Well, in the case of a SOHC motor you can bet that the SOHC head, single cam shaft and lesser amount of gearing/chains etc is going to easily make up for that 28lbs. The DOHC head and cams will be similar, but having cam over valve should save some weight over the SR's rockers etc. The cranks, I wou...

I was asking about this a while ago and couldnt get an answer. For the record, a stripped KA block weighs: http://img.photobucket.com/albums/v133/black240sx/54ea9f23.jpg http://img.photobucket.com/albums/v133/black240sx/322fbf80.jpg An SR block weighed 67lbs. As far as I can see the only difference ...

I didnt end up having time to get my block to the shop before the pistons got here so I sent them with the block, the pistons weren't matched to any of the bores because they were all within ten thou (.0001" )...

Just saying...

Do you order those collector tubes cut like that from somewhere? I flippin hate cutting pipes like that.

IMO you wont have any safety factor at those power levels with cryo treated stock pistons. If anything goes wrong, you're done. To give an example of what a forged block can take, I daily @ 25psi, I boost spiked past 35psi for an entire 4th gear pull, blew up all my spark plugs, lifted the head and ...

^ Good point. By the time you break down the motor, hone the block, grind rings replace everything, the price difference between forged pistons and cryo treated stock ones is quite insignificant, may only be a $200 difference on a $1500-2000 build. Not worth the difference in strength.

How much does it cost?

Im surprised you didnt figure this out from their brand name...

"Godspeed" = "Goodluck sucka"

"Godspeed to you sir"... ie. Good luck getting our parts to fit

Its totally the BOV... I've had greddy BOV"s before they whistle a bit when they barely open. I can make that sound with my mouth, its sounds metalic but its just a whistle.

Looks kinda gimmicky. 12 tiny pistons vs 2-4 large ones. I bet Z32's would be better than these.

I asked for the sheet included with wiseco pistons and got the information. Wasnt interested in peoples speculation. All I wanted to see what the called for bore size for their +.040 pistons and the clearance specs, this is all the info I need to get the block machined/honed. I was worried that some...

I made 349whp with RX-7 460's.

I cant laugh at that stuff, its like laughing at a retarded person's home work. Some people just dont have it.. I havent been to a car meet in years.. i feel sorry for "car guys".... As for the guy who took and posted all the pics... as funny as they are, he's a total prick and I would hop...

Honing shouldnt remove more than half a thou, a thou at most. Once they machine the block they will size the pistons to the bores, which is what I will do. They shouldnt be machining the bores to match the pistons as the pistons will all be identical.

The drive shaft is too small in diameter to make a performance difference. Its more of a curb weight/simplicity improvement. Its nice to get rid of the 2pc stock POJ.

That chrome powder looks alright, im gonna have to get some

I've worked in a machine shop for the last 6 years, there is no way in hell Wiseco is selling pistons that arent within .0001 of what they say they are going to be. Neither I, nor the machine shop I will use will likely possess equipment capable of even measuring how close most piston manufacturers ...

Thank you. exactly what I needed to see.

Haha, you clearly dont know very many machinists.

He will know... based on the measurement given by wiseco! Is there not a single person who is going to respond to this thread who has actually purchased wiseco's and used them for themselves? My CP's came with a little print out on the piston diameters, and what the bores should be respectively. I j...

To give the stock head some credit, i was running it to 7500k on occation without any problems. There may have been some float but nothing I noticed and power was still wicked. I should have my pioneer valve springs this week for my new head, but I still wont be doing mech lifters, the hydraulic one...

Just to explain my thinking.. you can only assume the pistons are going to be the right size. Given the equipment theyre using, a tolerance for a small aluminum rounded part is going to be in the tens of thousands. So its pretty safe to assume the pistons will be 90mm +- .0005 at most. So if I tell ...

Nm.. I think I asked a stupid question, I think I'll be safe having a 90mm bore.

I doubt wiseco is selling pistons that vary in size more than a few .0001's .

I'll be doing the rings myself, the actual specs of the bore are specified when you recieve your pistons based on expansion etc, they should all be the same for wiseco's and this is why I ask. If anyone recently had a block done with Wiseco's they should know the bore specs for given size.

I've daily driven with a cage, but IMO you have to have 4 points. The OEM 3 point will allow you to sit "loose" which is what presents the skull crushing problem. If you're planted in your seat and you have padding on your bars you're probably going to be ok. The cage is no more dangerous ...

Are you saying this because you know them to vary in size or because you dont know and you're being cautious?

Clean build. Very thorough. Good to see some undercoating. Rust free!

I've seen a few knife edges cranks, they werent machined, they were ground. The leading edge of the counter weight was sharpened to cut through the windage/oil. If you have access to balancing equipment, you just need an angle grinder and a couple hours. I personally wouldnt do it though. Seems like...

I ordered a set of .040" oversized Wiseco's, they probably wont be here til next week but I want to have my block machined for when they get here. Can anyone confirm that the bore specs will be fairly exact to 90mm/3.543". I know my CP's were bang on their specs, just wanted to make sure t...
