more tuning options, cos i had some time on my hands at work so got on the phone the first set are from courtney on 01692 404060 and none include fitting: mansell 256 degree cams 14hp £490 headwork 10hp £560 lightened flywheel(3kg less than std) £175-(quite tempted with this) they did a back box, remap etc as well, and are based in norfolk, but haven't tried them the second is a place called blydenstein engineering who does a lot of vxhall head work and seemed very knowledgeable, though he hadn't touched a 2.2ecotec before, and he would only want a stripped and clean head etc sending up stage 1 is work on induction ports and inlet valves, costing £295+vat and giving about an 8% increase in horse and 6% ft/lbs stage 2 would include the exhaust side as well, costs £445+vat, but he said the returns here would be minimal e.g. if you got 10hp from a stage 2, only about 2 hp would be from the exaust-so he advised me that it wasn't really worth it, but pay your money take your choice cheers d p.s i have had all my work done at regal and it's been superb, also alot closer for me.

mansell 256 degree cams 14hp £490
headwork 10hp £560
lightened flywheel(3kg less than std) £175-(quite tempted with this)

Hmmmm. Interesting. Mr Courtenay's son currently works for me...... I'll have to see if I can get a discount....(although he's in Germany at the moment....)

i think the guy i spoke to was called john, and was very helpful. cheers d

it s going to be expensive on the labour side of these mods......i am thinking that if i/we are going to mod the head and cams then this should be done together to save on labour costs...what do you think? my friends at regal have a 2.2 ecotec engine to play....they are going to be testing timings for taking it apart for mods and also they are going to look at the cams and head to see what real extra can be got out of it!! for me i am hoping that a change of head and cams will push may car to at least 210bhp/190lbft ( if it gets to 220 i will be very happy!!!)

mmmmm.....been asking around myself......
cams 256deg. are 815 euros+ shipping at dbilas, CLAIMED 10-12 hp (depends a lot on the following remap....)

porting and polishing heads...cool stuff, not very cost effective considering the limited power gain....labor is a killer there, the whole engine is taken apart.....

cams are marginally easier to install labour-wise....but then a remapp is needed....

when entering those areas you really need to ask yourself WHY and IF you want more power....too much could become a limitation on track, since you would spend most of the fun concentrating on reining in all those bhp's.....

also, the power may shift toward the upper end, limiting low-end torque... like the 256 cams will do somewhat....
how often will you rev up to 6800 rpm to get those +10 hp?

that is why I am going to assess my car with the new exhaust+intake/OZ/yokos/spax combo.....
I will drive to the Ring for the 18-21 April "long" weekend;
after that, IF I were to discover that my speedy is still underpowered for my skills, I will go ahead and work on cams......but I doubt......

Of course!

With a car named VX220, you have to go for 220bhp!

But then any self-respecting VX220 turbo will have to have considerably more. How much can it reliaby deliver? 250? 260?

Ricky is right that it's great fun as a lightweight, but those Porsche turbos do leave you for dead on the straights. Would be nice to give them an even bigger fright.

[ddpunter]

could 'just' go for 220bhp/ton anyway, back to ricky, I seem to hit 6600 most days, and isn't it nice to suprise people who assume your car has only so much power? And even though these cars hurtle through the bends, the extra push is great when the straight opens up. Minime-let me know if it will be cheaper to get a few cars done at once, although cams and headwork is probably where I would stop. By the way my bro rebuilt a gtir engine to produce a reliable 330brake and was self taught-he says it's not too bad to do if a bit nerve wracking on startup, so the selfstrip/build is perhaps not out of the question... cheers all d
