i was wondering if any one can help me out with some info.......

i actually own a 1966 prince skyline gt-b. it use to have a l28 with twin carbs till about 3 months ago when the top let go.

no i am almost finished completing a RB20DET engine conversion....... only catch..... i need to know anbot the pulse signal the speedo gives to the computer..... i wont to try and use the orginal speedo.... and fit a pulse generator like the ones the use for peed alerts.

The Question is: does the speedo give out a pulsing power feed to the computer or does the computer give the speedo a power feed and the speedo turnes that to a pulsing earth feed....... any help would be greatly appreciacted in this matter. Cheers...... :P

Speedo is mechanically driven off the gearbox.

If you mean the tacho, then the ECU sends the signal to the tacho, presumably based on the number of impulses it gets from the CAS.

Try a guy on here by the name of prince....he has a C110 gt ex with an rb20 running carbs...yes...carbs.....if anyone knows for sure i'd bet he does

Good call Jason.

Pete, "Prince" is Ray. You met him at Beechworth. White '73 coupe with the rb20. If you have no luck here, You should be able to get through to him via the Prince register.

Don't forget to keep us classic tragics :) up to date with the progress.

Can you make it to Goulburn??:whatsthat

Cheers,

Jim.

But it sounded so nice with the L28 in it!

Yes, I've seen you around Adelaide - I own that red DR30 that was in front of you on North Terrace a few months back...

it did sound nice ben with the l28 in it... but when the head went bang..... and i couldnt find the head i wanted.... ( p79, p90 or a l20et head)... my mate decide i should upgrade.... and wot better up grade than a sleepy looking prince with an rb20det? if ya wont a look at it here's my web page..

i look at it it will be quick and still keeping with the theme of a true skyline gt with a high performance 6cyl in it.

i look at it this way.... my car has been severely modified before i got it ( ie: big steel flares, l28, twin carbs large mags... and i mean from a 165-13 inch rims thats suppose to be on it to a 235-60 -15... wot more could i say.) i have improved it more with the new motor... volvo 4 spot calipers on the front bigh front mount intercooler hidden behind the grill . Painted from white to a nice purple and fixed the body.... now she will be a lil' weapon when she's back....

have to catch up sime time so you can have a look at it...

Pete...

Ps: maybe i be able to keep up efortlessly now with this conversion... if i can get the wheels to stick to the ground!

Guess what?

I've got a complete L20A head (requires recon) just lying around.

I've also got a welded, but otherwise bare N42, also lying around....

Still the RB20DET is a better way to do things.

Actually, looking at your car in its 'before' state, I reckon I had a look at it in a car yard down south in around 1995!

just found out that i do need signal for speed sensing for the ecu... now the question i need to ask is the signal a square wave...(negitavely earth) or saw tooth wave ( poistively earthed). if i can find out i might be able to use a pulse generator that they can fit speedo cable ( ones they use for retro fit of speed alerts on aftyermarket cars)......

      Neil's R33 Gts-t Build

      By Victory · Posted

      All I can say Duncan is good luck and I hope that Neil did not run any E85 in Cheryl. I have recently experienced the full spectrum of fuel tank issues in my R33's that had been caused by E85 and contaminated fuel. When you take the cover off the top of the tank and have a look inside you will get an understanding of how easy it will be. Best case situation is clean fuel with minimal contamination. My GTR was like this and it was a very simple operation to just grab the fuel pump carrier bracket and slide it up and out of the tank. My three GTS_T's had different levels of fuel contamination that was probably caused by E85 in the fuel.  In the worst case all of the metal components in the tank had rusted to the point where there were pieces of rusted metal swirling around in the tank. This required the removal of the exhaust, the tailshaft, the complete rear cradle and the fuel tank. The components in the tank were that rusted that it took days to get the fuel pump carrier and the mounting brackets out of the tank. When the tank was finally cleaned, everything inside the tank had to be replaced. With the tank all back together I could then reinstall it in the car along with everything else that had to come out. Good luck and I hope that you find a clean tank.

      It is a two door. It is black and also still has the OEM wheels and stereo. Exact model would be KR_R32RGFEL_SS According to GTR-Registry.com is a 2 Door Coupe; RB20DE; 2WD no HICAS; MT.F5; (11L) Projector Headlamps and Fog Lights; (12_) Electronic Active Full Auto Air Con (Climate Control); (13-14SS) V Selection -- Which seems to be accurate description of my variant. Will try to upload a few pictures soon. The OEM wheels look like the below image. Image is taken from the goo-net-exchange website.

      Welcome Gabriel. At least your car has a glorious RB and not the shitty CA18. As MBS206 mentioned all the good bits can be added later. Two doors or four?
