I was thinking on using the new ZZP power log (http://www.zzperformance.com/grand_prix/products1.php?id=208&catid=110) for my s3 swap. Should I invest in that? Or should I just go for headers? I would like to use a muffler and keep my trunk. Tks
Ok. So why on the rails? I heard stock injectors can support 300hp+. Are the rail an obstructiuon for that but injectors aren't? Tks
Rails do nothing more than look good. .They take a decent looking swap and trun it into a damn good lookin swap...that is if you do the rest of the swap right...

Ebay headers seem like a no brainer to me, even on a stock swap. It gives you some more options for exhaust, and moves the stock outlet away from a fairly tough to work with area.

Stock manifold are much easier to work off then headers IMO>.....I know the PS headers where a pain, TOGs not to bad....

How good are Ebay headers flanges? I don't want leaks. I can modify (weld) if needed but want something that will last. Don't the headers dump too low or require trunk modification? Tks

They cut the trunk. I thought you don't want the trunk cut? By the way, the trunk cut is not as bad as it sounds. Not very much of the trunk is needed to be cut out of the way.
What you may want to do is get the swap in and going, THEN go for the goodies.
Fuel rails- not needed stock works great headers- not needed stock manifolds works very well. I have had good luck with a spintek muffler, small and fits the space well.
do yourself a favor and get a smaller pulley like a 3.4 if you go smaller you will/may need a intercooler.
What is you end goal??

Thanks. I got a 3.6 pulley, N* TB, good CAI and Ryan tune as my main mods. After that I found out next steps get very expensive (rockers, cam, intercooler). So I was thinking if I could benefit a little more with exhaust since is easier to do while engine is out. I do want to keep the trunk. If headers will require trunk cutting I will skip for now. I can cut/modify/weld so I was thinking maybe I could modify a little the rear (trunk side) dump to avoid trunk chop. But then again, if all I will gain is 4-8hp from a header then I would skip the hassle.
The cheaper ones do not say what there made out of, my guess would be mild steel w/ some sort of "ceramic" paint finish. The more expensive ones say there SS, so they will be less prone to rusting...

Camaro manifolds + custom Y-pipe, into stock Fiero exhaust routing (perhaps with larger than stock cat-back exhaust)?
Surprised nobody's mentioned this option yet. The ZZP power log is only for the front side. If you want to route full exhaust in the same way as stock Fiero exhaust routing, I'd go for the Camaro manifolds, or custom headers, and Y-pipe.

I have the cheap obx headers but they are SS and have a nice 3/8 flange. After modifying them because they never fit in the first place, they fit just fine without ever touching the trunk. As shipped you will need to cut the trunk but it really only took me and a buddy a couple hours to chop and modify the headers. I have true dual exhaust but it wouldn't take much to make a traditional one with these headers. Don't get them for a hp gain, get them if you plan to mod the motor in the future to beyond what the stock system will flow before being too restrictive. In other words, if you plan to mod in the future do your exhaust right now so you don't have to redo it in the future.

Are you saying they'd work better than the 3800 S/C version? If so, why? If no, why not? (Again, I'm asking from the standpoint of a humble inquisitive student....)

I took the manifolds off today. I can only say wow! Now I see why the ZZP p-log makes some sense. Anything can be better than that rear manifold (do I need to mention top one?)

I was thinking they weren't as "long" for some reason though. But they are less restrictive than the stock FWD 3800 manifolds. But custom headers are probably the best option. Especially given the pricing for these: http://www.westcoastfiero.c.../3800_series_ii.html
