Yes the rods and pistons are custom. My rods are 4mm longer than stock and the wrist pin is moved up into the oil ring area. I have to run oil support rail rings. If you look closely at the pic I have an extra set of rings there compared to normal. That is why. I did this to get a better rod ratio, and have more dwell time at TDC for better high RPM's.


wow just wow, you have truly developed your package, something very few people do now-days (myself included). you have been through trial and error and developed parts instead of buying and assembly. keep it up :notworthy: :notworthy:


Thanks, it means a lot.

Plastigaged the motor today. Everything looks uniform. Rods have an extra .001" clearance for higher rpm.

All the mains look like this:

And all the rods like this:

I'm coming down with a cold now, so I'm going to take a break on the car for a little bit.

Thanks.

My buddy is all into documenting this whole build, so he took a better pic of the rotating assembly:

Did you get the uprated wrist pins and HD forging? its tough to tell from pics. CP, JE, and wisecos are typically only rated to right at 600hp.

No, it's normal. I don't buy into that. The piston will break before the wrist pin. I haven't ever heard of someone breaking a wrist pin. 2nd the piston truly doesn't see as much heat as you would think in a properly running engine. The boundary layer that forms keeps the heat away. Otherwise all pistons would melt. Plus I have my coating as extra protection. The only advantage I would believe is if there is more material around the wristpin hole, in the piston. Giving it more strength there so it doesn't split in half at the wrist pin location.

My pistons and pins are CP but I am using JE rings. I'm on the same piston set since 2003. Not sure HD stuff was even out then. I have ruined one set of rods due to that little c-clip popping out of the oil relief valve at 9000rpm. That turned all the rod ends that go around the crank black. If you guys want a picture I can post it of the carnage. That is why I did the allen npt plug. I ended up buying a brand new 3S block to redo my motor. The block came with the 98+ 5S corner by the water pump. So I thought I was in the clear. Got my Alltrac running on the GT4088R. After just shy of 2,000 miles I cracked it between cylinder 2 and 3 inside of 2. Got a junkyard 5S block and pulled the freeze plugs. Pulled the plugs on my 3S to find that Toyota runs a webbing between cylinder 2 and 3. The 3S block stops half way up to allow more coolant around the cylinder at the top, where the 5S one runs the whole way. My crack was exactly where the webbing stopped. So now I am running the 5S block with it half filled for extra support. My 3s block cracked with a 1mm over bore. With the coatings this time and doing the normal my machinist likes to do .005" piston to wall clearance, my bore is 3.437" or 87.3mm. We'll see how it works out. All of this has happened on the piston set I currently have. If i got a new set I would raise my compression. Right now I am at about 8.4:1. I would change it to between 9-10. If I had an E85 station close to me, 10 would be the minimum.

Awsome built. Lots of work you put into it. Keep it up. Hope you reach 0r even exceed your goal.

Water/meth injection in there? Why not? You seem to have a reason for everything so why not water meth

That I have never looked into it. I'm not sure whats better water/meth or E85. I guess I'm old school on my train of thought. I like to fill my tank with one type of fuel and that be it. Right now my main fuel used is 110 octane VP race gas. I can pump it in my car at the station down the road. If I ever make it to the dyno/track, I'll be using an oxygenated fuel like Q16 or VP Import.

If I start to drive the car more than I figured, I'll look harder into water/meth or buy E85 in bulk.

it's windsheild washer fluid. water drops your intake temp as it changes to steam, and methanol does the same but also increases octane. i don't think it's fuel specific though because i first saw it in a diesel magazine, now i see it on cars every once in a while. it's cheap and pretty easy to tune for, especially if you use it with a WOT switch.

and you don't put it in with fuel, you inject it post intercooler, usually right before the throttle body.

1) you don't want to use washer fluid, especially if you're using it as a part of your tune as you have no clue what the mix is. 2) most people use it as an extra safety factor, not as a part of their tuning

i'm not saying to use it if you want to be precise about it, there still needs to be room for error, but if you head to the evo/dsm forums, they have been using it for a while with up to 50whp increases using water meth. diesels go back even farther.

an easy way to tell the methanol concentration is to look at the temp it's rated to. i think 50/50 is like -40f blue stuff

Looks really good, but there are a few parts i would change\drop:

1: the crank pully ( from what i have seen, those do not have any harmonic balancing? would def use the stock one.
2: why do you need a fenspot overdrive powersteering pully ? ( waste of money!? )
3: don`t use the nology plug wires! they SUCK! ( try to lett the car run in a completly dark room and you will see why.. )
4: would use stock crossmember bushings, you need a little flex somewhere to keep drivetrain in one piece
5: if possible: try to get a thicker "stock" copper radiator.
6: don`t think that hks clutch will hold 700awhp..
7: get some poly bushings for rear sub frame. ( need some form of flex. )
8: would def use the 6466..
9: moroso oil pan.

I think this will be a NASTY car. and i am by no means trying to be a asshole here... just trying to contribute with what i have experienced tru the years of tuning..
