It'* been done a couple times. But you're limiting yourself out of the box with the weaker bottom end.

I'm not positive the heads will bolt up.

Doesn't matter. You'd be a fool to try to keep the LN3 top end when you could just start with an L67 to begin with since you need the bottom end anyway. Use the empty SC housing with a blankoff plate for your manifold.

Ummm.....yes, you'll need to tune.

Sounds to me you don't really know what you're getting into. The turbo itself is going to run you $2k MINIMUM in the car. That'* just the turbo, manifolds, piping, intercooler, etc.

Another 2k for the trans. Plus a different motor to start with, tuning, etc.

The L27 Heads will bolt to the LN3 Block and the LN3 heads will bolt to the L27 Block..

well, i've already got the turbo, intercooler and transmission. i'm not worried about the transmission or the turbo or the exhaust, i've already got what i need as of that far. I was just wondering what i'd have to do to the engine. I don't really wanna have to buy a new engine block unless i really have to. i can find the parts of other engines if i need to unless it'* cheaper just to get another engine.
I am trying to go the cheapest route i can and since i already have a turbo "kit" i figured that that'd be the cheapest way to go.
if there'* a better way to go though, call me out on it.

Get the L67 bottom end. It'* the easiest, most cost-effective, and reliable way to start.

Tell us more about your transmission and what'* been done to it.

On this one I do agree with Willwren... Your best bet is to find an L67 as it was already designed for Boost.. It would be cheaper than trying to build one..

And these transmissions won't handle a lot unless they are somewhat built

alright, thanks for the advice everyone, it'* greatly appreciated.
For those who are wondering about the tranny, it'* gonna be a rwd application, it came from an old camaro with a 305 in it. it has a transmission cooler in it too. I'm sure I'll be able to get it all in the car i'm gonna be working on (I know pretty good people). I'll probably post some pictures of it towards the end of the summer if i'm finished by then.
