Hi Guys,

I'm new to site, I've had a bit of a look around and can't seem to find the complete answers on most of the posts.


I have a 1993 S1 R33 skyline running a pretty much stock rb25det

Right, so my idea is that I'm after 250rwkw+, anything on or over that, I'll be pretty happy with.

As I said the engine is pretty much stock. Only mods it has are:
Splitfire coil packs

Heavy duty clutch

3" exhaust

I have on the way a front mount intercooler and a triple core aluminium radiator and I also have a Power FC

My plan was to help me get to 250rwkw+, I would run a setup similar to this:

Power FC

Front Mount 600x300x76

Aftermarket radiator

Split fire coils

HD clutch

3" exhaust

Deatschwerks 555cc injectors

Bosch 040 fuel pump

Standard Motor
Standard Cams

Standard intake and exhaust manifold

and of course a bigger turbo

I'm trying to be on the tightest budget possible at the moment without doing anything completely dodgy and cutting too many drastic corners.

To any who have or are planning to go down a similar path, what do you think this set up will be like and what other things can I do to make it a more successful setup?

Also with the turbo, I'm after opinions from people on their experiences with different turbo's. I'm after something that isn't going to lag heaps but will spool up around 3-3.5 and pull right through to 7.
Something with some good torque that will throw you back in your seat but will keep pulling hard until limiter.

Pretty much I'm after the right turbo to complete to combination and get the best results. After the best bang for my buck.

The right combination is obviously going to give me the best result so any help would be greatly appreciated.

Sorry for so many questions in one post just after the right info.

Thanks everyone in advance,

Ryan :)

Hiflow your standard turbo. Hypergear is probably you'd best option. Although if you can find a HKS gtrs or 2535 there fairly good options for 250kw. With the deatchworks 555cc injectors why not go slightly larger? Like 740cc's or I'm sure deatchworks even do a 1000cc option in side feed stock fitment. Although I'd ditch the the side feed option and go top feed rail with ID1000's. Are you going to run e85? If that's not available I'd run water/meth. You'll yield more power and have less chance of damaging the engine. You'll also need to replace the stock rubber turbo inlet pipe with a metal one as the factory pipe tends to start sucking closed up around the 220kw atw's power +.

Yeah hi flowing thw standard turbo did cross my mind bit why pay $1500 to make the standard tuebo better. I mean yeah i think on average 240-250kw is found at around 18-20psi with the hi flow but i could get something else for that price or a little more and possibly see over 260rwkw.

I was thinking something like a gt3037 or something like that. Theyre the same price as the hi flow and could possibly yield better results in the end.

The reason i was only going 555cc injectors is because I am using the car as a daily so im after not great fuel efficiency but a reasonable fuel efficiency. Just trying to find the happy medium pretty much. Good horsepower without the really really crap fuel efficiency.

Cheers

Injector size has nothing to do with fuel economy mate :) Ive got an evo 9 and when it was 100% stock was getting around 350-400km outta a tank im now using E85 with ID2000's and fuel economy is around 320-350km to a tank.

Obviously the extra fuel usage is cos of the ethanol and extra 120kw lol!

Buy a hypergear ss1pu it will make 250rwkw's easy I am just under 300kw's on it and climbing.

Get bigger injectors as when you get to 250 you will want more buy 660's or 740's otherwise you will kick yourself later for having to upgrade them again.

make sure your exhaust is full 3" not just a catback, get a quality cat converter too.

What a nugget :ph34r:

extra 120 killerwasps?

I wasnt claiming 120kw just by swapping fuels that was from stock to where it is now! So relax before you all try flaming me lol! My whole point was about fuel economy :)

Lol yes its still a stock turbo nugget Matty :(

250 rwkw is not hard or really that expensive, shop around for a second hand highflow turbo, a decent front mount, 3 inch exhaust, 850cc injectors, 044 external pump or 040 internal pump, z32 afm, nisstune or apexi pfc and u will hit over 250 rwkw EASY.

guesstimation on prices

turbo $400 to $800

Injectors $300 - $500

fuel pump $100 - $150

exhaust $200 - $400

Front mount $150 - $300

z32 $120 - $200

ECU $350 - $700

Tune $600 - $1000

All up $2200 to $4000 and would only cost you $4000 if you just didn't shop around properly.

My 33 drift car netted 280RWKW with the GCG XTR S1 turbo, jecs 850cc injectors, 044 pump, z32 AFM, Apexi PFC, hybrid front mount, no name 3 inch exhaust and an E85 tune from Garage7.running 19psi

All up cost to me was : second hand GCG $700, NEW injectors $550, Z32 $110, 044 pump $120, Hybrid cooler with piping $200, APEXi PFC $700, free exhaust and $600 for the tune. All up was just under $3000, and I didn't really shop around, just grabbed the items when I saw them for sale.

Something worth considering is the dollars spent to support 250kw.

The same or similar supporting mods can support 300kw+

e.g. Apexi PFC, z32, FMIC, Exhaust, upgraded injectors,and fuel pump etc.

Your turbo choice will be the biggest determining factor. Notwithstanding the mods above, the other is fuel choice i.e. 98 vs. e85 with the appropriate tune.

I found it very helpful worth investing the time to take a look at Dyno Thread.

You may notice a pattern of the turbo selection and fuel choice for those making 180-220, 230-70, 280-330 and so on.

See if they meet the 'response' your after at the chosen power level. I would argue pegging your power level a little higher at say 270KW+ and put those supporting mods to work.

Admittedly I went too big for my setup for my original power level of 260. So I went 300.

Lol yes its still a stock turbo nugget Matty :(

Buy Alex's FP Black :ph34r:

You coming today my man?

Cheers for all of the replies guys.
Had a bit of a look through the dyno thread.

I reckon I will be running bp ultimate or shell vortex for the dyno, but I usually run 98 anyway.

I had a thought about running a gt3076r or hks 3037. Both pretty much the same i'm sure, both turbos are good for around or a tad over 500HP which isn't too bad at all.

I'll most likely go with what most of you said and not limit myself too much on the injectors so I might go larger, something like the 740cc injectors. Just so I'm not maxing out the 550's.

Also I reckon I will be going an 044 external with a surge tank rather than maixing out the 040 intank. From what I could find, 040's are good for 250-270kw which is what I'm after, but a 044 might benefit me in the long run if I decide to keep going up.

Cheers Jim for reassurance of buying second hand, it was an idea in the back of my mind but I just wasn't 100% sure on whether I really should or not.
I've found a gt3076r for $1000 so I might possibly look into that.

500hp at the engine maybe but on pump fuel you will be in the 400-430 region at the wheels.

As for the 044, my single maxed out at 350rwkw (I think that is 470hp maybe or close enough).

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
