Injectors I can get for you let me know what you need. Price $65.00 ea. 28.8 # 35.5 # 44.5 # If you are using the stock manifold these are non shrouded injectors so a injector adapter sleve would be required for install. -Chad | | | 10-29-2004, 06:19 PM | #3 | Senior Member Join Date: Aug 2004 Location: Tyler, TX Posts: 1,022 | Pistons usually run from $400 - $500 for a set of 4 with rings. I would try talking to Arias, JE, or Paeco and see if any of them have the specs on hand so that you don't have to send in a piston or make a mold of your combustion chamber. Good luck with this and let us know how it works out. | | | 11-03-2004, 06:43 AM | #4 | Junior Member Join Date: Nov 2004 Location: lafayette, la Posts: 26 | hello i have a 97 with a mosselman turbo (g25)i was wondering if anybody has a air\fuel ratio gauge hooked up and what the reading is and how to fool the computer | | | 11-03-2004, 11:00 AM | #5 | Member Join Date: Oct 2004 Posts: 31 | "hello i have a 97 with a mosselman turbo (g25)i was wondering if anybody has a air\fuel ratio gauge hooked up and what the reading is and how to fool the computer" I would suggest that you buy a wideband 02 sensor and guage because thats the easiest way to tune your engine precisely. It will cost around $300-400, but will be well worth it. You can also buy a fuel comtroller that adds or takes out fuel at various RPM points by cutting the voltage of the AFM signal. Someone else needs to chime in about how the 318 CPU works to measure air flow. | | | 11-15-2004, 05:01 AM | #6 | I miss my Ti....... :( Join Date: Nov 2003 Location: Los Angeles, CA Posts: 828 | Fuel Probelms..

It cost me like $200.00 including the sender and is not worth the space that it takes up. But if you are into looks its for you. As to measure Air/Fuel use a Lambda Meter or the AEM Wide Bahn Kit. As for controling fuel you only can do so much with AFPR. The next thing would be bigger injectors and a piggy back kit to run them. I use the Split Second MAF Kit with the ARC II, and it has been working well. -Chad | | | 11-03-2004, 11:18 AM | #7 | Junior Member Join Date: Oct 2004 Location: Bradford, England Posts: 3 | Thanks Guys I Have Been Quoted $650 For A Set Of Pistons With Rings From A Place Called Top-end Performance Near Hollywood, Plus $79 Shipping, Is This Expensive? Does Anyone Have The Websites For The Other Piston Manufacturers At Hand? Chad: Im Looking At Fabricating A New Inlet Manifold So Il Let You Know Bout The Injectors, Thanks Man Cheers All | | | 11-03-2004, 02:24 PM | #8 | Member Join Date: Oct 2004 Location: New Hampshire Posts: 68 | Try contacting some of these piston manufacturers. Not sure if any have M42/M44 pistons in stock, but I'm sure they'll custom make anything you have in mind. These guys are all top-notch forged piston makers, commonly used in the BMW forced-induction world. CP Pistons Ross Pistons FYI, Ross lists custom 4-cyl pistons for BMW's at less than $500/set. Wiseco Pistons I believe Top End does not actually make their own, but rather has JE Pistons make them: JE Pistons Those Ross pistons are a bargain compared to the TopEnd/JE ones, and probably better quality.

At 10PSI with stock ECU and stock injectors you can kiss your engine good bye. SL PS Mosselman's turbo kit uses T-25 turbo.
