Ok, i have been lurking here for some time now... seen alot of posts about motor swaps and whatnot... here's my question. What, if any, other small dohc motors will bolt to our tranny's?? I know something does. There is a guy at my local track running mid 12's on an stock auto. Has new axles of course and a rebuilt torque convertor. Anyways, he has a swap and is running the quad throtle body 20v silvertop 4age head but not sure on what block. Also running aprox 32 lbs. of boost on a the built motor. Anyone know for a fact what blocks will mate up with our tranny? The 4age 20v motors seem like a perfect swap, being how the mr2 is almost the same width as our boxes and the blacktop wopuld be around 160 whp. That is more than the 1nz could pump out even with max boost. Just an idea and want to see what everyone else thinks. Also, if anyone has the manual tranny code that would be helpful to see what other jdm cars have it. Thanks --Eric

so judging from the lack of replies.... there isn't anyone who is sure what blocks mate up with our trannys?

then u said hes running 32lbs of boost on a built motor. no one wants to reply with a story like this.

First of all, :rofl: .

Second of all, our 1NZ block can infact put out 160hp. You seem to have no idea what you are talking about. 32psi my ___. 32psi will blow any motor that is able to fit in the tiny compartment of the xb's.. Built or not. One of the larger motors that can fit in ours is the 1zz, and even then you still have problems with fitment. If you managed to fit a 1zz, theres no way in hell you are pulling 32psi. Do some homework before you come in here asking about this stuff. Honestly..

The Yaris T-sport motor should be a direct bolt on since it is just a turbo version of the 1NZ-FE with 150 hp.

150 Flywheel, which equals about 125 ATW, you could get the same with the Blitz S/C,

Well, i was just asking a question. 32 lbs. of boost is nothing really. There are guys out there full race running upwards of close to 50 lbs. If you don't know what you are talking about, please don't post negative comments. I was just asking a simple question. I am new to the toyota scene but not new to imports. I used to have a sleeved and stoked 2L honda b series that I had pushed up to almost 40 lbs. And as far as the small enginge bay, all you need is a lovfab sidewinder manifold and you cna put the biggest badest turbo you want in there. I am not trying to prove anyone wrong, just please don't put me down and tell me i am telling a wild story when you yourself don't know what you are talking about. Thanks -Eric

Thing is Tweeter, the 1NZFE engine doesn't handly well to high boost unlike other engines. Going over 8psi daily is like driving a ticking time bomb if you don't have built internals.

So don't take it to heart when some of the members laugh at your questions. It's just that so many people who come to this board asking the same thing over and over while the answer is always the same.

You should check out this thread if you want to know more about FI for our engines and the results in the end.

32psi is a hell of a lot of psi, sorry to tell you. The "biggest" turbo means nothing when you will be running a blown motor. As i've said, built or not, no motor that can safely fit in the current engine bay cannot run 32psi. If 30+ psi was nothing, people wouldn't make huge deals about it. Example: Skyline running 34psi, completely built will be on the covers of magizines for a while, talked about even longer.
Theres no point in arguing with someone like you. At all. Good luck.

I totally agree that the 1nz isn't a motor that will be making alot of power. I would never try to boost it over 12 or so even built. The guy I know of is running a 4age 20v head but not sure what block. I know it isn't a 1nz. Like I said, i have been lurking here for months and read everything I could but so far nobody that i know of has for sure figured out what motors will mate to our trannys. I know you can change the bell housing but then you have to worry about the input shaft meshing. Anyways, I was just asking a straight forward question. I am sorry if you don't know what you are talking about when it comes to boosted motors. I speak from experience, not magazines. How do you think pro street cars are making 2200+ horsepower? I can tell you they are running ALOT more then 32 lbs. I am not however saying I would run that much on a 1nz, i am saying it can be done and is everyday at the tracks. For the street it would be pointless, and if you get 10000 miles from a motor running that high of boost even only at the track you are doing well. Thanks to all the are posting serious replies and not just running there mouths. Thanks again, Eric

:rofl:
Amazing.

Toyota Engines in the Same Family (1NZ, 2NZ, 3NZ) will all have Transmissions that will interchange. Using one from a different family I.E. 1JZ, 4E, ect. will not bolt up and you will need a mounting plate.

As for the rest of it, I've said it before "The ignorant will never admit to thier ignorance, so arguing is a waste of time."

Now wouldn't a built 1.3l (factory turbo) motor be able to hold 30+ psi if built to hold it?

I know that a 3sgte built up can hold it, and yes it doesn't fit in our engine bays.

If you have the money to build the motor, i think it'll happen. There are a lot of motors out there that can hold 30psi...most of them are 2jz's that I have seen. And they lower the boost for daily driving of course.

a lot of tuners also program the boost to adjust to the rpm points so they can run max psi at all rpm levels safely. I had this set up on my 300Z....However even being careful at I once put 2 pistons through the block at 24psi.LOL...I had to re-do the engine and sleeved and had no more problems

if he put a turbo diesel in it he could run 50 lbs, only engines I know of that can take more than 30 lbs without 10's of thousands of dollars of work are diesels, and there are some big 3500 series dually trucks running 11's and better pushing upwards of 75 lbs of boost, but they also spew chimneys of black smoke, use propane injection etc.


on a Street/Strip car anything more than 15-20 lbs is INSANE, and on a non turbo engine from the factory most yuo can run is 8 lbs, or 10 lbs if you intercool it, more than that and you are really pushing it.


Of course a ricer mentality could let you believe that you could stick a T88 turbo on a toyota echo motor and run 10's with nothing more than a special manifold to make it fit.....

I never said it was a stock motor. I said stock auto tranny with a built torque converter. The motor is a swap of some sort and I know he has some money into it as well. I have a friend who is also friends with him so I am trying to make buddies with him to see what block it is. And as for a ricer... sorry, I am far from a ricer. So go read some more magazines and post away. Thanks once again to all with serious replies. I will keep you updated on what info i find out. Thanks, Eric
