Hey all..

I've got a 94 EF auto, completely stock currently bar a 'dragon' performance filter in the airbox...

The engine has about 60,000km on it.

I'm thinking about doing a few performance mods such as
extractors, exhaust, cam, chip, and perhaps if i get adventurous
even some head work.

My question relates to the stock auto gearbox. I've just recently had it
rebuilt (after 150,000km). I've heard of nasty things happening to this box
if you put much more than stock power thru it. Is there much truth to it?
If I do keep this gearbox, one thing that I'll definetly do is put on an oil cooler.

One option I spose is throwing in a good manual box like a supra turbo 5
speed or something, but thats likely to be ultra expensive.

Cheers,
-Shaun

Put an oil cooler on it and it will easily handle 150-170rwkw. To be honest I'd doubt 200rwkw would worry it much either.
The Falcon 4 spd auto is a tough bugger, I doubt you'll worry it.

hey mate, ive got a 94 ef with 150rwkw and my auto is handling it fine no problems what so ever, but your right in getting a trans cooler, im having one put on in january as well as a shift kit maybe even a stall, but at the moment its runing smoother than ever just keep it serviced.

Casper

mine is handling 150rwkw at the moment and hasnt got a cooler (but I'd like to get one). They are a tough box.

some of the turbo boys are pushing big numbers (200kw+) through their BTR autos.. Its not power that kills them but the heat.. Go for the cooler and you'll be fine

Sounds great...

thanks for the info guys... at least thats one thing less to be worrying about...
Any other things I should be looking out for when pushing more power thru?


I doubt I'll ever get any more than 200rwkw... I'm not made of money :)

is the xr6/xr8 gearbox the same as the gli?

just don't do any stupid shifting like i did and it will hold out fine, i basicly thrashed mine cause i was young and dumb, and then i found i had some money so i bought a t5 :D

the auto to skip gears, go into limp mode or something make a heap of noise and had some trouble finding gears, kinda made it a bit more fun and intresting to drive cause it was like a high stall in 2nd gear but got annoying in the end

Thanks for everyone's input... Its renewed my intrest in moding my car..

I've just put in a cold air intake with some of that flexible pipe that is made of a rather heavy duty (what looks like) aluminium foil with a wire spiral thru it for strength. Just waiting for some silicone to dry and then i'll take it for a drive.. see what difference its made.

Next thing I'm thinking about is sticking a turbo on it. I'm gonna do some searching thru some old posts and see what I can find out. I'm sure google would also be useful. I'm in Perth... any recommended 'tuning shops' to goto to check out pricing etc?

A mate of mine (who is a fan of rice power) has said that reconditioned turbos would be a good place to start. I forget which turbo it was he mentioned, but aparantly a good recon turbo would start at about $1000.

I'm expecting a turbo setup to cost some where in the region of $4000 for turbo, exhaust+headers, inlet piping electronic boost controller... does that sound about right?

My other concern with adding a turbo would be the gas system on the car. Its an OMVL compex mixer with a gas ring. I noticed that there is a hose plumbed into the air box on the 'dirty' side of the filter. Obviously this is so the mixer can detect the vaccuum generated by the engine sucking the air in. Any ideas as to if this will still work with a turbo?

Anyone think I'm wasting my time even thinking about turbo'ing a dual fuel vehicle?

Cheers!

i think turbotrana is still suing his stock ed auto gearbox and that car's turbo'd and running 13 sec's

the 4spped btr is a bloody tough box if you keep it cool and put in an electronic shiftkit. The only problems it has is the selector switch and S5 solenoid.

I'd turbo my EF tomorrow if I could find a 5speed box that would handle 300kw and my driving stile for under 3k :)
