J Taylor Posted October 2, 2000 Share Posted October 2, 2000 I am running alot of boost in my 280Z and would love to have a colder spark plug to go in it. The stock NGK plug is BCPR-6es11..cold would be 7es11 but noone has it or can get it. Have had the same problem when trying to find a colder plug for my 300 turbo as well....the number is 6e11 so I want a 7e11 but can't get it anywhere. Any of you boosted guys running a colder plug???

John Scott Posted October 2, 2000 Share Posted October 2, 2000 JT, I don't know if AC has a crossover for the Z engine, but I've had excellent luck with the Rapidfires. I use number 1. Also had good results with the stock plugs for the Syclone 4.3. I know ACs don't sound as cool as NKG or Bosch, but work great in mine with lots of boost.

Guest Anonymous Posted October 2, 2000 Share Posted October 2, 2000 Local advance auto can get 7es-11 all day long, but doesn't even have 7e-11 listed. S is 'standard', ie. no v-groove, without S is v-groove, plugs same otherwise. ------------------ Morgan morgan@z31.com http://carfiche.com http://z31.com Quote Link to comment Share on other sites More sharing options...
J Taylor Posted October 2, 2000 Author Share Posted October 2, 2000 Morgan....any reason the 7es-11 would not work in out vg30's? What's the benefit of having the v-groove? JT P.S. Someone else told me I could use the BPR-7es or 8es as a colder plug for the 280......should work for the vg30 as well, right? ------------------ 1978 280z with 280zx turbo motor.

J Taylor Posted October 2, 2000 Author Share Posted October 2, 2000 OOps, I meant is there any reason the 7es wouldn't work right in the vg30 turbo.

Drax240z Posted October 2, 2000 Share Posted October 2, 2000 Someone over at zcar.com was mentioning that they were using RX7 plugs in their Z and getting more power... I am pretty sure that the RX7 plugs are commonly available in ranges up to 9es11 from NGK... ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 2, 2000 Share Posted October 2, 2000 "S" means the groove. They would work without the groove, but I'd want it. ------------------ Morgan morgan@z31.com http://carfiche.com http://z31.com Quote Link to comment Share on other sites More sharing options...
Guest scca Posted October 2, 2000 Share Posted October 2, 2000 TRY out the ev series. b8ev its ngk high perf plug. about $4 ea. i run 9's in the race car and 10's on a long straightaway. they are a fine wire tip and less prone to detonation from retained heat. hey and index them as well to get the ideal path. ------------------ Mike http://www.fonebooth.com raceparts and brakeupgrades Quote Link to comment Share on other sites More sharing options...
B00STDZ Posted January 27, 2009 Share Posted January 27, 2009 So whats the best plug to run on a 83' 280zx turbo engine for performance? BPR6EIX-stock turbo spec'd spark plug BPR7EIX-colder BPR8EIX BPR9EIX BPR10EIX-coldest So you will get better performance out of a colder spark plug? this being said the BPR10's are made for snowmobile's Quote Link to comment Share on other sites More sharing options...

Scottie-GNZ Posted January 29, 2009 Share Posted January 29, 2009 No reason why the RB should need a different plug than a 2JZ in a high-boost application. Both Z-Gad and I run BPR7E with great success gapped down to 22-23. Quote Link to comment Share on other sites More sharing options...

Both Z-Gad and I run BPR7E with great success gapped down to 22-23. http://www.ngk.com/results_cross.asp?pid=BPR7E&x=36&y=14 unless u mean BPR7ES: http://www.ngk.com/results_cross.asp?pid=bpr7es&x=44&y=5 the only diff is the S which indicates no v-groove any reason you run the PRojected tip over the standard tip ? I know a projected style spark plug firing tip temperature is increased by 10°C to 20°C and that a projected tip gives you an additional step between heat ranges..... so a bpr7 is like a 6.5 br haha just asking.. And this thread is 9 years old..... Quote Link to comment Share on other sites More sharing options...
