Rep Power: 293

Ok so i am planning on getting rc injectors 440 and a return fuel system to run a little more boost. If i just got the rc 440 injectors would i be safe to run 10 psi daily not always boosting just when racing or showing off to the ladies j/k. Also at 10 psi would we beat a 350z and a mustang gt 2002?

Should be more than enough. Id think they are good til 12psi maybe more, maybe less? I want to know about the 350z as well if we could take one at 10psi. I think we'd have a good chance, cuz I was even with a g35 at 8 or 9psi. I boost 10psi 3-4 times a week. Its been fine on my motor.

I am not sure but would you be pushing the stock internals too far. Like the sleaves or the pistons. I know that the sleaves have flex.

Dam i am really thinking about it Chris I just dont want anything to blow and the guys at my tune shop already think i am crazy running 8 they wanted me to run 6 i think i will run 10 though see how it is. Well i have the bored throttle body the act streetlite flywheel exedy clutch aem pullies poly motor mounts

I was thinking of doing internals but i found out the prices of everything i rather wait about 1 year or more to save up just being boosted then work on internals just the 9:0:1 compression pistons are 600

Ya I feel ya on that one. I have a datsun hybrid 4cyl and I was going to go long rod but the pistons alone for an 82 block and a 78 head are over 500(2 years ago) for ross custom pin position. Arent these d17's kinda cheap?? I thought I saw one on ebay for like 380. LOL you are doin what I would like to do but am too chicken shat. I have taken off the cat and now I am all worried I might be messin up a/f ratio's. Life was alot easier when I was rollin carberated.

10 is definately pushing it. I havent driven my car more than 15 miles in the last month. My cars been busted. You will run into problems, but it can hold 10 psi. anything over youll have major issues. 10 is unsafe as well. To be safe keep it at 8 or less. The first shop that was gonne tune, said no more than 5psi is safe. The second shop had it hitting 13psi on the dyno. They were like, "You have one fast car, it makes some crazy power" haha.

With those mods you are still only good for 8psi somewhat reliably. 6 is reliable, just doesnt have much power, hehe.




Dont worry, youre fine without a cat. It just smells more cuz its off, but your a/f should be fine. dont worry about smoke either. thats from not having a cat.
