i did the 3.4 swap....and i want to know how i can get 40 more hp? i want to get around 200 hp....i was thinking about dynamax exhaust system w/ high flow cat.....some sort of ram air set up...w/ k&n's of course...i'm sure i would have to do more...but give me your guys suggestions...i want some easy mods...also my ac doesn't work....should i go ahead and eliminate that part of the belt? to have less weight? or would that mess somethings up? thanks

Well your on the right track. I think RK sports makes a lot of parts for the 3.4 so I would check with them. They might even have headers, and seeing how the thirdgen under carraige is almost Identical to the 4th gnes most stuff will work, but like I said talk with them and tell them what you have.
TO find the 40 HP you could always port the hell out of the intake and have your heads ported, polished, and dech them a few .001 to up compression. Ofcourse this will mean 93 or 94 octan gas all the time, but hey we want performance right. Also get a full ignition set up to burn everything quickly and efficently. Underdrives seemed to help my Brothers 95 3.4 a litte.
Removing you A/C though is a personal opinion and you will get many of them on it. All I can say is this, if you dont plan on using it there is no reason to fix it, and if its broke remove it. THough if you ever plan on selling the car I would leave it on there. It will maybe free up 5hp in the upper RPMs, but it also removes about 50LBS from the front of the car if you do a complete removal. THis means every piece and hose, plus removing the Firewall cover and replacing it with one from a car with no A/C
Good Luck!

I've pulled my a/c for two reasons... one, I barely used it, and two, the evaporator (piece against the firewall) was crushed in my accident. I took out the compressor, condensor (in front of radiator), accumulator, and all hoses/lines. I put the heater/evaporator box from my parts car on the firewall, with the parts car's evaporator (just to fill the hole). You could do the same; pull the big stuff and put it in your garage. That's where my stuff is, if I ever need to/want to put a/c back in, I have the parts.

thanks guys....well i think i'm going to pull out all of my a/c stuff...how good is accel ignition stuff? i know 40 hp is a lot of horsepower...but i wanta give my buddys tuned out 305 a good run for his money..and those damn rustangs...i think if i got aroun 200...i could maybe throw on a 35-50 shot and do pretty good....i checked out that Rk sports web page,,,and i found a k&n set up,,,but i don't think it will work b/c i do'nt have the 3.4 intake... thanks

Wicked ,
I have heard nothing bad about accel ignition caps.Everytime I have heard of one mentioned , people talk about how they can't get but 6k miles out of them .As for as the ignition boxes and wires and coils I dont know. I have heard crane fireball coil is real good , it is like $50....Maybe some kinda ramair setup would help to .I sawed big holes in my airbox and dropped k&ns in WOW what a BIG difference ,Its automatic ramair on the third gen if you dont have the foglights in the grill b/c the louvers tilt upwards pushing the air towards k&ns.Jet chips or superchips make good chips 10-28 hp.Stay away from hypertech I've even heard someone call them hypercrap lol.Goodluck Wicked ...keep us informed . Wayne .....88 rs new 2.8 V6 mildly modded , getting headers in nov !!!

 

Your not from around here are you?
Dud no chip unless its a custom burn will yield those results.

Well...i'll prolly never sell this car...for two reasons....i'll never get the money back i have put into it,,,and it's just so fun to drive...I'm against chips...personally i don't them..
thanks

Kyle ,
I dont know where your from .But I can tell you I dont like your smartass attitude. Chips are made to work with other mods ,They will give you that hp if use it with other mods , You can't just put a chip on and expect 10 hp ..I have serveral friends which use jetchips and superchips ,They noticed a difference .On my friends camaro with the jetchip , it dynoed at 12.5 extra hp

 

Who has a mass marketed chip they would like to BAck for gaining the 10-20hp increase they claim? Anyone???

I know you said easy mods, but how about a set of roller rockers... Just a thought, they would be an upscale easy mod.

