The first and singlemost thing I can recommend.

STOP PICKING RANDOM PARTS FROM MID AIR.

do a search, keep searching and keep reading.

have a look at the rb25 turbo upgrade thread.

read what others have done.

search for things like:

Grepins is the HKS GT2835ProS, plenum, exh. manifold, cams and a few others bits and pieces. He's really pushed the 2835proS to its limit.

Freebaggin ran a GT3040 with a .63 5bolt style turbine housing and stock style comp cover. Tim Possingham did the specs on the turbo for him some time ago. Back then it was worth close to 3k. The housings weren't simply machined to suit they had more work done to them. I believe it origionally was making 280rwkw on 17psi. Changed comp cover to the .7 ramped boost up and made over 300rwkw. Maybe he can share a little more insight in to what exactly was done to get the power.

-i have most likly forgotten something but this is a good start

hks gt2835 pros is good turbo but if u want 300kw, u need a bigger one

Hello everyone.....

I was flicking through a "high performance imports magazine" and I saw an ad for a high performance engine rebuild kit for a RB25-DET. It consists of:

  • Venolia forged pistons
  • Grant chrome rings
  • R.E.V. I-Beam forged conrods
  • Tomei metal head gasket
  • Genuine Nissan full engine gasket kit

All of this is for $3999

Is all of this stuff at a good price or not???????

cheers :happy:

Dont get Venolia... Get CP or ACL pistons.

Is that's the kit from hi-octane?

Have a look in the RB25DET turbo upgrade thead for turbo selection for a few ideas 2530 is to small for what you want to do.

Id recomend a HKS GTPROS turbo kit comes with everything needed and bolts onto the stock manifold, it will be good for arround 270rwkw with room for a little more.

At levels above 270rwkw you may run into reliability problems if you drive the car hard, plus the you will need a large turbo whcih means more lag.

For 300rwkw+ a rebuilt engine with a 3 litre bottom end would be a good option the extra capacity will give you less lag and power can be made lower in the rev range which means less stress on valve train parts.

If you go the HKS PRO-S route you will need the parts others have already stated

Injectors

- S15 JDM manual type, nismo 550cc or 740cc

Fuel Pump

- new bosche pump 040 or 044, tomei or nismo direct fit

Air Flow meter

- Z32 airflow meter will be plenty big enough

ECU

- Power FC with Hand Controller and boost controller option

Clutch

-Exeedy seem to be a popular choice

Cams optional but recomended

-Tomei pon cams

Intercooler

- might want to go for a JDM type, not sure how the cheap hybrid and hybrid copy coolers will go at this power level.

Exhaust

- 3 to 3.5 inch exhaust from turbo back with highflow cat (the bigger the better)

As for pricing it can vary shop around www.nengun.com has good prices for your cams, turbos, ECU and intercoolers.

Search the for sale section on this forum heaps of specail offers for exhausts, intercoolers, etc.

If you shop arround you may be able to get away with spending less than $10,000

cheers

Better yet, you can even see the video and look at the nice telly screen of it. :O

How good is that eh? Stuff having a sheet, live video recording is a joy.

http://skylinesaustralia.vidiac.com/recent...a697e4dad6e.htm

That also includes a backup run of 358rwkw with a bit less timing.

Safe to say there is nothing wrong with an AFM based car at all.

OMG...thats an awesome vid nismoid..

I assume thats your car ???

Can you PM me some details on the setup ?

Looks to be a lowmount with an external gate ?

hehe those manifolds look suspiciously like GTS-R ones :D

Suspicion would proove correct :O

I actually own a GTS-R... and it still retained some of the Nismo gear from the factory, the GTS-R manifolds are awesome.

Good mate of mine now owns the manifold, they are worth a pretty penny lemme tell you.

PM sent :D

Amazing how the peanut gallery went quiet once the video came out hehehe.

My tuner has expirience with both MAF and MAP applications for the RB's.

If he tells me in his expertise that the AFM is not a restriction, then i'll believe him based on his testing and applications.

I trusted his judgement and made more power than anyone else said was possible at the time.

When a PowerFC is $900, and the AFM $250-$300 thats $1200.

Would i be right in saying a MAP based ECU is a little more expensive in most cases?

The closest that comes to mind is $1400 at the very least. I think more decent are wire-in at a $2000+ cost

So cost for cost, the AFM + PowerFC Combo will works out cheaper.

As stated he is in Vic, and *most* tuners will prefer to use a PowerFC down here as opposed to anything else.

Nar MAP based ECU isn't always more expensive.

Some people are happy enough with a MAP based tune also, even if technically its not as responsive.

$1000 for Microtech (with x4 ign module) on my SR20 - $300 for tune. Self installed. total cost $1300.

$1200 for PowerFC + the tuner said he would charge a tad more for PowerFC tune. Total would have been $1600.

I'll probably go PowerFC on my skyline though, two more injectors and two more coils to wire might scare me off the microtech install again. Takes take a few hours to wire an ecu in.

Suspicion would proove correct :ninja:

Quiet??? did somebody say quiet? haha

IMO

seen better...

spoke too soon nismoid...

oh yeh by the way...i think the reason i went quiet after u brought that video out was cos YOU BARRED ME cos ya couldn't hack it and ya had a cry...bit hard to speak up when ur barred ey!

My 2 cents

lmao... yer right..

And were all going to believe that. lmao.

:O

Hey you know whats funny...besides ur name...if you mix the letters of 'lmao' you get LAMO!!!! something for you to think about :D

I believe Nismoid ran the stock gtr bov's.

A GTR BOV >_<

Just one... not the both of them, you can see it in the vid... it is even plumb-back :sorcerer:

Was actually talking about it today, it worked so well with just the one even with that amount of boost given.

Definately worked beyond expectation without using both of the BOVs like on a GTR.

There was a tad of flutter on 24psi.

However when using under 20psi it was actually quite ok and there wasnt a hint of flutter or anything so yeah. Worked well IMO.

  • 1 year later...
as i posted in the other thread

stock gtst

+ front mount $800

+ exhaust $1400

+ ecu $900

+ heavy duty clutch $1200

+ hiflow turbo or gt-rs or gt2835 ($1900 to $2800)

+ airflow meter z32 $300

+ fuel pump $300

+ injectors $600

+ cold air intake $300

+ boost control kit for ecu $300

+ tune $500

+ suspension work $1200

total $10,300

should net you somewhere from 250rwkw to 280rwkw

ive got most of this to go on my car except for

+ boost control kit for ecu $300

+ injectors $600

so at the moment ive got 182 or 84 rwkw now on low boost 5psi splitfires made me gain a few kw too

clutch no need ive got a auto but have stage2 shift kit but have to change to a manual-auto because ove shift point issues with aftermarket computer should i see around the same figure ps im in the process off getting nismo 555cc injectors for it is that ok?

    • @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.
    • Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
    • 9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.
    • post up screen shots of your injector tables
    • Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same.
