Engine Build

Post by 93cobra670 on Tue Jul 08, 2008 10:16 pm

Ok, I figured that I'd post up some pics and what not of my engine build. I decided to keep the car, but as of now I either have shot rings or a cracked piston...so its time to do work son.

The plan:
Speedpro forged pistons
Moroso main cap girdle
F303-cam
1.6 roller rockers
porter heads and intake

Day1: Breakdown begins
-cooling system out
-supercharger piping/mass air out
-plenum off
-exhaust out
-battery out
-shifter out
-driveshaft out

Pics coming soon

Hey, nice pictures.
Did you lose a head gasket or is that just junk from removing the cylinder heads?
Are you running a stock oil pump or a high volume version? That oil pump pickup tube looks bent, or maybe that's how they make 'em.

the only junk from removing the cylinder heads is the coolant in the actual cylinders, and some of the garbage in the lifter valley. I did lose a head gasket last summer and since replaced them with felpro cometics. Awesome gaskets.

What that junk on the pistons is (especially around the edges) is gunk buildup from blowby, oil, and particles from the rings. I had really poor compression (should have made about 14-15#s of boost and only hit 10.45). I'll have my compression restored and will hold boost which is exactly what im after. I'll throw up another pic or two of that

As for the oil pickup, thats stock and I plan on leaving it like that. I just need to thoroughly clean the screen and I should be set.

so I finally have some parts...pistons and bearings came in, and I have the machine shop getting me a full fel-pro gasket set. Theyre also going to get me a ring compressor so I can hammer those pistons home. Looks like friday will be the day to pick up the block and fresh pistons mounted on the rods (need to have the wrist pins pressed). So that means the short block will be ready either friday night (if I have nothing to do haha), or saturday afternoon. I'll also throw the heads on, but need to wait for the cam and rockers to complete the motor. I'm hoping to fire the car up in about a week and a half. Heres some pics just for the heck of it.

latest update

Post by 93cobra670 on Sat Jul 26, 2008 2:06 pm

so, I got the block back from the machine shop, and i was really pleased. They also pressed the wrist pins for me. I started short block assembly last night and it started well but went downhill. I installed the crank, mains, and 5 of the pistons with ease. Then my dad decided he wanted to help out while I was dropping some dumpage....not good. Turns out he bent the lower oil rings on the remaining 3 Evil or Very Mad Luckily he didnt drive them down past the deck, so there was no cylinder wall damage. All I have to do is order a new set of rings, and just use those 3 rings which pisses me off. Anyways, heres a few pics for everybody

Engine rebuild

Post by ProfNichols on Sun Jul 27, 2008 8:30 pm

Hey, it looks pretty nice. I find that the hardest part is knocking the pistons into the bores without messing up the rings and keeping the gaps positioned correctly to minimize blowby. I have fallen in love with a special type of ring compressor tool; it is the best hands down and I was able to knock pistons in my motor all by myself (which is good since I am usually flying solo when I rebuild stuff). The blue band style compressor required me to have someone keep it aligned as I knocked the pistons in and I always caught a ring or two and had to restart the process. If interested, the tool is KD Tools (KD 850)...simple design and easy to use.

so today was one of those icky days where I cleaned some stuff up....primarily the combustion chambers. They were NASTY!! I would love to polish them, but decided to quickly degrease, scrape, sand, steel wool, and sand some more. Overall id say they are back to normal if not better. I also cleaned up the suparcharger oil feed and test fitted. All i need is some silicone plumbers tape to seal the threads up on the piping and i'm set. Also need to pick up some permatex 2b for the head bolts and flywheel bolts. Tomorrow the rings should be in so i'll get the remaining 3 pistons set, install the oil pump (oil pan needs to wait), and bolt the heads down.

Here are some pics of the combustion chambers, they were beat

so I got plenty of parts in today and yesterday, and knocked pretty much all of the assembly out of the way. Today i installed the cam, lifters, pushrods, rockers, timing chain and cover, water pump, blower braetck, power steering pump, valve covers, lower intake, distributor, and some other shit haha. I need to pick up some longer valve cover bolts because they barely thread...in fact 3 or 4 dont even reach. I plan on shoe horning the engine in as is, the installing the power ac compressor and blower when its all squared away. I won't be able to get the hoist until saturday, so i'll have time to clean some more stuff up and wait patiently.

Some pics

I finally got a hold of a hoist yesterday, called up some friends, and dropped the engine and trans in. Everything went in flawlessly. I ended up putting a little bit of work in with all the other crap, but called it quits to go out for the night.

Check list of to do's
-radiator
-exhaust
-driveshaft
-transmission connection/clutch cable
-a few vacuum lines

Hopefully i'll have it fired up tonight

took me 3 tries with the timing, but it runs really well right now. Still breaking it in/working out some small issues. Right now i need to rewire the starter, pressure test the cooling system because its eating a small amount, and paint the new hood and nose. Also needs a tune, im working off the old one and i cant hit boost for now

with the new hood u can really hear the blower....listen up in the vids

on to the pics
