yeah, I woudn't want the elements to have a direct shot in to my engine - then again I'm in Ohio. Also, whare are the chances of small animals nesting inside your engine bay? Thats all I'm going to say about it...

Motordyne Plenum Spacer vs. Kinetix Intake Manifold
Motordyne Plenum Spacer vs. Kinetix Intake Manifold
the 1/2 inch one is the way to go if you are going to get the motordyne plenum spacer. its the spacer designed for most power gains and an audible difference. if i get the motordyne spacer, i will get the crawford strut bar (i dont want that ugly hood STB)
so if you do the math, it is 200ish for the motordyne plenum spacer shipped + 170 for the crawford STB = 370. but then i figure if i am going to spend 370 on this, i might as well shell out another 300 and get the kinetix racing intake manifold, which should be priced around 650. i think me and you are looking at all the same performance mods. my car is bone stock, asides from aftermarket wheels and tires. i plan on sticking to a NA setup, because i just dont want to shell out 7000 for a turbo or supercharger installed.
so i figure....
1. kinetix intake manifold - 650
2. injen cai - used for 100, new for 200
3. injen super ses - new for 750, used for 500
4. kinetix HF cats (there is a gb on these and the new intake manifold) - 325
5. UR crank pulley and belts - used for 200, new 350
these parts are easy to install, so at a shop, install costs wont be too high (not 500 install like with headers). altering the upper and lower plenum is what allowed the 05 350z to make 300 hp. the kinetix intake manifold, although NA dynos arent out, i think it has potential to create a 20 hp gain when used with mods 2-5. this 20hp gain will be in addition to the power gained from mods 2-5, so i am thinking somewhere in the ballpark of 40-50 hp total with using these mods. if i am right, as the kinetix NA dyno will be released tomorrow, that is around a 20% gain in power for around 2000 bucks (if you buy the parts of the classifieds).
i dont know.. i might be rambling... but if those mods cant create a 30+ increase in hp, i will just get the motordyne spacer (1/2), crawford STB, jwt popcharger, some TD exhaust, and some HFC. i should be able to get all of that for around 1000. power gains should be around 20-30 hp, decent for the price. its times like this when i wish i had a supra tt.... if you invest 2500 into the 2jza engine... you would be throwing down more than 500 horses. truth is, if you dont go FI, you cant get any real power gains. hopefully the kinetix intake manifold dynos will prove me wrong

that combination made 245 whp and running extremely lean 14.0-14.2 also it didn't feel as strong as putting a plenum spacer. You'll need a ECU reflash if you want to gain more HP but i seriously doubt you'll get 30-40whp from the mods you listed. as far as nissan getting 300hp for the new Z that's only a bump of 13 hp from the crank. when you think about it thats about what the plenum spacer is doing already. i know the hood spacer not for everybody, but i think it looks great and i plan to track my car soon. good luck on your future mods.

i agree the 1/2" is the way to go....but in the other thread the Motordyne guy mentioned that the 1/2" spacer only put out like 1-1.5hp more than the 1/4". for that little performance ill keep my hood stock. also i dont care about the louder growl

Virg,
As far as driving impressions are concerned, what kind of hp increases do you feel? Any losses down low? My primary concern is to get the 1/2" spacer b/c of the hp..and noise

i like the 1/2 in spacer. but, i want to keep my oem strut and i dont like how the hood looks with the spacer on. i just might go with the 1/4 in. but i was wondering what the
growl" sounds like with the 1/2in. any audio clips?
do we need to use that spacer with all hoods? i have the kaminari CF hood on order and it is vented so im not worried about engine bay temps.

i personally had the aam spacer and i found it to be a good short term solution but not a longterm one. i kept having to check for leaks. and it ended up killing me.
go for gold and buy a permanent solution -- crawford or aps ... anything that is one piece design... i would mention kinetix but its plastic. too many people have cracking issues
