Some Header Help Pleaseeee! Want some opinions on my car as well!

Anyone out there know of a header that can give me more a lil more flow than the stock header.
I own a 97 SC1 with a bored throtle body, custom built ractive cold air intake, ractive 2.25 inch cat back exhaust with a ractive muffler, gutted rear end, bosch +4 plats with delco wires(they gotta go), and short shifter. It's runnig me 16.11's on the 1/4 mile on sticky street tires and a 2x12" sub setup..I've been told to do the following to shave a couple seconds off my 1/4 mile time: NOLOGY Hot wires, NGK plugs, MSD ignition coil and Ignition, Change the ractive intake to an AEM, Honned intake manifold, find a decent header, port and polish the cylinder head, redo the cam, magna flow cat, venom chip, and a dual exhaust. 100 shot NOS.
$$$$3300$$$$ approx in cdn.They figure from 110 HP to close to 200 with out NOS..and some where in the 14's. 13's with the 100 shot.
I wanna know what you people think any advice is appreciated.. i know you got some opinions sierra...lol..lets hear em!

are you going to make this car primarilly a racer or keep it a daily driver?

this the only header for the SOHC to the best of my knowage.

first, pull out the sub at the strip ;)

second, don't get the NOGOLYs, they wreak havok on the car's electrical system. maybe use them if you use the car purely off-road, otherwise you are asking for trouble.

you also may want to get a 0.5 mF or 1 farad cap if you don't already have one (depending on the size of the stereo)

i don't know much about venom, but many high perf saturn owners go with megasquirt - http://www.turbosaturns.net/forum/viewtopic.php?t=1922 or APEXi - http://www.saturnspeed.com/super_afc.htm

also, i will be highly surprized if dual muffiers will help any, more likey your backpressure will drop to low.

and lastly - 16.11? on a N/A SOHC? can you prove that with a time slip?

as soon as i get a hold of a scanner i'll post my time slip also if your wondering which tires i used they are yokohama advan 32R's there barely street legal.. but thanks for the info.. what i want is basically a quick street car not a race car and definately not just a daily driver,, so what would you recomend in ters of plug wires?? is magnecore any better or just the same? also.. i thought they discontinued the hot shot because the flanges were to thin...? any ways thanx for the help by the way what kind of car do you have sierra?

forgot to post the numbers..
r/t-.568
60-2.21
330-6.47
1/8-10.17
1/8 MPH- 66.871
1000-13.37
1/4-16.11
1/4mph-16.11

Wow. you must be the mack daddy on your block. anyway, I wouldn't change the intake. ractive has very good products plus their exhaust stuff tends to be a little quieter than others. Maybe put your satty on a dyno and see how much increase power there is. The good thing about AEM is you can add their great bypass valve in case the filter gets wet. I would say get an Injen short ram and build a cold air extension since injen tends to produce more power on the dyno than aem. Definitely get the mainifold honned or buy the SPS one, you will get more power. Cylinder heads will add more serious horses too, but I don't know what your budget is. Dual exhaust isn't necessary unless you want to show it off. NOS would be sweet in a saturn! Make your car fun to drive by any means and, in my mind, making it fun is making it fast.

You can always look for the stock headers from a 91-92 sl2, they are reportedly as good as any aftermarket headers, and way cheaper if you can find them. They might not be compatable with the SC1 because they have different heads, but they are very similar engines and I would not be surprised if they fit.
also I totaly agree with forgeting about the dual exhaust, for a 4 cylinder car a 4 into 1 into 2 setup (which is what I am guessing you are going to do) doesn't have the advantages you normaly get from something like a dual exhaust camero with a 8 into 2 setup (this prevents interferince in the exhaust pulses), but it would be hard to fit a dual exhaust into a saturn. you don't need such a high flow exhaust, exhause systems are not about just getting the lowest backpressure, they are about getting the right amount of backpressure.

Also don't forget to lighten that thing as much as possible, removing weight helps everything, not only will it be faster, but it will handle better, break better, and your tires will last longer

as soon as i get a hold of a scanner i'll post my time slip

so what would you recomend in ters of plug wires?? is magnecore any better or just the same?

i haven't played around with wires like some have-
http://www.turbosaturns.net/forum/viewtopic.php?t=14426
some say MSD, some say magnecore, even some say autozone...research is the key

i thought they discontinued the hot shot because the flanges were to thin...?

although i don't know for a fact, i heard that that was only the DOHC headers and they were redesigned because of it. contact hotshot to confirm.

by the way what kind of car do you have sierra?

