Banks Sidewinder vs GM 6.5 turbo setup

[mattthebrat]

Just sold a banks kit on Flea bay for $800 complete.

I prefer the Banks kit for the 6.2. They flowed real good and made more power than the GM stuff did.

MGW, do you have any numbers on efficiency or HP differences between the banks and Gm setups?

Kenny you talk to Dennis about an ATT for that rig? Last time I hooked up with him he was thinking of trying it on some alternative uses beyond the 6.5

I actually did TD but my problem now is from what I have gathered is my 6.2 has the heads where the injectors point away from the valve covers and the 6.5 Manifold itself will hit the injectors. I looked at my 94 and the heads are definitely different and I really can't see the sense in swapping heads on a motor with 58k. Seems the Banks is the way to go although I was curious if the ATT bolts to the Banks manifold. I was considering calling Banks and seeing it I could buy the manifold alone. I could have the pipes fabbed and to be honest I know they work fine, but I don't love the way the turbo connects to the 6.2 manifold. I was thinking about using a Banks with an F intake of a 6.5. I saw a guy who had a 1/4 inch spacer laser cut for the manifold to clear the injectors but he had the 6.2 in a Landcruncher. In the CUCV the manifold barley clears the frame now. I don't think a 1/4 inch is feasible. The ATT would be a good choice with the Banks though if it would work cause I could have Dennis make me a straight pipe off it instead of the 90.

NO good. Those use the 6.5 Manifold. That is the problem. It hits the injectors.

I talked to a guy on DP who used a 6.5 manifold with the same heads I have . He said he had to grind the manifold and the two middle inj line nuts. I don't love that but he was also using long inj so I still don't know if short ones would do it.

I just thought if you got one of them cheap enough, you might be able to use something out of what he had. Maybe Banks will sell you just the manifold?

Aces, I was on ebay a lot today and their are some brand new 6.5 manifold sets. Also a brand new GM set of 6.5 pistons, not that you need pistons, but I'm just mentioning it as I saw a lot of 6.5 parts.

What all OEM-kinda parts do you need? I'll keep my eyes open.

I have Manifolds. My problem is they hit the 6.2 injectors. There was a Banks setup I was bidding on and I f'in missed it by 5 f'in dollars...Went for 480$. I'm feeling pretty postal right now towards eBay...
