Depends what power your after and what you want to use the car for. I don't think the lag on a TD05-18G is bad atal and you can hit about 350. GT28/30 depending on what spec is going to make you a lot more lol!
Yea don't bother with an adjustable fpr..i just asked as if you had one, and someone had ramped the pressure up, that'll make the injector tick considerably louder.
Well no a 20G will have more than an 18 and 16G. The billet wheel'd equivalents will be less laggy due to lighter comp. wheels. What GT28 were you looking at?
Nothing massive to report atm! Changed the head unit and rewired it all as everything was connected up wrong. Some pics from the other day now its back together..
