I have been researching a 2 wheel low kit, and I have come to a dead end. I have found that some TDR members used a "Nippondenso" EGR vacuum switch from a Honda Civic, but I cannot find a part number anywhere. Searches on auto parts websites have yeilded nothing. If there is anyone who has made their own kit with this switch or any other design please post it here? Thanks!

 

I made my own going the 4-way valve route. Positive actuation of the CAD. Not just blocking off the vacuum signal.
Parts consisted of a 4-way valve, a few feet of 6 mm hose, (because the valve came from Europe) 3 elbows, 3 nipples to join the vacuum lines to the 6mm hose, 3 grommets and 3 little red caps.
PM me your phone # if you want more details. Mike

 

Check out this thread. He uses it a lot, and it works well.

 

That thread was helpful, but I still could not find a "vacuum switch/solenoid" for an RX-7 for less than $75 on the parts stores websites. Any ideas on a part number?

 

Part number is AESA127....does not have a company name on the solenoid...not sure what year the RX-7 is...has the rotary engine in it...I'm sure these fit a lot of different vehicles.
