Graham King Posted April 10, 2015 Share Posted April 10, 2015 Elie, as no one else has responded then I'll give it a go, DVA's site has a lot more detail, but Dave built me a 1800K that is 210BHP from a base 1.8K (non VVC). For that I had a VHPD head that Dave ported, added an Emerald and Jenvey TB's, the advice was that over 160BHP I would require forged pistons and modified rods so have those as well. I retained hydraulic followers and use BP285H cams.If I'd wanted to go to 220BHP then, from memory, Dave said I would need 1144 cams that require manual followers.

Ads7 Posted April 10, 2015 Share Posted April 10, 2015 It mainly revs that determine Pistons. I have a 170bhp 1800k with most work done by DVA. I have standards Pistons and rods with a Rev limit set at 7250rpm. As you are going over 200bhp I would put atleast Pistons in for a bullet proof motor.Adam Link to comment Share on other sites More sharing options...

mic Posted April 10, 2015 Share Posted April 10, 2015 Hi Elie, a change of cams, valve springs (unless they have already been done) injectors, ECU map and throttle bodies. Pistons remain as standard. Link to comment Share on other sites More sharing options...
