well supercharging is good until you hit a certain RPM then they begin to draw more power off the engine

LOL!! Jesus christ guys!! chilax!! LOL! all i wanted is advice on how to improve hp on my stock motor. i'm not planning to go turbo or swap. like i said in the previous thread i don't make a lot of money. the maximum that i could spent on the motor is $1000 or less, that's all. if i can't hit 200hp, then screw it! i'll be happy with 150 or 160 hp.

[lsgheero]

speedy, by doing simple mods and maintaining the engine you can easily reach 130ish I posted a link to a site on the first page that details what is needed to reach certain power levels.

[speedygonzalez]

thanks isgheero. right now my MR2 is at 123hp cause of my exhaust system and K&N intake. so i wonder how much hp will be in total with port and polish and after i'm done rebuilding the motor? (also i'm planning to buy the cpu performance chip which is 14hp xtra from JetChips). maybe close to 160 hp, don't u think?

[toy-driver]

123hp is REALLY good for intake and exhaust.

Enzo, stop crapping up threads by posting a sentence, then another....then another. Use the edit button and add text to your post. Please.

you'd easily lose a few hp from the jetchip. its 100% absolute junk that does nothing at all.

the stock intake sucks. its been proven to give an easy 5hp to change out the bend and put a cone on. an exhaust might give you 1hp. you'll probably lose 5hp from porting a 4age head, its too big as-is.

you could put cams in and lose all your bottom end and pickup 10hp for 500 bucks.

so really, you could spend another 500-800 bucks and end up with a whopping 130hp. you could spend another 500 on a piston set and maybe bump it up to 135hp.

i don't know about that TomsMr2, cause i have friend that has a 88 mr2 na and his pushing 145hp with just mild cams, exhaust, K&N cold air intake, headers and the JetChip performance chip. And i helped him with the K&N intake and exhaust. remember i was running 123hp just with the exhaust and K&N cold air intake before the head gasket blew up. the stock hp for the MR2 is 112hp and i gained 11hp with the exhaust and intake. how do i know i gain 11hp? i took it to the dyno and the graph showed me 11hp gained.

Pics or it didn't happen. This is a key thing before anyone makes a claim about power gains.

[speedygonzalez]

well i don't have camera or i can't afford one right now. but whenever i'm done rebuilding the motor, i'll take it back to the dyno and take pic of it and i'm pretty sure it will be more than 123hp. also, why would i lie? i'll be wasting my time if say something like that, fastrax203. plus i'm not that kind of person telling lies to anybody about what i can or people can do to their mr2's. i do research first and then i show proof. besides, there's nothing impossible what u can do to an engine, remember, SKY IS THE LIMIT!!!

[TomsMR2]

because a stock mr2 puts down about 90hp, i VERY seriously doubt you gained 30hp from an intake and exhaust.

edit: not seriously doubt. its just pure impossible. the dyno operator set the dyno up wrong, you got wrong numbers.

[TomsMR2]

spend the 600 bucks, buy a 20v, enjoy the bone stock 160hp.

[Raptor13x]

^ It'll cost quite a bit more than that when all is said and done, but still, it's a good option.

You can't get 150hp for $1000 either.

+1 for the 20V swap again.

venus has them for 650.. i paid 500 for mine a few years ago. its very reasonable to expect 1K for a complete, running 20v. even if it was 1500, thats not a bad deal for 160hp and a drastically better running engine!

or the gze, those run about 500 bucks more though.

[Raptor13x]

My blacktop will probably end up costing me $1500 when all is said and done. Maybe a little more.

[speedygonzalez]

i just want to correct TomsMr2, I'm pretty sure that the stock hp for mr2 is 112hp. i did my research. i think your confusing with the stock SR5 AE86 corolla that comes 90hp. here's my research so far: 1985-1987 AE86 corolla SR5 is 90hp and weighs 2000lb. GT-S version is from 112 hp to 115hp depending the year. the 1985-1989 mr2 is 112hp stock and weighs about 2200lb. if u don't believe me, do some research yourself online please. and no the dyno did not gave me wrong #'s, you guys don't want to accept the possibilities of what u can do on a 4age.

[conor]

He's talking about actual wheel horsepower. And yes, a stock 4AGE will only put about 90 to the ground if it's running well.

You're expecting us to believe that you gained over 30 wheel horsepower from an intake and exhaust? No. The dyno was not accurate.

It's not that we don't want to accept the possibilities.. we already know. You're the one who's new to the car, new to the engine and new to working on cars. If you don't want to believe people who have years and years of experience with this exact engine, then by all means ignore the advice. But don't come on the boards asking for help and then tell everyone they're wrong when they don't say what you want to hear.

well, if you wanna play around with numbers, take off at least 1HP per year old it is (VERY vague rule of thumb, but usually accurate for the most part)

what i posted was accurate, and not only that but proven by trd, and tte, and all the oldskool california big tuning companies, and all the cam companies..

its 2008 man, not 1984. theres no more speculation about what the 4age can or cant do, its pretty clear cut, and the gains are repeatable and expectable.

we're not trying to look down or step on you, were just showing what realistic numbers are and what you can expect.. and more importantly not expect. you're gonna have to be more open to the advice and experience of people that have been doing it for much longer than you have.. or you're gonna have to figure it out on your own and waste a considerable amount of money.

theres GREAT engine options for the mk1. as it gets older, everything gets cheaper too. modifying the stock 4age is the most difficult, expensive, and gives the least returns of really anything.

Not a whole lot more than $600. I get silvertop swaps come out just a hair over $1000 all the time. $1400 on blacktops.

There's always the 2zzge. It can push past 200hp without too much trouble from what I've seen. It's expensive though. Late 4agze's are 180hp stock. I know of a place that would probably sell you one for $700-$800.
