This complete kit comes with these modified pieces:
Intake manifold solution. Your L36 intake manifold will be replaced by our modified L67 manifold. In the L36 engine, the injectors fire into the intake manifold, where the L67 engine fires the injectors into the heads. The L36 engine in your car has different heads than a GTP which is why you need our modified intake.
Fuel rail solution. The stock L36 fuel rails will no longer work. The stock L67 rail will not work either because it is meant to locate the injectors in the heads which your heads do not have holes machined into them for. This kit will come with custom modified fuel rails.
Supercharger solution. The Stock M90 blower housing needs to be modified in a number of places. The fuel rails now sit so close to the blower that it must be clearanced for fitment. This work is done in the CNC mill and we run the file for our blower outlet work at the same time. As part of our outlet work we move the outlet forward so our intake will be machined to accommodate this. The modified blower is more efficient than a stock blower helping to keep KR to a minimum while running boost to a higher compression engine.
S/C pulley solution. The M90 in the SS kit uses the accessory belt to drive the blower. The pulley needs a custom offset to work like this. The stock injectors on an L36 will not support pulleys smaller than 4.2". The 4.2" pulley will give 4 to 5 pounds of boost depending on what other modifications have been performed on your vehicle. To use standard pulleys on the SS kit you would have to install a GTP balancer and all of the accessory pulleys from a GTP.
1. How long does this kit take to install?
Complete install takes 2-6 hours if doing it for your first time. You will need metric and american socket sets. SS M90 instructions
2. What cars will this work on?
Most FWD Series 2 3800 with an L36. We've tested on Grand Prix, Impala, Bonneville and Monte Carlo. Gen 5 kits will be available shortly for use with drive by wire throttle bodies and newer cars. Will not work on RWD Firebirds or Camaros.
3. Won't I have KR? Will my engine blow up?
The kit comes shipped with a very large pulley, cold spark plugs, reprogrammed PCM and a ported blower. It will make just under 5 pounds of boost. As long as you run premium gas your car will be ok.
4. What mods can I use with this kit?
Any mods that you would normally use for a Series 2 3800, except the HV insert.
5. What throttle bodies can I run?
The kit is setup to use a GT throttle body, but running a stock L67 or ZZP Stage 1 L67 throttle body would be beneficial. The PCM's MAF chart needs to match whatever throttle body you are going to run.
6. What cam should I or can I run?
Our GT line of cams will work but we recommend our VS, XP, or NIC cam for optimal performance. With L67 33# injectors and our VS cam we recommend our 3.5" SS pulley. With GTP injectors and our XP or NIC cam the 3.25" SS works well.
7. What do I have to do to run more boost?
You'll need larger injectors and PCM tuning and additional supporting mods. To run smaller than a 4.2" pulley you would need 33#, 34#, or 42# pound injectors work well. For supporting mods, we recommend the basic bolt ons like our ZZP downpipe, 180 Thermostat, ZZP or Wizair CAI, Front and Rear Power Logs-or-Headers, Cam-or-Rockers, and Short Stack Intercooler.
8. Will my car run any different?
No. It will idle the same and get the same fuel economy it did before installation of the kit.
9. What will the gains be?
On a stock L36 look for gains of 60+HP and 60+ ft/lbs of torque. If your GT is modified the gains will be larger. Because of the higher compression and longer rods the L36 will make 5% more HP and torque than an L67 with the same amount of boost. Gains at the track will typically be 1/2 to a full second from where you currently are. Traction and whether you run race gas or Torco will greatly affect times.

10. Do I need any other parts?
You will need to do an oil change BEFORE you start the car and add some coolant. If 99+ year is selected, it will come with the cast iron coil pack bracket.
11. Will I get belt slip?
No. The kit has been tested down to a 3.2" pulley with 12 pounds of boost with the accessory belt being the only drive. ZZPerformance modular pulleys grip better than anything on the market thanks to their narrowed V-groove angle. The included idler pulley increases belt wrap for better grip.
12. Will my PCM work with this kit?
No, but the kit will come with a ZZP 1.0 file setup specifically for your setup. Email Tim@ZZPerformance.com with your invoice # and any specific mods that could have an effect on the file that we will send you.
13. Can I run an intercooler with this kit?
Yes. Our Short Stack intercoolers have injector boss clearance and work with this kit. Our full size stage 2 intercooler will not work because of the injector placement. However injector spacers will be required.
14. Will my transmission hold up?
The internals of the non-HD transmission are nearly identical to the HD version. The differential is weaker but that is only stressed during launching. Any modification that increases horsepower will increase the stress on transmission components but the stock transmission is fine to around 300 crank HP. The life of your transmission will be affected more by how you drive than by the installation of this kit.
15. How much do you charge to install?
$250-$300 depending on the car.
16. What airbox & intake will work with this kit?
The same intake setup you have now will work.
17. Will my engine hold up to a supercharger?
In stock form the L36 makes 200 HP. We have tested numerous stock L36 engines to over 500 HP without failure. Yes, it will hold up.
18. Do I need a pulley puller tool?
No. The blower will come with the modular hub pressed on the snout. Pulley changed will only require an allen tool.
19. Has anyone installed this kit yet?
Yes, we have installed a few on test cars and shipped many kits. Daniel Schmidt is a customer currently running 12's with it and very familiar with it's installation. He can be emailed at: Courtesy_automotive_service@msn.com (has lower case lines in-between each word)
The last customer to dyno (Josh in MI) made over 250WHP with a 4.0" pulley!

275WHP http://videos.streetfire.net/video/2001-grand-prix-GT-DYNP_208097.htm Mods are ZZP m90 KIT. headers. 1.9 rockers, 3.6 pulley
Nick Perri ran 13.1@103 on 93 octane with a 3.4" pulley. His full build can be found in our member's car section.
20. Do I have to upgrade my fuel system?
The stock OEM fuel pump is good down to a 3.5" pulley. To run a 3.25" you'll need the Alternator voltage booster and fuel pump rewire. However if you have a Autozone/Napa/Advance etc, china pump it will be maxed on the Stage 1 kit.
