carborated forced induction?
I had a question, I have been building a turbo for my 95 civic and reading this forum has taught me just about everything I need to know. I have about 80% of the kit and am slowly getign everything ready.
Recently I decided to turn my old car into a race only car.
Its a 83 RX-7 and its carborated. I want to throw on a turbo and make that thing scream but I was trying to figure out what I would have to do to get the fuel system ready. In my civic I know I need to upgrade fuel injectiors and such. I have a 450 CFM holly carb on it now, would I just need to upgrade to a better CFM carb for turbo?
anyone have any experiance in this?

I have an 83 rx-7. I have read about changing all the lines for a fuel injected motor. IT SUCKS! you might know about it. You have to bend all new fuel lines and put in a new fuel pump and that jazz. Even then to motor doesn't fit right. You shifter will be back 3". Oh if you want any parts for it just pm me. I am parting it out.

Re:carborated forced induction?
why the ---- is everyone so scared of carbeurators?
they're very easy to boost with, just get a bigger carb, or bigger jets, put the carb on the intake side of the turbo, and off you go.
shouldn't be too difficult, it's been done millions of times.
it atomizes the fuel so you end up with a nice combustable even mix, you don't have to worry about cylinders and crap cause it's a rotary.
---- what all these pussies say, especially whitey, he's one to talk, he twin turbo'd his civic because people told him it was a bad idea.
pick up a copy of corky whatshisface's Maximum Boost or whatever it's called. it's got all kinds of info on how to properly turbo a carbeurated engine. i read that chapter, and it seems incredibly easy, maybe moreso than fuel injection even. you just have to understand how carbs work really.

The difference is Whitey is talking from experience, you are talking out of your ***.

There's a big difference between reading about something than actually having experience by doing it. You are by far the dumbest mother ****** around. Anything seems easy if some dipshit like yourself simplifies it. The only thing that is truely easy in life is your **** of a mother. What you said is like me saying, "on an EFI car all you need is the correct size fuel injectors and off you go." Douche bag morons like yourself who doesn't know anything shouldn't be giving advice cause you read a book. You obviously never worked with a carb so shut the ---- up. Nobody's afraid of carbs, they're just obsolete technology. talk to anybody who has to constantly change jets for temp, altitude, barometric pressure ect will tell you exactly how easy carbs work with turbos. I hope you get aids and die cause you are the most worthless sack of ---- around. I'm glad you know me and know why I do what I do. ---- you and your whole family.

Re:carborated forced induction?
My neighbour turboed his carbed Peugeut without even turboing any thing before that.
What was really easy IMO....He has a drawtrhu carb from an old renault 5 turbo that he uses. and a FMU.....you need a fuel pump though. but it was fairly straight forward.
the only extra work would be a return fuel line...fuel pump. Although most people when they turbo they FI engine they also replace the fuel pump. Just make sure your carb can spray enough fuel....and get a WB02 or at least an A/F or EGT

Re:carborated forced induction?
I appreciate all your replies, it seemed to me that it shouldn’t be to hard but I have no experience in it.
I already have a Holly 450 CFM carb and would upgrade to at least a 650CFM or a dual side draft, I don’t know a ton about carbs yet so..
I already have the full race header and dual primary full race exhaust from RB so that should be ready to go.
It defiantly would be the intellectually easy path to swap in a 13B but that’s not exactly the cheapest route ether.
I have decided it’s never going to be a daily driver as my civic had that down so im striping out the interior and want to see how fast i can make it. (And in true HMT style for the least amount of $)
