the 1zz when trd supercharged has the same power but much more torque and no worries about bending valves.....
the trd kit is 1920.00 when you know how and where to look.

problem is the majority of simple stuff do not have carb certs......

and i dunno what state has a 100 foot 30db law but it sure isnt california.

 

Okay, so the 1zz and 2zz blocks are pretty much the same length (even though different materials) but the overall length with head/accessories seems somewhat different. Anyone with any length specs at all? Thanks.

 

in the new scion books at the dealerships their is a xb that has 400hp that did an engien swap they put a toyota 22 rt motor in it

Much more than an engine swap. It has been discussed in the forums several times. That xB was actually mounted on an older Toyota pickup frame allowing the owner to very easily run the 22rt.

 

my sister has a 2005 corolla so i can check the 1zz length.if i remember correctly from a few months ago when i measured a matyrix the 1zz is about 1 inch longer.

 

That would be great info to confirm. Thanks, HotBox!

 

From sikbrik-

"How much of an overbore, and how much power do you really think that would give you? You'd need a 3mm overbore to get you to a 1.6 liter. That's huge in the engine world. Are the bore centers even spaced far enough apart to sleeve with a 78mm bore?"

As you say, it really depends on the bore center dimension, and I don't know what's there. If the motor could be punched out w/ sleeving to get 1800-1900 cc's, it'd probably be worth the trouble. Only an engine shop that specializes in that kind of work would have the answers...

I've seen a variety of engine swaps turn into complete clusterflucks over the years- even ones that appeared easy often have undesirable side effects. Swapping out aluminum block motors for cast iron can badly compromise handling, for example, even if it's a relatively straightforward bolt-in operation...

So, be careful what you wish for- you just might get it, and it probably won't be what you thought it would be...

 

the 1zz is also an alloy block but all signs point to it being too long to fit without cutting the chassis. Not my cup of tea.

 

I remember an issue from Import Tuner early last year that featured an XA that was boosted and stroked to 1.7 liters putting down 217 HP. So that does prove stroking the engine is the best option.

 

that article was a lie and that is the now 4efte motorswapped car.

 

Aside from that, it doesn't really prove anything until you also prove that someone can't make 217hp on an unstroked, or even destroked, 1nz.

 

1nz is not a stong building powerplant.

 

I tend to agree with hotbox, so that would also apply to any 1.7 liter "stroker" 1nz as well. Not worth the time/effort/expense unless you've got connections to a machine shop or too much money/curiosity to keep you grounded.

Overall, it seems that the best you can do with these cars (reliably) is some mild forced induction and maybe a few little efficiency tricks here and there and hope for 160-180hp max.

...is anyone even considering a 1zz? I've been comparing pics I find online but don't have access to a 1zz block to take measurements. Mounting looks nearly identical , although I'm sure the front mount is offset somewhat differently. Overall length would still be my biggest (and really my only) concern. Overall width doesn't appear to be that much different, especially on the newer engines with the similar composite intake, etc.

With a slightly modified NA 1zz, you'd be looking at that same 160-180hp you would have got from the boosted 1nz. Maybe more money, maybe the same, maybe less. It opens up the door for bigger and better things, though.

Did I read somewhere that the 2zz fit that car (you know, the echo hatch or whatever it was...) lengthwise but the overall width was the problem? Or did they have to channel the 'frame' somewhat to accomodate the length?

 

2zz and 1zz are the same size so it should fit the same. and i believe on the vitz that has the 2zz they modified the firewall and notched part of the subframe.

 

cool
