Ok......I have a 95 SE - 5speed.

I'm planning on getting the following for performance:

1) HAI - K&N cone filter + MAF adapter, intake resonator stays (already installed)
2) Budget Y-pipe - cali spec
3) OBX exhaust - muffler and tip
4) possibly the technosquare - since I'm not planning on a MEVI

How much did you guys spend on these mods and in what order would you get each one? I'm not interested in FI so aside from that, what else is a good bolt on power adder?

I dont understand, stock resonator? Just get a Stillen or JWT, if you're gona stay with the HAI.

Get I/Y/E/ECU in that order, that's what I would do/did.

 

A lot of people will come in here saying get the y-pipe first since that is the mod you'll feel the most. It is the best hp for your money.

 

i would go with the ECU first, followed by Y pipe, followed by HAI, followed by exhaust

ecu first because it will be the most expensive and u'll kick urself for not getting it sooner because it dramatically changes the attitude of the car, if u stack up the cost of everything else you get you would see that you could have gotten the ecu first and worked on the little things after that. y pipe because as a bolt on its the biggest power adder. then the Hai because it will be able to breathe better. lastly exhaust because it will be the least power gain, it is mostly for look and sound. remember with the ecu requires 91+ octane to run properly, i would recommend 94 or whatever the highest u can get is. all in all u have a good idea of ur mods and that is how i would go about getting them.

cost wise

ecu is going to be $400-$700 depending on how u go about it
y pipe depends on brand $180 - $350
hai shouldnt be more than $100
exhaust cat back - $400 - $600
just a rear section depends on style and what kind of work for install $60 - $150

 

I'm in about a littlle over 2grand for everything

 

NmexMAX,

The stock intake resonator is the black square object that acts as an extra reserve to fill the cylinder with more air as it enters the intake. It actually helps fill the engine with more air since it is a cyclic event, not just a continuous flow that midpipes provide, which is better suited for NA setup. There's been a few long discussions about intake resonator vs. midpipe and most people have experienced that keeping the intake resonator restores a bit more low end power which the midpipe has lost and instead only added more intake noise. Now, others have chosen the CAI route which includes the midpipe and that has given them good low end power but have compromised high end benefits. I like to have a little bit of both so I'm staying with HAI w/o the intake resonator.



nismos14,

I was reading up on the Technosquare last night and I got the impression, based on the product info, that they reprogram the ECU and customize the data which will enable one to achieve the total performance setup they are looking for, based on the mods added to the engine (ie. High flow exhaust system, high flow air cleaner, header, etc). If you don't "tell" the ECU what you have changed, the engine will continue to run within the stock parameters. If you don't add the bolt-ons first (ie. High flow exhaust system, high flow air cleaner, header, etc), how can you "tell" the ECU what's changed? So it seems like the ECU probably comes after you've installed a few mods or maybe comes last. What's your take on that?

 

Still has turbulence, and hurts high end to a small amount.

 

True, eventhough, high end is not the VQ's strongest attribute. Either way, the pros and cons is minimal for NA setup. It's probably a matter of one's personal preference and what's perceived as increase by butt dyno since that seems to be the perception that brings a smile to ones face (not that real dynos don't). Some mods show increase in real dynos but one cannot tell while driving.

BTW, I've read somewhere in the org that catback systems don't yield much increase in performance because the B-pipe (after cat/before muffler) doesn't have much restrictions and just a good quality high flow muffler yields much more increase. What's everyone's experience on this? I'm just trying to avoid spending unnecessarily and get very little out of it.

 

I wouldn't do a cat back, just a y-pipe. It's been proven before that gains are very minmal and not even worth the money for cat-back exhaust.

 

Apexi WS=$400
budget y= $200
intake=$20(really pointless mod)
ECU=$400
If you stack the mods on top of eachother they'll give more power than if they were done separately. A cat-back gives maybe 5-6hp but paired with a y-pipe and intake it gets maybe 10hp or so.

 

as far as i know they do not program for mods. i've never read anywhere to lead me to believe that there is more power due to mods that are on the car already that have been programmed into the ecu. i believe that the mods will add their own power and the ecu will accomodate those mods on its own. it is the same program on any g-force ecu regardless of modifications. IIRC this is how it always has been. i MAY be wrong so if u find info to state otherwise please show me this info thanx!

 

Here's the link: http://www.technosquareinc.com/technosquareecu.htm . The overall product info is there. However, when reviewing the features for the 95-96 Maxima, it says fuel map and ignition timing map. Isn't this what JET'ting does but for a lot less?

BTW, does anyone have a dyno sheet for the technosquare ECU?
