Guest Terry S Posted July 16, 2002 Share Posted July 16, 2002 Hi guys, well the car went on the dyno, but struggled due to an ignition problem. It is fine up to 21 psi then get's a miss. It's not the amplifier as I have a new CDi ignition system so it all points to the coils. The plugs are BKR7's and where gapped as low as 20 thou to try & rectify this. I have ordered new coils from Jay Marks in the US for HALF the cost that Jemca wanted! I'll let you know if this is the cure. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 16, 2002 Share Posted July 16, 2002 Terry How much were the coil packs? cheers Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 16, 2002 Share Posted July 16, 2002 Depending on the exchange rate about £300 shipped. Jemca wanted £579 (for all) & only had 1 in stock! Quote Link to comment Share on other sites More sharing options...
mark brown Posted July 16, 2002 Share Posted July 16, 2002 Terry Are you sure it is the coils? If you are running standard ECU and 440cc injectors you may well find the engine is running extremely lean at 21psi. Running on standard 440CC even with my Blitz Race ECU which has a richer map, still showed leaning out at this level of boost Experiments undertaken by others and myself on this board have confirmed that above 1.2 bar on standard Jap spec, mixture leans out. I had to fit 550Cc injectors to run my Turbo Dynamics hybrids at this pressure safely and without misfire. I also run an additional injector kit to allow me to take the boost from 23psi to 29 psi.

Terminator Posted July 16, 2002 Share Posted July 16, 2002 I have been in another car with faulty coil packs, the miss was only at high rpm and boost. Terry do you want to try out my spare set to confirm the diagnosis, before shelling out £300 or is it too late? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 18, 2002 Share Posted July 18, 2002 Thanks Phil for your kind offer, but I have already ordered them. Mark, the mods go way past that;) Quote Link to comment Share on other sites More sharing options...
mark brown Posted July 18, 2002 Share Posted July 18, 2002 Terry What mods have you done then? I've fitted 125bhp nitrous kit. I understand that you are doing this. Whilst it improved spool up, it was not as effective as I had hoped, could be that I went over the top on the spec of the hybrids, cos there is still a fair bit of lag. My mods listed below Mark MIKV j Spec TT auto Blitz DSBC, Blitz FMIC, HKS AIC Kit (2 Bosch grey injectors), UK spec 550cc injectors, Blitz Dump Valve, HKS 254 Inlet & exhaust cams, Blitz NUR spec exhaust (no cats), 125 BHP nitrous kit, water injection, Turbo Dynamics Hybrid Turbos (running Max 2 bar), Inlet charge temperature measurement system, EGT & Boost gauges, Blitz filter mounted in wing (cold air), additional oil cooler, AP 6 pot front brakes, Eibach springs Quote Link to comment Share on other sites More sharing options...
