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!!!

 

No not even past 20 with a good tune

bump for helppp

 

i've seen at least one b16 making just over 300whp with an 18g but i don't remember his setup. i know it was running hondata too. that was on a stock block. won't know until you try. are you trying to figure out what size wastegate spring to get or something?

 

time to start thinking about bigger injectors

roughly, what would be the duty cycle for the injectors at high boost? and what size would i need?
