At last Baz, It sure took some sorting. Had a look at your line when it was on the hoist at micks and i cant help but think theres plenty left in it just by replacing the standard cat.

Congrats on getting it up and going mate. cya round the switch. :thanks:

thanks Noel. im impressed with it and hopefully i dont lose my licence now haha. Nah i will be sensible.

yeah that cat had been replaced a fair while ago and is a hiflow one, but yeah looks a bit worse for wear.

might have to replace it.

Sure is a bit different then driving the datto ute for so long haha

14 psi

i just know its a gt30r .7 comp housing .82 rear.

there was the initial intention i was going to have the turbo run 18psi but, as mick said and i agreed, i think safety for the engine for now is on the cards.

depending on how the engine holds up i could possibly bump up the boost later, but wont be for a fair while.

Very interesting wat stuff did u have to move to actually mount the gt30 power steering apears to b moved and washer bottle was that all or is aircon removed to run bottom intercooler piping aswell has to b moved?

Interested in maybe doing something similiar in the future just wondered how involved it was from say fitting a normal high flow turbo ie manifolds etc wat sorta budget did u have on this ?

thanks ROry

power steering resovoir is from a r31/pintara im pretty sure, it is metal can as i thought it would survive a bit easy with all the heat coming from the turbo. It has been moved not alot of modifyin was required.

The washer bottle is a cheapo supercheap washer bottle, as the standard washer bottle was too big and didnt accommodate for the r31 accelerator cable, of how i routed it. Air con is still connected, nothing was changed there. Only thing that was changed from the intercooler pipes was the pipe coming off the turbo obviously, and the pipe coming from the tb because of plenum change.

The budget on the manufacture of the plenum, exhaust manifold dump and water/oil lines was roughly 2300. But because of obstacles that i have faced along the way that blown out quite a bit and was planning at a certain stage to roll it off a cliff. But im glad i didnt.

Gt30r id tag is - KE0106j

7001770 5014

But nice curve,how much boost are you running? Im sure you can get plenty more out of that turbo.

Is it a 3037 or 3071?

With that tag number, it is actually a GT3082R, aka GT3040R, aka GT30R. I'd originally suspected it might have been using the 7 bladed TO4S compressor, but it's bigger than that.

There is plenty more left in the turbo, but you'd want to be mindful of surge if you crank too much boost into it. A turbo that size if able to pump more boost at middling rpm should be able to easily outflow the engine's breathing capacity.

Shape of the curve is smooth, and AFR looks well controlled - nice consistent mapping and I'd say some time spent getting that looking nice. I hope your drive impressions are good, and it performs well on-road?

Got any pics with good detail of that exhaust manifold?

Yep with that turbo you will see big numbers.When does it hit full boost.Id imagine 3800-4000rpm??

To be honest i havent had the chance to see when full boost is, been trying to keep an eye on the road haha. But will check next time i head out.

going by feel of the engine it comes on pretty strong and im guessing around 3500-3800.

In regards to surge i havent noticed any of it, but yeah that was what i would be worried about if i did bump up the boost.

Later on i would like to change ECU to another item that has a built in map sensor rather then keep the afm.

Comparing the dyno graph with the car on the road, would have say feels spot on as it hauls ass and is very smooth, no hesitations or any unfamiliar noises.

Mick has done an awesome job in making the Exhaust Manifold, changing the dump to suit, and dyno.

I just hope for now my clutch holds up.

sorry bazza but that graph is horrible,

the power delivery and the AFR arent what i would have expected.

ive just gone thru my graphs from my old gt30 and my new gt35 and at 100kph im up in the 230kw range, while your at 150hp. thats a pig.

just my thoughts

This same tuner doess my 25 to just under 500 hp hp atw's and I can tell you he is very pedantic about the way he goes about it. even at lower boost baz" car will kick arse through the midrange as most of his tunes do.

1 bar is only just starting to touch on the real efficiency in the turbo and i am betting that boost will come on noticeably quicker when the wick is wound up.

He also tunes several of our local community lines around the switch area including several of my buds and does a splendid job particularly of tuning the low midrange area where most of these cars do their kicking. I am keen to see you put a few kays up and then get it back for a bit more oomph Baz, If you think it hauls now it should rock then.

your atmospheric temp and intake tems are to far apart . AT-30 IT-60. need to get this closer together to get a proper dyno result. these figures can show a bit more power than what you actually have.

i should also point out that you have spent prob around $7k on bolt on mods to gain 20 hp.

if you put some more fuel in it to get it down under 12, and then sort out your air temps you probally havent achieved anything.

Im curious as to the reasons the tuner set the AFR's to 12.5, and then told you keep it to 14 psi to keep your engine safe. whats your ignition timing doing? was he finding a lot of detenation above 14?

who did the manufacturing of the plenum and exhaust manifold. you mentioned the price of them blew out a bit, have you found that you could have purchased a extreme manifold and a genuine greddy plenum cheeper then what you ended up paying?

its a great feeling to get your car back on the rd im not questioning that, but the dollars you have spent arn"t on that dyno sheet.

the boost was set on 14psi as my engine is still internally standard, and didnt want to risk blowing it up after waiting 7 months from a previous workshop, which im not going into. As for how it feels on the road compared to previously, is chalk and cheese. Now it pulls way harder, accelerates way faster, and im happy with the result. Also another thing to take into consideration is we are dealing with a 13yr old engine. Im happy that the thing is still going.

majority of cost that i have spent went into labour, fixing shit up, dyno time and the manufacture of a new manifold.

The option originally for me before i started was to purchase a plazmaman plenum, 6boost manifold. But then knowing there was a workshop not far away that could do both, plus making the dump, turbo pipe, intercooler pipes and purchase of oil/water lines made sense to go there.

That didn't go as planned, and then I went to Signature Performance, which Mick had a fun time fixing it all up for me.

Im just glad yes the car is running and to me, and friends that have witnessed it, goes great. Yes on paper it is only an extra 20hp then previously, but it feels a way lot more then that on the road.

The AFR's and ignition timing i wouldnt have a clue on, but I was under the impression that 12.1- 12.5 was good.

I guess a way to prove how the car moves is taking the car down the quarter, which wont be too far away.

thankyou for ya feedback dangerman4, and i will seek some info on my AFR's. air temps, and ignition timing etc.

I was going to say something about this. When I did my 314rwkw run, they were 2 degrees apart. TO have an inlet temp of 60 degrees and airtemp of 30 degrees means the dyno operator was trying to fudge everything so you would get your wallet out faster to pay him. A common practice by at least 50% of dodgey operators out there.

Also another thing to take into consideration is we are dealing with a 13yr old engine. Im happy that the thing is still going.

I was running 17psi all day every day until I installed water meth and increased it to 21psi.

You'll find that a RB25 will take 16psi-17psi easily when tuned correctly. My suggestion is to push the boost to 17psi, and drop the AFR's to 12:1 for safety.

Also, tell your dyno operator to stop fudging the result and give you a real reading. Not trying to bag out your result - Its plain obvious that your dyno numbers mean nothing due to the IT and AT being so far out of whack. Who did the operator think he was fooling? Shits me when they do that.

On a hot stinking summers day, here in far North QLD, my Inlet temps were 37, and the air temps in the shed were 35. You can't tell me its hotter where you are, and your inlet temps magically doubled to 60 degrees. Go and kick that operator in the ass!

    • 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.
