I have a question for you guys, Can you put the 6 cyl engine from the 3000gt vr-4 into a 97 gsx ? things you think about when you bored... Imagine that shit starting off at 320 hp that would be some crazzzzy shizzle LOL get back to me on this before I get too bored.
 
Yes, but you have to be careful in closing the hatch because it tends to stick up further than you think, and you'll bust that glass out before you know it. Also, if not firmly tied down, it'll roll around back there and bash the living shit out of the surprisingly flimsy plastic trim in the cargo space.

LOL

i think if he laid the back seats down and put it in horizontally it would fit nice, but there is a greater risk of leaking fluid in the car, and then it would be in the cockpit
 
ahh if you put it horizontaly that you would have oil in the wrong place. if you want to make your AWD a RWD it's posible (I'm not sure if there is such thing as fwd 3000gt) just take a fwd tranny and hook it up to your rear wheels. You should have enough clearance once you lower the engine to the wheel level, but again it's a waste of money, LOL
 
aight you guys are little shits LOL. Well I ask this because my friend smashed the vr-4 and gave me the engine and tranny, I thought it would be pretty sick. I'm pretty good with custom fab, last one I did was a 454 into a 240Z. Probably the fastest car I've been in so far. Let me know if someone knows the REAL answer, and no i dont want to put it in my trunk.. shit heads LOL that def was funny though
 
I am sure if you were the first person to ask this, you would get tons of responses. Since you are like the 301st person to ask this, the answer pool is empty.
 
The answer is this: No, it cant be done, there simply isnt enough space. But, people with way too much money have been known to do things that "cant be done"...

Anyways, why would you use the 3kGT motor over our 4g63? The 4g63 is obviously a better motor to work from, regardless of how much horsepower they come with stock...
 
Some people just jump to a conclusions way too quick!!!! :thumbdown:

Well, let's see if this helps. Let's be more methodical in this. As impossible as this seems, there are components on the 3000gt plateform that are nearly identical (or are) to those on the eclipse.

My first impression it that, yes, it can be done. Here’s why:

Look at packaging of the 3G, they package the 3.0L in the same space as the 2.4L and the 2.0L. Sharing common mounting locations for tran smounts, engine mounts. Length of the engine is common, because they share similar transmissions. The length of half-shafts are also common, backing the idea that the engine block and trans dimensions are common. (or close enough that the tolerance difference can be absorbed by the half-shafts). Ever notice how the transmount 1G to 2G to 3G all look real similar? How about engine mounts? How about the location and shape of the body bracket that the drivers side engine mount attaches too…….. Interesting?

Issues I see:

1. The obvious, front to rear packaging. Easy. Find yourself a 3000gt to measure. Measure firewall to radiator. Measure centerline of engine to radiator and centerline of engine to firewall. Compare that to your 2G. Crawl under the car and take some measurements relating the dash panel to the front suspension cross-member. You can then relate those to the motor. How about the centerline of the axles to the cross-member? Again compare to the 2G.

2. If those dimensions are very similar, you’ve got something here. Now, some of the transmissions are identical with the exception of the engine side trans case. Some similar internals, some different, to account for gear ratios changes. Applies to 5spds and autos. (if you doubt me, check the part numbers) The 2gen 3000gt’s with 6 spds are another story. Based on that, the trans mounts, should be identical or nearly, allowing interchangeability. The axles should interchange.

3. The TT version of the 3.0L may cause issues with the dash side turbo interfering with the front crossmember. Thus, this is where measurements are important. It’d be nip and tuck. Exhaust may cause issues.

4. The radiator may need to be relocated forward of it’s current location. Moutning it where you would mount a front mount. That’s easy.

5. You’ll need to utilize the 3000gt tranny because of the difference in block bolt pattern.

6. Wiring harness and ECU.

7. Just do it. Got a parts car setting around you were going to take to the salvage yard? You already have the engine tranny, right? So, set it in place see how it packages. Until it's tried, you can't say it can't be done.
 
