Carnage pics, new build, VIDEO startup last page

Hey guys I figured I would post my new build and some destruction :) But first some carnage!
It was kinda lame on how my engine went. I was at the parking lot at work doing 15mph and slowing down not even at 2000rpm when I heard a loud *bang* and followed by some rattling noises then the oil light came on. So I quickly shut off my car and was in shock. Looked under the car and freakin oil everywhere and pieces of aluminum. Pop the hood open and there's a freakin crack and a hole on number 4, right where it says D16Y7 on the block. I'm thinking I snapped number 4 rod at 15mph under vac!!! this is crazy!! Boosted for 5yrs and the last year was recently street tuned on Ectune. Conservative tune on a greddy 19t @10psi daily driven.

trans bell housing got damaged. Numbers 1 2 3 rods are fine and seems to be intact, but number 4 totally trashed everything!








Couldn't find number 4 piston, it just disintegrated. All I found was the top piston ring.

New build and setup.
Y7 block
75.5mm vitara
FJT custom length I beams
Y7 head ported and polished by Dustin of Performance Porting
Bullseye Power 50trim

Donor engine is a D16Y7, unknown mileage. Picked it up for a good price. Engine came with the trans and cylinder head. Started to take it apart and inspect the block and all the parts of the engine and it seems to be in good condition.


A little dirty but with some cleaning and degreasing it will be alright. I can still see the factory hone on the cylinders.


So far so good.



Crank journals are in good shape


No toasted bearings! :D


Cleaned up the block, the crank and old bearings. I wanted to check the main bearing clearance of the "old" bearings to see how healthy the engine ran before and to just know what the overall condition is. Surprisingly, bearing clearances are still within spec.

Also measured the crank journals and checked for run out and its within spec.

that is some carnage, damn thats surprise that happened at low rpm, low speed, and in vac. What was the cause of failure, any idea?
To tell you the truth, I don't know. I remember that day being windy as hell and cold as shit. I think it was like -1deg with the windchill or something. My car was running at normal temp and the oil pressure was good and then boom!

So the build goes on and I pretty much measured the cylinders and pistons since I got the tools for measuring. Numbered the pistons for each cylinder and gave all my measurements and the p2w clearance I want to a machine shop to get it bored and honed. Also I told the guy to hone the walls using a 440grit @60degree angle hone.

Tools I used to measure the block and piston


New Bullseye Power T3/TO4E 50 Trim .55/.60 ar from FJT! it's sexy!



I emailed Bullseye about the Garrett cover and they told me their covers were out of stock and in order so they gave me that cover which is fine by me.

Polished crank, no grinding just chamfered the oil holes


Notched, Cleaned and Hi-temp painted block. BTW I notched the block before it got bored and honed.





Just the stock resurfaced flywheel


Y7 cylinder head intake/exhaust ported and polished, combustion chamber also polished



Re-measured the block again after the bore/hone just to make sure the guy did it right which he did. I aimed for .003 p2w clearance. Then filed my rings accordingly which was a pain in the ass but got it right the first time. I will be using a Bisimoto turbo cam on the head.

New honda rod and main bearings are going in the engine. I just placed the old ones in there to protect the bearing surfaces, basement gets pretty dusty. If I put everything back together on the engine stand without the trans, how long can I have it on the stand? it's not going to damage anything from being on the stand right?

Woah, someone who can use proper tools for measuring stuff. I like seeing that. =) I hope this block lasts longer than your old one.
I hope so too!:) Yeah the machine shop guy wanted to also charge for measuring so I measured my own parts to save $$$. Also used the same tools to help a friend build his sbc monte.
