ok so i went to the dyno yesterday and i want to know some opinions on the power i made, i think its kinda low for this setup but i want to know yalls opinion. so i made 775 hp 636ft/tq on 27 psi. power band is from 5200-7500 rpms. i will post the graph up tomorrow when i get to work. but heres the video of the run, i had to stop n couldnt do any more until i get better boost controller and fix my radiator spill that happens on only on higher boost.

thanks, i have kelford 272 with 10.55 lift. hopefully if i can get boost controller working or get a new one by this weekend, i will the car dyno'd

man that sucks...

well thank you sir. yall really do LHD conversions??? Hopefully if i can get this apexi boost controller to work i can go to dyno in 2 weeks and results see if they are good for my mods.

no not going for your so cool. just letting people enjoy seeing other peoples build, everyone has ideas of what they think is good and not and wanted see everyone opinion on my car.

so i have run that i did while on 15psi tune. what you guys think on this. sorry in advance on the first for for camera

yea that would be cool but not for a street car tho.

I have made a spacer for the hood for now but I'm thinking of making a cool looking scoop for tho. What you think?

ok so i have an update on my build and wanted to share with what it looks like an sound like. lmk what you guys think on this build so far.

from the silvia.

im thinking bout having the old manifold redone but imma take it a really good welder an see what he thinks.

please go to my blog im having some issues that i need help on. like my turbo is not gonna fit by a long shot so i need some help with some bright ideas. Check out the progress on my RB26/30 http://j2fast.blogspot.com/

so here are some pic of the process these are some before pic when it was an rb25 500whp this what happen to the car when the 6th pistion blows. here is some pic of the new block rb30 this is some pic of the head and diff in the porting here are pic of the RHD conversion here is the borg warner s372r that is going on the car

i In the states it's not that easy. Here these cars are highly illegal, so customs will sieze these cars as soon as they cross over here. You cant bring them over in the full car, so thats why you usually see them chopped in half. That's why we only get front clips. People who have these cars are getting them taken away by the government and they get crushed.

well i just wanted to share my build with my fellow RB peps. so not only am i building the motor but im also doing right hand drive conversion aswell. for the most part the RHD is complete well the body part but still need to do the wiring, the motor is coming together. im doing rb30 which its gonna be 3.1L with big turbo(S372) 1000cc injectors dual fuel pumps on E85. Full over haul, 1mm oversize valves springs retainers, port and polish. i have a blog i started so ill keep that updated aswell this post when get things do to car. my goal is 700-800whp. hopefully this will do good and last long time. the site is http://www.j2fast.blogspot.com

i think the .84 would be to small for my application, but im using it for highway runs and to like mile runs to top out the car hoping to break over 200mph in a mile.

its not about me not wanting to get a better turbo, its about im getting this one for free until i get another one. i know i should expect lag, but im asking which AR is better for level of power im looking at with the stuff i have

hey guys, well im in the process of getting a new turbo (the t72 blew) and i came a cross a free good condition turbo which is a precision t04r turbo. the only thing is it doesnt come with the hot side. so my question is what size should i go with? my motor will be completely built (ex. pistons, rods, valve train, 272 cams, port and polish) now im trying to make close to 800whp as possible with this turbo an i was thinking about getting the 1.15AR but didnt know if that would be way to laggy on this rb30 are not(i came from rb25). i will using e85 aswell for my fuel to high boost is not a prob im trying too aim for about 29psi as my high boost. i tried to look online but most post dont have results with the AR on it to compare. im not looking to get another turbo just needing help with this one to maximize my power from it. thanks

yes, i know it can handle it but its just like porting the head, its good up to like 700/ 800 hp but it will make a better power graph if ported out.

i wanted bigger ones for more air to inter the head with my bigger cams

im looking for bigger itb for my rb30/26. here in the usa theres not that much for the skyline so i fiqure someone overseas would know if someone makes something like that are does people just switch to single? lmk what you know about this. thanks in advance
