==MODS==

* Ghetto Airbox

* Unorthodox Racing Underdrive Pulley from Greg V @ Mossy Performance

* EGR Removed, except for that part that plugs into harness (to avoid safe mode).

* Weight Reduction: 249 lbs
Gutted interior, among other things..
Inspired by fluid1mobile. It's ugly, but it's a lot quicker now.
Wondering how something comes apart or is held together in your b15?
Ask me.. chances are I've probably taken it off !

* Bypassed Coolant to Throttle Body

* Gutted Pre Cats in Stock Exhaust Manifold

* Gutted Main Catalytic Converter

* Knock Sensor Relocated & grounded

* Pacesetter Short Shifter #01-0422 from mach1car.com. $69.95 + free shipping.
Install? All I can say is after this you'll be Intimately familiar with the underside of your Sentra! Read the excellent write-up by 1SentraNotEnuff, has great pics.

* generic Straight-Through muffler; 5.5" round canister x 14" long, single slash cut tip. kept factory resonator (previously I tried gutting the stock muffler; that was a big mess, and was still restrictive as hell)

* Red Line MT-90 gear oil - really smooths out the 5-speed, but still not as slick as a civic or miata tranny.


==MISCELLANEOUS==

* Borbet Type B 15"x7" wheels + Yokohama Avid T4 195/50-TR15 tires

* Momo Monte Carlo 320mm leather steering wheel + Hub Adapter #3514 from www.ltbmotorsports.com. Tip for removing airbag... Torx #30 Tamper Resistant (hole in the middle)... or Dremel cutoff wheel like i did..

* PCV Oil Catch (gurov's DIY ~$20 catchcan)
But plan to bypass PCV completely to eliminate blowby into intake @ WOT .. by using bigger catch can & blocking off PCV to intake.

* Removed Air Conditioning.
This is moot now, but much prior to removing AC, I Disabled Automatic AC on Defroster

* Trimmed Throttle Cables


==TO-DO / WISH LIST==

* -DONE- phenolic Spacers for intake manifold & throttle body? I've heard of some nice gains on other vehicle makes. Also an excuse to take the intake manifold off so I can port it.
(installed Outlaw Engineering Thermoblock spacers, port-matched intake manifolds)

* Lightweight Flywheel & HD Clutch - gonna try to do this first so don't have to take apart exhaust twice later. Anybody got links to good Write-ups on replacing flywheel & clutch on a QG18 ?

* Header - probably HotShot + a couple of O2 sims to keep codes away.

* CAMS!!! + Springs, Retainers, etc... - Come on JWT!! (sign Petition here).. make Cams for our QG18DE and we will BUY them!

* LIGHTER rims - my stock 14" steelies with 185/65-14 tires only weighed in at 30 lbs! I want 15" rims & 50 series tires that are LIGHTER than That!
(4/114.3mm bolt pattern, 66.1mm hub bore) Check out www.wheelweights.net for the scoop on Light Weight rims.

* relocate Battery to trunk - are Optima batteries worth it? I guess that would eliminate a plastic box and having to vent it.

* Carbon Fiber Hood - Who makes good CF Hood kits w/ complete hardware for the QG18? Priorities to me are good Fit and easy Installation. Any owner reviews/suggestions would be appreciated.

* OBDII code reader - probably Actron, $150 at Autozone. It'd be nice to be able to read/erase codes without bumming a reader from Autozone every week, which is how often my EGR Block-Off throws codes. Are there any affordable "Consult II" ones? I've heard an '02 QG owner advance his timing at a dealership with a Consult.

* Exhaust - hmm.. prolly a full Stromung system, and replace main catalyic converter with downpipe.

* Suspension - I wanna lower it, so prolly Tein coilovers with adjustable height. Beefier front Stabilizer Bar. Does anyone make a REAR stabilizer bar for the QG18? And put in aftermarket bushings.

* Strut Tower Braces - front & rear. Does anyone make Rear Strut Braces for the QG18? If not, I'll have to fabricate one.

* more Weight Reduction - if my car can run without it... it's comin OFF!
There's still a lot more stuff to go!

* maybe a chin spoiler on the front like on 350Z. maybe a wing on the back - something different, maybe low Nascar-style like on Chev Monte Carlo SS

* pass Calif Smog Check in Oct 2008? I'll be keeping my oem stuff in case I can't find a smog tech I can bribe.


==SPECS==
* Top Speed: 122mph @ ~5750rpm 5th gear
(~55 deg F. Elevation=3000ft. Apple Valley, CA 92307)
* Dyno: N/A
* Curb Weight: 2355 lbs (estimated)

Sorry for the repeated thread revival, but I must ask:

How has the EGR removal and OE Spacer combination worked out for you? How long/how many miles have you had this combination done?

Thanks for any info.
