Anyone tell me difference between the 2 besides HP difference.

Thanks,

doesn't everything just bolt up from the USDM to the JDM?

 

[elim70]

what I guess I'm trying to say is

1. is it just a direct swap?
2. is it cheaper to rebuild a us to jdm specs, or just swap
3. If I go the build route, what parts are different?


thanks

Whats the point of going JDM only to use USDM ?

 

[MRtuned]

good point. it wouldn't really make sense, lol.

maybe I'm not phrasing right. I want to make some small upgrades. I will rebuild the motor sometime in the near future. My son has a probe gt. He wants to put in a klze j-spec engine. the only difference between the two is ecm, intake manifold, camshaft specs, and .5 points in cr, block is the same. Now a klze can be had for about $1000, but to do a rebuild using the klze parts would be considerably more than just buying a replacement and dropping it in. I want to know if the same holds true for this engine. I dont plan on going crazy, just want a mild HP increase and a newer motor.

thanks

there are more distinct differences but it depends on the generation.

gen 2 jdm has a different ecu, no egr, ceramic turbo (very small upgrades)

gen 3 has much better turbo, 540cc inj, better fuel rail, different intake manifold (huge upgrades)

i own a jdm gen 2 and have used usdm parts pretty routinely. can order anything at local toyota dealership. main difference i have seen so far is the 93 jdm uses the 9 bolt exhaust manifold that wasnt used here until 94 (iirc?).

gen 3 is more of a hassle but there are a number of dealerships that stock parts. try jay marks toyota in texas.

jdm are way cheaper to do a swap atleast when i looked. i foudn a good condition usdm motor for 4k and a jdm for 2.3k hmmm i wonder what i will use.

2nd gen -> 2nd gen... The power difference is due to a different turbo, emissions equipment and fuel maps. If your state has strict smog laws you will not be able to get away with running a JDM engine. The power difference is trivial if you plan on modifying your car. Although the JDM CT26 is much nicer to cruise around with IMO.

 

[MRtuned]

it has a ceramic wheel, right? whereas the usdm one doesn't?

Correct.

 

[elim70]

ishcoleobo, that was kinda the answer I was looking for. I live in NY. Emissions tests at present are on 1994 an newer vehicle so that really isnt an issue. I guess I will rebuild my usdm.

thanks

I love my JDM 3SGTE. good gas mileage too.

 

[MRtuned]

not when you're boosting

 

[nepopolus]

lol...ya i can watch my gas go down if i drive it hard but while in vaccum....it never moves...kinda freaky i keep thinking my gas gauge broke.
