My 70 Duster build

-
not sure to be exact on HP. i figure 275 hp give or take. it really depends on where i limit the cyl head work and turbo upgrades. 300+ hp is not hard to get. i'd say not bad for a 2.8 liter. i could see your nausea if it were a ford or chevy. finally a purist has emerged from the bunch. lol

Oh heck yeah, guilty as charged. I absolutely hate Toyota, Nissan, etc. But that could be a very long discussion, and ruin this fun thread.


I just don't get it though, why take out a motor, that has easily 450 hp potential, and do all that work, for one that is 2/3 of it?

Kicks? Gas mileage?
 
I appreciate the work involved and getting your family involved in the project....cudos to you.
However, why would you take a step back on horsepower to 275-300 when a slightly warmed over 360 would get you there a lot easier?
Dare to be different? I like that and it's a cool looking engine and all....but why really?????
It's a cool swap though.
Interesting.......
I wouldn't attempt it though. To me it's backsliding.
What do you expect it to run? 15's at best is my estimate.
 
It is an awesome project you got there, being a toyota race car owner for long time, my only question is, why that old M series engine and not a 2JZ newer more powerfull and reliable one? not expencive if you use the lexus GE non turbo unit and converted to turbo, i have seen Factory internal 2JZGE converted to turbo in the 600+ WHP range with good reliability for years and years, ohh and a r154 with the marlin crawler internals can stand 1100 WHP on a 2800 lbs. car, i used to have a 1100+ whp 2JZ 79 Celica drag car and trust me the only way to go is with the 2JZ!
 
I have to agree,...cool car. Shoulda based the drivetrain off a NA 2JZ 5/6 speed...pretty affordable JDM engines...tons of potential.

Easily support 600-800hp.

Good luck

well i have to make a fresh air intake on the pass side and also need to feed air to a top mounted intercooler mounted above the drivers inner fenderwell under the hood. the scoops will be made out of aluminum measuring 3.5" x 12" one on the pass side and one on the drivers. there will be a rectangle duct 4' x 6" going up through the fenderwells from the scoops for feed air for both intercooler and intake.

I seen a GLH with a top mounted intercooler and had it sticking through a 6 Pack Scoop.That would look cool if you had an extra hood.Ive been playing around with the idea of putting a more modern engine in my Duster,like a small block out of a Dakota with fuel injection,but beyond my budget or capabilities.I cant wait to see this done=D>
 
Are you not going with the 2JZ? I though you just had this one in their for the mock-up and were going with the 2JZ for the actual engine. They have WAY more power potential! I might be confused though.

Also If you are going to do the scoop. I would do two. One for the inter-cooler, one for the Intake. But I Like symmetry.
 
here is the plan, i have this truck its an 82 Toyota show truck. built by the Legendary Dick Dean and his son Keith. this truck was very fast. at that time my duster ran 13.8's and i got smoked, like two cars per gear it was shameful. this truck was approx 2800 lbs. the trans grenaded so this truck has been sitting for a good 16 years. sadly the rodents and weather really wasted the truck. two years ago i started to clean up this truck with the hope to make it run again and street worthy. i bought a house that only has a 3 car garage and a small plot of land. i had to take the truck back to my bros. to let it sit till i have time and space for it. i want to restore it to the best of my abilities when the time comes. with that said. i am tired of the shake rattle and thirstiness of a V8. the idea of putting 70 bux into the tank and being on E after a weekend is not a wise thing for my lifestyle. i have my single income with 5 kids, wife and Granny in the house. this engine and trans will cost me next to nothing. so yes 2JZ is a wonderful idea. even a 7MGTE makes more power than a 5M. like i said before. i am not interested in a race car. been there done that. once the 5M is running good in the duster. later down road when i start restoring the SupraTruck, i can pull the engine and trans from the Duster and place it back into the Supratruck. then at that point maybe then i could spare the $4000-$5000 to do the 2JZ swap. after you pay $2300 for the motor and ecu. $1500 for the trans and all the other things that will be required to make it run its not a cheap as we all would like to think.... so when i master the 5MGTE and if feel i need more power, i would be ready for the 2JZ swap.. as for the scoops the plan was making one for each side. it would look like crap if only one scoop.
 
No reason to expect a lynching, it's your car, build it your way. Not everyone will agree with your choices, but they won't be the ones driving it. Anybody who has a problem with it doesn't have to read this thread.
I'm interested in seeing how you approach the build and the solutions you come up with to the problems that arise.
Good Luck!
 
2JZGE is about 5 to 600 all day here hell i got a long block here at home i am willing to sell for 300 to you so you can start doing some study on them,

by the way a litlle knowledge dont do any harm so here it is some facts;

the M series toyota engines where desingned as a N/A engine from the get go and converted later to turbo aplication later it got many weak points that are cured and perfected on the 2JZ.

