i tried searching but cant find what im looking for

im buying the apexi ax5370-p25 turbo kit that is advertised on here. http://www.skylinesaustralia.com/forums/Ap...-S-t226760.html

it comes with all the lines etc i believe.

its going to replace a rb25 turbo on my r32 rb20.

if i decide to do the install myself its all got to go smoothly & be a 1 weekend job, so im looking to get some info on the oil & water lines before i start.

where does the oil feed line from the top of the turbo go to on the block? is it easy to get to?

i think i can see 1 water line go from the turbo to around the back of the head, looks to be a bit tight in there for room..

where does the other water line connect to from the turbo? is that one easy to get to?

thanks

thanks for your reply, yeah i saw yur thread looking for similar help.

a spacer, yeah i just noticed my rb35 turb is just touching the stock mani heat sheild, so i was wondering about that..

did yours come with the apxi lines? if so does it connect to that water line at the back of the head?

what about the other lines are they easy?

hi Adrian

hi just found this pic of yur turbo, i can see where you have ground down the comp cover a bit for clearance, but i cant really see the spacer?

is it in that pic? cause the studs look like they are poking thru the flange/nuts, as much as my rb25 turbo?

cheers

haha yeh there is a 5mm spacer.. had to c! but was just enough to push it out so i didnt have to grind too much away!

its more the fact of clearing the comp cover than were the manifold joins!

yeah i understand what the spacer is for, but in that pic i can see the turbine t3 flange, gasket & what looks like the exhaust manifold flange - or is the 2nd gasket & 5mm spacer there?

also the studs have about the same amount of thread showing as my stock setup (suggesting no 5mm spacer?)

cheers

4k sounds about right from me guestimating from other charts ive seen that read road speed not revs (around 100kmp/h in 4th gear)

tbh 280hp atw at 17psi sounds a bit low to me, but could be the dyno or other factors?

im making 250 now & im hoping for 50+hp more not just 30?

are you running a cat & what dump is it?

cheers

      Is r33 gtr steering wheel the same as the gtst?

      By PotatoCake · Posted

      The steering wheel on my 97 s3 gtr is a little bit worn out, so im on the hunt for something mint. I notice that this type of steering wheel is on several other nissan's of the era.  Does anyone know if their all identical, or are there slight differences? I feel like gtr tax applies to anyone selling one, but if it comes from any other car the price is much less, even though its the same design.  Chat gpt says the material for the gtr is slightly different and it says gtr on the wheel, but every pic ive seen it just says nissan.

      Ahh... it's an early RE5R01A box, that means the pinouts I gave are wrong (they were for the RE4R01A 4-speed box)... I'll have to dig around in my docs to see if I've got that schematic (they used the same gearbox plug, with the vacant pin wired to the direct drive clutch solenoid)...prolly hidden away in a supplement somewhere... ...there were 3 variants of the RE5R01A ~ this early schema was what we called the 'dumb' 5 speed ; it's what jatco called a 'medium duty' box, with torque holding up roughly ~200ft/lbs or so, which was good for NA from RB20/25DE and up to around VG30 output spec. With the RB25DET (and VG33/35 mills), the only options they had was the 4-speed 4AX00 box, which had been beefed up to handle the extra torque (primarily for the VG35, but it also suited the RB25DET mill and others)...and the RE4R03 box in large 4WDs a lot of the time... ...the next variant of 5-speed was redesigned, stronger, and 'smart'...first ones had external TCU with internal (on valvebody) Shift Control Unit, pressure switches, and 2 x TSS...and the last ones had internal TCU+SCU setup, with CANbus control etc etc. @DRoc81 On the RHS of the box towards the rear, there should be a stamped silver ID tag -- what's the model number? Oh...and with the early 5-speeds, the torque converter control solenoid assembly should be replaced as well (31940-60X00)...it's a bit Murphy's Law ....if one has failed, bet on the rest not being far behind ...
