300-350whp JRSC'd gsr w/N20 possible?
so ive seen stock gsr's make 300-350whp with out a problem on turbo applications but have yet to see one with a SC and nitrous...with the amount of torque that may be created by such a setup, would this be safe? i plan on reaching this goal in the near future but i wasn't sure if my stock block would handle this?? has anybody seen a setup reach this goal without modification to the SC or motor? here the setup i have in mind:
stock b18c
255 walbro
JRSC on 8-10psi non intercooled
rc 550's (should i go bigger?)
NOS wet shot (65-75 shot) plumbed before SC
aem fuel rail and FPR
NGK bkr7e's
4-1 header with 2.5" collector
2.5 " straight exhaust (should i go bigger here?)
hondata IM gasket
68mm TB
ITR intake cam
cam gears

I think you might with a better set up! the max boost you can safley boost would be 9psi although since nos will be in the mix you might be able to go a little more but think about this, get a better header!! tri y replica would be a better choice than a 4-1, , get the lht water intercooler setup that way you can boost over 9psi which is the stock jrsc max psi before det. becomes a matter, this would greatly help you reach that goal and help keep it safe, iat's stay real low with the lht, so with that, boost around 13-14 psi!, also swap your stock gsr intake cam fo a itr intake cam this is a great combo for the jrsc, a bigger tb at least 68mm, a hondata gasket, and what intake are you using? i love my comptech ice box, your injectors should be fine you can always get 750cc injectors they can tune them down if needed check my thread out im shooting for 280hp with out any major mod to the jrsc!!

Most guys run a small dry shot through the blower. I dont know much about the b series kits is there room for a direct por kit in the manifold??? or the nozzle kit..

Theres a few spots the best imo would be get a tb spacer and connect the nos nozzle there cause the spacer provides a tap.

it also wont help in cooling down the SC and i want to get as much atomization of the nitrous and fuel as possible for an even flow across cylinders.

My good friend made 298whp on his stock sleeved b20 bottom end/ stock gsr head. He had forged pistons, and rods. Had the 9psi pulley and a 50 shot i believe. 93 octane. Car ran 12.6's all day long on 22inch slicks.
The car over heated i believe and lifted the head.
It was a FUN car to drive!! Good luck

IMO it is possible with excellent tuning and good gas.
Internals make it more reliable and oops proof.
Any detonation though and say good by to your ringlands.

ok so assuming the motor is built, how large of a shot do you guys think the SC would tolerate? could i be able to run a 100 shot wet through there?
