ok did a compression test just to get an idea of the engines health.

milage. 79,000
vac reads. 15-16in.
front rotor. low 100's
rear rotor. low 90's

what do you think , should i put my single on it or get a reman/rebuild first?

 

drive it hard. i bet it wont pop.

 

Hm. What kind of boost are you planning on running with the single, and what kind of power levels? Main downside I see to going with the single on that motor: you crack one of the used, high mileage apex seals and take out your nice new turbine......

 

its a small single apexi rx6b , plan on running 12-13 psi for a while.

 

I say go ahead and install it, that is not really any more stress than the stock twins are capable of.

 

should i do any kind of treatment? de-carbon or mmo in the oil? i premix everytime with mmo and 10gal of fuel right now and change my oil every 1k-1.5k miles. also the last time i changed my oil , when i pulled off the cap it had a greenish residue on there and down the filler neck????

 

Cleaning the motor with a little ATF never hurts

 

i heard some people use water.... anyway how much ATF do you use?

 

anyone have anymore imput on all this ??

 

why use MMO?

I suggest valvoline 2 stroke tcw3 ashless for premixing and I use about 6 ounces for every 10 gallons along with my omp.

im not too sure on the decarb methods ive never done it since im on a new engine. bucket of water and a vacuum line to the uim sounds good though while revin the engine

for the oil you could dump a bunch in there and turn the engine manually and let it sit over night and do it again and then turn the engine again etc...

 

I use about 16oz of H20 every 3-4 months or about 2k. I attach a vacuum hose to the throttle body and rev up the engine to about 3-4k.

Note: This will clean out the carbon but it will generate alot of heat in the exhaust. The last time I did it the downpipe was glowing. The engine does run noticably smoother after a cleaning.

 

i am definatly going to start doing the water treatment, just have to wait until its above 32 deg. here. i have been reading up on it and it seems to be a great treatment.

 

How exactly do you hook the vac hose up to the TB? Seems that a nipple on the UIM would be safer, no?
