Its a 2.5 single turbo, 1993, its got fully forged engine block, hks mushroom induction kit, hks dump valve, 555cc injectors, uprated ecu and thats all im aware of. I'v just bought the car so am still learning but i'v got a budget of £2000 to spend on the car, its due a full major service - timing belt kit as well. I'd like to purchase a fmic as a mod and any money left over from repairing it want to spend on mods. Also when you red line the rev meter the car spits flames from the exhaust even though it has NOT got a flame kit. I don't know if thats an issue but i don't mind lol. With the money I have what kind of mods u guys think are best? And is the problem defo the coilpacks? Anyone had the same problem?Whats the full spec? we cant diagnose whats wrong when we don't have all the info. there could be so many causes.
Coil packs are not part of a major service, sounds like you have a a vent to air BOV which will usually cause the engine to flame on lift off/dump when on boost, however the fact that its doing it at WOT indicates that its missing at high load, so it could be down to coil packs or over fueling, but it still could be down to the limiter still being in place, is there a definite misfire that you can feel?Im not sure i'll have a look and get back to you on the ecu. It spits flames when foots fully on the throttle and u red line it. And im not sure if the bov is vent to air. It just days hks on it. Im thinkong because i'v got £2k to play with i'll change the coilpacks anyway because they should be done at a major service right? The cars done 115k km and I don't think its been serviced for a while it was in dry storage for 2 years
