Hks Hi-power Ti Exhausted - No Doubt This Exhaust Is One Of The Best
Ur Crank Pulley - Hear Good Review On Them Def Get It.

Nismo Cai/injen Cai/stillen Caib - Which One Is The Best And Sound Better???

Md 5/16 Spacer, Mrev2 ---or---kinetix Plenum, Hfc - Which Is Better Set Up???

Kinetix Hfc ---should I Get This Also If I Go Md5/16 With Mrev2 Set Up, Would It Be Much Louder If Anyone Ever Have This. How This Going To Effect My Hks Hi Power?????

 

hks, fast intentions high flow cats, stillen airbox, mrev2 OR 5/16 spacer

the reason i say or is because if you run both you will run lean since youre nonrev up. mrev2 alone will have slightly better gains than the spacer alone but
imo not a big enough difference to justify the difference in price.

however, you can get mrev2 and the spacer if you get a tune...

then again...you should always get a tune anyway to maxamize the output of your mods...but most people dont...

fast intentions or crawford high flow cats...kinetix sucks imo

 

Thanks - saved me from typing!

Hks Hi-power Ti Exhausted - No Doubt This Exhaust Is One Of The Best
... for high rpm HP with a 6MT, maybe. I'd recommend you do further research on what mods you're going to do on your auto trans coupe.

Just my opinion....

 

I already have hks hi power on my car that why i said no doubt is oen of the best lol. but the other, i still wondering on what to buy since i want to go NA but then again i thinkin about a used vortech or turbonetic...wath do u guy think. NA if i want to be safer rite...

 

truly a G's Hero

 

Yes on HKS,
Not sure about pulley
No on CAI especially with MREV, plenum; that is what I hear from someone.
but a short ram is ok.
HFC is good, but it get really loud sometime. i dont know about this particular brand is going to be loud too.

 

Start off getting the:
1. Motordyne 1/2" Spacer - Reason I say 1/2 instead of the 5/16 is that because of your runner length, etc.. (i dont want to go into details) is because you want your intake & exhaust combo to go together.. and its easyer to aim for the upper RPMS in our case here..

2. Stillen CAI w/JWT Cone Filter: IMO this is all personal preferrence but Tony and I both seen power loss from NISMO CAI aka AEM CAI and Injen CAI.. Stillen CAI uses a cold air box and keeps the filter in a enclosed area to keep dirt from comming in.. reason i use JWT is because i like their filter design.. you can also get a z-tube if you want the motor to be even louder..

3. HKS Hi-Power Ti looks badass but if you want true performance go for IMS Exhaust.. their exhaust diameter is the most reasonable and it sounds pretty good as well.. if anyone still remembers what they learn in physics class.. (

quick example: get 3 straws.. 1 regular one, 1 boba (bigger) straw, 1 toilet paper roll

The regular straw will represent the stock exhaust.. you can breath through it just fine but when you power walk you'll be out of breath and pass out..

the boba (bigger straw) will be our IMS exhaust.. breath through it very well and you can power walk or even run just fine

Toilet paper roll will be our giant 3" rocket pipes... you're about to fall over breathing normally.. but if you power walk or run it you'll be yeah u get the point

i know its a bad example but its just a quick one.. this applies to both intake and exhaust.. this is why a 3" pipe wont work better then a 2.5" pipe.. no velocity no go... the whole point of an intake and exhaust system is to get air in and out of the motor ASAP at a specific range of RPM.. now just apply some sense to this.. you have a 3.5Liter engine.. if u break it down thats 1.75 Liter per bank.. do you really need a 3" exhaust for a 1.75 liter... -__- some of you guys laugh at 1.8liter civics with 3" exhausts but you yourself run a 3" exhaust on 1.75 liter (actually you run 2 lol)

anyways.. save yourself the money on the pully and high flow cats and go buy a ECU and tune it after the intake and exhaust mod =)

toilet paper roll

 

you do not need the pully.. it wont be worth the $ as far as everything goes.. reason most MT guys get pullies is because it gives us alot better RPM response.. (if you guys are like me you hate waiting for the RPM to drop back down)... you drive an AT you wont notice a difference with the pully on or off.. just save yourself the trouble and save the money..

high flow cats are good but careful most high flow cats are very poorly made.. (why not just run no cats at all)..

IMO after the intake and exhaust just save the money and go eat a expensive steak dinner

 

good na set up does not exist........i had a similar set up and was not satisified with the gains for the amount of money that i dropped.........listen to me and save your money for a turbo, its worth it in the long run

 

whats the IMS exhaust?

 

I would argue otherwise. Did the UR pulley on my 5AT and found the engine to be much livelier after it was installed. I still had the same effect of RPM's dropping more quickly and improved response.

I wouldn't recommend doing it purely for power gains. I gained 7 whp at peak, and the gains are linear, smaller gains at lower rpms, larger gains at higher rpms. But for drivability and response, it was worthwhile.

If you're going to do the other mods, do an ECU reflash and look to see about swapping your rear pumpkin with somebody who has the 6MT. The 3.357 to 3.538 swap is very worthwhile, particularly if you're NA.

 

If you are the auto then i doubt you need the 5/16 spacer with the mrev it doesnt do much for the non rev up motors so i would drop the MREV.

I would stick with the HKS exhaust, injen or nismo CAI, i would say injen if you want the most power as nismo is going to be a little bit more "engine friendly". If you live where it rains alot it is worth it to buy the AEM bypass valve for your CAI so you dont clog your filter in rain and end up water logging your motor. Then the 5/16th spacer and get the fast intentions or random technology HFC. Kinetix doesnt make the best product in the world in my eyes. I wouldnt both with pullies until you go FI, its not really worth it in my eyes. No one has really seen results on a dyno, but it should add some kind of power in the lower ranges since it takes less mass to rotate. Anyways hope this helps a little man. Keep us updated on what your going to do!

EDIT: The 1/2 spacer is to much at first unless you have some kind of piggy back system to adjust your air/fuel ratio. Without one you will be running to lean....get the 5/16 on the 5AT better gains anyways.

 

after reading on all the comment of G35 veteran, i deicide to drop the mrev2

so ima get
hks hi power - already have on my car
jwt cai w/ztube
crawford plenum
crawford hfc
ts ecu reflash

last things, is header,...i heard good things about STRUPS from AAM website states that is the best header, i cant affort crawford header since they 1k. what do u guy think...how much diff can it get if i also get header, since header are so expensive to install,

how much whp u think those set up will add up to?
