Metal salad in my 5-speed, MLV and sound.

So, driving around tuning fuel, gearbox goes boom.


For now I am dropping in a replacement 5-speed. Is there any difference in the early 1.6, early 1.8 of later 1.8 gearboxes?

Wasn't expecting it to blow this soon...

ouch..

No, and apparently there's no difference between the 5spds and a 6spd either, just an extra gear. You need to convert to an OEM transmission engineered and spec'd for the kind of torque you're putting down.

18psi 06-03-2010 02:20 PM

god damn it....and here I'm aiming for mid 300's very soon:facepalm:


regarding 6 speeds: I'm pretty sure they are capable of holding a bit more than the 5 sp, simply due to the fact that the gears are shorter and closer, as well as having a more rigid bellhousing allowing for less flex, and less torque load going from gear to gear. just my uneducated guess.

Laur3ns 06-03-2010 02:28 PM

I was in 3rd or 4th, can't remember actually.

Who is running the Quaife gearset? The wide ratio w/my 4.1 Torsen is tempting. But only if it will never break.

18psi 06-03-2010 02:29 PM

try it and see:D

Laur3ns 06-03-2010 02:37 PM

Would you pay more to get a 15.000mi NB 5spd over any old 100.000m NA box?

Yes, NB 5 speeds shift soooo much smoother than NA 5 speeds.

What's the write-up for this R&R?
- Drain gearbox
- Remove speedo cable and wiring clips
- Unbolt PPF and move it to the side
- Unbolt drive shaft and move aside
- Tilt engine slightly backwards
- Unbolt range of 14 and 17mm bolts, including starter
- Remove?

Missing something?

fooger03 06-03-2010 03:17 PM

Big exhaust? Unbolt downpipe and remove.

My 6-spd wont come out with the 3" downpipe in place.

Just lifting the car off the ground ;)

18psi 06-03-2010 03:27 PM

taking it out is cake. aligning the input shaft when putting it back on is a bitch.

Laur3ns 06-03-2010 03:27 PM

- Lift car up HIGH
- Remove shifter as a whole
- Remove cat back
- Drain gearbox
- Remove speedo cable and wiring clips
- Unbolt PPF and move it to the side
- Unbolt drive shaft and move aside
- Tilt engine slightly backwards
- Unbolt range of 14 and 17mm bolts, including starter
- Remove?

18psi 06-03-2010 03:28 PM

disconnect shifter

Cue Huster's millionth anti Quaife tirade.

http://www.toysport.com/catalog/PET%...Conversion.htm

buy Bell Housing from there "S-RWD W or T bellhousing"

buy W58 supra tranny

buy 3SGTE adapter plate from me

enlarge your tunnel, make some mounts and a custom driveshaft

profit?

Quaife sucks because I bought a $900 differential from them, had a pro install it for $500...then one of the first times I ran the car on the freeway in 4th gear at 480whp the diff's case broke. I called quaife and those ******s told me they would only warranty the internal gears, not the case and they'd sell me another one at a reduced priced.

I told them to eat my shit on toast and Gary Peloquin chimed in and cut me a deal on his differentaial that was fine in my car and my friend's 900whp car. I wish he'd made differentials for us...time for me to call.

It will be a cold day in hell before I give Quaife a god damn red cent.

Peloquin > Quaife. I have never heard one bad thing about Peloquin and they are cheaper with a better warranty!

Peloquin offers a "no questions asked" warranty and apparently no one has ever broken one. I want him to make diffs for us but not sure if the planetary diff works as well as a clutch diff.

chicksdigmiatas 06-03-2010 08:55 PM

Toasted gearboxes are never fun. My secondary shaft broke in half on my first kill.

The 5 and 6 speeds fit up pretty much the same, they both have gears in them but they are significantly different inside and out. Independently Designed and manufacured by different suppliers nearly 20 years apart from each other.

I don’t know for sure why but the 6 speed in my mind is proven to be stronger. I have broken seven 5 speeds with 3 different failure modes trying to put more than 350 hp through them. The 6 speed has lasted 10 times longer so far.

Oh, and there is actually 3 differences in the 5 speeds but none of the changes really effects strengh or function much. they upgraded a syncro once in the series and later changed the shift turrnet on the 5 speeds over the years.

Put my name on a 2000 NB 5-speed box with 15.000mi.

Laur3ns 06-04-2010 04:44 PM

So, the old gear salad bowl is out. I'd better remove the downpipe too when I get the new box in. Took about 3 hours working on my own. Not too bad. The fact that the car has been apart before helps.

I can't see how I would get a new box in by myself and as I've lots of other (real) work to do, I'm going to have it done.

chicksdigmiatas 06-04-2010 05:36 PM

Its not to bad, paying a buddy in beer to help you wiggle the input shaft back in would be a wise investment.

Pay for my plane ticket and I will do it for you. I have to swap :brain: trans tomorrow. I think we are shooting for 1.5 hours total time.

If you're doing it yourself seriously consider using rope through the shifter area to keep the tail end of the trans up so all you have to do is handle the bellhousing area. Always makes putting it back in worlds easier for me.

Actually, after they told me that I spent $900 on their diff, $500 on install, and they offered a "deal" at $700 plus shipping, I told them to eat my shit. I yapped on the phone, so I won obviously.
