i have a 1987 t11 swap done to it jdm motor just got rebuilt street port done same time as rebuilt only 550 miles on it...

THINGS DONE TO MOTOR
fmic
downpipe ex.
pineapple racing block off plates
fcd
hyper grounds

PROBLEMS...
when fcd is on has random hessitations but boosts way harder then when i take it off doesnt hessitate but feels sluggish

car starts fine when cold but floods when hot

low rpms 500-1000 car will almost dieout if you dont rev it up before letting clutch out

.................PLEASE HELP SOMEBODY...............

 

How much boost? By adding an FCD, you eliminate boost cut at 8.6 PSI. However you will run the car lean...This could account for the "hesitations".

The low RPM problem sounds like a vacuum leak.

 

You have a streetport? ANd are trying to boost higher than 7psi?

WHat are your fuel upgrades?

 

i have a walbro 255 fuel pump stock fuel injectors


and come to think about it i took off my boost controller so its at stock boost so yeah i think your right about it running lean thanks guys!

any other suggestions would be greatly appreciated thanks

 

That fuel pump is going to pump to much fuel.

My TII is running rich just like yours. I would recommend buying an rtek 2.1 and having the fuel tuned.

Have you had the injectors cleaned?

 

no i didnt get the injectors cleaned will be doing that but wouldnt the stock fpr take care of to much fuel entering the motor and making it run rich??
