what it comes with as the cage attaches to the flywheel.

BB is correct and they usualy have a mark on them (Like an arrow on the fly and the clutch) so you line them up . I use a Nismo twin, a little more user friendly than OS but is fine .

Use it! I have one too. Pleasure to use, never had any leg pain.

What model Nismo do you have wrxhoon? I have the chance to purchase a barely used Nismo twin to replace the OS when it runs out of meat(not very long)

Nismo Super Coppermix twin 640ps, I'm using the Nismo larger slave with it as well. With all twin plate clutches you must not ride them , if you do you will wear them out real quick .

Got an os twin as well and its fine for daily duties. The 20 box blew so a 25 item went in with a larger slave and its not very heavy at all.

I have more trouble getting in the other halfs N16 with stalling as I am used to the OS item with how much lighter it makes things as you only need a blip to take off.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
