i'd say lets run a GB for rods and piston kit....
i want a ruff compression of 11:1 or so cause i wanna keep NA
with the proper fuel upgrades this is
and as for RODS what would be options and such?
i'm not familiar with rods and specs

ok i got off the phone were looking $450 piston kit rings etc any ratio rods $650 made of steel so tell me what you guys are thinking.

Back in the day I was in contact with Ray Hall who built the 20valve 1.8 7age turbo. He had a custom rod made and I have over the years been in contact with this company. I am pretty confident that I would be able to set up something in the price range that would be less than 600 per set of rods. Depending on how many people I would think something like 575 or so maybe less. If I where doing something cost effective then Gze Pistons with stock 7afe size rods (but aftermarket) should go for about 800 or so for everything. This way everything will bolt in with no modifcation. If you guys are serious I could look into it further.

yes, we are serious on this, i was looking for somthing that is not too pricey over the year now..... and only thing that i found was crower and pauter, and both they charge 715$ per set + shipping......

So if you can get 575$ for the set, i would be in for sure.........

I've been looking everywhere for those specs... I don't have them in my database...
As for fitment... gotta do live measurements... compared to the block. The 7A has a larger stroke than the 2ZZ also... so this might not be so good...

"then the machine time to get everything to work plus all that math for volume and cc displacment"

i really dont' see the machine time with fallen's idea of the b16 rods

minus the fact you'd need a 21mm wrist pin
so you'd have to machine each 7afe piston 1mm? or whatever piston you chose?

the only machine work i see is the wrist pin at this point the rest should all bolt up

ok, bringing this one back from the dead in order to discuss rod options.

Ok, in regards to 2zz rods: They are Basically two millimeters too long. However, in my reading, the crank journal diameter is two millimeters too small. If you were to machine the rods to be one millimeter shorter when attaching them to the 7a crank, that would make the fitment fairly close with the 4age head. If you were to use new 18mm pin diameter 4agze 8:1 compression pistons (machined in a way to a decrease the length by one more millimeter) which would have to be cut to the 20mm pin size of the 2zz rods... you have quite the combo, and rods that can live with 270whp boosted no problems. All that machine work has a cost though, so here I will discuss another option I came accross.

A LONG time ago I discusses using a set of B-series honda forged pistons. Why? they are hella cheaper than forged pistons made for a toyota. The problem is, they have a pin diameter of 21mm compared the the 20mm of the 7a rod. What about B-series rods?

Amazingly, I have found that the B16 rods are near to identicle on the spec sheet in comparison to 7afe rods. So, let me lay the specs down

RODS \\\\Length\\\\piston pin\\\\\Crank journal diameter
B16\\\\\\\\5.290\\\\\21mm\\\\\\\\48mm
7afe\\\\\\\\5.2165\\\\20mm\\\\\\\\48mm

Honestly guys, that's bleeding close. With the 4age head and forged 4age low comp pistons, we are looking at virtually no size difference between the 7a and B16 rods. With that in mind, I leave you this link

Those are eagle H-beam rods that can handle more boost than you would want to throw at them.

Opinions?

Amazing find Fallen >> I hate to say...... but ....... B16 pistons are the same bore as 7A pistons...... >>

And there are lots of versions availible on them... low CR, High CR. And i DO think - using them with the B16 Rods - the Celica 7A rods/piston problem would be solved.

answer one question guys whats the BIG END HOUSING SIZE on a b16 rod

if this is off and your using the 7a crank it will either push your piston into your head or not far enough the cumbustion

im not trying to rain on you guys i just dont want you to waste money on something that might not work but we wont know until we get more info or some trys it so if someone has money to throw at this go for it hopefully it works out if not just sell your rods or pistons

does anyone know the 7afe BE specs?

i already found the honda b16 specs as posted above ^^^
but if the 7afe is the same :/ we should be good to go with b16 rods and pistons?
