I'm torn between new coils and DLI or the 1zz coils. Obviously the 1zz coils are the cheaper route but I'm still skeptical of whether or not they out perform new OEM ones with DLI. I'm pretty sure I can't use DLI with the 1zz coils because of the built in igniter, but can anyone confirm that...

Would not having DLI and running wasted spark make it run this weak at 19psi? It doesn't begin to miss though until 19.5-20psi. Air/fuel is around 12-12.5. Before tuning, the shop took compression and leak down: (#1) 161 with 1%, (#2) 150 with 5%, (#3) 164 with 2%, (#4) 166 with 2%, (#5) 165...

Help me figure out whats wrong with my car here: http://www.supramania.com/forums/showthread.php?t=107443 Coil packs were wrapped in A LOT of electrical tape. No DLI.

BKR7E with .026, it was a mustang dyno so add roughly 15% to get a approximate dynojet number. ~450whp

I just got back from a disappointing turnout at the dyno with the stock ignition. It wouldn't take more than 19psi with a T67. So are these 1zz/2zz coils the ticket for a better spark with a stinger? Or am I better off with new 2j coils and DLI? Whats the verdict?

Made 390 @ 19psi before misfiring on the stock ignition. :wtc:

On Friday I was given was some bad news. The Tial knockoff wastegate that comes with the Driftmotion kit was leaking quite badly from the diaphragm. So I ordered a new genuine Tial gate which should be here either today or tomorrow. I learned a valuable lesson though, no knockoffs, Ever!! Even...

I dropped my car off today for tuning and I'm curious as what you guys think it will put down when its all done. I will post up the results when I get them but keep in mind that this is being done on a mustang dyno. My fingers are crossed for 600whp. Here's the mod list: 1jz with stock...

Which way do I wire up a 1jz igniter? Do I tie the coils together for wasted spark before or after the igniter? Before: After:

Stock cams stop building power a little over 6k, I've taken mine to 7500 countless times but there is no additional power to be had up there. I upgraded to BC 272's and BC springs/retainers, peak power at 8k and 9k float limit.

According to what your saying you have no boost in 1st and 2nd then? The engine doesn't care what gear your in, both turbos should spool up in every gear.

My car looked like this when It was done: Yours should look like that too if you keep it clean. If you have any questions about it I will glady answer them.

No spark or fuel, do you have 12v on the Black/orange wire that powers the positive side of both the coils and injectors. It should read 12v as soon as the key is in the ignition position. That was a problem I just had with mine. Mine still doesn't run though. :nono:

I don't know if this will help anyone with what could be wrong, but now when i try to start it doesnt just crank its a constant sputter now. The sputtering sounds like a pop pop pop pop pop pop then the starter almost stalls like the engine gets tough to turn. Then its back to popping.

I put in a walbro during the swap. I don't have an FPR so I can't be positive on the pressure, but it does smell pretty bad of gas when I try to start it. I checked the spark too, its all there. As for the fuses, I checked all of those too.

Okay I checked the IGF wire at the ecu with an oscilloscope, I have a square wave pulsing from 0 to 12v. Does that sound correct to any of you? Also I checked the crank sensor wiring at the ecu, that has a pulsing sine wave. Its not random pulsing either, perfect pattern. So my thought is...

I have cranked it plenty long enough. I think my starter may even be going bad I have cranked it so long. It sounded like it wanted to go so I kept trying to get it going.

I just got finished wiring my 1jz into a s13, and of coarse it won't start. I searched these forums up and down for hours looking for clues as to what it could it be. I found some good info that helped a little bit, but still, no go. At first it would just crank and do nothing, I mean NOTHING...
