Well bad news for me. The motor has a knock and doing a compression test it was at most 125 and lowest was 110. Persistent knock between 1500-3k that was load and upwards not as loud but its there. 

 

The new black bov spring did indeed help with compression surge and the msd works. The tach adapter was screwing me up. Turns out for me i didnt need it but in general toyotas need it.

Lol it wasnt a good sign but ignorance is bliss and I didnt wanna believe it. I knew early on the motor didnt seem right. It was hard to pin it on a bad motor with so much of the motor having issues.

 

Plans are this week start pulling stuff off and have the motor pulled for the weekend. I also plan to talk with the builder and see if he'll refund the money since he just closed his shop. I feel like I can rebuild the motor but I know its a tough task and I want the motor done asap to still enjoy it for the summer, so may take it to a professional. 

 

Curious what the oil will look like once I drain it. All im hoping for is shot bearings and salvageable crank and block. Also hope to not take it to a machine shop because that will eat up weeks.

Well small update so machine shop was able to get the short block back together in a week which was awesome. Then Today just redecked the head because found a gouge in the head which leads me to believe in the future this motor would have blown if the bearings didnt go when they did. 

 

Also found out they didnt put a stock twin turbo head gasket in which is a 1.3mm gasket instead they put a cometic 1.8mm gasket which I didnt ask for. So with the thinner gasket it should run better off boost.

 

While it was at the machine shop added some ARP rod bolts and main studs since it was all apart again. Worth the extra $200 for peace of mind.

 

Other than that, once my friend is off we could put the motor back together in a day. So hoping to have it up and running by end of may early june.

 

Soliz good luck, its all about just having a good headgasket, arp head studs, rod bolts and mains if you want. Its a solid motor, I just had some bad luck. The oil was bad lots of shavings. But going to run 10w40 and for break in going to use a upgraded filter that will get all the little stuff in the motor.

So me and my buddy finally finished the motor. Took way longer than expected because of all the hurdles. Found 9 out of 24 valves to be out of spec, with 2 being double the specs. So those valves were either stuck open or closed. Crazy how the car even ran or idled the way it did, props to the tuner. But now to spend a couple days to put the little stuff back together plus have to torque the crank pulley which will be a challenge.

 

Also for anyone interested to know. I have a Holset HE351CW those come T3. Most manifolds now and days come T4. I had to use a spacer to fit on the manifold which made it 8 bolts to worry about. Well, I decided I wanted to take that out and cut the T3 flange and add a T4 flange. Sent it to my machine shop and the welder did a really nice job. I did all the measurements to keep my exhaust and intake the same without modding them for a lower angle. Im really happy with it and I hope it lasts. SO many people were telling me it couldnt be done, so hopefully I can shove this in there face. I only spent $180 to mod it and got the turbo for like $400, so all in way cheaper than a brand new turbo. 

 

Ill update once I get the motor in hopefully within this week  or weekend.

Finally got the car running! Turns out my distributor wasnt sync'd in so it wasnt starting. Quick look in the manual showed me how to do that, another thing the GTE doesnt have to worry about. She turned over and did the 40min break in. My friend suggested a 2hr idle break in and in the process, 30min in the fuel pump gave out :/ So ordered another Bosch 044, this time with a check valve and a shut off valve for the fuel cell. Since I didnt think that part through and fuel will go everywhere when I swap out the pump and check the filers lol.

 

I had the pump sitting for years in the box, so im sure it didnt help to just start using.I knew it was going out when my fuel pressure started creeping lower and lower. Had power but tap with a hammer and it kicks on. Oh well atleast the motor runs enough to do a break in! Going to aim for 500ish miles before going for a real tune and hopefully get 400hp-500hp. It made 398 at 7psi on 9 screwed up valves and a knock lol.

Installed the pump on the first of July. Drove it around 100 miles then another bump on the road, injector drive for cylinder 1 took a dump. Had spark but injector wasnt coming on and could swap it around and the injector works but the wiring seemed to be the issue. Tested it seemed good but no power from ecu. Not the first time a driver went. Spare drivers apparently are no good. Luckily someone on ebay rebuilds them, so sending it out tomorrow.

 

Driving it off boost its fast as hell! The welded R200 for sure wont handle it lol(I have an LSD that needs to be put together), sounds like itll blow. Car needs new tires anyway so ill let them spin. Kind of want a new fuel cell thats baffled the foam stuff will eventually clog the filter again anyways. Also the fuel gauge drives me NUTS! how can I be on E and fill up with 6 gallons on a 17 gallon tank! Looking at a classic instruments fuel link interface that has a resistor in it to really level out the fuel gauge.
