I'm keeping my options open. It seems like a 20B is an assload of work, most of which I don't know how to do. I mean, I can figure it out, learn it, etc, but really, it seems like a different swap might be easier.

Don't have pictures yet but dropping a 96 Vortec 4.3 with 4l60E trans. Tons of room, not into massive power, just reliability and enough power to get out of my own way!

Has headers and duals, everything else stock V6

Will post pics when they are ready.

I have also not seen anyone do the 6.0L iron truck LSx motor yet, not in an RX7 anyway. All of the standard LS1 parts should bolt to it, more displacment never hurts

wingsfan

93ls1rx7 is putting a 408 based off the iron block in his drag car (4.030" bore).

Really there's no reason to go with the iron block derivative of the LSx unless you're doing something extreme like Mike is (FI or a huge shot of nitrous). You can make plenty of power NA off of a stock cubed LSx (500+ rwhp), and upwards of 1400rwhp with the right parts on an all aluminum combo (Matt Harlan's TT 'Hawk). You'd be foolish to just swap in the truck motor. Lower performance and extra weight make no sense at all.

hey, how much power can you get out of a 3.8L 6 cylinder from the same Camaro/Firebirds? (Yes, I know you can get a 3.8L grand national engine, but that's not what I'm talking about...)

I'm assuming that you could get close to 300 h.p. with exhaust, cams, heads, etc... And they are everywhere.

Mildly modded LS1/t56 here, planning on adding some cylinder heads and longtube headers later this year.

A LOT.

If you wanted to go that way, you could put in the bottom end from any of the supercharged FWD GM vehicles (Grand Prix GTP, Regal GS, etc) and put a decent sized turbo on it. 500 to the wheels is pretty easily within reach. 6 bolt, crossbolted mains, and rods that have held up to 600+ wheel hp. The L36 top end from the Camaro/Bird bolts up to the other bottom end, and the oilpan/pickup/etc. bolt up to the L67 block as well. I'm making ~400 hp out of mine with just a cam and bolt ons in my GTP. 120K miles, and it's still going strong.

As far as my RX7, it currently has a SBC 355/700r4 in it. That will be coming out this weekend, in favor of an LS1/4L60e from a 98 Z28. Motor will be stock for this summer, then next fall it comes out for heads/cam/torque converter and a few other goodies. Hoping to hit 10's in the car with minor weight reduction. I think that's a reasonable goal.

I was thinking along the same lines... the 3.8 and 5 speed from a Camaro/Firebird and the supercharger from a GTP. Could it be done?

digitalsolo

iTrader: (2)

The 5 speed won't take the torque. (The supercharged cars put out more torque low end then moderately modded LS1 cars, turbo cars aren't far behind, if properly sized) The supercharger from a GTP will face the wrong way, inlet wise (Throttlebody will be at the firewall). Some fabbing, or a supercharger from a Holden (Aussie GM) RWD V6 would do it also. Honestly, I'd go turbo, less work. The L36 (Camaro engine) can take 5-6 PSI without an I/C and probably 10-11 with one. I'd expect 330+ at the wheels with ~10 PSI, I/C'd.

Best case would be using the L67 (GTP) bottom end, and L36 top end, plus a ~.60-68 trim turbo, I'd bet you could hit 450+ at the wheels without losing any daily drivability. L67 bottoms are easy to come by. I've got 3 in my garage. I am president of a larger chapter Grand Prix/Regal club though.

If you have any other questions, or are really seriously thinking about this, drop me a PM or email me @ webmonger@terminalfear.com I've actually considered doing this with another shell once my LS1 car is done. I've got a lot of experience on these engines. I've built one that went 12.8 in a Buick Regal, actually had a 75 shot on it, but we never got to use it (sold the engine). My current car should run mid 12's, and my roommates (also helped build that one) should be 12.7-12.8s. I've got a few engines around too.

Will the 6 speed bolt up to the 3.8? Wouldn't I have to go to lower compression pistons if I wanted to add a turbo or a supercharger and go over 5 pounds of boost?

The GM 3800 Series two (3.8L supercharged) is a great motor.

i put one in a fiero about 5 years ago, and was verrrrrrrrry happy with it.

I'm considering this swap with my FB and was wonderin if anybody makes a cradle or adapter kit for the 3800

Easiest is better

For the guys discussing the 3800 series engines, here are some pics of my gtus recieving an l36/t5. I had to swap the camaro fuel rail for an n/a fwd rail in order to set it back as far as it is, but it's worth the hassle. The longblock itself is behind the front axle center line. If there is enough interest, I can duplicate the motor mounts and transmission crossmember for a fair price.

right now, there is a clusterfook in my engine bay...

SSRx7

Right now, a completely stock 12A that makes less rwt than it does to tighten the lug bolts. A 4bolt main vortec 350 out of a 98 fs van is on the stand getting prepped. Still am trying to decide between 700R4 (readily available and easy to make strong) or a 6spd( desired, but low availability and Big $$$ here). I don't plan on making alot of power, maybe 350 at the crank, but I want something that will start right when I turn the key, won't smell like a flooded engine all the time, and will actually go all day long with no problems. The rotory is fun for what it is, but it isn't fun for what it isn't- and that is reliability. And yes, I know that it is probly my lack of knowledge on rotory engines and their components (ie: piece of junk carb that takes more adjustments than the space shuttle) that make my car not run as well as it could. But I don't want to "have' to work on it all the time. I like to tinker and build, not "Fix".

sorry for ramblin on.
Later,

Not a damned thing.

It HAD a 302/5.0L in it before I got it but was gone before I got to her.

A 10.7:1 406 with WP Sportsman IIs, Victor JR, a cam that looks to be the same size as the 12A rotors that came in the car in 79 A 750 race prepped Holley, a T5 and some other fun stuff will get her around the autocross, down the dragstrip and sliding around the drift events with ease

I put a 1996 Camaro 3.8 auto into a 1st gen. It worked great.
Then I tried a 2002 Camaro 3.8 5 spd into a '88 GTU (both using home grown mounts).
I found that the alternator hit the hood just before it latched.
But more problematic, the throttle body, that sticks staight forward, sticks way out
and is totally unusable as stock. Additionally, part of the intake/throttle body flange is too high. I cut the flange and made an adapter to turn the throttle body upside down. While I could close the hood
I think there was 0 clearance.
I had to move the heater core inlet that is on the driverside of the car.
The shifter for the stock camaro t5 sits just under 2" forward of where the RX7 shifter sat. I roughed out a shift lever that came through the metal floor at the proper position and it worked great.
Next I gave the car away.

If I do it again I will use the intake from the 95-98 or so camaro which has a downturned throttle body. I will use the ECU from the earlier car since the newer cars have "fly by wire" throttle bodies that do not readily bolt to the earlier manifolds.

The 96 3.8 auto in my first gen was a hoot with plenty of tire smoking capability.

Right now I am considering the 3.8 Camaro and the 3.8 from a 99-04 Mustang (among others) for my next swap. Since I think gasoline prices will continue their upward trend for the next several decades I like the potentially better gasoline milage of the V6s - of course at the expense of power - but after a bunch of burnouts etc. how much is enough for street driving!

That SB2 stuff really looks good in that engine bay.
Hmm.
Maybe time to rethink somethings for the next project...
I do know some NASCAR guys, so maybe someone got a old engine lying around...
