Got a 00 SSEi and am going to add some mods. I looked at intense-racing.com and they have the level 1 kit, which seems like a pretty good deal. But then again I like the looks of the thrasher CIA better. Does one work better than the other or yield more hp? Also curious about the pulleys. Which is a better pulley? Or isnt that much of an issue. Am also going to be going with the I WIN 1.90 ratio rockers and the intense PCM. Hows this sound for a starter setup? Est. hp?

First you should have a Intake (with the intense FWI, a 'RicePipe CAI or a Thrasher)
It is also recommended to install a 180* thermo
A high Flow Cat will also need to be factored in
AFTER you do the Basics.......

then you can drop the Pulled to a 3.4....the PCM would follow that....IF you plan on getting Rockers the same time or shortly after you will benefit from the higher shift points..

I would say with that setup you would be adding ~30-40 HP at the crank, but every car reacts to mods different

Well, I just bought another L67 car and my First set of mods:

105 springs
mod'd retainers
headstuds
mls head gaskets
IPCM
S1X cam
3inch exhaust from the cat on back to the "Y" (came with car)
3.25 pulley
SLP intake (came with car)

Nice set of 1st round mods I think. Depending on your budget, thats prolly the BIGGEST restraint.


But 1.8 rockers can sometimes yeild more power, and the 1.85/1.90 * do add more than just the 1.9s. If you could do a cam install I would recommend that over rockers.

The fastest L67'* run FWI over CAI'* jjust an FYI (how many other 3 letter capital words can I use? )

I recommend the FWI fender well intake too.

With :
-180 thermostat
-3.4 pulley
-Rocker 1.9
-PCM (with rocker shift point can go up to 6000rpm)
-Fender Well Intake
-High flow cat
-Colder plugs

(But you can run the 3.4 with just a Fenderwell intake and colder plugs)


Youll probably hit over 300hp easy to the crank and very low 14'* high 13'* with a good launch.

The fastest L67 use FWI just because they are all turbo'd. The fastest L67, M90'd cars use CAI'*. With saying that though I'd still recommend a FWI on a H-body just because their is not a great CAI out their for 'em.

I guess it depends on what you consider fast

I dont think that there are any 11sec L67s running anything but a FWI. Turbo or M90'ed, and turbo I/C'ed L67 really doesnt run either, most just have the filter mounted on the turbo.

Most L67 owners use their car as a daily driver, and a FWI intake is "impracticle" in everyday weather. But will yeild a couple more ponnies at times. (normally 1-2hp)

The Thrasher CAI is nice, but very expensive. I know they have one for the H-body now. You'd save a ton of money by getting a FWI or a homemade CAI.

FWI intakes are nice. I put on on my car last night, but it takes some work for it since its a tight squeeze, but you wont have to worry about say...the filter coming off or the ugly look of a rice pipe getting dirty from dust and constantly having to clean it.

Filter coming off? Have you looked at your FWI lately? LMFAO!

PIPE getting dirty? What about your filter?

I don't think a FWI is a viable alternative for an everyday driver. For a track queen or summer driver maybe.

My CAI cost me under $20 to fabricate, and constantly reads with 5° of ambient temps. And my filter isn't where it can get splashed, dusted, or otherwise maimed by road grime.
