fuel management

[flyboy367]

so im starting messing around with my 95 maxima se. im getting nowhere fast with finding a supercharger for it. planning on doing some looking and reading about a turbo. is there any good info on using a apexi safc to control the fuel/timing. i know nothing about these. im used to either turning some screws on the carb or downloading a program for my gtp.

i'm not sure about timing but it automaticaly adjust the air/fuel mixture so you don't lean out when boosted. stillen used to make a sc kit so maybe they still have some burried in their back room. i'm thinking about retro'ing a gm sc on mine - a lot cheaper though more work and possibly cutting out a piece of the hood involved for clearance.

well the m62 is the little one and available. also used on the exterra i belive. there is a smaller one used by mercades with the same output. its also on a clutch like a/c compressor. might make things intresting. or just bum a m90 from a gtp buddy of mine and have at it. let me know what your doing cause im down for some homebuilt stuff.

i was thinking about an eaton - supposed to be pretty durable - and a fabbed up adapter to mount on top of the lim. i thought the newer sc gm's had the eaton and older models went with m90...but might be wrong. i can't get enough time to go to a metal shop and see how much they'd charge for making me an adapter. i also thought about using a bigger pulley to run 5psi wot but since the stock puts out only 9psi i might leave it like it comes. one thing i thought i might need is a longer snout to clear the timing chain cover but i'll make measurements sometime for that. i think the injectors and, maf and safc will come out to be more $ than the used sc and an adapter

the series 1 gm 3800 had the eaton m62 supercharger. the gen 2 3800 in the gtp has the eaton m90, from 05+ its a gen5 eaton m90 which is even more badass then the m112 that came on the lighning. if i could see some pics of the stillen kit installed i migt be able to start on something. i think the xtera is a good place to start to see if a manifold swap would work, also the crank pully would be needed. for the work involved making a sc fit maybe a turbo is an easier route.

the m90 eaton sc used on the ford supercoupe might be a decent choice. if you could mount it to the rad support and make the blet system work youd have a intercooler and all.

you have to make sure that the SC spins in the same direction and mounts on the same side. I believe it is counterclockwise and the other part i forgot lol. From what I heard is that most people use Vortech blowers. There is a guy on the .org that sells the mounting plates and there is a thread with everysingle part needed as well. It was taken of the Stillen Kit's instructions

turbo would be easier because the kits are available. the one thing i don't want to add with it is additional heat in the engine bay. the stillen sc looks like this mounted thanks to nj1sh's digging:http://www.geocities.com/jgadlage/furious.html

it's set up like a turbo. don't like what they did and want mine to sit on top of the intake. the gm sc from 2000 bonneville will mount on the same side and if i have to...i'll make it spin the same direction plus you'd have to dump about $4k for a turbo kit. here's one:

btw...thx for explaining about eaton. the one i want is m62 - simple and dependable.

i didn't know they still sc the gp. they stopped that on bonnevilles in 99...what a shame Modified by allensteiner at 10:15 AM 6/23/2008

you will want up to 1996 bonniville for a m62, in 1997 they switched to the series 2 3800 and the m90. i used to work for gmi was contemplating turbo ideas last night. have to look under the hood to see whats what

[allensteiner]

m90 it is then. or a turbo modded into a supercharger...i can't decide yet. i know the overall cost of the mod is going to be the biggest factor. especialy that i'm not thinking about going to the track with it. just want to have a max that's built like not many others around

[flyboy367]

go turbo then. less making stuff work. just get a set of headers, block off the rear manifold and add a t to the crossover pipe. put the turbo where the stock air box is and run pipe to an intercooler. add a hood scoop for fresh air and heat dissipation and your done. lot easier then finding someone to fab a manifold
