What JRSC setup are you running?

[Veris]

It is an unported blower.

[MrDomino]

I saw somewhere in this gigantic thread that the following motors put out around a maximum of the following:
B16 - 260whp
B18 - 280whp
B20 - 300whp

I was wondering if these were correct and why the B20 (a motor which puts out less hp to begin with) is capable of 20hp more than the B18

[JRSC•GSR•EG]

i would guess the larger displacement of the of the b20 has a lot to do with it, if i ever mess up my gsr bottom i will be going with a b20

So do you think it's worth it to start with the B20?

I stand corrected.

[crxsir1591]

yeah guys im running a b16 head with a b18 bottom end with greddy ultamite piggy back
dc sports headers 440 cc injectors short ram intake uprated fuel pump
what plugs should i run ?
and what fuel pressure should i run ?

i have been looking in to this, alot of people tell me the sleeves suck but i seen people put nos on b20/vtec motors with no problem

i would say its worth starting with... where i'm from if you blow it you can pick up another b20 for like a couple hundred bucks

i have to find out what b20 vtec set ups are dynoing at, i here you can make over 200whp on just the b20vtec set up, even as much as 220whp, so then you throw a charger on there maybe keep it at 8lbs get a tune and hope to be at a nice 275whp... maybe get it tuned with an 10 or 11lb pulley at the same time, so when you want you can slap on the other pulley throw in your 11lb eprom chip or (how ever you store your tunes) and smoke all those cammed out v8's and then when your cursing to work throw in the 8lb chip and slap on the 8lb pulley


well thats my plan or idea i have been messing with, i think cause i already have a gsr supercharged in an eg hatch, all i have to do is charge the block, hook up the vtec and get it retuned. all can be done for a 1000 or so...

i'm not a honda guru i don't work for them or anything if anyone sees why i shouldn't try this please let me know...

[morepoop4u]

I'm tired of blowing my collector gaskets on my kami headers so I'm going to weld it into a 1 piece and mod it from 2.5 to 3" then thermo wrap it. Last time i dynoed at 9.5 psi was 243whp and 170 ft lbs on my 99gsr. Hopefully my butt dyno with notice a difference lol.

[Seedc2]

Does anyone know how to wire up an AEM UEGO on a 98gsr running hondata s300?

[ekkilla23]

has anyone on here port matched their manifold to the head? im being told by a couple of my retard friends tha im not goin to gain any power from doin this beacuse a charger is forced air...now i understand wat they are saying but i dont at the same time so can someone please help me out with this...also wat should i have my fuel presure set at? my set up is a gsr with type r cams 450 injectors walboro 250 fuel pump golden eagle fuel rail and regulator...2 1/2 inch strait pipe with obx strait flow muffler and 4-1 megan headers...ok so heres my biggest problem im having rite now well idk if its a problem but im confused soo i did my set up and i got no cel my vac is good and the blower is holding boost at a steady 8lbs so everything is good but i cant hear it!!!!!! well let me correct myself i could a lil bit at high rpms while im shifting but every video i seen b4 i did this set up, seems to me like u could hear them from a mile away???? is there sumthing wrong???? some1 please help me out

First, use complete sentences, actual words, punctuation, and paragraphs. Nobody wants to read through a bunch of garbage like "bcuz" and "some1".

I don't think port matching would result in a huge power gain. For NA engines air flow is pretty much the main concern. Port matching would definitely help an NA engine to produce greater peak WHP but the difference probably wouldn't be as noticeable (if at all) for a forced induction engine since you're already flowing so much more air.

Bottom line: your friends are probably right.

First of all, wow, welcome to Hater-Tech!

Second, while everything is under pressure it is still moving. If you have the opportunity to port match the manifold and/or the header without getting shavings into your engine, do it. Power is made through airflow. Anything you can do to make air flow easier through an engine will contribute power.

Third, MrDomino, just yesterday someone had to explain to you how a bigger engine makes more power than a smaller engine and today you are giving out advice?

[JohnnieChimpo]

In my ongoing JRSC project, I disassemble and reassemble my blower/intake at least once a month, to remove parts to be modified or upgraded.

