pondering the idea of a v8 3rd gen swap

[shakey1378]

considering motors dont last forever, i wonder if anyone has installed the 4.7 iforce v8 in a 96 to 02 4runner. id like to research this my truck turned 70k and im sure theres a lot of life left in it, im just a little power hungry thats all.

4.7L swap

Swapping a v8 in a 3rd gen 4Runner would cost major $$$$$.
First off I think the transmission bolt patterns are different, so you would need to change the tranny and the transfer case and maybe need custom drive shafts. Next custom made motor mounts and exhaust. Also the complete wiring harness and computer which may also include the ABS control module for the traction control and the VSC if eqipped. The master cylinder for the brakes may also need to be swapped. An electric cooling fan should be added in front of the rad for extra clearance and the fan of the V8 removed. This is probably just the tip of the iceburg. If you are really wanting to do this you would probably need a wreck just to get all the parts you need.

Just get a supercharger...it would be alot cheaper and probably much more reliable

I have heard of a few Chevy & Ford V8 swaps, but no Toyota V8 as of yet. I suspect buying a Toyo engine used, new or re-built might get a tad expensive. So putting a V8 in can be done.

imo, if putting in a v8 into a 3rd gen costs more than 40% of a new v8 4runner, your better off buying a new one.

ie: avg cost of a 04 v8 4runner is around 30k-35k, so your cutoff would be around 12k-14k.

the engine/electronics/transmission is probably gonna be your biggest money items.

this is just off the wall speculation.

Does it even fit??? The 3.4L V6 is already tight in my 4runner's engine bay.

From what I've read swapping Toyota and Lexus V-8's into trucks and 4-runners is common in AU and NZ. Here is one site http://geocities.com/deonsv8hilux/ . If it will fit a 2nd gen it will fit a 3rd as well. Will have the exact same bolt pattern (3.0-3.4). All you need is a wrecked Lexus, Tundra, Land Cruser etc. with a V-8.
The link above is one of 3 I've seen on this swap. All were from AU or NZ though. Remember also an inline 4 cyl is close to the same length as a V-8. I want to do the 7M-GTE swap. Now that engine is definetely longer than a v-8.

It could work, if you familiar with Nissan Altimas someone took the 3.5L V6 from a 3rd Gen Altima and swapped it into a 1st Gen Altima

But thats fwd.

Price of V8 swap > price of new 3.4L V6 + Supercharger which IMO > 4.7L V8.

:yesyes:

Interesting opinion, what do you guys think of this 6 years later??

Ive been contemplating a v8 swap, either Chevy 4.3, 1uz, or getting a remanned v6 supercharged 3.4...

what do you think costs would be on each and hp gains??

Good question I'm curious as well...
Duhockey you are on a thread resurrection rampage! lol

 

[steezemcqueen]

best bang for the buck would be the supercharger. the 1uz would be cooler and probably more power. but it would be more expensive. if you put the chevy motor in your runner, we will no longer be friends. you have been warned

Wow, talk about bringing a thread back from the dead!

FWIW, if I still had my 3rd gen and was looking to do an engine swap, I'd probably just do a 4.0L V6 swap. The power increase would still be very good and the swap would probably be a bit easier to pull off.

:lmao:

so true!

 

[Duhockey]

everyone says it will be cheaper to do the supercharger, how about $$ per hp evals here.

how much money would it realistically cost to do a v8 swap and then how much HP gain, vs. how much for a remanned 3.4 TRD supercharged engine and how much hp gained??

you can also include the 4.0 v6... Im game.

If you want to add more power per dollar, you need to go turbo route. The factory ecm is adaptable for a supercharger then a turbo mod should be the same to the ecm.

You can even utilize the hood scoop for an intercooler.

If you can cut and weld, you should be able to do a retrofit quite painlessly.

Mind you, a turbo takes wasted energy and converts it to power. A SC takes energy to make power.

Pop a Chevy 350 in it, then supercharge it, i'll still be your friend if you do.

Doing a 4.7l v8 swap into our gen 4Runner is out of the question imho,
Looking at the wiring diagrams alone for lets say an 02' compared to an 03' is different enough.
Then you also have to account for the body electicals that now get read by the Main ECU, so if there is an issue weather it be an engine issue, the check engine light illuminates.

Trying to get around all that BS right there is just not worth the time, let alone having to make mew motor mounts, get rid of the mechanical fan for electric, new driveshafts and trand mount because you know you will have to move those back to acomodate the room for the bigger V8.

The 1UZ is a better option when it comes to doing a v8 swap.
But the same power can roughly be achived from rebuilding a 3.4, mounting a supercharger, and tuning it just right.

The turbo idea is a great idea, I have been thinking if I wanted more power I would go that route, due to the fact that I will be running a York air compressor soon which takes place of where the supercharger pulley would go :-(
