You boyz did a great job on that tunna and great job getting Josh on the right track

Nice, we had been discussing it too and I think he made the right decision. He actually made a few more numbernon the same timing too, but was seeing knock. Ended up 20hp down up top.

Keen!

Hahaha thats actually a pic of Josh... Thanks Sami 🤣

Yeah it was real nice to drive, just a shame I couldn't give it too much on the street 😅.

It's a real sleeper!

Thanks mate, hopefully it helps a few people in optimising their setup 🙂

Thanks 🙂

Oh nice, the extra cubes would be really nice for the 80mm. 3inch is very small for those cubes 😅 The s366 was really nice to drive!

It's a weird one, I would have thought the larger A/R would cause less pressure within the turbine section.. Could it be that the compressor requires much more energy to spin, causing more backpressure too?? Id love a bunch of sensors to know for sure!

DK ain't no Gaijin 😉. It's pretty awesome isn't it!

It was really nice to drive too, most people wouldn't look twice at it 😅

@@GapSauceKZfaq 👌😎 and like ya videos mate gave u a subscribe 👌😎 keep a eye out on mine I’m just about to get my GTSR back with a fully built DART427 with a Kong 2650 on it running E85+meth hopping to hit a 1000+hp 🤞🤞🤞

Thanks mate, appreciate it! That sounds amazing! The GTSR's are such a cool car and they don't take alot of power to really move either.

He's a beast!

Thanks man!

Yes some sick driving at the end

Yeah buddy!!

Ahh that's an interesting theory mate. Wish we had access to as many sensors as we could fit in the car to know for sure!

Yeah buddy! I think it was perfect for the street. Would make even more on e85 too, can't argue with a 4000rpm powerband if not more!

It is a much better car to drive now, especially as a manual.

It's very dependent on the pressure ratio of the turbine and the fuel used. I believe improvements could be made also.

Hey mate, the full specs of the turbos in in the description of the video. It's not that it had a backpressure issue, just that there was more backpressure as the gate needed the duty cycle adjusted (adding more pressure to the other side of the gate to keep the boost up) The s366 actually made a couple numbers more that the s480 on the same boost which backs the theory up. I'm not 100% on it though, so I'd love to hear everyone's thoughts. Is the larger compressor taking more backpressure to turn?

Great power for 15psi mate. Most 98 cars with 3582 make an honest 320rwkw and run 117-121mph.

Looks fun doesn't it!

@@GapSauceKZfaq great venue for supermotard also. Haven’t been there for years but hear that it’s a little run down these days

@@RedDuster yeah that looks like it would be fun! Maybe a bit sketchy for me though on two wheels 😅

Auto is a completely different ball game though. The S480 was taking several seconds from a 60 roll to even make usable boost. Crossover piping size and merge design would play a huge part in the spool too. This particular setup was night and day difference. There's only so much you can feed a stock bottom end LS1 for drifting. In this case the smaller s366 actually had less backpressure as it didn't have the larger compressor wheel to turn. Diameter is leverage and on the same timing, it actually made slightly more power on the s366. On an optimal setup with an auto, you could definitely afford to go larger without suffering driveability. I'm glad you're happy with yours 🙂 Also, we talked about advancing the cam a few degrees to bring it up again but it's responsive enough as it is. 🙂

Haha, it would definitely catch a lot of people off guard. The car is super clean too!

Nah just cam, pushrods and valve springs.

The turbines are very similar between the two and the compressor ended up moving enough air for 610whp on e85 but was left there for the stock bottom end. The car did alot of drifting sessions at the track at up to 7000rpm and plenty of street use, unfortunately we just saw the bore split just recently and a rebuild is in order.

Yeah cool, just check the specs and yeah pretty much same on exhaust side. How much boost does it run? Looked like about 10-12 ish? The response looks great, I would be worried about having too much boost down low and having a manual you can really load it up down low and fold a rod in a sbe

@@RedsProjects You can bring it in softly with the timing but from memory it was around 13-14psi for 610whp and survived alot of abuse. 550hp@11-12ish

@GapSauceKZfaq yeah it looked like the car loved the abuse from the last part of the video. I see a lot of sbe drag cars are doing their best to keep the boost and torque in low rpm down to keep them alive at high power figures. Have you watched any videos from squirrel tuned?

