Default What Size/Kind of Pulley?

I have a 2000 SSEi and want to buy a pulley for my car today online. Looking at zzperformance.com and want to know if there is a certian one that I should buy. Also how hard is this to install? I think I need a pulley puller too right? The only mods I have right now are an intake. Is there anything else that I should do before the pulley. Thanks, Brad

If I get a 3.4, roughly how much power will it had. I am hoping that it will be a noticeable difference?

The usual swap is to a 3.4. It says it adds 25 - 30 hp. Believe me it is a noticeable difference. Instead of running around 7-8-psi boost I'm putting the gauge over in the corner at 10-12 psi

The best place to start before the pulley swap is the Cold Air Intake,then the exhaust.

The exhaust would be a matter of preference, Most of us around here run a Magnaflow F-body hi-flow muffler.Make sure the muffler is a single in/dual out.

When changing the pulley,you have to run one range colder plugs,so now would be a good time to do a tune up. Autolite 104'* or NGK TR55'* are suggested,gapped at.055. O2 sensor,plug wires and assorted fliters.

A 3 jaw puller is not a good idea. A special puller is used to remove the pulley,since the puller is also used to press the pulley back on.
If this is going to be a one time swap,the puller can be rented from either Intense racing or zzperformance.
Also,you'll need a 715 belt to make up the difference after the swap.

I got my pulley and rented the puller from zzp and believe me,it made a world of difference

Maybe one of the gearheads can chime in and add,if there is anything I missed.

Changing to a colder thermostat will do nothing until you change the PCM.

Right now i have a 3.4 , with a FWI (fender well intake) and colder plugs (TR55),and a high flow cat.

And i run the stock belt. , no KR.(check your boost gage to see if your boost go higher, you will know if your belt slip, it should go near the end of the yellow part)

The best is to have the car scan after the install to see your amount of KR (knock retard)
due to a smaller pulley, but you can be fine with a GOOD intake and colder plugs.
(You need to protect your filter from heat, fender well intake are the best.IMO)
A good heat shield can do the job too.

Dont forget to reset your PCM , (unplug your battery while you change the pulley and replug after, it should reset it)
Also, get the car a bit warm to help remove the pulley. And let it cold down to put the new one, it will be easier.


I went from [email protected] to [email protected] with the 3.4 pulley, and [email protected] with the high flow cat.

And like dbeast420 said... youll love the torque (save money for new tires)


Let us know how it run.

Once youll begin, it will never end

i have no experience with forced induced cars, but i wouldnt really consider getting a new muffler opening the exhaust all that much..you would benefit much more from a high flow cat and keeping the stock muffler than you would a muffler change.

Keep in mind the Fastest Street driven Bonneville is running a stock exhaust

When it comes to exhaust I'd say start at the front and work your way back. (headers, DP, Cat, Res., Muf.)

Ok this weekend I am going to be putting on some colder spark plugs I just bought and making a fenderwell intake. I should be alright to get the 3.4 pulley then right? Do I actually NEED a 180* t-stat? Thanks, Brad
