Hillclimb S13 update

[driftstyre]

Some updates.

I finished the chromoly motor mounts and installed a spare block and head in the bay. I am almost finished the exhaust manifold for a twin scroll td05hra mhi turbo. The tubing is 321 065wall and should be fine for mild to moderate antilag (for 2-3 minute runs) The manifold is 2 piece with the second half slipping on and providing enough for heat expansion. The turbo/motor/transmission are all solid mounts. The bracing in the front end is no where near completion and I am waiting on some .5 inch tubing to finish up and mount a bumper.

The compressor-->intercooler pipe will be less than 1 foot and the post IC pipe will be less than 2 feet. Sunny throttle bodies are mounted and the plenum is almost complete. Intercooler mounting will be next, then coolant lines to the rear and radiator mounting.

Oooh. Sweet set-up. More pics!

[Var]

Dude you are insane. I like your work. Keep on fabbin'

[drifter808]

mean da dope! that thing is gonna be awesome when its all done. post some more pics

[HyperTek]

so the motor mounts are super solid, and the turbo is also bracketed?

[driftstyre]

the motormounts are 049 wall, heattreated 4130 as well as the front brace. The turbo is mounted to the chassis as to eliminate any weight strain on my fragile manifold. Any vibration will be absorbed by the slip connection (which I will do over break when no customers are around :) ).

[Loofee95SE]

OMG!! I have no words of expressions............C

[NemeGuero]

SEXY AS FUCK.. that thing will EAT mountains. Haha.. ITB TURBO... I've wet myself.

[Flybert]

What are your plans for the tension rods?

[go240]

wow, that's some really sweet work. nice job

[young gun]

nvm .............

[Nan Desu Ka?!]

wow, awsome fabrication man! i have never seen ITB + turbo setup. i have a question for you, and it's only becuase i have never seen this before, how are you getting the boosted intake into the ITBs? i assume its going to be all custom piping, but i cant really picture it in my head. anyway, it looks like a beast and i cant wait to see it done so i can stare at the engine bay and figure it out myself if you dont end up answering this.

thanks, and again, it looks absolutly amazing! good job!

[orion::S14]

To answer for the original poster...like the GTi-R, there is a plenum that bolts ONTO the plate behind the 4 individual TBs...so there is one inlet, and standard intercooler piping.

Only real difference is that instead of one TB at the front of the plenum, you have 4 inside the plenum.

- Brian

[driftstyre]

Thanks for the kind words everyone.
I'm not using the GTiR plenum. From the throttle bodies out it is all new. The GTiR doesn't have velocity stacks. I will finish it tonight and post some photos.

thanks, that clears up most of it, im sure the pics will explain the rest. i cant wait!

[wootwoot]

wow, awsome fabrication man! i have never seen ITB + turbo setup.

You've never seen a rb26dett or a sr20det gti-r? Also see, turbo charged/supercharged BMW M3's and sportbikes

[luckyrb13]

Is this thing gonna be your Grocerey getter. :eek2: Honestly makes everything ive ever done to my car seem pittiful. keep up the good work.

[Nan Desu Ka?!]

nope, i guess im sheltered. woe is me. at least i now have some search fodder. thanks! my search button is gonna be abused later tonight when i get home from dinner. im very curious to see this kind of setup on an RB... Mmmm delicious.

[NemeGuero]

It won't look like that. the 4 ITBs merge into a large 'plenum'.. like this guy WILL have.. and it'll look basically like an aftermarket intake manifold.

[EchoOfSilence]

an equal-length plenum for the ITB's would be orgasmic, but then again I am talking out of my ass

[xamS14]

hmm how bout 4 turbos. slap one turbo up to each TB

[sideview_180sx]

that front bracing is awesome to the firewall. what diameter tubing are you using and what steel?? dimple die goodness.

[driftstyre]

the cage is 1.625" 083 wall chromoly and the rest is 058 wall 1.00" chromoly. The suspension will be made of 058 wall 1.00 as well (with stock subframes for now)

[scir16v]

I want video of this beast running when it's done and competing

[papa]

love it...keep us posted

[driftstyre]

I finished the exhaust manifold and am waiting to mount the intercooler before I finish the intake plenum. The exhaust manifold will have to be redone at some point as I don't anticipate 321 lasting that long being blasted by ALS. I'll have to save up for inconel or 347.

