headers for 1uz midmount ariel atom.

[ReinierWelgemoed]

Hi folks

I have made a full post on my project in the fabrication section but like to ask here about header soec.

I have no space constraints at all and im looking for specs on 4-1 headers that will yield best top end power on 1uz vvti... lenths of primaries and diameter.... will be runiing itbs and flowed heads with standard cams. I have space to build the ultimate headers so i would like too build them to be real show pieces as well...
Regards
Reinier

will all depend one if you do any modifications to the engine, cams, porting, intake...

If the motor is stock my feelings are you wont see any worthy gains due to the stock cams and intake over any header that is not restrictive.

save the money for pistons, rods and a nice supercharger!

Heads will get fully worked with 268/274 cams and itbs...
