How much HP can I run on my eclipse before I start braking stuff. The big thing is my axle and differential. Im going to be using a Hahn Stage two with internal. and Im going to probably be squeezing juice on the weekends. I dont know how big of a shot but as close too 100 as I can. My set up well be as follows:

HRC Stage 2
JE forged pistons, ring, wrist pins
Crower billet connecting rods
AEM adjustible Cam gears.

That is what I have as of now. But I want to his nitrous around a 100 shot. What is going to fail on me? I am also going to probably be purchasing Titanium valves and spring. Im a newbie so go easy.

automatic or manual.

Youll be just fine on stage 2 depending on how you launch, if you launch with the nos your might start breaking axels.

But typically if you stay with stage 2 boost levels, dont have super high rev launches you should be fine.

Most of the stage 3-4-5 guys are fine there are only a few with problems like that , of course they are also pushin 18-25 lbs of boost.


Valve springs arent the problem cause your not revin any higher, sure its a nice upgrade but not necessary IMO

5 speed if it helps... Ok lets change the question too... If I go with the HRC Stage 4... 50 shot nitrous for turbo lag. What would I be looking at needing to change. What else would you change if you were me. What are my risks? Anyone with stage 4 please give me your wisdom.

stage 4+ (18+ psi boost) i would get stage 3 or 4 axels, and either the phantop grip LSD or the Quaife LSD for good 2 tire hook up at the track. I havent heard of many internal tranny issues with 20+ psi of boost...just the small stupid things...your motor will be just fine at 20+ psi if it was built right, i woulndt worry there. Our manual trannies can take some serious shit :P

as far as engine components go the max they can handle is 300 hp and also depending on age as well and as for the axels as long as you don't have slicks and a very hard long you will be fine but if they break they are pretty cheap, like 200 bucks
