hello members of ht, i am new here and id like to ask some questions, ill just jump to it
i have a 99 gsr w/ 83k miles on it
i want to go N/A
so far the only performance mod i have is cai, im geting my exhaust done in about 2 weeks
i also would like to get a fues pres. regu. and some injectors (what is a good size for all motor?)
after these ill have a budget of about ~500-700$
i just want to get as much power possible with that amout of money, no real # goal

some pics





ty in advance

 

i don't think theres gonna be much of a diff with rail,regulator and injectors.

how about some cams? or maybe a little bit of tuning for example. vafc, hondata

 

Get a properly sized header, and hi flow cat for your exhaust, so you get rid of all your bottlenecks. Cams could also be done but probably arent going to fit in your buget after a good header, and tunning is always a good idea.

good header, hi flow cat and a VAFC perfect for your budget

 

my old GS-R setup in my sig treated me nicely!

did cost me a lil over $1000 tho...

 

You don't need injectors in a stock engine. Once you up the compression and run some aggressive cams, you might be able to think about it.

 

that junk you listed is going to do you no good...

you wont need to touch the fuel system until you start modding the internals...

you can get a decent header/custom exhaust for $700...

power=money

 

and stay away from piggybacks like SAFC/VAFC's. When you use them to richen your fuel, they also advance your timing (they are just modifying the MAP signal, giving it a false reading to do what you want it to) and that can lead to problems. With your budget, id invest in some suspension. It was the first thing i did and have NEVER regretted it.

 

fuel managment wont really help until you get a little bit of muscle in there, best option is to start building that head id say

 

get a rocket cam,valvetrain and ecu package.

 

I'm surprised nobody suggested nitrous. My friend ran a 55 shot on a stock 98 GS-R and ran faster than a stock 99 Mustang GT.

I think if you do a 75 shot with some tuning (probably past your budget unless you get a used Hondata), you will be decently fast for N/A and still have great reliability depending on how often you spray and the tuning.

 

well the exhaust is pretty much paid for which leaves me with 750$
should i keep the stock gsr IM? or get a blox or skunk2 style? what is a good company for cams/gears?

 

First thing you should is have your suspension setup, then think about the power..

keep the manifold for now, its good for midrange power.

get some king of header, there's quite a few JDM ITR copies out now for cheap. high flow cat/test pipe and maybe some used CTR/ITR cams.

 

get some dsm 450's, and a new ecu to run them ... like racingchips.com get some headers and a new muffler, you'll be within budget

A fuel rail and injectors aren't going to do diddly for you. Fuel rails are only necessary on cars producing more than 400hp. Injectors are for cars that warrant more fuel, right now, bolt ons aren't going to warrant injectors. A fuel pressure regulator would be ok, but it's tuning capabilities are limited. Plus, you'd still have to spend money on doing to a dyno and getting a wideband hooked up just to tune it.

Do you want to drag race, track race, auto cross? We need to know what you want out of the car.

I would suggest getting a short ram over your CAI, and getting a Skunk2 intake manifold, or other type. Then get a a good header with a 2.5" collector. For an exhaust, i would say get an RS*R exmag, but from the way you worded it it sounds like you're having one made by an exhaust shop. Hopefully it's mandrel bent, otherwise don't waste your money.
I had a 2.5" crush bent exhaust for two years, then got the RS*R exmag and instantly noticed the difference in power delivery.

If you don't buy the fuel stuff you talked about, you could combine that money with the 500-700 you mentioned and have close to 1k. With that you could get a decent header and exhaust. Next step would be a high flow cat, intake manifold, then some form of engine management and a tuning session. After that you could decide whether or not you want to keep pursing NA, i.e. pistons cams and what have you.

Nobody mentioned nitrous because then it won't be N/A. Nitrous = forced induction.


I have nothing else to add, everything you need to do has been stated by others already.

ell i already have springs/shocks (if you havnt noticed my car is lowered)sorry i failed to mention this but it seemed obvious i had something.

im thinking of a dc 4-1,aand yes im geting an exhaust made, but i was thinking 2.25in, would 2.5 really be that much better?, also im going to run a straight pipe not a cat, (i know thats insane coming from a person in CA, but dont worry ) but one thing i dont tthink ive gotten across is my budget is excluding my exhaust system i want 750$ to spend on other mods such as IM,cams, gears, valvetrain w/e etc etc. i guess i wont get anything fuel yet. car is DD, i dont really have a preference for track, drag, autox etc. i just want an all around car, if i had to choose though id say track car.
thanks

 

Well, with that budget i would get some used 01 itr cams or ctr cams (Same specs). Then i would get a nice header. Preferably a used smsp, dtr, rmf.etc. Your going to have to settle with a used header because these high end hand fabricated ones cost about 1g new depending on which one. If you wanted to go brand new, i would stay away form dc sports header. Go get a jdmshit 4-1 for 179 i think and then have your exhuast place cut off the crappy 2 in. collector and weld on a 2.5 inch one. Youll be very pleased with the increase in hp.

When you save up another 500, you should then get hondata or other tuning device and pay to have it dyno tuned. It will be the best money spent. Trust us. We've seen lots of power made by tuning your performance parts.

EDIT: You have no need to really spend money on a im right now. The factory im will do fine with what you want. If you plan on running a 180 whp + car, then i would invest in a jdmshit/skunk/blox im. The gain on a light build as you are doing wont justify the $ spent.

alright ill take your advice. i guess il get it dynoed after everything is done and such i didnt want to get vafc or any sh*t cus i dont want to mess anything up
thanks very much

 

I think most people are saying 2.5 instead of 2.25 because that's what you'll eventually need, so why have to change it later on? Right now, it won't make a difference.

 

You get what you pay for.
Don't get a dc sports exhaust and expect to make lots of power.
Since you were thinking about injectors, I am guessing you don't have to worry about smog laws.
N/A set-up's are easy, start with the breathing of the engine:
Intake
Header
Exhaust
Hi-flow Catalytic converter/Test pipe
Then internals(how far do you wanna go)
Top end:
Cams(which stage means how illegal and how much engine work you wanna do.
Cam gears
Intake Manifold
Fuel Accessories (injectors/FPR/Fuel Rail)
stiffer Valve springs, possibly new valves/retainers
Maybe a port/polish job on the head.
New pistons/rings in the block
Why not boar it out and sleeve the block with 84mm sleeves to make the engine a true 2Liter instead of a 1.8L.

How far do you want to take it. How much money do you want to put into the engine. Also, once you install cams, you need either a vtec controller and some sorta fuel controller.
So either Vafc/chipped ecu/hondata/crome/uberdata, and needs to be dyno tuned imediately(sp?) so it doesn't run to lean.

 

yeah your going to be spending a lot of money if you want power. ihe is a good start.

btw- your car looks like mine. cept i have blk int no spoiler and itr lip

thanks for all the input so far, i wasnt planning on geting a dc exhaust just 4-1headers; ive heard mixed good/bad about this. any excess input??

also fergy, what rims do you have? our cars look identical from what i can tell from your avatar picture

 

I have stock blades on it now.

The dc header doesn't have very good airflow characteristics.

check out http://www.sms-products.com/ or the jdm honda header

When I had just bolt ons, I had a buddy with different bolt ons.
He had less miles on his engine and I still pulled 8 more hp on the dyno. We did 3 base runs, identical year car and everything.

So making the right choice on your bolt on's makes a huge difference.
