Hi all,

OK long story short I have 2 cars, 180sx (daily) and r33gtst S2 1998 (102,000km) <-- weekender/race/show car (bought as a repairable writeoff, all repaired and on road for 11K)

OK so here the idea, will have:

HKS KAI T51R KAI BB

Plans in future to run e85

rb30/25

black car, black rims, 20% tint, sleath/sleeper engine bay aka black lines etc,.

Now the list of questions/recommendations?

Starting at the bottom, who makes a reliable rb30 bottom end (rb20/25), R.I.P.S, Lewis, ProEngines? maybe I should reading zoom and hot imports more often :rolleyes:

Injectors 1000cc minium, indy, sard, bosch, denso? need any bigger to run e85 saftey in the future?

intake, plazaman look good, are 90mm+ TB really needed?

6boost turbo manifold? who else makes good turbo manifolds to suit 25/30.

Really the question is are their any shops here in QLD (preferable Nrth QLD) who would put togeather a build like this if I get a bottom end from one of the above? mackay, townsville, cairns? all about the same distance from where I'm based at.

Bottom ends, all those you listed are reputable.

Injectors, probably want to go for the Bosch 1600cc (Indy Blues?) so you have enough headroom for E85.

Intake, probably best to go with GReddy as the Plasmaman unit, while nice, bolts to the top of the stock runners which may causes clashing issues (stock plenum on my 30 in my 32gtst, I couldn't fit the strut brace back on).

Exhaust manifold, I have a 6boost made for my application, nice bit of gear. There are a couple of other good local manufacturers out there but can't remember their names (XTM? etc)

Few thinks to note:

- HKS KAI T51R KAI BB, aftermarket plenum and 1600cc injectors can NO WAY be made stealth :no:

- 90mm TB is definitely required for the turbo used.

- Cams, an aftermarket ignition system and possibly a port job would be highly recommended

I use a ETM manifold and have found it to be a very good unit. Just don't purchase their aftermarket sump set-up (bad experience)

Good luck, hope you have lots of $'s; as this is not a cheap exercise!

Yeh well I'm looking at doing all this under 20k mind you... I think I can manage it without to many issues, yeh not "sheath cops won't know shit" just black is nicer.

Turbo is 4k, 8-9k for the engine/porting etc, the rest will be intake/turbo manifold (2.5k) injectors, fuel setup, braided lines, etc. Black braided lines easy to come by yet here in Oz?

8-9k wont get you an engine built to take a T51

so I need to save up more huh :ph34r: how much more?

I can understand alot of places are edgy about giving out quote over emails, but I do kinda need a number to work around.

think more along the lines of 17-20. a 400-500kw engine isnt cheap.

Hmm really, I didn't not think it was that much, granted I based my prices on lewis engine site of 10k for a "unbreakable" RB race engine, well, 400kw is pleanty in any case I would think.

Well, I'm here to research, gonna be towards the end of the year if/when I go ahead anyways. Just need to sort out decent intercooler, radiator, all the aux stuff.

Gday mate, im also heading down the same path as you, but ive got a GTR 30/26. I got my block made at Spool Imports who im fairly sure are located in QLD.

As people have said, 8-9k for engine / head work no where near enough for the amount of power you want. Ive spent roughly about 15k and my head isnt bolted to block yet. It probablly can be done within 15k for block done, head ported, new valves, springs, cams etc etc.

Awesome! so not gonna be going this year then :closedeyes: ah well, rather do it once and do it properly. Suppose I better go annoy all the other fourms for recommendations on clutches, ecu, intercooler cores etc.

Also I'm not chasing a set power figure, actully my only goals are the HKS T51R (OK so I'm one of those guys who just *adores* that sound) and the fact I want to be able to get it over 300km+ (s15 diff (3.7 ratio) will help, also why I need the rb30 bottom end = torque)

@MattsR33

Yeh but GTR engines also cost a bit more I assume as to the 4wd box would make it more interesting/costly?

For a engine combo you are 'thinking' of putting together. You can throw a budget out of the window.

Just the supporting mods alone for a T51R will be close to 20k.

For example the fuel system will be 5k easy.

My advice would be to do alot of reading and see what other people have done and go from there.

20k is fine, and I have read up a fair bit, but finding people with T51R setup's aren't all that common, seems the T04Z are the flavor. There are a few knocking around around but details the actual setups are a bit sketchy. heck I've seen people running 400kw+ on stock bottom ended engines :wacko:

GTR would cost abit more to put a 30/26 depending how far you go, but its still using the same block / head setup you would need to build. I havent even bought / built the sump - front diff yet.

It all adds up very quickly as people have said!

Lots of comments in here that are misleading but some that are spot on.

First off, this will cost mega dollars.

Forget a budget of 20k. If you are set on a T51R SPL,, you'll need a gearbox worth over $10000 alone regardless of the top speed you want to reach.

Building the motor is only one part.

nah KAI, SPL are 1000ps... Plus I'll probably get a PPG gearset later on anyways...

yesh I'm one of those people who A. loves HKS things and B. the intake noise from a KAI.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
