7mgte spark plug gap?

[whiteturboz89]

hello, i ran a search for the spark plug gap size for the 7mgte, and cant seem to find it.

sry for reposting this question, but whats the correct spark plug gap for the 7mgte?

gonna be using ngk g power platinum

plz and thx for every1's time

 

[madsupra88]

.8mm or (0.031in) i usually go 0.035 in

WHY??

http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=IG&P=8

Correct gap of new plug:
7m-GE 1.1mm (.043")
7m-GTE .8mm (.031")

ahh you just posted the exact thing i did!

notice how i put ..............7m-GTE .8mm (.031")



as for me thats what i set MINE at. (higher comp for me) @ 0.035''

No

You are setting it at .035" that is exactly .004" off from TSRM brand new specification!

Higher compression requires a smaller gap. Same with higher power production.

 

[madsupra88]

Higher comp requires smaller gap? arnt the n/a supras higher comp, and also have a bigger gap !?!?! thats exactly .012 more the 7mgte.


Also being .004 off is NOT a big deal, maximum gap for a 7mgte is .039!

either way, do as you please.

the N/A have a higher static compression but the turbo motor have a higher absolute compression thanks in no part to the turbo. HENCE why the turbo motors must run a smaller gap or risk a blow out of the spark.

Do as you please, correct.

But don't come back crying a river of why things are not working when the TSRM is very specific of what the measurements are! :3d_frown:

I might as well ask the question I've been thinking about now.
What about a N/A motor running smaller gap (turbo gap, that's what I had my old plugs set at)? What happens?

Nothing. You might lose some combustion efficency but it might be negligble.

lol ok i think my motor well survive gapping my plugs at .035 when it specifically says in the tsrm that the max is .039.... ive owned 3 supras so far, always same gap, also a low 10 high 9 supra as we speak!! and never a problem.


In all honesty you need to have a little more respect and act like an adult, you took this waaay to personal bro! anyways im done here.

excuse you? **had to open the shit storm didn't you.**

Just because you are ignorant and chose to interpret what is in black and white to your agenda does not make it right.

But since it seems like reading comprehension is lacking on YOUR part.

I specifically quoted the TSRM for a reason.

Correct gap of new plug

Notice the choice of wording used by toyota (even with my ommision of the word electrode).

It is not ambigous nor is it speculative. It is very very specific on what type of spark plug and at what to gap that plug at and also that this is CORRECT for new spark plugs.

Not .030 or .032 but exactly .031 for a turbo supra. If that statement is for new then the other statement for MAXIMUM is for used plugs NOT new. Why? Because spark plugs like anything else do wear away and if you are at max gap you will be beyond spec and the propensity for spark blow out will increase substantially.

Now with that said, you could be Ken Duttweiler. In here, if you post bullshit like you did. You will get called on it.

**sigh**

Ok, my first post was quoted rite from the tsrm. but i added a note sayin thats what i set mine at. does not mean that im telling him to set his gap at .035. and lets be real here ... being at .035 is not gonna effect the motor much at all.

setting the gap at .035 is NOT gonna blow your motor up. period.

now are you done with your shit fit, cuzz being a keyboard warrior is not helping this discussion at all.

-saif


Also... dude.. seriously take 10 sec ... well maybe 20 sec for you and actually read my first post... take a deap breath and read it carefully. and think about this whole shit fit you threw over this.

don't need to.

If your post would have stopped at .031". That would have been it.

For some reason, you must have found it beneficial to state that you gap to .035". The purpose behind the statement is irrelevant.

It is wrong information on all accounts. End of discussion.

That like me stating I run .042". It is WRONG but prior to this you did not see me posting that information as it is again, irrelevant to the ops question at hand.

technical accuracy or nothing.

 

[need new tires]

i am with figgie on this one

you need a tighter gap on a turbo motor on a stock ignition and stock heat range plug.

advising otherwise is very misleading.
