adding an aem intake, wolf chip and catback system to a 5spd '90 240sx. Curious to know the hp gain I would get.

 

intake..maybe 10hp catback.....maybe about 15hp and sombody correct me if im wrong but the wolf chip about....20hp

 

what's a wolf chip? is it one of those resistor that cheat the temperature sensor?

 

I think it is Jim Wold technology after market ECU, Im pretty sure they reprograhm the ecu twords performance.

90,240sx those are very gracious number you gave those upgrades...those #s are usually very rare

 

I really doubt that the intake would make that much. I'm not exactly sure what the wolf chip thingy is, but with just intake and exhaust, I'm sure them 2 together would only make about 15hp, if that much.

 

intake and exhaust add about 10rwhp...dyno tested...not sure about what the JWT would do...but maybe another 10rwhp...but then again never had a car to test.

 

to the wheels? You'd be lucky to get 20whp out of those three. JWT makes an ecu programmable for if you have an intake, exhaust, headers, bigger cams, a turbo, etc. So it helps take advantage of the mods you have. It's not a cheap resister that fools your car like you seen on Ebay that ruins your car.

Thats about 1K for 20 hp, whether it's worth it to you or not is up to you. Personally I'm not getting a chip until someone makes them cheaper, or I go KAT.

So what is the cheapest way to get the most HP from a mod/mods? Or is it something that you have to invest a lot of time and money, totally rebuilding an engine and/or adding a turbo??

$1,000 seems like a lot of money just for an extra 20HP- Would a gain of 20HP even be noticable? Would modding the air intake and the exhaust really do much of anything noticable besides better gas mileage? Would one actually be able to feel more power?

BTW, would taking out the AC pump and the power steering pump free up much horsepower? That would be free of course, just the time involved and possible 5 to 10 HP gain (maybe??)....

 

every pound you take off the crank frees up i think it was 2.7 hp. i would get some pulleys and a header before i got the ecu. and yes if you take the belts off you will get a little bit of power. i wouldnt buy a cat back either. i would just get a cheap exhasut off ebay and have a muffler shop put a straight 2.25 pipe back to the exhaust. you will save some money that way and have the same gains. most all the muffler are built the same way, a straight through design. also with out a header an exhast might give you 3-4 hp at the wheels. and intake should give you about 5 and the chip i believe was 12 to the wheels.

 

bye a de head and the rest to make it work, jump to 11.7 c.r. and be happy , lol and maybe sum bigger injectors to feed it sum fuel that should be around a 1k.

 

ebay exhausts are a bad idea from what i'm told. Get a muffler you can trust that you know will sound good like magnaflow, and get a cat-back exhaust made 2.25"-2.5" from a muffler shop, it'll be ~250, but worth it, compared to the Apexi N1 Which retails for $550 and is not much if any better.
Don't remove your power steering and such unless you're a die hard hp fan and every pound counts. And if thats true, go on a diet, lol.
ECU isn't normally done unless you have everything else done. Your best bet would be intake for ~150, Exhaust for ~250, and a Header ~350-400. That would in reality get you 20-30 hp. Having all three adds up as well, with a header it helps the exhaust as well.

And upgrading to a DOHC isn't that much of a diff, but if you have a high milage engine it's a possibility.

Just keep reading and researching and you'll decide what to do. Don't forget suspension and braking and other aspects of the car as well.

Once again the advice it fantastic! Thank You much keep it comming!

 

lol, no problem.

with what sounds like your experience, thats about what you should do, anything more gets a little mechanical, like cams or pulleys, etc.

there are tons of minor things you can do, like removing the clutch fan and adding 2 12" radiator fans from a altima or something to help cool, or a lower temp rediator for the summer so your car will run cooler, 300zx fuel filter, NGK plugs & Wires, remove you AIV, try seafoam, etc

I don't want to get really tech. My 1990 240 is perfect mechanically with only 82k. I'm debating adding some pep for no more than 1-2k. or buying a 2nd gen. and doing an engine swap or buying a 2002.5 VW GTI or 2004 RX-8. If I spruce my current ride up I'll save $ and go all out in 4 years. I don't know if I want to get involved in swapping engines, clutch, and what not to a 2nd gen. I want reliability, besides I want to do it and enjoy. No nickel and dime high school **** (I'm going back to school). That's why I'm leaning to buying a new car. I fig. I'll talk to my mechanic and a couple of shops to see cost, reliability.
