Don't Flame Me

[1fast97gsx]

I have a 1997 gsx and never looked into the non turbo world. I just got a 1995 non turbo talon and of course want to do a turbo swap.

Now I know generally this "can't be done", but I'm just wondering why not? Is it that the motor mounts are all totally different, or just the fact that turbo engine, trans, ecu, wiring harnes, and axles would be needed and it would just not be worth it? If that's the case then I have all that stuff laying around beisdes the wiring harness but that shouldn't be too hard to get.

I don't mean to sound like a newbie but like I said I don't know anything about the non turbos and I've never even payed attention when I looked under the hood. I just have an "extra" 4g63 from the gsx and also a gsx trans laying around I could throw in as well as my stock gsx ecu. Thanks.

anything can be done with the right amount of time and money. aside from that, i cant help cause im a complete n00b.

 

[Slow420a]

uhh you cant swap a 4g63 motor into a 420a eclipse, it wont work, well it may but youll be the first if ya wanna tackle that, you can get a turbo kit from hahn or star, or just make your own custom kit

 

[Defiant]

It's also different sheet metal on the inner fenders. I don't know to what extent that gets in the way of the ghost swap.

 

[SnoopySLR]

I just got the Star Stage 2 turbo, I love it! I've seen 4g63 swaps done, but I've heard they're more trouble than its worth.

 

[Gorkoracing]

Yep get a star or hahn turbo kit if you want it boosted. 4g swaps are gonna end up costing more than what you'd pay if you turbod the 420a and built the internals.

hey, welcome to the n/t world! To answer your original question, add this onto what Defiant said, although the cars look exactly the same the engine bay is a little different, you will have to fabricate your own motor mounts etc. Its such a PAI and will cost you endless amount. For Example:

4g63 Engine: $1500 (6 bolt w/ 510cc injectors, big 16g turbo)
ECU: I dont really know im just going to say $500
Transmission: $1000 (again i'm not really sure)
thats umm $3000, Now if you do it yourself you will waste endless amount of time tryin to fab mounts.

Now you could do this:
Forged Pistson $400
Forged Rods $300
Star or Hahn Turbo Kit w/ FMIC $ 2600 (you might get it for less if you wait on it and keep searching for a good deal or a group buy)
So thats $3300, [cough turn up the boost bish cough] well even with 10psi (you have forged internals so no worries ) you would spank the shit out of a stock 4g63

Please no one turn this into a 4g63 vs 420a war, both engines have their advantages and disadvantages in their own ways, and i will recomend this thread to be locked if it becomes that "type" of thread sooo....lets have a good old family discussion shall we :laugh:

 

[97gssleeper]

I've heard of it being done. Motor mounts are a custom job. Shouldn't be as expensive as everyone else thinks since you have most of the parts already.

 

[miamieclipse]

can i ask a question then? Why did you purchase a n/t if you want the 4g63?

I'm not flamin or anything, just curious

I have a fully built 1997 gsx with forged internals and an sc61 turbo ... bought this as a daily driver because I got a GREAT deal on it but the lack of power kills me

 

[1fast97gsx]

To add to that ...

I have a 6 bolt block at my house with 1g rods and 2g pistons as well as a ported 1g head to go on it. local junkyards carry millions of fwd 1g trannies ( not so many 2g ) and I still have my stock ecu as well ... seems like I wouldn't really need a lot of actual parts, the wohle motor mount thing is what I was confused about. I didn't realize how totally different the nt mounts are from the turbo.

This may be another repetitive question .. but whats the fastest NA dsm so far run? I'm not really a fan of all motor 4 bangers, but since the 4g63 swap won't be worth it then maybe some high compression pistons, stronger rods, and so on are in order. I'm sure a rebuild wouldnt hurt the 128k mile old 420A one bit.

never thought of doin a swap, but it would be pretty interestin. i think it would be tons of work, headaches, and MONEY, but in the end u could end up w/ a car that has all the performance of a gsx but w/ the weight of an rs. if u have the money then do it. but i personally wouldnt cuz i dont waste money for fun.

 

[miamieclipse]

cool, well you already have a turbo car...imho i would just do some basic mods on this one because it is your daily driver [unless your set for a turbo kit/nitrous then go to it ]

Cold-Air Intake, Header, Hi-Flow Cat, Cat-Back, udp, p&p intake manifold, bored tb, ground wire kit, cam gears, afc. Our stock heads flow pretty well, and if after these mods you still want faster you might want to think about the bottle

If you are going to go turbo, get the mods listed above except, header & cai (you will not use them when you go turbo) and if you get a custom exhust or aftermarket make sure it is 2.5" piping because you dont want to get 2.25" and then have to change if you decide to turbo down the road.

