Quad 4

[Mr_Efficiency]

Just curious, I know the Grand prix came with the quad 4 in the early 90's but is it a common combination or no? was thinking if i was to try and find one what I'd have to go through to get one as I have never seen one, but i never really looked either.

also was the quad available with a 5 speed in a w body? and was this a pontiac only thing?

 

[ismellrealbad]

No they were not common and yes they were available 5 spd. You generally dont want a 4 banger in a 3300lb car tho

[Mr_Efficiency]

I was thinking for a race car since i can put a HO quad in it out of my race car and being a race car it would be gutted and hacked up and the entire front end reconstructed out of 1 3/4" roll cage tubing so the weight is up to me, I just want it for the track width over the grand am.

also my track makes me weigh 2828lbs and every other 16v car is 2500 and the 12v and 8v cars are 2200, I still beat them tho, lol

 

If i was to get a v6 GP and put a quad 4 into it, what kind of issues would i run into?

 

Obviously wiring from the quad car, thats no big deal. I know the bell housings are diffrent so i need a quad 4 tranny. my only concern really is the drive shafts, i know for a fact the outer (wheel bearing side) of the drive shaft has a bigger spline than the grand am, but not only that the GP is a good 6" wider than the GA. if thats the only issue tho I could always buy them new.

 

Also anyone know if the quad in a W uses the front and rear mounts or the stupid mount on the front (timing cover side) of the motor that connects to the passenger side frame rail. I know all the quads in N and L bodies are mounted using the front and rear mounts until about 92 then they used the annoying frame rail mount that goes through the center of the pulley system and makes doing anything around the front of the motor a PITA.

thanks

the HO quad 4s that came with the 5spd in the Cutlasses have enough zip behind them.....they are a lot quicker and more fun to drive then the 2.8, 3.1 or the 3100 w-bodies are...

[93cutty]

You won't find many quad 4's because they had a bad problem blowing head gaskets. My buddy had an 89 grand am with a quad 4 and that sucker would smoke my 5.0 firebird.

[Crazy K]

*wants an HO Q4 5 speed*

[ismellrealbad]

yeah 5spd i guess they wouldnt be bad. ive never driven one. i just assume i wouldnt need to use my imagination tho

Your talking to the wrong person, I have 3 HO quads and one LO quad in my garage rite now plus the HO in my race car. I can find plenty of them, and only one has a blown headgasket which is no big deal to me at all cause i rebuild them for the race car anyways no matter how good of shape there in, i like to start with a fresh motor.

 

I'm not nessisarily looking for a HO motor I just want a grand prix with a quad so its an easier starting point when i swap it over to an HO, I was un aware they came in the cutlass supreme.

I thought the W only got the LO quad. and since the W got the HO that also answers my 5 speed question cause the HO was always 5 speed, you will not find a stock HO auto.

 

Did the grand prix ever get the HO tho? or just the LO, I like to stick with my pontiac's

 

[jeremy]

GP = LO Quad only

 

Cutlass = LO & HO available

 

Lumina/Regals obviously never got them.

 

Quad 4s are a LOT of fun, most people who bash them have never driven one

[19Cutlass94]

I would imagine with a 5spd behind it, it would be pretty fun, but the older cutlass's ( pre '93 ) where the old design and were lighter than the 3100 cutlass's

[Mr_Efficiency]

I always thought the v6 was better in a W body cause of the torque. the Quad has lots of power but only 160ft/lbs of torque so i'd think getting a huge car going the v6 is better but up top the quad would kill it.

the pushrod V6s were rated only slightly higher ft/lbs torque then that

[GOT2B GM]

Did someone say Quad 4 ?

 

[Mr_Efficiency]

really? i always thought the 3100 and 3400 would be higher up there.

 

anyways, can anyone answer my driveshaft questions above?

 

[Monkton]

Great engine when it works, not so much when it doesn't. I always thought mine had a decent amount of power, especially for the LO.

 

Yeah, the 3.1s were rated around 180ft/lbs and 215/220 for the 3.4.

You'd need to find axles from a 5 spd w-body for them to work.

[Mr_Efficiency]

oh yeah, duh had a brain block there for some reason i thought i could only use quad 4 specific driveshafts, but yeh i guess any 5 speed W body driveshaft would work. hmmm this is starting to look like a possibility.

 

I love my GA but i'm thinking of building a second car for next year to run at a different track, run one friday and the other saturday. they are two very diffrent tracks and at one they inspect the cars and at the other one they dont and its pretty much a run what you brung.

Let me guess...they inspect at Kawartha and don't at Peterborough?

 

Kawartha is a FAST track....it's too bad there isn't more passing there tho.....If you run at Kawartha this year, I'll probably see you there racing at some point over the summer....we always make a trip or two there in the summer...Peterborough not so much..I find it too small too many accidents for the Late model or SLM shows......

Every think of making the trip down to Capital City in Ottawa???

remove Q4 and install TIII

 

j/k

 

only way i could deal with the Quad-4 is if it had low compression forged pistons and a T3/T04E shoving air into it.

Why just because you are a turbo guy? They are pretty quick stock 180hp for ho trim And they will out run most 6 60's My dream quad would be a sprayed ho in a retta!

well....yes. why else? a Turbo Quad-4 would kick ass! that engine deserves a turbo. GM should have at least made a detuned version of the '88 Cutlass Supreme Pace Car engine available instead of just high compression and more aggresive cams. i agree they are quick for stock but jeez...just try to make one faster without a power adder. you won't gain that much relatively speaking.

 

and spray is for wussies

That post scared the sh*t out of me, lol how stalkerish of you

 

yeh i'm going to run Kawartha friday nights and peterborough saturdays, but you have it backwards, peterborough will tear down motors and kawartha even told my class they are not going to inspect us... they check every other class tho.

I've run kawartha a few times but i need a cheater car to keep up, I did pretty decent tho but i need something more to even touch the fast cars.

 

My friend ran both tracks with the same car but he ended up striping the cam tower bolts from changing the cam every week to be stock again for peterborough. it was the purple 82 car, he lead the points all the way until the final night.

I run kawartha ocasionally, I was there twice this year and got wrecked twice... yet i can run peterborough without a single problem, just bumping and rubing.... you know, racing, lol

 

were are you from bake82? did you ever think of comming down for the autum colors weekend at peterborough, thats a race we had over 60 cars in my class alone, I won my heat and qualified 6th.

One thing i still can't get over with the Quad 4 HO motor is how much hp and tq it was making waaaay back then. Compared to the new k20(IIRC) out of a new Civic SI, they are only making 197hp and something like 130ish tq!!!

 

17 yr old technology

Quad 4 HO

180hp

160tq

 

State of the art Honda DOHC 4

197hp

130ish-tq
