    I know there’s info all over the web about these cars especially on this site but I would like advice/feedback from others directed towards me. I recently bought a 97 and a half (98) eclipse gsx with 73k original miles with barley any rust. My current goal is to fix what little rust there is and maybe do some upgrades. Not saying that the car is a unicorn but considering it’s a Michigan car that’s basically all stock rust free and has less than 75k miles it kind of is a unicorn. At least to me. Should I leave the car the way it is? Since it is a fun car at the end of the day. Or should I do some upgrades to get close to that 400bhp range? (Nothing too crazy) No link atm but I am looking around for one. It does have a wideband (needs the sensor installed) oil pressure and boost gage. I am currently at 16Ibs on the stock 14b with a boost regulator. Rear posi as well but that’s all I really know about the car. If anyone thinks it’s worth putting some decent parts in without affecting the reliability of the car please tell me your suggestions and or feedback. I’d like to run e85 and at the very least with a 20g. If I do end up dropping some money into it. Money is not an issue but I’m not interested in anything over 500 to the crank. Ps the afr is actually reading 14:8 not 4:8. The 1 doesn’t show on camera.

    I guess you took a step in the right direction coming here. Enjoy the car and learning man. Ups and downs await. :)

    My advice, being a few years with the DSM’s:
    *The racing community here has —>S E R I O U S <— depth.
    I would tastefully mod, but not go overboard. Most the DSM’s do not come with the RWD tax. Your rate of return is MUCH lower. Outside of really getting into racing, and outside of being a diehard DSM’er, I would tread lighter on dumping money into the car.
    Alas, the world’s your oyster though man.

    Before anything I would do all the regular maintenance. Timing belt if you don't know exactly when it was last done, fluid change for the engine and driveline, worn bushings and mounts tc etc. Then mod 1, in my mind, is ecmlink. Everything after that will be made so much easier.

    Good luck man. This forum is full of information for you and be sure to post specific questions you can't find the answers to as there are more than a few DSM experts to help you out.

    Maintenance is #1. New plugs, wires , all new fluids , timing belt/ water pump, fresh oil and filter. I wouldn't push more than 300 whp on these motors without some sort of bottom end build.

    Just FYI, I do have a DSM link that I will be selling soon. As far as I know it's the latest version, fully updated, everything.....I only drove the car a few times before taking it to a friends shop to be rebuilt how I want it so I'll just have to double check and make sure it's the latest version. I decided to go with a stand alone system so I won't be needing it anymore. I've also got some other parts that I decided to replace/upgrade like a GX35 turbo in good condition, only I'm not sure if I'm gonna sell that quite yet cause I'm considering putting it on my 2016 Tundra TRD Pro along with the intercooler, but I've got a tubular exhaust manifold, 3" downpipe and catback......one of the two is a Greddy, I can't remember which one. I've got a few other things too.....just can't think of them off the top of my head right now.....I've got way too much crap going on and I can hardly think straight haha! My friend who's building the car for the most part knows a lot more than I do, or I should say than I can remember, but if you're interested in anything just let me know! It's all already sellable, I just haven't had the time to go through the parts and take stock of everything I have for sale and post them. It will happen eventually! But like I said, if you're interested in anything, let me know and I'll see what it's going for and give you a slightly better than fair price!

    I like everything Vegas Smith said, the pump and injectors are bigger than i run, but you did say e85 so that sounds perfect, I would recommend ARP head studs, they are cheap, very easy to install if you do them one at a time, and give you a piece of mind, I feel my head gasket would have already gone without them.
    I just hit close to 400 (378) a couple months ago, and I'm very happy with it, it took about 2 years of fixing it then modding/tuning with link, and around 12k including the cost of the car, (but probably 40% of that was not towards power)
    But the busted knuckles were definitely worth it, these cars are awesome!!!

    Well I’m definitely interested in a link but I’d also consider some other things. Just pm me or send me a web link to the items. Thank you

    Ok cool, just give me a few days to get a list of everything together and also think of fair prices and then I'll send you a PM or a link if I get the parts posted. I've got a ridiculous amount of things going on but I'll try to get this stuff done fairly soon!
