Need some feedback, my quest for 450 rwhp (MATAfied's RB25 project)

[matafied]

Well I’m getting closer to finishing my garage project and have been thinking about my goals. I really just want to have a well rounded car for ounce in my life, and not just something that looks like something off mad max but will outrun the local cobras (my daily driver). I would like to put down at least 450rwhp to be satisfied but not sure what else I’m going to need, so here's what I have

S1 RB25DETGreddy intake manniQ45 throttle bodyQ45 mafGT3582R I .70 a/r E .84 a/r from atp turboxs power front mount 12 by 24 with 4 inch core3 inch Intercooler pipingGM ignitionHKS spark plugsHKS SSQV bov850cc side feedsWalburo 255 ( going to replace with a bosch 044 )Adj. fuel pressure regulatorGreddy Profetc B boost controller and turbo timerApex'i Power FC with commander and datalogicInnovate LC-1 Wideband 3 inch full exhaust n1 muffler

So how much boost am I going to have to run to get me to 450? Also how well do you all think this combination is?

I am open to any and all feedback

oh and i almost forgot i need my harness Carl

and also my maf isent going to be that close to the turbo inlet, just stuck it on there to keep it out of the way









my daily pile of crap but i can say that i get to drive a rb car everyday

1st of all: looks super nice!

2nd: What clutch are you running or planning on using?

As far as suggestion I say a set of nice cams in there might give your car that extra "uphf" if you know what I mean, but its not nessarrary to get to that magic number.

Overall, looks good man.

[duece.four.oh.sx]

no power steering ......sweet time to start building those arms so far i think your just about there but like coolwhip said some pair of cams wouldnt hurt......

You will probably have to run over 20 lbs of boost with the GT35 to get 450 to the ground. Plus I hope you have some 10s out back for traction. I really like your ignition setup. I might be copying you in the future.

[matafied]

Thanks guys

Plus I hope you have some 10s out back for traction

Im looking at some work cr kai's what would you recomend for the offsets and tire/rim size??

I really like your ignition setup. I might be copying you in the future.

yea it has worked out awsome on both of my rb's, only thing is running the power from another source (relay)

oh and im used to no power steering been like that for 4 years, but i do plan on installing it

F 17x9 lowest offset possible. R 18x9.5+15

if u have coil overs.

[matafied]

yea i have a set of tein coilovers

I had a set of Racing Harts on the rear of one of my old S13's with a 18x9.5 +17 might be able to use as a reference, when i get home I'll get those pics up for ya.

[240z4u]

If you plan on racing at all, some sort of drag radial on a spare pair of wheels.

I have 18x9.5s out back with 275/35/18s and have absolutely no problem spinning them from a roll anywhere in 2nd gear. They are pretty sticky pirellis, my winter tires are a 225/something/16 kumho. The spin like nobodies business.

Big power is not nearly as much fun if your not hooking up!

[s13point5]

what exhaust manifold is that?

[matafied]

i knew it was comming

its a matafied ssac, just for now haha

[s13point5]

how did you modify it? because the SSAC manifold i got, when i mounted it to the the head, my GT35R hit my valve cover. hell if the VC wasnt there, it would have hit the cam. even the stock turbo hit the valve cover

[matafied]

i cut the flange off the manifold, expanded the inside of the opening. welded supports, then put the flange were i wanted it, welded it on and then reinforced it.

[rbosacco]

whats up with the internal gate. i know you don't need a external but i'm just curious why you chose that route because the ssac manifold does have external provisions doesn't it? just curious, looks cool overall but that looked out of place.....

[matafied]

yea just was trying to keep the exhaust simple, i was going to go the other route but idk, we will see how it works out.

[matafied]

well i got my suspention on, along with my 5 lug and z32 brakes. intercooler was a breeze with the s13 front end, so all i need now is my harness got a couple pics of my 3erd swap also ( brother in-law) super clean hatch, should be driving it for the first time this wensday

[midnightsliding]

haha i think u live in my friends old App. complex, looks like its and i always seen a s13/ and 86 siting near the entrance.

[matafied]

haha yep i couldnt keep the 86 because i had to many cars, had to crush it sooo shhhhhhhh! i have to change the rearend and convert it to 5 lug also, hopefully i can have that done this week

[DriftVaginator]

Nice build your progress looks very good. BTW you mentioned you where looking for Work Cr Kai wheels, and i have a set for sale. Specs are 18x10 all around with +11 or 12 offest i can't recall specs exactly. They are like brand new. Let me know if ur intrested.

[Darius]

wow you better have 50mm overfenders for those bad boys or risk looking like a mexican low-rider!

[matafied]

yea i dont think the 18 by 10 all around is gonna work for me

[Chaos the Xile]

I made 467 on 25PSI with a log manifold, tapped for a 38mm wastegate.

[matafied]

sweeeet 467! man i will be more than happy if i can get that

[nzmoman]

yea i dont think the 18 by 10 all around is gonna work for me

I'd still go for that set. You can run two in the rear with decent street tires and then decide on a drag radial for track or late night cruising. But of course you would have to go find another pair for the front.

[Cjmartz2k]

I just noticed a lot of you guys are in the Triad. I used to live in Kernersville and tear it up down in High Point on N. Main St. Do they still do that?

I need to get with you guys about what's going on RB wise in the Triad to help me decide if I'm going to try and Grey Market the Skyline back there or just take the drivetrain back. Sorry for the thread jack.

[matafied]

still waiting on my harness from carl

[bumblebtuna]

how long's it been now?i'm waiting too 3 months and counting

not disrespect to carl, he seems like a great guy..but damni would've gladly paid more to have mckinney or syko do it if i knew it would take this long.

[matafied]

DRUM ROLL 7 months like you said no disrespect but dang! My turbo is rotting away! And I get to hear my buddy’s tell me how my car has more miles on it from pushing it than I do from driving it. Oh and the real kicker is their driving their Rb cars because I did their wiring