 

Roller rockers FIT, but, not under the valve covers.
The 3.4 is one pwerful little engine.
Get geards, 3:42 & above, now and see how ya like em.

wicked

 

KED85, what valve covers do you use if you want to get roller rockers and where do you get the roller rockers for a V6.

 

I see nobody wanted to back any chips

Go look at Hovrbord98 and OVRCLCK350 post ,chips are strongly backed

wayne

 

Strongly suggested, but notice the CUSTOM one was number 1.....there's a reason.

 

BTW Wayne....um, how are you getting headers?

 

Yeah I know the custom ones are better OVRCLICK350....My point is just jetchip , fastchip, superchip are good chips .I just dont like people telling me they dont do any good when I have seen one dynoed and heard of great results off of others.I have seen a 12.5 increase in hp on a car dynoed .Just because a chip may not do any good for one person in their car , does not mean it does good on others (this last sentence is not directed at you ).....Anyway , I don't know where Im going to get those headers , I hate to order them offline and ship them and have to pay more for shipping , but I may have to . There is a parts store down the street ,I know the manager , he almost ordered me some accel arleady made 8mm wires for my car for only $20.00 but I had to have the wires that day . Anyway so he may cut me a deal on some headers ....Wayne

 

If I cant get them at the parts store ,where do you suggest ?

 

Hey Wayne, I think what Ovrclck is getting at is the fact there are no real headers for a 2.8 bud. Good luck tho. ;-)

 

3.4 headers work

 

"Letter on headers from TOM P "
Hey all, I've got the 2.8 V6 in my car, and it has the EGR valve mounted to the passenger-side exhaust manifold. It's not mounted to my intake manifold. If I buy the 3.4 V6 (93-94 f-body) headers for my car, they don't have a spot for the EGR.
Has anyone made a mount for the EGR on non-emissions headers? I'm not sure where to tap it in! Looks like making the base for the EGR valve is straightforward... a plate of steel welded to a tube. But- where should I have it suck the exhaust from? I see three options:

1. Have the EGR get the exhaust from one of the primaries
2. Bend/weld a tube all the way from the EGR spot to the passenger side collector
3. Build an AIR-type manifold, so the EGR takes from all three (V6!) of the passenger side primary tubes

Has anyone done this? Any thoughts? [edit] Oh, and yeah, I can weld... not like a pro yet, tho!

crap , cant get the link to go on here ..scroll down

 

above link does work

 

"Letter from archives "
Tom, the 3.4 headers DO have an EGR hook up on the passenger side. I have them on my 3.1 and the EGR hooks up perfectly. If your 2.8 is a tad bit different than my 3.1 all you would have to do is extend the EGR tube somehow going into the plenum. The EGR base wher it fits on the exhaust manifold looks like a wide triangle with a large hole in the center and 2 bolt holes on ech side of it. If your EGR base looks like this it should work fine. The only problem is bending the headers and getting the y-pipe made.

Roller tips can work under the stock valve cover
FULL ON ROLLER ROCKER, will not FIT under the stock valve covers.
BUT
BUT
BUT
I believe ther is one person (Graeme) that has this full on roller rocker set up!
NOW
How did I get those tranny bolts loose?
It was with a cool tool
Short wrench with a ratchet in the boxed end.
Does that make sense to ya?
Just kept at it until loose.
I have to admit, I did fail to put back one of those bolts, top middle one. Wasn't worth the effort. Now that the tranny is coming is out, I'll let the tranny guy do it (put that back in).

Full on Roller Rockers are from Crane, only, IF I AM CORRECT.
Graeme may be able to assist better, tho.
I used everything stock. Valve covers, etc!

I'm saving my Comp Cams 1.6 roller tip rockers for my 1974 Corvette engine, with the stock cam. Cheaper than an upgrade of Cams, at the moment.

You did swap to the later style fuel injectors, correct?
If so, toss that comment out to the "chip maker".
I have to let the rest of the members assist you with their knowledge, as I have mine stock and it works well.
