New w-body owner here. I've got a 1995 Monte Carlo Z34 I picked up at the auction a few weeks ago for $450 and I was going to do some minor cosmetic work to it and resell it but now that I've driven it a little I'm just going to keep it. I'll get some pics of it up soon. It's a really clean one owner car that was traded in on a new car and the dealership took it to auction due to the miles and year. I'm here looking for some performance tips on these cars and just to get some more general info on them as well. This is the first car and FWD vehicle I've ever liked driving. I own nothing else but trucks and a car really doesn't serve any purpose for me as I can't haul anything in in(except a$$). So far I've replaced the headlight housings with new ones along with 7100k bulbs and fabbed up a CAI behind the front bumper. I think next I'm going to do a cat and resonator delete but keep the stock mufflers.

Welcome! Things seem to be kinda dead around here for the past day or two...

Welcome to the forum.

YOu mentioned a cat delete... Not sure how loud you live your vehicles, but I did a cat delete on my Lumina, and upgraded the whole exhaust system to 2.5" along with a Flowmaster 40 series muffler and it sounds awesome

[marvilusone]

I normally like loud pipes but I'll be using the Monte for road trips and I'd like to keep the tone to a reasonable level. My Chevy 1500 has full straight pipes as well as my Powerstroke diesel. I'm hoping to free up some flow on the Monte and add a little tone with the cat and resonator delete. I'm looking to get the B&M Shift Plus controller for it since I have it on my 1500 and I've been pleased with the results. I'm also looking for info on some higher ratio rockers or possibly cams to free up some more power. I've been trying to do some research but I haven't been able to find much. A big bore TB and MAF would also be nice.

i just did a whole down pipe back replacement, replaced cat with resonator, just one. then two magnaflow mufflers, and some nice rounded rectangle tips with a smaller circle hole in the middle that just fit the cut outs in the bumper.
got it done relatively cheap, i have a vid, let me know. i can also help you out with the power thing too.

one easy quick way is timing. i bet your engine explodes with power right around the 3,500rpm mark?

[Mike]

I'm kinda curious about mine myself. It seems like most of my 3100's power is all in the low RPMs

[SofaKingWeToddDid]

those supercharged motors are good, but more of a good base. i would get a blower pully delete kit with block off plate, and turbo that shit!! the kits are relatively affordable and you get alot of power off of 10lbs of boost. intercooler included! lol

is a 95 MC Z34 a 3.4DOHC or did those get the 3800?

[Mike]

the Monte didn't get the 3800 until '98, before that it was either the LQ1 or 3100

[SofaKingWeToddDid]

good to know... his probably isnt new enough to have the separate TB then, right?? his would be built into the UIM like mine, cuz i think the one with the runner is like 97...?

[Mike]

'96 according to wikipedia. Theres a difference of 5 horsepower gained between '95 and '96 on the LQ1, and I would assume it had something to do with changes made with the TB and god knows what else.

[SofaKingWeToddDid]

electronics, OBD1 to OBD2 maybe...  plus the UIM and LIM were different, the TB on the older ones CANT be removed -easily. and the newer ones you can drop almost as big of one as you want on there... being of course limited to the tube size

I'd like to know some more about gaining some more ponies. Also mine is the 3400 DOHC and yes it is sluggish on the bottom and right around 3500rpms it takes off. I'd like to pick up some power down low for DDing and drivability but power up top it the main concern as I'm going to be using it alot for drag racing at the new Zmax Dragway at Lowes Motor Speedway. It's only 20 min from my house and it's 4 lanes all run at once!!! Test & tunes are fun since you can get in alot of runs in an evening. My 1500 is currently running 13.6's on a 240k mile drivetrain and my Powerstroke is running 15.3's.

[SofaKingWeToddDid]

NOT a 3400, the 3400 is a pushrod engine.

and im gonna assume its auto, cuz i dont think those ones came in 5 spd. -the 5 spd swap would help you out too... and ill look around later tonight or tomorrow for some links, but you can get longer duration cams (opens the valves up longer and at different points) theres a set of Ford fuel injectors that are like 45lbs/hr or something like that (compared to the 15 - 17 you have now) if you know a good machinist you can bore out the TB to get more air in.
a crank scraper helps too, new valves, connecting rods, new copper head gaskets to build up more compression.

and dont mind revving your engine up. they can take it. mine is pretty much the same engine and yeah, next to no power till 3500rpm.

a motor swap might be another thing to concider.

the 3500 top end fits on a 3400 and gets more power than the 3.4 and has more torque too. plus the power starts right at the bottom, not at 3500rpm. lol

now, i just smoked a ton of bong. so that might not make sense... too many numbers for me right now. so if it needs clarification let me know

heres a vid of my exhaust. forgive the wind noise as it was kind of unavoidable...

1.)  Do a 3400 top-swap and you'll gain 15 ponies and a hell of a lot more top end power.  If you're ambitious, go for a 3400 lower and a 3500 upper.  You might have to do a head swap, however.  I think it was mid way through 95 that they changed over to roller rockers.  The older stamped rockers interfere with the 3400 lower intake's runners.  You can't install the roller rockers on the older stamped-rocker heads, so a head swap would be in order.

2.)  You'd want to install a Series II L67.  The Series III is drive-by-wire, and most likely would be difficult to get to work in your car.  People have been swapping Series II L67's into 1G W-Bodies for years now, so all of the "figgerin' out" has been done for you.  Motorswap.org is your friend in that regard...

[SofaKingWeToddDid]

i can agree with that.
