How do you propose controlling these massive injectors? Sell them to me instead.

if u break 300hp i will give u a nutsack that hangs off your diff, u dont need larger inj for stock turbo its a waste and on top of that u need something to controll them, u will probally LOSE throttle response with stock turbo and that huge TB, normally i type in something stupid followed by IBTL but i dont feel good i was drinking last night

Yeah 300 at best. Turbo is limiting factor.

A T3 at 20psi? What A/R exhaust housing?

You guys are SOOOO mean! Seriously, this guy is coming her asking a serous question, and all you do is berate him!!!

keep em coming, I enjoy the laughs..

But seriously. Maybe 300WHP? 20PSI is pretty ridiculous on a non-prepped motor. Look into at least prepping the head, new HG, and ARP studs. Loose the 90mm TB and look into an EMS.

20psi is retarded on a stock turbo, not a stock motor. There is no reason to change the headgasket for 20psi unless that 20psi is coming from a T88 or something. It's about HP levels and tuning, not boost pressure.

Flex downpipe? Please tell me you don't have a downpipe made from flex section!

Seriously though.

Ill bet you gain jack squat. Why are you doing all these bolt-ons and still on a stock turbo.

Wow, never in my life have I met people such as you people. I come to this site, being told that there are good people here, and I get 12 posts of people defaming me? Awesome. If you guys would read correctly, I DONT have the aftermarket turbo YET<< < < < < I never said I was going to run on a stock turbo.

And for the other guy, I have a FPR

I never assume anything. I was theorizing on "what estimate with t3 turbo at 20psi".

Which is why I stated

You gotta have pretty thick skin around here, especially if you are going to ask questions like that. There is tons of info on this website alone, not to include other forums, such as Skylines Australia. But you really need to at least try to search first. The thing is, you would get tired of people coming up to you asking the same old questions all the time.

Don't take it the wrong way, we are just giving you s#%t. Why dont you take a deep breath, and start over again. I see you have a stock RB with some bolt-ons. Who are you? What are your goals with your car? What is your experiance level? Introduce yourself to the Forum! And don't forget to SEARCH!!! Welcome to Nico.

I don't even live in Council Bluffs and know the cops are a-holes about speeding/traffic. You should know better than to pull up next to a cop and let out a long downshift. I can see how it would easily be misconstrued, but the cop has jack $hit to prove that it was your intention to race him. You should be able to get off the hook unless you're not telling us the whole story.

Back on topic, you initially asked what hp you could expect out of a stock turbo and a T3. I answered 300HP for the stocker and asked what exhaust housing on the T3. Other people said the same thing. I don't see how those replies didn't satisfy you or made you think they were d!ck comments...We know nothing about your engine's internals or your experience with the RB's, so introduce yourself and fill us in. It's tough love in this forum, but it doesn't take long to learn the ropes.

lawl at the tacky $20,000 upgrades...

those taillights is worth at least $5000 cause they're so JDM rare...not to mention the GTR badge is worth like another $5000 cause it makes your car look like a JDM TytE GTR!!! The other $10k must be spent in that stock rb25.../sarcasm

Seriously you're going about upgrading your car in the wrong order. Putting too much money into things that don't matter yet. Ditch the taillights, crappy gauges and crappy decals and maybe people will start talking to you seriously.

You know what...I think new members that join this forum shouldn't even be allowed to post for like 2 weeks. I remember joining and barely having to post anything, cause everything can be found through search or stickies. I actually didn't join this forum for the longest time ever, but was still using the forums for information. Point is don't ask questions unless you REALLY REALLY have to, and when you do make sure the question is worth it, or else you'll just get scorch like you have here.

You know, you sure do have a lot of pictures of the outside of your car on myspace (and it's ugly BTW) and NONE of the supposed RB25 residing under the hood. I think you don't have an RB25 and are just trying to make yourself feel better about your riced out "whip".

2Fast2Furious=Love!!! Yeah, you a real gangsta from da mean skreetz of Iowa yo.

Thats why i dont have too many posts. Half the time I post a question, then go back and read it and I'm like, that was a stupid and/or gay question, search a little harder and find the answer. Remember, GOOGLE is your friend, and now the SEARCH button is big, red, and flashes!!!
