Jerico Gearboxes

[Simon-S14]

for what i want to do it would be ok tho yeah?

[urtwhistle]

oh k cheers for the heads up with the price. Yeah my car is turning into less of a street car every day.

[Risking]

For a mild rwd engine they will be fine. They don't have a massive torque threshold like others but that's mainly due to the compact size.

As a guide the nz touring cars have around 450hp and 600-700nm from memory.

The boxes are very reliable behind those engines.

The Dubai guys do break them with the sequential shifters but watch some YouTube in car footage and you'll quickly see why they break them. It's no wonder Mal rose wiped the floor clean when he did a round over there.....

[Simon-S14]

the box i was looking at comes with Emco gears and can handle significantly more torque then the jerico gearset.

ive watched a few incars of the dubai guys... what is the cause of their failures??

[Risking]

They use the renegade shifters and no ignition cut. They have to lift on gear changes which alot of the time doesn't happen fast enough or long enough. Resulting in broken selectors, engagement rings and the odd gearset

I'm sure 8k is retail for a ppg box if you were sponsored you wouldn't pay that

why not just get a Japanese gear set second hand off yahoo

only be like 2k if that and you wont have to swap lots of junk

[Simon-S14]

yeah i dont think so.. a "jap" gearset is still not flawless...

[sheldonmcg14]

So has anybody actually fitted a Jerico 4 to an rb?

[Risking]

I haven't done the conversion from scratch but I've fixed a car that had a bodgy job done of the conversion.

We had to trial a couple of diff ratios to get a decent spread.

Works okay now the clutch and flywheel issues are sorted.

[Simon-S14]

ended up buying one.. being shipped now. Got a bellhousing lined up and we're going to attempt to make our own sequential shifter for it.

[9krpm]

how heavy are these compare to the rb25 or rb25 with ppg gearbox?

[Simon-S14]

35kgs + extra for bellhousing

[NYTSKY]

Keen on the results. Looking at boxes now and this might be an option.

[Simon-S14]

bit of an update... progress is slow.

Got a bellhousing from dellow.. its the first one they have done for this combo and im not sure if its entirly right.. but never the less some pics if you guys are interested

[NYTSKY]

So it is bolted to the Jerico by 4 bolts? Have some more pictures?

[Simon-S14]

yeah i have more pics.. will put up soon.

the centre bearing support/shaft diameter takes the load of the box and the 4 bolts hold it on.. much like a wheel on a car. the centre is like a massive dowel pretty much

[Simon-S14]

ok got it all in and up and running... was a bit of a headache but well worth it.

parts needed

3/4 bore master

quarter master hydraulic release bearing with custom made bearing extension to sit the bearing closer to the clutch

bellhousing

gearbox

custom tailshaft (i modified the front section of the stock s14 shaft, length is almost the same) yoke is Turbo 400 32 spline output shaft.. its huge!

custom gearbox crossmember

clutch (i used NPC rb clutch but with the spline changed to Chev 26 spline input shaft)

custom spigot bearing ( machined one up to suit the auto spigot area in the crank and protrudes out

[NYTSKY]

Good stuff.

Not exactly a bolt in option compared to a gear set swap so would the difference in outlay be worth going through the process you just did VS buying a upgraded gear set?

[Simon-S14]

I'm still well ahead of what a ppg would have cost
