Builds LX450 where to start! (1 Viewer)

[concretejungle]

dude!! now you post that!! I mean I literally just cut into my fresh, brand new wiring harness over the weekend to splice in a rear O2 simulator. I would of loved to have that adapter!

and actually i see you posted that a while ago but i just now saw it. Damn!

 

[scottryana]

No, EMS went out of business a couple years ago. You are kind of on your own now for Turbo builds.

Finally read through this thread. I really wanted to go LS and now I'm doubting myself. I want a turbo!

Is EMS still in business?

 

[scottryana]

Haha yep I posted that weeks ago.

Damn. That's what I was afraid of. Speed shops around Dallas are focused on a small group of cars.

 

[scottryana]

Yeah I have found a lot of shops don't want to try something new because it becomes a crap shoot for them when they know exactly what to do with Subaru, Evo, Supra, etc. but Land Cruisers they have no idea what kind of prices to charge or how long things will take.

So it ends up being time and materials and your project gets pushed to the back while they turn out cars they know can be profitable.

But there is nothing special about the 1FZ except the closed loop operation. As long as the truck is post 95 OBDII you can add some boost with the appropriate sized turbo without worries.

Finally getting around to fixing the wiring in this truck. Should have been done a long time ago! Haha

Ryan,

Fantastic read took me about a week to get through it and cannot wait to get started on my 96' LX450!

Do you know of any others producing the Ypipe turbo manifold set up and down pipe? I see the CX racing but really nothing else. I am going to do my turbo set up similar to yours with the exception I plan to rebuild the lower end since I have 300,000 miles on the motor so I will also do the head and ARP head studs.

So other than the Meizer pump and A/W cooler core not being large enough are you happy with all the other components you have used? I do plan on the Haltec Elite, which one would you recommend for your set up?

I also wondered about compression since I am rebuilding the engine and head would it make sense to size the head gasket to compensate for boost compression?

 

[scottryana]

Thanks!

Well you might be in luck. Please keep an eye on this thread....

Bolt on turbo kit


Yes I love my setup and would only change the intercooler. I cheaped out and went with a piece of crap "Frozenboost" cooler. I would just get a real cooler from the start. The Meizer pump I think is not entirely Meizer's fault. I think it was a wiring issue, I am fixing the wiring and will get a brand new pump and see if it is the issue.

I wouldn't change the stock compression at all for the most part, unless you are going to spend a lot of money and then I would go from 9:1 to 10:1... but you would have to really take the time to get a good tune.

Yes I have been following that thread as well as your other build. I guess my impression of the bolt on turbo kit was that it would only be 60 to 70 hp increase to the wheels with the specific turbo you are going to spec correct? But with this new kit I am also guessing it would accommodate the same turbo or similar to the one you used and be able to handle 400hp and 15-16 psi?

 

[scottryana]

The turbo I am spec'ing is a 600hp capable turbo, if you do all the other mods, like injectors, stand alone ECU, valve body, etc. but that will not be part of the kit.

Awesome can't wait to see what you come up with.

This really has nothing to do with anything, but I thought it was a cool comparison. We often hear people say "I wish I had a LS", "man I wish someone would swap the 3UR", "The 80 needs an engine swap"

Well I just saw this 2013 200 series that was dyno'd with $1000 headers, full exhaust and its better transmission and the numbers were less than amazing.

3UR with headers and exhaust = 286hp, 317ft/lbs
1FZ with only 15psi = 318hp, 453ft/lbs
Both on dynojet 4wd dynos.

So before you start getting too crazy about tossing that old 1FZ aside, give it a little love haha.

 

[ThomasMore66]

So now our kit needs more boost. Bring it!

^^^ Top graph in RPM, bottom in MPH, so curves are hard to compare. Would like to see the comparison on the LS curve as well. They make power down low effectively. I'm watching the Turbo thread for ideas with the LX once I wrap up the Cruiser.

 

[scottryana]

Agreed it is hard to compare but if you want to do some extrapolation it isn't that hard. We know that torque and hp always cross at 5250RPMS. SO the graph that is in MPH you can see they will cross about 73mph. SO 5250RPM/73mph = ~72RPM's per MPH

Take any MPH on the graph and multiply it by 72 and it will give you RPMS. i.e. 50mph * 72rpm/mph = 3600RPMs @ 3600rpms turbo makes about 300hp and 430ft/lbs. The 3UR at 3600 makes about 205hp and 305ft/lbs. etc.

Unfortunately the first useful number from the turbo pull will be about 40mph or roughly 2880RPMS, simply because of when the operator started the pull.

[scottryana]

Terrible picture but the only LS LC I have found that was actually dyno'd. 227rwhp is much less than 3UR and Turbo 1FZ.

[ThomasMore66]

That’s sad.

On another note, do you think Robbie’s head work is worth the effort on a turbo engine?

 

[Cass007]

Can't see from that photo what type of Dyno is being used there. DynoJet to DynoJet is apples to apples (sort of based on settings), but a Dyno Dynamics is load based and will always yield a lower whp number. Where I came from in the tuner car world people played games with dyno settings all the time to manipulate numbers. I'm not saying this is the case here, just saying its hard to be really accurate unless the 3 setups were compared on the same dyno on the same day on the same settings.

I have an LS2 swapped 350Z and it makes a bunch more whp on a Dyno Dynamics than 227rwhp. LS2 is a few more cubes than an LS1, but the truck above isn't even running 4wd. That driveline loss must be staggering. My swap is stock other than an intake, headers and 3" exhaust with no cats. Guess I just expected more from the LS, but regardless I like the turbo idea on the stock motor more I think.

Surprised that someone hasn't tried a remote turbo where the spare tire mounts. It's not ideal for wheeling, but moves the heat further back.

 

[scottryana]

That figure of 227rwhp is about what would be expected considering an LS1 was only like 305-320hp at the crank. The 3UR with headers and exhaust should be close to 400hp at the crank and is only 286awhp. I think it is something many people do not realize. The stock 1FZ is 212hp and around 135awhp. We are not comparing if a sweet K&N air filter gave you more horsepower and it needs to be tested on the same dyno/same day, we are making gross generalizations backed up by moderate commonsense.

The remote turbo has been tried. It ran for about 2 years, changed hands and blew up on the new owner on the way home.
