Topic: Quick Question 22RE rev limits

[JohnHalladay]

Does and 80's toyotas come stock with a rev limiter?

[boggerunner]

fuel injected or carbed?

[JohnHalladay [OP]]

EFI

[boggerunner]

im not sure, ive seen a buddy down shift instead of up shif on the interstate and it hit 9 grand

[JohnHalladay [OP]]

hahaha  i bet that was sight to see and hear!  well does anyone else know??? 

[Pat]

yes efi Does, i think 5500 rpm..  But down shifting cannot be controlled by a rev limiter..  the revving is being done by the momentum of your rig and the gear you slam it in too..  but pushing the clutch in should do the trick

[jimbo74]

i dont even see how 9k is possible, thats outside the range of the stock tach... and even then, what did he slam it into first while doing 80 mph? just sounds liek a gross exaggeration

[boggerunner]

he has 35" mtr's and was runnin down the interstate in 3rd at 4500 and went for 4th, and grabbed a handful of second. and 5500?  that cant be true, ive had my 4runner up to 6500 all day long, so deffinantly not a 5500 rev limiter

[JohnHalladay [OP]]

this might be a question for marlin! haha

[joey0712]

Hold her pinned and see what happens. Its gonna go dadadadada or BOOM!!!!

[JohnHalladay [OP]]

ill let you test that on your truck! i got a brand new motor in mine! lol

[79coyotefrg]

a 22RE wont breathe (restriction in the intake and head) enough to rev past 6500 or maybe 7000, without cam changes and some porting
the 22R/RE is a long stroke engine and  really doesnt like anything over 6500,(bottom end)  meaning you really have to work  to get that rpm


unless your running a 20R head on a 22R with a big cam like i used to, i miss that motor

it died when i dropped the #4 exhaust valve at 7200 rpm, 

my tach goes yellow at 5000 and red at 6000

[JohnHalladay [OP]]

i do have a stage two cam in mine with punched .040 over

stage 2 from who??  it REALLY matters,  what lift and duration??

[Rocksurfer]

No rev limiter in a Toyota, just the limits of the engine to suck that much through the intake. Then of course the valves floating and creating a limiter-like feeling.

[JohnHalladay [OP]]

its an Engnbldr 261 cam

[79coyotefrg]

its an Engnbldr 261 cam

um what part of stage 2 is that??

lift??  duration??

[JohnHalladay [OP]]

Stock is 198°, .398" lift, 110° center

the 261 cam that i have is 218° & .425" lift, 110° center.

The 261C has more duration @ .050" lobe lift, 222°. It has less lift,
.410", and faster ramp speed, so it recovers quickly off idle and has more
RPM portential..Perhaps 3-4 H/P less at peak but longer powerband.

[79coyotefrg]

for example,  my LC Engineering Stage 2 race cam is .460 lift 290* duration and is designed for 1500-5500 rpm

20R/22R - Stage 2 Camshaft
4WD / Pre-Runner / Hot Street 2WD (1500-5500 rpm)
Modified Carb or Throttle Body & 1 1/2" Header

   Intake    Exhaust    
Valve Lash    .008    .012    
Valve Lift    460    460    
Advertised Duration    290°    290°    
Duration @ .050"    240°    240°    
Lobe Center    102°    118°    


Intake Opens    18° BTDC    
Intake Closes    42° ABDC    
Exhaust Opens    56° BBDC    
Exhaust Closes    4° ATDC    

[JohnHalladay [OP]]

as i said above mine has .425" lift and 218* duration

i wouldnt be concerned with over reving, unless you plan to sit at redlights with your foot on the floor for some reason

[JohnHalladay [OP]]

yea i dont really plan on doing that. i like my motor to much!

[79coyotefrg]

as i said above mine has .425" lift and 218* duration

i didnt see you post till after i posted

[JohnHalladay [OP]]

hahaha ok no worries lol i was going to say, can you read! hahaha just kiddin.

[79coyotefrg]

the 261 eb cam is close in specs to LCengineering's  base model cam,

20R/22R - Mild Street Performer Camshaft
2WD or 4WD Carb/EFI (1000-4000 rpm)
Smooth Idle, Stock Replacement

   Intake    Exhaust    
Valve Lash    .008    .012    
Valve Lift    424    424    
Advertised Duration    270°    270°    
Duration @ .050"    220°    220°    
Lobe Center    102°    110°

[79coyotefrg]

hahaha ok no worries lol i was going to say, can you read! hahaha just kiddin.

yep, just slow when im trying to keep up with 3 different threads and find info for 3 different people

i think its bedtime for me

[79coyotefrg]

btw  listen to my engine,  the big cam isnt for everybody, actually they say  this cam isnt compatible with efi without mods to the efi

[JohnHalladay [OP]]

that sounds like my motor. just not as bad of a valve tic. lol what muffler do you have?

[Rocksurfer]

i wouldnt be concerned with over reving, unless you plan to sit at redlights with your foot on the floor for some reason

You've got to be kidding, I over rev offroad in low gears.

[JohnHalladay [OP]]

see thats what i have done! but i dont have a tac so i dont know what im reving at!
