@@tonyargo853 Well if they were tripling the power output to the wheel from stock that would be 705hp if were talking 86 and 735 if were talking 87. At that power level that POS 4.1L block probably split. The 3.8L block is a POS as well. It kills me to say this because I owe an 86 Grand National. When my engine was built I was asking about putting 600whp with it and my engine builder told me I need to step up to a Buick Motor Sports Stage 2 block or a TA Performance block. $15k spent on an engine block that will likely split at 600whp. Well that build did manage 625whp and 683ft-lbs and the block survived just fine though.
The build cost for this engine was somewhere around 12K, but that included a fair amount of used parts, including the turbo which the customer provided. The builder was KT Engine Development in Concord, NC.
I cringed as you drug the bare head across the work bench. Kind of like painted body parts on concrete without protection. I know that was the old head but still lol
Question. Way does the exhaust from the drivers side go into the back of the exhaust on the passenger side than into the turbo? Wouldn’t the exhaust meeting together before going into the turbo flow better?
Unfortunately, we never got to finish it. The owner took the engine and put it in his car, but before he was able to get it to a chassis tuner, unfortunately, the car was stolen.
Part 4 update-check bounced on $35000 engine build. Craigslist now selling engine for $15000. And rolling chassis available from different seller for $7500. Jk
Why not just use sodium filled exhaust valves and leave the stem at the original diameter? What was done to the bottom end? Also that valve spring squirter setup is interesting...I have never seen that before. Is this engine going to have a silly high red line or something?
+TurboMitsubishi If they are planning on making more than 450-500rwhp, they had better put center billet mains or an engine girdle and a steel crankshaft. The stock crank starts flexing at around the aforementioned HP. One thing they don't mention here is whether or not this block is 3.8L or 4.1L. In any event the GN1-R race heads are 14 bolt and they wouldn't need those heads unless they were planning on making over 700rwhp. Technically they could make less, but it seems like a waste if they are planning on making less. As far as the addition clamping force, I'm not so sure that is needed. I detonated with cometic and ARP studs, I didn't blow a head gasket. Instead it snapped my stock crank like a twig and destroyed the block. So that right there show that the cometic heads gaskets, coupled with the ARP studs provides pretty awesome claiming force. I'm in process of rebuilding a spare 109 or 3.8L v6 for my Grand National. I'm planning 600rwhp. For that, I got a forged rotating assembly, GN1 heads(not race ported) billet main caps for the first three mains. 218/218 roller cam and T&D roller rockers. Beehive springs and Comp Lifters.
+sinusbradycardia All of your points are mentioned in the earlier videos of the series. they went with a 4.1 (as an aside I would have gone with series III 3.8), they used a Girdle and much better crank and cam.
nox0underling Series II or Series III blocks, along with forged rods and pistons. If I could do that swap, I would. There are several guys that have done this swap and use a built 4l60e transmission. One example was a series 2 block with an fbody tb and intake, 98 fbody ECM, ported series 3(L32)heads and an older TE60 turbo. Tuned with an HP tuner. The first full 1/4 mile pass, the guy ran an 11.34 at 121 running 17psi of boost. I have the same turbo and I ran 25psi of boost and my best pass was a 11.70 at 115. The total cost, $6500. It cost about $9k to build a reliable low 10s 109(LC2) block. The S2 and S3 blocks are superior in design and durability with their cross-bolted center main caps. The guy who built this set-up, has ran in the 9's on a S2 block with S3 connecting rods and ported heads along with a forged aftermarket piston. Stock crank and main caps. Cometic head gaskets and ARP head studs.
Eh. I know these guys know what they are doing, but you don't install valve stems like that in aluminum heads. You gotta heat up the head first, then install. Same with the valve seats.
gotta see part 4 come on baby!
dumb question: Will there ever be a part 4 to this build???
5 years later, I’m starting to think not. What a let down. What was the point?
6 years later, i think not!
I completely forgot about this tread. It would have been nice to see to completion.
We can’t say they aren’t making videos, oldest being a week old. Come on guys! We’d like to see where this build goes and ends!

