i wanna turbo or supercharge... but got some questions

I have a 95 mx6 with the klde engine. and I've turboed many different cars. from honda's to spec v's and 240's. but not a v6. its been a couple yrs since i turboed a car so I'm a lil rusty. the main thing i can't remember is what to do to relieve the positive crackcase pressure. what do u do to relieve it. and where in the world could u find a kit for a suprcharger? I thought mr speed kit, but i couldn't find em off google lol. still thanks for lookin and ill post more questions if i got anymore.

All SC setups are custom.. Back in the day a few different "people" not company's made some..

Crank case pressure..just route the PCV to the atmosphere, and leave the big hose on the intake elbow disconnected. This is the easiest way.. Unless your the Anal type and believe your motor is going to blow up..you can get a PCV for boost and route the big hose to a catch can.

Turbo, bare bones elcheapo setup all you need is turbo,pipes,wastegate,bov,fuelpump, fuel psi regulator, fmu and some 3 ply couplers.

Ahh so that's y its so hard lol. thanks for clearing that up. i think i know u! well ur car. is it on youtube? If it is its a b.a. car man. ok next question is injectors. stock injectors ,a 12:1 fmu, a 255 pump, and afpr would that be ok for 5psi?? and if not what's the next best injectors besides millinea s injectors? cause i can't find any at the moment and we don't have a fab shop here in scottsville to do any fuel rail/injector fabbin lol. and i just moved up here from tn lol.

Mil S injectors are the only ones that will drop in and be ran be the ECU. All other injectors either need to have the stock fuel rails modified, or new fuel rails made, along with something like Megasquirt to control them.

With Mil S injectors on a FMU, you should be able to hit 6-7psi safetly.

But your MPG will suffer with Millennia S injectors because you will run very rich when you are off boost daily driving. Unless you have something to control them. Like s-afc. Which I read will not work on KL engines because we ignore VAF Signal at WOT. Stock injectors should handle 5psi if I'm correct

Could you use s-afc to control the fuel input on partial throttle, where the fmu is bad, and then use the fmu to control fuel input at WOT where the ecu ignores the s-afc??

I was thinking, millenia s injectors, controlled with s-afc until WOT, then an 8:1 or 10:1 fmu for wot. The safc should let me keep my gas mileage when off boost right?

To answer my own question, yes. It will. I'm running it now with no problems. Good AFR under boost and cruise\idle. 26mpg with 310cc millennia s injectors and vortech 12:1 fmu
