Hi all,

Is there anyway to identify standard camshafts on a 2wd Yb other than taking them out and measuring them?
Not sure if mine have been changed or not! (3door)


Thanks for any-all info.

Aftermarket one's will usually have their ID stamped on the end of the cam (opposite end to the cam pulley) such as BD16.

Thanks rich, will have a look tomorrow. In your opinion what if any difference does a cam change above standard have on lower end torque/power.

Cheers, T.

Anyone have any thoughts about cam change above standard-re power-torque?

It all depends on the spec of the rest of your engine, you need cams to suit.

All standard, apart from valve springs, well I suppose not really that standard nornal stuff 0044 fuel pump-071 plugs-atb diff-7.8 cr - looms up-rated-drive-shafts-train uprateed. the usual 500 intercooler/rad/turbo cooler- along with group a coil.

t34 turbo (but not as most know it im told )

Inducer comp- Major-3 inch
Minor-2.122

Turbine
major -2.555
minor- 2.126

Getting 7psi @3000 rpm everyone else seem to achieve more? but I wonder if this is down to the fact that a T34 exducer is 69mm where mine is 76mm?
Looking at all posibilities, as I don't think a journal bearing turbo is that far behind a ball bearing item of the same stock.


The forum goes dead when knowlegde is limited !

I wouldn't change the exhaust cam i'm running 550bhp and i'm still on a standard exhaust cam.
Has the head had any port work?
It may benefit from a sliightly larger inlet cam.
