 22R - Bottom End (ConRod) Power & RPM Tolerance ???
|
Thu, 30 September 2004 13:28
|
 |
Anyone have any thoughts or statements on the following??
- strength of 22r rods
- design flaws and or failure points of 22r rods
- pics of a 22r rod
- achievable/sustainable RPM of stock 22r rods
- achievable HP on a stock 22r bottom end
anyone have a dead 22r sitting around i can yank the rods out of for a look ??
cheers

Does 22R have the same bottom end than 20R?
At least 20R has bad rod to stroke ratio (1.55). By eyeballing my Haynes manual I'd say that the 20R and 18R has the same rods. How about 22R, I dont know.

Ed, go to www.celicas.org, sign up to the OCC list and ask away, They're the 2xR experts; as a lot of OCCers have been there, done that, they should be able to tell you everything you need.

I'd have to go home and measure up my fucked 21R rod...
The 21R and 22R rods are the same deal.

How long is 22R rod? how about big end bore? Ed do you have any measurements for 7M rod?

bugger! i misread the dimensions 
different catalogues seem to vary between dimensions based on crank PIN diameters, and others on rod TUNNEL diameters 
22r is no longer what im after... but here are the specs anyway. feel free to add your own rod spec data to build up a small database 
----------------------
22r rod specs:
CC length: 5.819"
BE Pin Dia: 2.0857"
BE Tunnel Dia: 2.2047"
BE Rod Width:
BE Bearing Width: 0.866"
SE Pin Dia: 0.8656"
SE Tunnel Dia: 0.9449"
SE Bearing Width: 1.130"
SE Rod Width:
----------------------
7m rod specs:
CC length: 5.984"
BE Pin Dia: 2.0466"
BE Tunnel Dia: 2.1659"
BE Rod Width: 0.975"
BE Bearing width: 0.783"
SE Pin Dia: 0.8661"
SE Tunnel Dia: 0.9449"
SE Bearing Width: 0.994
SE Rod Width:
----------------------
2jz rod specs:
CC length: 5.590"
BE Pin Dia: 2.0465"
BE Tunnel Dia: 2.1663"

Ovlov connecting rods.
Engine type: B17, 19, 21, 23 (OHC)
75-85
240, 300 and 700
CC length: 145 mm
BE Pin Dia: 54 mm
SE Pin dia: 24 mm
B200, B230
85-88
200, 300, 700
CC length: 152 mm
BE Pin Dia: 49 mm
SE Pin dia: 23 mm
B200, B230 "K-block"
89-98
200, 300, 700, 900
CC length: 152 mm
BE Pin Dia.: 49 mm
SE Pin dia: 23 mm
All above are inclined engines (opposed to perpendicular engines). Connecting rod material changed from -80-> to more robust. Connecting rod are the same in NA and turbo engines. Vulva connecting rods are noted as a strong connecting rods.

"good" factory design being the very point...
ahhh glen, if only you could appreciate the beauty of what it is to build a 'proper' NA motor

I decieded to leave the N/A's for the little girls.
Im 'building' a real motor. 
Good luck with your rod search, but 2jz rods will be fine for me

and why are the 2jz rods 'fine for you' ?
what is it about the 2jz rod that suits your 'build' so 'nicely'

Ed, I assume that you're improving your rod to stroke ratio. May I ask what is the ratio that you're targeting?

now here's a man who knows what hes talking about 
aiming for 1:1.73 (stock 2jz is 1:1.64)
thats the tallest i can get with stock deck height and 'reasonable' pistons - ie compression height around 29mm.
the intake will be a high velocity type, and obviously some well calculated cam timing to suit - which im yet to fully get my head around. ill be talking to a few cam people about that - theres simply no way i can figure it out myself
looking at redline around 8500

glen - common dude - theres a shitload more to rod choice than just that
sure stock rods 'will do', no debating it, but its another ballpark to start looking at how you want the engine to behave, what intake youre going to run, how you want the cyls to fill, and what kind of power you want, where in the rpm band.
dont diss a guy for optimising an assembly - its hardly goping to fault the design

So you need 157.5mm long conrods...
Im considering 1:1.81 which means 16deg rod angle. Pretty ideal I say. I havent yet sort out the skirt clearance. Compression height is no problem for me.

jayem - this is for a 2jz, not a 7m, so the rods dont need to be quite THAT long 
more around the 148/149mm mark
id like to reach 16deg, but im going to have to settle for 16.5deg - simply not physically possible
whats the rest of the engine designed like around that 1.8??
cheers
