3800 M90 Build

Ok the cats out the bag!!im going supercharged .its a 3800 gm m90.i need lots of help as im a nos guy.for starters my list of mods is in my signature.the guy im buying it from ran it on a stock tuned motor at 3psi.first question is what is the "safe" limit to run boost at?i know it is not ideal but i have a wide band O2 and will be doing tuning very soon.i also will be trying to have my company make a new lower intake mounting bracket on the cnc machine and have it taped for nos/water meth injectors/spray bars.i will also be getting a p+p unit from 3800 performance and stepping down on the pulley to try and run 8-10psi.what size injectors should i run for that?which fuel pump should i run?any suggestions on tuning?i was going to go mega squirt but i see sct has a new chip out,any suggestions?

ported and polished gm 3800 gen 2 m90
Water to air intercooled
port matched 76mm inlet and intake tube
mustang 75mm race tb
90mm maf
36lb injectors
255 fuel pump

Well the plan for now is to cut the hood.then I can see how big of a cowl ill need.I have a 3" body lift in the explorer and its tight.but I also have solid mounts that raised the motor up about 2".from the looks of the ranger I won't need mounts that raise it, I'm actually going to try and build a set that lowers the motor some.but hell I think having some of the supercharger sticking out the hood my look cool and probably help cool it some, just can't drive in rain or the belt will slip;)

Yea the supercharger sticking through the hood would look cool you should try putting a 8-71 weiland like http://www.dyersblowers.com/1694.html and if you have one of those you need one of these http://www.alsblowers.com/streetcatcher.html :thumbsup:

So what does that mean?what needs to be done?i bought this pump and kit.does it have everything i need
http://www.redlinemotive.com/part-number/walbro/gss307-400-812.asp

Just a little update about this because I'm looking for one for my ranger now and I'm not going to reuse this one.they make a couple different 255 that fit, the walbro one you wanna use is the gss 340.I bought the gss 307:(basically the same pump but one performs wayyy better.this go around I think I'm going with the TRE 255.its gotten really good reviews and now with everyone making fake walbros you really don't know if it real or not.at least with the TRE you know its real.

Good read
