how much fun did you have porting? this is how i felt after mine rolleyes.gif with my build, all i did to the head was port and radius cut the valves and a 30 degree backcut. Pretty sure it made a hell of a difference. Head work is %60 of your power. nice work.


The porting was really fun to do. You can see literally see and feel the difference. The head work is now done. Going to bring it to the rebuild shop today to do a leak test. When that's okay i'll be mounting the head on the block this evening or tomorrow and then i'll be able to mount the cams, cam bridge, bearings etc.

We've also get all the paint of the cam cover and today it'll be painted in black again. It's getting better and better, i can't wait to have this engine in!

This is the assembled head:

Yes i'm happy!! Today the engine head was vaccuum leak tested and it was perfect! Not bad for my first valve grinding job smile.gif Have to note that the valves weren;t that bad though wink.gif But still i'm very pleased with it. Now i can continue working on the engine!

So updates will be there soon!:)

Updating time!

Yesterday i've managed to mount the oil filter bracket and the oil filter first. After that ive mounted a new headgasket and reinstalled the cams. I was a bit afraid of installing them because they were up a little on the end. Asked about this at the rebuild shop but they say it is absolutely normal. There's no point where the cams don't touch the valve lifters. Just ensure that the crankcase pulley is at TDC and the dots on the cams are alligned properly. To be 100% sure it was advisable to turn the crankcase about 25-30 degrees counterclockwise. Then all the pistons would be halfway, so hitting the pistons with the valves would be impossible. So we've mounted them in multiple passes and very secure. So not thighten them to hard right away.
Also i've installed the water outlet and inlet and some small things. I wanted to mount a new thermostat but the new one differs a lot from the old one. Have to ask if that won't be a problem.
Hopefully tomorrow i'm going to check the valve clearance, put the new hydraulic tensioner on and install the cam cover.

Anyways, here are some pictures:

New headgasket on the block:


Marked the headbolts to ensure toquing @ the good patern:


Used some hulp for the toquing to turn them 90 degress twice wink.gif:


Notice the white mark on the head bolts. I did this to ensure i would turn them exactly 180 degrees in total:


Mounted cams:

Time for another update:

Have been busy a lot with with installing the valves en valve stem steals. How stupid could i be, trying to put the seals completely to the bottom of the valve guide :S. Should have read better before. Killed 6 of them and i have to remove the rest of the valves to check the other seals. When comparing how easily the valves could go in and out, i spotted a little rip/tear in one of the seals. When checking 2 other seals i spotted the same problem frown.gif. This is really expensive teaching money, but learned a lot.
Wow and how difficult the valve retainer locks wil go in position. This took my a LOT of time. And worst is that because of the seals i can do it all over again frown.gif

Good news? Yes, i picked the stock airbox and exhaust header up from the powder coating. They really look as new, or maybe even better then new biggrin.gif I'm really happy with that and it's worth every penny!

Because i had to wait on the new valve seals i went ahead with the throttle body. I removed the injectors and changed them for some i had ultrasonic cleaned before. Changed the o-rings and vibration insulators for new one's and (pre-)mounted the brackets.

Here are the pictures:

Powder coated airbox:

So has been a long time since the last updates but the engine is in for a week or 2 now!

I had to grab the power steering lines from a 4EFE Corolla and also took the reservoir of it. I used a part from the OEM power steering line from the Blacktop (it was ofcourse cut! frown.gif) and let a hydraulic company press it together with the Corolla power steering line. Its a great fit, you can see in the pictures below.

For the throttle cable i grabbed a cable from a 93-er Celica 5SFE from Rockauto. It's a bit long but besides that it's a nice fit. We've made an adapter plate for the throttle bracket so it cannot move.

For the igniter we've also made an adapter plate so that's also a nice fit. Going to paint it black later this week, so that it's completely finished! biggrin.gif

At the first startup we had 4 codes or so. IAT (not connected), MAP, TPS and some code i don't remember. After three double check the vacuum lines and connecting the IAT all the codes were gone except for the TPS code, 41.

