and the story begins....
Bought an Evo IC from Bo a while ago, problems with the delivery (parcel force heavy handedness) damage the bracket on the IC (IC to Crossmember bracket) so sat around waiting for parcel force to sort it out, eventually sorted
Really excited after sitting and looking at the IC sat in the living room for 4+ weeks, thought id fit it, problems fitting it, the stainless steel bracket that is used to fit the RS2 Evo IC to the ABY s2 crossmember is useless bolted it all up and the pulley and IC were in constant contact (all new genuine engine and GB mounts fitted 1000 miles ago) so after faffing around for hours spacing the IC from the crossmember and strugling to then fit the bumper took it for a spin
Boost leak (well assumed it was/is)
right, all off again
checked all the hose connections (including the Mark H mod) all seemed ok
gave it a bit of a giggle with the clips slackened off
went for another drive (bumper off this time)
1 and 2nd gear seemed ok, 3,4,5 and 6 accelerating while keeping an eye on the boost guage (MTM remap 1.4 bar, tails off a bit at redline) 3rd gear floored it, boost shot up to 1.6/7 bar and immidiately tailed off to about .8 same in 4/5th gears
wouldnt hold boost
back to the drawing board, did this a few more times, same results, no change, bumper back on, leave for another day......
monday, bumper off again, same procedure as befor, same result
yesterday, bumper off again!
everything off again, changed the Mark H mod pipe and clips for another i had, replaced all the boost pipe clips with new stainless steel ones from the local samco dealer, took it out 1, 2nd again seemed ok, 3,4,5th and 6th ewww horrible!
hessitation under load, low revs wouldnt go above about 75/80mph limped to my parents, checked everything, changed the mark H mod again for the other spare (3 in total tried now!) no change, drove it home last night, same horrible hessitation, struggling to hold motorway speed
drove the car today, befor i set off, had a weird squeeling on idle from the car, so lifted the bonnet, nothing there, revved it a few times, dont know why, but unplugged the N75 valve, then plugged it back in set off, 1st, 2nd felt ok, but only boosting to about 1bar and dropping off rapidly, 3,4,5 and 6th all felt better, no hessitation, but only boosting to around 1bar 3k rpm and dropping off to about .8 by 4k rpm
stopped the car in gravesend, changed the N75 valve with the one off the other avant (unknow condition) disconnected the battery for about 10 mins to clear the ECU and drove to the petrol station, turned out the N75 valve i fitted off the other car was FUBAR only had mechanical boost .4bar stopped at the petrol station, swapped the N75 back, boost restored (well to 1bar-0.8bar
)
got onto the A2/M25 to drive home, and the hessitation had come back in 3,4,5 and 6th, not as bad as before but still noticable, could do 80/90/100 pushing through the hessitation, about 10 miles later on the a21 put my foot down and the hessitations gone again, still only the 1bar tailing off to 0.8bar
the other weird thing that started happening last night was the temp guage (water) works intermitantly
any suggestions?
all was fine befor i fitted the new IC
