plasma cutter, then a grinder to smooth it out. If all you have is a grinder.... Hold your hand steady, and get ready to take a bit of time doing it. There is no easy way without proper tools... 

 

You could always make a little card cutout of what you need done, and take it into a shop and have them cut it...  would be easier, but a few bucks out of pocket.

I have rough cut it, but i didn't take a picture of it. I used grinder with smoothing blade ( or what is it called ). But i think it's too small for larger curves :/ Belt grinder would be handy, but i don't own any

Haha, more pics comming tomorrow. But hey guys, did i do something wrong? When i assembled the new piston rings and i managed to get the piston to its hole with a pistonring special tool, i find it very hard to do a full circle with new piston rings installed (with hands). (compared when there was old piston rings it moved better). And yes, i added lubrication there. But i guess it just need more time and lubrication?

Alright guys, picture time :)

 

20130630_212729_by_atomicsickness-d6bdqb

It was finally time for installing these piston rings!

20130630_212709_by_atomicsickness-d6bdqh

After some heavy lubricating and a helpful use of piston ring compressor, i managed to survive of this hazardous operation, cheers!

20130630_211310_by_atomicsickness-d6bdrg

Btw, i'm sorry for using too much flash.. But here you go, just look at that, ah, so clean, washed and ARP bolts there tightened and keeping this together!

20130630_211323_by_atomicsickness-d6bdra

Just look at this, yum! So sweet, all 4 in and ready to roll! Yea and they all have that power coating on them, so that's why there is that white colour.

20130630_211334_by_atomicsickness-d6bdr4

And it was totally worth it, now all bearings are perfectly pushed to their desired places in a perfect lane!. Btw, don't seriously do it on your own, going to be horrible...

20130630_211930_by_atomicsickness-d6bdqz

And here is just a quick look up what's it going to be like (like you haven't seen a motor before). And i might add a picture what was the motor before this20130630_212020_by_atomicsickness-d6bdqt

Looks like a motor, ye? Oh and the power washer was so devastating so it rip off all of my bad painting spots so i need to re-paint them... But nothing big :)

20130630_212034_by_atomicsickness-d6bdqn

Damn that Nissan logo just looks awesome, don't u agree? no? well hmph..

 

ratsun_by_atomicsickness-d5lx2rw.jpg

Here's a photo just to convince you guys that i have made some progress, haha.

 

 

So... I might get engine assembled by next weekend and i need order some new parts again! (megasquirt etc...). And we'll see how it turns out with that intake mess we need to figure out!

Found something interesting http://www.ebay.com/...S-/380656126101

And yeah, i guess that i'm officially hooked to power! We'll see how much we can get out of this engine, haha.

Yup, now ordered some nice ARP  head stud kit for my engine, they can hold up 200 psi or 13 bar pressure, where can i know my engines normal pressure measurement?

Sup, this thread is me talking to myself, but it's okay, haha..

 

More pics, if someone is interested~

 

20130703_192831_by_atomicsickness-d6bt64

Some glass ball blasting again, half way done.

20130703_193809_by_atomicsickness-d6bt6a

Polished up...

20130703_194240_by_atomicsickness-d6bt6f

And the finished product, tadaa!... I'm considering that i should not build distributor as it was, because with megasquirt i can have full electronic BOSCH distributor. And this old part is just going to stand there and look nice, haha. I might think something other use for this, we'll see.

 

 

And sorry folks, one shipment from Australia wasn't complete, without this part i can't go forward with engine build. I'm missing one brass cap for my engine block. It's straight behind the camshaft. If someone could measure it properly, i would appreciate it! .

Got my build up and running again!

 

Pictures:

 

20130707_163851_by_atomicsickness-d6ce25

It's time to do something! Finally! So i inserted the camshaft to its desired place

20130707_163910_by_atomicsickness-d6ce2d

Then i found the missing core plug!! Its diameter is 45mm from outher edges. The bigger one below is 50mm.

20130707_180306_by_atomicsickness-d6ce2m

Here i just inserted the chain and it's important that you align those 2 dots together so the engine is synchronized.

