Blow through MAF

Blow through MAF

My R32 GTR smells aweful everytime I change gears (exhaust smell in the cabin). So I Phone up a reputable skyline tuner and he said it's because of my aftermarket bov. (I read a lot on r32 before so he confirmed what I thought)

He recommends going blow through MAF and then tuning or finding oem piping and oem bov.

I want to get a tune anyways, so should I try to find the oem stuff somewhere or go with the blowthrough set up?

[My car is pretty darn stockish apart from HKS green pod thing intakes, what looks like a 3'' full exhaust and a 20 something year old tune from japan with the stock ECU]

check out my newbie intro tread if you wanna see what it looks like

Lol.

So you have a atmo bov atm.

What you want is to plumb it back in.

You don't need to go stock. But stock is good.

I don't think it's your bov causing the fuel smell in the cabin.

Unless it's running so rich that the fuel is jumping out the exhaust and into your window while driving.

Wow. just wow...

If a "reputable Skyline tuner" says blow through MAF, i'd take a guess and say it's not so reputable lol...

English aside.... My guess is they mean "tune using a Map based ECU" so you don't need AFM's.

You do realize on a RB26 the BOV's (yes, there are 2) are under the front right hand guard/bumper. I doubt anyone's changed them. Does is go pshhhh, or sound like the Fast n Furious

Exhaust in cabin (not fuel smell) could be a leaky exhaust or gasket, aging rubber seals letting fumes into cabin.. or is it a burnt oil smell?

The way he calls it is blowthrough as a term lol. Since he tried explaining it to me and i wasn't  exactly catching along whate he was saying he just said call it blowthrough maf. It's probably me not understanding stuff since this is all new to me lol. And the guy speaks french so yeah, he might not have the best english terminology either.

 

The bov are HKS and vents to atmosphere. (Goes pshhhh)

 

Now what the told me is that what he would do if I brought him the car, is move the AFM or maf or whatever the real terms is (the air meter captors things). He'd move them towards the front so that I can keep the stock ecu. That way it would avoid the factory setup that thinks the air is going to recirculate back into the system and compensates with more fuel even though there is no extra air because of the atmo bov. With them up front he'd set it up so that the air being vented out by the bov is nonexistent to the ecu.

 

sorry for the crappy terminology, I'm still learning.

What you'd want is to replace the BOV and HKS mushroom junk with standard parts, clean your AFMs (possibly do a solder fix if it's still acting up when hot), and check your exhaust for leaks.

I for sure need to check my exhaust for leaks.

Now I don't know if I can find the stock airbox, but I'll give it a shot. If i can't what else do you recommend?

The guy mentionned that I need to check that all the original recirculating piping is still there if I am to fit the oem bov. 

I like dtaying stockish so that's kind of a bonus if I go back to oem.

If you can't find an airbox, then I'd swap out the HKS sponge for paper pod filters, and fab up an enclosure. e.g.:

What brand of paper pod filters would you recommand?  Looking around I found this :

Now i don't know anything bout any of this so I don't know if I need the entire kit or just the pods. I'll have to take pictures when I have time.

And that's a sweet looking heatshield/enclosed there. I wonder how it was made. 

Cheers!
