HUD SR swap

[nzmoman]

Im just starting to build my third 240. this one is going to be a blacktop coupe but the chassis has HUD. Will I be able to keep this system when doing the swap?

If so, is the wiring going to be much different?

I already have plenty of 2nd gen s13 gauge clusters, but I want the HUD!

[S13240]

HUD unit has nothing to do with the swap.

I have a '91 SR powered coupe w/HUD and it would flawlessly. The only problem is if the coupe is a 89 or 90. The TACH won't work because its for a SOHC setup. Good luck!

[nzmoman]

your gauge cluster has everything to do with the swap.

what sucks most, is that its and 89.

Thanks for your input folks!

I appreciate it. If you can get me a 91-94 HUD gauge cluster call me

678.468.4015

For the record I didn't say gauge cluster...I said HUD unit has nothing to do with the swap. What you're talking about is the tachometer only...the HUD itself will still work whether it was an 89-90 or 91-94.

[driftin_sr20det]

Hell if you could find a shot HUD cluster for cheap you could probably swap the tach from that one and put it in your cluster.... Just a thought though. Or make some kind of custom tach setup in the stock position, that would be sweet too.

[nzmoman]

S13240 --- meant to say gauge cluster because performing a swap with anything not working (except the ac) is something I dont do.Besides, I'd never drive a car with a swapped motor....a swapped performance motor without a tach. I need the tach more than I need the speedo, and I refuse to put one of those huge ricer looking gauges on my dash when I can have a working factory made unit, but because the car is has HUD I figured Id try to keep it...why not?

A shot HUD cluster is definately the way to go thanks fellas

[S13240]

Hehe...it's cool. Definitely the way to go..honestly from my experience, get a jdm gauge cluster from an sr20 and just swap in the tachometer into your hud cluster. The analog tachometer won't fit perfectly into the HUD cluster, but still works with minimal trimming. Did this on my previous s13 coupe.

[nzmoman]

now that is an idea that I really need to go for...a true redline

[drifter_for_life06]

its funny though when people watch you "over-rev" when you know you're not

[nzmoman]

i never run my SR past 2500 RPM is a safety measure

[nzmoman]

FYIthat was not a direct swap.

the 89 tach is shaped different and is smaller. In order for it to work you have to use the face off the 89 or 90 and use the electronics from the newer models

[DrifterProdigy85]

i have my 89 Digital Cluster with a Silvia Tach in it. You have to trim a little tab off one end to make it fit down in the tach area. Some of the outside of the tach is hidden but the rpm numbers and increments are still visible. Everything works perfectly fine. Digi read out stops at 125mph which kind of sucks. You guys are making it sound more problematic then it is.

[inertiadrft]

I also did the tach swap on the "digital cluster" I used the tach from a jdm cluster, I trimmed the edges and installed it, it works perfect... I have a spare dohc tach but I understand you need it now and im in cali...just go to the junk yard and find a dohc cluster and pull the tach out........

[DrifterProdigy85]

if you swap in the Silvia tach. make sure the tach is from an SR20 silvia and not a CA18 silvia. i bought a cluster off ebay that claimed it was from SR silvia and it was from a CA silvia and wouldnt work. they even sent me a 2nd cluster that was a CA also that wouldnt work again. A way to tell between CA and SR clusters are the redlines. both redline at 7500 but the CA has a dashed warning area similar to a SOHC tach where the SR just has the redline at 7500.

humm, thats good to know.....

when I did it is wasnt as easy as shaving the edges, after I did shave the edges and install it the tack plate was bent still and the tick marks and numbers where misaligned. The newer tach plate could not show all the numbers and the needle didnt fit properly,

so in essence, it was more than what I was told I would have to do. which is a simple informative statement for anyone who may be trying the same thing reading this thread. The needles from the two clusters where not interchangable with the gauge bezel so I HAD to switch the tach faceplate in order to use this cluster.

I dont know about the silvia tach but that is how this one worked and it took more than just trimming, also it may have something to do with me going from a HUD tach to an analog tach?

Inertiadrft-sadly the junk yards around me have already beens scavenged by Nissan lovers, all the Z car and all the sx cars are stripped of all the good stuff,

[S13240]

Sorry you ran into trouble, it was a simple trimming job for my sr tach into the ka hud cluster.

[wannawangan]

Ben. You got mail about the T25 turbo. You can send it to me now as you have been paid.

Thanks!

[DrifterProdigy85]

it was a simple trim here as well. Right were the 6500-7000rpm plastic edge needed to be shaved down just enough to clear the plastic from the cluster itself. this was a silvia tach also. Took all but 5 minutes to do, 3 of those minutes were finding the damn scissors. sorry you had problems.

so if i buy a 91 hud tach would work? i have a sr powered 1989 s13.

recently my hud stoped at zero? still illuminates but it just stands at zer0? any ideas??
