i would suggest the powerlog from zzp for a n/a

I can port them for you, polishing will give your practically no gain over just a port and smoothing, but thats where a lot of money goes in a port&polish job.

I can gasket match and port out a set of logs for 100 bucks you pay shipping, turnaround time is less than 1 week, if you'd like pics of my work I can get some to you, I've done a lot of porting for turbocharged mitsu'*. exhaust, intake, heads, etc.

The proper way to do it is to ADD material 'under the chins' on the front EMani so that you can truly match them.

what are logs

He doesn't know your front manifold is cast iron. He'* familiar with the 'log' style from 87-94/95 that is welded tubular. That style really needs no porting.

ok, thank you...well heres what i'm looking at for cost if i send them to w-body...$50 for a jy set of manifolds and the cost to p and p them (189 i think) plus the cost of gaskets and shipping...that will give me something to go by to tell my parents. thanks you for all of the help, i'll let you know when i get them installed

by the way, what kind of power gains should i expect with pems

edit: thank you for the offer peanutbuttaguts, i don't have logs and really don't have any downtime this is my only car and i travel 90 miles a day to work and back

no problem, I thought that they were a cast manifold. I call any cast iron manifold a "log" just cuz most of them look like, well, a piece of beachwood. I have never even ported a gm manifold, just lots and lots of DSM and starquest log manifolds, all for turbocharged vehicles which benefit ALOT from porting the mani. N/A motors on the other hand, well, I don't really know if its worth it at all.

i figured I'd offer, because to me spending about 250 bucks for minor, even trivial gains, wouldn't be worth it to me personally. But then again I have not seen a dyno sheet before and after for a gm 3.8 with PEM'*.

Are you running the supercharged engine? if you are i'd expect MAYBE 10-15 horse most, and thats if the rest of your exhaust is up to par with what it needs to flow to be "free flowing". if you aren't I'd slap some not leaking mani'* on and save the money because for the couple HP you MIGHT get on the top end, you will most likely give up a little low end grunt. for all that work, you may end up shifting your powerband up higher in the rpm range, maybe make a few more peak hp, but overall have a car that seems slower unless you are wide open higher in the rpm range.

Peanut, the front cast manifold on all S2 cars, whether supercharged or not, is a restriction.

The price is because the person porting them has to ADD material in order to properly port them. Then they are coated.
