ported

Hi all, Been enjoying reading this thread. I have a question. I am about to build a sub enclosure for my Toledo... I mainly Listen to DnB, Jungle, Techno, Hardcore, Breakcore, Dub, dubstep and Rock/Metal, but the question is do i build a ported or sealed box. What would sound best with these...

What gains would you get from fitting a big ported head from an AGU Golf to a AQX Ibiza. Would it be worth doing?

I'm considering a ported and polished head conversion and a remap from tsr performance. My lcr 225 is standerd (other than the s3 upper strut brace) at the mo and the only thing i was going to do was a cc or p tourque re map and a forge diverter valve, but a mate had his done on a 2ltr mk2 golf...

what would the cost be to port and polish my bam 225 head and what increase in power could i expect on an engine already making 300 bhp with a k04 hybrid, full 3 inch dp and exhaust etc. Cheers Dave

Hi guys, firstly Ive searched but havnt really found an answer.. after watching top gear recently where they tried modding a renault avanitme they claimed a large bhp increase (to get the car back to the listed bhp), by getting a new inlet (among other little bits) So my point i guess is, do you...
