FITV less TB's
 

Looking or a option to delete the FITV, Im thinking block off plate and permatex, and bypassing the two water lines. Every OBD1 TB I have seen has a FITV, havent come across any OBD2's to even see it they will fit on my Z6. When I find my DOHC ZC tb I suppose I'll try it, even though Im sure the vaccum ports are way off, Firewall mounted MAP FTL ( Using TB MAP)

metal plate and seal it off


no water lines


done


obd2 no fitv

i think i have a blockoff plate from a aftermarket throttle body i put on a buddies integra; if you dont feel like making one. It still had the water line going in and out so you can feed your iacv from the other side.

Cool, How much would you sell me the block off plate for sohcpwr? I am lazy after geting off of ework, but I prolly a make one unless yours is cheaper than the time I would spend foopling with drills and die grinders.

let me make sure i can find it first. My garage is a mess

Just JBWeld shut the 2 FITV ports on the bottom of the throttle body.

so, with this mod, what is the idle during cold startup and idle?

Re: FITV less TB's
 

my single cam idled at 900-1000 with no iac or fitv. I had a big venom sheetmetal intake
Cold idle wasnt any higher, i just revved it for a minute when it was cold manually.

Re: FITV less TB's
 

I never run iacv water lines and run obd2 throttle bodies or block off the fitv and never had problems with cold idle but I do live in california coldest maybe in the low 40's

I plugged the fitv ports on my obd1 converted 91 civic with JB weld. Stock P06 ECU. Cold idle is 1456rpm, warm idle 760rpm. NEVER any warm/cold idle problems.
