What's the importance of this part?

When I was reassembling the motor today, i came across that the plastic part broke off. It also looked like it was not hooked up right anyways but i noticed there are two of these on a 87 non turbo model. I'm curious if i continue hooking the rest of the motor and get this part later( possibly even start the motor without it)? Thanks |
Looks like the fuel pressure VSV (vacuum solenoid valve) can’t be certain with out tracing the vac pipes to where they terminate. Unfortunately your attachment doesn’t increase in size enough to check that out.

Found it Link, I’m not absolutely sure, but I think it increases the fuel pressure at start up, by detecting low or high vacuum. I know they are made by Denso and cost a fortune from Toyota.

id hook it up.. lol
|
When I did my hg I broke the vsv for the butterfly in the intake manifold. I ended up getting one off a vibe of all things over at twosrus near me. Toyota has not changed the plugs they use over the years so you should be able to get one fairly easily. The only thing you may have to do is get alittle creative with the mounting of it.
|
wtf is a vibe.. :barf:
|
Its a rebadged matrix. Visually it is a pontiac but it is really a toyota. A vibe GT actually has a 2zzge with a 6 speed which is where my motor came from because I misshifted the celica a while back.
|
yeah... the plastic pieces are broken off... i was wondering if i could just hook the two together and bypass it...
But if the weather is nice like it was today im gonna go hunting... |
If the Vibe won't do (just because of the donor's name) then get a VSV from Mercedes... they're still half the price of a new one from Toyota for the Supra.
|
lucked out and there was on wrecked supra in the very back of the salvage yard
:D hopefully i can get it running today Thanks for your help guys |
I know this is off topic but if you think the vibe is strange then look into what powers a lotus elise.

Lotus has used Toyota components for a very long time. They use parts from a number of other manufacturers too. Their chief designer designed the MR2's suspension and the company's lab worked on tuning it... It's argued that they also played a great roll in the initial frame work of the vehicle (Toyota needed to learn the tricks to build a mid engine car that they could get on the market fast and without a lot of their own $$$ going into R&D... and they just happened to own controlling stake in a company that specialized in it.)
Lotus uses Yamaha designed heads (same as the 2). Toyota owned controlling stock in Lotus for a long time and as such they both contributed to eachother's product development and implementation. Supposedly Lotus was also responsible for the fine tuning of the Supra's suspension although I don't know what generations and I've only seen it mentioned a couple times. |
And it seems that the next Elise will basically be the ft86, which is the car everyone thinks will be the next supra or as close as toyota will get to one.

The early Elise had a Rover K series engine in it. I think the guy who designed the head gasket must be the son of the guy who worked out the Supra cylinder head torque settings. It’s more famous for blowing head gaskets than the Supra. It’s also used in the MG F, Lotus Elan and MG ZR, which is a shame really because they are not bad cars. The design was total wrong, the head aligning dowels where made of nylon, the head bolts ( about 12in long) go straight through the ally block and screw into a ally oil rail underneath. The recommended upgrade is metal dowels, thicker designed oil rail and a gasket as used on the Land Rover. Unfortunately when they go, they normally leak between the combustion chamber, oil and coolant resulting in big end failure as well. I’ve striped one down and done the mod, only lasted a 2 K miles then blew again. Goggle Rover K series head gaskets and you’ll see what I mean.

One of those went bad in my Supra and he would not run unless the air intake was open full. Once a few one was ordered and received he was running again.
