I reckon it comes down to the gearbox...i mean if it's itr, and therefore have an lsd, there's no way the guy:
1. blew his engine
2. bought a jdm integra type r transmission (cos i know my ratio is 4.4 final drive)
3. bought a jdm SIR-G block
4. bought a jdm/audm integra type r/civic head
and threw it all together. it's too much effort for too much stupidity.

Or maybe he blew his engine and got a JDM B18C from a type R as a replacement and everything else is still the same. I wouldn't rely too much on a gear ratio calculator to tell you whether you have a 4.4 or 4.7 final drive. Unless you have someone with a DC2R with known 4.4 final drive telling you that your engine should be spinning at xxxx RPM at a certain speed, I would still be guessing that your gearbox could have a 4.7 final drive.

A gearbox doesn't really mean shit, a gearbox can be replaced if the guy is a total nub and blows it..

So lets get this straight

- you have a 4.4FD
- you have B18c stamp with no number after it (on the top line)
- it revs to 8600 (approx) like a type-r engine

To me it sounds like you might have a complete '96 Spec JDM Integra Type R engine+gearbox package. Possibly the original engine blew and the owner could only locate a full gearbox+engine package or a halfcut and thus they swapped the whole lot in.

Thats my thinking anyway.....

But like aaronng said, how can you be sure you have a 4.4FD?

yeah, that's what it sounds like.

i'd be pretty happy if i got a 96 spec halfcut in my AUDM ITR.

sounds like a win-win

^ everything above is correct and what i think.

i think it's a 4.4 fd because:
i found the gear ratios for the integra type r 96 spec, sir-g and itr 98 spec engine.
put them into a calculator
went out for a drive
and found that at 100km/h in 5th i am doing ~2800 rpm, and the calculator for the 96 spec itr transmission gives me 2880 rpm....

awesome dude looks like u didnt get stiffed! :cool:

LOL.... you thought that you got cheated but in fact you got the good deal...

Which calculator did you use? The mfactory gear calculator reports ~3233rpm @ 100kph for a 96 ITR transmission.

2800rpm is too low for an ITR @ 100kph. Assuming a 23.4inch tyre height, 4.4 FD, 0.848 5th gear, 100kph = 3324rpm. A 0.878 5th gear from a VTiR/GSR gives 3084rpm. A non-vtec S80 gives 2700rpm with the longer FD and 5th.

My non-vtec B18A does 110 at just under 3300rpm indicated => calculator (excel) reports ~3200. This is a higher rpm per unit speed than your "ITR" transmission. Suffice to say I there's something fishy going on.

I don't think you're in the clear just yet.

Told you got an ITR jap spec engine :)

hmm, i used the mfactory one and i've got an sir-g transmission still don't know about engine block and internals are definately integra type r (cams n pistons and stuff).
