already here is the deal i want to build my block to withstand like a 150-200 shot on my block with the low compresion pistons and shit like that but what i am wondering is if this is going to effect my speed for when i dont want to spray and how much use am i going to be able to get out the block before i will have to rebuild it again. i dont really know alot about nitrous builds so any help will be good. thanks

thanks alot that helps alot, people were tellin me that i need to go with low compression pistons to handle that size shot but i guess they were wrong. But now i have another question. i was lookin at pistons today and i found some forged Mahle pistons and i was readin about those and they said that u dont have to sleeve the block for these pistons because of their material but i was wondering what kind of shot you all think they could handle and if you all could point me in the right direction in getin to my goal on getting a 150 shot.
PS. i sprayed my car with a 75 shot today and it was naaaaassty

To answer your question low compresion motors are pigs without any help you'll be alot slower, you should pm 4nmusle he loved nitrous for years.

when you are ready to sleeve give me a call. what year motor is it?

GaRn

go with 11:1 compression ratio and a shot on top of that.. just tune conservatively on nitrous..

Jester_Si

what he said...there is No reason to run low comp. I have seen 12.5with spray......

If you want to spray that big of a shot, You will need forge internals at least. Pistons and rods. Also go high compression not low. Nitrous like high compression. Should sleeve it to be safe, or at least run a block guard. They are much cheaper than sleaving and an easy install, just not as affective. And this is probably a give, but make sure your using a wet kit with that big of a shot. And tuning will be they key.

The Mahle piston thing is/was a huge debate, several people have tested the car with negative results, some with good.. Just go on honda-tech and search your little heart to death..

IMO I would just sleeve it anyways..
