    thanks ben, i think its a fantastic acheivement to do 310-320rwhp with minimal mods, it realy showcases how great these engines are. mine did 310 when i first got it with those mods and it performed really well on the street.

    So the plan is to hopefully get the motor out this weekend and kick things off. might have it running within a few weeks or a bit over a month

    I like your style Niall. You are doing basically the same as me.

    Except I couldn't resist going with an oiled pod filter. I also want drivability and a really well tuned/maintained car to enjoy driving daily and driving through the occasional twisty.

    When I have the money I will look at increasing off-boost responsiveness by reducing rotating mass - lightened driveshaft, flywheel (maybe not now I just read the other thread on this), wheels (probably not the wheels:D) etc and possibly strip some weight - recaro seats, remove hicas, AIVs etc.

    I never really found myself looking for more bottom end, it was the top end i was looking for.

    Although my car was rooted when i took it off the street, i was still a good comparison.

    Maby i was just looking for the missing top end that i used to have.
    Interesting to see how it will drive when its finished.

    Actually what the difference between the blue zed and this one, apart from the power.

    Is there much difference between smoothness, idle, noise ect. Between a old engine and a rebuilt one.?

    having driven a zed with a lightened flywheel and udp the difference in response and revability is really improved.

    increasing your ignition advance can really help off boost response too. has it been chipped yet?

    I don't think the ecu has been chipped. Will this make

    an appreciable difference down low? My det sensor is bypassed at the moment so I want to be conservative. My last TT, which was an auto, had the k-zed chipped ecu, but I did an exhaust upgrade at the same time as installing the ecu so I couldn't tell where my improvements came from.

    I'm a bit concerned about driveability with fitting a lightened flywheel after reading the thread on that issue tonight:confused:

    hmm, ive never experienced any negative effects from a lightnened flyhweel, but maybe it differs from brand to brand.

    increasing the timing will certainly sharpen it up off boost. detonation off boost is not something we really have to worry about unless you try to pull out of a corner in 4th.

    could sell you a copy of the chip i do for this car when the time comes if your interested

    Benny_C About as subtle as...

    Jet Power, That particular chip in your ECU that you mentioned won't make any responce difference. it will just remove the speed limiter and increase the rev limiter. As for the exhaust upgrade, well, if it was from stock then that should be the thing that increases HP if it was from a stock exhaust, as the stock exhaust actually has restrictors in the pipes just after the cats.

    Lightened flywheels will make the engine rev quicker but also make it decrease reves quicker and sometimes a prick to take off on a hill if it's too light. And i'm speaking from experience from my other Zed that had a light flywheel. Give me a stockie any day! :)

    The Det sensor bypass will retain full stock boost at 9psi however, and if you were getting Det Sensor errors previously then it would have been restricting boost to 7psi and an over-rich safety loop AFR which will over richen your fuel and decrease power aswell. So a few issues there that may have all contributed to extra power when all applied.

    Thanks for clarifying the ecu function Benny. I recall

    Rob saying that it also changed the fuel maps to lean it out in certain conditions, as well as allowing the use of 95ron. Even so, I've always used 98ron anyway.

    Niall I could be interested in copying your ecu mod if the cost is reasonable. I look forward to see how that and the other mods go on your 'legal eagle' :D.

    yeah wait and see what the results are, no point if it doesnt perform :)

    Good project mate, hows the factoryairboxes in these as in inlet restrictions? Only ask as a 2nd hole mod + a good K&n can be just as good if not better than pod setup.

    BTW if you ever feel 2 zeds are too much I'll take it off your hands lol

    lol ill keep that offer in mind. haha.

    Personally i dont think the stock airbox is a restriction, mine didnt show any real gains when i switched to a massive HKS pod.

    time will tell with this car tho

    heres the tyre plackard , should be able to run the 8.5;s and 9.5's legally

    Baselining it on the dyno day in a couple weeks man? :D

    dont think that will happen lol. maybe the summer dyno day. :D

    between working on michaels car, marcs and doing a manifold gasket on a vectra i test fitted one of the wheels, couldnt resist.

    Looks like 1 - 1.5 degrees negative camber will keep

    you out trouble and fill out the guard nicely. A bit like mine, although I must have about 2 -2.5 degrees at the moment.

    Just looked at my sig and probably closer to 15 degrees camber :p

    they are 9.5's but ill probably run a 245, that should sit in a bit too.

    Thought you wanted it legal? :p
  19. rollin

    that would still be ok tho right?

    im running 245 on my 9.5 18's and it looks kosher

    HEY! Fitting wheels don't fix my car, get back to it chop chop! Nah kidding, be interesting to see the results of this. I don't think anyone has tried to do this before.
