you always could, but dont do it!

You would have to have ALL internals set up for higher RPMs, ie. replacing/resurfacing/re-forging all internals.

Wouldn't be worth the money in my opinion, unless money is no option and you have a car collection that rivals Jay Leno's...

I have a rather large amount of money available, I may give it a shot after all. I'm not into buying a car, fixing it, and then selling it quickly. I will hold onto this celica for years to come. I prolly wouldn't use forged internals though. Maybe hyperstetic pistons. I believe forged pistons will rock unless they are combined with forced induction.

how % of your driving time your planning to drive in the power band WOT?

Whenever I get on the highway. Regular driving, I'd like to shoot for 50%. Right now...maybe 20%. Why do you ask?

Whether it's justifiable or not.

It's going to cost thousands of dollars for you to get your internals remade, and balanced for higher RPMS.

Forget that then. I just want to wot it maybe up to 5500 rpm then but I don't want to have to worry about it too much. I ordered the mild set of webcams and they give the best performance at wot through the power band up to 6K from what I was told.

My main interest is if (with my block at 182K and it is in great condition) with the webcams install, can I wot it whenever I want to (as long as I don't redline it) without causing damage?

yes, WOT < redline + in operating temp. should be fine.

sounds nice going to the freeway huh.

Nics, thanks for all your help! Yeah, it sounds great on the freeway. I never (if you could believe this) floored my celica before recently and I've had it for almost 2 years. Once I floored it, it had a very nasty rumble sound at around 3200 rpm through 4500 rpm and it has a great pick up too. Now I can't seem to drive it regularly because it's too much fun!

yep, i love it uphill when rpm go at 5k and yeah great pick up and you always wanna stay there but sadly it hurts my fuel economy so thats why i do it before fuelling up.

Don't floor a cold engine - It's basic science, things shrink when they're cold and expand when they're hot, if your engine shrinks around the piston and piston rings then obviously there is increased wear as its a whole lot tighter (probably not far off from seizing and you notice how the engine feels heavy before it warms up), this in combination with oil not being at operating temperature will provide less lubrication, hence oil has 2 parts to the viscosity rating - one at cold one at operating temp.

The rev limiter - It's made up of many factors, For one theres no point revving past the redline with stock cams, Look at a dyno curve with stock cams and aftermarket cams and you'll see why -- it's like revving down, power is at the top of the curve, revving past the curve is essentially decelerating. Secondly in order to keep producing power in the high revs the engine needs to be high compression (the FE engine is not.) Third and most importantly since there is no point in revving past the redline (and especially with an FE engine) the engine internals are not designed to cope with the extra stress -- as mentioned balancing and all that crap, bore and stroke ratio, total amount of stroke, etc. These factors come into play well before any fueling issue should arise unless the fuel filter is clogged or something.


There is no reason why you can't floor your engine from 0 to the redline if you look after it, nomatter what it's age but hard driving on a cold engine is a sure fire way to f*ck it!

^^it has been discussed to run it on operating temps.

nice info on rev limiter and i agree you can floor your car. did it too a number of times, just not pass redline.

Good to know, thanks guys!
