Have you ported your wastegate?

Why after 20+ years has nobody offered an upgraded turbine wheels to match the compressor??? The 57 trims already sell like mad. The turbine is the only thing that seems to be holding us supra/mr2/celica guys from making more power. Theres also the ct20B....hmm.

Just recently someone asked the same thing. With a lower temp thermostat they actually saw no drop in coolant temp. Better off spending that money and time to drain coolant on an aftermarket rad.

hey! do you still have my number? We should meet up and get this thing running. I had Integrity do the block and midway do the crank. Integrity was a little pricey and he works slow as hell but he does damn good work. Midway "hot rod'ed" my crank even after i told him not too. Guess i...

Im installing my wabro tomorrow. I have my j-tube drilled out and i dont plan on doing the 12v mod

Stock fuel system/ turbo at 7psi i can hear pinging up steep hills with 89. I think i should be able to do 10psi with 91 and stock cooling systems. More than that i plan on using 95 from the local track (laguna seca) until i get methanol injection.

Your story is just as sweet as the car. To me my supras just the money pit lol. Any more plans for the car?

If you could make a video of that exhaust you would be doing me a huge favor. I want to buy that system but i cant find any sound clips : (

Thats why i only lube my cylinder walls with WD-40. Make sure you use 5w-30 and not the monograde crap. You also want to roll the throttle and not just romp on it. I did my first oil change at 500 and the second after 1500. Changing the oil to much is a bad thing. It loads the engine with all...

Lorddigital, I have tien super street coilovers. Would it be worth it to get them revalved? They have 16/9 springs now but its to stiff and it bounces around on slight bumps. Im thinking softer spring and a bigger swaybar. I mostly do mountian driving and autocross. My specs are in third post.

I wonder when im gonna make out to the cencalsupras meet. Something always breaks once i think its ready. Oh and check out camberwear.net ive gone to a couple meets. No rice thank god.

Just because its not tested does NOT mean it doesnt matter. Why do you care so much about a goverment standard test when it has no use in real world every day driving? Where is your data? I guess you should tune your car stationary then too right ? :nono:

Put the car on the dyno and do a IM240. Then unplug that egr and see what happens to those NOx emmisions.

Biggest improvement for me was getting rid of all the slop. New rack non-pps Ball joints Energy suspension bushings Tie rods As of now my alignment is Camber F -1.6 R -1 caster 7.1 Total Toe F .01 R .30 0-50 mph it feels great but higher speeds it feels numb and heavy. Right...

I have the same issue but i only get it in closed loop. My motor is identical minus the bolt ons and it sounds exactly the same. Thing i will be checking.. Cps wiring Igt & igf Actual Coil ouput per cylinder Grounds Valve lash Vaccum leaks ( its possible for only once cylinder to have it)...

Yep take a look at the first bearing.

Question 2.. Efficiency. Think of an automatic transmission. At a given load low pressure would make it slip, high pressure would waste energy because of the unnecessary output of the pump(more load). The correct pressure will maximize efficiency ( not waste energy) by not letting it slip...

High HC Rich Misfire ignition timing Low compression High CO Rich Intake restriction Things like boost leaks, leaky injectors, high fuel pressure, faulty ignition system and feedback control is what you need to look at.
