Vortech Exhuast size and bore size
Hi,
Setup b16a2
GSR Cams
Vortech + aftercooler crv crank pulley and 10psi pulley = around 15psi at redline.
Hondata s300 / saturated 750s
Blox IM - still to purchase
Kamikaze header + 2.5" downpipe - still need to purchase
Qulife LSD - Still to purchase
DSS Stage 2 Axels - still to purchase
Now I was thinking of sending block to earl from laskeyracing to get it sleeved and bored to 84.mm and using cp pistons to bring it to 9:7:1 and also sending the head for the full port polish and valve train upgrade, basically there stage 3 work that goes for 1500 dollars, and my question to you is what postive and negative effects will this have and also what exhuast siz should i go 2.5" or 3" {if 3" iam going thermal}
Please note iam from gibraltar and no one here rebuilds engine or sleeves so i need to send out the block so might aswell be earl since ive heard hes one of the best and yes i realise turbo is better but i went this way and iam going to stick to it now , next time if i ever get another si i will be sure to go full race.
