wondering whether a thread like this is of use? (to Andrew in particular)
the thread would consist of informative one liners giving useful/imperative information surrounding the rebuild/modifcation of the gordini turbo cars. the comments would be 'up for discussion' and I would edit them according to peoples experiences. This would help people like me who do not have the advanced knowedge/experience of andrew, phildini, sparkie, mark fish etc. etc. (sorry if i left you out)
- a higher duty oil pump can be sourced (from mecaparts for example) this is a worthy upgrade and can be changed with the engine in the car (just drop the sump). This will help your turbo and keep the engine happier. a higher duty oil pump is not available from mecaparts for the gordini turbo, only for the non turbo.
keos/keops racing did show one they made, but i dont know anyone who has ever contacted them about it - http://keops-racing.skyrock.com/ http://keos-racing.skyrock.com/
- When sealing the cylinder liners it is advised to use high temp silicone in addition to the o-ring seals, this should be applied by..?smearing your finger over the OE liner seal and fitting the head as quickly as possible - then leaving it for a good 12hours for the stuff to cure. - do not use sikaflex or tigerseal - you'll never get the liners out again!
- when using a 1.9mm head gasket (to increase boost/account for head skimming) you must use 12.9 headbolts, increase the carb jetting and ?
must you use 12.9 bolts? who told you that? - the gt turbo crowd use them cos they are cheap to buy. you can only increase the carb jetting so much, before the high compression of the gordini turbo lump causes the car to detonate. - fitting gt turbo pistons will stop this up to a point, as would fitting a really lumpy cam. the only ways after that are water injection, inline chargecooler/intercooler or gt turbo conversion
- Water injection is a proven system to increase realibility and power by reducing the raging engine temperatures and providing a more dense fuel/air charge. yes, but you do have to keep filling the bloody water tank up. you can get em cheap from here: http://www.aquastealth.com/
- the GTT inlet manifold upgrade is a worthy, proven upgrade but it will protrude through the bonnet a touch (?) its not the gt turbo manifold that is used, but just the gt turbo carb mounted on a machined down gordini turbo manifold - with a flat plate welded on and solex pattern studs fitted. - it does foul the bonnet in most cases though
- search mr dini's post to source ht leads which do not require the unecessarily complicated and expensive spark plug extension caps i used nissan micra (k11) plug leads - they were a fraction longer where it fits into the engine and also the lead length was slightly longer too, but i got a magnecor set from a scrap car.
- the oil cooler circuit has threaded fittings at the engine end and jubilee clips at the oil cooler, which seems silly true, but it just means its easier to fit a larger oil cooler?
there will be lots lots more... please chip in and help me and others.
