Water/methanol injection

+ 1 for Methanol , I too used Methanol @ 100% in my 300ZX TT , I made it out of ebay :) , And excepting final nozzle size (too Large) worked very well . I used a EFI Pump and under car tank , reg, boost pressure switch and LPG solenoids to ensure it positively switched off when not needed , I used Fine misting atomizers from the hydroponics industry , I ran two of them because of the Twin Turbo setup. ( one would have been Great )
Methanol is one of the best intercoolers if not the best you can have.

I have heard of others using the snow kit ,using 50/50 Methylated spirits and water , the Buick Grand National forum is a good source of Knowledge on this subject from memory .
