Ok So I have an 03 s60 non turbo.
Debating whether I want to sell and buy a T5 for more power.
Talked to VMS i believe and they said getting a head done by them port polish etc and shave the head to increase compression and run methanol injection will increase power considerably. Seems like the cheaper option.....im wondering if anyone has done it. Also...Id want some type of tuning. Due to the "fiber optic" wiring in the s60 could i still use a megasquirt for fuel tuning? Anyone with experience please let me know....the internal engine mods section seems dead.

 

1. DO NOT BUY FROM VMS. They are a rip off and they are not quality anything. Trust me when I say this I have seen their work and it SUCKS. And customer service is bad as well.

2. Sell the non turbo and buy a turbo model.
