Default D15b7 internals

For the d15b7 are there any forged/aftermarket rod and piston options available? And if not would any other ones work like rod and pistons for a d16? I've searched and every thread says that "(insert name here) sold them but there discontinued now)

Custom for aftermarket. Another words, no but you can have them made as most rod companies have the ability to make custom rods.

You will likely spend more on rods and pistons than you will on a used B18C JDM type R motor.

The other option is custom pistons on D16Z6 (137mm) rods. The B7 rods are 134mm.

In all honesty, the cost involved is not worth the end result.

I'm looking to play a little that way and well, I'm just being dumb and dumping 1500 into a b7 minime setup for the learning experience. That 1500 is better spent on saving another 1500 and then doing a 3000 B series job of some sort. Foget about the B16 head though, that typically is 3000 alone as everyone wants one for the LS-vtec or whatever it is.

Yea I'm starting to see that but I'm trying to find out now if there's a "franken" rotatating assembly. Looking like a jdm d15b crank with ls rods and viatra pistons would work. ATM I'm trying to double check all options

I think you made a typo, as the B16 head is definitely not $3000, did you mean to say $300? That is about the going price for a stock one in my area.

Literally anything would be a better investment than putting forged internals into a D15. Literally. Anything.

The z6 is my preferred option not sure why but I have a love for them. Wanted to see if I could do something with the d15 since this is a flip/project car but oh well. Looks like turbo z6 is the way I'm goin

Yeah, even though can't seem to find a b16 head in my area right now. Seems they are a hot commodity here in BC for the LSvtecs or the b20 block/b16 head hybrid.

Also I've been corrected, there is some decent forged internals on ebay, just have to replace all the studs with arps. You look for D15B2 internals and you can find forged 134.5mm rods.
