89tsi20g Posted September 6, 2003 Report Share Posted September 6, 2003 i really want to get 8.5:1 pistons, it is still kind of a low compression anyway, if JE can do them why not Wieseco? i'll be running Tim C's roller cam, Rob NJ. Quote Link to comment Share on other sites More sharing options...
Conquest Posted September 6, 2003 Author Report Share Posted September 6, 2003 tad -- Don't worry. You're alright. ;D Rob -- I am working with them on this and your blok may only need to be decked a little if we can't avoid that at all, but I believe that JE was not a TRUE 8.5:1 also.

Conquest Posted September 18, 2003 Author Report Share Posted September 18, 2003 OK. I just wanted to let everyone know that I am sorry for this taking longer than expected, but that I was given a completion date of approx. October 6th Just remember that it took longer because these pistons are being custom made by Wiseco and are an ACTUAL 8:1 and 8.35:1(the closest to 8.5:1 without valve reliefs). Â The full 8.5:1 can be attained by soem simple block decking, which should be planned anyway. Please let me know if you guys need anything else or have any questions. I appreciate your patience for allowing these pistons to be done the right way. ;D Quote Link to comment Share on other sites More sharing options...
importwarrior Posted September 22, 2003 Report Share Posted September 22, 2003 if you deck the block the valves will still hit wont they? if the top of the piston is higher to gain 8.5:1 CR that means valve reliefs need to be done to the pistons? correct? well if you do not valve reliefe the pistons. and deck the block, your actually lowering the head closer to the pistons when at top dead center. this would make 8.5:1 . then how is it the valves will not hit the pistons when you are decking the block. i believe the pistons would need to be reliefed in either way if you want 8.5:1 NOW why is it that a caravan can run 9:1 no problems but we cant run 8.5:1 ?

Conquest Posted September 22, 2003 Author Report Share Posted September 22, 2003 Yes, that is a concern. Anytime you are physically moving a piston closer to a cylinder head, piston to valve clearance should be checked. The problem being with these engines is they don't have valve pockets to begin with and we've never had anyone give us location or even state that it was a concern. I did look and we've done one set of absolute flat pistons for a customer-we never heard anything back from him in terms of clearance issues. The clay method is about the easiest way to check, and I'd consider doing that before someone decks their block. These pistons are thick enough that a customer could fly cut if necessary, but there's an easier way to check: Pistons are closest to the valves at up to 11 btdc on the exh. and 11atdc on the int. If one figures out where the cams are when the piston is at that point, you can degree the cams to that point and measure where the closest part of the valve is to the deck of the cylinder head. I would expect with this cylinder head that the valves still don't open below that deck surface. It will give you a very close idea of what the clay check would tell you. As for compression, I'd agree that 9:1 is a possibility with a lot of turbo engines. Most hondas are that way now and about 1/2 the Mitsubishi 4g63 owners choose our 9:1 piston over our 8.3:1 version. Many new factory engines are starting at 9:1 and in our serious race pistons people are going much higher than that w/ race gas or methanol. I understand your arguments exactly, but I am going by the Wiseco contact using our factory measurments and what some of the pros here have stated.

eeaston Posted October 5, 2003 Report Share Posted October 5, 2003 Anyone order and want to back out? I just entered the market for a set. Quote Link to comment Share on other sites More sharing options...
Conquest Posted October 5, 2003 Author Report Share Posted October 5, 2003 eeaston -- They should all be done around October 6th, so they will be received by everyone sonn, but I can probablt work a deal out for you. Quote Link to comment Share on other sites More sharing options...

eeaston Posted October 6, 2003 Report Share Posted October 6, 2003 Awesome. It'll just be a few days til I can get my head torn off and mic the cylinders to see what I'll need. Do you know what the recommended BORE diameter is for each oversize(.032 and .052)? Including Wiseco's recommended clearance? Thanks.

Conquest Posted October 6, 2003 Author Report Share Posted October 6, 2003 Sorry this is taking so long. It took a while for Wiseco to get teh right specs on paper for TRUE compression ratios. Wiseco said they should be done by today and yuo guys should start receiving them soon. Again, sorry for teh delay, but its worth the wait.

Conquest Posted October 7, 2003 Author Report Share Posted October 7, 2003 eeaston -- 3.622 AND 3.642 respectively. The clearance of .003 is built into the piston. Oscar and Tad -- Yours were sent out on the 29th of September. Rob and Abbas -- Yours weren't drop-shipped straight from Wiseco and went to supplier first. They will be shipped to you as soon as they reach supplier. Any day now. Quote Link to comment Share on other sites More sharing options...

Conquest Posted October 12, 2003 Author Report Share Posted October 12, 2003 eeaston -- OK. I can get you the Wiseco forged pistons in only 8:1 since it is not in a group and it will be $435 shipped. Lert me know what you think. Thanks Jim Quote Link to comment Share on other sites More sharing options...
eeaston Posted October 13, 2003 Report Share Posted October 13, 2003 Jim, I appreciate the help, but I just closed the deal for Superquest_t61's built motor, so I won't be rebuilding mine now. Again, thanks for the help. Quote Link to comment Share on other sites More sharing options...

89tsi20g Posted October 13, 2003 Report Share Posted October 13, 2003 i was just thinking-since we get those weird oversize numbers, who the hell is gonna have headgaskets in those sizes? Rob NJ. Quote Link to comment Share on other sites More sharing options...
Oscar_the_Grouch Posted October 13, 2003 Report Share Posted October 13, 2003 i was just thinking-since we get those weird oversize numbers, who the hell is gonna have headgaskets in those sizes? Rob NJ. Hey Rob I am with you on this.... Since we both went with the 0.032 bore, I think its close enough to the 0.030 RIGHT ? I am no mechanic so I have no clue. And just a curious question.... if JE and the others offer a 0.040 over bore why did wiseco had such a hard time locating rings for their 0.040 over bore ? But I guess we will need to get in contact with Wiseco and see what they say about head gaskets..... BTW i got my set on Friday... They look GOOOOOOOOODDDDDD ! Sweet set of pistons..... LIGHT as air too. And man they almost look like flat tops, only a small Dish is barely shown. I can shave by looking in them thats how shiney they are.

Conquest Posted October 13, 2003 Author Report Share Posted October 13, 2003 Glad you like your pistons, Oscar. I told you they would be worth the wait. As for the bore size, I am not exactly sure why JE has no trouble finding rings for .040 over, but it may be that they have incorrect specs for the pistons just like Wiseco did before I gave them the right ones.

89tsi20g Posted October 15, 2003 Report Share Posted October 15, 2003 OK, so who's gonna have gaskets like that? i do not want to get stuck with pistons i cant use cause nobody has a headgasket for it, any thoughts/ideas guys?

Conquest Posted October 15, 2003 Author Report Share Posted October 15, 2003 Wouldn't it be easy for a machine shop to cut the gaskets to the right bore size? Quote Link to comment Share on other sites More sharing options...
Kreal Posted October 19, 2003 Report Share Posted October 19, 2003 Wouldn't it be easy for a machine shop to cut the gaskets to the right bore size? Head gasket should not be a problem...You should be able to go as big as 060 on a stock bore gasket. DAD Quote Link to comment Share on other sites More sharing options...
