Hey guys my names Tony I represented Randys ring and pinion/ Yukon gear at this last years dyno and burnout day out at Hoss's place. But anyway im building a 4bt and im wanting to put together a set of compounds for it. Nothing big, im keeping the ve pump. I know plenty of you have knowledge on compounding so im hoping I can get taught something here. And yes a single turbo would suit my needs but I like the fun of a challenge. I've been on 4bt swaps website as well. So on to my question. I've been reading that a 12cm housing works well for the small turbo in a 5.9 setup. So would you think the 9cm hy35 would be good with the 3.9? Or maybe an hx30/hx40 combo? Im on a budget and im just wanting some street compounds that will help clear up ddp stage 3's.

 

what about that 9cm hy35 over a S366/74/1.10T4? i've never done compounds on a 4BT but it seems to me like that might work or there is a S256/62/.55T3 turbo that would possibly be a better choice then the hy35 seems like that would stand a higher pressure ratio then the hy would and with the 366 on bottom thats enough air to support +500hp
