wait wait wait...back on page 1 you said you were using 87 octane gas with the PEM stage 2? correct me if im wrong but dosent that require 93 octane? hence the ricockulous timing?
About the header not lining up.....They all come like that. Its not a big deal. You just persuade it on with a rubber mallet. NOT a big deal. I had to do that to both of mine when I put it on. And the OBX isnt a crap header.
Yeah, you are supposed to run 93 with the stg 2. I wanted to see if and how much timing it would pull on 87. I do think it runs better on 93 as opposed to 87.
I did get the header on an old head that still had the studs in it. I think I'm going to sand down the flange to try to get it to seal. When you put a straight edge across the flanges there is also an 1/8 inch gap and one of the flanges isn't even straight. If this isn't a cheap poorly made header, I would hate to see one. But, I cant say I wasn't expecting to have this problem.
Maybe if I was bolting this to a iron head I would be able to draw the nuts down tight enough to make it seal, MAYBE. I don't feel like stripping out the threads on my good ported head....
Got the intake ports finished up last night. Now I just have to figure out if there is anything else I can do with the exhaust ports. I can't really open them up any because the header is the same size as the factory ports. I already did the short side radius.
FINALLY! Got the head done tonight. Couldn't do much with the exhaust ports because the header so closely matches it. Cleaned up the chamber side as well. Off to get the bigger seats put in and check it out again to make sure everything is still smooth. After that I just have to get on APTuning to get that crap done!
Then put it all back together...
Got the block back from the shop. Now waiting on the head and parts.... This had better be good!
I'm the only one I know of who will be running this valve kit. Also, I don't think anyone else will do it with a stock MK3 mani! i will be eventually going to a modified MK4 but i'm hoping it makes some serious tq down low for daily driving with this mani. My cam will be a mis-match, but well see how it runs.
How is the baffle setup in the oil pan. There is a baffle that clips onto the pump pickup right? Whats the purpose? I assume to keep the oil in the sump for cornering and such. Is that all?

APTuning is severely aggravating me! They have screwed around for 2 months getting my parts together. Then I went in last week and they told me "yeah, we have all the stuff but we can't find the cam caps..." Great, now the head I spend weeks on is now junk! I'm going in tomorrow and pick up the parts and I'm not paying for them until they produce a ported 8v head! I'm never going to these people again.
