im getting a free a6 motor with thrown rod. i currently have a 90 civic 4dr with a d15b2. im planning on using a a6 head(b2 head basically), si tranny, y8 intake manifold and a PG7 ecu. what else can i use for my d15 to get more power? any help appreciated

p.s i dont except many replies because most people on this site are d-series haters.

 

Maybe throw in some (i forget the numbers) first gen integra pistons? There good for a nice bump in compression, look around, I don't think you have to change anything to get them to fit.

BTW I love d-series.

 

They are d16a1 pistons. With a thrown rod, I would look into the head first to see if anything was damaged. Better be safe than sorry.

 

i already have a a6 head, and tranny. im just using this one spare parts :D

 

Replace the rods and bearings. Replace rings and whatnot since the block will already need to be apart. PM7 or P26[Integra I believe?] pistons have the same bore, but will bring the CR up. Since its a SOHC head, go get a good cam and have a local shop port and polish it up. Get a valvejob, I believe you can use the D16Z6 head gasket, its a single layer metal hg so it will also raise the CR. Baffle the oil pan, replace the oil and water pump. Use the D16Y8 manifold http://www.geocities.com/joeyp....html . Go to http://www.maxbore.com do some work on your throttle body. And a decent header, I recommend the Megan Racing Ebay header, here's my review/write-up on it https://honda-tech.com/zerothread?id=1257061 . With all that and an Si or Zc trans and you would have 1 fun little daily driver. - Darrell

 

IM A B & D SERIES LOVER....
upgrade your cams for your b2 and also I/H/E

 

definately i/h/e. i might decide to go junkyard turbo though.
