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)......

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
