i have a 4-tec. i have had so many probles with it. i ran one motor in a different car, and it was tuned in. but it will barly run when its in my 4-tec. all the berings are good, belts are a little loose, and it seems like its binding some where.

Remove center belt and check if all two transmissions are free of binding points, if not, cleanup all the bearings with some fluid (soak them in denatured alcohol for 1 hour, dry them and apply a little of a quality bearing oil (serpent is good). If any bearing feels gritty, discard it and change it for a new bearing.

If stills doesn't go fine, try swapping the belts of a brand new set and see if it helps. Check the pulleys and every other rotating part for binding points.

Some cars doesn't go as free as they should, probably your car is one of those.

He just needs to isolate the problem. Since he has already ruled out the engine, go on from there. Does the car roll freeley when pushed?

Is his problem that the motor doesn't seem to run well in the 4tec?

It would really help if he could be as specific as possible when he describes the problem.

Also, are the clutchbell or other items rubbing the chassis? Is he using the stock clutch/flywheel/gearing?

The new MTX-4 and the RRR both want you to run smaller front tires.

I think you guys over looked something! The 4-tech has a P.O.S. Pipe, I would bet it is restricting the flow.............

these guys obviously don't see the question lol. How are the wheel hexs held on on the 4tec? Some cars if you over tighten the wheels it will slide the hex up and lock it up. I would pull the motor if it still binds pull the middle belt off and find out where the bind is but check the wheels it might be something stupid like that
