I'm in the process of supercharging my 2002 at 108k miles. I'm trying to write a comprehensive list of everything needed before I continue. What's listed is what I know I need/have ready.

-ACT HD Pressure plate and disc
-OEM flywheel (resurfaced)
-Grams 1000cc fuel injectors
-AEM V2 ECU
-Kraftwerks v2 + upgrades
-HONDA high temp lube
-2 qts Honda trans fluid
-OEM replacement pilot bearing
-OEM eplacement throw out bearing
-Rear main seal
-Prop shaft bolt replacements

-boost gauge with recall
-wideband afr gauge
-spark plugs, NGK #2668 gapped .025-.028

I'm going to need to either replace or spot weld a small crack on the prop shaft that we knicked with vicegrips. I've budgeted for an alignment, tune, dyno, compression and leakdown test once installed.
I have stock headers, Invidia test pipe and an HKS Hi Power single exhaust.

My question is, what other hidden expenses do I need to know about? Spark plugs? Clutch fluid? Etc. And thanks in advance! I'm really excited for a reliable 425 whp.

 

Couple things off the top of my head after reviewing your list.

1.Use the oem friction disc with the act PP, smooth quieter engagement with same /plenty of holding capacity for your set up.
2.You will want a wideband afr gauge and boost gauge with a boost recall feature is best, both of these will come in handy for troubleshooting tune issue and belt slip etc initially and down the road. Flying blind otherwise.
3. Do the compression and leak down test now before you invest in FI set up to make sure your engine is worth investing in.
4. spark plugs should be replaced with one step colder then stock. The most common swap is to the NGK stock # 2668. These come gapped about .033 out of the box, but will need to close that gap to about 025-028 typically for high boost/15+psi.
5. I question Grams quality in fuel pumps and injectors, if these come with the Kraftworks kit then it is what it is, but you may want to look into more reputable options such as Injector Dynamics 1000cc injectors and Full blown 340 fuel pump.

 

This is exactly what I'm looking for! thank you..
I've heard that I'll need multiple sets of spark plugs. For the tune, and then replace after the tune, and then replace again after a 500-1000 mile break in. This seems excessive to me..

 

That would be excessive. In my experience, I don't see it being necessary at all.

 

Can I reuse my flywheel bolts with some locktight or replace with ARP?

 

I'm not sure what climate/environment you are in, or if you plan on tracking/racing your car, but something else to consider would be a better radiator (Mrsideways/Dual Pass highly recommended) and an oil cooler. The intercooler will block a significant amount of the air that reaches your radiator, and it will not perform as efficiently as it could, that's also not taking into account the increased heat and complexity that the supercharger will bring. It may not be an immediate need, especially as we are heading into the winter months, but probably something you should keep in mind.

 

everyone has set you on the right path. I make as of today 455whp 305tq @8500rpm with 18.5psi boost on a novi 1200 running through my own custom built air to air and cold air intake. I am running what amounts to a 3.2'' blower pulley with many supporting mods too much to mention here. if you plan to tune the aem v2 yourself look up Jonathan fasking youtube videos on tuning it will change your boosted life. It has mine check out my fuel pump install in my signature if you have questions after you look through my build page let me know
