Hi, im 18 and just massaged a carbed 305 into a 88 mazda rx7, it lacks something lol, I came across this website and would greatly appriciate any tips as to super charging my 305 with a single eaton m90, Im really hoping you guys can help, Im booed and hissed at in the rx7 world and then most muscle car guys scoff at me lol

IE:
-did you run an intercooler?
-how did you make your mounting brackets to mount them to the passanger side of the motor?
-how did you pipe your system?
-did you have to play with the advance? (Im only looking to run the stock 6-7psi)
-water injection? good or bad?
-Also a complete schematic of thje piping, ex: filter->sc->intercooler-> blow off valve-> carb box, hows that sound?
-Does my carb need to be prepped for the 6 psi?
-Will running V-belts be bad?
-The stock rx7 fuel pump pushes 30 psi, of course I have that knocked down to 5.5 psi for the 305 will I need to turn up the pressure?
- lastly hows the stock super coupe intercooler? any good?

Current mods:
-680cfm quadrajet
-Flow Tech after burner headers
-Removed PS/AC
-Weiland Intake
-2.5inch duals all the way back
-Custom machined alum. Drive shaft
-Electric fans
any help would be greatly greatly appriciated, Id be happy to send pics to your e-mail just let me know the address.

My e-mail is Rx7wheelman@yahoo.com

Also, if anyone can get their hands on a m90 at their local junkyard or something im looking to buy one that spins freely, they can be found on Ford super coupes, mercury xr-7's, and newer grand prix

Thanks a ton, Aaron

 

run a new cam with bout 500 lift port the heads if you can

 

excellent, any suggestions as to a company for the cam, or will any 500 do

 

No



my brother’s setup on a 5.0 ford… just made a bracket that held it above the valve cover and bolted to the accessory bolt holes on the passenger side head. Moved the passenger side accessories to the driver’s side.



right now it’s running with the timing locked out at 33 degrees and sees about 8-9 psi boost… of course the compression is in the mid/high 8’s with aluminum heads.



good if you have detionation



in a carb box… no.



for the accessories? Not a problem, but you’ll have a hard time finding v-belts that will hold enough power to run the blower.



it will need to be boost refrenced



Donno, brother sold it before the project was even started.

 

Why not a carb box? isn't a carb box the same as a carb hat? or carb bonnet?


what did you use for the fuel pressure regulation?

I have an extra accessories groove on my crank shaft pulley how could I convert that back to serpentine?

 

Carb box pretty much pressurizes the whole carb so no mods are required to it, where a hat forces boost through it and out the non pressurized areas.

His setup is fuel injected and used a T-bird turbo coupe regulator on an adaptor block that I made for it.

Grove- use an aftermarket supercharger crank pulley or weld something to what you have

 

so if running a carb I would need a boost controlled reg. to adjust fuel psi to the boost psi right?

thanks ahead of time guys, im a body man lol
