[car_overhaul] Zx 16V Project Pt2, Re-Shell And Power Upgrades....

Sure they will. So it's not a big issue.

But ideally you should change the pad then when it is still a little bit more material left than compared to a 28mm disc.

 

Also the 28mm disc can probably wear down to 26mm legally, so as long as you keep an eye on it I can't see it beeing a problem.

I sold the engine to Blandy back in December, as I had happened upon the basis of a full engine build, in the form of a Block and higher compression pistons.

 

The last few months have been a battle of collecting bits, deciding what direction to take it and budget constraints, and making it work with what I already have to hand!

 

Currently, I have a big jigsaw puzzle, almost ready to assemble, crank has already been fitted and plasticauged, along with a Conrod and piston in to check deck height and valve clearance.

Decided to paint it a striking colour

Big thanks to Carl Robson and Sandy Brown for helping out with the conrods, also thanks Sandy for the pointers in what to measure.

 

Also Ed and Steve at Warners for supplying the o.e parts at very good prices.

I'd use a straight edge and feelers to check the piston to deck height, I've done it that way with the dti before and not got repeatable results.

I know what you mean, the piston can rock in the bore if there's a bit of wear

Final Parts for the bottom end I think, thrust washers, had been on backorder for about 6 weeks.

0.13 of a mm, ideal, tolerance is 0.07 to 0.32mm.


Further progress is at a halt till I make/earn more money, as the head needs checking over and the seats cutting

so, an update!

 

took the head and valves to South Wales Pistons for them to check the face and guides and cut the seats and valves.

fitting the springs and collets, what a faff! dab of grease helps, also not having the cam ladders gives and extra inch or so of clearance, I wrapped the head of the spring compressor in tape so the lifter bores weren't damaged.

 

27185868712_3211e1c00c_c.jpg

Standard clutch fitted, will see how it copes with XXX amount of torque, I don't tend to abuse my cars so probably just fine! starting to look much more like an assembly, less spare bits kicking about

however the peugeot sport Group N Decat twin tube downpipe had a sleeve fit end for a magnex catback, also pretty small here at 2".

Not quite yet, I measured the lengths and did a few calculations with the help of a few tables i found and they may work very well with a decent pair of secondary pipes.

 

next update will be mapping hopefully!

just realised I hadn't dropped the pics on here that I posted elsewhere, cso the start of this post is from september.

 

 

I decided to buy some brakes.

Thats a saxo vts/xsara vtr Indianapolis wheel without any spacers, 205 speedline needed 3mm, no cyclones to hand.

Pro race 1's, Direct pug fit, not the grey ones that don't fecking fit that Bowen sold me, tit.

And faff with the cooling system to get cleaner colder air to the trumpets without having to use an airbox.

205 rad and Spal 9" pusher fan, couple of brackets made up from stuff I found knocking about.

28434288943_6a49f87b98_c.jpg
20160809_175628 by WELSHPUG, on Flickr

A bit of plastic coated aluminium and foam board

Need some pipe adapters as the top hose is a different diameter and I'm keeping the heat exchanger, so needed to tee into the bottom of the rad, looking to source probably a 406 expansion tank and place it on the chassis leg in front of the PAS bottle.

 

 

this was the final version of the rad bracket.

Tigger Dave at satchell engineering welded these bits of pipe up for me.

 

29638341605_9d69c8755c_z.jpg29527513452_536285679e_z.jpg

 

 

got a 205 expansion tank tucked in behind the headlamp and its working just fine.

They do look mighty short but are actually 50mm, the length is to suit my total inlet tract vs cam profile and stroke etc, I let Colin do the maths.

So a few weeks ago I borrowed a trailer, and my BMW's alternator died on the Thursday evening just as I was loading up the ZX ready for the Friday morning trek to Launceston, cue DCC's Landrover to the rescue!!

 

this was the view at about 6.30

9.30, That sign, a very welcome one.

 

32702918284_0d0ff41f2e_z.jpg

Bumper off and strapped down.

 

33389685632_7ff88884d5_z.jpg

Dan popped down to Truscotts and got a brand new expansion tank cap, the used one I had didn't seem to be holding much pressure, though it wasn't boiling over at all.

 

big thanks to Neil, he's a bloody good teamaker, as well as Pinto building machine, I'm sure he knocks out two or three a day at least of the hotrod high power beautifully finished engines!

 

oh and Dan picked up some bits from Sandy...

 

33389686722_ce4aa4ef04_z.jpg

After a few issues with some tricky to find wiring faults causing an injector to not fire, Sandy cracked out his wiring kit and made me a new outer injector sub loom, cleaned the plugs and got cracking, then found an issue with the lambda dropping out, seems the heater circuit was a bit iffy and the lambda kept going full lean, gave that a clean stronger live feed and it seemed to be fine thereafter, once the few niggles were nailed down the map came together very quickly.

 

33505656266_b8f6c93146_z.jpg

Sandy Brown mapping the DTA S40 ecu on my XU12 Citroen ZX 16v by WELSHPUG, on Flickr

 

only managed to get a few short video clips, no power figure yet but we do know we're at the limit of the GTI6 injectors at 3 bar (running up to 85% duty IIRC), and the Clio 250cc are filling the rest as required, so its around the 240 bhp mark.

 

next jobs are to sort the clutch cable as it seems to have been cooked with the prolonged periods under load on the rollers, will need to find some material to protect it from the heat, buy some pads and fit my brakes.

Where's the dyno chart? I'm more interested in the torque curve.

no chart, old skool rollers, all it has is a Pair of Dials, wheel speed and power.
