Building a 1000HP LT5 Corvette C7 ZR1 Crate Engine For My Ultima RS!

[@DriveDriverDriven]

Can't wait to see the build! The orange is such a killer color, that was high on my list for the OG Evo build.

[@UltimateUltimaRS]

Thanks, Will! I can't wait, either. Hopefully I can get it done as quickly as you built the Blunicorn.

Nice build man 👍🏻 “ya he drives a Honda Accord” 😂

Lol! Honda Accord! Yeah brother we are a different breed of man!

[@davesmith6754]

Love your build and all the colour combos are EXACTLY my taste 👍... Can I ask what U do for work cause it looks like you have ripped a brand new motor apart before 😁

[@UltimateUltimaRS]

Thanks Dave! I actually work at a law firm but have always tinkered with cars since I was a kid. I actually found a step-by-step how-to on Corvette forum to install heads and cam so I just did that exact thing. I've always been meticulous when building things so that helps too. Thanks for the comment!

Watching the video made me wish I'd gone to school for this. Truly MASTER CLASS...

[@UltimateUltimaRS]

Thanks Paul. No need to go to school for it! Just watch tons of videos and read as much as you can to learn, then dive in. I didn't go to school for any of this stuff either.

[@douglasfreedman9230]

Build Looks great, I’m also building a LT5 RS. But mine is a stock LT5. While your waiting for your kit, there a few minor mods on the engine you could do now. The AC compressor needs trimming for the engine mount, the thermostat gets drilled, and if you are using an analog oil pressure sensor look into a making a custom adaptor. Lastly we need to countersink one of the engine mount holes - I used the mount as a guide.

[@UltimateUltimaRS]

Thanks Doug! It's Gabe here... we've already talked. Thanks for going out of your way to help out!

[@douglasfreedman9230]

Ultimate Ultima RS oh now it makes sense. There was no name on the video. It’s a great video. I just got my charge cooler back from the radiator shop. I needed to get new bungs welded in. My first real oops. I should make lots of progress this weekend. Finally done with section one of the build manual - chassis.

[@Acrowat40]

Any chance of build videos...?

[@UltimateUltimaRS]

@@Acrowat40 The kit is currently on a ship en route to me. I'll definitely be posting build videos. Stay tuned!

[@quickisgod]

As a guy that is ocd about certain things looking a certain way... It bugs me that the supercharger cover still says corvette. I think I would have had to #1) Have that milled off so it's flat, and #2) Have it powder coated to match the valve covers. Also, the flat area would give you the ability to add something custom there to really tie the car together. Aside from that, I'm a big fan. Awesome build. Came out amazing, and I'm currently in the process of watching it all the way through. Great job man.

[@UltimateUltimaRS]

Thanks man. Definitely some good points here and I agree it would look better without the Corvette lettering.

[@wazzawalker6536]

Hope to see the finished build on a hub dyno, can't wait.

[@johnclark1925]

You know mate I would love to see this in real time, in a series of videos with some voice over explanation of the whole process... it would be incredibly valuable. Please consider doing that sometime as it would be looked at by many people not just car builders as it would be a good strip and rebuild reference. Cheers. 😎👍

[@romeropostali520]

That’s a lot of engine. I have seen a 2001 Ultima in person and it has a 5.7L LS1 in it. Camaro spec with 325hp.

[@kevinbarnbrook4728]

Ultima have three engine sizes, this is the LT5 which Ultima say you could get 1200bhp when tuned.

[@itlcurtis]

Good luck, I'll be watching with enthusiasm. This is my dream build (been following Ultima for over 15 years), maybe in a few years 🤔. Great video, keep them coming 👍

[@drtidrow]

1000hp LT5 in a 2300lb Ultima??? That's gonna be nuts. I am _very_ jealous! ^_^

[@rob105motorsport]

Looks good, mate! That LT makes the 650hp in mine seem mild. No deleting the variable timing? I believe Katech do that on their big power builds as well as a 112mm throttle body. Keen to see how it all comes together!

[@UltimateUltimaRS]

Thanks, Rob! Yeah the variable cam timing is deleted... you can see me take apart the cam phaser starting at 4:36. Katech does a whole revamp of the VVT which includes using a different type of cam, an LS3 style sprocket, and a different timing cover which I didn't find to have any benefit over the simple Comp Cams cam phaser lock. The Katech solution is like $600 vs $65 for the Comp Cams part.

[@rob105motorsport]

@@UltimateUltimaRS Interesting. Without having seen that cam phaser, I was wondering what you did to it. I assumed it was replaced with a standard billet set like I have on my LS3. Looks like you’re across it all and it’s good to see you being smart about spending rather than simply throwing cash at solutions without investigation.

[@goretro77hobbies]

Geezus what a beast of an engine.

[@christyrrell9762]

Hi from Australia. With the effort and expense you have made, I am surprised you didn't degree the cam. Cheers C

Great Video! Any reason for taking the sump off? Stock injectors? Stock oil pump?

