Fix Thread turned into Re-build thread! (built rb25 neo)

[l0nestar]

This is what I like to see!

[sickness14]

thanks guys!

I finally decided what im going to do for a clutch setup.

Exedy Twin Plate Clutch Kit – NM042SD ~$1700. AND ITS PULL TYPE!!!! YES. supposed to be rated for 500 ft lbs at crank. should be plenty. there isnt much lacking in my setup for power goals of ~500 wheel i dont believe. correct me if im wrong. I want this to be a FAST street drivable car that i can take to the track. i hear anything over 600 is where you start breaking s***. i think then i would need a better oil pump. (tomei).

Another thing... do you guys think i'll be alright leaving the cylinder head internals mostly stock besides cams? will this cause any reliability issues with spring pressures, floating valves, ect. i need to figure out whether i want to build the head now before it goes to RLZ for the quench pad repair because they're going to have to tear it down. is it worth going with like a supertech valve spring & retainer kit for ~$400, or a tomei type-A or type-B valve spring kit with separately purchased retainers?

just need to save up some more $$$$ to get it. and then purchase the new fuel system. still trying to decide whether to run twin walbro's or a single bosch 044. twin walbro's would flow more.. but people question their reliability.

this is the remaining parts list from raw brokerage. its going to be tough from here on out because im starting school again in January.

Personally, for that kind of coin, I would go with an STR2CD from O.S. Giken (R34 - RB25 STR2CD) and it retains the pull-style.http://www.osgiken.net/products/strclutch.html

But that's me. Everything else looks good.

Where did you find pricing on that setup? Im coming up with :

BNR34 STR2C $2759 (includes pull-push converter kit).

http://www.otomoto.com.au/osgi...e.htm

Is it not a pull type? thats $1000 more than the Exedy! lol

My pricing was direct from O.S. Giken when I was at SEMA last month. I will email you my contacts email. I actually need to email him as well for something else.

Use the link I sent you. You pulled up the street two-disc for the bnR34 (GTR) not GTS-T. (or does the Neo use the R chassis code? I thought that was 26 only)

I was looking at around half that for my R33, but that's also a push style.

Hmm. SPEC does not appear to make a multi-disc clutch for the 26 either..

[sickness14]

The neo uses the same clutch as the GTR.

[l0nestar]

The neo uses the same clutch as the GTR.

Hmm. I knew they were similar. I emailed my contact at Giken. Interesting that they list a different part for the R34 RB25 & 26. (both are STR2CD style, but the 25 is about a kilo lighter) I also asked if you would require a push-to-pull conversion.

I'll let you know what I find out!

I called OS Giken in cali, talked to sean and he was a cool dude! He suggested the TS1, which is a track inspired street clutch kit that uses a stamped clutch cover, vs billet aluminum. the pricing is around $1700 for that kit. it has a slightly stiffer than stock pedal feel, and will hold 600 hp. Its a twin disc, and needs the push to pull conversion which is $450. Its better than the OEM pieced together conversion, this one is billet and will retain the strength of the pull type trans.

sean recommended that i should contact a place in FL called Billet design and speak with Marco. he has experience with RB setups.

Hope this helps everyone in the future. Looks like i'll be getting this setup.

Im running the Exeddy Twin Disc pull style in my NEO, and I have to say that clutch is an awesome addition..I have not had one single issue wth mine in the three years its been in there and its seen close to 550whp so I am pretty sure you will be good there. Just be mindful of the somewhat fragile third gear in the RB trannies..I had to learn the hard way..now im running a Z32 hybrid in my setup still using the pull style RB front bellhousing. Here is the link in case you are curious about it.

thanks man! im debating between the two. the OS needs the push to pull conversion kit, its going to be like 2100 total for that damn thing. hmm. isnt the exedy like 1700?

update:

later

[S14-NEO]

yeah the Exeddy is a better price, just remember that there is a REASON why the clutch is a "PULL" style on the NEO and well as the GTR...IT WORKS BETTER along with a better feel

John got my downpipe a week ago or so...just wanted to say thanks and let you know it arrived fine.

Thanks again.

[noodl35]

Is that the best they can do? That looks a bit shotty to me. I personally would not put that on.

[mott6904]

Wow... if that was my head and i got it back like that i would demand my money back. I would deff. have it welded it up. I looks like some redneck did it in his backyard. Thats no good

[boosted98gst]

No offense but that looks like complete s***! Anyone that owns a shop that puts out work with there name on it like that will not be around long.

[S14-NEO]

just remember if there is any sharp edges in the combustion chamber at all, it severely increases detonation...(NOT GOOD)...besides it looks like total a**.

[sickness14]

The head is now at a machine shop being welded and getting a valve job & surfacing. They'll also set my clearances and CC it so we can get the properly sized head gasket from cosworth or tomei.

[flatrate]

it needs to be welded back up and machined via CNC not dremel

[noodl35]

if it turns out to be alot of $$$ welding it, just find another head.

[S14-NEO]

no matter how you slice it, the head is either going to have to be repaired properly and or replaced. With the amount of money already invested in it, wouldnt it be a shame if somethign terrible happend like detonation. from what i can see on the pics you sent me there would no freakin way i would throw that head on my NEW engine SETUP and be ok with it..NO WAY!!!

[mott6904]

I work at a motorcycle shop that specializes in building engines and porting heads. A turbo 1000 came in about 3 months ago that did the same thing and we fixed it like new, you couldnt even tell if was f***ed up. Let me ask the boss man about fixing this for you. The only thing is you need to ship it to indiana. The only issue i see is that the damage is so close the valve seat. It can be fixed but it could be expensive.

[sickness14]

Short block assembled, head is at the machine shop being welded. head will also be tapped for oil return drain

Now we're trying to figure out what thickness tomei 88mm head gasket to get. I cant seem to find an answer on how to measure the block & head to determine the compression ratio correctly.

Did you get my link?

[sickness14]

Yea, I joined zeroyon and saw that thread. It doesn't say much so ill have to pm scott

Did you get my link?

I was contemplating going with an all out nasty fuel system, and dealing with the Z32 maf maxing out issue right off the bat, but i think ill just get the car running with a single walbro and a Z32 maf and see what power i can make .

after some time, ill upgrade the stuff some more, either with a Ford lightning maf using darius's specs for the pfc settings, or twin Z32 mafs.

It looks like i'll end up going with the Selin dual maf translator, twin Z32 mafs, and a Greddy y-pipe if i can find one. which is REALLY hard to do right now, i cant find anyone that has them.

heres the selin maf translator

http://www.selindesign.net/electronics.html

Then for the fuel, ill probably run twin walbro's in tank with all proper lines. what power will a nismo FPR, stock rail , stock lines support? 480ish whp sound ok?

also found this website, pretty neat concept.
