intake questions

[blackbombshell95]

i think the 2000+ grand ams 3400 heads are the same as the 2000+ 3100 heads right? both aluminum from my understanding. so i have a 3100. and i want to do a 3400 top end swap. is their a difference between a 3400 topend swap or a NEWER 2000+ 3100 swap? or does it matter?



should i use 99 grand am intakes or 2000+ intakes? i heard that the newer intakes are better somehow....





whats a really good gasket set i should get for my car if i use the 3400 parts???

3100 and 3400 upper and lower intakes are excatly the same 2000+, only difference is the lettering on the plenum

keep in mind upgrading to those intakes you will need to block off your EGR.

[EspanolaGuitarista]

If I block off the EGR then how do I pass emmisions? I'm in California and they get very cranky when people tamper with emissions parts.

[geoffinbc]

You dont need to block off EGR. Just make an adaptor plate.

[blackbombshell95]

i will need an adapter plate. still i can't find a person who i can pay to make me one. which sucks.

[geoffinbc]

You can pay me and lloyd Or we can show the images of one and you could make it

[bu01]

[geoffinbc]

[blackbombshell95]

well how long will it take you to make it? just name a price.

get the 3400 heads they are slightly bigger than the 3100 ones and then get the 00+ 3100 intakes and get them P&P. oh btw u dont really need to get the heads off a 3400 it wont really be an noticable difference unless u get stage 2 heads ect.

Whats a "stage 2" head?

'00+ 3100 heads are the exact same as all of the 3400 heads. Unless you are talking pre-'00 3100 heads........

[MasterJacko96]

stage 2 heads would be like heads that are P&P 5 way valve job, milled heads, ls1 valve springs stuff like that

[blackbombshell95]

i already have 3400 heads in my closet. who can help me get an ls1 setup? what are the parts numbers?

[Berettaspeed]

why not use the 3400 heads and keep you 3100 upper plenum?? or if you want the 3400 plenum get a 97-99 upper plenum from like the dealer.the 97-99 3400 upper intake should work as far as you needing your EGR to work. i passed emissions with my car not having an EGR but you have tail pipe emissions like i do so you might be able to pass. what are your test limits???

just wondering where did you get a chip from?? my friend looked for one for his 94 GP,and from my understanding 3100s ECU dosn't have a chip. i never owned a 3100 but this is what i heard.
