this is really interesting. thanks for the help. so there is no numbers after the engine codes.

[Pballer2005]

yeah that's what it said, but it also said that wasn't entirely accurate.

 

" look for a knock sensor, low-rise maifold, and 2 layer head gasket (I guess they said you can count the layers on a corner). "

correct, no numbers

[97blackonblackcivic.]

correct, no numbers

 

 

isnt there a b20b and its usdm??? it has no number.

the engine im trying to get is a b20b and the guy claims its jdm

[airjordan223]

theres a B20Z which was in the USDM CR-V. the B20B is mad jdm yo

[Pballer2005]

from that article it looks like the only way to really tell is to take the engine appart and look at the codes on the pistons. but other than that i would just go with what you know so far

Does it f*cking matter if it's JDM or not?

 

It's not like you're gonna' gain that much more out of the deal.

please if u dont wanna help me stay out of here.

i need the good piston, and the good block. im planning to change the head for a vtec head.

Even more of a reason to ask whether or not it matters if it's JDM.

 

If all you're going to do is scrap peices of it then what does it matter?

 

Save yourself the money and go with what's cheapest as far as the motor goes if you're intending on doing a build.

some times cheap stuff endup costing more man. not my style.

Orrrr sometimes overpaying for a "JDM" motor only to find it's USDM or has little or no difference at all to the USDM counterpart is a waste but..

 

Ohhhhhh well.

[airjordan223]

isnt the wiring different for the JDM motor?

[97blackonblackcivic.]

i dont know. thanks everyone that helped me. i guess ill keep looking for the right answear.

[airjordan223]

this is from a convo i had with a guy who did a JDM gsr swap and i asked him what he had to do in order for it to work

 

not really any differences other than the harness is opposite... so use your harness from your d15 and get the harness from hasport ----> http://hasport.com/catalog/product_info.php?products_id=100 this will give you your knock sensor wiring as well as vtec selenoid wiring, one other one too but i forget what it is, some sensor on the intake manifold, but this makes the wiring simple, just wire up your old harness on the gsr engine.

i did my friends b20 swap for him and the wireing is different in that the plug connectors for the ecu is different thats about it and some of the wires will be kinda short depending what car your butting it in to and what ecu ur using (ie.obd1 or 2 )

How much are you paying and what all comes with it? If you don't mind me asking...
