look at the specs on the cat cams website. should say what you can and can't run. im running 109's in my engine. although i think you can run 110's on standard lifters________________________________________ 230 hp 2.1 16v XU 205 rallye on jenveys Project thread here309 3dr K20 Type R |

Why use BTCC cams, there made to a regulation so you can get allot better for cheaper, and they would all use Solid lifters anyway.________________________________________ 306 Rallye Sptint/Race Car, 205 CTI 1.9 8v to name a fewRoad, Track and Race/Rally car preparation to your personal requirements, Full Workshop & Diagnostic Facilities New and Second parts, from Plugs to Turbo's We now also carry out Routine Servicing www.pugracing.com & FB Page, https://www.facebook.com/PugRacing Ebay; http://stores.ebay.co.uk/Pug-Racing-Shop 2012/2013/2014/2019 Class Winners at Gurston Down Speed Hillclimb & Joint overall, Class record too along the way, |

not always best though, you will struggle to make 240 with a standard head.you can make 270+ on that bottom end with the right head, cams, solids etc ________________________________________ 230 hp 2.1 16v XU 205 rallye on jenveys Project thread here309 3dr K20 Type R |

just checked there website, requires "custom parts" where as the 109s are oem partsdon't get hung up on the "btcc" stuff, generally its overpriced when much better can be bought for cheaper. the "btcc" engine had to run inside regulations so were built to a tight spec, why would you want to build your engine to that? the inlets aren't all that either, again were devolped for regulations as a single t'b had to be retained. either way you will need an aftermarket loom, ecu and a proper mapping session ________________________________________ 230 hp 2.1 16v XU 205 rallye on jenveys Project thread here309 3dr K20 Type R |

I would suggest that the 109 catcams may be best for what you are looking for. ________________________________________ 2.1 16v 306 Rallye. |

Also different cams need different springs to suit so another point to watch, No idea on Piper spec as I avoid them at all costs, the companies had more names than I care to remember which must say something Building on a Budget can be more expensive in the long term, ________________________________________ 306 Rallye Sptint/Race Car, 205 CTI 1.9 8v to name a fewRoad, Track and Race/Rally car preparation to your personal requirements, Full Workshop & Diagnostic Facilities New and Second parts, from Plugs to Turbo's We now also carry out Routine Servicing www.pugracing.com & FB Page, https://www.facebook.com/PugRacing Ebay; http://stores.ebay.co.uk/Pug-Racing-Shop 2012/2013/2014/2019 Class Winners at Gurston Down Speed Hillclimb & Joint overall, Class record too along the way, |
