haha i tink its kinda funny that everyone talks about swaps all the time and its all over the forum. no offense to anyone but, 3sgte?! does that even fit in scions?! if so i wanna see some proof. i can understand the ZZ fittin in scions. both fairly new cars.

and has anyone actually swapped a different engine into any scion yet?!

again, no offense to anyone. i want to swap engines myself but as many have stated before, swaps arent good if there is no money!

i think the zz setup would be the best. And why do a swap? Just get the little 1nz-fe engine built with high performance internals and a huge turbo. That's what im planning to do.

hmmm interansl = increasin compression

high compression + turbo = VERY VERY BAD

well thats just my thoughts, please correct me if im wrong but i dunt tink thats a good idea. unless your talkin bout sumting different.

i dunt tink there are aftermarket cams for any new toyota. 1nz = 8.1 compression, very very low but puttin a big turbo to increase compression wunt do much either because of its small block.

hmmm so many possibilties. please tell me your exact plans. lil curious tats all

hmmm interansl = increasin compression

not necessarily its your choice to go with high or low compression pistons

hmmmm. how would you mod internals without increasin compression?!

all i can tink off is cams but i dunt tink there are any aftermarket cams avalible for new toyota engines.

pistons, storker, bore? increase compression doesnt it?!

port polish migh be a good idea but is it worth it?!

just get lower compression pistons. stroking and boring doesnt increase compression (i could be wrong) but to my knowledge those to things increase the displacement thus letting the engine take in more oxygen into the cylinders. adding a cam will not increase the compression it will just give it more lift and duration (depending on the cam profile) which will also let more fuel and oxygen into the cylinder chambers. if you go with a thicker head gasket you can lower the compresion without any internal changes. but if you want to lower the compression just get lower compression pistons. im not sure if theyre any out for our engines but aftermarket pistons have different specs to them to suit your needs

there are 2 ways to do internals, what you are thinking of, in terms of increasing compression, is for a naturally aspirated car, where you want the higher compresion for more horsepower. for turbo cars, there is internal work that needs to be done such as sleeving the cylinders and using lower compresion pistons so that when you boost you wont crack a cylinder wall. all cars running a high level of boost should be built. and btw, yes, a 3sgte can be swapped into a scion. it will need different motor mounts and custom axles, but it can be done. results of this swap will be posted as soon as its done, look for it in the fall show curcuits

I was thinking, maybe a very mild cam, there are so many names for these but i call them piston rods, and pistons designed for turbo use, and a turbo. So that way i could get the stafford fabs turbo kit and go all the way to 18psi, with the thought my engine can hold this a lot better.

higher CR and lower boost turbo = very nice. A lot of race cars use higher compression and lower boost. Final CR is what really matters anyway.

Reminds me of Mad Max:

Speed is just a question of Money. How FAST do you want to go!!!

Why go with a mild cam? If you're gonna do a cam, put something aggressive in there. If you put a mild cam in, you are spending money on a mod that won't do much. If you are going to go N/A you need to up your compression, port and polish your intake, and go with aggressive cams. And remember, you need some backpressure in your exhaust or you'll have no torque, so use a muffler, just get a high flow one. :D

back on topic.... is there a motor swap proven to work on the market?

Well the place to start on finding a motor that will swap in is doing research on what drivetrain parts Toyota's share with our Scions. Find Toy's that use the same transmission, or at least the same bolt pattern on the bellhousing. For example, I hear somewhere that the newer Celica's transmission shares a case with the ones used in the Scion..... I could be wrong. But if they are similar, you could mount up that transmission....... then with some mods to motor mounts, whats to stop you from mounting up the Celica motor.

To sum things up....... do your research as to parts numbers used in our cars and Toyota's.

this is thread is exactly what i have been thinking about, but never posted. too many people post about doing this swap or doing that swap, but no one steps up and does it. i am tired of all the posts about asking what engines to swap will work. :roll:

Porting and polishing the intake? What kind of plastic polish would one use? Sounds like some of you have read one too many issues of Hot Rod magazine. These are MODERN engines and the designers would not give up any easy or low cost efficiency (IE Horsepower) when the engine was designed. If you could come up with a practical engine swap I would be truly impressed. Scions were not designed to be drag raced. If you want to be a racer you bought the wrong car. A fox-bodied Mustang or later model Z-28 would be a much more pleasant starting point. Motorcycles can fill your need for speed rather cheaply also. But a Scion is not a race car- never will be. However fast you can possibly get a Scion to go, someone with half the investment will give you a bare-assed spanking at the drag strip. Food for thought........

yo man, you can pull plenty of power out of a good port and polish, it's not that the engineers want to give up the efficiency, or power, it's that the precision necessary to do so is not available for a mass production assembly line, i bet you could squeeze 3-4 horses easy, and most people are capable of doing it themselves, i'm 15 and i started out by p/p-ing my lawnmower engine, and now i've done nearly every one of my friends cars, and taught them how to do it too, it's simple, it's easy, and it works, a dremel tool and a steady hand can pull power outa nearly any engine. PS, my lawnmower runs an 1134 in the 1/8th mile at 55MPH on a 15 shot of nitrous, that's better than most of our scions...though I will admit that's sad, when i pay off my xB i'll send you my timeslips before and after i port

