Turns out I can mix and match the individual gears from the short and wide ratio's.
Thinking I will do all-short, but a wide 5th. This will give me most speed-in-gear for all gears.

I've been told (anecdotally) that the Quaife gearsets aren't really that much stronger than the stock ones, and that they fail too. No personal experience (I still have an ailing 5-speed in my car), but I'd sure hate to spend three or four grand on a sexy Quaife transmission only to have it blow up just like a 5-speed.

Well, I can tell you from experience that they don't. I'm putting 350+ lb-ft through mine and, after a judicious warm-up cycle, I don't exactly baby it.

Now you have two anecdotes to draw from, each with differing conclusions. I would, however, hazard that a stock 5-speed would have left me walking a long time ago.

Lookin fresh! What ratios did you end up going with? The close ratio with wide 5th? I've got the close but my car's not running yet but I'm anxious to see how it feels to go 60 mph in 1st gear.....lol. I just hope it's not a pain to launch but I'm sure it wont be the funnest thing.

60mph in 1st? No, 50+ yes.

+1. While I'm not @ that power level, my gear set is still functioning like it did new.

2/3 cobra and Deer Hunter, do you guys both have the wide set? I was looking for some input from the close set as to first gear and how street able it is. I know it will vary with power levels, clutch, and flywheels combos but if either of you have it I'm curious to know if you dont mind.

I have the wide set, coupled with a 4.10 R&P, stock flywheel and FM Level 2 clutch. I have no issues starting, but I do benefit from the added torque from the stroker motor.

After looking at some different combo's I think I'vew realized the point of the "close: ratio gear set. While the wide set is setup similarly to a traditional 5 speed the close gets shorter and shorter and the gears go up. Typically, as a car goes faster there is more air resistance and in tern, accelerates slower. I think the close set is designed to compensate for the increase in air resistance so it pulls just as hard at 100 as it does at 40. Am I crazy here by this hypotheses?

Yes, all short but wide 5th. I have a 4.1 so I forgot that a 3.6 will do 60 in 1st

Just make sure you have the correct box to drop the set into. Although Quaife say any 5 speed box it was actually blue printed on a 1994-97 box and wont fit anything else as the 2nd gear synchro's are different. I have two trannys in bits as a result of this.

So if you don't know the providence then remove the front input shaft bearing cover and you should see a circlip = right box. Another point is the long bottom case bolts which pass through the carrier (which needs machining to take the bigger 1st gear) have a habit of shearing in use, case flex? Consider drilling out and replacing with high tensile nut and bolts as they are a pig to sort with the tranny in the car.

I've got a 2000 box, so what needs to happen to make it fit?

Nothing. Sell it, it won't fit, get the correct box with the correct 2nd synchro.

Pull up the schematics, but from memory the 2nd synchro hubs change from being integral with the 2nd gear up to 1994 then separate and then integral after 97 or it might be the other way around its being a while since I did the swap.

lol....I have my Quaife set in a 2000 box. I bought it like that so if what the guy above is true I'm not sure how it's in there.

Thanks, I needed a heads up. I'll leave it to the geartech guy who is putting it together to tell me if it was possible or not.

I also have the wide set. The wide set was my original recommendation when I provided the trans and specs to Quaife. The ratios are based on the 4.1 R&P. This included veh. weight, OE clutch surface area, wheel/tire circumference and HP/torque values off idle on a 100 whp Miata. No issues with drivability at all.

If you want to split hairs, the set was fitted to a 95 box. The case bolts should be replaced and torqued to spec during the install.

Wait, you're saying the setup you have was designed for a 100 hp(stock miata) and you're running it with how much power? and it has no issues?(loss of traction, running out of gear too quick, whatever) You must be under 300 whp?
