How are you gonna run the IAC on an LS1 throttle body?
How are you gonna run the IAC on an LS1 throttle body?
Same way it is run on a TBI!Originally Posted by trippyjoey
I mean wiring it and are the voltage values the same, or would you need to do some tune adjustments?
No issue wiring it and the voltages are the same. Its a stepper motor with an extend and retract coil. Tune adjustments would be very minor. Big Block 454 TBI units used a very similar IAC. LT1, CPI 4.3 and the Vortecs used practically the same as well.
Awesome!
I'll ask a friend of mine to see if he has his old TB since he put a 408 in his Trans AM to try it since I want to go MPFI on my tbi.
I would use a 454 TBI unit, without the injectors (fabricate a block-off) on a TBI-carb adapter on a marine dual plane MFI intake.
I was originally thinking of using a 454 TBI and the injectors for this build but for the price I keep on finding the tbi units here locally and the internet this seems like a better option. I was thinking of originally using a tpi throttle body.
Some parts came in, waiting on my elbow. I got a throttle body off a 6 liter truck motor. Its pretty nasty, needs cleaned up. The intake has no vacuum ports so I am going to have to fabricate something to bolt a MAP sensor too and some way to hook the power brake booster up. I have a friend with a tig so that's no problem.
For the whole setup being Chinese, I am pretty happy with the quality. The ports need a little cleaning up, and some gasket matching.
LT1 injectors went right in.
This thing might make some serious power...LOL

Looks great you got a link to where you got the setup?

Just look around online for the cheapest prices, most of this came from Amazon

Thinking about buying a boost gauge with a 0-5 volt output so I can log boost. I have my wide band connected to my Autoprom and log AFR through it. Can the boost gauge be hooked to a unused 0-5 volt input on the PCM. Its been a while, I cant remember, seems like it could be done through the EGR or the CPI stuff.

You could use a MAP sensor (2 or 3 BAR), and connect it to another ADC channel of the AutoProm.
I'm not aware of any boost gauge that has a 0-5V output similar to a WBO2, but if you find one, definitely post back, because that would be interesting and useful.
The man who says something is impossible, is usually interrupted by the man doing it.

Mocked this bad boy up last night. Going to have to get creative with my throttle bracket. I need and extra vacuum port for my power brake booster, so I will have to drill and tap the intake for that. This intake has no vacuum ports. Not sure what water neck I am going to use. Going to clean some wiring up while I am in there too. Getting ready for a hair dryer...
I also decided against the intake elbow, apparently when you run one of these NA it can cause the back cylinders to run lean. So I went with this style TB and will be using a carb hat to blow through.

Looks nice, now I have something else to put on the Christmas list.
