Also, is the gearing the same between the transmissions? or is one shorter than the other?

I'm currently planning out a budget and organizing everything into stages before I start purchasing parts.

thanks in advance

You cannot use the Corvette transmission...your options are the F-body one or the GTO. That GTO is basically an F-body case with the Corvette internals (shorter gearing on everything but 4th and better synchros).

Throw that budget out the window if you want to do it right. You will never be able to plan for everything in my opinion.

I'm currently putting an LS6 into an FD for a buddy of mine and we tried to budget even after I told him it was impossible.

Even though I had just finished mine, there was no way to remember all the little things that would be necessary. Even after giving a "Misc." amount of approximately $500, we went way over because I refuse to do it half ***.

Is there a "preferred" year or model? How about the truck motors? What "donor" vehicles should people be looking for?

However, truck engines are very cheap and are a good way to cut costs if you don't mind the hassle of tracking down a manual tranny (if that's what you want), the F-body accessories, LS intake manifold, etc.

Hopefully the list below will help in the search for the right engine for your project....

GENERATION III - I recommend sticking with the Gen III engines due to the large production#s and the resulting cost effectiveness.

LS1 - 5.7 (346 CI) - Between 305-350 hp and 335-375 ft·lb
1997-2004 Chevrolet Corvette C5, excluding Z06
1998-2002 Chevrolet Camaro Z28, SS
1998-2002 Pontiac Firebird Formula, Trans Am, Trans Am WS6
2004 Pontiac GTO
*97-98 Had Perimeter Bolt Valve Covers

LS6 - 5.7 (346 CI) - 385(01 Vette only)/405 hp and 385(01 only)/400 ft-lbs.
2001-2004 Chevrolet Corvette C5 Z06
2004-2005 Cadillac CTS V-Series

*Basically the same as an LS1 but with better heads (243 head castings) a more aggressive cam, and LS6 intake manifold make up the power differences.

TRUCK ENGINES - STILL GENERATION III - 285-295 hp and 325-335 ft·lb

The truck engines are very much like the LS1/LS6 and are still classified as a Gen III engine. They are mainly iron with the exception of the LM4/L33, and as a result weigh approximately 80+ lbs. more. All the parts from the LS series can bolt on to these engines and is recommended for any swap as the accessories and intake manifold usually fit better from an F-body. The 4.8 and 5.3 can both be punched out to a 5.7 (346 Cubic Inches) simply with a bigger bore (the 5.3) or a bigger bore and the 5.3 crank (in the 4.8's case).

4.8 - LR4
5.3 - LM4, LM7, L33, L59

Question: can all of these use the same mounts? and all bolt up to an F-body or GTO 6 spd tranny?

Well, it really wasn't a budget as much as it was a parts list so I can put myself in the general area of how much i'll need for the basics. it's basically to tell me how much time i will be spending saving and allowing me to budget work time and project time accordingly. of course I know that's not including all of the extra nonsense that comes with hybridizations such as this one.

My project is a "cost is no problem" type...just time.

Anyone know of any good write ups or manuals for the LSx swap? I mean, I'm sure my buddy and I can do it on our own but a write up or some measurements will make this thing all that much easier. Anyone have any experience with Adlashwa's manual?

Also, how hard would it be to run some Ram Air with an LS1 in a 300Z? the LS1 has that nifty forward facing throttle body and you can get those slotted nose panels...I would think one could use a modified version of the F-body ram air box with an F-body filter and mount it up behind that nose panel, right?

Yeah, I'll sticky it for sure....took me a little while to put it together.

All the RWD ones should have the same mounts but I can't guarantee that. Obviously, I would avoid the FWD versions (although you can probably use the heads).

They should all bolt up to the F-body and GTO transmissions...the Corvette one is something you will NOT want to attempt.

There are too many variables (cost of your pullout can differ greatly) for me to give you an accurate amount to budget. Do you want an aluminum or iron block, standalone or not, driveshaft material, mods, etc? I would say $5000 will be a good starting point to get your pullout purchased and most of your major items. Everyone is different so I don't know how anal you're going to be in doing your swap.

I'll try to get up a sticky in the near future of my swap. In the meantime, hit me up on AIM: midcnichols with any questions you have or search here in the Hybrid forum.

Ram air is worthless for the trouble you'll have to go to due to the radiator and low profile front of the 240. Just build a nice cold air intake with at least 3.5" piping and you'll be good to go. If you want to get fancy, build a Y pipe and have dual 3" piping going to each side of the bay.

If I had a 240SX, I'd be looking at either a VH45 or a 2JZ. Probably the VH45. I LOVE that motor but there's no aftermarket for it...otherwise it would be perfect (aside from no 6 speed...which I want just for kicks and giggles).

btw, you are getting added to AIM, my screen name is Messiahs Oracle, so if you see that name message ya, that's me. thanks a ton.

thanks again, you've been a great help

if you want you can shoot me an email, that would be much appreciated.

05 GSX-R 600 - CF Gas Cover, CF Triple Tree Cover, CF Gauge Cluster Cover, CF Tank Slapper, CF Yoshimura TRS Exhaust, Removed Graphics from Tail, Suzuki No-Cut Frame Sliders, Suzuki Swingarm Spools, HotBodies Undertail, Pirelli Dragon SuperCorsas, Sportech Red Chrome Wind Screen

I got everything in multiple for the chevy so thats where the real sell point is also the wieght vs a rb25det would be good.

Not to mention the Trans Ams and Monte Carlo SS (ya i like mullet mobiles too)
