i'm running an 18g right now and i just got the internal wastegate welded shut. i'm also running a blox b series turbo manifold with an ultragate38 external wastegate. here are my mods. .

hondata s200b all options
dsm 450s
aem fpr
blox t3 flanged turbo mani
turbosmart ultragate 38 ex. wg
skunk2 intake manifold
greddy 2.5 to 3 in downpipe
greddy evo 2 exhaust
greddy manual boost controller
greddy type rs BOV
precision 375 fmic
greddy 18g
1.75 hot 2.25 cold ic piping


@ what psi would i need to make 300 whp? that's my goal. i remember talking to greddy a while back and i remember marshall saying that the max amount of psi that the 18g is able to put out is around 26 or 32 psi. would i even be in this psi range if i wanted to make 300whp?


any info would be great. thanks a lot guys!!!
