Post #2
There were some goodies included with the car: a full leather ph1 interior, heavy duty rear beam with 25mm torsion bars, a 30mm arb and an option to adjust camber (this very axle has been used in some track series in Germany in the past), wishbones with new poly bushes, xsara vts quick-steering rack
The leather interior will go to my S16 because it has a GTI-6 interior at the moment so they will be swapped over. The special rear beam is not on the car. There is a GTI-6 axle on there now and I also got several normal GTI-6 axles and one from a VTS alongside the car. The VTS rack will go on this V6 project so I can turn normally (and quickly!).
I pretty much know the drill about fitting a ES9 to a 306 (I think I have read all the threads here): cope with the timing belt side upper engine mount and shorten the driveshafts. I will be using 306 outer joints with 406 inner ones and either I will have the shaft between them cut and welded together at right lenght or I will have a new shaft made in right lenght with 306 splines on the other and 406 splines at the other end.
As I have several 406 shells available I will be removing the engine mount support bracket from the suspension tower and fit it to the 306 along what is needed to cut and modify on the chassis legs. 406 V6 radiator will be used and the engine will be controlled by a yet unknown aftermarket ecu. I will delete the front cats and I will only use one pair of (wideband) lambdas.
Gearshift linkage will be done with fully 406 parts fitted to 306, clutch hydraulics will be a compilation of Xsara HDI master cylinder along with the 406 normal parts. Accelerator pedal will use the system from a 406 (which is used in 306 HDI also) where a cable runs from the pedal to the engine bay where a sensor reads the position and then gives this information to the ecu - as the ES9J4S is drive-by-wire. I have these parts ready - just hoping an aftermarket ecu understands this signal, if not then I will have to come up with something.
A/C will be removed from the engine as the GTI-6 shell is a rare one and doesn't have one.
The plan is to free up all the potential which has been tied up by the emission gadgets by running it on standalone management and because I don't wish to jam multiplex bsi unit etc 406 wiring harnesses inside the dash just to get the engine running. I know a few fellas who wire in and install aftermarket ecus they sell - I will ship the car to them so they can tackle the hard part to get it running.
This is something that has never been done here in Finland before (at least road legal) because the regulations were so tight. Before you could fit an engine with displacement of 1.25x over the biggest one used in the model series (2.0->2.5 in 306 case) and have the power of 1.2x compared to the most powerful model. Now they are removing the displacement restriction and they are bringing back the power/weight ratio they had before.
The project is on the starting line, I have the shell, I have the engine, I have lots of parts. I could and will start doing something with this soon and that is one of the reasons I started this thread - to keep me motivated as I am quite busy (I do run a repair shop of my own as my work) but still I want to get this done.
