4AGE_BOI Posted January 2, 2008 Report Posted January 2, 2008 Hey Guys.. So i ave just finished a 4 month silvertop engine conversion.... i am having some issues. The engine has been completely re built... And it is in an AE82 Rolla CSX the twin cam 16 V came out of it. The 20V ECU is in it, as well as the 20V injectors. Now the Silvertop 20V is rated at (121 kW) at 7800 rpm mine will not rev past 7000 it seems like there is not enough fuel. Do i need to replace the 16 V Fuel Pump? Also the torque is supposed to have 162 N·m at 5200 rpm, The most of my torque seems to come in at 3900 RPM. It is really bothering me. Any thoughts at all........... Quote
4AGE_BOI Posted January 2, 2008 Author Report Posted January 2, 2008 100 octane sometimes more. Quote
Medicine_Man Posted January 2, 2008 Report Posted January 2, 2008 Fuel pump could be f@$ked/not able to deliver enough pressure, able to put a pressure gauge on it? Also may be something to do with the speed sensor, Do you have the speed sensor from the dash connected to the ECU? Quote
4AGE_BOI Posted January 2, 2008 Author Report Posted January 2, 2008 My initial thought was the fuel pump..... I'm replacing it anyway...... I have a walbro 550hp with a 2 ltr surge tank.... I'm going to install that just thought maybe there would be something else.... The fuel lines (on idle) are solid as, although i can't feel them at 7000 rpm, Quote
love ke70 Posted January 3, 2008 Report Posted January 3, 2008 do you have a speed sensor connected to the ecu? if it doesnt have any speed sensor connected it will think its free revving and retard itself. Quote
