Anybody done this and able to comment on their high-speed driveability (cruising specifically)?
Internet calculators suggest my 0.870 5th + 4.9FD = 4,000rpm @ 100km/hour.
Wondering if its worth considering sourcing a B18A 5th gear which is 0.717 and supposedly equates to 3,300rpm.
So, any personal experiences?
This isn't a daily driver and highway miles would be scarce but I don't want to rule out the possibility of jumping on the eastern freeway or doing a rural road trip...
my old 20v blacktop corolla sat at 3800 at 100km.
it was fcking horrible.
im willing to know as well...
I'm assuming its terrible but just want some anecdotal feedback.
Probably just going to grab myself a B18A cable 5th gear anyway
I have one in mine. B16a2 box with osgiken 4.9 final drive and mfactory lsd.
It sits at 4000 rpm @ 100kph but its not my daily so I dont care. I've done various 1h+ trips without worrys. The acceleration is fantastic though!
whats your tire profiles n8s

mocchi I'm running 195/50/15 and another setup 185/60/15
that really depends on what exhaust youre running ayQuote:

It'll definitely drive you mad eventually in a daily, but for a weekender a 4.9's the ****.

It's fine for me, I don't even have a stereo either. You're only under very light load so there isn't much exhaust noise. The extra workload was just a compromise I had to live with going to it. The performance gains outweigh the downfalls for my occasional highway driving.
Setup is JDM B16A. CAI, Rs*R header, high flow cat, Kakimoto R full cat-back, ITR TB + IM, Skunk2 Pro1 camshafts and adjustable gears, Jun oversized valves, Supertech titanium retainers and HD valve springs, enlarged intake/exhaust ports, matched manifolds and re-welded combustion chambers (smaller for higher comp/more flow).
Exhaust isn't too bad, it's a nice oval muffler, typical JDM piece good deep/throaty sound and high-pitched screaming up to 9,000rpm.
And yeah, just a hobby/weekender so I don't foresee much highway driving but I don't want to hate it too much if I drive down to say Apolo Bay and get some 110km/hour highway action.
4.9FD is ordered an definitely going in, just wondering if I should consider lengthening the 5th gear to bring the rpm down a bit at cruising speeds as I don't predict much need for 5th acceleration. By my rough calculations the longer 5th + 4.9FD should pretty much be similar to my oem setup of shorter 5th + 4.26FD.
Nice information on 4.9 Fd
I know brett off crx aus has b18a 5th gear in his ef8 worth ask him what he thoughts on the 5th gear