Hey mate yeah just the stock radiator with an inline cap and an overflow bottle

Definitely could, but we thought this represented the majority of street cars here, stock bottom end on pump fuel. The car did make 300rwkw n/a as well 🙂

@@GapSauceKZfaq No no I liked this very much. Like you said, majority street cars/people would just go big turbo bigger is better mentality. Very little loses up top, big gains down low

Thanks for watching mate 🙂 I'm keen to get some more testing done! The s366 actually made a couple numbers more before timing was pulled for safety. Cool hey 🙂

Really? I wonder if they used a t6 manifold with t4 adapter or something.. from a physics standpoint, that should make sense but you never know!

Same exhaust mate. 🤔

Hey mate, all the turbo specs should be in the video, but I believe the turbine is .91

Nice, auto trans? E85? I'd be interested in seeing you pressure ratio.

@@GapSauceKZfaq Yes 4l80e, triple disk lockup , it's a tight converter 3000-3200 stall. I switch between pump e85 usually e50-55 and pump gas with water meth. The e85 definitely helps a lot with making power . The pressure ratio is through the roof I can tell lol definitely 2:1 . I have a wide LSA LS9 factory cam minimal overlap might help with high pressure ratio.

Haha, I heard he was the stunt driver for DK in Tokyo drift 🤫

Thats Definitely something I'd love to do!

Correct, and maybe let it feed, Say to 15-17psi.

Josh ended up running e85 on this combo and made a touch over 600hp, I believe it was 14psi. S369 would be a good upgrade if you wanted a nice 650.

@@GapSauceKZfaq Just wanted to add to this. I ended up going to a 1.0 AR housing. No change in the tune. The only difference I can really tell is the turbo spools slower. I'd imagine there's less back pressure thus helping hold boost later in the rpm range. I didnt mention before this on a 5spd truck. It's kind of a give and take situation. I miss how easy it was to make it spool when just cruising around. But the point of it was to gain some top end at the drag strip. Not sure if ill stick with it or not. I'm really not sure if its better or the same. Regardless the s366 is small for a 5.3l and it chokes bad up top. I have to ramp boost up just to hold 14psi. I've never been able to hit and hold 16psi. But if you want to make under 600hp its a solid choice for the street but not the drag strip. I've never ran it with open exhaust. I run a 3.5DP to 3" that exits in front of the back tire. This could be part of the issue. Very curious how the 74mm turbine version would do. Maybe a 69/74. Best of both worlds?

@@or-ian6973 Interesting, you could add a couple of degrees advance to the cam, or go a custom one. (Happy to help there). Spend some time on the injection angle and timing as boost is ramping. Wrapping the headers will help somewhat as well for spool. You can make over 600 on an LS1 so you should be able to do a little more on the 5.3.

Nice list of cars there mate! I have a few that I will always miss, My Cammed T2 TE50 manual is at the top of that list though.

I'm likely going to run the g42-1450 on this 5.4 but it's more for roll racing and drag application with n20 for spool if required. You could go for an sxe s372 as a middle ground if it's a 5.7/6L?

@@GapSauceKZfaq I was thinking of going with a g40-900 or g40-1150 since its primarily a street car. Stock 5.7, 98 only as I can't get e85 where I am.

​@@vongdong10If i had enough time and money i would love to throw a g40 1150 on it and compare to the s366

I like the thinking, this particular car made 385rwhp n/a. 620hp on 13psi from memory on e85 before it split a bore.

🤣🤣🤣🤣 Some sort of Wizardy..

Haha! I have lost two over the years but apart from that they have been fine even with being swapped over many times. Nothing else holding them on either.

