RB25 S14 Progress

[NASTY]

I've had this car for a few years and ran it for about a year with the E-Bay manifold and a Holset turbo. I did a lot of research into the aftermarket manifolds like 6-Boost, Full Race, LoveFab, and others and I decided that we could make our own. A friend owns a shop and we decided that we'd give it a shot. We're making a kig off of my manifold so we will be able to make more if anyone is interested once mine is finished and tested. So far I am very impressed with the outcome and am excited to see the end product and it's performance. Check out some pics of our progress so far......

[jlawdet]

clean clean build. car looks great. but i would run a catch can set up or run your crank case vent into your downpipe. that breather will hold oil eventually and you dont want your shit to catch on fire.

[NASTY]

That whole set-up is being changed too, just haven't gotten to it yet. Thanks for the compliments/advice!!

[T-FAST]

Killer job with the mani!

[NASTY]

All welded up now......

[sleeper108]

.... I want your manifold.....

I wish I were as skilled in fab work as you and your friend appear to be.

[NASTY]

I wish I could take credit for the actual fab work. It's my buddies shop and one of his guys is the one doing the work. We all worked together to design it and make sure everything fits/works together but his employee is the one actually doing the work. We made a jig along with it so if you want one shoot me a PM and we can talk about it.

[SinGarage]

Seriously nice work on the manifold. How much will this manifold run for?

[NASTY]

We haven't talked about it yet, we need to test mine and make sure there are no failure points or hicups in performance then we will figure out a price. We used only the best materials so we have high hopes for it's durability. I should have it on a dyno by next week and see how it performs. If there is any interest in getting one of these shoot me a PM and I will give you my contact info.

[!!chuy!!]

let me know how it turns out and shoot me a price! looks sick !!!!!!

[dawagarage]

jolly good work

that's a sexy manifold. keep up the good work.

[jlawdet]

that mani is ridiculous. job well done. keep up the thread, this is a good build. how many hours do you have into that thing now?

[NASTY]

Starting to put the final touches on, new one piece I/C pipes powder coated and new DP.

super clean man keep up the GREAT WORK!!!

[S14Serge]

Amazing work and super clean S14! Good luck with your build hope all goes well.

[jlawdet]

What kinda downpipe? did you custom make that too? the RB swap that I did had alot of fitment issues with the DP because of the steering shaft. are you running a flex pipe section around the steering shaft?

[NASTY]

Car is done and running, we did a very conservative street tune at 15psi and this thing is an animal!! The sound is amazing, the fitment is perfect, and I couldn't be happier with the quality. It will hopefully see dyno time in the next week or so. My tuner is out of town and I just don't trust myself to do it so we will have to wait. Here's a few more pics, I'll try and get some better ones when I have time and it's nice out.

[2F0-T]

i want the r32 in the background of your car in the shop ;) and wtf is that silver car?.. lol

[NASTY]

I talked to the guys today and they'd like to do a limited price break to some of the forum members to get these things out on the market and let you see the quality of the manifold. There will also be down pipes made as well as exhaust systems, let me know if there is any interest from here and I'll see what I can do.


We are working on video and dyno #'s as well. Time has been very limited for us but we will have something soon!!

[Darkvillin]

what kind of exhaust system? full exhaust, cat back, axle back, just down pipes? just curious. great build, amazing looking quality. keep it up and good luck.

[jr_ss]

What kind of pricing are you talking about on the Manifold?

[NASTY]

We will be offering a full exhaust package or you will be able to get the pices individually.

[NASTY]

What kind of pricing are you talking about on the Manifold?

Looks like the first 5 ordered will go for $1199.00 shipped.

[jr_ss]

Do you have any dyno numbers available to back up? Wastegate flange for a Tail 44mm v-band flange? $1200 is a decent price for a beautiful manifold. Is there a warranty? What about flange options? T3,T4, Single scroll/twin scroll?

I think the best idea would be to make a downpipe that will mate with factory dummy cat/cat. most likely a 2 piece pipe. Options to have the wastegate plumbed back in to the exhaust flow?

[japordie]

that manifold is nice, I can not wait to see the dyno reads or footage.

[NASTY]

Car made it to the dyno finally, first pull on the quick street tune Alex did put down 394WHP and just under 300RWTQ @16PSI. We were both pretty surprised how well it did right off the bat. The boost controller gave us a fight and was way too sensitive to get just right so I may be looking into new options here. Alex worked some magic and got the car to hold pretty steady around 18.5-19psi. With some minor tweaking it put down 435RWHP and I believe 309RWTQ? I'm waiting for Alex to email me the sheet, it may have made more TQ. With some more tweaks I'm positive we would have made more but I ran out of injector. The last run had the injectors at 100% so we shut it down there until I get a new fuel system.

A buddy was there taking pics and video but I need to meet up with him to get them, I'll have them posted soon.

[NASTY]

Some more shots of the car, videos should be up later today.

[NASTY]

Couple videos from the dyno, these were all just Alex trying to get the boost control right. I guess my buddy never got any full runs on camera.

[NASTY]

New fuel system and a boost control solution are in the works. Stay tuned for updated vids and dyno #'s!!

[NASTY]

Here are the graphs from the Dyno, I can reconfigure the layout if it doesn't work but this seemed like the best way to show the before and after.

Run 13 is the old manifold and turbo and shows up in blue, Run 14 was the first run off the street tune Alex did on the new setup and shows up in red. Run 31 is the last one we did @ 434RWHP and maxing out the fuel system, that will show up purple.

