ok i have heard and used the d-series calculator but i search and search and cant find anybody useing this combination anywhere.

does anybody know of anybody that has used d16a1 pistons with y8 head, and any sort of d16 block?????? everything else basically stock on the motor(maybe some bolt ons).

it is suppose to yield a very high comp rate. but i havent found any one who has done it yet.

 

D16 block/Y8 head/P29 pistons (d16a1) = 12.6.1 est. compression.

Many people have used that piston/head combo with sucess, but you need to tune,tune,tune and tune some more make them work right (91 octane or more). If you want to lower the compression to say at least 11.5.1, you can use a COMETIC or APEXI .060 or .065 thickness head gasket.

and have fun doing it !

 

I've PM7 pistons in my D16Z6. Works ok, CR is 12:1. Because of lack of squish, it needs 35 degrees of advance at WOT. I run 98RON (~93...94 [R+M]/2).

 

Ive been running this setup for 4 or 5 years. Its decent, run the highest octain you can. By build info is in my sig.

tips=
use acl race bearings
use arp rod bolts
if you can have your block bored .5mm over and ger .5 over a1's
the added compression wont help unless your head can flow cfm's you will need a camwith decent lift and portwork to take advantage of it.

 

i just want to find some all motor d-series vids. i have just gone turbo and finally got it all in(im 17, been saveing since i was 15). but i liked n/a because when you get on it....its already there and there is no waiting.

dont get me wrong turbo is awesome/fun, just when i get older and a real job i think i want to have a all motor d-series and work some b-series with it. it seems like it wouldnt be that hard(by hard i mean money wise) to make a 150whp d-series if you just know what you are doing or how to boost the comperssion up.

say you did just throw pistons in(the setup i am talking about above). with maybe a cam(59300) do you think you could make 150whp?

 

i don't think so..i mean 150...i say do what you are doing get the cam get some good header that'll put 10-15 hp...bisimoto, smsp should have it..and TUNE IT!!..i have a zc with y8 head and compression it high...but i am build a a6 block with arias piston that will put down a 10.5 compression and add the y8 head...someone please do that math..10.5 comp in a a6 plus the y8 head...someone get me the answer..but yea i have crower stage 3 but i don't want it to be too aggressive...and believe me you'll love the sweet sound of high compression..

 

so what kind of #'s do you think i would yield with 59300 cam and a1 pistons with y8 head in any block. and if i left everything else stock(basically y8 everything and the above added) how much powa do you guys estimate tuned on crome?would i need bigger injectors?

130-160 whp depending on the tuning

 

would i want eagle rods for any reason? or would that be if i wanted to run nitrous or not?

 

How many rpms are you going to spin? I have the high compression setup in my y8, i just put on some do it yourself ITB's. It's a lot of fun, but i just use it for a track car. I also run 110 octane. Now, i built this setup for very cheap, and there are a lot of ways that you can go about building your motor. You really need to decide what your going to use the car for, and how much your willing to spend. Once you step into rods, you might as well get cams and all that too, so you can spin some good rpm's. Just my 2 cents

 

i'm switching over to turbo..and definitely i'm going to build my block over my head..why?..rods are the first thing that im going to get because d16 rods are so fragile they'll break on you if you are doing to much with a lot of power

Thats pretty vague. All motor setups don't really need to worry about too much power for the D-series rods. More of an rpm issue. I understand what your saying, but that's like saying you can't boost 15 psi on a stock block. Make sure your swapping your pistons too, when you do the rods.
