picked up a "jdm" 97 spec itr motor and transmission for $500. I will be using the head on my b20 vtec how can i tell if the head is legit? has no green mark on back of dizzy head stamped pr3-2 and p73 00 pistons.

 

Sounds stolen and you sound shady for buying it - good job!

 

was it blown up? unless the block is shot that's either an idiot selling it or it's seriously stolen and now you have the hot motor. i'm guessing the block is bad since you're using a b20 rather than the vastly superior b18c? either that or the b20 is sleeved. pr3 anything is a b16 or itr head, which really doesn't matter if you're doing any port work. some of the early jdm itr heads had no port finishing but all after late 96 had a hand blending that became cnc in 98

how to tell a itr head



Now why was this so cheap?

 

lol

 

i just got seriously lucky the guy i bought it from is a friend of mine and was keeping his honda parts at his moms house after he moved out. The rents ended up giving away his crx full of parts cause they were tierd of seeing it sit and his motor was next to go so he sold it to me before they scrapped it.


I pulled the head ports do not look polished or ported . Im thinking i have the early model itr?is it just a b16 head filled with itr valvetrain? Do these things suck compared to the 96+spec? Pistons are stamped p73 00.

 

Look at the other thread and then at the pictures is my old FS thread. They show the stock porting.

 

Graciiiiiii im going to garage to check right nowwwww

 

take pics and post them

 

Green paint on the head behind the distributor.

 

We have a winner!!! Paint was pretty much no existant. Thanks guys
Motor is a 97 spec

 

you got one hell of a deal. major props !

keep the entire engine, don't waste your time building a time bomb unless you spend the money to keep that b20 alive with real sleeves.

 

the green paint its really rare, not all head have it

 

it's usually just worn off

 

you can bbbbaaaarrreeellllyyyyy see it on mine.....


but its there!!

 

waattt, im pretty sure theres a big thread in the all motor section with people running some pretty big setups on stock sleeves. Done right stock sleeves on a b20 are fine

 

starting a new thread still need yall guys help with this!!!!

 

*pulls out spoon*

 

yep, they run. if an engine only needs to run for a few races or a short period of time. all stock b20 bottom ends i have seen that spin over 8,000 fly apart fast if you try road racing and might, might make it a year of drag racing if you go a couple times a month. if you gram balanced one and upgraded the rods it would be a considerable improvement but the sleeve walk still is going to cause issues in extended high rpm use. the b18c isn't perfect but it is stronger than a b20

 

Look at my other thread titled ITR motor worked for two days then shut off

 

found the green mark yesterday got my answer this thread is ooovvver check out my other thread
