there were whitish salt like crystals under the coolant cap when i opened it.....my exhaust smells like bus exhaust since i got rid of the cats....what particular smell should i be looking for, burned antifreeze? Thanks for the help....im gonna run it today for a while after I fix the position of the wires on the MAF, and see how it goes.

 

oh, and i scheduled a dyno run for march 23rd at 9:30, so ill scan the sheet and let you guys know the #'s

 

The exhaust will smell sweet if your burning antifreeze. The crystals by the rad cap are probably there from the fill up. If it leaks a little at a time you often don't see the coolant on the ground but when it dries from the leak it will leave the salt behind. I think it's just air, give some it time. Can't wait to see your dyno.

If you have larger injectors, ur MPG gage will be off the percentage that they are bigger than stock.

ive tested the gas mileage it seems to agree.....im getting over 35 miles per gallon on the highway.

 

I cant believe your kit didnt come with a BOV!

I would get one asap. Just have a welder shop weld it onto the piping right before the throttle body.

 

Sounds really cool...congrats!

There is a dyno day in South Amboy Saturday. Check the Northeast section for the info!!

Looking forward to checking out you ride at ATCO.

 

That woo woo woo is the sound of the pressurized air in your intake/IC forcing its way back out the compressor housing of the turbo. It's called compressor surge and it's a bad thing. Greddy does not include a BOV because in Cali it's against the law for a car to expel any liquids or gasses (except exhaust). In my opinion a bov is an important part of any turbo system. 5 or 6 psi is not a little, maybe comparatively it seems small, but that’s a large volume of compressed air forcing it's way out the wrong way and damaging the compressor and turbo shaft. Ever try to go the wrong way through a turnstile? Heh, It does not work. And sure maybe you can live without it, but it's bad. It's like smoking tobacco, it's not going to kill you the first time, but it's going to get you eventually. I would drop the cash on a BOV unless you want to spend money on new turbos down the line.

Also because the turbo is slowed down it takes a lot longer for it to spool back up and build boost after you shift, slowing you down even more.

 

hey bruschijr,

did you take off your oil pan to drill? for a oil return line???

as far as installing a BOV... should he route it back to the intake???cause i heard that the maf sensor will go into shock if air is atmosphericly dumped and car could possibly stall...

 

i'll also vote that you get a BOV installed. you're slowly killing your turbos.

also, if you did blow the head gasket, you'll see white smoke under the hood (coolant burning and leaking) around the head gasket area

 

the greddy kit i got had two pre-drilled holes, so i didn't have to have anyone drill it..... As for the coolant issue, it seems to have settled after a fill up and a half...guess it was just air bubbles...and I have the Greddy type-s BOV on order, and getting my spark plugs installed in the next couple days....i heard the BOV should be installed before the MAF and after the IC.

 

The greddy kit comes with a already modified oil pan, it's very nice. This is one of the biggest reasons I went for the greddy kit over the vortech.

You should install the BOV before the MAF so that the air that is vented will not be measured by the maf.

 

do you know if all BOVs are illegal in CA? do superchargers need BOVs to avoid your "tobacco" analogy?

 

its not that i don't believe you but i went to greddy site and under the 350z turbo kit this is alls it says:

Dual Bolt-On Turbo Kit - TD05H-18G - includes 2x cast-iron manifolds, 2x external Type T wastegates, e-manage, 4x 440cc injectors, 2x Airinx AY-SB, piping and necessary hardware

unless the oil pan is considered necessary hardware???
also what about a new gasket when removing the stock oil pan??
does greddy supply a new one???

 

The oil pan is pictured in Greddy's installation guide. Look under the section "Oil Pan Installation"

http://www.greddy.com/prodimages/350...20Part%201.pdf

 

I don't think they would consider it a bolt on kit if they told you to pull the lower oil pan, tap and weld it for oil returns, and then reinstall it.

The lower oil pan does not use a gasket, just a bead of grey silicone to seal it up.


I don't think the law flat out says that a BOV or bypass valve is illegal. But it's very broad in saying the can cannot expel anything abnormal. I am not a resident of california so I do not know, I am going of what I have heard. And the automotive industry keeps thier eye on california emissions laws simply because they are the most strict.

A supercharger uses a bypass valve that will bypass the blower under vacume. Bypass valves do not vent anything into the atmosphere, and some blow off valves are designed to function in the same way.

This one you can use to direct the air back into the intake.


This one you cannot.
