Hey my memory is working

Yeah, the 06 cummins will wastegate around 30-32 psi, then hold 25+ steady... thats a TON of boost...

Bumpin' Yota

The 6.0L powerstrokes from '03 to '07 all will hold 30psi but they dont have wastegates.....


ps - Any diesel I own will smoke like a beast from the gates of hell....

my buddy did this swap in a 85 toyota 2002 24 valve/6speed/205. it was a hack job but he did it to say he did. radiator in the bed cut out the core support and had to move the front of the frame out like 10". had to set the motor alittle bit crooked so everything would clear. it was a very fast truck.

I know that the motor in my truck is not a Cummins but it is a turbo diesel 4 cyl. I have my Toyota 1kz-te turbo diesel running in my truck now and I will more than likely have it on the road sometime this week. My dad has a completely stock 91 xtra cab V6 5 speed with 4.56 gears and it is in perfect shape. I have driven it quite a few times and know what it can do and I will let you guys know how the diesel compares to the V6. I have heard 2 hp numbers for this motor. One is 165 hp and the other is 130 and both are at 3000RPM. But the torque numbers I have heard are all the same and it is 230 lbft at 1800RPM. It should move along quite nicely and should sip fuel very sparingly. Here is a link to the motor in the truck running. I just need to get the rest of the lights and stuff done on it and bolt the fenders back on and stuff. http://www.youtube.com/watch?v=zMQ2QX0QRD4

Well, I can tell you that the HP is most likely the 130 one.
The HP that the engine is producing at 1800 RPM (where it's torque is 230) is 78 HP.

So if the engine were producing 165 HP at 3000 rpm, it would be producing 288 lb-ft of torque at 3000 RPM, which is higher than the 230 that you've already mentioned.

If the engine is producing 130 HP at 3000 rpm, it would be producing 227 lb-ft or torque at 3000 rpm, which is more in line with the 230 max torque at 1800 rpm that you've mentioned.
Actually I suspect that the HP at 3000 rpm is somewhat less 130 HP.

Those are just the numbers I have found many places. How did you go about figuring all that stuff out without a dyno to get the numbers? The hp numbers were in some metric units. I think kw so I converted them. And the torque was in Nm. But even if the hp is 130 and torque is 230 it should still move along quite nicely. These motors also respond quite well to intercoolers and computer chips. After I've got this thing on the road I would be interested to put it on a chassis dyno and figure out exactly what it is to be sure.

They removed the wastegates on the 6.0's??

EDIT: Duh forgot its a EVGT turbo, doesn't use a wastegate.... brainfart.

I havent seen the boost on the cummins yet with a load, but my dad says it usually is between 25-30, sometimes a little higher when pulling rocky mtn hills towing 10K, thats also limiting fuel to 1200*... so I would guess more boost is possible (depends on wastegate) but at the price to too high of an EGT.

FredTJ

Why would I need a dyno ?
You can't measure HP on a dyno.
HP (on engines) isn't ever measured it's computed.

A couple of things.

- Dyno's can't and don't measure HP.

- HP is virtually never measured it's computed from torque (on engines)

- Dyno's measure torque.

HP and torque are DIRECTLY related. On ANY engine the HP and torque is equal at 5252 rpm.

If you know one (either HP or torque, you can easily get the other)

HP = (Torque * rpm) / 5252

Torque = (HP * 5252) / rpm

On ANY engine.

Simply no magic to it at all.

Lastly you can't "feel" HP in an engine. When someone does a mod and says "wow, it feels like 13 more HP), they are simply clueless.
You feel torque, not HP..


Just for comparison with that diesel, the "lowly" Prius's electric motor (which has a hell of a flat torque "curve", as do all electric motors) puts out 295 lb-ft of torque from 1 ~ 1200 rpm.

too bad that electric motor's torque stops at 1200rpm rendering it completely useless beyond 10 miles per hour....cuz after 1200rpm the BEASTLY gas engine with its 82ft lbs of tq takes over.

FredTJ

Just stay tuned.
Lot's of power coming in the next couple of years or so.
Hybrids, running mostly electric (so called "extreme hybrids") will be here before you can blink and the electric motors will really come into their realm.

Regardless, currently the Prius will smoke a 3.0 off the line, easily.
Ask me how I know.

Thanks for telling me about that. Never knew that. I just know I finally got to drive the thing today and its a big jump over the old 22R and also over the 3vze. Sure pulls good down low. Really good. I should have it on the road this week and I'll say what I really think of it then. But for now I am impressed.

Anubiscougar

heard plans of toyota making a hybrid tundra w/ a v8. i think it'd be interesting... as well as a diesel & duallie... duno the truth to those claims. ohh, i'll tell you one thing, the v6 hybrid hilanders = holllllly crap, bawlsy. :-P.. for that type of vehicle, lol

So back to the diesel at hand... cummins in a yota possible or no? So far i've seen not worth it, frame can't handle it, and... too heavy.

Against that(my thoughts here) is, it's worth it for the oo's and aahh's you'd get and self approval, frame, if you have a welder, you should be able to take care of that(who cares what engine it is, i've not heard someone complain about hurting the frame w/ 400-500 tq from a sbc 350 in a yota, power is power), and weight... wow, use 6" springs on the front, and 4-5 on the rear.. rofl.

I'm not talking about towing here, just talking about an offroad truck, & every day truck.

so... yay or nay? Cuz i've been toying w/ the idea myself.. I could pickup an old salvage cummins truck for about the same as it'd cost me to properly put a sbc in my truck... and then i'd have solid axles out of it too! haha!

thefallman

we aint talking dodge cummins here we are talking Frito-Lay cummins. i dont think you want frito-lay/ups truck axles under a toyota. for one thing they arent 4x4.

the differnce is the 4bt is a 4cyl where the dodge/chysler is a 6

camo31_10.50

i have done alot of research on the 4BT cummins....VERY impressive diesel 4cyl.....with just a few tweeks...(just turning a couple screws)...u can get over 160 hp...and over 400lb ft of torque now dont get me wrong...you wont get the same MPG's out of a cummins 4BT that u would out of a toyota diesel.....but the cummins has more power.....WAYYYYY more power...my dad and i are thinking of doing this swap too...(we make biodiesel...so diesel is the way to go for us)...a place called Proffitscruisers does 4BT swaps into land cruisers...im not sure if they have ever done one into a pickup....if you want to know any info...go to 4btswaps.com LOADS OF INFO THERE!!!...i got quoted $1000 to $2200 for the 4BT...(not rebuilt or anything)...and then about $60/hr labor.....(which it would come out to be about $3500 labor...IF i was to take everything else out...like...the 20r the tranny and t-case)....and that is insane..WOW high prices....but now if it were a rebuilt cummins...then i would most likely go for it....but none of the diesels that this guy had for sale had over 100,000 miles on them....most didnt even have 50,000.....

I did a Cummins swap with my 4Runner...



Well, sort of

lol Hey, go talk with Toyota and ask them why they didn't import a usable Diesel here! (The 2L just doesn't cut it)

I would love even a Diesel landcruiser, but noooooo they droppped the ball there. So thats fine, my Cummins will work juuuust fine!

aww man, yours is bigger! And no VP44! AND a 6 speed!

Lucky.

last i heard the 4bts were getting in the neighborhood of 30 plus to the gallon how do the toyota diesels compare
