[Header and camshaft ?]

I have a feeling both JWT cams will give you trouble with your idle scores for emissions. (especially the S2)

Is there anything specific that makes you feel that way? I'm kinda new to all the aftermarket stuff and looking to learn as much as possible. So far I haven't found out what the math is to figure out what the cam would do to my emissions. If you have a website I should check out I would be very grateful.

 

Any thoughts on the nissan #2 cam?

Hey Bud, I'm just over the hill from you in Santa Rosa!!

 

Ok, first off, SEARCH!!!

 

Now that we have that covered, cams are good, headers are good but cams and headers are better. Thorley resumed production of the WD21 headers, I have a set that I put on about a year ago and they fit/work quite well. Pace Setters are another option but are generally considered lower quality, painted not coated and there are mixed reviews of installment issues. They are also quite a bit cheaper...

Also, the cams may be an issue if you have to smog the vehicle and unless you have the ECU reprogrammed, you wont get much more out of one than a stage 1, or 1 step up from stock so no point going further.

Hows the weather over there?

 

Thorley discontinued production again on those headers and are not commiting to a date to resume. I am going to get there list of vendors that they last shipped to today and start calling. If all I can get are the pacsetters then so be it, but man I have read some horror stories about not fitting or craking after only a few years of service.

 

Ultimatly my idea was to put one of the JWT ( part numbers AZ314-000S1 or AZ314-000S2) cams along with there upgraded ecu (ED210-NMC60). exhaust it all through some thorleys and figure out a decent high flow cat and muffler. Im not sure it would smog at that point I still need to do more research. I just got the pathy a couple months ago and just got it running good and smooth this month. Seafoam is king

I'm planning my projects for my 1990 5spd. autozone special.

I was thinking I would get a new cam and rebuild the engine (178000 mls) my main question is if I am stuck with a stock exhast manifold will I get any improvement from that new cam or will the backpressure in the manifold negate any gains from the cam. As I understand it without having a good exhaust useing a performance cam can cause problems

 

The other question is does anyone know for sure if

A. There are any doug thorley headers out there left?

B. would they work on my pathy

C. Any other viable options for headers?

 

Thank you oh pathfinder gods for assisting this lowly newbie.
