3100 - Large Port Intake Swap
From 60DegreeV6.com
Jump to: navigation, search
Procedure for swapping 3400 or 00+ 3100 intake manifold onto a 93-99 3100.

Coming soon...


i need to know every detail, but i cant keep posting every little question... im doing heads too, so i have to know everything... i want to take pictures throughout that might be useful here

Buy a haynes or chiltons manual for your car. Tells you how to disassemble and reassemble everything, as well as torque specs. Heads and manifolds arent hard to change at all. Its more time consuming than anything. Make sure you label things as you take them apart, so you dont forget where they go. Usually it isnt too good to have it all put back together and a pile of bolts left over.

It's nothing to do with how to do it... I work in a shop. I repair cars all day long every day... what I don't do every day is swap different parts into cars from different engines and get to do all the FUN stuff with automotives.

No, this was just a hint that the info for the wiki on the 3100-3400 top end swap needs to be up like the Gen II to whatever that was is up. Sometimes I ask a question on here like;
"I have 2002 3400 cyl heads, will they work on my 1997 3100"

I get an answer like;
"3400 = 2000+ heads"

I get that, and I appreciate the answer, but it doesn't answer my question of whether I need pre-2000 3400 heads or if I can use 2002 3400 heads. On top of that, what happens with new head gaskets... which ones do I use.
I'm doing a swap that lots here are kinda beyond, and I get that. It's like when new shoes come out and you don't get tham for a years... by the time you get them nobody gives a f$%k about them shoes. So, I noticed in the wiki that the info is VERY comprehensive and covers any and all prolems and options. Thats why i am dying to have that.

It drops right in, no problem. Follow the directions as if you were using your stock parts instead of the newer 3400 stuff. Only issue I forsee is the coolant line to the lower intake may be threaded instead of press in, but you can thread for that or use the press in pipe instead. EGR has to be the newer type.

No one is really in charge of articles. Its a community effort.

thank-you

Unfortunately, it usually ends up being Ben or I who put together the articles. And both of us have been busy for the past year or so, therefore just don't have the time to do all the grunt work anymore. That is why we keep TRYING to make it EASIER for the MEMBERS to write the articles. But as you can see, it normally never gets done...

[IanSzgatti]

well i'd like to do it when i get through the process. i'd use the same ground work as the article for genII to genIII conversion. that artical is very clear and complete as far as I read it.

it's things like needing a different egr, or different ways of overcoming the coolant line for various models that i'm not solid on. As far as I know, it would be necessary to use a new egr if your going from 97/99 3100 heads to 2000 or more 3400 heads and manifolds? ok, see...(laughing). I guess it takes while to put together all the peices

[SappySE107]

Yup, 2000+ EGR uses the same connector but you need the egr and the egr to exhaust manifold tube (unless the original can be bent). Small port are all threaded coolant line as far as I know. I think all large port is press in but I am not 100%

I have written a lot of articles over the years but for the past year or 2, its been difficult to find the time to take pics and write the steps down. That and I haven't done much other than performance work.

[IanSzgatti]

listen, i have a question for you... i've been wondering how these changes:

-3400 heads
-ported 3400 manifolds
-modified exhaust manifolds
-aftermarket intake
-high-flow cat/muffler

might effect my emmisions test. many people on here modifying cars, and i never hear about smog testing. is it that the smog tests arent required where you guys are at?
where I am in Canada you can't sneeze out too much CO or your in shit. I REALLY want to get a deal on all these parts, and make a nice project out of it... but im worried that when the smog testers run my serial number, the computer will think my car is messed up? Am I missing something?

one last thing, who is Ben? would he give me a nice package deal for the things I need shipped? Because if I can do this stuff without an emmisions concerns... im breakin out the MasterCard. I appreciate the info you've given me so far, thanks.

[SappySE107]

Im Ben:P MPRacing has cats and mufflers, and I do business with Mark. Not sure what kind of package deal I can make but I do have an intake manifold package on my new store.

If you don't want to deal with taping the LIM for the coolant fitting, or making up some other fitting from the new and old pipes, you can get a 96-98 3400 LIM from a van, they are already tapped.

For the upper plenum, if you go 2000+ you'll need the 2000+ EGR and flex tube. If you go with a 99 or older 3400 plenum, your old EGR will bolt up. But the older plenums necks where a bit more restrictive.

As long as you get the engine put back together and the EGR is functional I don't think you would fail at all. Drive around for a while so the ECM adjusts and you should be ok. If you went really radical with cam or headers or something then you'd need to get a tuner and tune it to be bang on again.

Ben = Sappy


My setup consists of original 94 3100 heads and all, ported 1997 3400 Venture Van LIM, and ported 2005 Malibu Maxx Plenum. I have an EGR adapter since I can't just swap to the 2000+ style like you can but the computer throws no codes and drives great. We don't test tailpipe emissions here but I have no doubt my car would pass with flying colors.

[IanSzgatti]

I think what I really want are some 3400 heads and that street ported kit for 96-99 3400s... I have a 56mm TB now, but i'd go for the 62 if it would fit on the opening of that 3400 upper... I think the biggest difference will be had with the TB... thats huge...

I assume that the kit in the store here (96-99 3400 manifolds) have the press in style coolant fitting and will work with my EGR... so i do believe I have myself a workable set-up.

Hi!

I am new here but I have been lurking the forums for a few months getting ready to do an engine swap on my 89 Cutlass Supreme. I was digging through a bunch of old articles and found a link pertaining to the first posts in this thread. Please bear with me as I am new but I believe this link I found is rather important.

If you look at the little folder icon that has the navigation to where you are . . . for example in that link it says, "60DegreeV6.com>Site Related>Site Articles". However if you go to the homepage and then to the Site Related page there is absolutely no way to get to the site articles from there!

It has been extremely difficult finding some key things needed for my swap. I was going to buy an engine months ago but every day I'm finding new things that alter my decision. After finding the Site Articles I have much more confidence that my swap will be a success. I implore anyone who can make changes here to add the link to the Site Articles in the Site Related section! A big thanks to everyone who has contributed to this site!

your the man buddy....thanks

Today I was looking for 96-98 upper and lower intakes, and I couldnt find them for under 75 bucks each! bullshit man! I can get 3400 cylinder heads for 75 each...wtf!?!

anyways, i was at the shop today, and I decided to take of my intake again and just go bananas on the upper plenum and the openings of the lower runners...
I took a motherload of metal out of the upper plenum... the neck area I shaved down and contoured the egr hole and pcv inlet hole, kinda hard to explain, but I got in real deep and shaved it.
each of the ports of course first got a heavy grinding, followed by a round sanding ball that kind of complimented the curves... I shaved that bitch SO much i was standing in a pile of metal... what fun. didnt comprimise the plenum though.
Anyways, its no 3400 swap, but the difference is noticeable... I have some pictures if any body wants to see, some before and afters of lowering the car, and other shit.
