Before anyone says search,read and learn I have but I'm still confused as to which way to jump or even if I should simply stay still.

Anyway a bit of background;

The car is mainly street with some track days, so some degree of drivabilty ie a steady idle without the need to rev the **** end out of it to see any gains is important plus it's keeper while I'm around!

Building a built 1.6 motor based around my current full FMII system with Adaptronic ECU with the following parts;

Bottom end; FM low comp pistons, H beam Carillo rods, ARP cap/studs, boundary oil pump, ATI damper, cometic head gasket, lightened 1.8 fly wheel.

Head: CNC 1990-2000 head/solid lifters, new valve guides with FM +1mm intake and exhaust valves, uprated FM springs and collets, port matched inlet and exhaust manifolds, ceramic coating to exhaust manifold, turbo housing and down pipe, FM fuel rail with current 550cc injectors, coolant reroute, thermal inlet isolation gasket, gates belts.

Cooling PWR rad and PASCET fan, clutch to be uprated, Quaife box, LSD all installed etc.

Question is, should I stick with the stock cams or as some suggest replace with the inlet cam from the 1.6 auto or go aftermarket for both?

If so can this be done with an "off the shelf" item(s) without any additional machining to the head which has already cost a fortune. There is very little this side of the pond without going custom which is silly money.

US supplier details, expected gains advantages/disadvantages info would be appreciated or should I simply leave stock?

Planning on using a cam angle sensor placed in the front of the cam cover so adjustable timing sprockets not really an option.

PS I'm no expert when it comes valve timing theory hence the question.

Thanks all.

I had two custom cams made for my 1.6L for $400.

Go take your cams in to a local grinder and tell them what you want for specs and they will find a profile that they have in their stock that will work with your cams and the base circle reduction.

I have tried two separate cams for my 1.6L PM me with specific questions.

Actually one set is for sale as well...
