What is the modification necessary? Easy DIY?

 

Besides the battery, I think the main problem with the Buschur Upper IC pipe and the stock air box might be the stock location of the mass air flow sensor, which seems to be relocated more up and to the outside with the Buschur cone filter intake. If you compare where the mass sensor is located in these pictures from the Buschur site, it looks as if the Buschur IC pipe would run right into it in the stock location.

The thing I like about the Buschur upper IC is that it seems to cut out a lot or bends and length compared to the stock tubing (6 bends and 16"), which most other pipes don't seem to do. I'm not really sure how much that matters, but it sure does sound good I just wish it worked with the stock air box.

 

here's a comparison photo of the buschur and the stock pipe

 

Hmm, so if I had the battery in the trunk, then using the BR hard pipe with the stock airbox shouldn't be a problem, right? That would be sweet. Although I still have some concerns about having to do some custom fabbing to fit a Greddy Type-S BOV onto the BR hard pipe... but I think I can live with that as long as I can retain the stock airbox.

PS.: Thanks for the link, EvoTio

 

I would talk to David at Vishnu about the battery relocation, he did it all himself when he still lived in Texas and it was a perfect job. As for mounting the greddy type s to the br pipe I am pretty sure that Buschur could simply weld the appropriate flange to their pipe for you. I believe David Buschur said that you could purchase the upper pipes alone without the 1st gen valve for cheaper. Oh and you might want to talk to this guy, he claims to have the br pipes with the stock air box https://www.evolutionm.net/forums/sh...0&postcount=30

 

I already PMed QuickEvo about running the Buschur IC pipe with the stock air box when I read that post. He is using the Cusco hard intake pipe kit that replaces the stock rubber intake pipe and raises the stock air box up a little, making room for the Buschur pipe to slip underneath the box/mass sensor. I'm wondering if Buschur's intake mass hard pipe will work with the stock air box, since it is cheaper than the Cusco ($200 vs $289), although it looks a little bit too long.

 

not trying to take business away from Buschur but how about this as a solution?

3" Stock Replacement Intake Pipe
Full hard (steel) intake pipe for your EVO8 replaces the stock rubber intake pipe for increased air flow. The MAS end is 3 1/8" dia to match the EV08 MAS and tapers down to 3" inlet at the turbo. The air filter box will bolt down in the stock location. Comes with BOV return tube, Charcoal Cannister tube, air nipple, couplings and clamps as shown

 

Yeah, that Dejontool hard intake pipe is a lot cheaper. The only question is if it raises up the stock air box enough for the upper IC pipe to slip underneath. I dunno, for $140 it might be worth a try Maybe one could slip some washers underneath the bolting points for the stock air box to raise it up a little too, who knows.

 

that could be a good idea with the washers pending that noting gets put in a bind.

 

That looks pretty much exactly like what I'm looking for, including their upper IC pipe. I'll have to find out if that upper IC works with the stock airbox, though. Thanks for digging up this info guys.

Hmm, so if I end up mixing Buschur and Vishnu parts on my Evo, I guess that'll make it a Bichnu ... hehe

lol, you'll be the bastard child evo

 

Buschur may have modified the design of the mini battery tray. When I installed my battery kit I didn't have the intake or cone filter since it hadn't yet arrived. That's when I discovered the interference. Basically all that had to be done to the design was move the battery back towards the firewall about 3/8" and the battery should fit with the stock air box.

It looks like Dejon has some cool parts and cooler prices. I'm eyeballing that 3" no-MAF intake pipe for a conversion to speed density. If you go with Dejon, let us know how the fit and finish is.

 

Yep, Buschur said himself that the upper IC pipe would work with the stock box, however it would be a very tight fit: https://www.evolutionm.net/forums/sh...tercooler+pipe .
Raising up the stock box would also help, but the stock airbox bracket needs to be removed and the stock boost solenoid moved, so I'm actually wondering what would be holding the box in place and how many things would be touching? I might have to give them another call sometime...

 

Hey, did anyone else (besides QuickEvo) ever end up getting that Buschur Upper IC Pipe to work with the stock airbox? I'm still thinking about doing this...

 

For effieciency and power the BR IC piping is unparralel.
