- Anthony Bruneni and Tim Mahoney are back to give another update on the DIY 'Till I Die LB7 budget build! On this episode the boys discuss why they decided to go ahead and take the engine out. Let us tell you, the engine was looking rough. This means the boys can now have the heads checked to ensure they aren't done and to make the injector install more manageable. Be sure to follow along with our DIY 'Till I Die LB7 budget build project right here!

Being an lb7 owner this series is awesome! Keep it up guys !!
Thanks! @hkzspoolin744
Getting in deep! If you have time you should try your hand at porting the heads, exhaust manifolds, up pipes, down pipes and I'd say turbo but you are already upgrading that. It was 100% worth it for me to do that when I changed the gaskets, studded and upgraded the injectors. 🍻 Good opportunity to clean and paint the engine too!
Love the idea @KooshdaakaaGarage ! Did you notice any difference after porting?
@@Duramaxtuner absolutely. The idea for me was faster turbo spool up at lower exhaust gas velocity, I talk about it more in my "Project LB7 Spool Up" Series. I did mine in steps. First I upgraded the driver side exhaust manifold to a BD full bore, then ported that and the other side. Then port matched the stock up pipes, upgraded the stock down pipe and port matched that. Ported the stock turbo housing (exhaust and compressor side). Lastly upgraded the compressor wheel to a billet aluminum 11 blade. That added about 4mpg and a much quicker spool up time. It seems like the turbo starts to kick in around 1400 rpms now. This also smoothed out the idle a ton. After a bit I knew I needed to address the lifted injector so I pulled the heads, rebuilt them, ported them, tossed in 45% over SAC nozzle injectors, slapped on new gaskets and studs. I lost all my MPG gain with the larger injectors and CANNED tune (still need to upgrade to EFI) but the overall performance increased significantly. I am using a PPE Xcelerator tuner in tow tune 2. I used to never limp the trans in this tune but now I have to be careful between 4/5 gear because it feels like the racing tunes did before I put in the work and will absolutely put the trans in limp mode if I lean into the skinny pedal too much. After porting the heads and installing the larger injectors it felt like tuning my truck for the first time all over again and made me re fall in love with the ole LB7. Much quicker spool up, very hard seat of the pants pull and screaming up to speed with a cabover camper is not an issue at all. Infact a newer 4 runner didn't want to let me in the merge lane and was content to run me off the road. Torqued up LB7 said "NOPE" and left him in the rear view mirror. EGT's stay pretty low under load lugging up hill in 5th and cool off pretty quick too. Perfect budget friendly performance upgrade.
@@KooshdaakaaGarage Thats great to know! We will definitely check out that build series of your's to see all the detail involved and how it turned out. Would be really interesting to see how they compared to a set of stock heads on the dyno or even how they compare to something like an off the shelf ported head. Might have to add that one to our video idea list.
@@Duramaxtuner Absolutely, I've been curious of the same thing. I don't have access to a dyno but I recently picked up an OBDLink MX+ which can calculate hp/trq at the crank and turbo boost. The turbo boost calculations match my actual turbo boost so the hp/trq is good enough for my diy driveway mechanic stuff. I usually take the hp/trq read out and subtract by up to 26% to get a close estimate of the RWHP. I'm curious what the power curve of the ported stock turbo with a billet aluminum compressor wheel compares to a bone stock turbo and a 64mm off the shelf turbo. Will is spool up faster and produce more torque down low under a certain rpm and if so how much? Is the juice really worth the squeeze or should a guy save time and spend the extra cash for a larger turbo? The whole porting package I did I affectionately call "The Kooshdaakaa Special". Kooshdaakaa in Tlingit legend is a fable humanoid shapeshifting land otter man with origins in Bigfoot/Sasquatch. I can say that the porting job and injector upgrade as a whole definitely turned Pigs performance into a thing worth of legend and it would be pretty neat to see what kind of results you get with your own port jobs. Feel free to use the name if you do the whole package deal ;)
Haha will do! Thanks for all of the ideas. We will definitely get them written down for potential future videos. If you would ever want to be featured on the Diesel Performance Podcast let us know! @@KooshdaakaaGarage
You guys are just way to cool 👍🏋️♀️🤗🤺
Thank you @JamesMasterPlaster, so are you. 😎
Hey from Cali , you guys are not changing out pistons right , just the head gaskets?
@SamuelLopez-tp9qq Correct we are just changing the head gaskets. No need to upgrade pistons at this power level.
@@Duramaxtuner does that mean you don’t have to machine the block or do you still have to?
The block stayed as is, no machining necessary. However, any time you do head gaskets you should have the heads machined so they will fit correctly. @@SamuelLopez-tp9qq
@@Duramaxtuner thanks , for the info. Looking forward to seeing how truck turns up.
Since you’ve gotten this far… what about rods?
@nono-fn3zc Typically anything more than 650HP you will want to upgrade your rods. Since we only set an HP goal of 600hp for this build we didn't feel that it was necessary. We have seen several stock bottom ends come though the shop pushing 650HP so we're confident stock rods will hold all the power we plan to throw at it.
@@Duramaxtuner600 is kind of like 500, Nick... it's great until you get there and then you want more :) :) :)
Know all too well how that goes. There's always a broken part waiting down that road though.@@nono-fn3zc
