NA builds. How far to go?
Hi all.

So in a few months ill be taking my engine out as it needs a refresh and I'm after some more power. I'm looking to stay 16v and go ITBs. I've had a read over Bill Sherwoods page about power build but wanting to get some feed back from people that have gone for power and more up-to-date info.

I'll be forging the bottom end and putting the compression ratio up but not sure what to do with the head work and getting mixed feedback, The head i'll be using will be a blue top and most likely be going for a Link ECU. I'm wanting to aim for a min of 160hp.

Cams are a sure thing but no idea on what size to go for. Would you uprate the valves springs and over size the valves or just replace with OEM parts. Some people say that OEM valves and springs will be good for 180-190 others say that they need changed at 160hp.

Also, Has anyone done a power build on a 3 rib block and 40mm crank? A lot of people say go 7 Rib and 42mm but I'm not seeing any bad evidence against the 3 Rib.

Car is a road legal car that only gets use at the weekend and a few trackways a month.

What have you done and how have you found it? I don't want to find that i've replace/uprated and to find that its having negative effects more than positive.

Thats my ramble for now. Any help would be great!
