Well i am planning on ripping my motor apart again since I have an oil burning problem. Anyway, I have a b18c-r and was wondering if I changed out my pistons to CTR one(to boost the compression up a bit) will it be okay to put a JRSC on it? Thanks.

 

Possible? Yes of course. Reliable? Well with high octane fuel, low boost, and LOTS of good tuning than yes. Probably produce pretty good numbers, as well.

IMHO though, if you're looking to go with a supercharger, look into Vortech systems. Centrifugal > Roots type blowers IMO

h Boy...:

 

My question is if it is safe. I will get it tuned of course, but can I throw in the CTR pistons in and run a 12.0:1 compression and then bolt on thr JRSC for the ITR and not have problems?

Why in the world would you do that? ITR's stock compression is already almost too high for boosting on pump gas.

Should I not attempt this then and go another route?

 

High compression and boost!

 

Is it safe?

 

Management is key...

At the same time, not tryin to beat a dead horse, all it will be doing is spending money that isnt needed to be spent. Look on SGT's site some at the power made from some of these all motor setups.

Youll be much happier IMO.

Stunna- Whos b18c1 kaa used to love testing cars with the jackson...

 

So as long as it is tuned correctlly I should'nt run into problems? Thanks.

 

Not exactly. With a JRSC you have very high heat levels. Do more research b4 you do this, please.

You're wrong. Dead Wrong. All it leaves is less error space for tuning. That's it. Take it to a good tuner and don't do a half *** tune and you will be fine. There is NO need to lower compression...that is an old myth that needs to die. It's been proven to be wrong many times. Just let it go.

 

Kaboom! look what happened to #0688.

 

So far there have been 3 responses that are equivalent to talking out of one's ***. If you can't tell which 3 are the bs posts, then you need to step back and research the issue yourself before inviting every village idiot to give you his opinion.

Edit: While I was posting this, #4 reared its head.

 

is the vortech supercharger carb legal like the jrsc?

 

i have the JRSC on my ITR

at 5.5 psi on STOCK compression, i get detonation

CTR pistons will **** your car right in the ***, hard!

if you want to know more about the JRSC on an ITR, i have experienced it all and realize what needs to be done and how to do it

it is WAY more involved than you even know

 

What recommendations do you have before I do this. Thanx.

 

what kind of boost do you want to run?

what mods do you currently have?

Don't do it.

Well, right, there is NO need to lower compression. I run 10 PSI with stock 10.5:1 compression.

But why run 12:1? Seems like a waste of time and unnecessary risk.

I don't know many people running higher than 11:1 compression with boost. Not sure it's been 'proven many times'.

-Chris

 

I have 96 ITR with Spoon rods and pistons, Skunk2 valvetrain with stock ITR camshafts, Toda header.... nothing to wild. Just wanted to know if this was possible is all.

Why 12:1? A few reasons...

-More power
-Better low end (when you're not in boost which, in turn, makes it a much more feasible daily driver
-Why not 12:1?

The reason you don't see many people running 12:1 is because of thinking like yours (no offense man). People like to hold onto old myths and they like to listen to Honda "tuners" who really aren't knowledgeable.

 

It probably is OK... but if I was starting from scratch, I'd leave the compression stock.

-Chris

 

I'll keep you guys updated with the project. Im going to try it.

I agree. I would never lower it though. It makes off boost driving more of a challenge.

I would sooner raise my compression than lower it if I were going to boost but maybe that's just me. *shrugs*

Diminishing returns.. at .5 bar the effective CR would be 18:1. Not many n/a guys are running 13+:1 on pump gas, let alone 15 or 18:1.

Your motor will be more efficient, but you can only compress gasoline and air so much before it ignites itself on any little hot spot you have inside the combustion chamber. Not only is it more volatile at high pressure but it will get hotter as you compress it.

Good luck with the project. I would highly recommend tuning to control both fuel and timing (i.e. Hondata or equivalent). King Motorsports and Whip Factory are two good tuners in the area that do Hondata.
