warm engine compression results were (dry test)163-165-165-166So if this air coming out my valve cover is the valve seals would this be enough to cause slow spool?Also when I spin the turbo it spins very very freely almost too freely, could this be a sign of blown or fried turbo...

if the compression test comes back "good" would it be the valve seals and if so can they be change on the car or do I have to pull the head?Would leaking piston rings cause slow spool?also the other symptom I am having is very poor gas mileage.Can a turbo have zero shaft play and no...

I swapped out my turbine housing with a known good one, I saw a very slight increase in max boost and spool was ever so slightly better, but it still spools too slow, I did another boost leak test and I have a good bit of air coming out the valve cover vent(it feels like the amount of air...

I replaced the gasket between the turbo and exhaust manifold and it still is slow to boost. I did another sea foam test and get smoke out the turbine housing flapper arm to the internal wastegate and out the vertical line that looks like it was made in the casting I guess it is cracked hairline...

I ordered one of these for all three of my mitsubishi turbo cars thanks, but I did another BLT and plugged the PVC line to eliminate this from my BLT air still is flowing out the oil fill hole could this be because I did the BLT test with the engine cold? I also found a boost leak at the EGR...

I disabled the wastegate by plugging the line to the wastegate acuator to allow "full boost potential".... also how do I put boost and wide band data in my log? Also when doing the BLT I can not build more than 22psi and I have my air compressor set to 30psi... where should I have the enigne...

I have 2g gst.I am getting some pretty bad turbo lag. The freshly rebuilt EvoII Big 16g is spooling maybe 10psi at 3500 rpm and doesnt hit full boost till 6000 rpm. And this is with the wastegate disabled, I should be getting at least 30+psi in this situation.mods:-low milage jdm...

What are the gear ratios for 1st through 5th?I am trying to figure out what top speed would be at 7000rpm in 5th gearI have this MMZL trans in my 91 talon awd

Yes it is set up blow through. I will try setting it to 3.5 inch. The MAFT does not have output settings or 1st or 2nd gen, you just use a different chart when selecting the injector size. I was talkine with some on full throttle but didn't get any where. thanks for your help I appreciate it.

I am having the similar problem with my car except I have larger injectors 750cc and need help with this issue as well... I am wondering if you found the route of this problem. I have no clue where to start or what to check first.

LIFTER KNOCK SOLVED thanks to oil Mod. NUMBER 1!!! no 3G LIFTERS...just the one with the pin holes sorry no "after pics"...looked like the one posted at the beginning of the thread. We'll see how long this lasts only 10 miles one the newly built head...:rocks:

thanks so much :thumb: Now it all makes much more cents... (words=bad, pictures=good)!!:rocks:

can you please post a picture or diagram of exactly how you have this hooked up? I am confused and trying to understand more clearly as to how this is different/better than the stock setup...please advise:thumb:I was under the impression that a dual catch-can setup was the best(expecially...

once that box begins to fill with oil it will just be sucked through anyway as if it was not even there in the first place... the oulet should be on the top not the bottom... unless that is how you have it...i cant tell from the pics...but yeah that should work out as long as the barb on the...

just got the head back from the machine shop... they did not do either mod as I suggested to them(they said it was all "in spec"...) so I will be doing MOD #1... I will post if this eliminates lifter knock while still using stock lifters (not 3g lifters)before mod#1

no studs, just new bolts. the reason I asked was I thought he was saying to do this mod #2 if you are using the 7 bolt block with a 6 bolt head cause the 7 bolt bolck has bigger diameter head bolts.

even If I am using the 6 bolt head with the 6 bolt block?

(Oil Mod #2) <------------ do you think I should do this mod if I am using 6 bolt motor with the 6 bolt head? Or just do the oil MOD #1 since the head bolt size issue others have when using the 7 bolt head is not my issue... I just have lifter tick and the machine shop has the head. Also if...

-properly adjusted the base idle set screw (BISS) -properly adjusted the throttle cable -also cleaned the Idle Position Switch (IPS) <-------------- a poor connection in side the switch I beleive to be the culprit for not entering closed loop -also added a ground from the chassis to the...

what do you mean by compressor cover? Also the reason I was wondering about the fuel pressure was that I am getting very low readings on my o2 sensor at idle via the palm IIIc logger 0.0v- 0.1v. The sensor is new.Also I did have the boost gauge and all that Hooked up I just swapped engines...

yes I have a boost gauge just not hooked up yet...(I just got the car running and driving last weekend and only have a few hours each weekend to mess with it). I also do have a adjustable fuel pressure regulator installed...I pulled the vac. line off and set it to 38psi, just not sure if I...

I am running a 255llph wally, 6an fuel line, stock fuel rail, 750cc deka injectors, gm mas, MAFT, punishment racing shortroute FMIC, evo o2 hosing, 2.5 exhaust no cat/no emisson control, and a evo III big 16G.I have the boost line running off the intake manifold teed to the wastgate and...

I swapped out the o2 sensor with another used one I had laying around probably bad too:confused:. Then richened up the fuel by selecting the smaller injector size of 560cc (I am running 750cc injectors). Then turned up the fuel on the idle via the MAFT as far as it would go and the voltage...

I have a 1g Talon TSi AWD and just got it running and hooked up the data logger and noticed that the o2 sensor just stays at 0 volts and all the fuel trims(L/M/H) are all 100% at idle and driving. Does this mean the o2 sensor is bad? I have no CEL though.?

I have the same problem with the punishment racing FMIC short route kit... I was told that it will still be just as effective as is. Think of it kinda like your radiator, it doesn't have to all be exposed to function. It is more about the surface area of the intercooler. So I am not going to...

I think it could be the wrong pulley... I just bought a timing belt kit with all pullies and I believe the tensioner pulley to sit 2mm closer to the bracket than the original pulley, so it rubbed in some spots I sanded some off the bracked and the back of the pulley. Now it doesn't rub but I...

I just bought another 91 talon awd for the transmission. It turns out this tranny was no goodl, so I bought another 1g 23 spline tranny to install. The 91 talon awd had a 2g transmission installed in it when i bought it, and i would like to put a 1g transmission back into it. My problem is I...
