Anyone kno if the instrument clusters are swapable? i want the one with the higher MPH. But im confused to which one it is. I've heard the TII has the higher MPH and a boost guage, but all i see is that the they are the same. From what i kno, i have a NA S4 and it goes up to 140MPH and the S5 and S4 TII have 160MPH correct? Can someone clear this up for me? pics would be nice because i still havent seen the boost gauge that people have mentioned on the TII guage cluster.

CrypticApathy

any reason why? your not going to hit those speeds.

royaltrex7

if you look where the volt meter is on your s4 na the s4 tII has a boost gauge and accually the s4 na says 140 but has extra notches to hit 150

so then somethings is wrong with my cluster cause i have a T2 cluster and it only goes up to 140 heres the pics

royaltrex7

what year and what model is the cluster from?

Tokyo-RX7

I was lookin at clusters on ebay, and i didnt see the boost gauge. i guess they aernt real TII clusters. so its just the S5 cluster that goes to 160? Will the S5 cluster work as a replacement?
Why cant i hit 160? I've hit 140 before, dont see why i wont be able to go 160 after im done modding my car.

royaltrex7

i have the same problem i belive the s4 and s5 clusters are interchangable but only n/a to n/a and turbo to turbo for the boost and volt meter fact my car is an 88 but the late 88 that had the real minor changes with the idot cluster and guage cluster i believe thats all because my idiot area points towards me like the s5 but the guy i got the car from messed up the cluster and i replaced it with an 86 till i could find the correct one

Tokyo-RX7

i dont have a problem with mine, i just would like a cluster that hits 160 so when i hit that speed i wont have to guess how fast im goin.

royaltrex7

i know and i had purchased a reverse el glow guage kit for my car and it says it will work but the speedo is the 160 one with the 9000 red line and the fuel and temp guages are reversed like i said the cluster in mine is out of an 86 n/a but its supposed to have that style from what ive seen

Icemark

S4 clusters can be swapped with other S4 clusters, however S5 clusters wire differernt than S4 clusters and would need to have the wiring harnesses re-pined to make a S5 cluster work in a S4 car (or visa versa).

royaltrex7

so if you orriginally had an s5 cluster and it has an s4 cluster what would it do?

with the higher MPH speedo, say 160 versus 140 or 150, would the speed be off?or would it still be accurate.

Psygnosis7

The speedometer isn't exactly known for being accurate at those speeds, if you really want to know how fast your going, it'd probalby be better to get some sort of GPS unit.

royaltrex7

accually ive had people argue with me that its impossible to get any n/a fc to go faster than 130 (namely a guy here in my local area)

liv

^ stop listening to that guy

I can go 130 up hill in my 87 n/a

Icemark

I am not understanding your question. You have a S5 and you want to use a S4 cluster? or You have a S5 and a S4 cluster is in it and???

royaltrex7

i have the 88 later year model where it had the s5 idiot cluster and surround and i belive the guages and it has a 85 s4 cluster in it

royaltrex7

i wasn't listening trust me i have topped out my speedo with the 90 tranny and speedo drive in it

Icemark

Perhaps I amnot understanding your wording.

The 88 model year is a S4 car.

The 85 model year is a S3 car and a different body style

The gauge cluster and Clock/idiot light panels are two different things.

If you mean the clock/idiot light panel, and not the gauges, the 88 model year was the first model year to use the blacked out idiot lights and reverse angle trim, with a clock/idiot light surround that also had a lip on the top edge.

The S5 models used a simular clock/idiot light panel, and a identical trim panel and idiot light surround however the S5 clock/idiot light panel had different symbols/icons on tha ctual panel itself and different wiring.

royaltrex7

ok my understanding was somewhere around 8/87 manufacture date on the 88 model that they had done minor modification but had changed out the interior but keep the 6 port with the dynamic chamber and the 89 the true s5 had the vdi intake

Icemark

No. That would be wrong.

And all 7/87 through 12/88 are 88 model year.

All 88 model year non turbos used the same 6 port intake system (sans VDI system) as the rest of the S4 cars.

The only non cosmetic change was changed 1/87 as part of the 87.5 model change and that was the injector impedance.

And the only cosmetic change was the idiot light cluster went from seeing the idiot lights to a blacked out panel, with a lip of the surround.

The 88 models did not get the 89+ gauge surround, and radio surround or door panels.

thanks for correcting me i was talking to a man i know named kevin over at rotaryresurrection and he said your the man on all this so ill take your word for it and i saw the faq on how to wire up an s5 cluster in place of the s4 that would be nice to have a link in here to it i wont do it because thats yours you know?

Tokyo-RX7

link to write up? i wanna do it

note this is not my write up or my website all the credit is icemark's and of course kevin at rotaryresurrection for posting this in his faq section

chexmix78

Kevin swaped clusters, on my car, He asked Icemark how it was done, regarding the pins. which led to the writeup.

i feel special.

I also got the ball rolling on the 4 pc. pedal set. Once again I did no physical work, but because of me wonko the sane sent a cad design of the dead pedal, which led to the production of the 4 pc pedal set. so in my own way i contributed to the FC world.

yeah
