Well since series I performance site is gone im at a loss as to what mods i should do. right as i saved up for rockers and a cam series I site was gone. So i got to thinking what other mods can i do to my engine, however i already have a intake,180 stat, plugs, pulley, pref mufflers w/ no resonator. i was thinking maybe i should work on my exhaust maybe port my headers? downpipe? which i talked to a shop close to me who knows my car pretty well and said to port my headers it would be 300+ dollars. So would it be worth it? or what other mods are out there that i could do? i dont want to swap for a series II because i want everything original in the car. any advice would be great thanks.

I think rocker arms made for Series II engines are the same. You could replace the stockers with aluminum 1.8:1 or 1.9:1 + valve springs. Do some research first, but I think it would work.

There's got to be some way to rig up a 3" downpipe for your engine, too. And Series I pulleys are still out there.

yah i will have to definitely check into the rockers and take my car to down to a shop near me and basically ask what can they do improve my engin e and if the series II rockers will work. however i already have a 2.5 pulley in my car. but im really stuck on what else to do? if theres not much else than i just might forget about it and just be happy as it is and get a set of new rims.

Well, porting your stock exhaust manifolds (don't call them headers) is a labor intensive project, but you can do it yourself with a die grinder and the right bits. I ported a front manifold for my 98 last year, first time for me. Turned out pretty decent, imho. It comes off this summer for a coated Powrlog, but unfortunately won't bolt up to your engine. I'd check around on the boards for someone in the OH area that might be willing to work on a set of stock manifolds for you, should be able to get it done for much less than $300, I'd think. But then I don't know what is needed on the Series I rear manifold. The Series II rear doesn't need as much work as the front.

Theres always weight reduction , and you could port and polish the supercharger too.

Nope Series 1 rockers are different from Series 2 rockers.

thanks guys for the advice, i guess theres not much hope for the series I except for the porting my exhaust manifolds and supercharger. but how much hp should i gain if ported my exhuast and supercharger?

Well if you are serious about wanting to mod a series 1 to its full potential. The I would recommend you look in the www.bonnevilleclub.com and look at the work "willwren" (in search) has done to his 1993 bonneville with a 1995 riv series 1 motor. He run like a 14.2 without nitrous which is pretty good for a series 1. I will warn you that he is kind of an arrogant control freak, but you can use his work as a template for what you may want to do to your series 1 and if you think it is worth it.

Also some guys have been working and gotten an OBDII PCM to run a seires 1 motor and trans. That is great just to have the full power tuning capabilities that the series 2 enjoys.

Evan, whatever you learn about modding the Series I, please let us know. We are still a young site, and don't have all the answers yet, but people like yourself who want to mod are the way we will gain knowledge. There are many Series I folks here who would like very much to know more about modding their engines.

I would encourage all Series I owners who want to mod, to get a scanner or G-tech and experiment with different ideas. If the Bonne guys can run 14s, so can we.

Aaron... Fixed your quote up alien

Rockers are available. Willwren used some Yella Terra's. Most of his work is good, however some is not as good.

Cam would be a custom grind, but why not?
Porting the stock manfolds isn't as necessary as ensuring they aren't cracked and causing KR.
Porting the SC is always good. Because the M62 is spinning faster, there is much more heat than an M90. Reduce the intake air temp wherever possible.
His intercooler could have been done better IMO.

If you really wanna get creative , you could try and see if there is any way to swap a gen 5 m62 from a cobalt SS on. I'm sure it wouldn't be a straight swap , but its possible. I've heard series 1 manifolds aren't all that bad. You could maybe get custom headers made , but i'm sure it'll be costly. , if you know someone who does that kind of thing... And to cause controversy , i'll suggest nitrous.

Having looked at a picture i'd say it wouldnt fit , however the internals might swap out. Like i said it would take some research.
