The cams are "roller' designs and costly (cam only, around 250.00  us)
That L35 ballance shaft engine has improved cylinder heads
over previous years.  Something like 17% on the intake side
 & 12% on the exhaust.  Syclone & Typhoon owners are selling
their first born for the cylinder heads.  A good set of headers, in 
addition to your throttle body install, will make for most fun per $$
invested.
Not sure if you need to tweak the base inj.pulse or not.  I assume
it's a PITA OBD system?