Some turbo kits you might want to check on is www.hahnracecraft.com or www.overboost.com

Good luck, keep us posted.

 

[1fast97gsx]

ok thanks for the info. Car has some ebay intake on it already and a custom 2.5" catback. I'll probably just put a header on it and do some porting and polishing and leave it at that for now. Hmm ... I do have an safc and a nitrous kit I could put on

 

[miamieclipse]

hey r u just stealing mods off my sig? not cool :thumbdown :laugh: hehe

Yea get a cai off ebay (make sure its 3" piping) then go to pepboys or some auto parts store and get a nice k&n air filter (the ebay intakes filters aren't very good). Get a nice header and a hi-flow cat and you will be looking very nice.....you will be running rich so a safc would be nice oh and dont forget an udp, you can get it from howell $150 shipped, it dosent create hp necesarily but it frees up some extra power (noticebale, best mod cost wise for the n/t imo...well other than nitrous).

If you do get nitrous dont take it over 75 (wet), get some ngk copper one range colder plugs...oh some msd wires, dont really make a diff w/ nitrous BUT it smoothens out your idle

IM me if you wnat some more info, mnf155....i might be ghosting so just try and IM me, i'll tell you why later, stupid stalker chick

all the BS about 4G swaps... it doesn't work. Soem guy spent $7,000 on a 4G swap and while he could (in theory) drive around it still ran like shit even after a fortune and a half was spent on it. The motors sit on complete opposite sides of the engine bay. The wiring is not at all compatible (the 4G is a mass air flow motor, the 420A is not). The transmission is not compatible (expensive custom stuff and some serious MacGuyver work would make it work).
Just turbo the 420A... or do the 2.4 liter swap and turbo that. Get a Caravan/Cirrus/Stratus block, put in SRT-4 pistons and rods (which you can get for very very cheap), and then you can get at least 500whp on a motor that would cost have as much as the 4G.

I know you can't swap in just the block ... the original question was if I were to look inside an empty 2g turbo engine bay and then an empty 2g non turbo would they look the same as far as the motor mounts. I have a 1g motor, trans, 2g ecu, 1g axles, so all I would need is the wiring harness. The question was if it would physically bolt in or if new mounts would have to be made. I read now I would need new mounts, however a guy on here did it and it cost him around $3500. Thanks for the help though.

 

[leakyfaucet]

(the 4G is a mass air flow motor, the 420A is not)

Then what is the 420A? Don't tell me it's a speed density meter. That seriously some outdated technology. :laugh:

I said I would swap the 4g63 ECU and wiring as well .... SO EVERYTHING ... what does the airflow meter have to do with it then????

 

[halfmazin1]

i was wondering the same thing on the swap it alot of fabrications costs to much holdon i have a link on where i was given pictures it will help explain alot http://www.dsmtuners.com/forums/showthread.php?t=134570

 

[1fast97gsx]

hmm almost seems just as easy to swap in an LT1 now

This may be another repetitive question .. but whats the fastest NA dsm so far run?

I'm sure a rebuild wouldnt hurt the 128k mile old 420A one bit.

Since no one really mentioned this, the fastest NA time is a 14.6 et. The guy who ran it had built up everything (some was sort of proprietary and he wouldn't give me details), but the kicker was that he hacked his tranny and changed the gearing, which helped immensely. That car is parted out and gone now, which makes the fastest NA a 15 flat, set a week ago at the DSM Shootout by a 2GNTer.

I'd say, if you want a daily driver that's dependable, stick to a tune up and some BPUs for the 2GNT there. Yes, they can handle boost and rebuilding and all that, but didn't you want something that was cheap to drive and maintain so you could dump your money into the 4g63? Get your intake, a used header, a GST exhaust (excellent value to that mod), a UDP and maybe put a nice sound system in this one or throw money into the suspension and just have some fun throwing her around an autoX track with the local SCCA crowd. Why don't you look to do something different with this DSM?

 

[SnoopySLR]

I don't know about 15 being the fastest NA. I know the neon is lighter, but my buddies was running 13.7 on slicks and 14.1 on street tires. He was NA, with a stock bottom end. He has a Neon RT, so the gearing is better too.
