Bolt on turbo kit (4 Viewers)

I've tried to follow this post by post and may have missed it, but don't think it's been written up yet - any chance can you give a comparison for driving impressions between the wet-1 turbo vs TRD s/c -as apples to apples as can be? More impressions on daily driving sort of comparison.

A lot to unpack there. I’ll give it some thought since I’m lucky enough to have both.

Figured you'd have intimate knowledge of such .
Selfishly I'm nearing having TRD rebuilt and then likely engine ;( and weighing option$ for the turbo.

Ok so turbo vs supercharged 80s...

I've had my supercharged truck since 1997. Been through two engines and three headgaskets. 100k miles ago I completely rebuilt the motor and upgraded what I could and then installed the supercharger after a break-in period. At the time I was over the moon because it finally felt like how the truck should have driven, power-wise, from the factory. Around the same time I did a complete 4" lift which included all brand new OEM rubber bushings. The truck is super solid and has driven very well. It does very well on the highway, is pretty good off the line (stock gears) and seems to pull fine on grades. I was happy.

Now I have the turbo truck. The turbo was installed on a truck with 175k miles and very little history known. I've since replaced nearly everything under the hood with new, or zinc plated, parts

The install time on the turbo is probably fairly close to the time it takes to install the supercharger. Hardest part of the SC is the crank pulley. Hardest part of the turbo is the oil pan or the vacuum hoses. Tough call.

The turbo truck sounds EXACTLY like a bone stock engine/truck whereas my SC truck sounds like its just angry, in a good way. Both have identical OEM exhausts. The turbo is a sleeper. You can drive all day long and really never be in boost so its almost unassuming. But once you properly adjust your accelerator cable, and mash on the skinny pedal, its apparent that there is a ton of power because you feel the pull on your body. You don't get the same feeling from the SC. The turbo just pulls and pulls and pulls. the SC seems to putter out a LITTLE at WOT. That could be from an intake leak I suspect.

The SC truck does fine going at elevation but it'll still bog down as your elevation goes up. The SC truck feels every bit of 8k ft. The turbo truck could care less about elevation. It just keeps pulling no matter what road you throw at it.

I am 90% sure I will be converting my SC truck over to turbo.

Oh, if only you knew someone who could put together a half decent turbo kit!


Interesting to read your comparison.

Ah the importance of testing. This is a small example of why it takes me so long to bring some things to market. Sometimes testing doesn’t give the desired result and so you need to recalibrate and test again.

In this case I completely forgot to secure the methanol injection hose that goes to the nozzle post turbo. This caused the hose to drop and get with an inch of the turbo downpipe and this melting the sheathing on the hose. Now the hose itself is fine because it’s stainless sheathed with a Teflon inner tube. It’ll be fine, but it looks and smells ugly. So new hose being made and new heat sleaving going over it along with something to secure it in place.

Have you looked at products like Aeroquip Fire sleeve?

sticking with PTP but I’m using firesleeve elsewhere.

I work in aviation as a mechanic. I have access to firelseeve in all sizes, for free typically. I have built turbo systems for the 3B and also for other cars. I use it on anything that runs remotely close to the exhaust side. I also use it to run any wires through that also are around the exhaust.

In the turbine areas of some aircraft I work on we also use it to protect the wires. It also offers great anti-chafe protection.

Anyways, your turbo system is a work of art mister! Maybe someday, if the Can to US dollar becomes on par again I will consider it!

Your comment about SC vs turbo and the turbo keeps pulling at altitude vs the SC dropping off is sooo true! TURBOS RULE

Cheers

You two are talking about two different applications. He does use firesleeve for the wires and hoses. Joey is talking about using a PTP blanket on the actual downpipe itself.

Gents, I do not post much, still a new owner of a 1997 Landcruiser, which I bought to replace my 1989 4Runner that burned up in my house during the Tubbs fire in October 2017 here in Santa Rosa. I have pre-ordered the turbo kit from Wit's End, just waiting for CARB cert and delivery.

I really want to do an air to water intercooler on this kit at some point and have been digging around on that. I ran across this supercharger kit from Australia that includes an intercooler in the location we would need it. I am wondering if we could leverage some of their work for this? They have already spec'd the front radiator, pump, reservoir, switch, and intercooler. The throttle body has been relocated upstream of the supercharger, so the intercooler housing is not direct bolt on.

Thoughts?

Thoughts?

Stick with front mount air to air intercooler, millions of ricers can't be wrong.
Plus It's perfect for 99.9% of your use.

Water to air has only one advantage, and it's questionable.
The flip side is, it's more complicated, more expensive, more parts to fall

To be fair A2W setups for the 80Series have been working out great. I’ve yet to hear about someone not happy about them. A2A is something I’m not pursuing at all but others are welcome to DIY it. Meth injection solves the issue plus can net you more HP by playing with timing but yes it involves the painstaking and arduous process of filling a washer tank full of...windshield washer fluid

Im currently working on mounting a 5 gal tank somewhere in the back with an easy access filler, low level light and an AEM flow gauge. Less fills more thrills! I'll post up if it works out. Waiting on some new exhaust manifold hardware to finish up the turbo build!

what nozzle you using? Go with the smallest you can find. That 5 gallon tank could last months depending on your driving. We are only adding about 100hp so no need to go crazy on the nozzle.

 

[NLXTACY]

Oh and my setup is using a vacuum/boost actuator that turns on the meth pump at 2psi of boost. Otherwise it’s off.

Smallest nozzle in the kit

186 at the base. 216 at the top of the grade.
Ambient temp was 71. 55 mph going up.
I’ve got Joeys modified fan clutch.
I was hoping for 180-190 temps. I’ll have to look into this.

Why? Nothing wrong with 216 at the top of a grade with a fully loaded 80. Oh wait I forgot this is the 80 section

 

[mudgudgeon]

To be fair A2W setups for the 80Series have been working out great.

In the turbo diesel world, A2W has proven to be deficient, particularly when engine cooling is at the ragged edge. FMIC is the most effective, and reliable, and cheapest.
Granted, the needs of a turboed gassed are a little different, the basic physics / thermodynamics are the same.

Probably a discussion for another thread

Im using the aem kit that has an adjustable controller. You can set at what boost it starts, and at what flow rate. Initial rate and top end. Top end I believe is more governed by the nozzle.I haven't tuned it yet but that sounds good, I'll start there.

@Irish Reiver when are you planning your turbo install?
