currently have the pop charger and nismo cat back system...looking for more power for decent price....under $1,000

whats next? plenum spacer(5/16)? unorthodox pullies? hi flow cats?

looking for pretty basic install and reasonable $$

thanks...sorry if this has been asked before

 

YES, YES, YES. IMO these three mods itself are the best bang for the buck. These are my next mods!

 

those 3 should be your next, best bang for guck on na

 

replace HFC with Testpipe. Keep your cost down but get the same hp gain.

STRUP test pipe is the one.

 

MREV-2, 5/16" Spacer.

 

Be careful with hi flow cats or testpipes with the nismo exhaust. Its very loud and drones. I am currently looking to replace the nismo exhaust with a quiter exhaust

 

I gain 17 whp with mods below and only cost me $800. As said before spacer, pulley, cat-deletes are the "Best Bang for Buck" mods. I perfer the cat-delete over hi-flow cats due to cost. If you're worried about emission passing than go with the hi-flow cats.

 

I have Popcharger, Nismo cat-back and 5/16" spacer (MD) I dynoed with 266.6whp/250trq. Thats all for performance mods. The spacer is probably the easiest to install out of the 3 that you mentioned, Pullies are a pain sometimes and taking your cats off will be a pain unless you have go go gadget arms lets say, but I did my spacer in an hour or so and my friend and I did his Mrev in about 1.5. I have nice a/f also, heres a link to my dyno results.

P.S The sound is pure sex IMO

 

i love the nismo sound....and id love to get it even louder but not loud to the point where it sounds like crap....i think im gona do hi flow cat...i had the RT hi flow cat/downpipe and removed my resenator and put a straight pipe on my last car as my only exhaust mod and it sounded mint

this may be a stupid question but wat is MREV?

i def am going to do the 5/16 spacer soon....and the pullies i want to do but have to find someone with a puller

also thinking of getting the cooler thermo...car runs pretty hot

 

Mrev is a modified lower plenum. The spacer is prolly one of the best mods for the money!

 

yea i am going to go with 5/16 spacer maybe next week or so...

and is it really that easy to install? i mean i got every tool u can think of at work so i just borrow wat i need and bring em back....i actually gota see if we have a pully puller too lol

and is there any noticeable difference with the spacer?

thanks

 

i love my spacer....its one of the best things ive done so far

im going to get the MREVV2 soon as well

i believe you can do the pulley without a puller...i might be wrong though

 

yea i dont like working with the puller....when i changed my supercharger pulley on my last car it was a pain and the supercharger pulley was right on top not like the under drive pullies that are some what low

does the spacer affect the sound from the engine at all?

 

after i got my HFC's, spacer, the next thing i did was polish the manifold, and upper and lower plenum (which i modded into a "MREV"), its free if you have the tools and time. next i want pulley's

 

whats the best site to get the 5/16 spacer??

It is cake to install. Be sure to NOT OVERTIGHTEN! You could do it an an hour. I noticed a big difference.

 

i did it today, you DO NOT need a puller, you just need some patience

 

yea thats the site i had...was just checking...any specific tools ill need thats out of the ordinary? tips? pointers on install?

 

If you dont have an in/lb torque wrench be sure to divide the ft/lb setting by 12 to obtain the correct in/lb equivalent. I hand tightened the bolts first, then went to 5 ft/lbs instead of 60 in/lbs and then went to 7.5 ft/lbs instead of 90 in/lbs. I had to put my ear by the wrench cuz the click is very light. Its not alot of force. Very straight forward install, might have to tweak the strut bar, depends on how tight your car is. If you do it while the car is cold its better, once its warm its a pain.

 

excellent....thanks
