I had my motor rebuilt with some stuff done to my motor including 11:1 type s pistons. Cars been running good and all but I just starting to feel like jr supercharging it. I was told I can supercharge my motor with the type s pistons but i'll have to really tune it out. What do you guys think?? I'm just thinkin bout it. Not sure if i'm going to or not.

 

frm pistons are notoriously bad for busting ringlands at 10:1 on a JRSC, what do you think will happen at 11:1?

 

why would you want high compression pistons with boost? you've got it all backwards

put your stock pistons back

 

no no no. I know low compression is better for boost. I was just wondering about the 11:1 compression with supercharger. I didn't think it could happen, just that someone said it could.

could I use a little shot of nos with the type s pistons?? 30 shot?? haha I'm just looking for a lil more power.

 

it could happen. wouldnt be really safe/reliable and most likely wouldnt last you a long time before something blew.

What are you talking about?? you still want lower compression if your going to supercharge also... and your nawzzz question again here it'd be better to have the stock pistons but can be kinda safe with the pistons you have. you need to so a little more research. and stop lying that someone said it would work, you know it was you that tought it would work jk

 

Research it more. You don't know too much about it, so don't make any decisions yet till you read up on it.

If you put a supercharger on your motor, you might as well put a blindfold on the headlights and a cigarette stickin outta the intake. The motor will pop. A little nitrous would be fine, though, if taken care of properly.

 

give me ur type s pistons and il give u my stock pistons and then u can supercharge all u want :D

 

There was a guy from Houston running a JR kit and 10.5 jdm pistons, he has like 258 WHP @6psi. Everything was going good till he missed a shift and well.........bent like 8 valves. Other than that its possible. You could get a 9psi pully and put it on the other side of the jackshaft and run like 3-4 psi..

 

back from the dead......anymore thoughts about running a JRSC with type S pistons?

 

Go to the Forced Induction section and read the "What JRSC set-up you running" that should help you alot.

 

superchargers are ok on high compression. but u really need it tuned. u could make good power. u would need lower compression for turbo tho.

 

thanks...i'm really consindering doing this. I will be tuning with neptune. I just wish there was a was to cool down the intake charge....

 

not really sure. i have thought of doing the same st up. but no superchargers 4 the 4th gen

 

Unless the architecture of the H22 has changed from 2004 to 2007 I would expect the same results. Your ringlands will be your downfall.

Do you know why ringlands are the downfall? Why would want to use stock usdm pistons over type-s pistons for a supercharged application. Please explain


Ever think that maybe they were wrong in 2004. Now with it being 2007 nobody still can explain why other then it wont work because I read or this guy says so but i have never actually done this myself.

I would explain my reason for this but its just going to start a big fuster cluck. I'll wait for a few replies and decide from there.

Edit: I'm just a stupid ricer who doesn't know anything anyways. Please disregard my comments above I am sure I don't know what I am talking about.

 

well when you detonate your motor, you can give me the pistons that aren't damaged. if any.

 

My friend makes insane power out of a high comp ca18 turbo setup he's got in a 240, but high comp in a nissan is like 10:1. High comp boost of any kind makes a lot more power, but it's also a lot harder to tune and without good tuing will end up breaking things faster than normal or low comp.

So because you have 11:1 over 10:1 the motor is going to detonate. Sounds like tuner problems to me.

Let me guess John d is also right in his old post saying its better to run the usdm pistons over the type-s also

 

11:1 comp ratio is VERY high for boost, ideal is 9 or less :1, the chance of him detonating is way more probable, even with tuning if there are air temp differences, air pressure differences, elevation differences..you can blow it up really easily. The higher comp ratio just magnifies it.

Turbo is one thing and will agree on that statement as far as turbo applications go. Supercharged applications and N20 are another especially N20.

Yea they do differ, as far as blowing things up. Instead of grenading your IM on your block you just grenade the S/c on your block. There is no difference with forced induction turbo vs s/c only the way the boost is delivered. If you have nitrous you better make damn sure your fuel system is up to par.

 

i still dont understand why you would want type s pistons in a FI car...doesn't make sense to me.

id like jdmlude5 to explain this one to me.

i dont think hes a very reliable source, however, he could tell you how to put Motegi MR7s on your car and maybe even altezza tail lights! JDM YO!
