Um... Hi.. Welcome to NICO! As stated above... the search button is your friend.

Ebay is also your friend!

You will be able to find a RB20 clutch pretty easily on ebay. Here's a nice stage 3 clutch kit.. http://cgi.ebay.com/ebaymotors...QrdZ1

As for your ECU... are you sure you have a RB25 ecu? I wouldn't think the car would run at all on that? But I could be wrong as I've never tried it. More than likely your problem with idle is caused by a dirty/stuck AAC valve and/or improperly set TPS sensor. I'd work on those first before spending moeny on an ECU.

Keep your eyes on the classifieds sticky on the top of this forum.. you'll probably find an ECU on there.

No AC is normal. No power steering is common. No heat???!!! That is very strange? Are you sure the heater core isn't removed or blocked off? Do you know if the water pump has been replaced?

Who did you buy the engine from? Who did the swap?

Heater core lines probably weren't hooked up (just looped together). Look for the FSM on the stickied posts and look which lines need to be reconnected to the stock heater core.

AC will not work... good luck on that one. You need to research that one yourself, then hit up a good AC shop for options. Very few people have AC here, like ten.

Search and read your a$$ off!

No ac lines is no hp loss it's like a 2 horse power gain.

yeah, im running a RPS street clutch for a NA 300z. works great and easy to findnow for lightweight flywheels you can't use a 300z because of the crank bolt pattern. nengun.com has some nice jun flywheels though

I have the RPS Max 6-puck sprung clutch and it is easy to operate too. I was shocked at how light the pedal is considering it is rated to 550 ft lbs of torque.

sorry i've been gone so long, computer is swapped now, it runs like a champ. heater hose is looped, and didn't know if there was a reason besides lazyness for that, and i was planning on the 300zx clutch, but tophat said the br clutch was WAY better.........but 200 bucks more. i am searching the forums as this is not my first forum (i am VERY big on the focus) but this i smy daily driver and didn't have time so i had to ask a lot of retard questions real fast.
