Debating Wether Or Not To Go Spitfires

[CEF11E]

I have a moderatly tuned RB20 with the following mods

Sliding performance hiflow rb25 turbo

GTR injectors

GTR fuelpump

3" turboback, split dump, metal 3" cat

remapped ecu, FMIC ect

I am having a miss when running anything over 16psi with the stock coils (suprise suprise)...

I have ngk copper v plugs gapped to 0.8

Currently with 16psi the car is making 215rwkw. If I wind up the boost to 19psi it will not miss the first 2 runs and it makes 230+rwkw. the car also feels quite a bit faster. after that it all goes to s*^t

Should I stick with 215 and stop spending money or shell out another $600 for spitfires and be able to run the full potential of the turbo and make around 230rwkw

Is 15 kw worth $600?

or should I gap the plugs down further?

[Beer Baron]

yes buy them. it's not very much money for brand new coils.

[2BNVS]

buy them, you'll chase more power might as well get em now hehehe

ben...

I had the same problem except mine was missing at 13psi

Got splitfires now and i'm running 18psi.. definately worth it, as with the extra boost there's more power across the rev range not only just at peak.. so it's not "just an extra 15kw"

Also gaping your plugs down, will mean shity fuel ecconomy, i had to run 0.6mm on stock coils, cos they were shot, now 1.0 and ecconomy 100km better.

The people have spoken...

Spitfires for Christmas Wooo Hooo!

[SECURITY]

have you tried my clean with the dremil drill jobbie?

i reckon give that a crack before you spend $600 on new ones.

put the car back on the dyno today and had bad results due to the coilpacks.

The car only made 204rwkw due to only being able to run 13psi. the car did manage to make 5200n tractive effort but was serverley hindered by missfire.

the afr was perfect on 12:1 from 4000 to redline. so that and the 10 votes for spitfires and none for stockers I have ordered the spitfires.

Really hoping for a solid gain and ability to run 18psi. The funny thing is I was able to run 18 for about 3 weeks and the coils have gradually gotten worse.

the car made 230 before the coils fuc$%d out so thats all I am shooting for.

[WazR32GTSt]

you'll soon spend the same amount on worthless dyno runs if you don't go the splitfires...

worth the cash in the long run if you plan to own the car for a while

I wasted hundreds of dollars with secondhand coils and remote coil setups, none of which solved the problem.

Haven't had 1 miss since installing the splitfires

DOOOOO IT!

I found perfectrun to be the cheapest - $535 delivered

The splitfires stoppped all my missing issues. Though I think my stock coils were f'd. They are just a good realiability upgrade more than anything.

Splitfires ALL THE WAY! its proven to give a 10rw/kw increase... ill be getting a set as soon as i finish my turbo upgrade...