1994 SL2 Manual trans, ABS, Cali emissions, 168K miles, currently parked awaiting a rebiuld

they won't DOHC and SOHC exhaust flanges have different bolt patterns, but if nothing else works, i wonder if the DOHC header could be welded to a SOHC flange?

but it would be hard to fit a dual exhaust into a saturn.

i've seen it done, hard but not impossible, i won't do it to a lowered car though. hell the 93-95 SL2 rear bumber almost looks like it was designed for a dual muffler.

they are about getting the right amount of backpressure.

bingo. backpressure = lowend torque


also, with all this engine work, i assume you are also considering brake and handling upgrades?

yeah definately i gotta get bigger rims first though.. its kinda hard doing a big brake upgrade on a 15 inch rim lol..umm what about the header off of a 91-92 sl1? would the holes on the flanges match up with the head on my car? i just got my ngk plugs im awaiting the wires. Also, the dealership says as long as the exhaust tubing is small i shouldnt lose any back pressure..meaning i would have to change the existing line and go back to stock..which i really dont wanna do...for handling though.. what are your suggestions...? go with sps stuff or go like h&r or eibach? lemme know..
thanx for all the help off to do some resaerch!

Although i don't like springs personally, I would go with either eibach or sprint for springs. SPS has braces and sway bars as well. SPS also has good suspension packages too, probably your best buy for upgrading suspension components. Definitely upgrade the rims. I believe you need a 16 to 17 inch rim for brake clearance when upgrading with a big brake kit, plus get some light ones as well to take off some weight.

anybody got any opinions on 18" rims or are they just a waste of time..i got offered some 18x7.5 for 950 cdn..with some racing rubber mind you..i dont know how much those will slow me down but the look really insane!

18" rims might be too big from a performace point of view, realy low profile tires may look cool, but they don't flex properly and they don't handle as well (again it's about ballance so do some research). Plus if you live anywhere you get frost heaves then you will ruin a rim a year or more on bumps.

Also I don't think the 91-92 SOHC had headers, just the same manifolds, I may be wrong though.

i kinda wanna keep my 15's and im guessing the only way to increase the breaking power to to get slotted and drilled rotors or to do a 4 disc conversion. did any of the past sc come with 4 disc does anyone know?

any sc2 with ABS has 4 disk breaks, sps also sells a rear break conversion kit

car might be sold soon.. having a few problems with it and the k's getting pretty high not really worth all the money and then performance mods on top of it just wanna say thanks to everyone for your help in the last few weeks the way things look now im getting a honda out of this deal i know its kinda moving down from what i already started but i dont really have a choice :(

problems??? details please

where to start..broken motor mount, sloppy ball joints, bent lower control arm, a lot of paint issues, probably gonna need a new water pump and timing chain, drive belt, umm cant really think of anything else right now.. you think it might be worth fixing? i know that the lower control arms cost 85 a piece, that includes the ball joints in that assembly, no clue on a motor mount, umm paint trying to get my neighbour to touvh it up, drive belt is 25 bucks, water pump and timing chain no clue...on top of performance stuff..plus i got about 4 sets of tires for it.. kinda be a waste not to use them. and considering i just spent 100+tax on ac delco rapid fire plugs and magnecore wires.. but im still not sure lemme know what you think sierra it seems you know your stuff so gimme some help thanks

mount(depenting on which one)45-80
waterpump- 35
timing chain - 200

parts only not including labor

and i want to say i've seen cheaper LCA somewhere, try autozone, or search on saturnfans.com

should you do it? to quote your bio - Love my car!

good point.. now are those prices canadian or american....200 is pretty damn expensive for a timing chain...the last car i had came out to 200 and that was including the labour? and you never heard of gapping the performance plaugs at 0.045? it says so right on the package?? thats weird..

american, what was your other car? i belt it was a belt not a chain, that price is really for a kit that includes the sprockets, guides, chain, and tenitioner

1988 chrysler lebaron gts 2.5L 4 cylinder.. i wish i kept that car to drive in winter but i had no room to keep it :(
