Its off the road for the year untill the winter is over.

But Ive got OBD2 to fit to the car with C2 software so it should see me up to 400hp affraid
Also have an external bosch 044 pump and swirl tank to go on.
Few odds and ends to improve on,but its all worth it as its such a giggle to drive Twisted Evil

Cheers Shaggy,it does go and will even more once the C2 is sorted Twisted Evil

The turbo.....its doing well,kind of!
When i first fitted it i did not add a restrictor to the turbo when i should have,did not realise journal bearings needed a restrictor. Just thought ball bearing types needed a restricor.

So it started to smoke on idle with the old motor,so i welded up and drilled a .60 hole as a restrictor into the feed,it stoped smoking for sometime,then i poped my motor...silly me. Embarassed

After i built my new motor and had run it in, all was still working fine,but now on random times after you switch it off after a good run out and start it back up again after say 2-5min it will puff blue.

Apart from that it works very well and i supect me over feeding it wont have helped the seals much,but for 70 quid who cares?! Laughing

tempted to buy another cheap one with the right hotside.

£70? Bloody hell, that's cheap as fook!

How would the smaller A/R on the hot-side effect the characteristics of the motor? Would it spool earlier and quicker?

Smaller snail means faster spool time.It would spool up to 300-500rpm less,as the lag is to much for me!

Its all done besides the fuel pump which should go on later this week.
So it runs the same 9psi as it did before,it does drive the same...ish but its much smoother on light crusing and has allot more low down grunt and no more pinking! no matter what throttle and rev range.

Also the rpm has been raised 500rpm more so its now at 7500rpm,as for mapping ,dont know,i suspect the ecu is a self learing,but i really dont know.

Thats why i went down this route,plug and play fun,turn the key and forget.

i will rolling raod it at some stage,not fussed as my ass tells me how much power it has.. Twisted Evil

Well...small update,had not much time to do anywork to the car,mooving,xmas partys...and drinking large amounts of JD ! cheers

Merry times,so in the mean time i had my mate make up some brackets for my Bosch 044 pump and 16v fuel filter,decided to use a standard off the shelf filter and this does the job nicly with having threaded ends.

These are the brackets,nice job i think...they will bolt to an alloy plate were the original filter lives and then the plate will have anti vibration rubbers to stop and nastys humming via the rear boot.

Let me know what ya thinks me heartys! geek

Nice brackets!

The 044 is a noisy beast, so you might want to get some rubber damping involved Very Happy

And it pulls some big juice, so make sure you relay it off the battery.

It is a noisy pump indeed! But at least i can hear it working away..

Finished off my pump today,had it all mounted up and wired in.

Next is to sort the exhaust out,i want 3" but i like it to be a sleeper on the road,ive also seen the 3" exhaust flap which opens up on full throttle,i like the idea of this but im not going to pay the price for one so im making up my own...i will post as i go along.

Some randoms.


Rubber mounted...using kia ceed air box rubbers and also used the VR plastic rocker cover bolts redrilled and tapped out to m8x1.5mm and sleeved.

All nicley in place and the -6 hose goes through the floor to front and to the tank with ease.

Interesting. IIRC one of the Aston Martins employs the same technique to reduce exhaust noise at low load and not inhibit power when giving it some beans.

Good work on the pump arrangement. Look like a very well executed solution Smile

Well i should update this more often, sorry about that Rolling Eyes ....anyway ive had problems with the 044 pump at first,but a little head scratching and it was down to the stock intank pump being to weak to feed the 044. So i dusted off my Walbro 255 intank pump,modded the stock housing somewhat and now they both run and sound quiet!

So i went for a quick drive and realised how poor the stock 312mm tt brakes where! So my mate gave me some big EVO8 brembo calipers,after some trial fitting i decided not to use them as i would need a better wheel or to much hub spacing for my liking.

So i found a set of Wilwood six pot calipers on pistinheads off a audi/passat platform. Did a deal and bought them. Stripped calipers down as i needed to tap out the brale pipe thread from AF to metric M10X1.00 for the brake banjo,also needed to swap the link pipe and bleed nipples from top to bottom as they are directional and they were fitted to the rear of the audi hubs.

Modded the brackets that came with them and after a little while i had them fitted up with stock EBC slotted EBC discs nad EBC red stuff pads and using 2mm spacers.

I went for a quick drive and then hit a snag,the calipers caught the wheels when you braked hard as i did not take in to account "flex" as i made them sit dame close to the wheel! so another 2mm spacer... 4mm in total

Ran the brakes in,harder and harder untill they where bedded in and now they are fully bedded..... all i can say is WOW! they are so powerfull!!! the abs had a heart attack Shocked and they are smooth and progressive....love it soo much! now i have the confidence to drive into corners etc faster and harder and knowing it will stop quickly!

Just need to do the gearbox now as im hating the lazy arsed final drive! takes to long to get through the gears.... : Suspect

Some pics,modded stock intank pump housing to sit the walbro 255 with sock.
