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

[meet07]

What about NisTune or Haltech? (I really don't know, just throwing out options)I was checking out the Haltech at SEMA at the begining of the month, their Platinum EMS is pretty nice, got to play with one for an R33 RB25 that they actually had there !

Hey John when I dynoed my car down at Majestic Motorsports in jacksonville. Nc they quoted me somewhere around 1500-2000 grand to install,wire up and dyno tune the Haltec system....Not to sure about it but they know there stuff over there. There running a fast as supra with all the goodies.....check them out or call. Forgot the owners name but really great guys....

[Cjmartz2k]

Meet, first off, Haltec kicks a** from what I've head, it's just expensive and it's a little hard to find people to tune it. That's all I know about it.

About water/meth injection, you actually wind up taking OUT a lot of the fuel so you could run smaller injectors if you want. The meth acts like very high octane fuel, and you no longer need the extra fuel to cool the combustion chamber since the water is doing it. I've heard people pull the equivelent of one who AFR point of fuel out of it when the water/meth spray. Now Nitrous is a whole different animal. You do for sure need more fuel for thtat. It all depends on how big of a hit you spray.

O yeah, I already mentioned to John I'd want to come along the the place down in Concord too, especially since I'm almost on the way. Maybe we could all make a day/weekend out of it down there

What do you mean by re-flowed. do they basically drill out the smaller injectors!? wtf. thats ghey. ugh.

Carl may be better at explaining this than I, but you have the idea.Take common KA24 injectors, cut part of the tip off and test flow.

Spend the coin on some different (not hacked stock) injectors. What type of injectors does the Neo use?

Same as R33 RB25 (Side-Feed, Low-Impedance)? If so, look into STi 'yellow' (0d20) around 04-05 I think) injectors, they are drop-in replacements. Just make sure you get the correct number and cc/min, of course.

As far as Haltech is concerned, you can freely download their tuning software from their site and test it all out, before buying an EMS from them. If I remember correctly, I could get them for ~$1400 also.

It's awesome you guys live near each other. The closest people to me are Evan (240z4u) and Steve (stevespeed) and they are both ~5 hrs away. Well, except for LargeKid and Mott who are about an hour.

[l0nestar]

I just had a dumb question.. Did we ever find anything out about the S-Tec manifolds and fitment in LHD cars?

Something piqued my interested about them this morning.

[Cjmartz2k]

Pretty damn sure the wastegate piping fowls on the steering "thingy" (column?) coming out of the firewall.

O yeah, and Neo's do use a different injector stock, but I think John's running a greddy intake with a different then stock fuel rail.

[l0nestar]

Yeah, I just saw your S-Tec review like.. 2 posts down.

Steering shaft. Then I has no idea what to do about injectors.

Dear sweet baby jesus.

NICE!!! thats on big as.s turbo....

Props on getting your dogs to sit still!

[Cjmartz2k]

LOL, told ya they aren't tiny turbo's

[l0nestar]

Holy Huge Pictures Batman!

Looks good man! Can't wait to see that bish bolted up! :

[meet07]

Hey John how about you bring that manifold and turbo over to my house...we can bolt it up to motor and see what kind of clerance issues we find...like the valve cover and the steering shaft.

[sickness14]

Which mount kit are you using, and do you have the R33 crossmember? I know the wastegate dump will def hit the steering shaft but im not using it like that anyways. ive got to get some more 321 stainless and re-do the wastegate runners to the 40mm flanges.

The downpipe is also going to be fun, i sold the one i was using previously for $150 plus shipping. ive got to mail it out monday. Ill need to have another one made, with a 3" v-band. The holset turbo v-band is very broad compared to a standard one so ill have to find out how i can make that work. and the discharge will be v-band as well, 2.5" to the intercooler piping.

[meet07]

nah im using the ruckus racing mounts....you got me thinking about getting rid of my hx35 and going the hx40 route but kinda worried b/c the ones on ebay, there saying are capable of 800+ hp

thats alot!!!

[Cjmartz2k]

That's just BS, and I'll bet it's the china copies you are looking at if they are advertising a hp level with it. The DSM guys have dyno sheets saying like 650awhp at 45+psi on a super low compression motor with race gas and that was on a super friendly dynojet. I think the most you would see at reasonable boost levels (under 2.0bar) on an RB25/26 would be something like 550rwhp or so. That's just a guess, but I can say for sure you aren't going to see no 800hp with an HX40. You could probably see that with an HX52 though at the motor.

I like the idea of trying to fit the manifold though just to get some pics and an idea of how bad/close it fowls on the steering shaft. I'm sure it will though, just how bad is the question. How close are you guys?

[meet07]

i was thinking the same thing about the numbers after looking on youtube at all the dsm guys running that hx40. Most seem like they where seeing full boost by like 4-5 grand....

