Now imagine that same engine with a tad lower CR with a pair of these $350 SSA manifolds and correctly sized turbos and WG's:

I would think 700whp wouldn't a problem with that setup. Basically a Chris Chow Sy/Ty! I don't know... Just seams an easier way to make more power. I realize you're taking away the Sy/Ty's original V6 platform but I don't see an issue as long as you keep the parts and still can convert it back if you ever want to sell it. Thoughts? Comments?

Been there done that with the LS1 in my 02 Trans Am. Heads arent worth a sh*t when it comes to higher boost levels. The decks are too thin and the head bolts are small and there's fewer bolts holding the head on the engine compared to the SBC. I'm pretty sure the LS2 is the same. You have to upgrade to AFR heads which have a thicker deck. The biggest problem I see with LSX is what they cost. Everything costs twice as much including the heads. I had actually built a LQ8 (6.0) and was going use the AFR's but had to sell it due to finances. Don't get me wrong, the LSX is a great engine and flows like no other but I think the SBC is a better bang for the buck.

There are plenty of 800 - 1000 RWHP Stock type headed LSx's running around. You don't really need much boost to get big hp numbers out of an LS motor if it's built right. I ran a 250 shot for a very long time on a stock LS1 motor without ever lifting a head & I'm sure that my cylinder pressures were way up there. As far as parts costs, you can find LS2 heads which are the same exact heads as the LS6's for around $350 / pair. There are also more & more LSx S-10's running around everyday. Look around in the Hybrids forum on LS1Tech.com, there are a few people making all the swap parts you need to do the swap if you look around. Also AFR heads aren't the only show in town these days for LSx's. There are stock bottom LSx's doing over 500 rwhp with the new Trick flow heads, ETP makes a great set of heads also. All of the big guns are beginning to make LSx heads.

Are they that bad? I see they build a 4.3 too.

A long time ago I have heard some mention to me 'they work but so doesn't the stock parts.' At least with their cheap parts, I also heard from an engine builder they need quite a bit of work to get them to balanced. I thinks its one of those you get what you pay for...

I've been thinking of turbocharging the V8, only problem is finding turbo exhaust manifolds/headers:rant: . Not to mention the plumbing for an IC would be very tight, and very custom.

I've looked at the tt exhaust manifolds from Banks and I think Precision even sells a similar looking set. When we mocked up a v8 tt in my truck it looked like it would fit with no problems. One of the benifits of this style maniolds is they aren't prone to cracking on the street.

Just something else to consider.
