brianteel Posted February 15, 2006 Report Share Posted February 15, 2006 if anyone is wondering the motor should bolt right in. there will be wiring and stuff involved but might make for a interesting swap Quote Link to comment Share on other sites More sharing options...

jdcutty Posted February 15, 2006 Report Share Posted February 15, 2006 that would be nifty Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted February 15, 2006 Report Share Posted February 15, 2006 Not to mention you'd have to convert the throttle over to DBW. They never said what tranny it's bolted to. Wonder if it's the standard 65-E or if it's the HD model? Although the 3900 would be a good kick in the pants for my Imp, I still think I'm going the LS4 route, though. Can't go wrong with 303 hp!

brianteel Posted February 15, 2006 Author Report Share Posted February 15, 2006 the only reason i am saying the 3900 is because the mounts look just right....also that compnay on ebay usually sens the pedal so it should not be too bad to figure out....that motor starts with 240 hp....slap a turbo and some tuning and you would have a quick 60 degree motor the LS4 i think is going to be a tough fit. it might just be too wide....need to break out a tape measure Quote Link to comment Share on other sites More sharing options...
ToroToro Posted February 15, 2006 Report Share Posted February 15, 2006 Or you could just use a non DBW TB. I heard a 4.6 Ford one will work... :? I'd be interested in using that intake manifold instead of the 3500 when I do the top end in the spring. Anyone got a pic of one without the shroud covering it up? It looks kinda interestintg.

GutlessSupreme Posted February 15, 2006 Report Share Posted February 15, 2006 I don't understand the big thing with DBW.. I would imagine it'd be easy enough to convert it to a traditional cable setup, or to find another TB that fits. Quote Link to comment Share on other sites More sharing options...
brianteel Posted February 15, 2006 Author Report Share Posted February 15, 2006 the problem with switching the TB is that the PCM is setup for DBW....it should be pretty easy to put in the pedal and 2 or 3 wires Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted February 15, 2006 Report Share Posted February 15, 2006 the other think the DBW does is allow it to control the traction control better by not only pulling back timing, cutting fuel, but it can also cut the throtle until traction is regained (that was the big deal when they were commin' out with it) I think that'd be an awesome swap, and for 3k for the engine/trans/computer you can't really go wrong... --Dave.

jeremy Posted February 15, 2006 Report Share Posted February 15, 2006 a 3900 would be a damn good swap...IMHO of course Quote Link to comment Share on other sites More sharing options...
brianteel Posted February 15, 2006 Author Report Share Posted February 15, 2006 i was thinking...because the motor is also used in the G6 and the w-body cars it should be easy to make a mount for the trans and bolt everything in for it Quote Link to comment Share on other sites More sharing options...

I believe my dad's Volvo has some sort of setup as described....when the TC is working, you could press the gas lighty, or floor it, and nothing will happen until traction is regained.... I like it, and I don't like it. There is a very very short hesitation when you get into it...where you punch it to the floor, and nothing seems to happen, then it kicks down. But yeah, I think that would be a sweet ass swap Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted February 16, 2006 Report Share Posted February 16, 2006 the LS4 i think is going to be a tough fit. it might just be too wide....need to break out a tape measureIt'll probably be tight in a 1st gen, but it should drop right into a 2nd gen. Afterall, the new Impala SS and GP GXP that are available with the LS4 are just re-skinned 2nd gens. No major changes to the platform were made to the new incarnations of the W-Bodies. Hell, the 06 Monte is the same from the firewall back! I'd wait a couple of years for the "bugs" to be worked out of that 3900, though. That whole "cam phasing" and "variable intake" shit sound to me like headaches waiting to happen. And you know that's the main reason that sucker cranks out 240 horses. If it had a "fixed" cam and intake, I'm sure it wouldn't break 210... Quote Link to comment Share on other sites More sharing options...
fastbird232 Posted February 16, 2006 Report Share Posted February 16, 2006 How long until an LS4 is cheap enough for one of us to get stupid enough to drop one in a Gen-1? Question: does it use the 4T65-E? Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted February 16, 2006 Report Share Posted February 16, 2006 65-E HD Quote Link to comment Share on other sites More sharing options...
brianteel Posted February 16, 2006 Author Report Share Posted February 16, 2006 i think it uses a stronger version of the HD trans......well the cost of the one on ebay is lke 3500 for a complete setup with very low miles. it looks to use similar mounts to the 3.4 DOHC motor.....LS4 would be interesting to see Quote Link to comment Share on other sites More sharing options...
Turbocharged400sbc Posted February 16, 2006 Report Share Posted February 16, 2006 actually when i was looking at the 3900 at the auto show it looks like you could swap the T chain cover with the VVT onto a reg 3x00 for a nifty upgrade...also the variable intake would be not neccesary with forced induction or it would only provide a marginal improvment at switchover with forced induction... my curiosity extends to the cylinder heads where with larger valves i'm curious whther it will work with a 3400 bore in which case i see plenty of the 3900 heads being swapped onto 3400's I have a few close high res pics of more than a couple of the engines i saw...just havent thrown them on my photobucket account... from the looks of it though i see it being a fairly straightforward swap...even fer a 1st gen and having to install the DBW throttle...

brianteel Posted March 2, 2006 Author Report Share Posted March 2, 2006 i am sure i can get one of those motors bolted if the money is right Quote Link to comment Share on other sites More sharing options...
92LuminaRS Posted March 3, 2006 Report Share Posted March 3, 2006 That's worth 9X the value of my car! Quote Link to comment Share on other sites More sharing options...
fastbird232 Posted March 3, 2006 Report Share Posted March 3, 2006 Yeah, not really worth it. The best engine I'd ever consider putting in my car would be the L67. Beyond that, I'd just get a new car. Quote Link to comment Share on other sites More sharing options...
OldSkoolGP Posted March 10, 2006 Report Share Posted March 10, 2006 the problem with switching the TB is that the PCM is setup for DBW....it should be pretty easy to put in the pedal and 2 or 3 wires It would be just as easy though to use a 3400 or 3500 computer that didn't use DBW. You don't have to use a 3900 computer just because it's a 3900. Quote Link to comment Share on other sites More sharing options...

OldSkoolGP Posted March 10, 2006 Report Share Posted March 10, 2006 You would, but it would eliminate you having to replace the gas pedal and stuff. Plus you can actually tune a 3400 computer. 3500 I'm not too sure about, but companies like HP Tuners makes tons of software for tuning a 3400 computer.

DiscoStudd Posted March 10, 2006 Report Share Posted March 10, 2006 Do you think they could get the 3400 PCM to control the 3900's VVT? Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted March 10, 2006 Report Share Posted March 10, 2006 Do you think they could get the 3400 PCM to control the 3900's VVT? I don't know much about tuning but it would depend how advanced the 3900's pcm is over a 3400's. Quote Link to comment Share on other sites More sharing options...
