Passed my MOT today with only a couple of advisories... A couple of hard brake lines are starting to show signs of corrosion and my front drop links dust covers have deteriorated, which is fine as I have two brand new ones sitting on my desk! Was a bit concerned since I've just installed a prodrive sports cat but just made sure the garage gave it a blast before testing :D

Yeh i think it's reasonable... Forge are a good make

If it's adjustable you can go 50/50... or whatever adjustment you need to get rid of the lag and keep some noise!

If you experience no bad side effects to the VTA there really is no point to change it, unless you want less noise obviously :D

It will need time to bed in... give it a few hundred miles and see how it is

First error is the rear o2 sensor... expensive to get new but cheap 2nd hand... I have one in my garage that I bought but didn't need it, not sure if it works or not. 2nd error... first thing to try would be to change the spark plugs and see if the error code comes back.

R33 GTR... then go big power!

Depending on how much noise you want you have two options for the centre pipe: Non-resonated - Louder, has the potential to drone Resonated (albeit smaller than standard one) - a bit louder than standard but more civilised Dump valve - Only really if you want the noise!

Do they think it's as rare as a 22B????

Absolutely! If you're driving around normally feels no different... but when you put the foot down and tell the car to use all the boost... it pulls like a train!

HQ Garage in Dalgety Bay (Fife)... just down the road from me, mapper is a guy called Russ, he spends all his time in there mapping. Very popular as there is normally a 6 week wait for a slot... They put a message on facebook saying they had a cancellation for Friday afternoon and offered a 15% discount if someone could fill it! They charge a flat rate of £100 an hour for the dyno/mapping.

Yeh i'm happy, especially since i got 15% off so it was only £235 :D

Ah ok.. i've read wildly varying things of whp to flywheel hp... some say 15%... some say can be up to 22% loss... who knows! Either way, it is significantly faster :D

Final figure was 210whp so a little more?

Unfortunately their dyno doesn't give flywheel figures... only wheel. I estimate it to be in the 270 - 280 range since the TD04 is maxed out

Their dyno only measures wheel horsepower, so 190 is a little higher than expected due to my mods

210hp and 221ftlb at the wheels... boost is up at 1.3 bar now, only thing that was holding me back was the turbo and injectors, which was to be expected! Drives really nice, mapped in some pops and bangs for me and variable boost depending on throttle position, not had a chance to drive it properly yet but a few 2nd gear pulls and the difference is certainly noticeable!!

The remap has been done! The extra torque is pretty great!

I'll post an update tomorrow! I'm hoping to get around the 270 mark... think i've done enough mods to get there!!

Well... what I thought was going to be a 1-2 hour job turned into a 6 hour job... what a ball ache! First issue was a new nut and bolt I put on with the new downpipe was stuck after a single turn, so it had some movement but the nut would not budge. After failing with the hack saw I gave in and took the dremel to it. Once it was off i tried to see what caused it, looked like part of the thread inside the nut broke and got stuck. Anyway, started getting everything else loosened off, moved onto the last nut on the downpipe and again, got it almost off then it just became stuck!! Gave it an almighty tug (that's what she said...) and then it came free.... not the nut,... the !Removed! stud. Unfortunately I don't have a vice but i suspect it to be boogered... thankfully i had another bolt and nut that could be used in it's place. So finally got it put all together at 8PM and no leaks!! Best feeling in the world... pure relief, especially since I was under pressure as my garage had a cancellation for their dyno for tomorrow afternoon and anyone who could fill it would get 15% off, so had to jump at that! I now feel broken.... but excited for tomorrow

Sounds good! It's a relatively straight forward job! Just don't overtighten the spring bolts

Booked in for a remap tomorrow, they had a cancellation and offered 15% off if someone can fill it! Just need to replace my downpipe gasket which is proving problematic... one nut and bolt has jammed while loosening, thankfully there is a gap between the downpipe and the head of the bolt so i can get a hacksaw in there... thankfully it's a nice day!

What Savage said... :D

Remember to get new gaskets as well! Last thing you want is to fit it all and then discover it's leaking from the join... :D
