Well Sean (funkey_monkey) and stayed up tell 3:30 AM and was able to finally able to started it up!!!!!!!!!!!!! Wow this thing has some oil pressure. This 7m sounds mean!!!!! The gauge oil pressure wasent working so we pulled a cam cover to check every thing out and yep lots of fresh oil coming out. But just to make sure we pulled a oil cooler line on start up to double check, and it shot oil out of the hose like water coming out of a garden hose.!.!.!.

A couple questions, First dose anyone have 272 cams and a ffim? I ask because I have 0, thats right no vacuum pressure. Gauge is working, When we pull the line off of the intake manifold there in super little vac. Like 2-5 inHg.
Also we were able to build 5-6 lbs. of boost wile sitting in the garage just reving the engine!!!!!!! I have never seen any turbo car build boost while not driving!!!!!!!!!

Fuel pressure gauge is reading around 55 psi with this no vac. going on.

Dose this have to do with the 272 cams????? FFIM?????? Is the custom made 4" TB I got from tubbie some how fubared up????????

Also My gauge cluster is dead, the lights turn on but nothing else works, No tach, oil, boost, water temp. I just pulled the glove box and all body plugs anr together and tight. Also pulled gauge cluster and all harnesses are pluged in there also. What gives?

Any ideas what to try next. Also there is a massive oil leak on the from of the engine, looks like the from main seal behind the lower timing cover.:( looks like my engine builder is going to get a phone call :cry::cry::aigo::aigo:. Well over 5 g's for this rebuild, it better not drip a single drop of oil untell there is 70k miles on the engine.




Vid. of cams to double check oil


video of first start up.


And another trying to get it to idle.

seems like ignition timing might be way off, it happened to me last week when i started my rebuilt engine.It was 180 off and i had 0 vacuum.set the cps as per tsrm

It was off quite a bit during first start up. I just got it set to 10-12 degrees with the neighbor. I used the pic. from the forum here to set cps in the right spot. But never the less It could be be 180 off. did your engine start and some what idle when you were 180 off? Also I can just pull out "spin" the cps 180 right.

Also I did not/ or do not have any code that I know of. The ABS light is on But this shouldnt affect the idle. I do not remember if abs light was on when I first bought the car or not its been almost a year.

cold my engine would start and run extremely rich-or i gues it was burning the mixture...It would also choke when i gave it gas...it deffinatly idled much better than ur vid though...You need to make sure you set the crank tdc COMPRESSION stroke in order to set the timing correctly.

Cams WERE degreed in according to cam card. Since then I have set the gears back to "0" and I have around 6-8 inHg of vac now, not much better. CPS is set according to the pic floating around here on the fourm that sheaff posted and others(same pic).... I could 180 the cps but then everything "would be 180 off" from what every one else set theres at. The round part of the CPS is closest to the flat part of the frame on the CPS. This is not my first swap, I have swaped in and out more then 10 7mgte's in my life. Unless setting crank pully to "0"(TDC), cam gears lined up with there TDC mark, and the cps set to shaeff pic is WRONG, this will be news to me.

Sorry, I am a little crankey b/c this poopra is kicking my ass. The timing is not perfect yet timing light is showing it around 15 degrees or so. plus with this main seal leaking like like it is I dont want to run engine more then 1 min. without checking oil level.

Also with every gauge dead and all body plugs behind ecu, gauge cluser harnesses and fused checked I have no idea where anything is at except for my oil temp, boost and fuel pressure, pro sport gauges ;)

Any one have a JDM ECU I can buy of try out? no egr stuff, never had a problem before with not having it on, but again this is my first Cali. supra :(

yep, Sean and myself check but I am looking for some carb cleaner now to spray around every fitting to see if the idel jumps up.

Ok, development!!! I found some starting fluid (ether) Sprayed every vac. port and TB.............nothing happened. Sprayed some by the fuel injectors/lower intake manifold and it did rev. up not much but it did rev up. So I think there is a leak between the manifold and the head. I will "try" (bolts suck ass to get to with ffim) and tighten manifold some more.

There is no gas leaking anywhere. So I am guessing that the ether is not entering the engine via injector, orings/gaskets things, right? only the manifold?

well.... I checked the intake bolts and found a couple that were loose. (must have been the late night oil we were burning) But the vac. isnt any better still less then 10 inHg. I haven't tryed any more ether yet. Running out of oil. Jim better have an answer for this.

I have been trying to figure why none of my gauges work. Plus it's bed time for me my brain hurts!!!! It seems like there isnt any power. Any one know what wire is for powering the gauges? (not the lights)

Also I noticed when I jumpered E1 and TE1 to set timing the check engine light did not blink fast. I swaped bulbs with one from the door open (that I can see working) and still nothing. So it is not the bulb. Is this part of what I am guessing "not getting power to cluster"

http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=D&P=8

This is the best I can find but dont know everything. Looks like yellow wire on plug A, #10 on the back of the cluster? not sure thou what plug that is, if that is right at all.

Good night all i will check back tomarrow. Keep the ideas flowing. And thank you all again for the help. I couldn't do this with out you guys.

re-shim the valves after you installed the cams?

I had a faulty micrometer give me readings of my shims being too thin causing my valves to hang open at 0 lift and give me no compression (0 vac).

I did not personally do the work, Jim Hall did all my engine/ head work. I would hope he did eveything correct, but I am starting to second guess his work now :( no vac. and a major oil leak. He has also been MIA, several calls & emails with no responce. :icon_evil:icon_evil:icon_evil