As I mentioned earlier, we are working on a new fuel system and I will be playing with the Haltech later this week/weekend to get the boost control right. We hope to have new #'s in the next 2 weeks or so.

[HPKMotorsports3]

man that RB is beautiful man... im hating right now

[japordie]

did you do the new setup with the old manifold then with the new manifold to see the bare difference from the manifolds themselves?

[NASTY]

Old turbo and manifold were trashed, it wasn't even an option. The car sat for a while because I couldn't even drive on the old setup.

[NASTY]

Car made it back and did very well. It made 471whp on pump and 19psi and was probably a little heat soaked when it did. I'm sure Alex will chime in with some details as I wasn't there for these runs. On C16 it made a pretty consistent 584whp @ around 28psi and from what I was told was also getting pretty heat soaked. After letting it cool down Alex made one more pull and put down 613whp on the C16. After talking with Alex and looking at the graphs I know this run could have been cleaned up a little and probably would have put down more but the decision was made not to push much harder than that and there were other people waiting in line for the man himself. I'm not planning on pushing this motor any harder until I have my new bottom end built and ready for action. I didn't drive the car far on the C16 tune but the few miles I drive it this thing was a complete animal. It's no slouch on the pump gas tune either.

[eklips3]

applause to you my friend. very nice build.
my buddy put down 463 whp on 16psi with a gt35r , he has it upped to 20psi now so you guys make pretty similar numbers.


i would pay good money for that exhaust manifold, you should get a group buy going, make yourself some money. ;)

[NASTY]

http://i131.photobucket.com/albums/p298/griffinut/S14/C-16.jpg

Run 68 is the new pump gas tune, it was pretty heat soaked at the time but gives you a good idea of what's going on.
Run 75 is the C-16 tune and was also pretty heat soaked but again, you get the idea.
Run 78 is the same C-16 tune as Run 75 but after letting the car cool down a little, as you can tell it could be cleaned up quite a bit and probably make more power but no one wanted to stretch this bone stock motor too far and Alex had some other things waiting for him. I am certainly aiming for more because I am greedy but not until the motor gets built.

[nismo 240sx]

offtopic but wat side and rear you got on the s14

[NASTY]

Here is the first step in the makeover process for the S14, paint and body work coming soon once I figure out what to do with the body then back to focusing on the RB30 build.

Car goes in for bodywork and paint finally next week. My new dilemma is deciding what to do with the wheels. They got scratched mounting the new tires and I now have to decide what color to go with. The car is staying black, should I keep the gold or go with another color? I was thinking about going back to black centers but I'm undecided.

[97nismo]

what does heat soaked mean??

and my friend has an rb25 with the greddy manifold and a twin scroll gt35r and 20psi and it scares the crap outta me revs forever.......so i can imagine you say its an animal lol

When making numerous consecutive runs, especially on a dyno the motor and cooling components of the motor and FI system can tend to retain more heat than they would under normal operating conditions. This causes the motor to work less efficiently and make less power. I can run the car "heat soaked" and make one number, let the car sit and cool down without changing anything else and gain quite a bit. You can see in the comparison of the last few runs that the car gained 30whp by letting it cool off for 5-10min.

[97nismo]

hmm i see....anyways that manifold is very nice just curious as to whether your going to ceramic coat it later on???

[NASTY]

Picking up the car tomorrow, I'll have it for about 5 days before it goes off for more work but I will certainly try and get some good pics while I have it. I haven't seen it yet but I've watched it's progress up until now and so far I'm impressed. Plus Cory from Sinful Creations calls me daily to tell me how amazing it's coming out.

[skyline331]

So cool and great #'s :)

[NASTY]

Holy hell.........Just went to do a final inspection in case we wanted to change something before I pick it up tomorrow. Bumper, Side Skirts, and new lights weren't in yet but this thing looks so much better it's ridiculous. Picking it up tomorrow night and I think Alex(OVRBST) is going to snap some pics this weekend before I send the wheels out and get some other things done.

[NASTY]

Couple quick ones from picking it up, I'll have more/better ones coming.

[kgriffin]

i kinda hate you because your car is where i want mine to be! i think the black centers would look better, but i like the black on black look. what size wheels are those? look a little big for the car. just my two cents. excellent job on everything!!

[RB Me]

ready to sell this to me yet?

[slydin240sx]

Wish my black zenki looked so clean! What side skirts and rear bumper were on it before you went kouki areo? They looked clean flowing with the oem front and lip. Which is what I have, that's why I ask.

[NASTY]

Everything is for sale for the right price.


The previous aero was chargespeed but it was all molded into the car. Wasn't my choice, I picked it up that way years ago.

[killer skittle]

Those brakes!!! i have never seen that type of caliper with a bbk before? Did you make custom brackets or something?

[RB Me]

those numbers are on a stock motor right?

[NASTY]

Bone stock internals on an RB25, in the process of building an RB34 right now.

[dj6923]

Man that car is super clean. I wouldn't do anything else to the body. I love the coil pack placement of the fire wall. One question though. I noticed that the number one exhaust runner is pretty close to your power steering line is it not heating the fluid more than it should be? I don't know the flash point of power steering but I'd rather be safe than sorry. Looking forward to the new dyno sheets and vids. Keep up the great work!!

[killer skittle]

Are those 19s? Superrrrr low pro tires! what did you do for the rear brake setup? Front brakes look amazing!

[G Fo12ce]

Great car. Were the fenders pulled? They look wider in the pics.
