ok here is what i'm thinking, i want more power...yeah im power hungry, but i think i wanna stay na and i want it to be able to stay streetable/dailydrivable...so i have a webber 48 ida, im looking for an intake and exhaust. My questions are should i go streetport or bridgeport-its ok if the engine only last 100,000miles so i know bp is gonna be way more power but will it be dailydrivable? and what is the low end throttle/rpm response like? second what type of exhaust should i go for if i go bp...will the rb sp exhaust allow for full potential? and the rb intake for the 48 ida, same question will it allow for full potential, or will it need to be ported to match the bp? any and all info on the subject or advise/thoughts will be very helpful!!! pls no suggestions to go turbo, all tho it would be fun i know boost is addicting and id be way out of control and i like na, when i beat ppl i wanna be able to let them know they were stomped by a carberated, 1.1 liter na....sorry for the long post and thanks

oh yeah and whats the difference between an rx-3 12a and an rx-7 12a? it'll be a completely straight swap right???

PP's can be streetable

onslaught_81

hahaha, yeah i never thought of that, but id be outa control with that too, even though thatd be freakin sweeeeet!!!!

I'd stay away from bp or pp on a street car, it'd be useless on the lower rpm, also, if you are from cali, you might want to take smog into consideration, there's no way be able to idle at 700-800 rpm as required by smog test on bp and pp, maybe, maybe a mild sp would be the best solution.

im here with the military and while on x-mas leave i plan to register it in texas where my 1981=25yr old car wont have any smog rules, so smog isn't a problem

Zyrano

that's cool (i wish i could do that, smog sux), but streetability is still an issue, since it's gonna idle high and rough and anything below 3-4k rpm is like useless...

onslaught_81

zyrano is that with bp or pp or both cause i dont think im looking for that basically cruising at 4k just to go 10 mph??? i dont know, i dont know that much about bp but i do know pp is definetly not an option for me that is a track only type deal in my opinion

I'd go with streetport...rb header...3" titanium exhaust off of your rb header to whatever muffler you want...you need a lightened flywheel...short throw shifter...and maybe larger injectors...tII coils and ignition...all the small little things you can think of...you'd be surprised where you can find alittle extra hp...

onslaught_81

do rotary's not need back pressure? but yeah thanks for the suggestion never thought of a 3" exhaust off the header.....and what do you mean injectors? it would be a carbed engine....sorry if that sounded a$$holish, dont mean for it to

dirty86

heck do a big streetport if your getting a 48ida and port the exauhst too so it will sound secksy

then add a little 50 shot of no2. just for that extra highway fun

onslaught_81

haha...hell yeah ill start with 50 then eventually ill be at a 350 riding around town blowing up an engine everytime i go for a joy ride, but if i had self control when it came to speed thatd be a lot of fun

Lee Lyons

should have said 2.5" titanium exhaust honest key pressing mistake...I run 2.5" exhaust with 2 presilencers with a magnaflo at the end...I have EFI in my 12at so I have injectors but you could get bigger jets for the carb...

onslaught_81

do you have the jdm 12at or did you do your own custom efi thing???
