Modifications

[AWD Primera]

Im keen to know what modifications people out there have made to their engines and what the resulting power/torque increases were? Im interested in going a little bit faster.

check www.se-r.net.

They have a lot of info on engine modifications there.

I have these engine mods so far:

Hotshot Cold Air Intake
Hotshot 3rd Gen header
UR pullies (2 set)
Advanced timing to 19*
Lightened Stock Flywheel (about 13lbs)
ACT Clutch
recent tune up too (plugs, cap, and rotor)

I put down 141.1hp and 133.4 ft.lbs at the wheels a couple weeks back. These numbers are a tad higher than I've seen for others with the same mods, but i'm sure there are others with similar, or less mods making more power too. I think this equates to about 163hp and 154ft.lbs at the wheels ??? Hope this helps

My last dyno run had:
JWT POP charger
Unorthodox racing pullies (2 set)
Custom exhaust
19 degree timing

I ran 135hp and 128 torque. Pretty high for my mods. Since then I've added the JWT S3 cams and a Hotshot header is going in soon. Then I'll hop on the dyno again...hopign for close to 150hp.

excuse me G.can you tell me what was the price you paid on the unorthodox pulley set and the hotshot headers? on the pulley set ,what were they for.which did they replace?thanks dude

i'm curius about the pulleys also, 2 or 4 pulley set, which is better? and would they work on a 2001 g20? i know the 2 pulley set replaces the water pump pulley and the underdrive pulley and the 4 pulley set includes the alternator and the a/c, correct me if i'm wrong :smoker:

oops, i'm wrong lol the 4 pulley set comes with the underdrive, water pump, alternator, and the powering steering pulleys but no a/c pulley

I think you mean the crank pulley instead of the underdrive pulley, but yes, I believe that setup is correct. Between what I've heard, and what i've seen on cars, there really isn't that big of a difference between the two sets. The 4 pulley set is supposed to make a hp or two more. I've also heard the the throttle response feels a lot better with the 4 pulley set rather than the 2 pulley set. But, I may just be spewing BS here too, this is just from what I've heard or read in the archives or on the se-r list.
Oh yeah, as far as price difference, I got a quote for another LM at a local shop here in Phoenix. 189 for the 2 set (however I paid less at the same shop), and 249 for the 4 pulley set. Hope this helps.

I buy most of my parts on group deals...I think I paid ~$140 for the 2 pully set. Don't get upset if you can't find that price, it was too good a deal to pass up at the time. The header was $425 from JWT.

The difference between the 2 and 4 pully set is minimal hp gain and maximum frustration for installation. Basically if you just want to 'finish' off the look then get the 4. IMO the extra cost and installation difficulty is not worth it.
