Finally got the car through the mot (cheers andy duff for advising on turning the afc down to get through spot on it worked!!! cheers) took it to the rollers to to get remaped after playing with the afc. This is where the problem started 1. When we tried to boost up the car over 12 psi the car wouldnt hold boost and was jumping up and down 1 psi but was fine up to 9-10 psi so i got the guy set it at stock boost which i believe is 7 psi it made 324 fwbhp at this settingi dont quite no how ??? and made 377 @ 12.7 psi 5500 rpm where the guy lifted off because of this psi jump . It has bigger turbos and possibly injectors (because at 12 psi the afc had loads more to go ).How did it make such high bhp at stock boost ??? Do the larger turbos make that much difference ??? Also what could be the problems associated with this psi jump ??? 2. On the last run one of the cooloant hoses gave out one of the ones at the front of the engine that go between the cam covers.Now im worried ive blown a head gasket the car didnt over heat ive heard of pipes bursting before and its resulted in a hg problems how will i know if it is a head gasket what test is there i can do ??? regards jim

jsut to add when the car was set up on the rolling road there was an egr problem (it was leaking) and the exhaust was also leaking on the flange from the turbo to the downpipe this has been fixed but was set up when it wasnt fixed so would this make a difference on the emisions now ???

i aint got the car here mate its at a garage at the mo ill come back to you on that one shortly watch this space cheers for the help regards jim

Whan doing the emisions test what is the car reved to ???

mate im a bit green all i know is it is a apexi safc i dont no what model it is . It has 5 or 6 nobs to adjust the fuel at the different rev ranges do you think this is the cause of the problem ???

What you think there could be a major problem ???

The car is at a garge at the moment they took it to get mot , its still up there where they are trying to eliminate the problem . They have had to car for 5 months sorting out an engine misfire and done some work on the egr , in this time the ticket has run out . They subsequintly took it for a ticket and it has failed , i phoned the guy today and he said the reading was 5.2 % he said it might just be where the car has just been sitting for a while or a coolant temparature sensor i dont know how that makes a difference , im just worried that its going to be something expensive like sticking valves or something ?? Also the guy said the turbos on the car were larger than stock and it runs true because i notest more than normal turbo lag since i bought the car i have only done about 1000 miles since i had the car , i had rolling roaded about 500 miles ago and it was kicking out 385 bhp at 13.5psi anyone got any i idea what these blowers on my car could be????

my zed failed its ticket on fumes could this be down to the afc set up to run 14psi see my theory is this - its set up to run 14psi but obviously when you rev the engine without load no boost is being used so at 5000rpm theres no boost but its putting in 14psi worth of juice which is big over fueling so would this cause it to fail on fumes ??? advice please if this couldnt be causing what other possibilities should i look at ??? regards jim

hey people im going to sell my zed in the near future what would people suggest the asking price should be ??? i need to sell quick because my missus is pregnant and i need some dosh quick im probably going to sell on ebay so it goes quick . Here is the spec 1993 tt import manual pearl essence white aftermarket front bumper aftermarket rear bumper side skirts de-spoilered ame 3 piece split rims 17" wider rears 2 nearly new continental sports on the rear 255 40 michellin sports on the front 235 40 uprated shocks and springs all round (very hard ride) hks super drager exhaust hks fmic with all ss hardpipes hybrid turbos hks evc 3 boost control safc fuel control all set up by sanspeed superchips running 385.8 bhp at 0.95bar with dyno sheet to validate 1 years mot What would be a resonable asking price for this chaps ??? Regards jim

D2 are fine to use mate i know them very well darren is the main guy that works on zeds he is pukka done lots of work for me on my zed infact its up there now had some serious electrical faults which he has rectefied and is sorting out a leaky egr for me i never had no probs at all with these guys very competant knowledgeable about zeds and resonably priced to

Look at it this way mate because it makes sense 300zxtt, soarer , gto ect were designed to do 150000 mile plus running around 280-300 bhp in the zx and gto case not sure what bhp soarer ie is but running a 100 bhp more on a stock engine is asking for trouble !!! 150000 miles might be reduced to 15000 or less !! depending on the condition of the engine i know what dilema you are in mate you want high power for little money unfortunately high power usually = big money the best advice i can give is take your time and find a zx that has had the money spent on it running 500bhp rebuilt engine by a reliable garage big blowers ect not to high mileage on engine and generally make sure its pukka 6500 to 7 bags of sand should get you something quite sproosy !! good luck !

just out of curriosity what would the performance of a tt zed be if its running 385bhp at the fly at an estimate ???0-60 ???? Top speed ???

cheers for the update mate maybe when you change the pump it might sort it maybe its knackered by trying to push fuel through that filter for some time keep pluging away mate you'll get there if you needed a number for a good garage let me know good luck !!!

jase i see you live in margate what garage you using to do your then mate ???
