Buzzard I am glad you check me on this because as I read more about the BOV recirculation to the intake manifold it so far seems to only be beneficial for cars that run an MAF sensor not a MAP sensor for the purpose of maintaining proper AFR between shifts. But I am going to keep searching and reading.

Even then I think it only matters if your blowoff is downstream from the MAF, you want the air to get to the manifold if you've already metered it.

Of course the usual "I don't really know what I'm talking about" disclaimer applies

For a MAP ecu vent to atmosphere.

Yeah what he said ^ (glad to see the Legend Gods are still watching over me) :angel: as I am reading more about this it just seems that it will be safer and less complicating in my case to just vent the BOV to atmosphere. It doesn't make sense to redirect to to the intake line pre-turbo because the turbos are right off of the headers. I am not going to delete or change my error though to ensure others do not follow suit and read through this.

+1 My friend has a 3000gt vr4 and it has a MAF sensor. We were tuning his boost controller and decided to pull the hose from the bov back to the intake pipe off to see how it would go. It ran like sh*t. The MAF only calculates for the air that goes through the filter, so when you vent to atmosphere it still puts in the amount of fuel required for the air that is now gone, thus running rich between shifts in addition to making the idle a bit more rough. Of course it is possible to tune to compensate for this.

As far as having a MAP, there's no need to worry about this because it measures manifold pressure. So vent to atmosphere.

Now Telion since you are at this stage (im geussing close to a finished product) will you list how much (to date) this costed :dunno: i think it would be a good idea IMO...

 

[Telion]

lol a good idea would be to know that you will get out of it what you put into it, when I began I set out to do this cheap to prove that it can be done. And as I got into it I learned that anything done on this scale should be done right unless it is expected to be done over, so in hindsight with all the assistance I have had yes this could have been done for about 1 to 1.5k but I chose to go in a direction that would yield less headaches as I increase power. I will say this much though you can go cheap on everything but the external wastegates, the muffler, and the turbos. And I cant even put a price on the welding

 

[Telion]

two more items need to come in then we will be going in for the final welding session after that it is just putting together the pieces to the puzzle, saying a few prayers, and eliminating CEL's that I encounter.

 

[racersonly]

the placement you have shown is fine....heat is not an issue

dude heat is always an issue when going turbo. telion your whole setup is going to need to be completely wrapped with heat shield/wrap, your engine bays ventalation will need to be improved. and you will probably need an even bigger radiator than the one you currently have,its a two core right? a three or four core will most likely be needed

Usually it depends on the size of the turbo or how much PSI is throwing. Telion turbo's aren't that big. He could do fine with the radiator he has, but it's better to get the aluminum radiators.

true for engines that come turboed. but n/a engines usually have i higher compression ratio then turboed engines so when you add a turbo charger you also restrict the exhaust to some extent. that coupled with the higher compression will cause the engine to run alot hotter. he should also think about adding an external oil cooler.

re oil cooler: Check page 41

racers only, I understand that there is a lot to read through but each of these issues have been addressed if you go through the whole thread. I will add some of it to this one page though as it is a lot to go through

-Jet hot coating headers and possibly the downpipe (it will at least be wrapped)
-Turbos get thermotec heatshield blankets

-radiator is an all aluminum C&R racing radiator with a SPAL fan

-hood will be vented over the turbos and is slightly raised already on the sides and the rear
-cooling will be handled by a dual core oil cooler and a stock oil cooler (turbos, oil and tranny)
I plan to route some air to it in a ducting like manner

-Turbos will be both water and oil cooled
-Decent sized intercooler (that will be assited by a water injection system)

-A great deal of attention was paid to the exhaust flow from the headers all through the exhaust

But thanks for lookin out

And as you can see there is still a ways to go

Holy rust spots batman!!!!

 

[Telion]

I dont think that is actually rust it is from the welding process. None of these parts have gotten wet or left the garage since being installed. but I will double check

 

[l4zy415]

Lol I hope its not rust. At least your project is getting there. So were you able to get the exhaust on right?

 

[car2n]

I agree with that that is just the color of the metal heated and then cooled after the welding proccess.

I being reading some parts of your thread for at least an hour and is really going well, specially the header work congrats, I am also in the proccess of planning my header work and wanted to learn from your work that is why of the long reading lol, well just wanted to say that...:thumbsup:

 

[Telion]

Yeah the rear flanges were just welded with the point of the triangle facing up instead of down which caused it to hit the heat shield. I am just going to trim it down so that it does not hit it and raise the shield a little then it is golden Now I need to figure how I am going to tuck the wire harness.I am considering in the valley of the V near the knock sensors and what not.

Thank you the process with the headers went pretty well once I decided to just do them from the ground up next time I will probably go with .065 mild steel though instead of the weld els and thick DOM tubing, but these babyies should last a while lol.

Just another pic in preparation to not end up with a melted wiring harness
