anybody here running the hks ignition?? the car is running fine but i want it to run alittle better. anyone hav this on there gs and does it make a differance??

 

It will only make a difference if you are running FI. It allows the plugs to run a bigger gap without a reduced spark. If you are having hesitation (for lack of a better word, you would know what I mean if you have it) under high boost/upper rpm range then a DLI will most likely clear it up.

 

As macd7919 said...no difference if you're NA. Only really necessary to run it if you're boosting 25-30psi+. Low boost levels under 20psi runs just fine on the stock GS ignition system.

 

i'm boosting 14psi, but i notice some spudder at mid throttle. not alot but enough that i might go that route. i'm also running ngk iridium plugs. someone told me i should switch to ngk coppers, $2.50 a plug. should that run better??

 

No, don't switch to copper plugs. Iridiums are the best plug for your application, idk who told you that but yea....don't switch. When you say mid throttle do you mean cruising? If you are getting some sputtering under cruising but not full throttle that could be in your tuning. You could also try gapping down your plugs, a car running without a DLI should usually be around .028 or even as low as a .026, see if that helps.

 

Why not copper plugs? Most of the Supra guys run the NGK copper plugs. I run that in my car as well and it hold just perfect to 30psi.

 

if your running it, then its good enough for me....but i'm still going to get the hks ignition booster..


does anybody know how to install it or hav a diy

 

We have ran NGK coppers, and iridiums in our customer's Supra.
Iridiums will last alot longer than copper, but are bit harder to spark.
Running the DLI on his car and we have gapped down to .018 with it.

My old Supra with no DLI ran coppers and gapped down to .026.
Every car will vary honestly, so there is no for sure definative answer.
It cant hurt you to run one for sure though.
Longest I went on my NGK 3330's was about 7,000mi before they wouldnt hold idle.

I have a brand new never used HKS DLI for distributor type set ups such
as NA Supras, SC300, GS300, etc...

 

I use Iridiums because they work just as well and last way longer. It's not fun to change plugs all the time on these cars and I got sick of burning through standard plugs every 3000 miles.

 

i've been doing some research and i found that MSD is cheaper. but i see that they both do the same thing....i'm going to buy an ignition booster but should i go for hks or msd????????????????.........ngk coopers is on order so i want to do both at the same timeeee. any info would be much help

 

Don't use an MSD, for whatever reason they have a high rate of failure on our applications, that's why they aren't very popular on Supra's/Is's etc...

 

i use the HKS DLI and iridiums not sure what their gapped to but when i added the DLI i noticed it got rid of the slow power loss at WOT above 100. oh and thats at 24psi

 

DLI here too.. don't use the MSD, I've tried. It was nothing but a headache.

 

do u guy hav diy wire diagram for this??

 

HKS DLI has the optional patch harness so you dont have to cut anything and just plug and play for the NA(originally) models.
The turbo models require hardwiring.
