BHG --> NO More

[JSHeinrich]

I'm just extremely happy and needed to release my joy. Yesterday was my birthday but more importantly it was the day I got my supra up and running. One of the best birthdays in awhile. It is running real well right now.

It has been about 6-7 months down. The weather is great so that makes me even happier. PICS COMING SOON!

I also wanted to thank the whole community. Several people helped me out, too many to name off hand. I had a lot of newb questions and they were all answered quickly and with the effort of teaching me. This community is a great thing. Thank you all....


P.S. My VSV thingys on the bottom of the intake manifold, I have one bolted on one of the lower bolts but I don't know where the one toward the front bolts onto. If Anyone has a pic of this for me that would be great.

congrats...awesome feeling isn't it?

VSV's...those annoyed me. i bolted on my intake and then realised one wasnt bolted on along with it.

NA or turbo?

 

[conundrum07]

Heh, I just ditched the VSV's. Along with removing the PS idle up valve and EGR junk it makes the vaccum lines much simpler.

Congrats on getting it fixed! Enjoy it till ya break it again :evil2:

why? i live in fl and have not had a fuel vsv or egr vsv on my car for almost as long as the 6 years ive owned it.

same with a lot of my friends... no problems here. some of the things toyota did on the car are simply overkill.

 

[jdub]

Good for you...I was mistaken that the hot start fuel pressure up VSV was a desired piece of equipment.
Must be nice to be so much smarter than the engineers that designed the EFI system in this car

come on man get off the high horse for a second and understand that not everything toyota put on the car is NEEDED or for that matter CORRECT.

must be just as smart as those same engineers who torqued that hg right? :nono:

that vsv can be removed with next to no ill effects in my experience on probably over 20 cars of removing it and being around those cars continuously after.

does it help? im sure it does..... if you take it off are you going to have problems hot starting the car? maybe but more likely then not, no.

 

[conundrum07]

Eh, I never had any problems with removing it either. YMMV.

Hmmm...and I'm the one on a high horse because I know what it does? Do you have a clue as to what that VSV does? If so, please fill us in...your reasons for removing it and the benefits of doing so would be good.
Got news for ya, the VSV is a cost...Toyota would not have put it in unless it was needed.

Bet you're running an AFPR and some sort of fuel piggyback...correct?

Not to mention, removing the EGR (the only reason to remove the EGR VSV) is one of the dumber mods one can do to this motor.

Just because the mob says it "ok" doen't make it so slick...I've had too many guys try to hand me the "in my experience" thing.
Sorry, but it really doesn't cut it unless you can back it up with knowledge of how it works

I will concede that the Toyota torque spec for the head bolts was too low...other than that, this motor has very few problems. That is unless the owner decides to screw with it and start removing parts of the EFI system just to "clean up" the engine bay :3d_frown:

 

[Mr.PFloyd]

its not just these cars... everyone removes EGR systems on all sorts of cars.

 

[jdub]

Yep...they sure do. Even though the EGR helps reduce cylinder temps thereby preventing detonation, has zero effect on increasing HP, and increases production of one of the most noxious pollutants a car can produce. Makes sense to me :icon_conf

 

[JSHeinrich]

oh boy...everyone just calm down...haha

I left the vsv's connected. One is bolted to the manifold and the other is kinda just hanging around.

congrats...awesome feeling isn't it?

NA or turbo?

Sure is a damn good feeling, I'm just still sketchy....I'm nervous until it is running for a bit and does break.

It is a turbo

 

[Figit090]

*doesn't. i know its a supra but try not to think that way

cool. yeah...i wish i had one. (turbo)

you'll get over the sketchy part...eventually.

 

[jetjock]

Ugh. Auto makers do not put things on cars that aren't needed. Forget the tech aspects, it increases their costs. Not just in material but in engineering costs. That particular system isn't just some wires, tubing and a valve you know. The code for running it had to be engineered. All that cost money. Not to mention recalls and fixing things after a car is released are hugely expensive for an automaker. Last I checked Toyota was still in the business of making money. You may be able to run without it but for sure it's there for a reason otherwise Toyota would have put the money into it's pocket. I won't even get into EGR. I'm far from an eco-nazi but it's not as if the effects of NOx are some kind of unproven global warming ooga-booga.

 

[LilMissMkIII]

Congrats mate!!!!!!

*happy dance* for you

 

[Z'mnypit]

Cograts man! It is a good feeling. Just completed mine about 2 weeks ago. It was only down for a week though....

 

[Kai]

I just thought i'd stick my oar in for a second....if ditching the EGR is so bad - why did none of the European models have it?

 

[jdub]

Because it was not required...USDM ECU's are "tuned" to have the EGR. If you delete it, you "should" get a JDM ECU (at least here in the states). That still ignores the amount of NOx you will be contributing to the air quality

*sigh*

im not going to fight with what you THINK happens when i have had first hand experience with what DOES happen when these things are removed. HOWEVER i would like to say that i dont consider it taking 1 second longer to start or 2 cranks more to start being a negative effect. so maybe we are speaking on the same terms just different languages.

as for positive effects? its about 10 vacuum lines simpler and i dont have a rats nest of crap under the intake manifold anymore. i reduce my points of failure 10fold and yes have a cleaner and easier to work on engine bay.

what i do know is i get in my car which has no vsvs on it, no egr, NO FUEL MANAGMENT AND NO AFPR, and it starts right up under what i would consider normal starting/cranking time. meaning under 5 seconds.

so take that for what its worth but i definitley dont appreciate being talked down to by someone who thinks thinking OUTSIDE the box is a bad thing. just because YOU dont think it should be removed does NOT make it a sin to remove it.

 

[jdub]

Well Ideal...I see you're still sticking to your "experience". Well that's fine, even though you're wrong. Do as you will, but just because it happens to work for you doesn't mean it WILL work for other cars in other parts of the country. I don't have to "think" what happens, what the VSV/EGR is for, or how it works...Toyota figured that out long ago.

BTW - you'll know it when I talk down to you...it will sound like I'm talking to a child, using very simple words. Keep in mind, you escalated with the "high horse" thing...if you want respect for your opinion, you have to respect the opinion of others. Especially when you're wrong
