recommended pistons to pair with Carrillo rods - s52

[skuurt skuurt]

As I dig deeper into my e30 project, I'm already planning on the second motor setup. It's currently getting an m52 thrown in there and I will be leaving it stock other than hg, arp hardware and cams. The turbo I'll be running is a gtx35r. This setup is for just dialing in the car entirely as I bought it stock and am turning it into my track car/event car.

Through my friends shop, I can get carrillo rods for iirc $1,170. I can get deals on Wiseco pistons. Not sure of their offerings for the s52 platform. I'm sure they will handle decent power. I don't have a power goal in mind. Basically the highest I can put out reliably (15-20k mi on the setup would be grand).

The shop that's helping me with the motor swap recommended I run e85 with the high compression on the m52. With building the s52, I can go to different compressions. I will mainly be running e85 or race fuel. I will have maybe a map for 92 octane in case I get stuck without fuel options on the way to an event/show.

I'm also considering the Vac motorsports head for the motor as well.

On a side note, I'm looking at running a "The Driveshaft Shop" driveshaft. With the zf transmission am I able to run the 1 piece e36 carbon fiber driveshaft on my e30?

I would run 9.0-9.5:1 with e85, 8.5:1 for pump+meth. CP's, Wiseco's, Je, they're all proven. Id go with an oringed block or a cutting headgasket, ARP head/rod/main studs, and to really take advantage of what a forged s52 will do, a 3.5inch exhaust, twin walbro 485's and a -10an fuel feed line, -8an return, 1000-1600cc injectors for e85. Also a big clutch. I'm not sure about the driveshaft, I think there was a thread about it recently on bfc.

Making it last will come down to having a good tune and not pushing any one part of the setup, like not pushing a small fuel pump, some 80 lb injectors to 95% duty cycle, or running stock fuel lines
