That is a totally wrong, and inaccurate statement.

What is full boost?

You want 'full boost' go to the web-site... www.fullboost.com

Maybe asking, at what RPM do you achive 12/15psi would be a better question.

I would appear stimps you are either very confused or full of shit.

Either way I think it is a good idea to get stuff right before you start to post up making claims.

There is enough dis-information around already, adding to it doesnt help.

A warning to others that may listen too long or hard to your comments.

:werd:

Couldn't have said it better myself.

I also agree with SydneyKid.

It was only a matter of time before the JMS 33 came into troubled waters.

About 250rwkw is all i'll be chasing on stock internals on pump fuel and as lower boost as possilbe, anymore and i'll be playing with danger.

Is this possible? Is it sensible doing so?

If so, what are the cost involved and also performance wise? Can this car keep up with the GTR?:burnout:

As for beating a GTR, lol, good luck mate.

Even if you waste the money on going RB25DETT... you aint never gonna account for the 4wd.

A GTR is in a different class to a GTS-t

You want some good advice, get rid of the TT idea as it's not sensible, and go get a decent single turbo.

Maybe then you might just keep up with a GTR, certainly not beat one.

I dunno about that, I've read of plenty of GTR owners getting beaten by cheaper cars like GTS-t's. The reason? Their car is stock. Why is it stock? Maybe they forked out too much on the initial outlay on their car and they couldn't afford to mod it.

Yes a wildly modded GTR is probably going to beat a wildly modded GTS-t at anything (except maybe drag strip where weight is more important). But if it was a choice between a stock R33 GTR and a GTS-t with around $15k+ worth of mods (both working to be around the same price) then give me the latter anyday.

I'm a poor bastard! I can't even afford the $15k of mods, let alone the stock GTR.

A mild modded GTR flogs me stupid off the line.

It's all about traction.

Exhaust, boost, clutch and ECU, (maybe a better cooler) and your GTR is fishing around a high11/low12 on street tyres. Tell me a GTS-t can get there that easily and i'll know what im doing wrong.

If we are going down the modded cars vs. stock car argument then that's not entirely fair.

And are we talking a drag, track or street?

In all 3 classes a stock GTR vs a mild modded GTS-t... i'll let people decide who'll come off the better.

I already know.

I'm only speaking with respect to what a car owner can afford. If I had $40k, do I buy a stock R33 GTR or a wild R33 GTS-t? Decisions decisions.

hehe..well this has jumped straight off the ship and back into GTR vs GTS-T ..

There isn't even any particular reason for running two turbos.. People tend to assume "oh its got two turbos it must be better" when sure, under "out of factory" specs they are, but that is the way it was intended... however for most purposes a single turbo is easier to maintain, balance and above all cheaper mated to an engine - otherwise a lot more cars would be using a twin turb setup from the factory. A lot of the top drag cars also switch back to a single turbo for many reasons, many of them similar.

If you want a really quick car, just sticking another turbo on it is really a very inefficient process unless the engine is built for it. If you want the power, go the proven combination of a fully built RB30, ported RB25 head, and big turbo. I'd rather have that combination for $x than any RB26DETT you could care to give me.

Take the VL boys - while they're brutish and simple, there is no reason a well matched RB30 and single turbo combination can't do 9's WITHOUT spending a fortune. Its about time more GTS-T cracked that territory, there isn't any real reason why they can't.

Also, its not all about the line. Unless you are drag racing, the takeoff ability becomes less important. Sure its also about cornering, but a GTS-T correctly setup is also damn good for a RWD.

I can think of many good reasons, most of them dollars.

so how much do you thing TRY09 cost? Farken heaps. And I dont think its that cheap on a VL either, still 10s of thousands.

then when the dust has settled, you dont have a very streetable car - or at least what I would call streetable.

If you go twin turbo on a GTST, you have added expense of paying for two of everything, it all adds up.

Much cheaper to go a big single, doesnt have to be a lag monster to give you enough power to get into the 11s, and an low 12 or high 11 sec car is very quick for the street.

Still going to cost 10s of thousands, either starting with a GTR or with GTS.

Rant rant *$*#ing rant......

I never set out to beat a GTR, even tho my car is already quicker than a stock GTR, but lets face, stock is STOCK...and bloody slow.

Yes I made those twin manifolds myself, and the whole reason why i biult this car, is to make a street sleeper....CHEAP.

I had a spare T28 sitting around (cheap)

Had some tools and time and access to a quality TIG machine.

Cost of engine...around 3k.

other bits, intake manifold, 600ish...

Extra injectors.....free (old stock VL ones from wrecker mate)

Extra fuel rail...free, (home made)

New polished fuel surge tank... free (home made)

Extra fuel pump..free (again wrecker mate)

polishing...my time...free (but dont ask for it:P)

Twin 2 inch 90 deg dump pipes made out of shed 10 steel pipe and welded into one 3 inch exhaust pipe..back into existing 3 inch system... $40 for the steel

Stainless bends and pipe for the manifolds, $90 from midway metals gold coast

E6k $1800 from a pre existing biuldup

thats about it.....oh and a new carbotics race clutch.

