i suppose that is relative to each engine. we have a 3k+ HP hemi in a funny car. aluminum everything...

Everything you need to know is here: Transgo 340-hd2 install and reveiw

I bought mine from Summit Racing here: Free Shipping on Orders Over $99 at Summit Racing.

You may also want to consider switching your trans fluid to full synthetic. The valve body upgrade worked even smoother after I made the switch.

But no water jackets........

...and torn down after each quarter mile run

Yea, no cooling system and aluminum rods. The pistons and rods get replaced all the time. I wouldn’t doubt the exhaust valves do also.

I am referring to longevity and durability. As my v6 has 260k on it and never opened yet. I cant see the 3k + engines do that as they sacrifice everything for the hp for one shot. ;) [ Not that one shot isn't a good time]

I may in the future switch to electric motors in place of the ICE engine for a vehicle. As our battery technology is starting to get there.

I live in the natural gas belt. I plan to switch to duel fuel system as from my research it burns a pile cleaner then gasoline which extends the life of your motor oil. Being we have fueling stations near by and a gas well on the property here. I was thinking on heading that direction for a few vehicles. As with the kits today that can be purchased. They let you use both fuels.

Probably do nothing for HP but we all have to tinker with something.

That stud girdle helps by keeping the block and crank in line at all times. The extra combustion pressure of the supercharger tries to push the crank out of the way.

Europe, England in particular, has kits to convert your rig to Natural Gas. A few members on the grand Cherokee had that done.

You can buy an electric motor that bolts in place as a section of your driveshaft by shortening it and run a bank of batteries and a speed control. Popular Mechanics did that to a Dodge Charger a bunch of years ago. It was cool.

Well, checking with the guys over on CT to see what they're doing.

A manual trans swap may be a way to get what I'm after from a driving experience perspective and might be simpler long term.

If anyone knows where to get the manual trans shifter bezel boot thing for the dash I'd appreciate a link. Seems they're no longer available and discontinued. I'd like to get one and have it on hand just in case. If I can't make it look factory it's out.

P/N 58804-35060 (yes I've searched Google and Ebay, hoping someone has further info)

Have you checked out Tom's Turbo Garage on Youtube yet? It's an LS swap, but he just got done doing it to a 2004 2wd Tacoma, which as you know has the same engine bay as our generation of 4Runner. He did it with a rear mount turbo on it. With 4wd, you'd have to deal with the limited space under the oil pan, but it was a really cool series he did with lots of details.

How about a 2JZ swap? I won't get into detail about how strong these engines are, there's already tons of info out there.

Like a UZ V8 swap you'll have to move the driveline back almost 3 inches, but no body lift required. Look up 1st-gen Tacoma swaps for further info.

Tweaked Performance has built a wiring harness for a 1st-gen Tacoma that plugged into the existing chassis harness that even kept the OBD2 components (guy lives in an area requiring emissions testing).

Donor vehicles used A430 transmissions so you may be able to reuse your existing transmission with the proper bellhousing and toque converter). You mentioned a manual swap, the R15x series manual transmissions from the 4Runners/Tacomas bolt up to the 2JZ (there are bellhousings and flywheel/clutch combos readily available)

@weekendclimber I've got his series queued up so I can watch it next week while I'm at the gym. An LS would be right up my alley and I'd get the sound I love to boot. I've never swapped an engine, but have some good friends close by that I learn a lot from

@Ed_C I briefly looked at that but there were lots of comments about fitment challenges. I don't wanna have to get too crazy cutting up the body or anything like that. Again it has to look factory.

Well CT may be a bust. Not one response in 24 hours to my question over there and only 16 thread views. Of course I searched but nearly all the threads I found were over 15 years old. It may just be this platform has aged past the point of anyone really having interest besides us enthusiasts.

Nice thing about his setup was, if I remember correctly, there wasn't a whole lot of fab work he had to do to get it in.

I’d be interested in seeing the new crate cummins V6 stuffed into a 3rd Gen. The magazines had put it in a few different vehicles and the outcome was always awesome.

Nice work with the video editing, that guy made the LSX swap in his Tacoma look really easy...
- Chopped the radiator support, there goes not having to cut anything
- 2WD so no worries about oil pan clearance or having to mount a transfer case to to that 4L80 transmission, or the electrical stuff related to the 4WD system
- let's make things more complicated and expensive (AN plumbing is not cheap or that fun to work with) by mounting an undersized trans cooler underneath because there obviously isn't any space in front of the radiator for a properly sized one
- did he even plumb the AC and power steering?

Well bummer, just read Tyler James Inc build thread and he said after he put the 5spd manual in his 2002 he felt the auto had more zip. I would have expected the opposite. Also looks like my 2002 with VSC and TBW makes things a bit more complex in terms of ECU and wiring options with dash lights remaining on. I can't have that.

I've had two 5spd 3.4L Tacomas over the years, a 1997 and a 2000 TRD but it's been so long I can't remember how they drove compared to the auto in the 4Runner.

Bummer, without engine upgrade options easily available I'd hoped this might be something.

Maybe what I have is about the best you can do.

Gonna watch the V8 swap vids over the next couple weeks at the gym, but if he bypassed power steering, ac, etc that's no bueno.