The 2JZ engine was designed as a turbo engine from the get go and then converted to N/A later for the USA MARKET LEXUS! so thats why with just a (thicker) turbo head gasket they can handle all that power in stock trim and i mean stock internals no fancy pistons or rods, the GE head outflow the GTE head this is necesary to achive the 220+ N/A horsepower they got, and when converted to turbo they are beasts,
you can hook up a GMTH400 trany behind them easylly or a Powerglide, i have seen many with torqeflites with good results, or any borg warner t5 or anything you can hook up to a chevy, farlly easy with the gm adapter plate and some fabrication.

A good advise and my opinion is, dont spend twice do it once and do it right ;) good luck my friend!

Anything i can help you let me know i am a toyota expert and have built many 1000+ whp 2JZ many 600+ 3TC turbos, and many other ones!
 
a friend just picked up a 2jz twin turbo, aluminum pulleys and ecu he spent 2300 or 2500. there is just no way for me right now. then we are taking the car into the performance level where i don't really want it. good info though.

Demon1515 since you are familiar with the turbos and these engines. this Spearco Turbo setup i have boosts 14 psi. what would you think this thing makes for HP?
 
In a 5M at 14 PSI i dont think it will be more than 220 tops @ the wheel but with the size of the turbo it will be torqey you need more turbo more boost and more fuel, i bet a good 74mm t4 turbo with an A/R of .84 on the hot side a set of 6 750cc injectors and a stand alone on a good tune with 25 PSI it will do about 450 at the wheel but then the lubrication on the engine will be an issue, you need to replace the banjo tube from the oil pump pick up to the block with a braded line with a an fitting in -10 size if my memory still good to prevent the cavitation from the poor transition of oil in that part of the oiling system!

got ya, on the GE. i will do some reading up on that. the ct26 turbo off the 7M i have in the pics. how is that compared to the Spearco?
Click to expand...
I am a litlle confused here, as far as i know or remember i have never see a Spearco Turbo before, the most common turbos i know about are; IHI, HKS (wich is made by some other company) Air Reaserch, Garrett, Turbonetics, Presision, Holeset, Switzer and Borg Warner.

But to compare any turbo to the CT26 by toyota i need to know specs, by the way you wont be able to generate more than 200 WHP with the CT26, it is just too small in the compressor inducer, but that does not take away that it is a tough turbo, very reliable one!
 
Well the latest is I haven't done much with it. I am still waiting for my brackets to be laser cut and the aluminum air scoops to be welded. Neither have been done. I guess when you are waiting for favors. Paying customers are first in line. looks like I will be shaking Them down for my parts so I can start working on this again.
though i did find replacements for the "340" hood scoop emblems!!!! celica/Supra Dragons for those who don't know..... it looks like i have 2 "340"scoop emblems for sale now....

u should put updated dodge engine in this not a japense engine in.u are so ruining this car.this car is old its supposed to have old stuff on it.u should just keep your 360 in it and rebuild it.
 
this is an original 198/6 car. it has a salvaged title. this engine swap is all about reliability and efficiency. 23 years of having a V8, i want something different. all of my parts have gone to other people to make their cars better. its win win if you ask me.

The great thing about this country and this hobby is that each of us has the freedom to things our own way and to build the car that we want, not just what's popular. While the idea of putting a Japanese engine in a Duster may not be to your liking, if you take the time to read and follow this thread, you might find some inovative ideas and answers to problems that may arise in your own build. If, on the other hand, you don't like this build, don't read the thread.

i almost take offnse at this statement. and its not evn my car. Just because the equipment was not made by a manufacturer with a headquarters that is nominally on our shores does not make it "bad" or "ruining". also, you have contradicted yourself with your post. putting an updated doge engine is not having old stuff on it.

the process of taking what mother mopar gave us in the early 60's(when the a-body archetecture was designed, around 50 years ago) and updating and upgrading it to combat todays road conditions and drivers is what this thing is all about to some of us. jsut because we use technology from other manufacturers and eras does not mean that we are ruiing a car. it means that we are working to make our cars more usable, more enjoyable, and safer.

by looking at this swap, he is doing it in a way that the car could be put back to stock. how is that different from a modern hemi swap? (which, by the way, was developed under diamler, a german company). or for that matter, im using nissan 300ZX rear disc brakes on my 70. does that mean im ruining a car? what about mini starters, which are manufactured and designed by nippindenso and sold to chrysler?

im sorry to rant, but the old way of thinking on some of this stuff irks me. in america, at least the america i grew up in, innovation, improvement, and doing the best you can with what youve got was to be embraced, not looked down upon.


back to the origonal thread, this is going to be a neat swap. id take a look at incorperating the intercooler scoops into a front air dam to make them blens a little better. think something from the modern bonniville cars. just extend the rockers to match, and add a rear diffuser. complete the package. you obviuosly have the fab skills to pull it off.
