ok sorry about this guys, i have fixed my overheating but now have a boost prob, it started when tried to road test it, it held back and sounded like a machine gun on boost, almost like overboosting. so i wound the actuator right down, same prob at 5 psi!! so then i found the multi plug to the EMFR i belive? (black box on side of metering head at the rear) hanging, so i plugged it in and it cought spluttered and died! upon further inspection i found 2 wires chopped just infront of the heater box which i was then told was ment to connect to the engine temperature coolant sensor, so i looked and it wasnt there. it was blanked off! i then got one and whacked it in ect and seemed to then idle but still missfire, i thought it was cause of co2 was out, so sorted co2 and still extreemly bad. so then i changed my cam and is MILES better, but still on full load holds back and seems to overboost but nowhere near as bad because i can now sort of build up the revs slow and drive it normal, but still will not go on full load!! any ideas are extreemly appreciated as normal guys

 

Was only revin up a bit on boost and cutting out? Cause i have the same problem!

 

well if im not driving it and i am at idle out of gear, the car revs up and dumps fine, sounds spot on.

but when driven under load as soon as the boost comes on it sounds like its overboosting (cross between a machine gun and a wet fart) and holds back, but it doesnt cut out no mate

 

Mines not revin out full on idle like iv the efi set up and it doesnt bounce seems to only rev to 6000rpm. Dam rs's!!!!!!! Im fed up with things goin wrong!

 

you and me both mate i just got 12 months mot on it and paid Ł104 for tax and cant drive it

 

Newley rebuilt engine in mine and just got it set up there and cant drive it, its a joke like! Well has and body any idea wats wrong with our cars? :-(

 

i hope so

 

Just take it to a proper RST tuner,they will have it running right in half an hour!!!Regards,Micky

 

Have you checked the plug gaps usually when it holds back it's the gaps that are to small or to big if there to big the spark gets blown out if there too small you dont get a strong enough spark.

 

and check timing too.

 

ok guys i will check this today, thanks

 

UPDATE :

i swapped amal valves over and turnt the boost right down and now it is boosting fine ect but only @ 5psi which is lame!! so i tried to turn the actuator up 1 turn and then it sky rockets well over 15 psi again and does the same?!

 

i had a scare the over day went on to full boost and just started back fireing loads. i dident no wot it was at first but every time i tried to put my foot down it just back fired. then i noticed my boost gage when i put ma foot down it was goin right up to 25-30 psi i was shit maself fort ma turbo was fucked parked up turned out a vacume pipe had come of the actuator. soon as it was put back on its been fine.

 

the actuator pipe and compressor housing pipe, should they have some sort of retaining clip to hold them on to thier respective locations?

 

i dont no i looked none off the endings to the pipes do but i have put clips on em all now just to make sure they dont come off. hope you sort yours out soon.

 

i turned my boost down and its still doing the same just hesitates revin up and now iv noticed alot of blue smoke!?

 

have u tried adjusting your mixture mate?

 

Im running Efi and cossy managment man
