Re: Hesitation @ lower rpm

Two probable causes, You do not have enough fuel pressure or the TPS functioning. Put a pressure gauge in the fuel line from the pump. The easiest spot is in front of the in-line filter. At a min you need 38-40 PSI. If it below the 38PSI get a new pump and strainer. Check out Rock Auto for a good pr...

Re: notnilc20's 1986 ae86 Hatch build/restoration

One suggestion on the setting up the TPS. The bottom screw attaching the TPS to the TB, can be a real PITA when it comes to access. $hit can the stock Toyota screws and go to your local hardware store, in my case Home Depot and get two Allen Socket screws. They should be 4mm - 0.7thds x 12mm lg. Lif...

Re: MR2 7 ribs block for ae86

The MR-2 block should swap right over into a GTS, assuming that you have the old RWD engine to change out the water pump, pulleys, manifolds, and flywheel, etc,etc. The only problem I've heard of is that some of the engine block bosses, i.e. engine mounts, where not tape out on the MR-2 blocks.

Re: Timing woes and tps'

With all those issues, it sounds more and more like your timing belt may have jumped a tooth. How old is the belt? I would remove the front cam belt covers and verify that the cams are set correctly. You probably need to adjust belt tension or replace the belt.

Re: Throttle stop dampener

Adjusting the throttle damper will not improve the idle. It only effects the throttle rate of closing. There is a rubber plug on the top of the throttle body.

A 1.5* caster increase will make the steering heavy. I would take a look at the front lower strut bar. You could probably modify the rubber attaching bushing.

Do the string alignment also check the panhard rod is not bent or the bushings are off center. There is a chance that if you swap the lower control arms left to right that it may correct the problem.

A possible Toyota option is the MA46 axle used on the light pickups and vans. But only the 2WD Van will have a 4 lug mounting while the others will be 5 or 6 wheel lugs.

I do not think you could justify the cost of a shim kit for one set of cams. You can typically get new shims from a Toyota dealer in just one or two days. If there is a problem in Germany, there are several motorcycles that use the same size shim. You will probably only need a couple new shims for e...
