ITB's for LS engines
No updates?? In the time since this thread was started, I found/MADE time to handle the following:
...and I still haven't seen pics of this ITB setup, or a sketch... or anything...
- Go to SEMA
- My flexplate blew up on the drive out to SEMA, 30 minutes away from Vegas
- Had the car towed to my parents place 100 miles away from my apartment, ended up not going to SEMA
- Only worked on it every other weekend, due to the 100 mile one-way distance, with a DD getting 16MPG highway
- Purchased/built all of the remaining tools necessary to do an engine/trans pull/replace w/o a lift
- Pulled the motor/transmission
- Disassembled the motor down to the bare block
- Brought the bare block 100 miles back with me to the apartment
- Purchased all of the forged components necessary to rebuild the block
- Had the pistons coated by a local reputable aerospace coatings company
- Brought the block to a machine shop for initial cleanup/honing
- Paid a more reputable shop to properly assemble the shortblock
- Two months later it was complete (delays with the shop and my ordering/coating parts).
- Got a base tune put on the PCM
- Brought the shortblock 100 miles back to rejoin the car
- Turned the shortblock into a longblock
- Installed the longblock and transmission into the car
- Bled the brakes, changed all the fluids, and got the car running
- Retuned the car with a wideband and a couple of days of street tuning
- Had the transmission fail
- Found a built transmission 80 miles away
- Drove 160 miles round trip to pick up the built transmission
- Drove 50 miles to pick up the stock torque converter
- Installed the built transmission
- Now fixing other various quirks due to the car being down for 6 months and undergoing a new forged/built setup
- imagine JUST the fuel cost of all of that, considering my DD was a 4.0L Jeep that got probably 16MPG highway.
- now realize that a Harrop costs the same amount of money as what I spent on the forged motor/built trans project
...and I still haven't seen pics of this ITB setup, or a sketch... or anything...

At one point I was pretty much dying from a combination of bronchitis, the flu, and asthma. On a sick day (a week before I had to go to the ER), barely being able to stand, I brought the motor from my apartment to the motor builder and unloaded it at the motor builders shop. I place a lot of priority on car stuff, I guess. But this thread is just a tease. However, I had a lot of motivation: my Jeep was a money/gas-guzzling POS. Whereas I am unsure of how much motivation the OP has.

Not familiar with Kinsler. My experience is limited to Harrop and Jenvey. Harrop is the only option for DBW right now. Harrop has a common plenum, and provisions for an IAC and MAP sensor common to all ports.
Jenvey is 8 seperate throttle bodies and ports. No common plenum. Jenvey, with no common plenum, has no IAC (remember this is cable, not DBW) and also, no real provision for a MAP sensor. So, it's MAP in one port, or Alpha N.
Just sayin........
