4.3s going in tomorrow and I really cant wait to see how it goes after its done. Is it really that good a mod on these Cobra's like everyone says?
Wooo Hooo 4.3s going in tomorrow.
- Thread starter XR8XTC
- Start date
Ive heard that it is. My brother has a '96 that he's planning 4.10's for so keep us posted on the results 
Yes.
I should know tomorrow. I hope they dont make normal driving a pain in the ass.
i had mine put in a few weeks ago, love every second of it! But also had to get drag radials
One of the best mod you can do to a N/A DOHC...
I've had mine for about 9 months now and believe that this is how they should have come from the factory.
Don't be surprised if you have driveline vibes at high speed with steep gears. My car needed an aluminum shaft to cure it.

4:30's are the way to go n/a. Have fun:burnout:
Sounds all good then. I was just worried as never done this on a manual before. Did 3.73 on my Auto Z28 LS1 and was happy with it. I just bought FRPP Aluminium D/Shaft for $299.00 will fit that soon. Should I fit D/Shaft before or after Dyno Tune?
BTW All this is being done here in New Zealand. I know Sig says Japan but I live in both.

Ok picked her up and just got back from 400km long slow drive to wear them in. Feels interesting and cant wait to start blasting it haha. Two bad points so far are that at about the 300km mark of the drive the check engine light came on and a viberation felt when stationary in neutral gear.
Anyone know if the Aluminium D/Shaft will fix this vibration?

aluminum driveshaft will likey correct the vibration
stationary vibration? cant be the driveshaft as it doesnt move when stationary. might be worth picking up a cheap obdII reader then checking out the code.
Its going to get Dyno tuned monday so I will get engine light fixed then. What would cause statioanary vibe you think?:shrug:
misfire of some description? maybe caused by some old plug wires? idle air control valve? does the engine light flash or stay on full? if it flashes it shows a misfire. its hard to say for definate without pulling the codes.
It would be advisable to address the problem before putting your car on any dyno.
Stays on and no misfires. I will check codes and get it repaired before Dyno tune for sure.
