i have standard rb26dett engine on gtr33 with bleed valve, power fc, adj cams, high flow 3 3/4' exhaust and just got a pair of -9's from Osaka Imports today for $1500

Just wondering what kW am i looking at once the turbo's and dump pipes are installed....

and how much without the dump pipes.....

been told that by installing dump pipes, it makes a difference....

need to know what other supporting minor mods can help to increase the power......

thanks guys :)

Your first concern should be reliability and power being well and truely second. Once all bolted together get a good tuner to sort out a reliable tune.

As for the dump pipe difference, I guess it depends which dumps you have bought - sure they can make a difference but by how much depends on how good they are.

280AwKw would be safe, look upwards of 320AwKw but less reliable, depends how the car is tuned and where the power comes on....no point having 320 when your power is upward of 8000rpm for eg. 280-290 would be suffice with the set up and parts you have.

I definately agree with Ant97GTR though, there is a big difference in making big power and making it and still keeping the reliability, take to a tuner who knows these cars inside out!

Where did you take yours to?

Many people told me that with the -9 on stock motor will be around 280 to 300 kW

I wonder how urs made 300+!!!

very concern and will like to know if you did anything else to yours....

Mine had a built engine, head work, cams, cam gears, 4" exh from front pipe back.

I have seen same setups making 290, friend of mine in his R32 GTR is making 328 with more boost, was tuned from a place in NSW just before he bought it, so i would say a little more boost and head work makes the difference.

Simon from NT Performance Turbocharging in Footscray, they had built some pretty serious GTR's and GTS-T's thats why i took mine there, if your keen i can pass their number on and you can have a chat to them about what was done.

I dare say that yours with head work perhaps a slightly bigger exhaust would make more

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
