I agree.

Is there a reason you wouldn't run less than 91 in a fuel injected vehicle? And some of us are pretty strapped for cash and don't spend moeny on higher octane when its not needed.

Yeah, I just filled up with low octane, but I might fill up with the high octane next time (until I can get to my timing light).

Well then I might back my timing down to 10 degrees because I don't have the money to be putting in 93 octane, lol.

I'm running just regular gas right now and it seems to be running alright. Thanks for the replies.

That's what I set mine at, seems to be running good. Just wondering what others are running.

What timing do people run? The TSRM Manual says the spec is 10 degrees before TDC. Is this what you run or do you advance it more or less? Thanks.

Hey Mid-Illinois people, I need some help. Does anyone know of any machine/speed shops in Peoria that do good work?

So here is a write up on the problem I am having. After I get the plugs out and am ready to do the sealing, does anyone have any additions to this write up? Anyone who has done this with some suggestions of how they did it would be greatly appreciated. Thanks in advance...

Alright, thats what I needed to do. Thanks.

Thanks, I'll look into that. And I would hope it wouldn't crack the head, wouldn't be very productive... Also, what does everyone think about a blowtorch to heat up the plugs to help break the seal? Any ideas?

Thanks for the solution, but if anyone has ways to get them out, I would rather do that then make more problems for myself later.

Ok, so to continue with this problem.... I cannot get two of the plugs out, one came out, but the other two wont budge... I have been going at it with PB blaster and a breaker bar with a jack handle on the end. After that didn't work and threatened to strip the hex holes in the plugs, I...

Hi all, I was wondering if anyone else has had the problem of the 3 plugs in the head between the spark plugs leaking coolant. Here is a link to a write-up on the problem. http://www.cygnusx1.net/Supra/TechTips/head_coolant_leak.aspx If you have had this problem and used an approach...

I have the red plugs in, well they are out now because of trying to find whats leaking. Poodles, when you say the hose at the back, do you mean just the hose, or the thing that it plugs into that screws into the head? I guess I will check both the 3 plugs that have coolant under them and that...

Hi all, I have a semi-big problem that I don't know how to fix because I am not familiar with the inside workings of the engine head. Posted is a picture of the top of the head. The RED and BLUE circles represent the holes where plugs go. Does anyone know what goes in the RED holes and what...

Sounds good. Thanks.

I just received my ARP head studs and am about to put them in. I was wondering if anyone else has done this upgrade for a 7M-GE. But my main question is the torque spec. My book says 59 lb-ft and the ARP instructions say 90 lb-ft. So which do I use, or what have other people done when...

How would I even start to try to find whats drawing current while the car is off?

Hey all, I have a buddy with a 1990 RX-7 with a battery issue. He is on his 3rd battery in like 2 months, the last one he put in last week, didn't drive the car, and today the battery has half a volt of charge in it. Any ideas on what is happening? Every battery he puts in it just dies. Thanks
