$1250 for a 2g is pretty dayam cheap and a good deal! I say go for it...it would be better to buy a whole car and alot of the parts you need to turbo the 7g would be easily accessable. You can pretty much use everything parts wise to turbo the stock 4G64 in the 7g in the Eclipse. The only thing that would need to be done is a custom exhaust because has a little bit longer cat back piping.
After that you could easily part out the Eclipse or even sell whatever left with the car you don't need locally to a DSM ethusiast and easily break even or even better make more profit from what you intially bought it for.
<div class='quotetop'>QUOTE</div><div class='quotemain'>i was also thinking that since everything will be there for the dohc swapp....i could go ahead and put on the head also on the 97es.....
in the end i would have a turbo charged 4g64 DOHC....
or should i just swap in the 4g63-t???</div>
Yes, again having a complete car and if you did plan to do the DOHC swap...everything you need is easily accessible. You could go either route...DOHC 4G64 or a 4G63 swap, either or wiring modifications will be required (I won't go into it because the topic has been brought up many times on how to do it). You just have to make the decision on what do you want: DOHC 4G64 or a 4G63????
A DOHC 4G64 would make good power and would produce more bottom end torque than a 4G63. Also you could run a big turbo and be able to spool it up faster compared to a 63. Though a 4G64 won't rev as high compared to the 63..due to its larger displacement and stroke.
A 4G63 doesnt take much explanation on what could be done to it...its been proven many times.You may not get the bottom end torque like a 64..but you sure make up for it in the higher RPM's. Also 63's can rev alot higher too.
It really depends what you want and whats in your budget.
<div class='quotetop'>QUOTE</div><div class='quotemain'>on more question will be about the stock internals....if i swap the DOHC, will i still be limited to 8psi???im not planning on going over that but i was just wondering....and can i use the 95 gst ecu instead of buyng a SAFC(or other fuel management system) on my car for while untill i can get a good deal on one of them??</div>
If you did a headswap on a 4G64...you gain more air flow up top, but you still retain the same compression on the bottom. I have read and heard that you can run 12psi safely on a stock 4G64 all day with a good tune, and personally I was running 10psi reliably for almost a year on -G-rim. You still wouldn't be able to turn up really high boost compared to a stock 4g63 since they have lower compression pistons. I believe you can use a stock 2g ECU on your 97 7g...they should have the same 4 plug ECU. The only thing you would have to do is move around some wiring pins to accomodate the DOHC setup.
The only thing I would change if you bought the 2g is the turbo. The t25 is smaller than the 14b equipped on the 1g DSMs and not as effecient either compared to a 14b. I would at least find a 14b or if you have the extra $$ a 16g (Small 16/Big 16g/EVO III 16g)....just don't use a T25. If you fit that to a 4g64, it will spool it instantaneously which would get annoying during initial acceleration and not the mention be very unefficient at higher RPM's on a 4G64.
