anyone see This Thread on Honda-tech.com? its a guy from thailand. he is selling a toyota 1G-GTE piston/B16 rod combo. he is saying with this a block guard, good feul management. you can safely run 1.0-1.2 bars of boost on the D16 motor. i think we could use the pistons on our D17 becuase its the same bore 75mm. but would the rods work? he says the bottom of the D16 needs to be shaved a bit to make enough clearence for the bottom of the beefier B16 Rods. i think stroke on the D16 is 90mm and 80mm on the B16. ours is 94.4mm i believe. he has pictures n stuff through out that thread.

would this work for us? being as D16 n D17 are basically the same. this would be great because turbo is becoming more and more common on the D17's. would also be great becuase we wouldnt have to get custom rods/piston done to run higher levels of boost.

i dunno feel free to correct me on anything i said. what u guyz think?

So for these rods to work we would have to shave 14.4mm from our head?? This sounds like a lot. Thats just a hair over a half inch (.57168 to be exact). I'm probably wrong on this, but that seems like it would put too much compression on our little motor and it would go boom, especially if you had a turbo. We better let Grey answer this one.

hmm im confused.. since the toyota 1G-GTE rods are flat and the B16 rods are shorter wouldnt this make our compression lower? hence making it good for boost?

(*im not a motor head or anything but i said the above assuming bore means size of the piston [which is 75mm on the D16 and D17 motors] and stroke means lenght of the rods)

the guy is also saying u shave the bottom of the block not the head.

Aren't our pistons oval shaped?

I just realized I was thinking assbackwards. You're right it could work

yes from what i understand ours is oval shaped. and the oval shape is to mix the fuel and air more completly as to having it totally combusted. and not left over and spouted into the air. its something to that effect. its a emmissions thing.

i would think that the oval shape pistons are bigger (in height) making for a higher compression ratio. flat pistons would be less tall and lower the compression. i think this is the case. not sure.. still learning about this engine stuffz [IMG]i/expressions/face-icon-small-tongue.gif[/IMG]

the pistons are NOT OVAL. they are ground a certain way which is called CAM GRINDING which makes them perfectly round when at operating tempurature after the piston expands.

by 'oval shape' i mean just the top of the piston is dome shaped. so you are saying its not dome shaped?

so are the d16's pistons the same way? cause that's what matters.

no...the pistons are cam ground around the skirt.

anyone else wanna throw some knowledge down?

I imagine if the B16A rods would fit on the D17 crankshaft with strong enough bearings it might work. This is assuming that there is enough material to remove(notching) without weakening the casing. You basically have to notch it so the rod wont hit. Perhaps the guy who recently installed a turbo on his could shed more light as to what he used for rods and pistons for the D17, though I think he's only running a small amount of boost in comparison.
