BonneMe's Performance Build Worklog
 

Hey all, picked up the engine today from zzzzzeke (his dad's motor really). We talked it up for some time, then i drove back. Rented a tow behind engine hoist (with engine in the back still) hooked up the hitch and ball, and went through Cedar Ave rush hour traffic to get it home.

Got the front exhaust manifold off, drained the remaining oil, and got her on the floor. PIctures to come soon!

hopefully this rebuild will turn out better than DrJays. Do you have some literature that tells you how to do everything?

Excellent! Can't wait to see it (rebuild) in action! :D

The engine is a 93 L27, and i guess it spun a bearing? Yup i've got the reading ;) I'm actually not rebuilding this engine. I'm modifying parts from it, and adding new ones when i put it all on my block. Part of taking this apart is learning all the things you don't read, or see right away.

For one week this summer i'll be in my garage doing...
Major P&P on Heads, Throttle Body, Lower intake manifolds, Exhaust manifolds, a custom cam regrind, longer and significantly ligher pushrods, Full gasket replacement, timing chain replacement, and a Jet Stage 2. I'll also clean up and paint some of the parts too. :wink: If i don't pop my hood in rockford till i hit the dragstrip, then i'm probably hiding something :twisted:

The only things i'm not doing is the cam regrind, unless i can get a guy at school to do it with the specs i'll be using. :twisted:

Running build cost = $100

PICS! PICS! PICS! PICS! PICS! PICS! PICS!

Am I making myself clear?

This is an awesome project, we all could learn something valuable here. :shock: Hey I can be serious sometimes! :wink:

build cost is going to be a little more than 100 machining isnt free (but if you have some body to do it for you) ?

I'm doing the P&P work myself!!! The only thing that's gonna need to be done outside of my world, is the cam regrind. I've got some pix right now, but i'll upload them when i'm at school on monday.

The old motor is Dirty! THe oil in it was black, but the coolant was still pretty green, i saw plenty of that come out. :roll:

Hey Jason, when you swap the P&P parts onto your good engine let me know. I am interested in picking up the manifolds for P&P'ing on Ol' Blue.

are you P&Ping everything or just the manifolds? Remember it will only flow as much as its narrowest pipe.

The biggest restriction on series I right now, seems to be the Upper intake, and exhaust manifolds. Only time will tell ;) I think the biggest power adder will be the cam hands down. After that it's a tossup between the chip, and the P&P work?

the P&P will probably help the cam a ton. Isnt there an aluminum intake for series 1 that you could play with?

Thanks for the advice/support, but since there isn't much interest in my work, or anything, i'm not going to do this thread anymore. I'll probably just keep anything on my site.

here's some pix from this weekend.

I agree the P&P + cam will do wonders for you.

BTW, I'm sure we'd all love updates every now and then. ;)

I'm still waiting for pix..... :yawn:

hehe

looks like progress...Ill be looking for updates if you wanna put them here.

Not interested! No man, you got it all wrong, We just don't want to fill this thread with worthless dribble! Post away, Please ?

we are standing by for updates...not much to post about if we dont know whats going on!

stop being stubborn 8)
tell us whats up

Nothing new, i'm just sitting at school still for 2 weeks.

Very nice, I'm interesting to see your progress. Just like you I have to wait another 2 weeks until I can do SOMETHING other than punish my poor brain.

call me the old thread reviver
 

okay, so this is several months since the original post on this, but since i noticed that in your sig, the donor is no longer sitting on the floor, would it be prudent to assume that you've made some progress?

I've got an idea for your rebuild. Your gonna need longer pushrods for the decrease in material on the cam. BUT y not deck the heads (you would have to find out how much) to compensate. You would be raising the compression and saving money on custom pushrods.

What do ya think?
I hope your still doing the rebuild.

Actually.... Plans have changed. I still have that engine, but i'll be modifying it's heads for sure, and keeping parts for spares etc.

I've got parts coming to me this weekend, but i can't start on it till i have a custom computer with new fuel tables....

he wouldnt necessarily have to change the pushrod length if he has the stock rockers will he?

If i had a cam regrind, they grind it down smaller, for the shape of the lobes. Longer pushrods would be required to get the full desired lift.

I understand why you need longer push rods but y not instead of changing the distance from the cam lobe to the rocker by altering the length of the pushrod, mill/deck (take material off the base of the head) to alter the distance from the cam lobe to the rocker.
You'd be raising the compression. This is just a thought, i have no idea how much you would have to deck the head or if you could do it safely. I'm sure you can find someone that could tell you wether this would safely work or not.

Do ya know what i mean?

i was thinking of a new cam. :oops: If he raised his compression he would have to run premium fuel.
