I have a r33 gt25t auto and I'm putting a r34 GTT manual transmission into it. What are these two holes for? I'm assuming 2 is for the dip stick and 1 is for a sensor? Is that correct? Thank you!

Looking at this diagram it appears that number 1 is a vehicle speed output:

Number 2 appears to just be plugged off with what appears to be a harness clip or something similar:

Where does the dipstick go then? What is the piece to the left of the #2 I have noted? Do you know what the brown and white sets of wires are? I believe one set is for neutral and one set is reverse but I'm not sure which is which. Then since they are both just solid colors, which is ground........

By chance do you know if a 240sx clutch pedal will fit smoothly in an r33 gt25t?

Thank you for your reply!

Dipstick? In a manual transmission?

It's not an auto.

There are 2x switches. Reverse and neutral. These are the ones up high on the box. Speed sensor goes in down low. All behind the centreplate. The port up high in front of the centreplate is the breather.

#1 is your speed drive. 

#2 I am fairly confident is the ball detent that holds the shifter in gear by placing pressure on the shaft.  It should have a spring and a ball :)

 

Also note the balls are different sizes between the box's, mixing and matching is bad.

neutral switch to the rear, reverse switch to the front

that other cover where the breather support goes though, you need to confirm what goes there. CH-80 in the GTR manual suggests there should be a spring and interlock ball in there, if so you need to confirm and put them in there.

Okay, the transmission did come with something for #2, so hopefully that's just sorted out.

Since my car is an r33 gt25t and was an automatic, for #1 am I able to wire the auto speedo wires to the manual r34 speedo wires? (looks like I have to buy a r34 speedo sensor?).

For the reverse and neutral wires I am tapping into this pictures green, white and black.

      Started sifting thru my brakes to decide which ones I will run on Clem   Made me think I should just put them all on Silver...for when brake fade just isn't an option   Should be able to bump rotor up from 343x32 to 348x36 off Supra. Not sure if the Supra annulus is right for the Alcons or APs but trying g to find a used Supra\M4 rotor to test fit The Alcons seem to gain 1-2mm clearance which all helps

      HR34 GT speedo issue

      By joshuaho96 · Posted

      Probably speedometer itself if the odometer is ticking. If the needle is stuck from a bit of grease or something that can cause it to stay at 0. Or a cracked solder joint in the speedometer can do it too.

      Thanks Fella’s   to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you?   A) R34 GTT box   B) CD00#?  I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way

      Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate
