i just bought a 1990 crx si with a b16A3(160hp) block and b18b1/142hp) head dc header aem cam and cam gears i dont know the specs , it has a bigger TB on it i think he said it was from a gsr , short ram air intake , 17 in rims 40 series tires . i was told it had around 180hp and ran low 14's and 13.9 once . well i dont have access to a dyno and the track around here is closed now for the wiinter . ive been reading through multiple forums and cant find anyone with the same setup or whattimes they run with it i just want to know if these numbers are possible with the setup it seems quick just not sure about that quick thanks for your help .

 

b16 block with an ls head..?. .
B16 block is torqueless and the ls head cant flow that much air..
And aem doenst make cams,,They make cam gears but not cams..
I honestly dont see that motor set-up running 13's..I think you were lyed to..
And are you sure its a b16 block with an ls head.?? And not the other way around

I think you were lied to. Why would someone put a b18 a/b head on a b16? Check the block code. Hopefully you have it mixed up. If you have a b16 head and a b18 block then i believe what the guy told you.

 

i was just thinking.... what would happen if a person bought a b16 and b18. normally you would use the b18 bottom with b16 head. but when you do this, left over you would have a b16 bottom and b18 head....what do you do with this? sell it to some sucker
just a thought :shruggs:

 

It's like a reverse LS-VTEC. My friends and I thought of that... and what a terrible motor it would be. I think you have it mixed up, pop the hood and see.

 

im positive about the block and head its not vtec , i couldnt belive it either after reading about swaps he told me he auto x and used that block bc that complete engine has 160 hp and used that head to try to raise the torque bc that complete moter has 127 tq doesnt really make sense to me just learning about honda's and he didnt want a vtec for auto x and the brand for the cam is probably my mistake . could you guys give me an estimate about the numbers , and as far and changing the engine setup would i get better 1/4 mile performance with getting a b16a3 head or a b18b1 block i would like to use some of the parts i already have thanks

 

but i will check in the morning just to gurentee it , oh and i did a search for casting numbers location in this forum couldnt find anything caan u tell me where to look thanks

lol

 

I hope you got it mixed up.

 

backwards ls vtecs have been done. why not, b16 bottoms and ls heads are both kinda worthless. might as well make it run.

Look on the block near the tranny..There will be an engine code there..
No one can guess the hp numbers..

A b16 head would require adding 4 wires for vtec..and getting a vtec controller or vtec ecu..And you would have to get the right obd head ..What obd do you have anyway?? Seems like you wouldnt know anyway

A b18 shortblock would require takin the motor out of the car which is more work ..
But it's up to you..
and as far as 1/4 mile times..no one can tell ...to many variables..

You should have did research before you bought the car..

 

OBD 0 ( ok hopefully u guys read back this far i went past my posts for the day but i checked the numbers on the block and its not what he told be kinda glad about that after the neg. things said about what i thought the setup was its a b18a1 block can someone tell me how or where to find the casting numbers on the head can i find them without removing it thanks . way things are goin probably a b18a1 but i would like to know for sure and me and the guy i bought the car from gonna have a little talk thanks

What?? I always thought LS heads don't match up with dohc vtec blocks? Cause of the extra oil passages or something. Any info?

But oil passages can be relocated

 

How expensive would that be? The cylinder head is aluminum correct? Wouldn't that cost some money to get the oil passages filled? I don't know what I am talking about maybe I'm way off.

 

so he did a LS/VTEc swap himself, and stuffed you with the leftover parts....


Sounds like a nice way to scam somebody out of some cash.

I don't think that will give you much information on a ls head on a vtec block. It's not quite as popular...

This will be the next hot fad! The Reverse LS-VTEC!

 

Has anybody ever done this successfully ls head on a vtec block? curious as to if it would work.

 

If he told you a GSR throttle body is larger he is also lieing there.

same principle, though

 

well the CR would go from 9.2 to 9.73900669945766:1, so it is a little higher, but still there is no cam adjustment. Would you use the redline from the b16 or the b18? Could the b18 head handle 8000?

 

sounds like you got got....but you may possibly be starting the next new trend with the reverse ls-vtec

 

We need to see a dyno on this... I wonder what the torque would be like? sounds like it could be a cheap motor for blowing up with FI.

lol, did someone say homemadeturbo?

I guess all you have to do is block the oil drain galley and the oil supply for vtec in the block, just a little plugging and jb weld... Wouldn't you basically wind up with a really expensive ZC that sucked a little less and needed a gang of other **** to swap in?
