I am replacing my Intake manifold gasket and "o" rings tomorrow.

Should I put any kind of gasket sealing compound in the gasket????

Not really needed, just make sure to get all of the old gasket off. And, I do mean ALL, if you don't first of all, it will probably leak, and second you could break off a bolt in your engine tightening up the manifold back on, (ask me how i know).

 

Graphite Silicone is what you use on gaskets to help give them a little more omph

 

haha i over tightened a bolt in the water housing, that was a mess that i have learned from

anyways i also 2 was wondering about the gasket can i make the gasket out of my own gasket supply since i bought a roll of the stuff and have no use for it now. secound, i took my carb of the other day to rebuild and today i came up with the idea of porting the intake manifold. i have everything to do it and was thinking of using the gasket from the carb kit as a template to see how much i can shave off.how much of a gain do you get from porting the mani out and what else of a upgrade can i do to the stock carb to get some gains?.my whole car is stick right now and i have a chance to port it out but i dont knwo if i will jsut be wasting my time since i dont have the money to buy a good carb

 

Absolutley

HEHE I just did this the other day when I pulled mine down I saw how much of an overlap there was. So yea, you can port it but on actual gains I dont know.

 

thanks yea Im also not sure about the gains but its gotta do something

 

yeah...do that ... and let us know what the but dyno says!

What about just opening up that 2ndaries....could be fun....get throwen back a little more.

 

WAIT Id search a little before you go porting away, there are do's and donts of porting you intake manifold

 

yes I'm trying to find info but the search is being a real downer to me, but i get the rebuild kit tomorrow for the carb so iam gunna be doing this in the nexted week in abit. i knwo ther is so many guys on here with ported intakes i just gotta track them down to get ?s answered and like you said find out the do's and donts

 

We are refering to port "matching" and not porting something like you are thinking.

 

well Im thinking of porting like using a dremel to the wholes to increase them, which ever one of you was reafering to that is what iam trying to accomplish

 

Port matching is taking a part that is restricting from por design by its mate being designed a different size. So if 2 objects meet and do not create a = amount of surface openings you port one to match the other. General porting is enlarging evrything and machine every bit you can out to make a larger opening to improve flow beyond stock capabilitys.

 

Talk to Carl, I know they were investigating and flow testing ported stock intakes over at PB&J.

 

this is the one Im Aiming for. any info for me. Im not alone doing this either the guy rebuilding my carb is a family friedn that builds high berformance engines so he ports out alot of **** but i was gunna try my crack at doing it with the help of this guy he will draw me the lines and ill take it home to port. the only thing is he has never worked with a rotary engine but we are only gunna be dealing with the carb and the intake so no biggy
