ok im looking for easy bolt on performance mods. is changing the pullys a good mod?

would i have to change anything or can i just swap out pullys and belt?

 

intake or plenum spacer are a good and easy start. you get noticeable increase in power and it is easy to do

 

i have an injen intake already. so you are saying a plenum spacer is should be my next mod? will this void warrenty?

 

intake voided your warranty. who cares.. lol

 

dont waste your time with pulley's they're not worth the money or the hassle of the install. and wont gain you any noticeable power.
-GP-

 

As far as warranty goes, I believe what ever part you replace on your car the warranty is voided for that specific factory part. Now if the maintanace staff can prove that your aftermarket part caused other engine components to fail or work properly they may be able to void the warranty for more parts. That is how I remember it.

 

so plenum is what im getting...... thanks

as far as warrenty all i have to do is remove mods before i take it in lol......


now do i get a new plenum or just the spacer?

 

Motodyne Plenum Spacer is what you want to get. Thats next on my list

 

If you want to do pullies, all you need is a new crank pulley and not the whole set.

you can either get one with the stock size, or underdrive. the difference is probably 1-2HP, but with the stock size you can keep using the standard belt size.

i have the UR stock size pulley and i felt noticeable gains in the low-mid range, and to be honest the gains felt similar if not equal to what i felt with my 1/2" spacer.

 

+1

I have the UR underdriver set, and I noticed low-mid range gains, but nothing to
say OMG!!. The UR crank weights like 4-5 lb less than the stock crank.

 

thanks guys

i think i will get the spacer first...

 

If you have a 2005 & Up 6MT, get the MREV2 with the Spacer.

 

Def go for the proven and cost effective mods first like md spacer/mrev2. The stock size ur pulley set was one of my last mods. Honestly I haven't noticed much performance increase, but strangley I have experienced less nvh, which is great, but I was expecting the opposite result. Make sure the crank pulley has a pressed steel insert and is installed correctly and carefully.

 

+1 those should be your starting mods and go from there...intake, spacer + MREV, sway bars, etc. after your bolt on's a good tune will be a great "mod" as well.

 

thanks guys...

i have an 05 auto so all i need is spacer right?

or does the spacer go with mrev2?
