Wez Posted February 12, 2009 Author Share Posted February 12, 2009 I will find out if they are willing to do a smaller group buy. Quote Link to comment Share on other sites More sharing options...

Wez Posted April 24, 2009 Author Share Posted April 24, 2009 Now worries matey, its a shame we couldnt get all the numbers needed Quote Link to comment Share on other sites More sharing options...
Wez Posted January 22, 2010 Author Share Posted January 22, 2010 I have found another contact for Cosworth which has now answered most of the questions raised earlier 1) Could they be made with oil galleys like the stock piston as the 2JZ-GTE has oil squirter's to aid cooling? Do you mean cut outs in the skirt to accomodate the oil sprays? Yes no problem, but we would need an OE sample to measure from. 2) Will the gudgeon pin diameter be the same as stock? 22mm pin as stock and yes they will. 3) Can they be low friction/anti det coated? There is a low friction bedding in coating included in the price quoted on the piston skirts. The Crowns are mirrior polished to help anti-detonation, again included in the price (both of these are normally cost extras). 4) Would the valve relief be large enough for +1mm valves? Max valve size allowed is 33mm Inlet, 28mm Exhaust 5) What is the Crown volume? Do you mean the Bowl CC? 6) Is 86.00mm, 86.50mm and 87.00mm available, if so in the same batch? Yes, all available in the same batch. 7) How much do they weigh? Depends on bore size. As Cosworth have not made these in a while (using the new forging at least) they are unlikely to be able to give an accurate figure today. If there is sufficent interest (ie orders) then they can do a more up to date model which will give them a predicted weight accurate to about 98%. They will only take the time to do this however if it looks like they will sell some. Im sure you can appreciate that considering the time involved in redrawing pistons and the number of enquiries, it has to be on a priority basis. 8) Are low compression versions available, if so can they be done in the same batch? After the initial batch of 48pcs is done, further pistons can be low comp. >48pcs as oe. 49pcs> can be low comp so in short, you will need 8 OE comp ratio customers before the low comp orders can be processed. OE comp ratio by the way is 8.5:1. As long as you dont go lower then about 8.0:1, this shoud be possible but I would need you to come back to me with firm numbers before I can say for sure. 9) Is the compression height same as stock? Compression height is same as stock. Quote Link to comment Share on other sites More sharing options...
Steve Posted January 22, 2010 Share Posted January 22, 2010 Wez, if you wanted a OE piston so they can measure the oil galleys let me know. I still have my old ones here which they can have. IF not they will be going in the bin. Quote Link to comment Share on other sites More sharing options...

Wez Posted January 29, 2010 Author Share Posted January 29, 2010 Any interest in this then? Quote Link to comment Share on other sites More sharing options...
Wez Posted January 29, 2010 Author Share Posted January 29, 2010 Guess no one is interested in some Cosworth pistons then Quote Link to comment Share on other sites More sharing options...
Wez Posted January 29, 2010 Author Share Posted January 29, 2010 I have been speaking to Cosworth about 2JZ-GTE pistons. These would not be the older JUN design but a much newer forging. £750 per set +VAT The price includes six pistons( 86.00mm, 86.50, or 87.00mm) with rings, pins, clips, skirt coating, anti det bands and polished crowns. Will the gudgeon pin diameter be the same as stock? 22mm pin same as stock Would the valve relief be large enough for +1mm valves? Max valve size allowed is 33mm Inlet, 28mm Exhaust Is the compression height same as stock? Compression height is same as stock Anymore questions let me know and I will fire them at Cosworth. So whos interested, need a min 8 sets? 01. Wez 02. 03. 04. 05. 06. 07. 08. Quote Link to comment Share on other sites More sharing options...
Wez Posted January 31, 2010 Author Share Posted January 31, 2010 Zero interest in this, I will take two sets which means we only need another six to get the order processed Quote Link to comment Share on other sites More sharing options...
Wez Posted February 1, 2010 Author Share Posted February 1, 2010 I take it this is a none starter then, ahhh well Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 1, 2010 Share Posted February 1, 2010 Thanks for trying Wez, it's the 87.00 mm that'd the problem, nothing like big enough, interest here starts at 19 inch minimum, preferably 20 inches Quote Link to comment Share on other sites More sharing options...

Miguel Posted March 27, 2010 Share Posted March 27, 2010 I can't believe no one is jumping on this. If I was still toying with Supra's I'd be all over it for a couple of sets. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted April 1, 2010 Share Posted April 1, 2010 Wes, is it worth advertising on the US Supraforums? Hopefully get a few more then. Im not really in position to buy just yet, but i am interested. Out of interest, how do they compare to CP in terms of weight and strength?

I will refresh everyone's memories and get back onto cossie after the easter holidays if there is enough interest. Quote Link to comment Share on other sites More sharing options...
