Default ITB (Harrop) Inake on my LS2 restomod!

Changing things up (again)! This ought to set me fairly far apart from other swaps.. not running yet, but getting very close! Need to tidy up a few details and then take it to the tuner.







The intake is the only drive by wire individual throttle body intake that I am aware of, and I believe I'll be the first C2 restomod with this combo!

I'll have more pics and video after it is tuned in the next couple of weeks.

I'm not stumped easily on ITB setups, but……….
What is the plenum looking "black box" in the middle? vacuum collection point perhaps??
Where are the throttle shafts? I assume there is one shaft running down the middle, under the black box.
What ECM?
That's a very unusual setup for sure. Never saw one like it.

Air filter idea for you that doesn't detract from the look to bad.

There's a common vacuum plenum on the bottom actually.. the top is just a black cover over the mechanical linkages to the eight 55mm TB's. See this file photo from google images:



The DBW motor fits underneath the actuator cam, which could also be operated by a cable pedal as well.

Using the regular (GM) ECM. Just have to switch from MAF to speed density tune now.

Ahhhhh. I see. now that is cool. I like seeing the moving gizmos myself, so would like a clear cover over that linkage. but that's just me.

Uhhh....ok. didn't know that could be done with the oem unit. I use a Holley HP system, which works well for me.

Thanks for the added info. Looks very nice

Default ITB (Harrop) Intake on my LS2 restomod!

Very nice looking setup.

There is a beautiful '67 Restomod for sale at RK Motors in Charlotte that has a similar style Kinsler intake.

Glad to see you making progress, Yours is definitely the first I have seen on a C2.


You going to Kissimmee this weekend? I'm doing a airport run early then going up I-4 Saturday.

This is a LS swap we did a few years back for any interested.

RJ,
I'm bailing on Kissimmee this year, but hope you're lugging some old parts around for sale
My Tahoe blew the hard line the other day, so I get to rewire the brakes instead.. will catch up with you as soon as the '64 is running again though. I'm gonna need to put some miles on it before the power tour!

Have fun tomorrow, make sure you get an NCRS judge to let you know what you have left to do on your car to bring it up to standard

One thing we have seen over the years is the enthusiast may cut back on splurging on trips, etc., but NOT when it comes to their baby!

Anyone wanting a LS swap, look us up.

Mike,

Looks great and that set up has made some decent power. Brian Thompson of Thompson Automotive (aka Mark Stielows engine builder) built a LS7 with that intake for his C6 Grand Sport. Thing makes brutal power!!

Very nice upgrade!!
