1) DIY MBC................was nice and cheap
2) Intercooler pipe mod = awesome, great throttle responce and spool up
3) Hand porting the o2 sensor housing at the exit and the exhaust manifold at the intrence and exit a bit.......pretty good again some added feeling in spool and responce.

4) Soon to be done Thermowrap the entire downpipe*
5) Soon to be done Make a aluminum box around air filter*
6) Soon to be done Re-wire stock fuel pump for more fuel*



*My all time favorite DIY mod with the biggest improvement would have to be re-routeing the IC pipe that went over the VC to routeing it with 2.25 inch around the rear of the VC.

Haven't added the screen yet but I have made a box around the air filter to eliminate turbulent air striking the air filter.....here is my responce form another thread:

OK, did a lil soemthin somethin today, I made a semi closed box around the air filter effectively blocking incoming turbulant air from the front of the car and the radiator fans, here r some observations I noted.

1) On coast down my o2 voltage will quickly get to .00-.01 volts everytime without a doubt even at 100mph+ so no turbulence is hitting the filter screwing up MAF volatge.

*Before my car on coast down would normally only see .07 - .15 volts during coast down (lifted throttle) and take longer to get there. Also now there seems to be a strange sense of smoothness about how the power is put down.

**I think thios is also going to improve gas milage, that wastegate gass on coast down cuzz injectors should be shut down.

charlie, post some pics up of your box

 

[charlie2020]

LAMO its a Jordan shoe box for right now, basically until I get some sheet metal.

 

[sleeping 91ser]

my friend did the same thing your talking about charlie, I think it helps a little, he did it on his eclipse, first he made a template out of something like a shoebox I guess than cut some sheet metal to use, it worked fairly well

 

[blairellis]

hahaha, nice i guess that works...is this the ghetto mod section? jk bro.
