Default All motor gsr compression questions????

i have a 95 gsr with alot of miles on it (113,435 miles) however it runs and idles perfect no problems so far, and i am not going turbo because it has too many miles and the hassle of turbo, i want to build the block to make it stronger and last longer because its a daily driver. right now im running high 14's and i want to build just the block and make it a 2.0 (i know that will give big torque increase) and have a compression that will put me somewhere around 180-200whp im thinking compression somewhere in the 10.0-12.5 i dont really know much about compression levels in all motor builds. I want to be runnin high to mid 13's. Is this possible with proper tuning (hondata) if i leave the head stock. if it is possible about how much money am i going to spend. what else will i need in order to do this? (bigger injectors... etc?) i dont want a full out drag car just somethin to be able to daily drive but still be able to smash on any GT and keep up with camaro ss and evo's. any detailed inforation is greatly appreciated.

There are so many different combinations that will meet your parameters.

My advice to you is set a budget.

Make a list of what you have.

And then we can help you out in a more specific manner.

200 whp on a 2 liter block is very feasable with 11.5-1 compression. Some healthy cams (larger than ITR/CTR) I.E. Skunk, JUN, Toda, and the current HT bandwagon cam of the month I.E. Rocket mtorosports, Dynamic Motorsports, Wicked Cams, RS Machines Cams, they are all evidently good.

Of course you will need fuel to support it. Injectors, FPR, Fuel Pump (optional)

More Info will help us help you.

JE 10.5:1 pistons, 84mm bore, stock ctr cams, pnp head, and all bolt on's. 199.6 whp. have been on this setup for almost 3 years now. very reliable street car. oh yeah, also with a/c and p/s!- greaseball

he said it ran 13 flat...i'd say EXTREMELY reliable setup with a lot of room to gain..

this sounds like a good plan to follow, but i would at least go 12:1 and ditch the P@P. if ur not running really high compression the P@P just is not needed. in fact the B series heads in general flow really well stock. P@P on a street setup is just a waste of 1K+. that 1k can go towards something else.

Isnt it the higher your compression is the shorter the life of your motor?
What were you revving at to run a 13 flat and what tires did you run it on?
do you just have ctr cams or did you put valves springs and retainers, i really dont want to put more than 2000 in the head i think with hondata a 2.0 ltr and higher compression, and some cams maybe skunk2 or ctr (i never considered ctr cams before but if you put down almost 200whp they must be tight) i should be at around 180-190 to the ground. What ecu are u using? it sounds like a tight *** setup, i would like to know more.

CTR PISTONS WOULD BOOST YOUR COMPRESSION NICE WITH A GSR

Default Re: All motor gsr compression questions???? (allmtrctr)

correct me if i am wrong but if i used ctr pistons they would not fit if i bored it out to a 2.0. the setup i think im gonna go with is bore to 2.0 liter with aftermarket pistons tune with hondata and go with ctr cams, the only thing i dont know is ehat i want my compression to be, because i dont really know the positives and negatives of high and low compression, i do know that boring it out to a 2.0 will give me more torque. Can anyone help me out with the compression thing and what i could do for say a 10.5-1 or a 11.0-1 compression?
