got the fabrication of the exhaust/turbo pipework finished today only the charge pipework ,oil lines and scavenge pump mounting in the engine bay to do the tailpipes need cleaning up and polishing this is what it looks like off the car this is the view from underneath might get started on the charge pipework Friday as I'm off unless the missus has plans

I have Sewage worker latex super tough not the place to have glove failure

Chris I'm going to buy you some decent gloves for Christmas you know you're supposed to keep your hands in them right ?

Good work as always Chris even if you didn't plan on it

Dedication or pig headed

Exactly why I'm going with it the rarity factor

well my comment in the above post about my new tailpipes arriving damaged was a major understatement mangled to F*&% would have been closer so they went back and i decided to make my own I think they would have been a bit small anyway so this is what i came up with, what do you think I think I will have modify the rear valance to make it look right but I think the four 2 1/2" pipes looks pretty cool the inside 2 are 3mm longer so it follows the line of the valance better This is the valve which will shut off the straight through section of the silencer to quieten down the exhaust to save annoying my neighbors I won't get any more done now until Sunday the new aluminium charge pipework arrived today (The previous version used thin wall stainless) other than some silicone hose I just need some time.

exactly throttle body spacer the spiral grooves are supposed to improve air fuel mixing can't quite believe that the gasket looks like a phenolic or other insulating intake gasket it goes underneath the plenum to insulate it from the engine to reduce plenum temperature which theoretically reduces intake temperatures as for bolts you will need longer bolts for the plenum and the throttle body i think they are all M6 but dont hold me to that get them where you can ideally avoid stainless unless passivated most stainless bolts used in the motor industry seem to be yellow passivated which basically stops them reacting to dissimilar metals i always put mine in with a bit of grease or copper grease.

Not much of an update just trying to update as I go Had another change of plan as the Backbox I was going to use was pretty much destroyed by the courier company looked like they played football with it the delivery guy kept apoligising it was so bad so rejected delivery and cancelled order and decided to reuse the old one instead got most of the welding done on it today (no pictures sorry) just got to cut off the old and weld on the new tailpipes and weld on the valve that feeds one of the tailpipes so i can reduce the noise level to save irritating my neighbors just waiting for my new tailpipes (which will probably arrive damaged) and need to refill my gas bottle as it's absolutely empty

minor update got the welding all finished on the mid pipe and made a blanking plate up for the turbo flange have fitted the backbox and the Z is back on the road so I will be able to use it if needed just need my new silencers to show up refill my gas bottle and I can get on.

I have a few different maps which I tweak on the road using my wideband afr not ideal but not worth getting it tuned until i stop playing

Me too the price tag wasn't so nice though but the ramps are really good

Glad you think it's good my dad popped by earlier and said it looked like bird S**t but he was a coded welder

so I've got a bit done this afternoon got the new takeoff welded on to the mid pipe much better location for the turbo than the previous setups i have tried so far my new ramps are making it much easier as i can actually sit underneath the back of the car this is the exhaust mid section off the car so i can finish the welding hope to get this welding finished after work tomorrow so i can use the car again will just make a blanking plate for the flange where the turbo mounts and bolt the back box back on

Yea I am excited I could do this all day every day in fact I've got a silly grin on my face Just thinking about it

As Alex said which heat shield is it ? the one above the backbox or on the cats The rear one corrodes around the studs that fix it to the floor below the boot just stuck some washers on above the nuts on mine been ok since

Had a couple of hours this afternoon so decided there's no time like the present to start on the Mk 4 ,5, 6 or whatever version of this build I'm up to anyway it's more of an evolution than a different version I was going to do a before and after picture but the missus was menacing me so had to stop playing but you get the idea from the before And the pile of bits a couple of hours later I've put the old Backbox on and it's all drivable all ready to start again

you can pretty much use any 3 wire sensor on the UTEC as long as you have an accurate pressure source to calibrate it from

can't see there's any value in going to the GM 3 Bar sensor i'm not sure what the standard UTEC one is rated to but it's more than enough on a 350 rear mount or is there something i'm missing (it wouldn't be the first time)

Pretty sure it's ok as I've been driving it pretty hard and there was no knocking sounds or marks on either the plenum or strut brace

yea it's only 6mm i think most plenum spacers are thicker than that I could have easily gone up to 8mm

Only just got around to fitting this as I had to use longer studs and bolts but all fitted now doesn't feel any different but plenum is noticeably cooler which can't be a bad thing with the amount of time i spend with my head under the bonnet at the very least i'll stop burning myself on it

if it could be lowered enough so the roof was 6 feet under it would still be ugly so Dan will probably like it as long as it's got a huge spoiler on the back

I'd maybe consider making them but not until I've had it fitted to my car for a few months at least

Hi guys have you seen the phenolic intake gasket made by cosworth http://www.japspeed....gasket-kit.html I liked the idea of these gaskets but didn't like the price also they are only 3mm and from what i've read the thicker gaskets perform much better so after some investigation into materials I decided to make my own since I don't have a plenum spacer I've gone to 6mm instead of 3mm as used for the cosworth gaskets I usually program directly in gcode for my CNC but it was a bit too fiddly to do by hand so had to use Cad which i don't like because I'm a bit of a Dinosaur but after lots of measurements and a good few hours in front of a computer I have this if I charged myself for the time I spent in front of a computer to make this it would be very expensive but since I actually enjoy doing stuff like this all it cost was £20 and an hour on my milling machine I might even get it fitted this week
