So I'm pretty new to the 4g63; I just got a 96 GSX recently, and I'm looking to do mods; I have done all of the maintenance on the car. I've been reading up on some of the basic mods, but I still have some questions unanswered... I'm looking to go the evo 3 big 16g route, where would I get the main parts? Fuel pump, injectors, fmic, turbo, etc. And which fmic would allow fog lights to stay in?
 
Some good reading here:
http://www.dsmtuners.com/threads/2g-dsm-upgrade-paths.486217/

Some personal advice before throwing bolt-ons at your car. Get a wide band o2 sensor, boost gauge, and way of logging/tuning so you are making more power safely.

I have had very good luck with supporting vendors on this site. If you want a one-stop-shop, extremepsi is a supporting vendor on this site.
 
Yes I have all that basically. I'm looking into a black box ecu right now. I have a wideband, 3" cat back exhaust, boost gauge, mbc, greddy bov, megan o2 housing and down pipe. I've been going through like extremepsi, buschur, and rre, but man that stuff is expensive... I mean an evo 3 big 16g was $1k
 
here are other options as well. You could roam the classifieds for turbos that pop up rebuilt from reputable freelancers on this site. You could look into some of the hybrid turbos using machined 14b and 16g compressor housings for larger wheels hat have been popping up lately in the classifieds that are zero-mile rebuilds in the $400 range. Unfortunately your going to have pay-to-play. Keep your eyes out for deals that seem too good to be true (because they are). Pay for quality parts and you will get quality results. There are many parts I don't mind purchasing used (exhaust and intake mostly) that can save a considerable amount of money. When you go to upgrade, some of them can be resold for what you paid for it.

Well with turbos you can find a decent used one for a couple hundred and get it rebuilt by JusMX141 on here hes the resident turbo builder. Fuel pump shouldnt be too expensive and a walbro 255 should do nicely and an aeromotive FPR. Also, sell some of your old stuff to help pay for new stuff.
 
Punishment Racings FMic is said to clear the fog lights. It's pretty inexpensive as well. No modifications needed (if you remove crash bumper).

It's a proven choice.

This would be my choice.

The rest of the parts,you are just going to have to pay man, sorry.

There are DSMlink setups that pop up in the classifieds.

As for fuel delivery- I prefer to go new. I wouldn't risk buying fuel components used but that's just me. You know the dude, xXhondakilla42069Xx, yep, that dude. He said his really cheap performance injectors were only ran on high octane for 100 miles so they should be good to go.... ;)

Seems you already know where to get most of the parts since you've already began upgrading. Just keep at it. Spend that cash when you can.
 
I understand about paying to play, but I guess my major concern is the supporting mods. I have the 255 in cart, I'm just a little lost when it comes to the fuel regulators. Pertaining to the an fitting and different types. Would the AEM universal one work? Also, would it be fine to find used ~650cc injectors? And as far as the FMIC goes, would I be able to keep the crash bumper for a FMIC? I'm just worried about something happening and ruining everything.
 
In addition to the 255 pump, get a rewire kit to provide constant/consistent voltage if you have not done so already.
Here is a popular fpr that even has an install kit:

Rewire kit:
http://www.streettunedmotorsports.com/parts/stm_fuel_pump_rewire_kit.htm

Injectors can be good used if you check out the ratings of the seller. Also consider having them cleaned and flow tested. Some even pop up for sale that have already been serviced.

Most fmic kits will require some modification of the crash bar. That is just something that will need done to fit one onto a car that wasn't originally deigned with an fmic. The crash bar cut very easily with the right tools.
 
Does the punishment racing require cutting or full removal? I can deal with cutting; how necessary is the rewire kit? My goal is 400bhp max, maybe 500 down the road. Would the rewire kit be needed for 400?
 
I would get what your gonna use to tune as your first upgrade. Get familiar with tuning. That will eventually help you get to your 500 hp goal. There is a lot more to learn in that area. Rewire the fuel pump that's something you only have to do one time and will let you use full potential of any fuel pump you use
 
All a pump rewire does is give higher, more constant/consistent voltages. This allows the fuel pump to maintain higher pressure/volume at all times, whereas it might fall off on the stock wiring at higher boost levels. The link I posted was an example of a kit. They can be purchased elsewhere for a lower cost if you shop around.

No, it is not required. It is a good idea however unless you don't plan on pushing the car. Here is some data on amp draw from various pumps to help paint a picture on how much different fuel pumps can draw:
http://www.roadraceengineering.com/fuelpumpflowrates.htm

The black box reflash is perfectly capable of getting the job done. I have used Maf-t, SAFC, DSMLink, and the black box for tuning. I have preferred DSMLink as it is VERY user-friendly and does not require multiple programs to flash/log the ecu. Linking to the ecu is very consistent as well. here is a forum solely to support DSMLink. I did not like tuning as it was a pain in the but to get it set up properly (installing drivers and program versions were a hassle). Both have great options and features.

Alright, thanks for all the info guys. So, I'm looking at a 255 pump with install kit, rewire kit, aeromotive full pressure regulator kit, possibly PR FMIC kit, and I believe the last will be the evo 3 big 16g, and 16g install kit from extremepsi and 650cc injectors. Would you be able to help price the 650cc injectors and a used evo 3 big 16g? Verifying that I'm on the right track of course.
 
Here is a YouTube for the PR front mount from a fellow DSM'r.

It shows in really good detail all the things you will need to cut.

You must be logged in to view this image or video.

Also if you are going 650 injectors you WILL need to start thinking about your tuning solution. Ceddymods will work fine as 2gmitsu said if you don't want to fork out for eprom and the link kit.

There are 16g's all over the classifieds here on the forum. At least 3 I've seen in the first 2 pages of the "recent classifieds" tab at the top of the site. Don't fall for the cheap ebay dark side though.

As for used injectors- there is a guy selling a set of RC 750s for $135obo. He posted the injectors like an hour ago. If you are going 16g and want 650s you might as well just go 750s and you will have headroom for future tunes/boost levels.

Just always visit the site and you will find everything you need.
 
Hmm, alright. Would do you think of the prices for the evo 3 big 16g and the 750s? I'm trying to look around, and it seems like a good price, but then again, I don't know too much
 
Does the punishment racing require cutting or full removal? I can deal with cutting; how necessary is the rewire kit? My goal is 400bhp max, maybe 500 down the road. Would the rewire kit be needed for 400?
If you've seen how wimpy the stock wiring is, you'll want to upgrade it and yes its necessary if you want to get the best from your pump. Its not hard and that particular kit is fairly costly because its really dam clean. You could make your own easily if you're into that kind of thing. (That's what DSMing is all about)
 
I see the prices on extreme and another site, they don't seem that bad for costs. The last part I'm considering now is the turbos and injectors... I feel I should start lower with the evo 3 big 16g, because the spool would be lower. But would that hold at 400whp or close to? I'm seeing like 375 max. Would I be better off going with the td06-20g or fp green? Would I be able to use 750cc's on either 3 of those with the the right tune? Would they be maxing out on the fp green?
 
Once you set your HP goals, you can then know what supporting mods are needed to reach that goal. 400+ hp, 20g turbo is good. If you plan on going higher, I suggest building from the bottom end and move on up. Good clutch kit to hold your power goal is definitely recommended
