4.7 Rebuild Options. I need more grunt.

[EricUT]

Hi, just wrote a super long post to explain why I want to do this, but realized it's easier to just cut to the chase. I know this is an age old question and I have taken the time to read a ton of old posts, but curious what the current thoughts are. I'm wanting to get a little more grunt out of my 4.7L to pull a smallish travel trailer, maybe like 4500# max loaded. I know it can do it, but we live in a very mountainous area and the 230hp 4.7 is going to make for some long days.

Anyway, I'm interested in maybe doing a stroker build...has anyone on the board done that? And are there any kits available, or is it a ground crank and mix/match rod deal? Any go-to machine shops specializing in it?

What else have guys done for these things? Are any of you running a turbo or supercharger? How about outright swaps? I know the consensus has been that it's more trouble than it's worth over the years, but seems like surely someone has done a 5.7 transplant or a TD by now?

Anyway, I'm definitely serious about this and really interested in what's been done. I'm not looking for anything super high performance, even a 30% gain would be a game changer

Thanks in advance...and yes, I know the smart and more affordable thing would be to just get another truck. I don't wanna

TRD supercharger gets you to a net of 400 hp, but for the price it would probably be cheaper to swap in a different engine.

Why not just regear your diffs instead?

All the threads and talks I’ve seen, doing a different engine swap is going to be the most expensive option by FAR. We discussed the 200 Series 5.7 and doing an LS swap and you’re easily looking at $20k+ if not $30k+. So not worth it at all, and then you’d still have to do something about putting in a stronger front diff to hold that power reliably.

I wonder if you could get an imported 4.2L turbodiesel from Japan that came out of 100-series LC. Like this one:


Unfortunately you cannot import a 1998 LC to the US yet (25 year old rule vs 15 year old rule in Canada), but you can get the motor, trans (manual if you are lucky to find one), ECU, exhaust, etc.
That way it will be stock, practically a direct bolt on and you don't have to customize exhaust, etc. One condition though, it may not pass smog testing, so it would be an off road use only unless you live in an area that does not require testing. Call this guy, Mr. Martin and ask what your option are: Toyota Diesel Hilux Trucks, Land Cruisers and Parts.

People are taking these engines to 300k+ miles, think you're still a few years off from seeing swaps. Even then, folks will go to a 200 first.

I didn’t say anything about a Toyota 5.7 swap. There’s a reason(s) nobody has swapped one into a 100 (that I’m aware of). Your options are 1) 2uz-Fe supercharger 2) non-Toyota engine swap, or 3) sell your 100 and buy a 200 series.

I will say that if you’re not doing the work yourself (given the $20-30k you threw out, I assume you’re paying someone), then it’s simply not cost effective for anything other than buying a 200 series.

I've looked at the options and I think my plan is to rebuild my cylinder heads and install upgraded cams. There are a couple options I'm looking heavily at the Kelford 208-B. Already collecting parts. Turbo and sc options are available but I think this will be my path. I will also tig weld my air injection ports closed and install Australian long tube headers. Hoping for 80hp or more gain once tuned.

Even if you were to build the motor, how would you handle engine management? A proper tune would probably net the same power gains.

To be honest though the biggest reason why many people like these rigs is the reliability aspect, so a built motor accomplishes the opposite of one of the shining qualities of a landcruiser. If anything I would say regear to better use the power you’re already making.

200 all day if you're looking for power. Brakes are better too. My other vehicle is a supercharged 100...

Agreed. A 200 will solve all of your problems and is a much better tow vehicle too.

And after seeing them in action at Moab, they are just as if not more capable than a 100 off road.

Are you having your LS plated in gold?

A L83 is 1500-2k all day. Pick your transmission for 1500-2k.

This will happen to my truck eventually. I'd guess it comes in under 8k.

Do it.....

Look up the thread where this was discussed by people that did the swap.... I said what you’re saying but apparently there’s a lot more to it than just buying a junkyard engine and tranny...

I’m not an engine expert by any means but I’ve been helping my brother build his drag cR for the last 15+ years. We’ve lost count how much money is invested at this point. On paper yes, but a 2JZGTE motor for a simple swap into an SC300.... next thing you know you’ve got over $100k and counting into the build. Not saying it cannot be done for less but if you want quality you’re gonna pay for it even if you have a lift, shop access and tools and can do your own labor like we did.

I believe it.

I've been part of numerous engine swaps - one that was one of the first in the world of its kind so it had very little documentation (s54 into an e30).

If theres a bunch of customization around the transmission, thats the hardest part, IME. 80 series guys do this swap all the time. Theres plenty of info for anyone to lean on. Its not straight forward, but if you're doing it yourself it wont bankrupt you.

OP: Start reading - 8x Series V8 Swaps

SLEE has a turbo kit. Honestly, my DT cat back made my 98 go up passes easier. could do headers and cat back and gears and might get you where you want. Return on $ is probably better suited in a 200 series than trying ot get more power in the 100

I wonder if there are any Saudi shops that build the 2UZ,

Edit: seems slee doesnt offer the turbo per their website any more. I htink Jason @ Trailtailor is sourcing together a turbo kit.

Ever considered staying in a hotel so you don't have to bother with a trailer at all? Safer, more comfortable, most have pools, no trailer to store 11 months per year, easier to drive without trailer, no need for more power, and probably far cheaper too.

Or just buy a tent and sleep in the dirt. Some of us revel in peasantry

Getting off topic but I remember reading about an S54 powered E30 and thought that was hands down the ultimate M3. I think even the instrument cluster was swapped in too and everything looked real clean.

Hah, thanks for all the responses so far. My first post that I deleted was explaining that yes, I know rational thing to do is get another truck, yadayadayada...so got a kick out of some of those comments. I knew I was setting myself up for a lot of opinion on why I shouldn't try. Particularly amused by "ever think of staying in hotels so you don't need a trailer?" I have kids, this is a camping/adventure rig.

Anyway, the inevitable, unsolicited advice on my life choices aside , there's some good food for thought in those comments too. Supercharger or turbo is obviously doable, I'll keep searching for more info on that. If anyone has any first hand experience I'd love to bend your ear. And it can't be out of the question to stroke and punch these things to like a 5.2 either, so if anyone has first hand experience with that, again I'd love to talk about how you went about it.

Roosevelt, I've done quite a few transplants too, mostly stuffing big blocks in old hot rods which is obviously easier than this, but these things can be done!

Anyway, thanks again for the ideas so far...yes I know it doesn't make sense to a lot of people, but stuff like this floats my boat. I don't want a 200, or another pickup, I want to build a 100 that can do what I want it to do, mostly because I find things like that fun

We kept the stock cluster. It's a fun little car that's now a track car. TBH I think the e36 is a big enough step up in suspension design / chassis I'd go with that, but it is isn't my car, haha.

But just like some of the comments in this thread recommended to the OP to get a 200, there's always something newer or better, but we love what we love. I know I love my 100!

Kurt @CruiserOutfitters might be a good resource to start with. Hes built desert race 100’s/200’s , Baja and Dakar (@Canguroracing). If theres a viable path to squeezing more ponies out of a 2uzfe, he’d prob know about the best way to do it.

Another resource you might try is Jowett Performance. Jowett Performance
