I understand what your saying too matt. I a few years ago had problems tuning a FWD Nissan. It chew up and spat out new engine mounts every 3 month's. This was annoying coz putting the foot down meant the engine hit the firewall....

These mount were $200each, and I was sick of paying $800 a month for a weak design. This was actually really rough to drive because the dynamics were all out, the motor basically was free in the engine bay, bounced around after the car, and upset the handling and knocked around

If your engine mounts start to go, which I hope they don't, it does little for handling or responsiveness. Once they deteriorate they don't last long till theirs

I bought the Urethane through pedders, But that was about 3 years ago. To date the engine mounts haven't failed..... But it's driven a lot more gently now. Have a fair bit left over, but it's not cheap I think I payed $300 for 1 block, but enough to do the car 3 times

Cripes!! that sort of issue calls for a drastic solution...like strapping the mounts to limit their movement..short lengths of chain can be used :D

Hey Josh, I think you need to port and polish the head, fit new pistons, put the AWD box in and you may aswell respray the car while you are at it :lol: :lol: :lol:

OH I forgot ! don't forget to do the trim.

Dan :lol:

where will it end

^^^^ Now that would be sweet, but don't u think this thread is getting long enough already. He'll need his own room in the forum. :P

Seriously, just had a good look through whats been done and it looks as though your doing an awesome job on the car. Especially love those wheels!

Good luck with the rest of the build, look forward to seeing the finished product. 8)

One thing at a time :P :lol: :mrgreen:

AWD maybe one day...

I wish i had a pool as well though...and a house...haha

for now i have to setlle for my new Quaife diff :)

Quote:
The characteristics of the differential are that it progressively locks as torque increases; there are no plates or clutches to wear out, as the more conventional limited-slip designs incorporate. The ATB differential is particularly effective in combating the effects of FWD torque steer and understeer.

Shuuuuuuut up. :P At least i'm not wasting the cost of a car on a ring :roll: :lol:

I've got the turbo off getting modified by John at Precision Turbochargers in Wetheril Park, he's putting a new 12psi actuator on so that i can get it to boost up where i want it 8)

With comments like that you should have done the conversion on a van rather than a sedan so you have somewhere to sleep when you're in the doghouse for not spending the money on a ring .

Neither :P


I got my Engine Mounts back yesterday and i'll put some pics up on the weekend.

Just waiting on my Diff which they say will be here be the end of next week :)

Thought i'd post up some of the key reasons i went with the Quaife over the TRD One..

Why not use a traditional, plate style limited-slip differential?

Method one is to use a traditional, plate style limited slip differential, the type of which is used commonly in racing and rallying. This uses a pack of clutch plates worked by sun and planetary gears to transmit a set percentage of the torque to the spinning wheel (say between 40 and 50%.) Certainly these units are effective in increasing traction, but they do have negative implications on both driver enjoyment and vehicle longevity. In some applications on very high performance cars the LSD's clutch plates are now engaged using computer-controlled electro-hydrualic action, with obvious cost implications.



i) Potentially negative dynamic effects

Unless it's set up correctly, a plate-style LSD can ‘snatch' as it suddenly locks to maximum torque transfer. This is particularly noticeable in a front wheel drive car, usually when driven rapidly along a bumpy road, as the vehicle will tend to skip from bump to bump as the LSD tries to transfer the torque to the unloaded wheel. A similar effect will be experienced in a powerful rear wheel car, albeit not felt directly through the steering, but nonetheless this can compromise driver enjoyment.



ii) Long term maintenance implications

The traditional style LSD's reliance on clutch plates, as well as sun and planetary gears for operation ultimately leads to wear on these components when used hard. For example, it's not uncommon for high performance track / rally cars to undertake a differential rebuild at least once a season.



d) The Quaife Engineering Automatic Torque Biasing differential

The second mechanical method of improving traction is to use a Quaife Automatic Torque biasing differential. Rather than using clutch plates as a method of operation, the Quaife ATB uses sets of floating helical cut gear pinions that run in pockets and mesh during normal driving.

Should one of the driven wheels start to spin however, the helical gears start to generate a torque bias thanks to the axial and radial thrust of the helical gear pinions in their pockets. The result is a progressive transfer of torque away from the spinning side of the axle to the driven wheel, which is now capable of transmitting a greater proportion of torque.



i) Positive dynamic effects

Because the Quaife ATB differential's design produces a progressive transfer of torque away from the spinning wheel to the wheel that's capable of driving, the effect is far more benign to the driver. In a front wheel drive car harsh snatching and torque steer are eliminated, so much so that it's not uncommon for a Quaife ATB differential to cope with 400bhp through the front wheels in aftermarket road applications.

For rear wheel drive use the benefits of the Quaife ATB diff are obvious - excellent tractive qualities, combined with a progressive action, making for a benign, effective and involving package for those seeking the ultimate in safe high performance vehicle dynamics.


ii) Maintenance free performance

That's right, unlike a plate style LSD the Quaife unit delivers its performance without the need for stripdowns and rebuilds. There are no plates or gears to wear or break and the ATB units retain standard vehicle lubrication.

Sounds great!

However I've read that they become is useless if a wheel ocmes completely of of the ground. So keep your front wheels on the ground! :wink:
