Cylinder Heads Na / Turbo

[sexual harrassment panda]

different design for fuel/air path, trying to make a swirl in the combustion chamber

different design for coils in the way they are attached.

rocker covers not interchangeable

Think there is something listed on Atomics website about the differences between BF and FG heads.. Something about port design to increase swirl..

Had been searching for an FG Head with the thought of getting it ported and flowed to save down time of my car being off the road.. Heaps of cheap NA engines around, however XR6T engines are way more expensive..

Wonder how hard/extra work involved there would be to modify the NA head for the same results?

if you go bigger valves and seats it would be worth it

I think u got it all captured shp

I was just wondering if there was any more

I have a dream of one day building up a na fg block, can be had so cheap these days and obviously minimises down time, one thing I was worried about was thickness of the block. I thought I read somewhere that 2 out of every 5 blocks are too thin in parts and arent worth building for decent hp is that true?

[JETURBO]

Very true

that's why sonic testing is so important

[XYZ]

Yes, but think you would be pretty safe with low km motor.

budget $100 to $120 per exhaust valve, b series turbo heads new off the shelf from fraud are around $2400. Have you priced an Fg unit from your friendly fraud dealer? It doesn't take long (with a b series head at least) to rack up the cost of a new head converting an NA to T
