Serious Question

[greenmeanie99]

Ok have been in the shadows lately looking. I got my beater car finally. The eclipse def. needs rebuilt. There are several possibilities here.

One-Forged internals on a new shortblock. Im not paying to get mine fixed

The other options I need help with. I know you can not drop an 420a-t SRT-4 motor in. However can the short block from either the 2.4 l neon or even the SRT-4 2.4L bolt on to our cylinder head. I have seen some people on 2gnt use a Mopar 2.4L but I don't know if they used the whole motor or just the short block. If the SRT-4 block would fit I would use that being that the stock motor can take a beating. However if not I will just take a 2.4 and build it.

Any help or suggestions are welcome. Money is not that big of a deal right now so as long as its not custom work making motor mounts etc. its cool.

srt-4 = no

if you've read at all, you'd know that the 2.4 project is not for the feint of heart...do yourself a favor, and just get a fully built block with 2.2L stroker kit. you'll definitely be happy, and will probably be the easiest way out with least amount of work for you

Dont waste your time trying to pull off some funky motor swap. The Masta was right:

just get a fully built block with 2.2L stroker kit

For once I agree with you....

Eh I'll just used forged internals on a new block and get a metal HG. My turbo is plenty big for more boost. With forged internals, I was thinking JE pistons/rings and Eagle Rods, how much PSI can I run safely with my fuel setup. I was thinking like 15-17 psi.

Just FYI the srt4 motor is not a 420a, it shares the same engine code as the PT cruiser A853. So ANY hope of swap is now nixed.

Therein lies your biggest problem, then. The 2.4 swap will require fabrication of a couple motormounts, fabrication of a new downpipe for your turbo, and might even require some fabrication on certain accessory brackets, depending on whether you want AC/PS. There are a number of different ways this project can go together. You can use this alternator and that timing belt tensioner and so on and so forth.

I can't tell you specific reasons why the SRT4 block won't work, but I know that I am about a month away from helping to install a PTC 2.4 into a 96 GS here in Phoenix. Is there any external difference between the NA and turbno 2.4s in the PTC? I could not tell you, but I can tell you that it's not a signifigant concern of mine.

I would not waste any more time considering the SRT4 block. If anything, bear in mind that you can use SRT4 pistons/rods in the other 2.4L engines. Given the durability in which you're most interested, when I tell you they are nearly dirt cheap (I want to say $50 per cylinder, pre-hung on the rod, but don't quote me on that), you may very well decide to go with SRT4 internals on another 2.4 for your project, but keep in mind that there will be a decent amount of fabrication to pull this off. There is no direct swap for our cars.

Hope this helps.

You started to contribute, but then went into a thread jack. That's not cool. You should make a new post before you dilute otherwise specific information. Besides, the "how much boost" question is bullshit anyways. It doesn't matter. You're going to rebuild it. You're going to turn up the boost when you have more fuel to allow it, so who cares how much boost you can run in the future? No one. You shouldn't either. I mean, you're vaguely detailing your pistons, but you have your magic boost number down to a 2psi range? Re-prioritize and you will get better results faster.

Well then let me apologize. I due tend to ask questions like that on occasion. The JE pistons I'm planning on getting are the 8:6:1 turbo application pistons sold on Howell auto motive. The Eagle rods forged Im not sure the specifics on them. I have 360cc injectors so thats almost double stock size as well as a walbro 255 and a 1:1 FPR and S-AFC. I plan on getting an S-FMU 12:1 most likely to replace the FPR. So being that I have a rather large turbo and and over kill fuel set up for a 5 psi actuator spring I think I would be ok to run more boost with better internals without going lean. You would know more about this then I would. So I am asking would I need to get larger injectors to run 15+ psi or would my 360cc's be ok?
