'R PH3 Cams
Hi all,
After FCS it's likely I will cam my 'R with some Newman PH3 cam's. Before anyone say's just get an 'S I can't due to insurance and I would rather cam my 'R and buy a much better car in the future ... I have a few questions I was hoping you lovely Sax-P people could answer for me :) I take it there shouldn't be any problems with MOT such as emissions? Also it says these retain a smooth idle but am I right in thinking it would be better to unlock my ECU and get it mapped? For the idle and getting the max power out of them? Lastly I have been told you should uprate the valve springs? I know people have run them on OEM before but for a few £ more is it worth it? I have the silvertop 'R engine. Cheers, Matthew. |
:bump:
Anyone? |

hi Matthew, come MOT time emissions shouldnt be a problem with the PH3 camshaft provided a CAT is present, im pretty sure the PH3 is near the limit for a standard bottom end due to piston/valve clearences. personaly i would buy new valve springs when fitting the camshaft dont cut corners, but it depends on budget and how much time you can have the car off the road, if you havent got a valve spring remover, you can get them removed/re-fitted when getting the head skimmed to make sure you get a perfect mate when re-fitting. |

How likely is the bottom end to fail and what would be done if I had the bottom end uprated for the cam? Valve springs are a defo if I purchase a PH3 cam, might aswell do it properly. Do you know if I would need a remap on the ECU? Cheers, Matthew. |

The bottom end won't fail, he just means that silvertop camshafts that are available wilder than PH3 spec likely need pocketed pistons.
Get some uprated valve springs from Piper (~£60) and a vernier pulley. Fit the cam to standard timing then have the timing tweaked on the rolling road. No need for a remap with the PH3 imo, although others may tell you different. I ran a similar spec Kent cam with standard valve springs on the standard map - car made 118bhp at the fly after having the timing tweaked. |

For the effort and money it cost, I'd say it wasn't worth it at all. To make the most of the shifted power, you ideally want something like a VTS/ S2 Rallye/ 1.4 XSi gearbox too. In short: 16V conversion is what you want. :y: |

Thanks though, I was already planning an XSi box anyway. I would go for an S1 but its probably too short for a VTR on standard rev limit, plus i'm sure it would drink fuel lol. |
I thought the same when I first stepped into a standard VTS from a cammed VTR. Once you adjust and change your driving style, you'll never want to go back to a VTR. Unfortunately, you do get royally shafted on tax with 2001+ VTS'. :(

Hey, dint want 2 start a new thread to ask the same questions but i have found these on cam racing http://www.kamracing.co.uk/index.php...camshafts.html does this kit include everything i need 2 cam my 2000 reg 1.4 furio???
|
2000 reg will be a silver top engine with roller rockers IIRC. The cam you've linked is for a black top with non-roller rockers.
If your engine is a silver top, you want the PH3 for roller rockers. :) |
O.k i see lol, cheers.. http://www.kamracing.co.uk/index.php...camshafts.html these are what am wantin then, will this kit include pulleys, valve springs ???

O.k, sorry if im hassling but how much you think ill be looking for a full setup then ?? camshaft, valve springs and pulleys???? does'nt matter if you dont know
|
Camshaft ~ £200.
Valve springs ~£60. Vernier pulley ~£100. Head gasket and head bolts ~£100. Also need oil, coolant etc. Then labour and dyno time to adjust the timing. Expensive for very little gain imo. |
just save the money...
its the better option in every way |
Woow was'nt expecting that much :o you dont really see much gain either lol
