Looking for recommendations for ignition systems. Currently running a MSD DIS-2 along with a Digital 6. Looking for something simpler with enough juice to protect at 15lbs boost.

 

HKS Twin Power should do it.

 

Yup, I love my twinpower and wish i went to it years ago

 

If you dont already have a stand alone i would recommend the TEC GT. It comes with a whole ignition kit, more powerfull than the msd and old rotary pro pak. If you are looking into getting a real ignition on the car you would need 3 coils and ignitions. So this is actually a little better price and give you a stand alone as well.

Price is around 2000 - 2400. Right now Impactwrench is selling his for i believe 2000 or so.

 

I currently run the Jacobs 1000. The Link below has more info on it.

bad idea to run the fc1000. you will need to run a fc leading coil with it. it wil burn out the 3rd gen coil.

If you want something good and in a fair price range, than do the jacobs pro street ignition with the msd blaster coil...this will be a very nice setup and howard coleman did a write up on it not too long ago.

 

or you can do 3 msd 6al and 3 msd blaster coils.

 

Honestly, I've run two different jacobs amps over the last 5 years, and I'm pretty glad I switched to the HKS.

Jacobs: only work at WOT, only works on the leading coil (unless you run more than one).

HKS: all the time, all coils/plugs.

Also, (and I've posted this like 17 times before) Chris at RP tested a twinpower on an oscilloscope and found it to be a twin strike system, not necessarily an amplifier. That's not a bad thing either

Seat of the pants differences I found? car idled smoother, more initial torque on throttle tip in, definitely more responsive just driving around town. Car also broke traction a lot easier (5k rpms in 2nd), so I would assume that means I was making more power

 

Thanks for the info. Will go with the HKS. Was also going to put all new coils on, OEM, any problem with this or would you suggest somehting else with the HKS. Just getting into RX7's so I'm learning.

 

FC1000 with fc coils ftw.

 

can we run any aftermarket coils on our cars with the hks twin power? or are we stuck with the fd coils? and are the fc coils better? sorry just askin dumb questions since they got brought up.

 

HKS twins +1

 

There is a reason the Jacobs ignitons burn up FD lead coils, the jacobs puts more power and charge time to the coil than it can handle,

The twin power aparantly doesn't.

Yes the FC coils are more robust.

I'm running 2 cheap 120 dollar each summit digital CDI boxes which are sililar in output specs to an MSD digital 6 on 2 seprate old school accell super coils that I got for free, running one too each plug, this is on the leading, I see no point in modifying the trailing ignition.

This 250 dollars worth of lead ignition will jump a ~6" gap in open air between a plug wire and the block and has no problem what so ever keeping up with 50/50 water alcohol or 100% methanol.

 

hmm so its a good idea to score a set of fc coils if your able to do so. and run the hks unit. hmm interesting..

 

I would look at your goals. The HKS is an effective unit. Although, I personally wouldn't use a "re-strike" system for a higher boosted application.

My car uses 3 ignition amps and four msd blaster coils... Don't ask

 

^i think i saw your thread in the single section...INSANE!

I would like to understand why you would not use a restrike system? I guess I kind of like that they have a multiple strike at low rpms and but is amplifing through the whole rpm range.

 

What do you mean by HKS twin +1 ?

 

it just means he votes for the hks twin power

 

I went with the MSD DIS-4 with 4 Blaster SS Coils. A lot cheaper than running three 6al's and saves a lot of room. I haven't installed it yet though since i'm still working on my build so i can't tell u how well it works, but its basically four 6al's in one box.

 

Nope its not 4 6al's in one box, its one 6al with a mechanism that switches its operation between 4 channels.

It won't work because there has to be at least 30 degrees between firing channels.

There is far less separation than that between lead and trail (obviously) under any running conditions, and so it won't work.

 

Twinpower+1. I have run 18psi with no break-up whatsoever. Going on 3 years w/no problems.

 

very nice!! I aqm eventually going with BNR's and I want to try and replicate what rich did with them! 420rwhp whoo hoo!!

 

Can you use the HKS Twin Power with a Haltec E6k EMS with out having to be an electrical engineer with a PHD in putting two systems together? If so is there value to getting the Twin power harness?
Thanks, to all who respond.

 

The twin power harness makes the install a snap with just plug and play installation.
