Rear Iron
what is the difference between a s4 and s5 rear iron? is there even a difference? i have a s5 and it recently cracked so im looking for another one. someone offered me one off a s4, thats why im asking.
|
im pretty sure there interchangable correct me if im wrong..but the s5 is stronger i believe
|
|
|
one more question. are s4 tII and s5 tII rear irons interchangeable?
|
I believe they are - but you want the S5 rear with both strengthening mods - probably off a 91 or later car - I broke my rear iron - probably down to twisting forces on a hard launch.
|
Check your e shaft too....I just noticed a small crack in mine lOl.
This was a 3'rd gear down shift and unsprung clutch....I'm not too quick to say it was detonation with those factors unless some thing happened unknowingly after two years of torture . s6's have it soo easy..... |
Well....I just cracked mine too! Must be something about Idaho?
Can you use a S6 iron? |
I took a bunch of measurements when I upgraded to s5 irons: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/just-measured-s5-turbo-rear-iron-factory-bracing-pics-795339/
I measured a 19% thicker dowel pin landing on the s5 I had, which came out of a 91 JDM engine I believe. Also, the secondary port runners are slightly bigger on the s5 irons, you can see it if you compare the s4 and s5 turbo LIM gaskets. I ended up swapping to all s5 irons and then used s5 JDM intake manifolds. Well....I just cracked mine too! Must be something about Idaho? Can you use a S6 iron? |

what ecu are you running?
Running 11.4 AFR Pulls like a SOB! Apex seals are fine. Don't think I detonated. It happened in the middle of 2nd gear and pulled hard all the way thru 3rd. Didn't die when I came to stop like a blown engine does. I thought my car was on fire! Grabbed the fire extinguisher and opened the hood. Engine was coated with oil! |
