If you're leaning towards the Greddy kit I'll try to find the 300hp Greddy kit thread and the modified Greddy downpipe thread as well.

While 400 would be nice its just not very practical. Once you get to 325-350 you start having traction issues and the Turbos for those power goals get so large you start to notice the lag. I've always said for a dedicated street car the Greddy kit makes it fun. Or if you want a tad more power you can get a tubular t25 flanged manifold and pick up something like a gt2871r. Still get a bump in power and retain most of the early spool up fun but that would be hard on the budget.

If you find a potential kit or parts to build a kit please pm me with these items as i can help you better from there.

 

wantboost: do you know anything about the jrsc?

 

You won't make anywhere near 300. You'll be lucky to.make 250.. And from 3-4000 to redline you'll be making no more power than you were na. There's a dyno graph showing the difference between a jsrc and a drag turbo kit on a gsr.. From idle to 3k the jsrc wins but from 3k-redline the turbo kit at 8psi ran away and never looked back

 

^^
Oh yeah of course, i know that but i think it works better with my wallet ya know? a bit more affordable. ill be payin like 5k for greddy kit all complete and what not. jrsc more like half? maybe 3k tops?

What i was going to ask, is this guy im talking with is looking to sell his jrsc and a couple other parts for 3400. worth it? And which of these do i really not need. i dont think i need the throttle body of the fuel rail. looks like i need the injectors and the p28 to run the jrsc?
hes got:
-Venom fuel rail
-rc 750cc injectors
-68mm throttle body
-p28 s300 with boost control.
-complete jrsc with 12-14lb pulley

 

I'm not a fan of purchasing used parts, especially a component like a supercharger.

I wouldn't recommend purchasing a JRSC kit regardless, its great for off the line power but as stated its not going to push further then 3k RPM.

You can get a turbo kit for right around $3k. It will come with everything you need minus ECU, injectors, fuel pump and tuning.

SpeedFactory Turbo Kit

 

Speedfactory is a nice kit for the money but its too much mite for what he wants to do.
I agree sometimes Im wary of buying a used turbo but the ones i have purchased I've had nothing but good luck with.

And you're not going to pay 5k for a Greddy kit. I see used b series kits go anywhere from 800-1200ish

 

That's the problem/reality with boost, the price to make 200WHP is the same as making 400WHP. Granted there is some wiggle room in there but the basic components are the same and virtually cost the same. A set of 250cc injectors cost the same as a set of 750cc injectors.

Doing a boost project is all about planning; determining current goals and predicting potential future goals.

I sort of wish I was in the OP shoes, I wouldn't mind another project.

 

So theres alot i really need to go research, im a bit new to this stuff, so what kinda turbo kits would recommend for street fun? Why not the speedfactory? Does anyone even stilll make teg turbo kits? U almost have to get them used right?

Anyway looks like turbo is the way to go, im lookin for some off the line power, which is why iwas looking into the jrsc, but i want high end power too, so i guess a smaller turbo would be the way to go?

 

Wantboost was stating that the SF kit is designed for about 400-450WHP, which is beyond your goal. My point is that boost costs about the same from 200-400WHP. So if you only want 250 now but think there is a slight chance you will want more later then just buy the appropriate pieces to make 400 because it all costs the same.

What do you mean by "teg kits?" Turbo kits were popular a few years back because it gave people an easy way to purchase everything in a package but there is by no means any reason why you need to purchase a "package" turbo kit.

 

package turbo kits kinda went away... a few people still make them but piecing together your own kit has gotten really popular. and yes, forced induction costs money but if you get a few things used (manifold, intercooler, piping, bov, wastegate, injectors, etc) and a get new turbo, fuel pump... the vital things, you can save a little bit of money

 

like what vital parts should i be looking for new? Do you think you can help me piece together a legitament parts list? As far as running a stock a block will allow. I dont want to do too much, if any, engine work. just in case i want to take it all off, i want it to be able to pass smog. Something that can get me up to about 300-325 if at all possible.

right now i got:
-DC 4-2-1 header
-aem coldair intake
-act 8.8lb flywheel
-act dragpro clutch
-exhaust (forgot brand but i want to change to skunk 2 megapower rr cat-back)

so as u can see not much under the hood haha all my monies gone to the outside of the car.

 

Oh ic ic, well okay well i guess i will most likely hold off on the jrsc, and start putting together a parts list and start working towards a 325whp set up. if i can do that without modding the motor block too much.

And yeah i dont know much about FI so i figured a package kit had everything i needed in order to install and be good to go. because up until now ive been trying to go smog legal because i didnt know a way around smog regs, but now that ive found a couple people its like a whole new road is now an option. So i know very little, dont even know where to start researching ya know?

 

Boom. All you need to know.

FAQ: Forced Induction

 

Wrong. In super oversimplified terms, there are three parts to a turbo kit. The Air side, which is all bolt on and what the shops (and Ebay) sell you, the Fuel side, where the tune can make or break your build, and then there's the Engine side and how much power it can handle and whether it need to be rebuilt to handle the power you want to make. All you noobs think about is just the air side of the build and trying to go fast,make X power, and impress your friends and neglect the fuel side as if it were an afterthought. This is why you cannot be spoonfed this information like some people are trying to do for you. Because when they do, you learn NOTHING.