Not quite. The 3G is whole different bag of chips because of the orientation. The guys who have done Evo motor swaps into 8G Galants have proven that a tranny meant for a 4Gxx motor will only bolt to a 4GXX motor. a tranny for a 6GXX motor will only bolt to a, you guess it, 6GXX motor. So you are going to have find a way to get the AWD to work with the 3KGT tranny and fit the axles and get custom drive shafts, or convert to FWD and put an SL tranny under there.

Either way, you'll have a money pit of a science project of a car and would probably be happier keeping your GSX like it is, selling the VR-4 motor for mod money, or sending it out for being built up while searching for a 3000 donor car and have two streetable rides.

PS. I can't see comparing a SOHC NA 3G v6 to a DOHCTT 3000GT motor. Packaging would still be an issue.

1. If you read in my reply, number 5? Pertaining to engine/tranny bolt patterns. Thus, if he has the 3000gt AWD tranny.... not an issue. If not, he can buy one of my adapters in 5 months. Axles, reuse the ones from the GSX.

2. True. Potentially costly. But if he has the parts sitting around....... why not. Start and see where it goes.

3. Do you think the 3.0L engine is new? Difference? heads are dimensionally wider. Block is the same, TT to NT. With the exception of oil squirters and pistons. Similar to a 2.0L T to NT. Let someone measure it and THEN tell us it won't package. Be a little more positive.

Won't work...... Someone probably said that to Buschur once, and look where he is at.

Anyone else notice how everytime someone asks this question defiants answer gets more detailed.

Well, then. Hold the phone. If you're fairly apt at building this kind of thing -even thought the V-8 into a Z is kind of common (okay, with 350s, but still)- you may be able to pull it off. I don't know the specifics of that motor, nor how closely things like output shafts and shifter linkages line up, but if anyone could do it, at least you have some history at it. Most of the time when this question comes up, it's from someone who's found out they can put a GREDDY oil cap on the top of the motor, all by themselves!

They're not nearly so good-humored about being ribbed, either.

:laugh:
 
Aight thanks you guys morphius is the shit btw thank you for your knowledge. I just thought it would be Different and fun to hae 325 stock mean no hassels. If you have a dsm you know there are hassels and things breaking once in awhile.. So you are all right it can't be done unless i rip apart my firewall and shit so ill just get a 6 bolt engine instead. Anyone want a 3000gt vr4 engine LOL offers wanted haha anyways heres my new idea. 6 bolt, ross pistons, eagle rods, arp studs, port and polish 8 hrs. web cams and a 20g possibly Green turbo. Where should i stand for hp at the wheels maybe 400 ??? i figure ill be saving weight and time not money but by the time i sell the vr4 engine i should get maybe 1500 for it. Let me know what you guys think is a good idea for pistons and rods. I need the car to be pretty reliable because it's my winter car/summer car and in ct it has already began to be winter.. Thanks again for all your responses even the smart asses i enjoy a good laugh.
 
hey morphius btw I see that you put a 455 in the talon well how about this i rip on you a little LOL. Olds common man thats not muscle that crap LOL I have a 454 ls6 i can sell you. 550 hp 600 lbs or torque. If you want REAL american muscle let me know LOL.
Just playin with you possibly you would rather chevy(cheaper,more parts,more power blah blah) I also has an old supercharger i think its an 871 or 8 something i cant remember oh and a ton of holley 650 and 750 carbs. Let me know

The 455 is a 1970 SF code Buick. More rare and most desirable of buick blocks. 1970 was the pinnacle of power for most of GM. I would have gladly taken a 454, better yet a LS6 454. But, they are a bit scarce here in metro detroit. Old school power is rare period. The Buick would run hand in hand with the Chevy, Pontiac, or Oldsmobile. I ran a 454 in my cutluss back home. It had an open diff, 2.41 gears and still enough torque to pull it to mid 13's, 100+ . And you can make a open diff g-body hook, need the right sized tires, some weight in strategic places. Oh, I miss that car.... you could run first gear to 65+, never really shifting in a street run. Top it off it was tucked in a pewter gray, four door wearing stock tires and wheels. No mods to the hood. Hidden, quiet exhaust. Big sleeper. Suprised alot of people.