If you have a nitrous powered lawnmower....than you might be a redneck! :lol:

People can talk all they want on the forum and do another

Truth is, people are paying payments for their scions and it is “Idealistic V.S. Reality”

How many people can afford a Scion that is about 16K, and highly modified for maybe another 16K? On a brand new scion

And if I have that kind of money…
I would rather get an EvoVIII or STi and out perform Scions left and right…

Hey im 15 too!!! and yea P/P will pull some more Hp outta any engine... Ive seen a Cvic si hatch(5th gen) pull on a (6th gen)Si The hatch had some Porting and polishing a Header an exhaust and a intake and intake mani. The si had Intake and exhaust...

Yes they were both full out racing it was at the track it suprised me that the Hatch took him of the line and they were neck and neck until about an 1/8 of mile....

The hatch ran a 15.8 and the Si ran a 15.2

What dumb A** would f*** up a perfectly good brand new car by swaping motors? Motor Swaps are for when you wear the 1st one out. I've upgraded some old chevy 4 banger vegas and s10's to small black chevys but they were all OLD. I've swapped out an I6 in a full size truck for a bigblock but it was 15 years old also. I can see adding some new pipes to a new car and an intake. Hell MAYBE a turbo but a motor swap? Those things aren't cheap and I wouldn't sink that $$$ in a new car that runs fine. If you wanted a faster machine for little green get a bike.

Do you really have to worry about tossing out the stock 1.5 and 'ruining' an xB?

Yes, I think it's silly and wasteful to buy an M3 only to pull the motor to swap it, but the xB is priced so that the new car and the motor of your choice could be a reality for less than $20k. And nobody's really going to cry over the stock 1.5 going to 'waste'.

The only hesitation I have about buying an xB is the weak motor. Trying to turbocharge an FE Toyota motor is not the most reliable idea out there. Swapping in a slightly larger n/a 4 banger (2.2 - 2.5 liters) would be a great, realiable way to make this car acceptable transportation for a lot of people.

why does everyone always make these forums into something that they are not. who cares if you don't think the box is a racecar. who cares if you don't think an engine swap is useful on a new car, etc etc (sorry i singled those out, just the last ones i read). there was a question that started this topic, and people wanted an answer, not to hear you saying that its not right. they want a bigger engine cause they feel that their xB/xA is to slow. they didnt say that they want to go drag race a supra or a viper. its the whole reason why cars are so popular, and why we love them so much. upgrading whatever we have. consider that maybe people just like the way the box looks, but not the way it drives. individuality. that's what scion is all about. oh, and btw, the only engine that will maybe fit (although you would need custom motor mounts at least, probably more) is the corolla engine (mr2, matrix, and celica). sorry i forget the code for it.

The problem here is that some posters have no clue what they are talking about. Porting and polishing an intake? The intake is plastic and the interior is the ideal finish to start with, the ports are perfectly matched as is the gasket. These motors do not compare withyour lawnmower, Uncle Bubbas' 55 Chevy, or your buddies 10 year old Honda. I have a little experience with Toyotas and would be damned impressed to see any pictures you care to post of your successful motor swap. Until then , sweet dreams...........

I hate to dredge up an old post but I have been doing the research like you are talking about. I have been thinking about swapping in a Celica GT-s motor for a while and here's what I have come up with.
Engine: You would need a donor motor. The cheapest that I have found the motor online was 1200 dollars. Thats without an ECU to control it and the VVTL-I and without accesories i.e., power steering and a/c. Also, I'm still digging on this but do the ECU's in these cars tie into the whole car. Things like ABS, VSC, TracControl. Are these all subsystems that have anything to do with the engine's ECU. If they do then using a Celica ECU and engine is out of the question. This motor pumps out 180hp before being modded. In comparison to the 108hp the Scion motor puts out, or even what the Blitz S/C or any turbo on the Scion motor has yet to put out. Nitrous guys we know what you have so hold on a sec.
Transmission: The stock Scion transmission part number does not cross with any Celica transmission part number. I'm still researching this. I thought about your idea of using the Scion gearbox, and seeing if the bellhousing from a different transmission would bolt to it AND the motor. But I need access to the parts to see this and I'm still working on that.

I'm really thinking about this. Why would I want to destroy the stock wiring harness and everything. It's still under warranty. If I pop the motor with a turbo or S/C I'm screwed too. Like I said, it's in the air and probably won't happen but it's an idea.

i can count the IQ of this thread on one hand..

specially the "the 3SGTE engine is too old, it wouldn't fit" comment..

cuz aparently as the engine gets older, it grows right?

LMFAO at this useless thread.

Someone tried fitting a 3sgte in his xB and the AC and power steering wouldn't fit...so he took it out. I think it got too old. :lol:
