Lgtvf52's journal & build


Recommended Posts

hey guys so I figured I would finally make a thread about my lgt from when I bought the car to its current state and build! sorry about being so long!

So lets get started shall we..

 

I bought my 2005 OBP GT limited in May 2013 with 110k miles. Bought the car knowing the PO threw 3 turbos on the car hoping the car would run right.. finally I got the car and had the VF52 rebuilt with a billet comp. wheel, while I was waiting for that to come back I checked the oil lines turned out the banjo bolt closest to the turbo was clogged and starved the turbo(s) of oil. replaced all the lines and banjos got everything back together. finally got it running.. was idling very low and wanted to stall after everytime I let off the gas. turns out it was the passenger side TGV was stuck closed, choking the two cylinders. Bought TGV deletes installed them, car still had a low idle higher than before but still low because the ecu still had the codes in the memory. Finally I drive the car a bit and decide I'm gonna go for a drive up the mountain and on my way there car was running good and i get about half way up the and white smoke everywhere!! shut the car off and coast off the road, opened the hood and the radiator blew (top plastic part). had to get towed home. ordered a mishimoto all aluminum radiator. installed then said great time for a tune and get the car running like she should. dyno tune at efilogics and the motor spun a bearing..

After the motor blew I was trying to decide if I wanted to rebuild the stock block and do some upgrades or just get a STi shortblock and throw it all together. I decided to pull the motor and rebuild the stock block, fast forward a little bit and we get the motor out and tear it all down and as you can see from the photo the bearings were destroyed but surprisingly the cylinder walls had no scoring or anything so I went and bought ACL main and rod bearings and new Manley forged pistons (kept the stock CR at 8.5:1). had the block honed and that leaves me sitting where I am right now as I have to wait to order the crank tonight or tomorrow! then its time for the assembly! also I deleted the oil cooler with the union from a 2.5i :)

Please chime in if you have any questions or suggestions,

Thanks for reading! :icon_mrgr

I'd get a new oil cooler. Just because it's a good idea, and may be a new coolant cross-over pipe as well.

 

Before you open the bearing box, make sure the new crank and the bearings you ordered will match up.

 

I know you have a local Subby guy, I just don't want you to find out the crank has a different size journal then the bearings you bought.

 

I think you have my thread from my rebuild.

 

Make sure you check all the small things, and clean the grounds and sensors well. Tighten the fuel line clamps, grease the starter shaft.

Why does everyone say to get a new oil pick up? Do they break easy? I have heard to replace it with a killer b oil pickup but what's the advantages? And will do byron! I have triple checked the journal sizes but will of course check again before installation and everything

The brass welds are known to fail causing oil starvation.

 

The reason most people suggest you fix this problem is it's cost effective when the motor is out. Plus after a rebuild to have a failure on a known issue would be... silly. $130 fix is cheap compared to a rebuild. I did mine or the shop wouldn't warranty the work.

hey guys so I still have not had time to get my crankshaft from the dealer so the motor is currently at a stand still. However I did receive my killer B oil pick up. looks great amazing quality piece and great welds. also had a question, when my motor build is all finished I will eventually need to get the car tuned and my thought was that instead of putting on the stock parts (uppipe, downpipe) again if I bought a Cobb AP and took one of the off the shelf stage 2 maps and adjusted it for the 650cc injectors and put on the new DP and UP would that be ok for the break in miles? or is this a bad idea? please explain. Sorry if its a stupid idea. lol thanks everyone

I finally got my crankshaft shipped to me! I dropped it off with my engine builder along with the killer B oil pick up and gates timing belt pulleys and tensioners so now we can actually start putting this thing back together. Cant wait to drive it again, its been way to long!

What's the gap between the bearing and crank ?

Is that just what you used for break in or is that what you are still using?

 

Sorry just saw this. Yes just for the first 2000 miles or then went to Amsoil European 5w-40 Full SAPS year round. My cars see mostly highway miles, so I'm not worried about the 40 in the winter. I also use their EA15k13 filters.

 

I have both banjo filters removed too.

Got the Manley forged pistons in the block...

Then the ARP head studs..

And as it sits right now... Full longblock!! just needs the cam gears, timing belt components!

 

Sorry about the poor quality photos!
