It could be timing related or too lean of a AFR mixture. I sprayed a 100shot on my tr55s and after I did that the truck ran like ****, pulled the plugs and they were all really green...

Got some NGK BR6ef's to replace the old plugs, got timing right, AFR straight and no green plugs.

It doesnt have a sweet exhaust smell, I know what burning coolant smells like from a Previous motor.
I am still running stock timing so didn't think it would be that, A/F is at 13.2
What plugs would u guys suggest for my setup?

Thanks, mitch

Maybe try some tr6s.

Both stock high and low octane tables suck IMO. in low rpm low load areas it can command upwards 50* timing. Too high for my likings...

Ok thanks, I will pick up some tr6s and then check everything again after I get my tune from justin.
What kind of times u shooting for with ur integra? I have a couple buddies running mid 10s at over 130 mph with more boost left in some of them, street driven aswell

Let us know how it goes


Man Id be happy with 11s. I went with the biggest single disk clutch thats only good for 400-420hp (cant afford a $1k twin disk) so boost is gonna be mild.
But I really dont know what to expect yet..
Your friends cars sound mean tho!!!

The Honda I tow to the track is a civic hatch, makes 550 to the wheels with a t70 and still has more boost left, runs 10.6 at 133, his last pass he made was defanitly on his best pass yet, prob a 10.3-10.4 pass until his hood decided it wanted to make out with the window and roof halfway through 4th gear

Thats pretty quick. Im sure he was spinning some too?
Yeah I have seen hoods come off before. Seems to be a common problem lol

GREENSIERRA

Spinning through first, don't remember his 60', thinking he was in the 1.7s.
He was just trying to get his launches set with his new FJO setup.
Hit me up with a pm when u get some times out of urs and thanks for the help
