Couple pics of my TBI after mods

Heres a couple of pics of my tbi on my 92...I did the "ultimate tbi" mods minus the adj fpr for now.Also added a tbi spacer and a pod spacer...I can tell that it has a little more torque now I'll take it to track fri and see if times improve..

I ran a one inch spacer under my stock hood but I had to use a drop base air cleaner and I cut about a 1/2 inch off of my air cleaner stud.

The Idle was a little high when i first installed it,But I took the plug out of the TB and Idled it down..The rest of the Idling is computer controlled and had no trouble with that..It was only when I would come to a stop it would idle to about 2500 rpm and gradually decrease.Once I backed off the Idle screw I come back down to about 650 pretty normal now...
I had absolutly no trouble with the spacer or the linkages.
And dont buy the fuel line extensions either all I had to do was unbolt my brake booster vac line from intake and bend the bracket a little to go under the fuel lines and everything lined up perfect and looks like its supposed to
I took a piece of threaded rod and cut and bent it to length..I'm running the spacer and 5" of air filter (double stacked to get up into cowl..14x3 K&N and a cheepie 14x2 paper filter)I just wanted to get the K&N up into the cowl
Your not gonna notice a big differance but I did notice more torque throughout acceleration..
I'm going to track fri and try my luck again..If my clutch will hold out...
