Play nice guys..


And it should be very easy to eliminate the CEL.. Just put a resistor inline with the rear o2 sensor.

It is probably the same as a DSM, BUT I HAVE NOT TESTED THIS YET. SO MAKE SURE BEFORE DOING THIS MOD!!!!!!

goin off topic is cool, thats normal in most forums, but posts stemming from what seems to be jealousy and hateration, not cool. and yes 25g is what i said and is what i mean. here in south florida if you arent putting down more than 400hp to the wheels then you arent shiet. the guys that do work for me are all +480 @ wheels. if you arent at those levels, you dont even partake in the conversation when the big boys are speaking. you go and chat with the honda boys. thats just how it goes, so dont front about something you dont know.

i find this somewhat sarcastic and irrelevant....

but the external waste gate will dump into the atmosphere relieving some of the pressure in the down pipe and exhaust. it is also a larger valve and can keep higher boost in check. im no expert but i thats what i know.

plus i keep seeing posts about boost spike/creep - all on stock turbos with integral wastegates. guys ever think of the problem being the integral wastegate in addition to the boost controller? the hks controllers are known for boost spike. (y would anyone even get an hks controller???) ive seen hp gains in cars that went from a downpipe dump to an atmosphere dump wastegate. the dsm shop i go to taps into the stock manifolds and welds an external wastegate on them. very inexpensive means to getting an external wastegate without a whole new manifold, especially since the stock one is very good. external wastegate looks cooler too

thanks for the recent comments about the rear o2 sensor. im gettin the feeling that a hi-flow cat and a ECU reprogram should do the trick when these items become available.

 

To try to answer this question, Pruven performance told me that a straight pipe will decrease boost by 1psi. Pruven said to correct it, just use your boost controller and set it back up. As for the CEL light, mine is constantly on (97 Eclipse Spyder GST), with my straight pipe because the 2nd O2 sensor detects it.

 

I could not agree more.... I cannot see any way to improve the EVO with stuff like H&R springs and such. Man, you gotta drive the freaking car!! It's unveliavable tight handling and quite a firm ride too... Also, talking about a bigger turbo already is a little premature. The EVO as it si can make 20-40 more hp with minor mods (from Ralliart). It would be IHMO, a big mistake to just start doing mods to this car. It's not a freaking Civic or OZ or even a WRX By the way, when I got my WRX, I went to a tuners' shop where I saw a silver WRX. The dude had just bought the thing and already had an intake, exhaust, lowering springs, coil-overs, blow-off valve, bigger turbo, big *** wheels, body kit, big stereo, DVD player... man, you would not believe the stuff this dude had bought.. I got pictures of the thing. Hey, the funny thing was that the guy could not even drive a stick!! He was crashing gears and stalling the car everytime he drove it
Hey, to each his own and all but that was pretty ridiculous as far as I'm concerned. The man did not even find out anything about his car before he started paying lots of $$ to bolt crap on. I'm sure his car is a freaking mess. I bet it runs like crap, rides worse than a slammed civic and handles like a '56 Chevy......
I say go very slowly and carefully before trying to improve something that's already almost perfect

 

whats with all the lectures?
so u think that i think im driving a civc or a OZ lancer? thanks man, i appreciate that.
u think that its a big mistake to just start doing mods to this car? if getting custom metal work and fabrication done to ur car is new to you then maybe you should keep ur car stock. its not new to me....

yall act like when you get an evo thats it - theres nothing better you can do to it. or u assume that any immediate mods are done on a whim and not thought out. whats up with that? its a great car, but its also a great car to build upon, just cuz u dont agree with my list of future mods doesnt make them wrong. my last car was putting 380@wheels off N20 from a 1.7liter w/ a t3/60-1engine on pump gas. i know about turbo lag, so lets get off the "25g is too big" subject. 25g is an awesome turbo and would give the evo supercar demolishing power (thats all the car needs since it already has supercar smashing breaks and suspension) . in terms of handling, yes h+r springs arent tein coilovers, but tein coilovers or any racing coilover for use on a street car for a college student is kinda overkill. i figure that the h+r wiill keep most of the factory ride with just a lower stance - exactly what im lookin for. i dont know about yall but i got the car to upgrade - where im from if your not puttin more than 400+ at the wheels then you dont join the conversation. im going to be in the conversation.

