Well, I am gonna build a turbo kit for the XB and I wanted to get some imput on what u guys think the little 1.3 liter beast can handle?

I was thinking to keep it safe just go with 5-7psi.

Does anyone know what the TRD supercharger boosts?

Also does anyone know were they sell forged internals for these motors?

Oh! whats the engine code on one of these? (u know like 2jzgte, 4age, 3sgte)

 

[ScottyTuned]

its a 1.5 liter first of all, second of all they suck at holding boost (even though youll be safe at 5-7), and you wont be able to rock a TRD supercharger unless you have the JDM motor/ECU. Check out ZPIracing for internals. its a 1nzfe.

Actually the JDM offering is a turbocharger, and it is only available over there for the 1.3 liter version of the motor.

As Scion Scotty said, forged internals are available. Just contact any of the major manufacturers. Some will be less than others as they have already done pistons for the 1NZ-FE. ZPI is far from the only source for forged internals.

does anyone know what the average HP one of these motors can put out?

Im more of a nissan guy and i know a few toyota motors. I was thinking a 3ste swap would be bad ass but thats alot of work. IDK if someones done it allready or what but it would be cool.

Well ill look into it. If I boost the stock motor im sure I can get an AFC and tune air fuel and probably upgrade to like a 370cc injector. Im sure with the right fuel compinsation for the 5-7 psi it would run pretty stong.

We will see I guess.

3sgte is a HUGE motor. way too large for this engine compartment without TONS of work.

1zz or 2zz motorswap should be easy enough long as you have the money.

I know of one turbo xB that puts down 143 hp and that it needed some minor tweaking. But, due to the overall design of the engine, it will not last as others have stated even if you do stay within 5-7 psi.

If you really want FI, your best bet is a SC from GReddy or Blitz.

 

[scvscions]

I heard that there's some gains to be had with a return line fuel system after turbo install. You're going to have to drop compression and o ring the motor using a copper head gasket and then you can boost 10 to 15 max. A lot of programming is going to have to go into the fuel management with the proper injectors to get it from leaning out and going boom. And the rods and pistons before coating are expensive.

 

[Dub40sx]

well ****, basically these motors are junk then.

I guess im just gonna have to do some small stuff for now like an Intake, Exhaust. Some small stuff to just add that LITTLE power add.

Man i wish these stock motors could take more abuse.

How much hp are you looking to run? You can run these motors daily boosted with 7.5psi on them and if taken care of and not beat on to terribly hard, you shouldnt run into any major problems. If you want to run more boost than that daily, then build the engine, do what you can for the tranny , get better motor mounts and push the envelope. I think with the proper work you could run these motors atleast at the 200whp range maybe more.

 

[ctruss]

I think people are just scared to push these little motors. I have never in my life seen a motor that couldn't handle 8-10 psi of boost everyday.

My friend took a Ford Escort, a car everyone told him couldn't handle boost and turned it into a car so powerful he can't find anyone that makes transmissions strong enough to handle what the motor can put out. He ran a low 13 sec 1/4 after he blew the differential out of it halfway down the track and coasted the rest of the way.

Boost can be done on these engines and I honestly believe 180 whp should be no problem and can still be daily driven. You just have to choose the right injectors, spend some time on the dyno with tuning, and you are set.

 

[squirrel]

Its more of the design of the engine and the angle of the connecting rods and crankshaft.

The return line, injectors, and good programing is half the battle.

A good set of rods and pistons will cost $1,600 minimally.

Remember, the the engine was designed to be economical, and its not bullet proof like other engines in the Toyota line.

 

[BoomBox]

^^ Many had said this when the Civic became the hot car to modify.

Just give it time, parts will come out, prices will drop, we'll see some crazy engine modding for the 1nz-fe, which means xA and xB owners will rejoice!

Why do you think the car is only $14.5k???

Of course the engine is junk, most import cars have pretty crappy engines.

Hence the reason you have no problem pulling them out and tossing them for a better one.

That's the reason that RX-7 owners pull out the rotoray after it craps out and put a LS1/2/6 in their.

Also the same reason that even BMW owners swap out to the LS1/2/6. They are small, cheap, and they are lightweigh.

I want someone to do a LS4 FWD engine swap on their xB .

