I guess I reached the limit of the stock pistons - this isn't the one that had the damage from the valve dropping...

Did you do any mods to the top of the block to stop it flexing between each bore?

[maciekb2002]

damn .That is actually hard to believe .
How many miles since you build bottom end. probably dents from meeting the valves wasn't helpful too

No, I didn't, I'll do that on the next block

About 40K since I built the motor, so not too bad considering the abuse it has taken, but still.......

Surprised it lasted as long as it did without filling in the blanks.

For some reason I sense a bit of underlying joy in the fact that you get to build something better But still.... that does suck. I cryo treated OEM pistons ect, so Im hoping that will aid in what they can handle. Getting the block, crank, rods, pistons ect ect cryo'd might be a good idea for the new build.

And when you start going north of 400hp, its good to sleeve these aluminum blocks.

Sure - it keeps me busy

I'd rather have done it on my terms, but hey, I think it was inevitable something would break, since I have kept upping the ante.

Someone else mentioned cryo treating everything - not sure though - there's certainly nowhere local, and I'm not sure I want to get involved with shipping the block, etc, all over the country...

I have am '04 2.3 HPT block lined up, I should be able to get it in February, then move on from there - bore seams filled, new pistons, bearings, etc..

[maciekb2002]

Was only 2.3 HPT block mounted in c70s . If I am not mistaking s60 were all 2.4 +

All I can say is with the weekend track events racing the Vettes over the years, everyone I know that cryo treated the motors will never look back.The motors run cooler and last longer, as does the brakes ect. Most guys tear down after a season, now they run 2-3 seasons.

Maciek - the block is coming from an '04 HPT C70

That's not far at all, thanks for that!

I'm gonna have to do some reading. Does the treating get done after or before the block is honed/bored? I'm assuming after - but doesn't the treatment affect the bore dimensions in any way?

[thunderbirdsc]

Treatment wouldn't effect the dimensions.

Basically you are super cooling the metal to force the remaining austenite into martensite in the crystal structure of the material.
Normally this process will increase strength and hardness.

Im not 100% sure with the before or after. Give those guys a call and drill em with any questions you got. Ask them for proof or feed back.

Heres where I go http://www.cryo-ice.net/ I know the owner and his son. They have some nice info on the site if that helps. Also note that alot of racing teams, Nascar ect, are using this but staying hush hush about it.

Valves have plenty of space when set in the correct position.

Why not order non VVT style cams and use the non VVT gears? much more solid and also better fixed construction...

Since the motor is coming out for bottom end work, I just conversed with Jan @ Enem, and he is going to send me a set of replacement Y21 cams, with the solid (Non-VVT) gear design, so I can use the early gears & not worry about the torque required with VVT hub design. He did say they have revised the design so that the slotted end is dowelled in place, instead of just pressed on. Switching to the early gear will also make it easier to setup the cams at the lift they specify - I can mark the gears themselves.



While the motor is out, I will also address:

the alternator lower bolt/breather box issue
redo my secondary can in aluminum
port the exhaust housing somewhat
install the KU single mass flywheel & Spec clutch

Cryo treatment? maybe..

I would love a set of cams for an RN head that utilize the old style cam gears! They're so much easier to set!

Jardim besides tune is your head stock to be able to run up to 7500? I see you've done injectors and and a tune to support fuel and ignition that high but curious to see what else you have done to reach those RPMs. I'm on a Rica stg 3 tune white's and a 16T I haven't tried to reach the rev limiter but I assume there is now way my war would go another 1000rpm over stock.

BRB, LOLing forever.

hahahahhaahha.

WOW minus the various typo's and lack of rereading before submitting the comment I also clearly put in the wrong User name.

I = FAIL lmao

OK - enough already. If you want to continue OT - take it to PM's or start you own topic. No need to reply to this.

Thread on Turbo sizing, etc

Worked on the water pipes for the Tial 44mm. Added -4 AN fittings to the main water pipe & to the oil cooler return/block drain line. The PTE is oil cooled only, so no need for the water ports.







Enem Cams are here



Turbo is here



'04 2.3HPT block is here, stripped it yesterday & dropped the block, carrier, pan & hardware off at the machine shop. If he can switch the order with JE - I'll go with longer H-beams from RSI, and short forged pistons. Apparently the rods have a non-standard small end - 22.8mm, so either they have to be re-bushed or different gudgeon pins have to be made.

Hybrid turbo is already sold. 139.5mm H-beams will be up for sale, too if I go with longer rods.

[fischmama]

I don't have any issues bridging the two ports with a good heater hose. I also had them blocked for a while. Both options worked fine.

BTW, that turbo looks gorgeous.

[Jardim]

Jesus i don't belive what im seeing, thats what i call plan into work.

Good luck Hussein!
