    Hi guys got my self a s3 w reg it has had a mtm 330bhp conversion been after a s3 with a big turbo conversion for a while and more so a mtm :)

    the car has a few faults it is misfiring after 4500rpm so going to get new coil packs and plugs and see if that helps,also the car has no power going to the rear wheels.i am going to check the haldex fuse and earth strap to see if that's the problem of it only being fwd has anyone got another ideas on what else I could look at to cure the problem ??

    Yes I know but it's just the front that's spinning mate with no power going to the rear at all

    A lot of people say the Mtm is old technology , ive never owned one or been in one however my friend had an evo mr 260 running about 280bhp with Hks superdrager and we wasted an Mtm s3 I was gutted as I said " watch out there about 330bhp I've heard they are quick" my mate was well smug. Pulled over had a chat with the owner and it was a genuine!

    Anyway how do you find yours mate? How much you give for it? Got any pics?

    Cheers sean

    Yeah I do believe that the mtm kit is rather dated now as the likes of the gt28 kits and such like are a lot more upto date,I honestly don't know how it will perform as its not 100% yet but on the drive home today there was a 530 BMW harassing me and I put it in 3rd and when he went to pass I floored it and it looked like he put the brakes on lol that's the only thing I can compare it to just now and it's miss firing after 4500rpm

    I got it for a decent price mate a few things to sort out but once sorted I recon it will be worth the effort of getting all this sorted out

    Will post some pics tomorrow mate

    The top part of the wastegate is vented to atmosphere you should see a pipe from you n75 join onto a banjo or nipple on the lower part of the wastegate

    So you took the plunge in the end ;)

    Hope you enjoy and just give me a shout if you have questions about the MTM gear and will do my best to help

    nice buy

    the MTM stuff does not demand 90% from the turbo like most tuned/mapped cars, the software is only a mild tune based on the hardware as far as i am aware of

    if you want more, i bet you a custom map will see more gains !

    I plan on getting them done at some point anyway along with a front mounted intercooler but these are away at the bottom of the list just now

    i am not sure how much more power you could get, based on my knowledge of the MTM stuff on an rs4, probably another 12% both on torque and bhp, even more with an intercooler upgrade (cannot believe mtm do not sort this with the package) !!

    as already said, watch out for the rods, plenty fail on cars with 300+ bhp, there is a lot of evidence on asn to prove this !

    Have a read of my build thread mate as I'm running the MTM kit with 3" dp, 3" custom tip, large fmic, largeport head, as well as many other things, arguably I could have got more power if I had gone for a higher comp ratio as I'm running 8.5 but all in all got 335 bhp running less boost (1.5bar) ;)

    Well got the coil packs and plugs done no misfire anymore,I went for the 2.0 coilpacks with ngk bkr7 plugs with standard gap was unsure where to go for a bigger gap or not

    Since getting the misfire sorted I have been able to give it some and I am suprised with the performance as was a Astra vxr and a carrera 4 so was chuffed to bits BUT with being able to give the car some it was making a rather hard vibrating noise on deceleration and right hand bends so got the car in the air and the exhaust is rubbing against the prop in two places right at the flexi on the downpipe and right where the prop joins the rear diff has anyone else had this ?or know a fix ??
