should be monday

[meet07]

yeah I saw here sitting up there last tuesday. That se-r at the shop is going to be nasty as well. I noticed that u are going to tilt the turbo flange but what about the wastegate elbow. Are you going to block that off and run some bigger tubing more from the collector?? If so let me know where ur getting that 304sus or 321sus from. will we see you at the track this year???

WTB: RB25 A/C Compressor, KA condenser, KA evaporator, KA or RB Lines, im trying to put together an AC system on my RB25 neo S14!

if anyone has any A/C parts from an RB motor, or S14 KA motor, please let me know

thanksJohn

A question... I have that exact same synapse Waste gate, and i have that same manifold... extensively modified...hehe. But I had to weld a larger flange on it because the seal ring slightly overstepped the flange which would spell leak. Did yours just fit on? oh yeah... I didn't have any boost creep problems on the 30 min warm up and 3-4 good mins. of driving before something went wrong with my wiring.

Awesome man. i think i will weld the manifold side flange on that came with the wastegate to replace the 38mm flange that came on the manifold. I noticed that myself and was planning on looking into that. thanks for the advice! also, which port were you using on the synapse wastegate for your boost settings. i think im going to just not use the AEM tru-boost for now and im going to run a line from the compressor of the turbo to the wastegate using port C (hopefully 10psi) because i still have stock injectors. does anyone think that this will be a problem? (I.E. too much boost for stock injectors to handle?) also im using a Z32 MAF and i will have to set the power FC intake settings accordingly.

[sickness14]

i have the whole ac system out of my r34 rb25 neo clipi have the stock skyline ac compressor/condenser and all the linesi even have the digital climate control n the harness for iteverything is untouched i'll give u everything minus the climate control for 300 if u want the climate control n everything to make it work figure 200 moremy email is [email protected]

VERY INTERESTED!!! this sounds like what i need. now, will the condensor fit on an S chasis behind my radiator? ill have to run it on the inner side between the engine and the radiator because i have my fans between the radi and the intercooler. the digital climate control would probably be a PITA to wire in so ill pass on that. and will the lines hood up to where the lines are on an S chasis firewall? if anyone knows, let me know. DFTSILVIA, ill let you know depending on whether this stuff will work or not.

Thanks a lot man

[sickness14]

ok cool

i also have all the ac stuff off my s14 so if u have to mix and match some s*** let me know

someone sent me a PM on carolina nissans that has " rb A/C Compressor, KA evaporator, and some KA and rb lines all for $100" so i may see whats up with that if i can save a bunch of money. ill still need a condenser, someone local will hook me up with that.

[meet07]

^^^^^^I can hook u up. 50 bucks and you can swoop through tomm to pick up. thats the ac compressor if ya need it.

what kind of compressor is it ? RB or KA?

[sickness14]

UPDATE

-I picked up the head from the machine shop today, looks incredible! Tomei cams are on it.-Manifold is now modified so that turbo does not interfere with the valve cover-Engine bay where intercooler piping passes through has been welded up with sheet metal and piping re-routed-car should be back together this weekend, or monday!

Cant wait.

UPDATE

Bad News...

I just picked up the newly machined head from the machine shop last night with a bill totalling $498. I went to put the head on this morning and realized it is not the correct head. The intake manifold ports are very different and the overall diameter of the ports is a lot narrower than my previous head. I am in an incredible dilemma and am not happy at all.

I was told this was an R34 Neo head. Can the ports be different on a RB25DE from an RB25DET? The intake manifold from the R34 neo will not bolt onto the head.

I will now need another head, then have it machined, and installed.

Damn, dude. That sucks! I wish I could point you in the right direction re: a new NEO head. The only place I can think of is Venus Auto out in CA. They have tons of motors but the NEO is still rare.

Keep going with the project though! It will be worth it in the end!

are u serious?!?!?!...........someone had best get on here and do some explaining....

[meet07]

dude what the h&*@.......this car is nothing but bad luck. I knew a freind that had bad luck like this and he would not listen to me when I told him to get rid of it. He had to total it in order to get rid of it. This build has to be up there near 14k including the price of the car. Sell the motor and all components and do a rb26 swap.

I wouldnt do all that grinding with the turbo inlet open and missing valve cover. Isnt that maf sensor to close to the tb????

Good luck. I will make sure to pray for you tonight.

[USMCgetsome]

im with meet07! sell parts and start fresh and buy from a nico sponsor!

Is it bad to have the MAF that close? I can move it if so. I wasnt sure how it would affect the reading of the maf sensor.

Well, that's a problem too. All the info I could find says this thing was exactly the same as the turbo neo head right down to the springs, and now we can't figure out what the hell it is. The dude that sold it to me said he researched it and found it was the same. What would you be able to sell it as? Best thing I can think of is get $40-$50 for scrap aluminium.

I'm trying to track him down a honest to goodness turbo neo head, but if I can't soon, I'm going to give him his money back.