OMG. That is pure SEXINESS. Jizz-worthy!

:wackit:

[big_schaf]

Nice work, cant wait to see the final result

[kaje36]

very good work bill.. I am definitly gonna have to come down to your shop some day this winter, and watch ya work on this beast ! and definily come to a few of these races

[NemeGuero]

Damn, I love the fabrication. Do you flow-bench test your stuff? or are you not really concerned with that?
With the exhaust mani, you ran 4-2-1?

good stuff..

[90RS13]

With the exhaust mani, you ran 4-2-1?

Not quite, it's a twin scroll turbo. The inlet to the turbine is divided.

[driftstyre]

4-->2 as equal as I could get them. I tried to measure the runners as well as possible to keep them equal but by no means is anything flow tested (or tested in anyway for that matter). Hopefully it will be in the spring sometime :) I'm curious as to what a long runner turbo SR will sound like. Probably raspy.

[Nan Desu Ka?!]

WOW. that clears up a lot of my questions. not only that but OMG its HAWWWWT!! keep up the awsome work, i really look forward to seeing this project completed. its like nothing i have seen in a 240.

[Sil Beer S13]

That is awesome fabrication work!!

[EchoOfSilence]

why the twin-scroll, though?
and how will you go about the anti-lag system?

i'm curious

[driftstyre]

I am just going with a turbo that happens to be twin scroll. The td05hra is designed specifically for antilag. The next cheapest ALS turbo is a T35 Garrett w/ maram 247 shaft/wheel. New they run close to 4000. After that is the TR30R at close to 10K a piece. The HRA is 900 new and readily available. It happened to be twin scroll so I designed the manifold accordingly. With ALS I should have a 2-7000 rpm usable powerband. Autronic or Gems will be used with a mil spec harness. I'd like to use AEM because I love it and we use it on our other hillclimb SR but I'm not sure about the ALS capability.

[luckie2hav3her]

so wait...wheres the clutch and brake cylinders gonna go??

[driftstyre]

I have a wilwood pedal box that is mounted right behind the firewall.

[meatish]

I have a question: What is your budget for this car? How much are you planning on using it?
If you are willing to run anti-lag on a $900 turbo then you have my respect, but I cringe at the cost of replacing it after a few thousand miles.
As for the runners, looks nice! Also, is that the intercooler you will be using when you race?

[chibo]

Wow, this is definitely something to watch as it progresses.
*stabs F5 waiting for new pictures* :)

[driftstyre]

I'm not worried about 1000 miles on the turbo as I will probably put less than 200 miles a year on the car. The turbo I am using is designed for 500+ miles of very aggressive antilag. It will be fine.

There is no budget. I am poor though and have been buying parts for it for about 3 years. Total with ECU it will cost me under 10K. There is over $15,000 of labor though.

Is that the Yacco sponsored 206WRC in your sig.?

[TUnity2]

wow man, beautiful work, the more pics the better :)

[NemeGuero]

and more pics of the pedal box?

[papa]

amazing work..deff loving the fab work

http://www.dentsport.com/bill240/manifold_new2.jpg
i like the plenum-to-velocity stack idea, but won't having the stacks poke out that far into the plenum cause flow problems??

[driftstyre]

The intake manifold is done.

[blackflag_Rms13]

Damn looks great man! When do you expect to finish?

[EchoOfSilence]

haha good old AP racing.

so did you move the plenum farther out? or are the stacks still poking in?

[meatish]

Is that the Yacco sponsored 206WRC in your sig.?

Haha yep! Another rally fan, i see. I like your work, keep it up!

[driftstyre]

Meatish,
Check out some pics from Rally GB 03

[NemeGuero]

The intake manifold is done.

Nemo, here is the pedalbox

Damnit it's NEME as in NEMESIS or Guero.. pic one, Not a hybrid. LOL

anyway, back on topic. How are you going to mount that pedal box? On the cabin side of the firewall? Won't your pedals be really f*ckin' close?

