I have another question regarding the Aspire 1.3 into a Festiva swap. Since my car is a stock, daily driver, is if benificial to leave the stock cast iron Festiva exhaust manifold or should I try to use the tubular exhaust manifold that came with the Aspire engine? I've read that the stock manifold helps bottom end and the aspire "header" kills a bit of bottom end, but makes up for it in the midrange. Any real world experiences??? Which would be better for mileage?

'91 Festiva with roller cam '97 Aspire head. Still wish I could do burn outs, but the mileage is nice!!! -
If I had to choose I would use the tubular aspire manifold. It has good torque from 1500-3000rpms then the hp was from 3000-5000rpms. -
Honestly, I doubt you'll see much difference if any. I would probably keep the cast iron Festy one... just to keep it simple.Brian
