3300 Engine Swap Help?????

[L.B.R.MotorSpor]

Just got another Grand am gt. It's a 93 with a 3300. Now i want to put a 3400 in it. I have read so how toos. For the 3100, is it all the same or things different??? Also might be looking to do a 5 speed swap what tranning will bolt up to the 3400 ??? Thanks for the help

[Matt95GT]

Engine and trans mounts will be an issue... that will require welding new ones on. It might require having a donor car to cut them off of.

[L.B.R.MotorSpor]

can i just change the mounts and keep the tran then??? Don't do the 5 speed swap. So will the trans bolt up to the 3400???

[Matt95GT]

Well, additionally you'll need the complete engine wiring harness and PCM. That PCM can only control the trans that it was originally mated to. In other words, you can't really mix and match... gotta use 1 complete engine/trans/PCM/wiring harness - which will still be a large undertaking.

As far as the details on the mounts, you'll need to research this beforehand - I don't think anyone here has the exact details on them.

well want the bigger enigne and only paid 300 for the car so spending alittel on it wont hurt. But i can use a 3100 trans and computer out of a 95 grand am and just buy the 3400 somewhere eles . That all works , i am right ??

Its still not worth it. Just either boost the 3300 or buy a different car.

[L.B.R.MotorSpor]

people said the saem thing about my turbo neon. that it wasn't worth doing something like that too. But it will run 12's now and was well worth it. Just want something for school next year that will last a couple years with no problem

[1992grandam]

Yes and I can understand a neon and boosting it but thsi is different. You will seriously be better off just boosting the 3300. If it was a 3100 then the swap would be easy and worth it but the 3300 is completely different.

Yes, you can do that, however note unless you get the ECM reprogrammed or modified, you have to use injectors from the L82 3100 engine. If you use the injectors that are on the 3400 the engine won't run properly--it'll be too rich. Note that LG8 3100 injectors will be the same, so be sure to get L82 injectors unless you are going to get the ECM modded for the injectors on the 3400.

the 3300 is a nice motor. wouldn't trade for anything, well maybe a 3800 SC motor out of a GTP... but. the biggest draw on the car is the tranny. 3 gears aint enough. personally, i'd say swap in a 4spd. unit from an A body car. OR, swap in a 5spd, using parts from manny tranny G/A and a tranny from a V6 beretta or W car. and somehow fool the puter into thinking its all there.

The 3.3 is 'Extinct'

Trade your '93 in for a '94, and take'r from there.

Or just try looking for a Quad 4 (same year, before, and after)

Isn't the 3300 the little brother of the 3800? That swap might be a little easier. The forum admin (Jamz) on gmperformancetuning.com has a 93 with the 3800SC.

True, but he spent years and thousands to get it running right. Quite honestly, there is no "easy" swap on a 3300 equiped GA.

[Mike94SE]

Hmmm...

-Would you be interested in trading the car?
-Is a 4 cylinder a problem for you?

Matt's got one for sale :P

physically speaking, yeah they are cousins. more like distant cousins, kinda like the hot ones that are married in.... anyway....
GM changed the fron half of the engine in how the accesories are mounted, thus negating the bracket used on the G/A for the 3300. i dont have the money to pick up a series1 3800 from the yard and a spare engine mount for the front (G/A) and actually see if it works. also, has anyone thought of swapping the accesory mounting stuff from the 3.3 G/A to a 3.8?

[goredsox]

first off anyone who thinks the 3300 is dated, old, dead, or "EXTINCT..." should watch their mouth. granted the 3300 isnt the best motor out their she is great in the GA, more than enough grunt at lower speeds and the fact that she is related to the 3800 makes her an even greater engine. true the 3 speed isnt the greatest, it serves well, plus no other tranny that i know of will bolt on. Just beef up the 3300, dont swap. CAI, Custom Exhaust...

There is in a way if you use a series I 3800 89-90 that 3800 is almost Identicall in everyway as in sensors and placement. As for a 3400 in a 3300 GA not happening without changing just about everything, wiring is mostly the problem since the 3300 is OBD I and the 3100/3400 engines are OBD-II there are different sensors that have to be accounted for that help those engines run, if you want bigger go with a 3800, but like we all have said time and time again upgrade the tranny to a 4 speed use a 4T60 not 4T60e( Computer Controlled ), anyway you need the axles and mount from a 94 and wire the TCC connector to work with the 4 spd and your golden. There has been some that have installed Manual trannys, but have found that the you'll need to have a custom flywheel made and some mount modding. But you can use most of the other parts from a manual equiped GA. Also yes the 4T60 and the Muncie 5spd will bolt to the 3300 direct.

Feel free to contact me for any others questions on the 3300