While reassembling I'm always looking for ways to make this process easier. Today while I was at the junkyard I picked up Dodge Caravan/Intrepid fuel injector plugs. They plug into my OBD1 injectors just like the Honda pieces except they aren't retained with the metal spring clips. To remove these injector plugs you simply squeeze the plug and it unhooks it from the injector, unlike the fight I currently go through with the metal spring clips.

No power gained just ease of removing the fuel rail.

[JRSC•GSR•EG]

i don't even have clips on mine its been months with no problems, i keep meaning to get some, but hell they have been holding on, i keep checking but they are always where they should be

Guys who are using a LHT or water air look here for a sec.

Who would be interested in a circuit assembly to control a fan for the heat exchanger. My friend is a circuit designer and i ran it buy him.

Basicly it would have 5 inputs.
1 12volt +
2 VSS speed sensor
3 Coolant temp for water temp
4 Ground
5 Rpm signal.

Basicly the fan would turn on once the car is running and the fan would stay on till about 50mph. If the coolant temp goes over 100deg f it will turn the fan on.

Im going to be doing one on my car and was wondering who would be interested in something like this.

[silvciv888]

does anyone have a spare m45 kicking around? i need a few bits and pieces out of it.

[MrDomino]

I wanted to get some opinions from people who know JRSC's pretty well (no noobs)

What do you think about using a hood scoop similar to this to ram air down behind the engine to help cool the supercharger? (Don't comment on how it looks- that's irrelevant)

I think at higher speeds, if designed right, it would shove quite a bit of air into the engine that would help to cool off the supercharger and associated bits and pieces.

I tried to keep it somewhat small so it didn't look too horrendous. (Sorry about the crap photoshop too- I'm still learning).

[JDMCRX]

RCmacdanials had one on his EK coupe you could ask him. Problem is that area of the hood is a low pressure point. It would help pull air over the intake and down bellow the car tho. Water cooling is your best option tho.

[JRSC•GSR•EG]

people at the meets i go always try an get me to put spacers on the back part of the hood to raise it up 1-1.5", i personally think it looks like your car has been wrecked so i don't do it, but has anyone tried it, or notice any real difference in intake air temps or even charger temps

[crxsir1591]

I have a b16 head with b18c bottom end.
greedy ultimate piggy back
two and a half straight trough exhuast
11 pounds of boost
dc sports header
short ram


what plugs should i run and what gap ?
what fuel pressure should i run ?

Well I'm looking to try and max out the JRSC with my build (it's in the planning stage now) and I figured this would help squeeze out more HP plus provide a little greater reliability.

edit: Also, I'm going to use the LHT aftercooler and maybe meth/water in the future once I get the system working and see where I am at although I would prefer to avoid it if at all possible.

[JDMCRX]

Cool.

I am currently going to be building my own water intercooler for my motor next week i get my cores. Im also going to be building a case cooler for the blower to pull some heat out of it also.

The system will feed water threw the heat exchanger to the pump then to the intake manifold and on its output of the intake manifold it will run threw a cooler im going to build that bolts onto the case via the 4 bolts around the intake assembly to help pull heat out of the bearings then a line will pass it over to the snouts side to pull heat out of the bearings there then into the coolant tank on the drivers side front of the car then to the heat exchanger. If it works out maybe ill build a few.

Like stated heat is the sc number one enemy. I know of 2 people with the LHT and it made a huge difference but after some pulls it too can get heatsoaked. The blower is also very warm from the heat of the bearings.

Yeah, right now my build is just sitting on a piece of paper so not much is happening yet. I'm figuring that I'll start looking for parts around November/December and have it working either around Xmas time or spring break time. My biggest problem is finding a scoop to put on there or someone who can do custom fab stuff that can make a good looking and functional scoop. I'm sure there are people out there who are great at those things. I figure if Subaru does it on their OEM cars then it provides at least some benefit.

I figure anything that I can do to help cool the components back there will be beneficial. One question, where does the LHT radiator mount at? I'm kind of limited space wise because I'll have both A/C and power steering.
