Intake Swap on a 3.4 DOHC???

[GrandAmSE]

I was wondering if you could put the upper and lower intake from a 3400 HO on a 3.4 DOHC? I hate the 3.4 intake. Both engine are 60* engine but is the valley space the same? Is there even any intake swaps possible for the 3.4?

[firefighter_0029]

You can get one from a 96 or 97 and have to take the top intake off to change the spark plugs.

I like the 6 hour tune up.

[digitaloutsider]

What are you talking about? It takes me about 5 minutes TOPS to get the plenum off.

DOHC 96 or 96 /\ but no, there are no other swaps like that

The 3400 is not HO, Pontiac states it HO because it has that stupid Ram Air setup.

 

The 3400 is a pushrod, not a OHC engine, so there IS NO WAY TO PUT IT ON. Not to mention if you could I don't even know if those flow that much better.

 

The only swap is the 96-97 UIM and LIM, or make a custom one. There is a write up on 60 Degree to do the swap.

What is that what the dealer charges?

Do you even know how to change plugs on a 3.4

 

You only have to remove the UIM, which is like 10 bolts, not the whole thing.

 

Next time when you come to the yard, I'll time you for removing the spark plug out of a car, cuz you couldn't manage that at all.

FYI all those engines have been exposed to the elements for awhile. Those plugs were stuck in the block. I got the ones out that I could.

 

I wonder how the tune-up on my car got done Tony. I must have just opened the hood and the magic AC Delco fairy put on my plugs, wires, pcv.

Edit: I'm not going to ruin his thread.

[Regal_GS_1989]

You dont really even need to remove the UIM to get the change the plugs on a 3.4. You just need a long enough extension and a spark plug socket. 10 minute job at the max to change the plugs.

On the 96's you do. The runners sit against the firewall.

[GrandAmSE]

Whats the difference between the 94 intake and a 96/97?

[Z34-5speed]

On the newer ones the throttle body is not attached to the manifold, you can remove it.

It's supposed to flow better overall. I haven't seen any dyno sheets to prove it. I've got the '96+ intake on my car, and with no other mods but a gutted cat, FFP chip, and short ram, it ran a 14.8 in the 1/4 mile, which is a damn good time for a very minimally modded 5-speed LQ1.

[99RegalGS]

What are you talking about? It takes me about 5 minutes TOPS to get the plenum off.

No kidding!!! I'd rather do plugs on that engine then ANY other OHV 60*!!!! I can probably do them quicker also. Now the 91-95 plenum is another thing....

 

 

And yes, the 96,97 intake helps top end power A LOT!!!! If I ever own an LQ1 again I WILL swap the 96,97 intake onto it.

[Baddflash]

Is anything lost by swapping to the newer intake, ie bottom end power?

 

I would love the idea of being able to remove the TB, plus I feel this intake doesn't allow the motor to work at it's best.

 

I have the perfect intake (1st gen SHO ) to swap, but it would require so much to make it work including a new hood with a massive scoop for clearance, custom intake adapter, custom circuit to operate the secondaries. I would love to see how this engine would react and sound with the Yamaha 2 stage intake. I'm sure you'd see a big improvement across the entire powerband.

Umm, well Ben recommends the 96 intake for manuals instead of autos since the manuals will go to 7k.

 

Even the 96 intakes aren't that great. The only intake that would be well suited is a custom one.

[BandaorICE]

hmmm, some how with a little ease and care i can change plugs without even taking off the plenum...15min spark plug change...once a month.

I'm going to ask a newbie/retard question..............

 

Has ANYBODY hooked a 96/97 intake swapped LQ1 up to a wideband O2 sensor OR done ANY kind of research into what the gains are?

 

You see, I HAVE a 96 Monte Z34 TB/TB arm/UIM/LIM combo sitting in my garage (and it already has the injectors in it for other reasons)................

 

Mine IS a 5 speed, but I have been holding off on swapping this stuff over for 2 reasons

 

A ) I'm fat and lazy.

 

B ) I actually want some PROOF that this is wirth a shit.............and I AM looking at getting one of Ben's chips here shortly, because I HATE governors, but I DO like the idea of getting some power as well...........but his site states that his chips are NOT set up for the 96+ stuff...........etc etc etc.

 

Basically, I just want someone to hold my hand and say "do it....it's ok"

[dohcfiend]

i agree with 5speedz34. the 96-97 intakes are ok and can be modified but a completely different or custom intake would be best. i remember and article a long time ago where a guy basically put a sheetmetal box and a tb on a 91-93 LIM on a lq1 and dynoed 240hp to the wheels. keep in mind it wasn't very streetable and had little low end but a dual runner design like the sho intake would kick ass b/c you'd net some nice hp without sacrificing low end.

 

on the new vs old. the older ones are better for low end and u can change the plugs without pulling the plenum. the newer ones get more high end and have removable throttlebodies. all depends on what u want out of it.

Like I said (and Ben said this also) I would only use the 96 intakes on a manual since they rev higher.

I don't think anyone is running a wideband o2 with the 96 intakes but I could be wrong.

 

I have Ben's chip with 96 intakes though, so I don't know where you heard that.

[BIGBULS]

Ok.............."not been tested yet for tuning"..............lets put it that way

 

http://60degreev6.com/store/index.php?act=viewProd&productId=6

 

In any event, *I* want more than a little 'butt-dyno' proof...........call me sceptical (sp?), call me fat, call me what you will, but there you have it.

 

Wideband O2 would give you an idea if the "base" tuning works ok..........it isn't a dyno, but it's SOMETHING.

 

How about track times (or more importantly...trap speeds)?

 

Don't get me worng, asshole that he is (on occaision), Mr. Ben Phelps CAN program the shit out of a chip for a FWD GM car, but I just want to get the most power per $$ that I can since my piece of shit already has 137K on it (41K of it MY seperate form of abuse)............

 

 

 

Put it this way: with my NX project temporarily on hold, I just want to make my daily sack of crap "fun"..............that means more power since it handles like a turd compared to the other two cars I drive (that still isn't bad in the grand scheme of things, but there you have it)....................and you know what they say about "power corrupts"

 

 

Plus, I WANT a 140mph Grand Prix.............124mph (GPS verified) is NOT cutting it (where it cuts now), and I'm NOT certain it has the power even without a governor to hit 140 without a tailwind or a hill helping it out........I guess I'm just biased that way

 

 

MORE POWER FTW !!!

 

[mfewtrail]

I think Shaun's(digitaloutsider) 95mph trap speeds in his 5spd/DOHC Cutlass show that the intake swap is worthwhile. I believe he had the intake swap, catback, and Ben's chip at the time(?).
