Clawhammer Posted January 18, 2009 Share Posted January 18, 2009 I'm spending the winter trying to make sure I am getting the full potential out of my car for next seasons class 3 sprinting. Always thought the car struggled to pull top end revs in high gears at the fast cicuits last year. The car started life as 1.6 superlight, it was upgraded to a 1.8 by Dave Andrews by a previous owner. 4 into 1 Caterham exhaust, standard mems ECU, standard head. Original fuel pressure regulator,(Possibly squeezed by Dave) As I understand it, 1.8 K series engines run on cream injectors? Checking mine, from the front of the engine I found 1 Blue with number on the top 32332 2 green...........................32332 3 Blue.............................44332 4 Blue.............................43332 I assume there has been an injector replaced at some time and only a green one was available. Could this set up be hidering the performance of my engine? Should I fit the cream injectors? If yes where can I source these? Comments please Robin   SUPERLIGHT 176.

oilyhands Posted January 18, 2009 Share Posted January 18, 2009 It's normal when upgrading from 1600/1400 to 1800 to repalce the injectors with cream ones, the 1400s and 1600s often have blue injectors and the jump up to cream covers the difference caused by the capacity increase.. Dave Link to comment Share on other sites More sharing options...
david nelson Posted January 18, 2009 Share Posted January 18, 2009 Robin If you would like to try some cream injectors you can borrow mine.   David Link to comment Share on other sites More sharing options...
Clawhammer Posted January 18, 2009 Author Share Posted January 18, 2009 Hi David Sounds like a good idea. Are they easy to change? Robin SUPERLIGHT 176. PINK LIPS AND BITS *redface* Link to comment Share on other sites More sharing options...
mikes Posted January 19, 2009 Share Posted January 19, 2009 Robin - NOOOO - I really think you should stick with what you have got 😬 😬 If it is any consolation, mine also struggled to get to top revs in higher gears - although Kate seems to manage it OK Mike Link to comment Share on other sites More sharing options...
Mark Durrant Posted January 19, 2009 Share Posted January 19, 2009 Robin Very easy to change. Unbolt the fuel rail (IIRC there are two bolts) and remove. Remove injectors from head and replace with new - they are a push fit that seal with a rubber o-ring. Refit fuel rail. So what with your understeer problem solved with the LSD refresh and now the correct level of power from your engine I expect your odds at Ladbrooks for class 3 to shorten to odds on  Mark D Comp Sec  Link to comment Share on other sites More sharing options...
Clawhammer Posted January 19, 2009 Author Share Posted January 19, 2009 Great Expectations ehh. Depends what modifications the new bunch of reprobates in class 3 are arriving with I am still refreshing the excuses list; Catalytic converters Two season old tyres Safe bet?.......................I don't think so. Robin SUPERLIGHT 176.

Englishmaninwales Posted January 19, 2009 Share Posted January 19, 2009 Depends what modifications the new bunch of reprobates in class 3 are arriving with None.

Clawhammer Posted January 20, 2009 Author Share Posted January 20, 2009 Hi Malcolm Quote [Robin, I'm sure the previous owner of your car had a nice gas flowed head....] It teases me everytime I go in the garage and see it sitting on the bench 😬 But Should I decide to refit it I would have to enter class 4 with only 158 BHP 😳 See you at Goodwood Robin   SUPERLIGHT 176.