[@UltimateUltimaRS]

I think I needed to take it off to access something else. I can't honestly remember. The direct injectors are stock, though the cam has a +38% fuel lobe on it. The port injectors are ID1050X. Oil pump is stock.

[@DetachedGarage]

Great work! Any news on when your Car will arrive? Looking forward to the rest of the build!

thanks for this videos, are amazing. keep them coming! :D

[@macthewind]

I am contemplating do an LT swap for my 86 Caprice. Trying to see if I should drop to an LT4 or still do LT5. Most likely GM won't being doing an LT6 crate for a while. Thanks Couple of questions: 1. What is the difference between LT5 and LT6 (if known LT5 755hp, LT6 650hp)? 2. Why did they only do 1 yeah of the LT5 (If known) Thanks

[@UltimateUltimaRS]

The LT5 is a cam in block, overhead valve engine that dates back to the small block Chevys of the 1950s. The LT6 is completely different with its over head cams and flat plane crank. I would put an LT4 in the Caprice since the LT5 has very little tuning support compared to the LT4 and the LT5 has been discontinued. I have heard the LT6 will be offered as a crate engine but I can't imagine it will be less than $30k.

[@bernardwarr4187]

Another great video. Great engine and awesome power. What other power unit did you consider? What unusual European engines are people running in these Ultimas?

[@JphoenixK]

Did you choose the V8 for the money value? What other engines have you considered inserting for your drivetrain?

[@UltimateUltimaRS]

The engine with ECU and modifications was over $25,000 so it wasn't exactly cheap, but if money was no object, I would have loved a Judd V10.

[@JphoenixK]

@@UltimateUltimaRS I watched an amazing time attack orientated A90 supra build with a Judd V10 from Ryan tuerk, i think it would've been cool with a high revving v10 in your kit car build but i heard the engine rebuild interval is like 3k-5k miles or something? sounds like a pain

[@carguyuk7525]

Why do you want 1000bhp. For track use its probably too much unless you somehow increase the down force and have a fancy traction control system. Hope it delivers what you want. Great channel and great project.

[@UltimateUltimaRS]

This is a common question and "purists" seem to disagree with the power output by usually saying it isn't "needed." But really that's the whole point of the car- there is absolutely nothing practical about it and zero need for a car like this even with 200hp. I used to have a Gen 5 Viper with around 700hp and it drove around just fine, but there are guys who put down 1800 to the tire on a 19" wheel in some twin turbo models. They're all over KZbin if you want to check them out and I've never seen one of the owners get out and say, "It's cool and all, but I just wish it didn't have that much power." I don't mean to be snarky or anything, but that's just my view. Thank you for the kind words as well!

[@hughmongous6613]

@@UltimateUltimaRS Agree@ 100%! You can never have enough power!😄👍

[@MikeF055]

If it's not port-matched, then do it yourself. From what the legs we see have done, it is ezpz for those legs.

The engine was done for a few months before the car arrived and I did end up taking the blower off and port matching them. It was very simple and straightforward!

[@dave5833]

You hav a serious set of Skill Sets Counselor well done. Only a gear head would understand.LOL

[@cindybb1869]

Did you use the wire harness & LT5 Computers that came with the crate engine & did you have to have HP brake in to the computer so you could tune it because of the new cam.

[@UltimateUltimaRS]

I used the LT5 computer and used HP Tuners for tuning. The good thing is that the crate computer comes unlocked from Chevy so there’s no need to send it to HP tuners. You just buy the credits and tune away.

[@chesspiece81]

Sequential transmission or DCT? If you go DCT and manage to get it to hook with the torque band that happens as early as yesterday in that LT5 hold on!

[@ultimaevo77]

Awesome build! do you know what the weight of the fully dressed motor is?

[@UltimateUltimaRS]

Fully dressed I would guess right around 510lbs. Mike Finnigan weighed an LT4 on his channel and I believe it was ~465lbs. The LT5 will be slightly heavier with the larger supercharger and then the alternator, AC compressor, and pulleys are a little bit as well.

[@chesspiece81]

You should mill the lid to instead of saying Corvette LT5 you should mill all the raised surfaces and have Ultima LT5 or Ultima RS on the intercooler lid. Something to keep people scratching their head. Especially if you do a coil relocation and valve covers.

[@westtexas501]

was that a phaser lock out i saw get installed ? what is the reason why your deleting vvt ? 🤔

[@UltimateUltimaRS]

All the high HP LT engine builds I've seen delete the VVT. I modeled my build after the "ZR5" package by Advanced Modern Performance. I also wonder how much the VVT works in the crate engine since I know DOD does not work, even though the engine has the ability to. That's all because of the tune though.

[@westtexas501]

@UltimateUltimaRS I too was also wondering about the DOD until I saw the block off plugs go into some oil ports, best off without that junk anyways they use different lifters that always collapse and fail with the dod system . As for the vvt system iv heard it helps make more lower end torque and higher hp in the higher rev ranges , but then again with the power goals your aiming for who knows if the stock phaser can handle that type of power. bad ass build by the way.