Car goes unreal, gets boost (considerable boost 12 to 15psi) at prob a bit over 3500 (that will be better when the wastegates are better fitted and set up properly, getting some wastegate creep me thinks.) And ive allow it to run 19psi lately. Seems to just love it, no signs of any problems as yet. Only problem im having is the boost climbs slowly from 15psi at 4000rpm or so to its peak of 19psi at 7500rpm (redline 7800) which is more of a gate setup problem than anything else. I set the E boost to 16 and it just runs 13. Quite frustrating but im working on it.

I shit you not it would easily rip off a 12 something the way it sits, but of course im doing heaps more refineing and tuning and sorting out before i go near the track.

and sorry for the inacurate information before...can we drop it now PLEASE. Get some maturity those of you who just turn into keyboard warriors and rant off at someone elses mistakes. Its life.

Hey gordo...

Just how much do you think the VL's cost to get inot the 9 sec bracket?

I think you'll find with all the years, research and development most of those cars have been through... that it's not as cheap (or as easy) as one thinks.

The motors alone have over 10g's on them

But back too the TT thing, as Steve said, one single will be just as good as two smaller ones, if not better.

And before you max out your bigger turbo, you'll probably need to spend some reasonable $$$ on the motor.

i wasn't implying they're were dirt cheap or easy to get to that state.. but *relatively* speaking, compared to some GTR's and things, they've had a lot less spent to get into a comfortable 9 or 10 sec bracket. To me $50k is "cheap" compared to what it costs to get a GTR to that level.

I was mainly trying to make the point, that twin turbo and 4WD aren't mandatory to have a very fast skyline.

that is quite true.

But when you get to the 10-9 sec bracket, a RWD car is usually cheaper to make go faster as a rule.

but for the sake of this argument i dont think it's going that far :P

Hi Stimps, what sort of work do you do? As in what is your hourly rate? Because if you had spent all the time working (O/T or otherwise) that you spent on the car, how much money would you have made?

That is then the true cost of the mods. You didn't get them for nothing, it cost you time and time is money.

I have no idea what you do or how much you get paid, but I will bet it would have been much "cheaper" to have bought a good second hand, complete, single turbo turbo set up than the money you lost by not working at your job.

How close am I?

PS; Yeh, I know about self satisfaction, doing it yourself etc but that is not the point of this thread.

If you'd taken the trouble to read all the posts you'd see that Stimpy says he's running 10psi in the post before mine.....sounds like thats full boost ;)

10psi isnt full boost its sorta unknown yet as Im still tuning and setting up this motor (never seem to get time to do much with a house and going away all the friggin time.....)

Sydneykid.....

holey shit man you just blew me out of the water with that comment...the time spent? ermmmm..well im an industrial electrician and i get around 20 bux an hour....and i put in around a years work of my free time (and some of my works time too hehehe) and yeah if you put a figure on it...yeah id say about a years wages.......SHIIIIT.

I simply went the twin turbo way because it meant bigger turbo power for basically bugger all money. Had a spare turbo, did some welding..wallah.

Took me around 3 weeks to construct the exhuast manifolds the turbos sit on...had to reweld them 3 times to get the turbos to sit just right (and fit in the engine bay) and another two weeks to get the dump pipes finished.

Took weeks to do all the polishing and about a month of playing around to get the extra six injectors in there right.

Have frigged around with the intake manifold and plenum so much, put it on and taken it off like a dozen times to get that right.

Yeah, when you look at it like that....its expensive. But its the way I like to do things. I just cant justify handing over great wads of cash to someone else when I can take my time and do it all myself. Its also neat to say "i did" when someone asks who biult it all.

Ive welded all the stainless tank shape things (surge tank, radaitor top resivior tank, steering resivoir tank ) and now i get all my freinds asking me to make stuff for them. And not to mention all the hours I put into welding up the cooler piping, and intake air pipes to the air filters. Home made alloy BOV at the bottm left of that piccy too I made around 2 years ago.

there's a certain satisfaction you get when you build it for yourself. It becomes your own piece of art, that you spent time swearing, bleeding and labouring over. In the end you have a creation that you can say was proudly built by you! I'd love to have the metal working skills (and associated hardware) to construct and fit some of the more advanced parts like you've done stimps, my hat is off to ya.

Another advantage of doing work yourself is you avoid a lot of tax :rolleyes: Also you will never get a phone call saying "I'm sorry but we've found a problem with this mod and we're going to have to double our labour charge and you need an extra $500 worth of parts". Sure you might find this yourself if you do the work, but then you can put it back the way it was if you can't afford the extra parts.

Whenever I work on my car I weigh up the hassles with the costs. That's why even though I was more than capable of changing the gearbox, diff, and clutch fluids myself, I just took it to Midas and paid them $30 so THEY would be covered in all the crap instead of me. I don't even have any overalls! I supplied them my own fluids to not get ripped off in that department, and watched as they did it to make sure that my own fluids went in. Best $30 I ever spent on my car :)

I also wanted a workshop to do my fuel pump for the same reason, but the workshop I went to was a bit grumbly about it and it didn't instill me with confidence. After hearing about some horror stories of bad Bosch pump installs, I was glad that I did it myself in the end even though it took me about 3 times as long as the workshop would have taken.

yeah, if you just go about it sensibly, research a bit to make sure your doing it right, and take the time to go and get the bits you need, its always better to do it yourself than pay someome else. Then if anything happens, you can say "oh yeah its coz of this..." or "shit i forgot that! no worries i can fix it" etc..

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
