My 2002 WRX has 17 x 7 factory alloys. Yours will be similar. From under the car, look on the inside of the spokes until you find "MADE IN JAPAN, 17 X 7JJ 55". The "55" is the offset. Which means the hub face is 55mm AWAY from the centre of the rim width towards the outside of the wheel. A "0", (Zer...

Idle air control is stuck closed.

Ok, cool thanks Gary. Knowing this, what would you set the timing to? According to what Paul says, my valve/ tappat clearance is 0.015" set hot? Cheers Cam Cam, I'd set the cam timing using the factory marks since the cam grinder has ground the cam to allow for a straight-forward installation. .015...

Breakdown not brake down.

Power steering racks are not for novices.

It's a baby cam. The advertised timing although specified at .006 and not .000 like the factory cams would be, is fairly mild. 210 and 213 degrees @ .050 also says mild, I'd call it stage 1. Bit disappointing that Camtech doesn't give you all the info on the card. No valve opening/closing event poin...

Just got back after spending $120, saved $30.

I bought a Datsun 1200 ute 8 years ago, good looking little truck, drove it 3 days, then pulled it apart to nothing. Has been a rolling shell ever since, I've fitted brand new 16 wheels and tyres, I've heavily modified the A series engine (Oval port Big valve head,H beam rods, forged pistons, roller...

The Frog and Brat share the same chassis. I had a Frog in the early '80s, I also have a Brat body conversion kit. Beware that being only rear wheel drive, they are prone to rear diff planetary gear stripping/failure. If you can handle skipping rear wheels on turning, I would make the rear diff a per...

We don't know for sure but from our experience doing the timing we believe the engine builder may have done this. But he is an absolute expert.

Cheers Cam

Yes, please do, I'm keen to look at it.

Brumby Kid wrote:What about if your cam has had a torquey grind and has been advanced a tooth or so?
Use the same specs?

I'd use the minimum clearance as specified by the cam grinder.

"Advanced a tooth or so" is way too much and should be setup with an offset keyway, degree wheel and a dial indicator etc.

My '02 WRX had that noise for a short while until I broke the transmission one night.
Too much torque at 5000 rpm in 2nd gear.

The Gregorys specs are way too loose, especially on the exhaust.

I set mine at 0.15 inlet (.006 ), 0.20 (.008 ) exhaust cold.

Beware about the "incorrect" clearance measurement you'll get while measuring between a worn rocker arm pad and the valve stem.

Any engine with valve seat inserts which includes ALL alloy heads are capable of running unleaded.

Steptoe has had his cam ground 16/56 and liked it (seems like a pretty popular profile) so I will be asking for that. What's popular might not be 'best' but I'm thinking there would be a reason it's popular. And if it isn't giving the desired results, there's the large knowledge base to draw from t...

Tony Knight at Knight Engines (Adelaide) Steve at Rusing sun (Adelaide) Do NOT get a 16/56 cam. Here's why. I would prefer to see you go to an engine shop who knows what they are doing and for ten to suggest a place to get your work done. Then they will collaborate on what is the best grind for you...

You're better off with a carbide burr in a die grinder.
A Dremel with a sanding drum will be ok for finishing.
Your heads do have a lot of overhang in the inlet ports.

The most important part of any port is the valve seat area and either side of it, including the valve head.

Cuts out slowly would be fuel pump, or pump relay etc.

Dead cut, like turning off the key, could be anything.

Which way does it cut out? Fast or slow?

Right right - good to know! So if the two more 'off road tyres' were the same specifications but had more rubber on them - being newer and more chunky they would be unsuitable? My rule is for any 4WD or AWD is to run the same brand of tyre front and rear, all 4 tyres of the same tread depth. Buy 4 ...

If one wheel is off the ground while in 4WD, the lack of centre diff still allows drive to the other 3 wheels.

Have a think about it.

Don't run different tyres (make or size) front and rear. Gearbox will windup in 4WD.

Does it say 95RON on the inside of the fuel filler door. The higher the octane, the more power the engine will produce because the ECU can increase the ignition timing thanks to the increased knock resistance of the fuel. I just fill my 2.5L Outback with 91 E10 at my local servo because although I ...