[USMCgetsome]

no worries cj easy mistake and i'm gald to see your going to man up and help out a fellow niconaut to correct the error

Exactly what i think. He's been a great person to deal with and even though i've been through hell with this, he's been nothing but helpful from day one. I would do business with him again anyday. Good news though,

Ive found an R34 RB25DET Neo head. A gentlemen named chris (ironically) in australia on the skylines australia forums has one for sale, freshly machined, for $1000 USD before shipping. I am considering this option right now as it is my only lead after talking to many other people and running into dead ends as they all wanted to sell me the long block setups for too much money. I think this may just have to be done.

his email to me goes something like this:

"in regards to the head im not sure on a excact price for you as if i sell the head then i doubt i will be able to sell the short block on its own if it i not complete.but the Head is off the block right now, just got it back from my machine shop (which is the same machine shop that do all the warranty work for FORD AUSTRALIA'S 6 cylinder engines) the head is machined and never fitted to engine since machining. if you do want the head i would provide with a brand new Genuine nissan headgasket for the RB25 NEO.

im sorry that i cant get you the head for really cheap but i am allready out of pocket from buying the engine in the first place. im not sure how much it would cost you for shipping to the states but i would be happy to drop the head off wherever the drop off place is in VICTORIA, AUS.

I tell you what, if you can sell your N/A Head you have to get back some of the money you have lost, i would get my head to you for $1000. as i said previous, it is machined and ready to bolt on, will come with %100 new and genuine head gasket, genuine factory (and in-tact) cams and factory NEO cam covers with bolts.

just let me know what you want to do John and again, im sorry i couldnt do you a better price but its not financially viable for me."

Im running on empty by now.-John

by the way, heres some more pics for those of you who need a little motivation like i do.the first three pics are of my friends clean S12 that i rode in to get chinese food today

[Shocker]

Dude, I'd tell him $1000 AU ( I think thats what he means anyways), thats $500 American. That is a TON of money for a head (if 1000 in US), for that price it better come with a set of cams. Not to mention shipping with be a total TON. (It cost me $130 dollars to ship half of my intake plenum 2 years ago there) I wouldn't doubt its $300 + to ship the head.

I know how it is to lose out on a ton of money man. Been there done that, many times. I feel the situation you are in, I've thrown away thousands in efforts to get my car running time after time. (im there again) Every time I got into a s***ty situation I considered the amount of money I'd lose if I quit then. If your serious about making it work, stick with it.

CJ seems like a stand up guy for sure, its tough finding out differences in parts the hard way... I know I have and generally have been left on my own to fix them. Good luck man.

[Darius]

I agree with Shocker. If you search SAU, there are many RB25 heads out there and they go for around $500 AUD. I assume a machined NEO head would go for about $1000 AUD not $1000 USD. That's HIGH!

Shipping will not be $300. Maybe AUD. It cost like $120 USD to ship the 6boost manifold and that's of a similar dimensions.

Its not the dimensions USPS bills on its the weight of the item... UPS bills on both weight and dimensions and will cost more than USPS.

[gawdzilla]

wow that really sucks man. just try to be a bit more careful. we've all bought the wrong parts and thrown away money. lesson learned i guess. take your time and do your research. seems like you are rushing things a bit trying to get parts in and on asap. take time to double check things before spending more money unnecessarily. IMO the $500 machine shop tab could have been avoided if you did a quick visual comparison of the old and new head. extra detailed pics from CJ prior to your purchase could have avoided this mess. you're already doing a great job w/ the pictures on your end. tough break, but CJ seems to be a stand up guy.

good luck though. we'd hate to see a failed project. keep with it

[Cjmartz2k]

I found a turbo NEO motor! I'll email you after I get hom after work about it Joe. I might have to sell some other parts off of it to make it worth it buying the whole motor, so if anybody needs any NEO stuff except for the harness (doesn't have one), let me know.

[neonbomb]

Damn this car has had so many troubles in the past two years.

Neos r ghey!

Good luck with the head problem though. That really does suck. At least it appears you have the funding

[sickness14]

UPDATE

-I dropped off the front bumper and fender at the body shop for painting-Started painting brake calipers black (BS work but i cant do anything until i get the head)-Re-routed some wiring under the hood that was excessive-cleaned and waxed the car lol (wish i could drive it right now) it actually cleans up pretty good-installed some carpet on the passenger side that i had laying around. its not molded though-installed a 4-ch amp i had from my old car (hope it works, i cant test it yet!)-covered hole where antenna used to be (used vinyl and it worked alright for now)-removed spoiler just to see what it would look like. I kinda like the spoiler-less look! others disagree.

and of course... theads suck without pictures!!

If you need something else to do while you wait for the new head check out this thread. It will keep you busy.

I think i've had a dream that went something like that before... LOL That would def. look like something i would do one day if i had a second car. I hate excess wiring. and since i dont have most of the things a normal car would have, theres tons of unplugged connectors everywhere!

I got the bumper and fender from the body shop toady all freshly painted and i must say they look quite amazing

cant wait to put them on the car!

[Cjmartz2k]

Here's the new one, complete with special edition JDM tyte tokyo drift specs super light weight stage 3 V-spec cams! They are so light weight the almost look like paper towels!! It'll get shipped out tomorrow John.

On a side note, I don't think I've ever had a motor fight me more coming apart than this thing. What a pain in the a** motor

[Fibre guy]

Hey, sorry to hear the bad news on the head. But if you haven't welded that WG flange it would be better to seal the bottom one and weld one from the side of the manifold under the turbo flange for more WG control, there is way more than enough room in an s14. Mine is temporary, only until I finish the exterior of the car, so i wasn't to worried about boost control.Also the synapse WG has different boost settings by switching around hoses so you can run different levels of boost without a boost controller, just run 4-5 in. of vac hose off of the open ones and point them down so debris doesn't get in.I ran an independent vac hose all the way to manifold for the WG.