That is a person you can bow down to!!!

 

[killerxromances]

I love how everyone still puts down the 1nzfe motor as "no power can be made". Its not a power house, agree'd. But majority of you haven't pushed the motor at all. And you go by what others say that are smart yes, but i can only think of 3-4 owners that have actually pushed the motor hard. All of which are rarely on, and yet all this mis-information is being passed down.

Small motor yes. Small power yes. Light car yes. Do you need 350whp+ to go fast? No.

Oh and sorry to disagree with just about everyone, but 5-7psi on a daily is perfect if you are willing to throw down an extra $2,000 or so for some light internal work, and doing it "right" the first time vs. slapping a turbo some piping on and calling it a day.

 

[rton20s]

Amen Tony! And thank you for saying that.

It is really funny to see guys come in here who know very little about the 1NZ-FE, or even the xB and shoot it down with only minimal knowledge. Heck, I am a total novice myself when it comes to this sort of thing. But I know you don't count out a car as light as ours just because you can't easily make 200+ hp.

For $2500 you can have enough bolt on power to make these cars respectable and turn more than a few heads. Sure it isn't going to run like a forced induction V8, or a swapped and built or turbo'd civic. But it will be respectable for what it is.

And I have HUGE respect for guys like you, Eloy and a few select others. You are doing what you do for yourselves and the community. You are doing it to truly test the boundaries of or engines (and cars). And what you do for yourselves now might lead to huge benefits for the entire community in the future. And best of all you are not in it to make a quick buck off of the ignorant masses.

I dont think it is mis-information, most of the folks on here dont have the resources to "do it right" and most value their warranty. Im gonna just get an older mustang and build that up.

Why has nobody done a 1ZZ or 2ZZ engine swap? They are on ebay pretty reasonably priced, and it has been done in a echo (which has the same drivetrain as a box) If you want more power and potential, and have the money, wouldn't it make sense to drop in a motor that can take more abuse?

 

[TerribleTed]

Wanna go fast?? Drop a 325 Horsepower 350 CI small block in a Corvair

This car was a bit slow only 0-60 in 4.9 seconds (it had nearly 1000 pounds of extras like, full interior, heavy speaker/sub system, nice heavy quiet box insulating passengers from motor, airconditioning, undercar lighting, etc). I had another one without all the "extras" it went 0-60 in 3.9 seconds. They also handle like go-karts due to near 50/50 weight distirbution. Sorry, they aren't cheap to build, but they arent terribly expensive either. Hmmm Ferrari/viper like performance for under 10G's and some (well maybe alot) of elbow grease.

 

[rton20s]

Honestly? Because for the most part the xB crowd is either the Pep Boys customizers, or cheap bastids. The guys who are willing and able to go buy a brand new car and immediately begin hacking on the engine bay to swap motors are few and far between. Even fewer and farther in the xB community.

And yes, there is a lot of "misinformation" floating around this site and SL. Whether knowingly, or unknowingly spread.

I get what you are saying, but to a degree thats what im talking about. How much abuse do you think our tinny 1nz can take? Do you know, please inform me otherwise im wasting my time and money. Have you personally blown a 1nz, and what was the exact mods you had? Otherwise, you really don't have a place to say such things when you haven't attempted yourself to push our motors. Like i said earlier, you don't need a power house motor to make our cars fast. People are too caught up in numbers vs. reality. I'm not saying you or anyone else falls in that cat., however it appears most here and other forums do. All i can say is, think outside placement and big numbers. Why do you think alot of honda owners are successful with 200-250whp in 90's hatches, coupes, and even sedans with weight reduction. Its not because thats alot of power, its because thats all they need to keep up with the ls1's, 2s, 2jz's, so on so forth.

Ever watch videos of 230-250whp hatches keep up with ferraris, and z8's? Ever watch the videos on youtube of the smart car that can out run the 360's? Theres a reason why cars like ours can keep up with the "big boys".

Why has nobody done a swap? Probably the same reason most don't pour the money into the 1nz. "Pointless"

 

[xjeepguy]

The problem isnt that the motor cant be built right, the problem is that most wont crack into their engine to build it right. They just want to bolt on a turbo and call it a day. The folks who have tried to do what youre doing on stock internals generally blow them up.
