Thread: cant find an answer...

Ok, before any blows an O-ring, i have search the forum up and down and havent seen this asked yet.

ZZP sells two kits for adding the M90 to and L36.

ZZ-L36SSM90KIT ($200)

• Garlock supercharger gasket
• Instructions on paper and CD
• L67 brake booster vacuum line
• Idler pulley with custom standoff, bolt and washer
• Throttle body gasket
• Accessory belt (95.5" for '99+ with 3.8-4.2" pulley)
• Autolite 103 plugs
• Supercharger oil
• Supercharger bolts
• PCM reprogramming

ZZ-L36SCK ($1500+)

• Ported Gen 3 supercharger
• Machined lower intake
• Modified Fuel Rails
• 33# injectors (Stage 2 only)
• Modular pulley system
• Garlock supercharger gasket
• Instructions on paper and CD
• L67 brake booster vacuum line
• Idler pulley with custom standoff, bolt and washer
• Throttle body gasket
• Accessory belt (95.5" for '99+ with 3.8-4.2" pulley)
• Autolite 104 plugs
• Supercharger oil
• Supercharger bolts
• PCM reprogramming
• Lower intake gaskets

Now the first question is i have not seen this pop up anywhere in the forum. $200 and a second hand blower + accessories and you have boost..(?) seems to good to be true, or why isnt everyone doing it kinda thing...

Now if this is viable to do without changing the entire top end/top swap... is it really worth it for the second kit for 1500? granted it gives you the ported blower, machined lower intake, fuel rail, 33# injectors and MPS set up.

any input guys? Thanks

You either need that entire SSM90 kit which is really pricey. Namely because you need their modded rails, modded LIM, modded blower, and special pulleys.

Or the entire L67 top end of the engine/balancer/pulley brackets etc.

One of the most common questions in the 3800 market is "Can I bolt a GTP supercharger onto my GT (L36) engine. The short answer is no. The only things the non supercharged and supercharged 3800's have in common are the block and crank. Everything else is different. Still a few determined individuals have done it. This is the list of components you used to need: L67 idler pulleys, L67 idler stand off, L67 throttle body, L67 injectors, custom PCM, GTP balancer, L67 MAP sensor, L67 heads, L67 fuel rail, 2 head gaskets, head studs, MAP adaptor harness, bypass valve wiring, vacuum lines, brake booster line, supercharger gasket, throttle body gasket, lower intake gasket, lower intake Orings, supercharger belt, GTP valve covers, GTP valve cover gaskets, coil pack bracket for 99+ cars, M90 from an L67, lower intake from an L67, M90 bolts, and new rocker bolts. You'll also need a torque wrench, 3800 balancer pulley, and very powerful airgun to remove the crank bolt.

The new ZZP L36 SS M90 kit allows you to bolt a GM Gen 3 Eaton M90 supercharger to your Series 2 3800 non-supercharged engine with out the need for all the traditional components and without the extensive labor or special tools. The SS kit also allows you to run boost more efficiently on the high compression engine because of the blower port work matched with a machined intake manifold. You'll have room for easy upgrades with the SS kit as well because it uses a modular pulley system.

Included in the base package:

• Garlock supercharger gasket
• Instructions on paper and CD
• L67 brake booster vacuum line
• Idler pulley with custom standoff, bolt and washer
• Throttle body gasket
• Accessory belt (95.5" for '99+ with 3.8-4.2" pulley)
• Autolite 103 plugs
• Supercharger oil
• Supercharger bolts
• PCM reprogramming

We expect the SS L36 M90 kit to be one of the most popular items ZZPerformance has ever offered. Because of the large number of differences from kit to kit which vary by car model as well as year we DO NOT accept phone orders and WILL NOT be giving sales support over the phone. Please email all questions to customerservice@zzperformance.com or post on ClubGP.com in the L36 message forum.

To make a complete kit you will need 4 items from us as well as the basic install package found on this page.

1. Intake manifold. Your L36 intake manifold will be replaced by our modified L67 manifold found here:http://www.zzperformance.com/grand_p...ts1.php?id=235In your L36 engine the injectors fire into the intake manifold. In an L67 the injectors fire into the heads. The L36 engine in your car has different heads than a GTP which is why you need our modified intake. Add this intake to your cart choosing the drop down menu to select the SS L36 option. We recommend adding the intake gasket option unless your car is new enough to reuse the stock one. You will have to pay core charge on the intake unless you find a GTP intake and send it in first.
2. Fuel logs. The stock L36 fuel rails will no longer work. The L67 rail will not work either because it is meant to locate the injectors in the heads which can't be done on your engine. Go to our fuel log page:http://www.zzperformance.com/grand_p...ts1.php?id=259and add them to your cart. Use the drop down menu to select L36 SS rails. Upgrading injectors on 00+ vehicles requires new injector retaining clips and injector connectors. OR you can run our Multec 2 34# injectors which will work with your factory connectors.http://www.zzperformance.com/grand_p...1178&catid=113
3. Modified M90. 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. Order your blower here:http://www.zzperformance.com/grand_p...ts1.php?id=162and use the drop down menu to select the SS L36 version. You will have to pay core charge on the supercharger unless you have an M90 to send in.
4. Custom pulley. The M90 in the SS kit uses the accessory belt to drive the blower. The pulley needs a custom offset to work like this. Order your pulley system here:http://www.zzperformance.com/grand_p...ts1.php?id=205and choose an SS pulley for use with your kit. 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.

See i read both pages and the above quote on ZZP's page makes it sound like you don't need the other items. This is why i wanted to ask you guys.

So it seems to me the $200 kit is once you have acquired all parts together for a top swap and the full kit is pretty much everything you need from the "top swap' thread, just a little pricier since you are buying from ZZP as opposed to finding parts yourself... would that be a fair assessment?

ok, sounds good. this is why i wanted to bring it up. I appreciate the help guys. Cant wait to finish repairs and start working on upgrades.
