Notes:
· This kit is sold for DIY kit installation - Please note the pre-installation requirements above.
· For increased power, use a HRC
or stage 2 hot cam and heavy duty valve springs, these are available at extra cost.
· For even better results, we recommend the use of a good after market exhaust system.
MW Racing Recommendations:
· Vertex programmable ignition allows you set up power delivery to suit your needs (SM Magazine preferred a map which actually tamed
the power!)
· The FMF power bomb header and Power Core 4 silencer fitted as a complete system came out best in our own dyno tests and is not too expensive.
We have also noticed that this system is much better quality than it used to be!
· For cylinder head porting and carburettor boring, SCT Race Engines consistently produce top results.
