What can be removed or plugged off on my TPI intake?

What things can I remove or plug off on the TPI intake to clean up the looks (no emissions)?

I will not be running A/C, EGR, or heater hoses. The obvious items are to block off the EGR, and plug off the outlet in the front of the intake for the heater hose. Anything that cuts down on the # of hoses and harnesses will help me out.

Thanks

I am doing the same thing. Even removed the 9th injector. Now after doing all this what do you do with the tb coolant connections? What vac hoses need to be rehooked now that the egr valve and the egr solenoid are no longer there?

Re: What can be removed or plugged off on my TPI intake?

I'm thinking about doing the same thing on my 85 LB9 Iroc. I am getting a re programmed chip that deletes the cold start injector, but I'd like to remove the EGR too.

Let me know what you guys are doing and maybe we can get a good conglomerate together!

Re: What can be removed or plugged off on my TPI intake?

You can reprogram all this by yourself if you have the tuning software / equipment (no EGR, AIR, AC, 9th injector, etc.). 9th injector removal especially is a good idea.. one less leaky POS to worry about, with the 6E code you don't need that 9th injector in there to start the car.

Re: What can be removed or plugged off on my TPI intake?

This whole computer thing is new to me. I'm young and still know how to set up dual points and dwell. Lol

This is my first computerized car, so everything is new to me. Heatzone25 is supposed to be making me a chip so I can eliminate the 9th injector and I think I'm getting rid of the EGR too. This car runs pretty now, but I know it needs work. I just did the complete cooling system, including high flow water pump, radiator, hoses and thermostat. I also stabbed in a transmission cooler while I was at it.

Run the heater line direct from the intake manifold to the heater core and delete the TB heating on the IAC housing

If you have deleted everything all you need is vac from the intake to the fuel reg and to the HVAC / CC/ vac ball
as well as the large vac line from the TB to the canister purge

Typical TPI vac setup shown

Re: What can be removed or plugged off on my TPI intake?

I just did the throttle body bypass on mine, since I was doing the water pump, thermostat and radiator anyway. Since there's no water control valve I bought the Lumina heater hose and put a plastic 90* fitting at the stock heater hose, which had to be cut just before the elbow. I'll post pictures tomorrow.
