First of all, do you want 300-320 crank or wheel horsepower?

I am assuming since you don't want to change your cam then the answer is crank horsepower. Our level 3 package will get you there with no problem.

Headers
Hi flow cat (or race pipe)
1.9 rockers
LS6 springs
OR Rods
3.2 pulley
standard PCM
FWI
180 T-stat
cooler plugs

If your looking at doing this in stages then the following:

Step 1
FWI
3.4 pulley
104 plugs
180 t-stat

Step 2
1.9 rockers
springs
or rods

Step 3
Headers
Hi flo cat (or race pipe)
3.2 pulley

Thanks for the input, This is exactly what I needed. But I will be looking later to going to more HP. I'm just looking at HP + Torque. Not so much interested in 1/4 mile times yet, this is my daily driver, I just want to hit the throttle and go really fast. I will be going with an G3 LSD, In the near future. But I like to upgrade my all of my Non-HP generating items 1st so I have the proper Hi end Maint. items.

Great:
This is awsome. I have the Plugs and 180 T-stat (not installed yet). So I still need the 3.4 pulley and the FWI, would you also recommend the PCM in the 1st step? I'll be going to your site tonight to take a look.

Yes PCM should be a priority. Keep in mind though if you want to add more in the future it may make sense to alter your modding early on. For example you may not want to do rockers if your doing a cam since you have to use 1.6 rockers with a cam (negating the 1.9s). A good compromise would be to do 1.9s with 105# springs instead of LS6 springs. This will allow you to only change rockers in the future when you do the cam instead of also having to change springs.

Great points and I will take these into account. Thanks

also, if you really want horsepower, dont waste money to the 3.4, wait till you get enought to do the 3.2 and supporting mods,

the 3.4 will give a nice bump from stock but not coming close to your goal, imo.

i got from 15.2 to 14.9(with wheel spin) with only a 3.4 and a FWI.


..in the same way, how much cost the 1.9 rocker with install (im in Montreal, canada )

anybody know where i can get them install? (Foghorn?)

wow that good info you guy gave him but does any of it apply to me?. can you help me in the same way you helped him with my 1992 SSEi??

I am not undestanding exactly if you are wanting 300-320 crank or wheel horsepower but anyways if its wheel horsepower then wanting to do it without changing your cam isn't really too practical. IIRC there are only 2 or 3 M90'd stock cam L67s that have made more than 300whp and none of them did too much over. 315 is the record and while thats respectable it takes just about every other thing you can do to the engine to make that kind of power with the stock supercharger and heads. 270-280whp isn't too hard to accomplish without changing the cams, but hitting over 300 is pretty difficult. My recommendation for you would be to go with a semi-mild cam like a ZZP XP cam or an INTENSE Stage 2, an intercooler, and then your regular mods like headers, pcm, intake, high flow cat, modular pulley system, etc... That would easily put you in the 300whp range without too much spending.

But you can do this all slowly also, you don't have to do it all at once, start out with the little stuff and work your way up to bigger things. I would not put a press on pulley on the car either, if you are going to invest in a pulley get a modular pulley system so its easy to change the pulley size later after you do more mods.

Thats what I would do in your position...
Hope that helps.

There are far few mods available for the Series I 67, the Series II was found in far more cars adding to the demand for aftermarket supplies.

Series one mods are out there...but most are "personal" designs etc. See Bill Wrens 93 SSEi as an example. Packaged Series I performance simply doesnt exist in comparision to S2