@@JoshJ285 impressive, I was sure it was going to be cable ties even though i couldnt see them. Respect the sleeper look dude, 100%.

@@thatguyben3128 Nah that would be a good idea but i would be too concerned about how shit it would look haha. Thanks man.

Zip ties 🙂

Hi mate, it may be in the video description. If not I'll find out for you 🙂

@@GapSauceKZfaq shit it is there youre dead right!

@@danielbullock445 It drove really nice on the street, I was Impressed at the response.

Yes when doing the cam kit. It has dual springs.

Vcm 710 232/234 110 LSA

It's a surprise to alot of people who were told it's the best turbo for the application, I believe this was sold as a kit with the recommendation for the s480. Josh decided he could do better and made the swap and he's stoked. You would be surprised how many people have told us swear that their s480 still spools like the s366 in the video. 🤷‍♂️

I'd love to find out! Josh is about to make the swap to e85 and share his results with us in regards to backpressure and cooling etc.

@@GapSauceKZfaq the older sx s366's will go farther than the new sxe.... you will see on the dyno if you try it. sxe does NOT have a "clipped" exhaust wheel. Older s366 will go 50-100 hp farther depending on displacment of engine its on.

Sounds about right mate.

You have a few extra cubes which will help, it would work alot nicer with e85 and an auto trans with an appropriate stall. It all depends on personal preference, everyone likes to defend their choice. There's a big difference between what "lag" is acceptable at the strip vs on the street. Josh's vx would take several seconds to hit usable boost from a 60roll in 2nd which meant he had a hard time roll racing at powercruise.

I'd your intent is to keep the s480, fab the largest dump you can fit in there, ensure the crossover pipe isn't excessively large and I'd exhaust wrap anything pre-turbo (Inc dump) this will all work towards better spool and a reasonable boost threshold.

@@GapSauceKZfaq its a 6 speed , I'm too far into the build to quit now. I have 2.25 inch crossover into a 3 inch flange. We'll see what happens man!

Keep the 6speed, loads more fun!

3.5 inch dump into twin 3 inch into twin 2.5 inch cat back.

SXE

@@GapSauceKZfaq dang I just ordered the sx for my 5.3

Hell yeah! Both turbos in our test were SXE. What's the 5.3 setup? Those things are really nice.

@@GapSauceKZfaq just stock 5.3 with a 216/220 cam. Planned to run a s366 since I started the build. Nice to finally see someone post some good footage of one. Hard to find much info on them on a LS on YT.

Hopefully the old style sx is somewhat similar to the sxe. Not looking for much power so I’m not worried about that.

In this case, it was sold with the kit. But Josh wanted a more refined setup, and I think he got it!

@@GapSauceKZfaq sweet as. What cam and diff gears?

@@toneabet6252 Hey mate vcm 710 cam ans stock 3.46 diff gears

@@JoshJ285 awesome. Nice work

Stock bottom end, cam. Made 300rwkw n/a

@@GapSauceKZfaq do you know how much ls2 can handle with boost application and stock bottom end? I mean maximum hp without harming the engine

@@abdullahalaraimi6087 Guys have been 8s with stock bottom end LS2's. I'd consider upgrading the rod bolts if I was going to spin any rpm/power though, and stay away from the limiter

At the time of this video it was running 98. Later upgraded to e85 and made a touch over 600hp. I believe he just upgraded the fuel system in it actually recently. I'll have a really nice video about building a hard line fuel system in the next month or two, surge/fuel cooler etc too.

@@GapSauceKZfaq true that's pretty cool I'm interested in seeing how he kept the dead head rail on this car and if he mounted the reg under the vehicle or if he kept the dead head reg in the tank

​@@rubberbandman2540Hey mate at the time of this video it was just the stock reg in the tank and a walbro 525 with upgraded wiring to it. Ended up making 610hp on e85 with that set up. It has since been upgraded to a surge and manifold referenced fuel pressure reg

@@JoshJ285 cheers bro for the reply I'm about to use a $366 turbo on my cammed ls1 so you information is very handy cheers
