After 3 weeks of gathering parts and ****, I finally assembled the white TII in my drive way.

Now this motor has no mop, no vacs nest, no emissions what so ever, no bac, no egr, and only has one solinoid, the twin scroll one.

Well to my absolute amazment, I put it back together and VROOM.
Fired right up.
Holds an idle at 2k .
Im almost positive this is due to us removing the coolant lines in the throttle body and not removing the thermo wax or fast idle cam yet.

BUT when you step on it is backfires and chokes it self out if you hold it past 3k.

Now I have NOT hooked the twin scroll up yet -
but would that hurt the power past 3k, just sitting there in neutral and reving?

Therese also ALOT of smoke, guy put ATF in it before he let the motor sit for 5 years. So its still burning off, along with all the lube and crap we used putting it together/in.

Friends comming over to get car/ help diagnos.
But any suggestions welcome.

 

Fixed the idle- it was the throttle cable being tightened wrong.

Will hold a 750 idle, roughly.
Connected twinscroll and solinoid.

Still will NOT go above 3k .

Now. The secondary injectors.
I had to re wire one of the connectors because it broke apart. If this one was wired incorretly, could this cause a problem?

 

damn forum

 

u did a compression check on that sucka yet ?
that would be the 1st thing i'd do

 

Is this a freshly rebuilt engine? because if it is, wouldn't the engine by default have problems revving high since it's not broken in yet, I think before it's broken in there is a bad seal with the apex seals and the housing causing bad compression so this would cause hesitation and sputtering. if the engine hasn't been broken in yet head here for a write up on break in process

 

Na this is a running pull from another car with 100k on it.

Ill compression check it tommorow- just and ear check and it sounded great.

I dont think one of the injectors is working,
mabey running on one rotor .

 

post some pics of the engine bay plz, i want to see, and do you have/did you use some sort of write-up on what you can ditch easily, and how?

 

so a secondary injector with one of the wires soldered on the wrong wire wouldnt affect this?

you can rev it up at idle and it struggles, backfires, and shoots flames. you have to fight it to get up to 3k.

what about a bad primary?

switched fuel lines?

the banjo bolt mod on the primary rail that we did?

please help

thanks

 

the only thing that would keep my car from reving past 3k was the TPS not being plugged in?

check that and make sure???

just a thought

 

incorrect secondary injector wiring shouldn't have anything to do with it. and even if you swapped the leads on the injector, it would still work fine.

it wouldn't run at all with switched fuel lines.

wouldn't hurt to check timing.

 

figured it out.

thanks guitarjunkie = dave

 

so??? whats the answer .. you need to post that so people searching later will have an answer too

 

crossed injector plugs = no fuel to front rotor...secondary plug in primary plug spot =O
