Gambit's 93dx build

[gambit686]

I tried hooking it up all different ways. It is run directly to the small vacuum nipple on in between the motor and throttle body on the manifold. even if i half throttle it it does the same. So essentially at any psi it will do it. Just specifically the car wont rev under any sort of load past 4k.

You know now that I think about it I might have the wrong spark plugs.

Ok so the plugs Im using are ngk iridium 4919. Here is the pn BCPR6EIX-11

if your FPR was hooked up backwards, the car wouldn't run lol.

18psi with a vj20? might be the issue tho, try to dial it back to under 15psi and see if it happens again...probably maxing out the injectors lol

I've hit like 1.7 bar on 330s, that's about where they max out on a VJ20 lol

I'd check your wastegate actuator, the internal gates on IHIs are garbage

hmmm, running the 4 wire tps?

those plugs should work fine btw

The wastegate isn't hooked up.

I'm having the exact same problem as this guy. But the thread didn't get resolved.

Yeah I'm using a 4 wire. I had it hooked up for almost a year before when I was na. Now the weird thing is I can pull the wires fot the 4th dist wire and 4th tps wire and it doesn't run any different. Weird huh??

[gambit686]

Maybe I have a bad blaster coil and too much plug gap?

The wastegate isn't hooked up.

Uh, like at all?

[Turpro]

Bingo. Hook your wg up.

[gambit686]

Alright. I have to tap into my side mount cause I have no other vacuum source. But howcome it would still do it at half throttle to? Watching the guage I'm only boosting maybe 5 pounds and the same thing happens.

[gambit686]

I hooked it up to a vacuum source up on the manifold and it didn't seem to change anything. I think the source was too weak.

[gambit686]

I think I have a vacuum leak too cause my boost guage needle shakes like crazy.

[Mazda_Powered]

your wastegate isn't hooked up? lol that'd be your problem man!

add a vac nipple somewhere and continue on lol, unless you want me to send you one of my "fancy no-welding necessaries barbed vac lines"

[gambit686]

Hopefully I can get to it tonight. Why would it cut like that though? Even if I'm under the pressure required to boost cut? I'm gonna have to tap into my intercooler for a fitting.
