OWNERS and BUILDERS • Re: Saving a crusty 16v 4age
Grant wrote:When you reassembled cam gears and timing belt, did you just set the adjustable gears to 0 until you get the engine running to do a finer tune? I have some Toda cam gears, and I'm wondering how to set them for the initial start up...Also, what did you paint those cam covers with? […]
TECH: Corolla AE86 • Re: Rear steer
Unequal length trailing links cause the pinion angle to change when the axle moves up or down. This does not occur if the links are equal length. The problem with four links is that when one end of the axle moves up or down when the car hits a bump, or is cornering and one […]
TECH: Corolla AE86 • Re: Rear steer
I think that just a small amount could be used to advantage, l'm guessing here but 2° (1° in/ 1° out) would probably be enough to make a difference.I couldn't really get my head around how the short links affect what is going on, they can't physically change the arc that the links run through.lt […]
TECH: Corolla AE86 • Re: Rear steer
Rear steer aka Roll steer, and interesting enough to force me to consult Google, from where I gleaned this information... Cars with rear live axles, also known as solid axles, tend to not have true bump steer. Since both wheels are connected to a single, rigid member they are incapable of having any toe angles […]
TECH: Corolla AE86 • Re: Rear steer
If you Google short track rear suspension systems, you see multi hole locations on both the chassis and axle for trailing arm adjustments. This aids wheel alignment for better turn-in, plus anti-squat for improved traction. Changing ride height effect both front and rear suspension, plus weight transfer.Statistics: Posted by davew7 — Wed Aug 07, 2024 […]

TECH: Corolla AE86 • Rear steer
No, not going mad!It occured to me that the rear axle has an element of rear steer due to link arm angles.lf the bottom link arms point down to the axle at ride height as the car corners and weight is transfered the out side rear spring compresses (the inside elongates) when the spring compresses […]

TECH: 4A-GE ENGINE • 4AGE Silvertop 20v MAF Meter adjustment
Good morning 4AG Family. Question, My current MAF Meter is working fine, but someone tried to move the screw to adjust the idling and I believe he messed the Air to Fuel ration calibration. Know he said he doesn’t remember if the screw was all the way down or halfway. He cannot remember how many […]

TECH: 4A-GE ENGINE • Re: Valve spring seats
Fair point about spring rotation.l think the best way to approach this is to replace the valve springs with some that will allow 10.5mm lift and will fit with the original bottom retainer.lncidently Catcams suggest the removal of the bottom spring retainer for their springs.Any ideas for springs to the above spec?ThanksStatistics: Posted by totta […]