But yeah its up to john to swing over to my crib to mock it up...ill probably be replacing my turbo/manifold this winter anyways..

holla at your Boy Mr. John

[Cjmartz2k]

That's 4 or 5 grand on a 2.0L DSM keep in mind, not a 2.5L RB.

[l0nestar]

HX35 needing a home, you say?

:-D

[sickness14]

Id rather just wait until i get my car done and set it all up at one time. since you're using a different mount kit, and the US crossmember, it wont provide any more accurate measurements than what i can estimate in my head. thanks though. I don't want to bolt the turbo to the manifold until i clean up the inside of it and remove all the metal debris. don't want that going anywhere near the turbo.

so order of events are:

-waiting on friend to take the head to RLZ when he makes a trip down there hopefully within a week.

-after the head is done --> measure for ordering correct head gasket, a tomei 87mm one. I'll also order: Balancer, slave cyl, mini twin disc spec clutch.

-assemble long block, and using new head gasket, and engine gasket kit, re assemble the motor. I'll have the valve covers, the alternator bracket and ps brackets as well as alternator pulley and power steering pulleys powdercoated black. may polish the alternator.

-assemble timing components, and put the oil and water pumps back on, using the new harmonic balancer.

-instal new mini twin disc SPEC clutch, and new oem slave cylinder, while putting the transmission back on.

-next step is to do the cold side intercooler piping re-route. previous shop welded up the hole where the battery tray use to be, so i want to make a nice 3-3/4" hole right where the 3" piping would come up into the throttle body.

-grind down the inside of the mani, put manifold on the head with the turbo bolted up, without modifying any wastegate piping just yet. then see where i have room to place the wastegates, check clearances for turbo / valve cover / strut tower. using 321 stainless, extend and rotate wastegate primary's with 40mm piping to the two 40mm synapse flanges and the wastegates will be done. then make two dump tubes to carry the air far enough away from any vulnerable parts.

-next step = the downpipe. going to be fun, the task is to make a new 3" down pipe using the 3" v-band flange. the downpipe will hopefully be one piece from the turbo to the resonator, including an o2 bung. and a couple of exhaust hangers.

-then getting the correct fittings for the -4an oil feed line. looks like the 1/8th npt is too small to thread into the holset hx40 oil feed. the oil return flange should be the same on a t3/t4 hopefully.

-after the main components are all bolted up, with all gaskets, torqued to spec. then the new isis coolant lines will be installed, as well as the rest of the coolant hoses, and then finally the wiring harness will all be connected and tucked under the intake manifold.

-after some time has passed and i can put enough money aside, i will order: 800cc injectors, greddy fuel rail, bosch 044 from ricky. then pick up -8 an and -6 an fuel feed and return line in the push-loc type of hose from Parker hose & fitting supply near my house. ill then get all the correct aluminum AN fittings and continue to assemble my fuel system.

TO BE CONTINUED.

[Cjmartz2k]

It's coming along man! You are really going all out with a lot of the stuff you are putting on there too. One suggestion, for the level of hp you are going to make, could you do anything bigger than a 3" exhaust? I'll plan for 4" when I do mine, and least to a electronic dump of something like that, the maybe 3" after the dump if I can't find a 4" exhaust.

[sickness14]

Chris, it really is going to depend on steering shaft to block clearance as far as running 4" pipe. Id love to

[l0nestar]

Coming along well. So you decided to go with the SPEC mini-twin?

[Cjmartz2k]

Gotcha. Guess you'll have to wait to mock it all up.

[sickness14]

I guess so. Waiting to hear back from them to see if its a pull type setup

[sickness14]

Found some interesting stuff

if i were to go with 4" downpipe...

http://www.034motorsport.com/p...19131

And also, found 2.5" aluminum v-band, and a 90 degree 2.5" aluminum bend.

hey guys, ive been busy lately working on the Kognition Design carbon fiber sunroof delete. finally got it installed. Enjoy

[meet07]

I guess so. Waiting to hear back from them to see if its a pull type setup

Im calling them today. my sunroof has been leaking for over 2 years now and I cant find a seal to save my life.....!!

Thanks

[Cjmartz2k]

Hey man, I got your message. Sorry I haven't called back yet. I'm freaking s*** kicking busy. I just moved into my apartment and I'm going up to D.C. to pick up Kazuko (JDM GF) tomorrow. I'll be laying low for the next week or so, but I'll get up with you maybe this weekend man.

Did you ever get a hold of the machine shop down in Charlotte?

[sickness14]

Block painted, deck surface micro polished. crank is in, but waiting on one of the main bolt nuts to come in from ARP that was misplaced.

[Coolwhip]

sick!