And that one wouldnít go away. Iíve bought a new tps, asjusted it with Blacktop manual, but still the code. It made me go crazy. Then iíve decided to meausure the voltage at the ECU of the VTA and E2 connectors. They voltages should be around 0.3V @ idle and about 4.7V @ WOT. Iíve meausured 4.7 @ idle and 0.00V @ WOT. Hey thatís strange i thougt, look like itís upside down or so. Double checked the manual if i mounted the sensor upside down, but i didnít.
So later that evening i had a sudden inspiration. I remembered using the TPS connector from the 7AFE while that one is exactly the same. So i thought: are those pins located at the same position as the one of the 4AGE TPS??? So i went to bed and first thing in the morning was grabbing the manual and walk to the car. And YES!!!! found the problem! Theyíre located in the opposite way. So iíve repinned the connector and gone is the code biggrin.gif

The engine runs a lot smoother now! Still running too rich, cause i can smell the fuel and hear some little backfires now and then. Also the starts are a bit difficult now and then. It seems to run on 3 cylinders for a second and then it runs fine.
Have to sort out whatís causing this. Maybe the O2 sensor had a hard time after the first starts with all the oil and residues of the painted parts wink.gif Have to check this out later on.

Also the valves are ticking a bit. But they were about 0.01-0.02 mm out of specÖmeaning too loose. Iíve didnít buy new shims while mostly the valves are tighten up after a few thousand km. So hopefully thatíll go away or otherwise i have to re-adjust them.

So the pictures:

New harness made by myself biggrin.gif:

Thanks man!

Still have to figure while it's running so damn rich. Maybe i should wait till the break in period is over. Today i've changed the injectors for other onces without much succes. The first time i changed them it runned only on 3 cylinders. So i grabbed another set that was lying around resting and the car runs back on 4 cylinders again. But still i miss power. Still seems that it runs way to rich, giving me some little backfire in the airbox...i must admit does sound nice, but shouldn't do it.

But i'm also proud, very proud i must say while today i've done compression tests...all cylinders reach 190 PSI! That's spec biggrin.gif Not bad for a first time wink.gif

Cylinder 1:


Cylinder 2:


Cylinder 3:


Cylinder 4:

Backfire through the air box usually has to do with timing. Check the plug wires first then check the mechanical timing and make sure you're not a tooth or two off on the timing belt.

Thanks, I also thought the rusty background would be nice smile.gif

I hear at the end of the week what it's worth....

I had a pretty decent appraisal, don't know if it handy to put the value on the internet, but i'm happy with it.

The car has almost done 1500 miles since the rebuild and used somehwere between 0.2 and 0.3 litres of the break-in oil, which is really nothing really.

The valves clearances are all in spec now...did have too wait 2 weeks for the shims to get in and the valve train noise is a lot less. Still hear it, but that is either because of the break-in oil or the VVT cam. So that's something to replace in the near future biggrin.gif

Did rev it some harder already but not past the 6800 redline (of my stock 7AFE rpm gauge wink.gif) and it goes pretty well. I do need another gearbox though, cause my c52 has really really long 2nd and 3th gears. I think i can rev to about 120 km/h (GPS speed, not tacho speed) in second gear. In third it should get near the 180 km/h i guess.

I think i'm going to buy a C160 gearbox, cause they're easier to get here in holland. Don't know if they'll easily fit, but that's something to find out soon smile.gif

For the interested people, i've just shot a movie of 8200 rpm Celica ST wink.gif. Don't mind the quality, cause my phone camera was damaged during the rebuild and need a rebuild too smile.gif I think the sound will make it up for this haha

My next project will be a 6 speed gearbox, while the gears are really really long as you can see on the video. @8200 rpm i'm driving 120 on gps in second gear.

It's still running a bit rich and i think i miss about 20-30 hp, but i hope after a while it'll get better. I need to drive it faster and take it (a lot) higher in the rpm range then during the break-in period. Endly that break-in period is over and now it's really happy with 5W30 full synthetic smile.gif

The sound is really awesome, that's going to cost me fuel haha! From 6000 RPM it's like having a little extra turbo or so, cause then it really goes!

Yesterday went to Germany to test if the speed limiter is working and unfortunately it does. It's pretty harsh i must say. Likes like i'm running into a wall when the speed limit is reached. And that's about 192 km/h on GPS.

But here comes the movie! The speed on the tacho it's the real GPS speed, this is caused by my 17" (way too heavy) rims. Hope you enjoy the sound! tongue.gif

Thanks i will! biggrin.gif

Yesterday i've been busy for about 3-4 hours to clean the gearbox. What a mess it had on the outside. From the inside only a layer of dust, so that's a good sign biggrin.gif But it looks a lot better now already:
