is an ignition amplifier really necessary for single turbo's? is this a reliability mod or a performance mod?

 

I would say yes, since when you hit high boost, you dont want your spark to cut off...I'm not an expert but from experience it does help a lot..

 

i would like to know aswell..

 

It's just to keep the engine running correctly. Ignition breakup isn't just some kind of tuning issue, it's a problem that must be remedied.

 

more smart ppl say stuff please..

 

L8NightDrifter,

You really won't know if you need an ignition amp unless you stick it on a dyno and see how the car is performing. If you see some ignition break-up at higher rpms, you either have a problem with your current ignition setup, or you need an ignition amp.

There is no hard rule that say you either need one or you don't. However, there have been many FD's producing over 400rwhp and not having a problem without an amp.

 

....so if im running stock twins at 14 PSI should i get one? Are there any HP gains out of it? My friend wants to sell me his with the harness for $150, should i get it?

 

If you want it, If not...Ill buy it !! PM ME

 

Actually, there's an RX7 owner here in San An with a T78 who used to misfire until he got one. Said it cleared it right up.

 

$150 with the harness isn't a bad price at all.

 

i run CDI (Autronic R500) on my FC with only 320rwhp (the CD ignition turned out to be a similar price then 4 ignition modules). i was very pleased with the results. it made tunning easier, cleared up idling problems, cold/warm starts like a dream...

however there is no need to put 1 on my near stock FD

 

damm $150.00 buy it..

 

considering what hks twin powers go for, you should just get this one even if you dont need it. Its can only help, especially for only 150 bucks.

 

Just picking up the twin turbo install.

I'm a bit reluctant with the exhaust setup. The flanges against the exhaust section of the turbo leaves very few room for the internal wastegate to function properly. In normal OEM conditions this would be a cast manifold with thesame design to fit the exhaust turbine exactly.

I would suggest to rework the exhaust tube-to-flange setup to give the internal wastegate more room.


What's your opinion on this ioind of twin turbo set up with T3 >Garrett turbo's 42 A/R and shooting for a quick spool 400HP 13B REW engine?

 

Forced induction engines create such high combustion pressure in the combustion chamber at high boost settings that it can literally drown the spark energy of the plug during the ignition phase. Fortifying the strength of the spark ensures that much more of the fuel/air mixture gets burned, obviously resulting in more power.

However, this doesn't mean that all FDs need an ignition amp or different coils. Much depends on the ignition curves, a/f settings, etc.

 

alot also depends on the fact that some people have 10+ year old coils