Is there a follow up with a part 4 conclusion ?
Where's part 4? I want to see the tune up and dyno results!
Ha! Actually, he moved to Texas (I'm in NC) and had the dyno tuning done there, so I missed it.
this is a batshit insane build...I LOVE IT
Those heads look like they will crack right between the intake and exhaust seats. Under all that boost, wouldn’t surprise me at all.
What were the final readings since there was no part 4 or do you know? Watching the 3 parts has me in suspense.
What happened to part 4???
Thanks!
Please show more
Thanks for the info. Would love to see more and how much hp it produces.
Wildy built!
the hg is the fuse ! u add the extra clamping force bottom end is going out
wheres part 4? i want to see it in the car and hear the motor running.. what a tease guys
I know it's probably an old head, but I died a little inside when he dragged the mating surface across the table.
You have to be careful with those shims and Lash caps They tear apart, pieces go into the oil pump making you lose oil pressure
dam i would love to see the finish product
Question. Way does the exhaust from the drivers side go into the back of the exhaust on the passenger side than into the turbo? Wouldn’t the exhaust meeting together before going into the turbo flow better?
Where is part 4?
I'm sure it would be worth every penny
is there a part 4 to this you dont show the completed engine or dyno test
Unfortunately, we never got to finish it. The owner took the engine and put it in his car, but before he was able to get it to a chassis tuner, unfortunately, the car was stolen.
Show me more!!!!
Here's a challenge for you,I drive 2005 Chrysler t&c 3.8What can be done to make it faster and more gas effitiant ?
Sweet videos but how much did that build cost?
How do I get my one of these completed motors for my GN?
+Detroiit 313 KT Engine Development -- ktengines@aol.com
Any new video of the gn? Wanted to know how fast it is?
Gotta love the t&d's
This engine was asking for the extra head bolts. In fact the heads had them ,hope the owner drills the block like it should be.
O man I'd love to drop my GN off to you guys and have that done
better bring about 20g's

Is there any way to duplicate the Buick V6 indy car engine ?
It's 2021
Still waiting on part 4
Sorry, but it won’t be happening. The car was stolen and never recovered
@@TheHorsepowerMonster Man that sucks!
Truth. In addition to the engine build, the guy had already invested a ton into his car. Thanks for watching

Best S3 3800 out there is also the fastest Grand Prix that is running, and last i saw his world record is 8.57.

A good harmonic damper goes a long way to help the crank shaft take more abuse.
Part 4? Did the customer run out of money? Ha ha.
Where at in NC?
If I get a GNX will you all do this for me
How much hp?I wonder.
Wheres is part 4 geez...
Eh. I know these guys know what they are doing, but you don't install valve stems like that in aluminum heads. You gotta heat up the head first, then install. Same with the valve seats.
What the expected h.p when finished!!??
What size turbo ?
Where's the rest?
What happened to part 4
what # is this gnx
If you are going to use so many aftermarket parts why even bother? Might as well switch to a V8.
wheres part 4
I guess there’s no part 4? Must’ve run out of money to finish the engine build....😂
Believe it or not, the owner put the engine in the car and was going to take it to be tuned on a chassis dyno, but it was stolen.
Only true buick is the grand National
3800 buicks are still buick motors. I'm wanting to build a turbo 3800 series 2 fwd sleeper car.
***** your lesabre t-type was stolen??
weird you guys in the US have FWD 3800. Like what were they thinking? In Oz we only have the 3800 I, II and II and a half and lastly L67 in RWD only.
We have the camaro and trans am with series II which are RWD. I'm sure there's a rwd series 1 car I'm forgetting
Part 4 doesn’t exist
God
The owner ran out of Money to complete the engine lol.
8 studs when you have 14?🤷♂️
