ok basically i melted a piston 6 months ago,my mate has just rebuilt the engine and dropped it back in,car starts up,but it seems to hesitate/miss and hold back when the turbo kicks in,which is exactly what happened before it went bang,so the problem is still there,

so do i have to first run the engine in and then take it to msd to get it set up and looked at or take it straight there to get it sorted? or does it need to be run in 1st? i dont want it to go fooked again so can someone point me in the right direction,STU?any ideas what the problem is?

any advice much appreciated

 

anyone? i'm thinking of going straight there but could it be sorted before its run in??

 

if you are running less boost mate to run it in.
it sounds like the timing is prolly out?

 

Bill,
If shes runnimng rough now, its going to affect the run in and cause more damage than good, so you have really to do two things regardless of where you want to go.

1) It needs to be diagnosed/rectified/setup safe.
2) It needs to be run in following your engine builders brief.

Its then up to you where you go and what you do from there on in, but an engine should never ever run badly no matter how young or old it is.

Hope this helps.

 

stu,i'm local,if i brought the car to you as it is could you sort it out for us? just waiting to get it through the mot 1st though

 

oh yeah,my mate rebuilt it in his spare time,he used to be a mechanic,saved me a fortune,so no real instructions as how to run it in

 

I can sort it no problem, but be aware that if its on an "Off the shelf" greys chip it may NEVER run right and you may need to sort the software side of things first.

 

no problem,so i take it i'm best bringing it straight upto yours,without attempting to run it in then?

if so i'll get it mot'd and book it in with you straight away,

thanks again for your advice,much appreciated,i'll be in touch
