I just bought a decent 90 vert' with 115,000 on the clock. It has a B series transmission in it. The body is pretty good. Only 3 quarter size dents and 99% rust free. The driver side window doesn't work and the top is trashed. It leaks like hell. It has a RB header and custom exhaust. The paint................ well what paint. Its faded to hell. Anyway the car is in Melbourne right now and I will drive it home to St. Louis this december. Until then I m going to park it under a cover. Anyway I have researched supercharger setups on here and everyone seams to give up or get shitty results. I am basically going to get a T2 block and SP it, throw in the T2 tranny and rearend while I am at it. Now I don't have much experience in the 2nd world but could you put a Jaytech manifold on. Such as this one:

Then put on the whipple supercharger. Then put this ontop of the blower:

Then just throw a filter on top and hopefully it will clear the hood.

I will be running a methanol injection system on it just like my FD so I will be running a decent amount of boost. I won't be kidding around here with 5-8 psi of boost. Definately turning it up to 1 bar or so. Also going to spray it with a good hit. So anyway is this intake/blower setup possible of am I dreaming here???

Thanks,
Phil

Good luck man, but you are looking at a lot of fabricating here. Hope you stick with it. Would like to see the results of a whipple on a rotary.

go for it! id love to see the results. the racing beat intake manifold is cheaper though.

Darn, we would be able to caravan back to St. Louis, but I think my car isn't going to be quite ready yet unless my mechanic quits his regular job and finishes my car early.

Yeah, right, lol. You may want to spread out the components laterally so they will fit under the hood. I'm sure you will be able to figure this out once you have the car and can see what you are working with.

Unlike the Roots blower, the Whipple type has an internal compression ratio like a turbocharger. This means that you can intercool the system pretty much like you would a turbocharged car. See here for an example on a Miata, especially noting the proper use of a bypass valve and air-air inercooler:

You have Searched well! Most of the failures are due to the fact that the people on this forum have absolutely no engineering background and attempt to use an incorrectly sized supercharger, or they screw up the installation by trying to hang the supercharger on the intake manifold (big no-no!) or they skimp on the pulley braces, or they try to use a cheapie induction system rather than simply using a good name brand standalone EMS. I highly recommend Corky Bell's "Supercharged!" book so that you at least have a general idea of how to go about this conversion. Also, a phone call to the supercharger manufacturer would help with choosing the correct size for your engine and boost level. Why people think they can eyeball the sizing is beyond me.

I think it is possible, but you will probably need to have a custom manifold made to mate the supercharger discharge to the throttle body. You may luck out and find an existing manifold that will work, but it may be easier to just make one rather than spending months searching for something that will work.

Yea, I definately want to still do it. I will probably call Whipple and ask them what they can do once I get the car home in STL.

I've used what is now the W200AX on a '89 vert a while back. Honestly, it was a waste of money. Sure it had a flat torque curve but for 1/4th the cost it would've been a lot better off turbo.

Well seeing as how much this is going to cost I am ditching the idea. I could get way more power out of a turbo setup for wayyyyyyyy less $$$. Anyway I will proly just do a half-bridge setup just like my FD. I have searched for some badass ITB setups and haven't had any luck. I am not trying to make this thing a beast like my FD. I just want a good cruiser with some power. Anyway anyone know of any good ITB setups?

Try these websites for th ITBs. www.efihardware.com or www.fuji-racing.com. I got this info from this thread https://www.rx7club.com/1st-generation-specific-1979-1985-18/fuji-racing-itbs-finally-d-683967/. It has to do with first gens but it is relevent info with some other links to websites. Just trying to help. -Jeromy

Well heck, I could have told you that from the beginning, lol.
