Nice glad I found this thread, keep the pics coming. Subscribed

Nice seat

Nice progress a bit more weight in it now from when I saw it

Rear ARB looks very nice all powdercoated..

Some details on that rear stab. bar please /Woj

Some details on that rear stab. bar please /Woj

The rear anti-roll bar is a modified 19mm anti-roll bar from the front of an MGF shortened and welded together.

Its held in place with front Cento anti-roll mounts and bushes on custom made mounting plates welded to the rear beam.

It is then fixed at bottom with Lancia integrale EVO1 rose joints (any rose joints would do but had these at hand) with custom made mounting brackets fixed to the bottom damper bracket, this will be further modified so the bottom of rose joints is at least in line if not higher than bottom of the damper to give better road clearance.

Once its painted up we'll get some pics of the custom mounted where the battery used to live Grande Punto expansion tank, and how much or how little clearance we have between the top pulley (this is a vari-cam thingy so bigger) and the headlamp unit, its about 15mm all round, but as engine moves backwards under load should be fine. To further protect against this the engine mounts have all been uprated using Tiger Seal which is polyurethane, can't quiet believe how stiff they are compared to normal, can barely move the engine.

Forgot to add this picture in an attempt to show the spacer we made to move the engine mount over away from the alternator belt. The mount itself is also modified to increase the clearance.

Hope you dont mind me asking but are those cambelt tensioners completely automatic? You just bolt it on and done?

 

[randomizered]

Yes, it is spring loaded with a tension mark.

You tension it with needle nose pliers, or the special fiat tool, torque up the nut, do two whole rotations of the crank, and check the tensioner mark still lines up, if not repeat.

That one in the pic is not teneioned 100%, but is pretty close. it can be a big pain to get it bang on

Thanks for the info Kristian I see how it works now
The one on my 1.4 12v was a really nice design I was very impressed with it. was no problem holding the right position when you tighten it.

Not many updates, but it is getting ever nearer completion.

Still waiting on the Sparco roll-cage to arrive from Italy, Aug shut down doesn't help, but hopefully soon.

The exhaust has been made, with a rather cool exhaust hanger bracket fabricated to be part of the anti-roll bar brackets on the rear beam as we removed the original exhaust hanger from there to accommodate the anti-roll bar.

A full set of Punto HGT brake callipers have been bought awaiting arrival, and I'll soon be ordering some Pinto HGT brake disc's as the fronts are slightly thicker than Punto GT ones 22mm V's 20mm which seems like nothing but makes a big difference to price, but will dissipate heat better. Also have the option of fitting a set of Wilwood front 4 pot callipers as recently purchased some massive Mitsubishi GTO 4pot brake callipers and a 325mm brake disc conversion for Emma's FTO which at present runs the Wilwoods with a 297mm EVO4 brake disc conversion, the Willwods say min disc's size is 250mm which puts them plumb into the HGT disc size territory.

But biggest update really is ECU choice which was up until now going to be Emerald as we used in the Seicento to good effect. But a while back I noticed a new ECU to hit the market which has been getting advertised a lot in mags trying to increase public awareness, so looked into it and liked what we saw, so we are one of the first to try it out and as such got a very good deal, in fact too good to be putting on public forums! Its http://www.canems.co.uk for anyone interested in that stuff.

I will try and get some pics over the weekend for updates.

why that one over Emerald? Was it the built in data-logging that swayed it? Does it only support the 36:1 trigger wheel too ??

Hi Mark,

The data logging facility is pretty good, given as the cars being built for track days. To quote the website "RPM input from either VR or Hall effect sensors with 36-1 or 60-2 toothed wheel"

Few reasons really, its built inside a water proof Bosch type ECU case with Bosch type connection so can be fitted under bonnet like OEM Bosch, it also has ability to use all exsisting sensors as these are all configured for Bosch ECU's. We can also use the Emerald map from the sei and in Chris's words move stuff around to suit for a decent base map before it goes on the rollers for proper set up.

Aaron.

coolio.

i did look on the website, but could only see mention of the 36:1 wheel - guess i should've looked further into it. I like the casing on it, and noticed it has internal relays for fuel pump etc. re the sensors, did you not do that with the emerald? or did that require changing some of them? I know mine runs the sensors the engine came with (wideband lambda asside!)

 

[J333EVO]

The Emerald ran all the sensors we had on the Sei, though we did use a K-series throttle body and sensor which the Emerald was originally deisigned for in Kit-cars, Se7ens etc

The internal relays etc are a good feature, though on the Sei we just used teh standard ones which were powered by the Emerald TBH i've not really looked into it all, its moved pretty quickly from seeing an advert in a mag to receiving one

What sort of price range do they start from? Are they able to run wasted spark etc?

If they are good I might be interested in one instead of a MS unit.

Thanks

 

[randomizered]

About £225 with the loom and all.

About £225 with the loom and all.

from the website, that is just the ignition ECU.

The full ECU is £429.95

 

[randomizered]

Ah, thought it was cheap

 

[fingers99]

Excellent work, as ever. What did Jon do about the VVT in the end? I see the plate covering the wart, but.............

 

[arc]

its not really VVT, just alters the exhaust cam on startup to heat the cat up quickly.

iirc there is a plate made up with two channels in it, depending on which setting gives the most power deciedes which channel the oil will be left flowing through!
