V6 to LT1 Swap ?'s

[93formulalt1]

I think you all missed my point. . . My mom's 95 Olds is just about dead now as far as the body goes. It is a 3.1 Liter FWD. Can I take any parts off of that motor and put them onto the 3.4 in my camaro? I don't want to rebuild the 3.1 or anything, because it sucks. I would rather just build up my 3.4. The reference to the Buick GN was just to show that a V6 can actually run a 9 sec. 1/4 mile. I know they are totally diff. My camaro has a 3.4 rwd engine, not a 3.1. Just to clarify.

i know that... what i was saying is... the 2.8 3.1 3.4 all the same engine... same block just different bore and some a differnt stroke... but the block is the same.. if you take your 3.1 and bore it out it will in turn become a 3.4 thats how they make the 3.4... so if the block will bolt up to the rwd which im still not posative on yet... then yes you can use the 3.1 parts the only thing different is the acctual piston size... and probably the program running the engine.. so if it bolts up if... you can rebuild the 3.1 to a 3.4 same cast number and everything if its the same block... get the stroker kit have the heads rebuilt if they are the same as the 3.1 which if its a 95 and yours is a 94 they might be the same... then all the sensors and from the intake up off your car now just toss on the newly rebuilt 3.4 stroker and go...but you have to find out for sure if its got the same bolt pattern as the rwd version ive checked a few places no luck... might just have to call up a dealership... but if it does that would be a cheep easy way to fix it... you can drive what you have now while you build up a new motor then eaither drive yours till its dead or spend one maybe 2 days tops putting the brand new motor in...

Do the heads and intake on the 3.1 olds engine flow any better than the ones on the 3.4? Those would be a relatively simple swap, and it could ptentially add some power. More airflow=More Power, so I am looking into a CAI for my car. Thanks for your advice so far, and I hope we can come up with a decent plan for my build soon!

Dunno about the 3.4 but my 3.1 '94 cutlass has aluminum heads, which are a benefit in and of themselves. Seems to me like one of the articles meissen posted about the 3.4 motor said that the 3.1 head flows as much as a ported 3.4 head. Might want to look into it.

[wezeles]

what year did they make the 60-degree blocks into factory rollers? i know that made a huge differance in preformance too.. frees up something like 45 hp...

[wezeles]

alright did a little research for ya... and yes all the internals are the same but the bolt pattern is different for the trans... basically the 3.1 you have is just a slimmed down version of your 3.4 same crank and everything just different bore... but yes if thats got alum heads... use them the flow better and weigh less... so if they are aluminum or even if they are the cast its the saem as what you haev now... you can take them off get them cleaned up and rebuilt then your all set on that end... im still tryign to find the stroker kit... so far comming across just short blocks and long blocks with the kit in it... not just the kit itself...

I remember the post that meissen left about the V6 performance. I know that one of the intake and heads options was the parts from the Olds 3.4 FWD engine. The intake flows better and everything, so I'm going to look around all of the junkyards for a newer 3.4 alero or something and buy the heads and intake out of it. Is $100 too optimistic, or should I expect to pay more? I want to have a sweet V6 camaro. My brother in law is getting a little cocky about the performance of his 3800 V6 in his grand prix, so I at least want to whoop his ass on the strip. That's what I hope for, but I will settle for just about anything now. What HP/Torque should I shoot for?

[wezeles]

depending on what parts you get i think somewhere in the 250 range wouldnt be that far of a reach.... specially if you rebuild it and hit it with some no2 they have pretty low compression stock like 9.1 i think but thats just about perfect for no2... not to low that it doesnt effect it and not to high that your going to detonate... i would say find a 75 maybe 100 shot that would make a huge differance... maybe some bigger injectors, you can get the after market coil packs pretty cheep... new wires and plugs... headers and exhaust if you dont already have it... once you let that engine breath you notice it... i tossed a K&N CAI on my grand prix with flow mater split twin exhaust... that alone made that car sound and feel that much meaner... if you cant find the 3.4 parts off a fwd let me know i know i have an intake and maybe heads at my mech garage i dont think anyone really needs them or even owns them for that matter.... its off like a 99 alero...

[93formulalt1]

How much you want for em? I don't have much, but I can see what I can scrape together. I just bought the car, and the only mods I noticed were the paint job and a glasspack. No dual exhaust or headers, just a glasspack. The car already goes like hell, I have a reliable source that says the car will hit the programmed speed limiter with no problems. *winkwink*
I'll definitely take the heads and intake if you dont want too much for them. I just wanted to be sure that these parts won't cause any unwanted effects, like a blown motor. If the comp. ratio stays about the same, I should be in good shape, right?

i have a set of heads in the garage off my 3.4l Firebird that you could take of fmy hands for cheap. just get them PnP and cleaned up they will perform,
then i would suggest calling comp about a custom grind cam for the engine.

get a new intake uppwer and lower get them ported to match the heads
Go with a custom cold air intake, i could do that for you. i could drive on the way my engine would be at 130-140 degrees the whole time. the block woudl be hot the intake manifolds were always ICE cold. i built my intake right. Also clean and PnP the throttle boddy it tends to get oil coated on it along with dirt from the PCV hookup into the elbow.
if you get the 3.4L to breath right it will run strong bevieve me. i had the stock trans an di could squack into second i just got mine to breath right,
i had 130k miles the only thing wrong with my engine was a cracked tensioner pulley, and a bad EGR valve.

if u want help deciding just PM me. in the spring we can do a custom full cold air intake foryour camaro. but decide which manifolds ur going to go with for the intake, i would also suggest doing the cam and heads over the winter along with the intake. and lifters.

[wezeles]

well if your going to put new heads on you should atleast clean up the bottom end... in my experiance whenever you rebuild half of the motor the other half dies quickly after... but that would be cheep say just hone the block... gets some new rings and bearings and clean up your pistons now... maybe cost 150 bucks for parts... if that then put the new heads and intake on... ill ask him next time i stop by to work on my motor... im sure he wouldnt want to much for it... if not im sure i can fond another set to hook you up with cheep...

Wasjo6431, I am trying to get better flowing heads than the ones on the 3.4 RWD, but thanks for helping. Wezeles, my dad says I would need what you mentioned and an oil pump, but I can't imagine it costing much more than that. I don't really know how to do any of that, so I'm going to talk it over with dad. I don't have any money, but I'm going to get a job soon. Then the mods will start getting serious.

[93formulalt1]

wasjo6431, I would really appreciate help with a cold air intake. The engine in my camaro is all stock right now, and I know how much a CAI helps. I put one on my 4.3 H.O. Blazer, and it ran like a champ. I'm going to clean up the throttle body tomorrow, don't know about P&P. Is that something I could do myself, or would I need to take it somewhere? I can't do anything else over the winter, college classes just started back up, and I need books. You know how that is. Thanks for your help, and I hope to hear from you soon!

[MattODoom]

Yeah whenever you have an engine apart you should always replace the oil pump.

Cheap insurance.

Youll need a complete gasket set too, that kinda stuff.

[93formulalt1]

Do you have any idea about a rough price range?
