well folks, what would be the best cams to get for the 6 without having to do any work on the pistons so the'll have clearance and what would be the rough expected gains along with an induction kit and decat which i already have? also would it have to be remapped with milder cams as nowhere in this sh*thole of a country will remap the standard ecu Angry

I'm running Kent PT81's. Opinions seem divided about the inherent risks of these without pocketed pistons, especially your head has been skimmed etc,(do a search - loads of info on this) but i've had them in for about a year without problems.

As for remapping, Wayne Schofield of Chipwizards can remap the standard ECU (he did mine). I have standard induction, and made 184bhp

was your head ever skimmed do you know? 184 is good with cams alone Smile is there much improvment power wise when your driving it?

yes, my head has been skimmed, but my valve seats were recut too so i think i regained a little clearance with that.

Yes the power is good. it comes on pretty strong around 4k as it always did, but then the cams really come to life at 5k+ (vtec-esq almost)
I dont suppose its anything like as hard hitting as say your supercharged boys, but it updates the car nicely.

I will be putting my newman ph2 cams in this week, so will let you know, i will also be booking a remap with chip wizards as he seems to have had the most experience. i think these cams are very similar to pt81's

my head had been skimmed too just a light skim when i was getting the valves done but still would be a bit warey, is there any way of checking the clearence without taking off the head, mabey by taking off the inlet mani as i remember i could see the valves in through this when it was off Dunno

what sort of gain should be expected from pt81s or simalar cams. im running 178bhp and my engine is standard.
it does not seem worth nearly a grand for only 6bhp.

How much torque are you lot with cams getting then? BHp doesn't really mean a great deal if the torque isn't increasing significantly as well imo.

is there any cams that can actually be used if the head has been skimmed without piston work?

I'm sure the kent PT80 or Newman phase1 would meet that criteria, but you'd have to ask yourself if its worth it for such small gains. I guess it depends what your goal is - to make the car faster or quicker? That may sound like a stupid thing to say, but bare in mind you can make a car much quicker on road or track by changing suspension/reducing weight/buying decent tyres....without it generating more power

PeterT stage I inlet cam should fit with no drama, he regrinds the standard cam to give longer duration but lift stays the same, so as long as the timing isn't way off it should cause no drama.

As for mapping i'm going to be a sheep and use Wayne too, despite my earlier kicking and screaming LOL

That's the route i'm going down. Emailing him as we speak and I have a spare inlet cam on order to ship over to him. I'll let you know prices when it's all arranged.

well at least with these id be safer anyway yes?
how much roughly would kent pt80/newman ph 1/petertstage 1 cams cost and would there be a best one out of the 3 or all fairly even? and would you have an idea of the rough bhp/lb/ft gains with them?

ive been considering a piper fast road regrind, send them your cams (or a spare set) and for £250 they will grind them to fast road spec.

http://www.pipercams.co.uk/pipercams/www/product.php?pid=GTI6BP270H

And he did say that if 5 or more people wanted some they would talk about a **GROUP BUY** discount.

PeterT's is probably the cheapest of the lot, a regrind is about $150AUS. Add on £70 for shipping (£35 each way) and about £20 for a spare cam and you can get it back on your doorstep for about £170.

Don't quote me on this but with the mods i have i'm hoping for 10-15bhp after a remap, hopefully get me up near the 190bhp mark.