20130707_203355_by_atomicsickness-d6ce3x

Sorry.. My hand are little bit shaky, dunno why :S but i inserted my new bolts there and timing plate + new water pump

20130707_184243_by_atomicsickness-d6ce2w

And i got an idea for my old intake. So i removed the carb. And made that little square there so i would make a bigger hole for air intake. What i'm planning to do here, is that i'm going to insert pressure chamber above this instead of carburetor. BECAUSE, this intake is water cooled!!! So after the intercooler, i would still be able to cool some of the heated  air before it goes to the engine, clever, eh? And no extra holes needs to be drilled, because this is original :) All i need to do is get new hoses for  this because the old ones were so crappy...

20130707_184252_by_atomicsickness-d6ce32

Here is the intake, and below the intake holes, you can see a small watercooling port (I assume) :D

20130707_184302_by_atomicsickness-d6ce39

Blaa blaa~

20130707_190345_by_atomicsickness-d6ce3g

So here is the bigger intake hole for the air, fuel will be added later than this hole. I'm going to use one guide that i have in my bookmarks, i may share it with u...

http://forum.diyefi.....php?f=24&t=421 <--- there u go :)

20130707_193435_by_atomicsickness-d6ce3l

And here is the intake after some glass ball blowing

20130707_193500_by_atomicsickness-d6ce3q

Looks nice, eh? And for those little screw holes, i'm planning to do rail mounts for the fuel rail, we'll see how it ends.

 

 

 

Alrighty, more pictures next week. I think it is soon time for buying megasquirt and some pipes for custom exhaust system. But before i start doing anything, i need to do some calculations and reading maximum boost ^^ Cheers!

Hmm, i noticed 2 notches there on my intake, any idea why in the earth?

Sup guys, made some research on intake manifolds for turbo applications. So i used this site to calculate my engine airflow for intake http://www.widman.bi...lators/CFM.html

And the difference is of course HUGE. without turbo it's going to take 168CFM (Cubic Feet per Minute). And with turbo 368 CFM (Cubic Feet per Minute). And this is approx. Engine size 1488cc And max RPM is set to 7000.

 

With this value i can calculate right throttle throat for my build. So the maximum air velocity of approximately 300 ft/sec will keep flow losses acceptable. And i got best results with 50mm carb (281 ft/sec) Any bigger and any smaller would cause less airflow into the chamber. And I can have that from from Saab 9000(it is using same throttle for turbo and non-turbo, at least i found it on ebay)

 

As for the plenum volume, it should be a function of engine displacement -- in general, 50-70%.

So in my case 1.488 x 1.5 = 2.232 liters

 

So i took 2 liter soda bottle and made this little body for my intake manifold

20130708_133358_by_atomicsickness-d6ci49

Made it like this, because now all the air is going to sucked through to end of the plenum as u can see here. And i made sure that my intake hole in the middle, which i made last time is bigger than the throttle body is going to be. So no back pressure there.

20130708_133409_by_atomicsickness-d6ci4j

Yea it doesn't seem straight because tape wont hold it all, haha. I need to make mount for this too...

 

 

In the next episode... We'll see if i can make this plenum ready and then i need to wait for the throttle body. After that i need to hunt some fuel injectors!

Hi guys, found some useful site for ya

 

http://www.gtsparkpl...orSizeCalc.html

 

For my 160hp i need (4)x 315cc fuel injectors, time to go shopping~

Found nice injectors http://www.ebay.com/...10874ce&vxp=mtr

They got bosch connectors, and that is very important! Because my megasquirt kit is going to include bosch connectors. So they're just snap in. And these injectors are suitable for most fuel types ''Alcohol, gasoline, E10 (Ore.) or E85.''

 

When i get those, i can finally start to modify my intake manifold. we'll see how it turns out! I think i'll be going out for now, gotta make that plenum :)

Adding photos, i guess it's just that i can remember what i'm doing,lol. This thread is pretty dead...

 

20130708_170809_by_atomicsickness-d6cq8c

Drew some pictures based on the original manifold...

20130708_171618_by_atomicsickness-d6cq8k

Gonna scan them on my computer on scale 1:1 and add them here, if someone wants to use it or something... Going to send these then to the factory and they're going to cut me some nice flanges.

20130709_234354_by_atomicsickness-d6cq8q

Plenum is looking like this, it's getting late 12 AM, tired... I might continue tomorrow

20130709_234447_by_atomicsickness-d6cq8v

More plenum parts

 

 

I might continue working with brake and suspension system tomorrow, i need to add some finishing touches.

Dang dude, I love all this work you're doing to it. Keep it up, it'll all add up in the end. And I really love what you did with the engine cleaning, and painting wise.
