I was asking some of these ?s in a earleir thread this week

What upgrade can be done to the stock carburater to get a little more hp?

also I'm wanting to port out the Intake manifold and was wondering what the do's and donts are to doing it?

My carb has been taken off to get a rebuild done to it, so i was wonder what mods can be done to it and the manifold while i got them off. I got everthing to port with and the rebuild kit just waiting so any info would be appreciated

thanks

 

com'on anyhting?

 

anyone?

 

Send it to sterling! Its the best carb mod you can ever make!

 

I believe RX7carl is porting the factory intakes.

 

what exactly do they do to it

 

when i ran the stock setup, i used the gasket to port match the intake to the engine. then wired the secondarys to open manually.

 

I was planning on using the new gasket to see how much i could shave off

 

here is a good pic of what they can do to a carb

i seen that searching around, Im getting my carb rebuilt tomorrow probely, and its getting done by a pro so im hoping he will have some answers of maybe getting a bit more hp out of this stock carb. and for porting the intake manifold i think ill just make the wholes abit bigger and hopefully it will all work out in the end

 

okay the carb got rebuild today, no upgrades to it, still alittle sketchy about porting the intkae manifold though

 

Listen to the rest ...sterling is the way to go ... as soon as i'm done with my sp rebuild I'll be getting my carb done through him.

 

Well, if you search theres some good stuff written by Sterling about the AP mod, also mech secondaries will give more power. I wont say exactly what I do to the manifolds. However if you want to go it on your own, start learning how the principles apply to it. Doesnt matter if its a piston or rotary, all engines are air pumps. A bit of web searching will get you lots of good info. DONT just hog it out. I made that mistake years ago when I didnt know better. Top end was great, didnt run worth a **** anywhere else. Not good for an AutoX car which is what I was doing at the time.

 

What if you have a '79 manifold available?

 

Holy ****, it's a damn REUNION! :P

 

Alright the question I have is what do you do when you use the 79 intake manifold on a newer engine? How do you block the bottom emissions port?????
