how much did the pistons help you?

i'm thinking about not putting them in and going turbo, but i would like some input on the pistons being used in a gsr motor first.

that right there is a NO...
comp is raised up u want to lower your COMP if your going to boost it

 

actually, i was going to keep stock compression and boost the gsr motor.

i'm thinking with the set up i was going to do withe the b16 pistons, i would get roughly 170-180 whp.

if i just use some stock usdm pistons, my compression would be 10.2:1 and with 7-8psi, i should see over 200 hp.

 

I use them in my GSR block currently, but I couldn't tell you how much power they made specifically.

With 7-8psi, you should see well over 200whp w/stock compression

 

sorrry my misunderstanding, i was reading it wrong. it depends on what you want out of the car? if your goal is 200 stay NA.
NA is ons of fun when done right, oost can be fun as wel but more parts= more things to go wrong

did you feel a difference though with the b16 pistons? do you think they gave you more hp's or just higher compression?


i had a turbo ls motor in my eg hatch before. its not more parts, its just one big bolt on kit. like putting a header and a big intake on, nothing to it.

i think that 200hp will be just too hard to get N/A, especially with what i got, so i'm looking at boosting again.

 

b16 pistons will give you higher compression.....lots of guys do this when they slap on a b16 head on their gsr blocks to make up for the loss

The bump in compression should yield more power. If your goal is to hit 200whp, I would suggest bumping the compression to get there. It's an important factor.

 

yeah... but i would have to do a lot more than just bump up the compressor.

or just throw on a turbo kit with stock compression, get tuned and be over 200whp.

 

if you decide to swap out pistons, are you going to be running stock cams? either way na or turbo is gonna be fun to drive in a hatch. good luck on your setup bro.

 

if i put the b16 pistons in, which i don't think i'm going to now, i would sell the CTR intake cam i got and upgrade cams. i would need better cams to go all motor.

from the looks of it, i think i'm just going to put some usdm gsr stock pistons in to keep the compression and 10:1. that will allow me to boost the motor and my compression won't be so high.

 

sounds good....
keep us updated once you slap a turb on and tune it.

 

Why dont you just go forged low compression pistons? Turbo loves low compression.

Again, compression is a factor, it's one piece of the puzzle when you're building a motor.
If you're more interested in hitting a specific peak number on the dyno, a turbo kit would be the easiest. You should have no problem at all reaching that peak number with boost.

 

buddy of mine has b16pistons in his lsvtec with gsr cams and this thing is nasty all the way til it pegs 5th gear

 

yeah... but b16 pistons in a gsr motor will not be good for turbo.

i think turbo is the way i'm going to go.

yeah, it may be the easiest, but oh well.

I wasn't saying that as a bad thing, simply stating that it's a much easier battle with boost, to hit a high peak number on the dyno, if that's what you're after.

Actually, the turbo will spool a hell of alot faster with higher compression. Im not saying 12:1 or anything, but stock compression is great for a low boosting street machine. If you leave your internals stock you can run around 7-9psi all day with a decent tune... I'd reccomend you get a 255 fuel pump and some bigger injectors tuned with some hondata... That thing will MOVE.. A friend of myne managed a 12.6 at a high altitude track on 9psi on his bone stock JDM gsr motor with stock injectors and a stock ecu... and that was in a full interior 95 Civic EX Coupe.

 

Yes it will make it spool faster...Well it depends... ur risking the durability and the longevity of the motor. The size of the turbo also matters; if you are only running 7-9 psi go with a smaller one to get the full potential of the turbo.

 

Dude do me a favor, don't boost on stock pistons you know very well that your going to end up braking the ring grooves, your cars going to be smokin. Then your going to be like damn I should have used a forged piston, just trying to save you some time. Seen it happen way to many times to countless people. You could get a good look at a piece of meat by sticking your head up a bull's ***, but wouldn't you rather take the butchers word for it.