So FIRST thing you need to ask yourself is;
What power do I want to make and WHY?
Don't pull a random number out of your *** or think because that Rustang makes 400hp you have to make 450 to beat him. It don't work that way.

Second question;
What's your budget?
Is it realistic? Noobs seems to think that they can make that 400hp on a measly budget of $1,500. That seems to be your magic number. Sorry to tell you, some turbos cost nearly that. Don't forget to budget in all kind of miscellaneous stuff you didn't think of, like a new clutch to hold all the brand new torque you're going to make. Gauges to monitor what you're build is doing. Etc.

Third question;
Am I building up the engine?
If the answer is No then you're limited by the strength of the internals as to what power you can make. If you don't even know THAT then go to jail, do not pass go, do not collect $200.

Fourth question;
How do I get to my goal?
Read and research. Look at similar builds. Don't try and reinvent the wheel. Know what parts work, and how they work with each other.

Fifth question;
Who's tuning it?
A basemap is not a tune. Get a real EMS and get a real tune. That is, if you want to do it right. Most people half-*** it at this point and run their Ebay chip and wonder why it runs like crap.

I'm sure there are many many more points you can touch on but those are what I think are most important. Anyone, and I mean anyone that tries to "help" you when you are unable to answer those questions, isn't helping you.

 

Hey HT, been a litte while, but ive done some looking around and a little more research, I decided to go witha turbo build. I got a drag kit, bought it off a friend of a friend, its been sitting in his garage for some time now, has less than 500 miles on it, so its in pretty good condition. Everything is there, i will need a new fuel pump and a new hoses but aside from that, everything should be ready for installation. As mentioned before i have a 2000 GS-R and the kit was off his 95 GS-R, i read somewhere that the 94-99 GS-R used different down pipes than the 00-01 models. Havent really seen any other issues was just wondering if anyone knew of problems i might run into, so i know what to expect.

The plan right now, is to bolt on to stock motor and run it that way at about 8.5lbs of boost, nothing to crazy. I'll build up the motor and increase boost down the line if i get the chance to. A little insight on potential problems with the piping or set up is all i ask, thanks!

 

Oh you'll have a major problem
You'll blow that motor adding boost to a stock ecu. They're a lot of things you haven't mentioned. What is all in this kit your going to purchase? Downpipe difference between the year is incorrect unless its a 4dr vs 2dr maybe. How healthy is the motor? Of your compression is off you'll have more problems. You can't just slap a turbo on a Honda like you may do pb&j on bread...

 

No difference in downpipe between the years... the integra didn't change

You'll need engine management

 

They changed. A 96 b18c has a longer dp compared to its early models.

325whp on stock I hope you do it

 

That's in stock form for the header. not for a Drag kit. An aftermarket exhaust system is rather a given for this setup. So it really won't matter

If the Drag turbokit came with a Vortech 12:1 FMU, you're limited to 240whp.. that's it. Anything else will require an aftermaket management system and an OBD1 ECU. It's ok to start off with this, but it puts a lot of fuel pressure against your stock lines, which is dangerous.

In addition, you still need a clutch to hold that power. the OEM will not be able to last long with the additional amount of torque you'd be making.

Hopefully you made sure your car was mechanically sound before trying to bolt all that up. And make sure that all the feed and return lines for the turbocharger are NEW. do not use the old used stuff that it came with , as this kit has more than likely been sitting since 2004...

GOod luck, hopefully you won't be on the side of the road disabled that often

 

Lmao the last words are great.

 

Thanks for the help, i will be getting a fuel mangement sytem, it'll be awhile till the kit actually goes on, but the car isnt driven much, it has 65k on it. Engine is healthy. Right now i have the basic i/h/e , exhaust is a skunk2 mega power rr 3" cat back exhaust, and i have an upgraded cluth and flywheel. ACT Drag pro flywheel and an ACT Street pro clutch, they prob got less than 1k on em, had them installed a few years back but like i said, i dont drive it much since im away for college. But aside from the fuel management and dyno i will need, i shouldnt have any problems with down pipes from this kit right? was a little confused with those first comment from SiRcivic

 

How isnt 3k enough? If he grows a set and researches and installs it himself, 3k is more than enough.

 

OP has a lot to learn but come on guys telling him 325 isnt a forseeable amount of power on a stock gsr ? We're pushing 400 on BONE stock gsr running mid 11's right now. Granted it on ethanol and we lifted the head at that power level after a whole night of beating up the car but its still runs has great compression and just needs headstuds and gasket. These vtec motors when dont right and TUNED correctly will take the abuse with the right fuel and timing

I'm not saying the OP should go out and do this as he clearly needs to do A LOT more research but 325-350 is very doable on these motors reliably all day long

you can budget build the **** out of this car and save money for a good tuner. We've got about 2300 bucks in our mid 11 second 400hp gsr. use garrett turbo, use turbonetics WG, ebay bov, ebay intercooler,spa cast top mount, custom downpipe and dumptube, ebay clutch, sre charge pipes, hondata s300, ID1000's walbro 255. hasport mounts very basic setup
