3.8 motor?

[h_bodyfreek]

ok i want to know if a 3.8 supercharged from a gtp grand prix will fit into a 96 grand am gt sedan originally 3100?

[Brandon]

fit? yes?
lots of work? prob.
how bad do you want it?

[h_bodyfreek]

well put it this way my 3100 has a blown lim gasket i need a new ac compressor and a piece of porclein fell into engine when replacing cracked plug <which is goign to cause sever damage sooner or later> and besides i can get a motor complete ready to drop in for like 650 US and the computer and mounts and everything else for under 300 so for about 1000 give or take and around 10 hours of playing around i could blow the doors off and gtp and make em look pathetic

[Brandon]

i dont think the mounts will line up, but ill let the others talk about that since im not to sure... and 10 hours? i swear ive heard a couple more then just 10. if it were a simple 10 hour process, i think many many many more of us would have it..

also, im taking a guess but i think your tranny will need a sprucing up to take it.. but i could be wrong on that too.

stock gtp engine will only make 240 hp. its not really going to blow the doors off you'll win, but not a blow off.

[h_bodyfreek]

no buddy the 96 grand am gt is like 1000 pounds lighter than a gtp is so i'll blow his doors off. and the mounts wont line up but thats where metal fabrication comes in handy and yeah ten hours would do it. Tranny not so sure though

Swapping the 3800 motor into your Grand Am would be a waste of time.

Swapping in a slightly build up 3400 would take a fraction of the time...and if you really want to do some fabrication and be different...install a 5-speed aswell.

[h_bodyfreek]

why would the 3800 be a waste of time it has more horsepower than the 3400 and to top it its got a supercharger with 10 psi so it would not be a waste of time

[slowbird]

The amount of time you spend:
- Making it fit
- Making it run right
- Making Mounts that won't break
- Re-wiring Sensors/ECU junk
...and other things I can't think of...

A 3400 would replace the 3100 nicely. You can do some slight mods to it...and won't take a fraction of the time. It would be great.
You can put a charger on the 3400...and if you have an OBDI in your Grand Am (I didn't see what year your GA is) Dropping in a 5-speed would take a weekend.

A stock 3400 in a Grand Am with a 5-speed would be in the 14's.
With Slight mods you'd be in mid to low 14's.
...and with mods like Xonelith has...you'd be running mid 13's easily....and not have to worry about tranny issues.

Not this question again??? :roll2:

[Brandon]

mantagreen97, its only a 10 hour swap though!

The way I figure it, if you REALLY want it, it can be done. you just need to know welding, fabrication, and have the tools, parts and time. IF you can stuff a 460CI engine into a pinto, you can fit this without much trouble I think. probably a different tranny and maybe some other minor stuff and you'd be on the road pretty quick.

This is just how I figure, but I'm frequently wrong.

i believe i saw a guide for the tranny swap before.. and there is a guide for the 3400 swap. http://www.3400swap.com the quide is extremely helpful.

[h_bodyfreek]

ok guys none of u are getting it. a 3400 has more problems with LIM than any other cars ive seen before and a 3800 dont and yes ten hours a new tranny which i already got from a junk gtp would fit and ecm and all the wiring harnesses are no big deal i know someone that dropped a gtp engine into a 2002 ga gt without any issues he is going to help me do this and then i'll send ya'll some sweet ass photos of my car with a 3800 with a supercharger in it.So the 3400 swap is outta range . Besides there is not much difference between a 3100 and 3400 in power.

As you can see, lots of talk, but no real results. Most people that have to ask about such a swap never actually do it.

[slowbird]

You sound like you really want to do the 3800...that's fine...you are commited to it it seems.

I have seen plenty of Supercharged, Turbo, and Crazy N/A 3400 make great times. Yea...a 3100 doesn't have that much less power than a 3400...but the 3400 has more potential through Intake and Head port sizes. The LIM issue can be fixed by simply installing the new revised Gasket. (if you are swapping in a motor you should be changing the Gaskets while it's out anyways)

I was never a fan of the L67

[h_bodyfreek]

thats fine and dandy but ya know how many mods are out there for the gtp engine? Between whats its got and what i can do to it , i will end up smokin vettes by th e time im done with it.ford wont stand a chance

I know it's always the exact same thing. Starts out as "Can a 3800 fit in a GA?" Then the appropriate responses are given.

Then person asking the question says "okay whatever, just wait I'll have an L67 in my car in 10hrs" :roll2: "and then you'll see!" Right I'm still waiting for the pics from 50 other ppl that have said it before and gone nowhere. Well the 10hrs thing was added in this one, so at least that's new hahaha.

But seriously it's not that I doubt you in particular, just look at how many times the exact same thing has been said and never has it been done.

It's just tiring to read the same thing over and over.

It is possible with time and money (and a lot of both at that), it's just that there's been what now one or two 3800s that have ever made it into a GA (of any year)? And those couple of ppl that did it will definitely tell you it took a LOT longer than 10hrs.

You'll still have a '96 GA, $2100 retail Blue Book

With the world's WORST brakes for a modern car of its size/pretentions, adequate-but-not-excellent suspension, reliability that barely exceeds a Yugo, and a chassis with significant stiffness issues (which were greatly improved in the '99+ chassis).

Finally, the joy of driving IMHO is the combination of handling, braking, and acceleration.
Flat-out acceleration is for wussies, and drag times are just one factor of a great car.
Fact is, a car of our 's weight, IN FWD, can't handle much more than 225 hp as a road car.

More than 300 hp, whether by displacement, super/turbo charging, or NOS, is wasted, since weight transfer will prevent the excess hp/torque from getting to the pavement.

But that's just my opinion, more power to you!!

I think you should just get a camaro or ta and leave the grand am alone.

You'll have issues with mounts, traction, and the fact that you have a boat anchor as an engine in the front of your car.

Meanwhile...Xonelith will be walking by you in his Daily driver :P

[h_bodyfreek]

ok well i have come to a conclusion. screw the new engine with a 3800,im gonna put in a new 3100 ans buy myself a trans am ram air thats been heavily modified puttin out almost 550 hp and still have my grand am

Yea....exactly. :lol:

[Brandon]

if its only a 10 hour deal, why not go for it and still have a ta as a side car?

[h_bodyfreek]

because with the condition my ga is in i figured it out and it wouldnt be worth it to put all the money i wanted to put into it . my airbags are screwed and the floor leaks and my windshield leaks somewhat and the power windows are screwed and obviously my motor

[Brandon]

oh! ok buddy!