[driftstyre]

I'll post pics of the pedal setup in a little. My seat is about 10 inches further back and 6 inches lower than factory mounting points.

[EchoOfSilence]

boo I wanna know :cry:

[driftstyre]

Just a few more updates...the drivers seat is mounted, the pedals are positioned but not hard mounted yet, the intercooler is mounted and the end tanks and piping need to be finished. I am waiting for a couple of parts to finish the steering column. My dash mold is complete and will be going out soon.

[NemeGuero]

Good shit! I only counted 2 pedals?! And what power plant is this? I could be blind but I didn't see it mentioned.

[driftstyre]

I had an s13 thottle pedal sitting around and somehow it disappeared. I just need to stop by a junk yard in this 20 degree weather and grab one.

I will be using a semi-built SR with stock rods/crank, ARP rod bolts, head studs, mahle pistons, not sure on cams but most likely 256/264. 1.2-1.8 bar of boost will be used on 109 unleaded.

[infinitexsound]

bill planning on usin some bike brake cables for the gas pedal ayy??? lol
how come u just didnt mount the ap system under the dash?

[driftstyre]

The mold for my carbon dash is complete and I will making it next week. The rear lower control arms are awaiting monoball assys, then a few gussets. The intercooler mounts are complete, piping is in progress. some pics:

[240trainee]

Wow dude, amazing project. I like the pedals, I've been wanting to re-do my pedal assembly just as a challange, lol, always has intrueged me. Coolness.

[driftstyre]

http://www.dentsport.com/bill240/rca_finished.jpg
Well, the rear arms are finally done. On to other stuff.

[Loofee95SE]

wow, man, i wish i have half of ur skills and dedication..mad prop to u. can't wait to see that thing become alive. C

[locodrftr]

is that a blacktop sr ?

[kuramaya]

great prgress reports...I bet that thing will be one of the most structurally sound S13's ever...love the work!

[atom]

That ish is hard. I love it.

Whats the reason the manifold is designed like that?

[driftstyre]

Some photos of the steering column. 1.8 turns lock to lock.

[Johny5]

WOW! interesting use of spherical ends on that steering column, very interesting and VERY clever. i like watching the progress of this car, keep it up man!

[RSP13-Sideways]

^^ I was about to say the same thing Johny5....I guess stiffness, vibrations and noise don't matter in Rally huh? hahahaha......GREAT WORK! Still watching this thread like a hawk with updates....

[*NismoS13*]

Wow. Your work still amazes me and I love seeing the updates on your car. Great work so far and keep up the good work! I look forward to watching the completion of this car!

-Adam

[infinitexsound]

is it me or is that a longacre quick release?

[driftstyre]

Thanks for the kind words guys. I'm happy to keep updates coming. I haven't given in to the credit card yet so bear with me. When its motor time I might have to.

The 3/4 rod end on the steering column is very common in many types of motorsports, mainly circle track. This particular rod end is oversized for a 3/4" steering shaft (the ones pictured are from Flaming River). The quick release is from Smiley's Racing, a really cool circle track shop. Don't get me wrong, I can't stand NASCAR but the technology in pro level circle track racing is cost effective and proven. I only wish I had a ford 9" rear end so I could pick one of 300 ring and pinion ratios for $300. Are there any ring and pinion combos that are interchangable with S13 diffs?

[infinitexsound]

if u can find it, try nismo... but most nissan cars run r200 diffs... so parts are pretty much interchangeable....... same thing with the datsun 510 and subaru's both run r160 diffs..

[scir16v]

Ever make another set of those badass rlca's? Or could you tell where to get the balljoint thing that will be used.

[Johny5]

driftstyre, the jdm 180sx's came with a 4.36 r&p (only the ones equipped with ca18det's) and supposedly the extera was equipped with a 4.63 as it uses an r200 differential as well. if you don't want to go through that hastle nismo offers their r&p setups through courtesy nissan at the "glamerous" price of $500ish. good luck!