 

Man, do what you want you know?? Obviously you are far more learned in these matters than some of us...... good luck and forgive for intruding in your conversation

 

I read the engine tuning thread posted by claudius not to long ago and I find it to be very informative. IMO I believe that you should start w/the basic power adders. By doing so you are cost effectively tapping in to the full potential provided by the motor. And may very well be impressed by the power unleashed. Then when you decide to go on to bigger mods ie. bigger turbo....your car will be more equipped. and you might be saving your self from headaches . as far as suspensions, i traded a 98 cobra for the evo8 and the evo out performs the mustang IMO. the suspension is well balanced as is. I believe replacing the stock springs can ruin the suspension dynamics. If your intent is to lower the car simply for looks, lowering springs IMO will comprimise the suspension performance. Your'e better off by purchasing the adjustable like TEIN so that you can slam it for the car shows and then adjust it to suit your driving preferences

-my 2 cents randy

 

i do plan to start with the basic power adders in order to get the most out of the stock turbo... thats y im askin about the full 3 inch turbo back exhaust. heres a quote from my original post - notice the part about getting the most out of the stock turbo FIRST, then later more aggressive upgrades.

y are yall so offended by my list of upgrades? lol


oh and wheres my post where i said "focking hater"? yall took it off huh, thats messed up.

 

I could not agree with you more. See, the moderator(s) that dont like you, delete it.......believe me, I know!

About your mods, I agree with everything. You'll be hard pressed to find a 25G reverse rotational wheel here in the states, BUT maybe some of the SF(south florida) guys can get there hands on some. I know there out there. If they do, shoot me one . I too am planning on modding the car using the most of the STOCK turbo (do you think they saw that?).

Good luck,

 

ya know, i sense alot of mis communication here.

What i see:

-ADM i snot just throwing all this stuff on the day after he gets his car like said WRX gear crashing guy. Who knows, this could be years down the line. We all know that when you get a new car it feels great, but its not too long before you crave more power no matter how much your car came with.

-Cladius knows his poop. He was just asking for clarification on ADM's statement which was promptly given, no need to bite

-CoolGuy's frustration is directed at the mitsu-markup, not ADM. It is just so immense that it manifests elsewhere on occasion take no offense (BTW: coolguy, if you are still looking for an Evo at MSRP and are looking across country shoot me a PM or AIM.)

-Tein suspension too overkill for a college student? how did you get an EVO then lol (i mean no offense, just bustin ya ***** )

-Moderaters delete messages that solely contain curses/insults and lock threads that get out of hand for the sanity of us all. We should be thankfull for their vigilance so this board doesn't degenerate into something...... monstrous.....

-ADM: The resistor is a good fix, but i wouldnt say is a cover all if your modifications are going to be HUUUUUUGE. The O2 sensor is pretty much a voltmeter, and with the extra air flow, it reads over what the ECU thinks it should, therefor throws a CEL and compensates in the A/F mixture. Resistors offer static resistance and, although you can continue to change the resistor, a more pragmatic solution would be either stand alone management or the ECU re-program you had already suggested. As for having it just for the turbo-back during the interim before your turbo upgrade and such, the resistor is a great fix

-Last and least, i do only drive an OZ (with a Tein coilover suspension and yes i am in college) so you can all tell me to shut up and get out of this evo thread if im overstepping my boundaries.

good fight and good night

EDITS: Spelling, and im sure i didnt get it all

 

i wanna see someone do a divorced wastgate!

 

oneeyejack - good post man. the resister is gonna be a temporary fix (like 1 or 2 years temporary), until i get the 25g for me and gvr4v and ill decide to either go emanage or complete standalone - just the fact that standalone is kinda pricey and there are no wire harness/jumpers to keep from cutting the factory harness. maybe if a harness comes out for a standalone ecu i will go with a DTA system - thats what all the big guns are running in south florida. DTA + 25g = pavement cracking power!

 

u just dont quit huh claudius.

"if you dont blow the engine" - you cant wait till i blow my engine huh, so u can be like "i knew it" or "i told you so". wtf. lol. it aint gonna happen man.

just cuz u do it doesnt mean its right. 31 psi on an internal wastegate sounds like you really werent gettin the full potential out of the turbo. sounds like a half *** job to me- just get the new exh. manifold w/ external wastegate - you should love the improvement. but wutever man, do what you do. i guess internal wastegate is the way to go since u use it and race engines dont use them.

whats so laughable about 400hp with H&R springs? i guess that was one of those "you had to be there" jokes huh. as long as it makes you laugh, it makes me laugh cladius.