A drag racer from Ohio had the 455. Couldn't pass it up. Fresh, 0 mile rebuild. Bored over and cammed. Came with a fresh tranny. All for $1500. Not bad. Then consider, I bought the GSX for $50 and tuned the motor and resold it for $800. So, to start off I've got $750 into the car. I'd estimate the total bill to be around $2000. I'd estimate it weighs around 3400 lbs and given the HP, theroetically will run mid 11's, if I can get it too hook. I agree the Chevy has better part sources, but oh well.

I love DSM's. I'm definately addicted. The power attainable from the 4G63 is truly remarkable. But I found I yearned for the brute torque of old. Thus, my project.

So, how much are you asking on the VR4 engine/tranny? Miles? How complete is the motor? Turbos, sensors, harness,etc.

What is your zip? Would you crate it and ship?

That transplant is very intreguing for me. I'd love to do that swap, just to show it can be done. I'd also thought of putting an AWD VR4 or GSX powetrain in a Willys Jeep Pickup for a fast parts hauler. Hmmm..... too many ideas and projects never enough time.....
 
Go out and buy a diamante and put the 3000gt motor in there.

Would be alot easier and i think alot more fun.

now that is a good idea, i think the only good reason to do a crazy swap like this is to make a sleeper, and a tt diamante would be a SLEEPER

but if ur stuck on the eclipse i think your silly but good luck

Won't work...... Someone probably said that to Buschur once, and look where he is at.

I didn't say that it wouldn't work, I just said packaging would be an issue. I hardly compare stuffing this engine into a street car compares to what David Buschur is doing with the 4G63, but again I never said it wouldn't work, just probably more expense and time that this guy is looking for in his street car. The 4G63 has so much R&D behind it, it just doesn't make sense to dump it for something that is heavier, costlier to fix and takes much more investment for the same (or less) power potential. You hardly see Supra guys trying to stuff Tundra V8's into their MKiV's. Skyline guys in Japan aren't looking for Infiniti Q45's (or whatever the hell they're called over there) in the boneyards for swaps. So if he really wants it, it could happen, I just think it would be pointless unless he just wants to say "I did it, I'm cool." But since he said it would be great starting off with 320 instead of 210, the cost of the swap would far outweigh getting a 4G63 to 320. The 6G72TT just doesn't quite have the marketing support to make it a viable swap IMO.

Go out and buy a diamante and put the 3000gt motor in there.

I agree, better yet how about a Diamante wagon.
 
According to my friend that works at mitsubishi it wouldnt be that hard at all. I just picked up a diamante for my winter car and noticed it had the same motor as the 3000gt nt.

It would be fairly easy to slap the turbo engine in there. Only problem would getting the nt fwd tranny to hold up.

Or i guess you could weld the center diff on an awd tranny and not have the transfer case connected to anything.
 
the NT FWD tranny is identical (inside) to the turbo FWD DSM tranny. Since there are more than a few FWD DSMs with huge HP, Im sure that it could handle a VR-4 motor attached to it. Problem is, I dont think the NT tranny bolts to the VR-4 tranny.

So yeah, basically you'd probably have to do the welded diff thing and run FWD....

I've got a friend that has a 3000GT base model with a VR-4 motor swap. Hes running FWD also, this thing is a highway monster :D ...
 
Hey Morphius my friend offered 1400 to me, the engine is in full i have everything ECU, axles,turbos, EVERYTHING. I believe the rear axles is shot because it broke in half LOL. The engine it self has 65k on it with the turbos are rebuild at 45 k. If your interested let me know, for shipping I wouldn't want to know the bill to send that engine out. zip code 06025 Glastonbury Connecticut. So I dont know where you are from, anyways any ideas guys on the pistons,rods ect. I think i have a pretty good idea but maybe im wrong let me know.
