Yeah me too I just wanna get it perfect before I see the fruits of my labor. I just went for a drive to burn off some of the crap gas in there and got a TPS Voltage Too High blinking in my face. I rigged up a ghetto adjustable TPS 'mod' and thats probably the issue. I'll check in the morning..anyway - sooon

hte TPS thing will go away after some driving ( i think it took mine about an hour or so). There is a TPS learn procedure, you turn the key to on (not the engine on) and let it sit for about 60 sec and then start it. Dunno if it will work for S1.

Yeah I checked it out today, idle voltage was .74. I played with it now idle is .40. I started it up and it went to 2000rpm on a warm engine. Its funny, I thought I remembered hearing about that KOEO relearn trick so I tried it and when I fired it back up the idle was perfect.

I put some tolulene in it after that and did (~95-96octane)
10-50 = 0-2*
20-60 = 0-2*

Its hard to tell how much of an improvement the rockers directly had. Yesterday I was getting 4-6* on some probably horrible gas. The gas station seriously looked shady, prolly got 86octane with water in it. I'm going to burn through this stuff and fill up with the 94octane + Tolulene as tested before. I would have done it today but the only gas station in the city that sells it closed before I could get there (WTH closes at 4pm??)...but the hardware store was open

I'm beginning to think some of it is false. It doesn't always climb with rpm, it'll do 0-3-0-2-4-0-1 as I'm going. Is that normal? BUT here'* the neat part, before the rockers at WOT I would usually see 9-11* of advance now I see 12-13* with a hint of 14*. Is it the tolulene? Is it the rockers? Is it the injectors? Is it a combo? I dunno, but its happening.

I'm getting new belts tomorrow, ~100miles on the gatorbacks is aparently too much. Its funny the belts I took off were cracked almost in half but never made a peep, brand new gatorbacks and they squeel...*sigh*.

More tests to come....

lord tell me I dont have to take the power steering hose off to get to that pass side middle rear valvecover bolt!!!!! It took me maby 20 minutes to change all the front rockers, but it took me 30 just to get 5 of the 6 rear valve cover bolts out....jeez GM what were you thinkin? looks like its time!!!

I haven't messed with mine yet. Will these bolt right up to a 92? I might wanna put them in before I have the money/time to get the 93 heads ported/rebuilt.

Far as I know '92 heads have 3/8" holes and '93+ have 5/16".

I take it that'* a no?

Dj, in your opinion, would the 62 cam along with the rockers be a somewhat safe combo with nitrous?

I'm also interested in that ^

But put me down for rockers and a cam. I can be ready when you are.

Not sure which cam to use though. I'm looking for something big, streetability isnt much of an issue but head work is. What kind of clearancing work is really requied to run a .600 lift cam on a series one head. I have a great head shop here that says they can do it but I know price yet :? Im looking for results like a Intense S3 cam or a ZZP XP.

Thanks
Jake

IMO yes. If they used a 1.5 ratio for the cam lift numbers a 1.72 ratio will give you .504" lift at the valve. This would be very close to Intense'* 1X blower cam with stock 1.6'ers. Just a thought but I would assume the duration would be the bigger factor when using nitrous. The valve only cools when its closed, the longer the duration the less time its closed thus the less time it has to cool. I don't think the 62 at 201/206 @ .075" is going to be an issue at all. Just concentrate on your fuel delivery and you should be fine.

JK - Damn, I never really noticed you're using a '92. Dame is right '92 has 3/8 and these are 5/16. They are available in 3/8 size though, I just wish I had noticed that before ordering. You mentioned having '93 heads, were you planning on putting them on it and just curious about your '92? If this is an issue let me know and I'll get right on replacing them with ones that'll fit the '92.
