Right now I have a D16z6 out of the car in unknown condition. in the car I have a D15b2. I was wondering what would make more HP/tq. Should I swap in the whole z6 motor, or should I just put the Z6 head on the block thats in the car. It will be an NA build as I have no desire to fool with turbo's. Either way the head will be sent to the machine shop for refurbishing.

I am thinking that the head swap will be the easier/cheaper route but I think the Z6 will give me a little bit more tq and will be more reliable because i'll probably rebuild it.

If I am missing any info just let me know and I will fill in the blanks if I can.

 

How much $$$$ you got or do you have $

 

hehe so mean... but an important question to ask!

i've been wondering this myself, which motor swap would be best. i think a jdm zc motor swap is the easiest and cheapest based on $/hp terms. look into it and it requires no fabrication! direct bolt on.

 

Yea the whole swap would be better, but it might be easier to do a head swap but it won't have a good of bottom end (tranny,less hp/tq).

 

I already have the Z6. whole motor. Dizzy, intake manifold, block, head.

I guess what would It cost to rebuild the Z6 and how much power would it make vs. the price/power of the head swap.

 

just slap a b16a in it and your good to go

 

google it no more stupid questiong

 

how much do you want to make?

 

If I could make 135whp that would be outstanding.

 

^lol get a d16y8 with exhaust youll be close to it

 

Why would i do that when I already have a D16Z6 for free? If you cant help me with an answer to my question please dont post.

 

135 hp? And your asking for help with an attitude?

135 hp..... Bolt it your D16z6, cams, header, mild port, push off cliff. Done.

 

jb weld two d15b2 motors together with a custom made timing belt and you can have 184hp...!!!

 

why dont you do some research instead of asking stupid questions if you dont like what people have to say then dont start threads which are still not gonna have an answer that YOU want to hear!

 

I have done research. I have googled it. the only thing I have found is one video on youtube with d15/z6 mini me. I havnt found anything on the cost of rebuilding a motor vs the power.

When the only options are "mini me" and "D16" why would anyone say "b18" or "y8". I dont have the money for either. If I did, I wouldnt be to worried about the cost to rebuild the z6.

 

soo much bashing for no reason. anyways i got some experience in your department so im going to help you out.

I had a eg ex coupe with a z6 head on a stock d15b2 and typical bolt ons and it made decent power. I raced my buddy in his 94 Si hatch with stock z6 and typical bolt ons and i pulled on him. Same transmissions and his car was lighter. So with some mild head work im sure youll be happy with the result. I think just swapping the head would be just as difficult as swapping the whole motor since youll have to do the same wiring in order for it to work correctly.

 

DD the b2 while you rebuild the z6. My $0.02 Especially if you dont know what condition the z6 is in right now. Any clues about its mileage? Was it running when it came out of its previous engine bay?

 

The guy I bought the car from gave me the Z6. he said he was cleaning out one of his buddies rental homes and found the motor. so I have no knowledge of the Z6 at all.

Thanks for the help guys.

 

Do some searching. This isn't hard man, if you can't figure out how to search for the answers you need, you shouldn't be putting hands on your car.

 

When i was looking at rebuilding a d16a6, I called around to machine shops to see what it would cost to have the block and head all aligned and honed. then i priced out gaskets, seals, rings etc. took me a while to figure everything out, but honestly it gave me a better idea of what I needed to do/ buy than opening a thread would.

 

If you can do the work yourself why not try installing the Z6 and find out how it runs in the first place if at all,it will only take some time and possibly an obd0 to obd1 converter harness(if you have the ECU).
Every thing you do will need to be done to run either the engine or the head swap anyway and at least you will know how the engine is and what you need to do to it.

 

Thats not a bad idea. I'll do that.

 

the people suggesting b series arent that out of line... if you use the money youd save from building the d16 and the money you could get from selling the complete d16, maybe even the d15 too, youd have plenty for a nice ls or maybe even a b16. just something to take into consideration.

 

I didnt think of it that way. What is a ballpark price on what I could sell the D motors for?

 

well, im not totally sure, dont see them for sale often, but id say probably 300-400 for the d16, maybe a hundred or two for the d15, another hundred at least for the tranny if its manual (i could be off a bit but thats probably about right). so right there youre sittin on 600, plus you must have another few hundred if you were planning a rebuild... i see ls's go for 400-500 all the time.
