Hey, I've been using B8EG plugs gapped down to .015. They are actually motorcycle race plugs, but they work good. You'll need a very thin wall plug wrench to tighten them, or you can just use vice grips. I have also used BR8EQ and the stock plugs from a TII without any problems. But Robert reccomended to not use the BR8EQ's, I think they might cause detonation a little easier than the others.



Did you get the Draw-Thru system from Logan's dad? Are you running it like that or did you change it to blow-thru?

I got the draw through system from Ken and I'm going to run it like that until i can afford an intercooler and a blow through setup (maybe I will go fuel injection). It'll be about 5psi and 200 hp.

Cool, my car is down right now. It's getting another upgrade :)

Street Port and stud engine(alternitave to pinning), rotaryshack apex seals
Weber 48dco-sp
Custom intake manifold
New downpipe and rear bend in exhaust
MSD 6a
Intsall IC


I'm not sure about the IC though. I might just keep it non intercooled and sell the IC. It's two stock TII IC's, one end tank cut off each and the cores welded together. I gotta decide if I want to run an IC or not soon.


It'll be ready sometime before the end of april. I have to have it done to take it to the rotary revolution.

You dont have any extra plugs do you? I'll buy them off you. Ive got 2 weeks to get this car running hahaha so im kind of in a jam.

I've got a set of worn out BR8EQ's, I gave the set of TII plugs to Nick(NLC1179) when he bought his TII. You can get the B8EG's from www.ironpony.com here in columbus. I think the BR8EQ's would be fine to use if you have them. I ran them for a while without any extra problems. I detonated the shit out of it with all 3 types of plugs until I got the carb and fuel pressure right. Then it ran fine with all 3 types.

What plugs do you have to use right now?
