Hi

My name is randall and I own a 1994 Skyline GTS-T (RB25DET) .I live in The Netherlands and there are less than 10 skylines in this country, thats why I'm reverting to Australian help..

I've pulled the car apart completely and going to have it painted and then rebuild it completely.

Now I've come to my engine, disassembled it and building it again now, installing arias 87mm pistons, crower rods, new bearings, grex oil pump,N1 waterpump etc.

Cilinder head will receive flowjob with greddy intake manifold tomei springs (want to up the rpm's) and in/ex cams 256in/264ex.

Blitz front mount intercooler, nismo 740cc injectors, Z32 MAF, Apexi power FC. PWR Radiator.HKS full race exhaust, cat replaced by straight pipe.

Now my question is; (and yes I've used search) for approx. 450-500 rwhp can I use the greddy TD06SH-25G 10cm full turbine kit?

My demands are top mount manifold, not to laggy( want to drift) boost coming in at 3000..... but am afraid with an 8cm turbine housing the turbo will choke at higher rpms.

I am a huge fan of the Greddy kit but want to hear first hand experience , since all the skylines over here are bone stock...............

Thanks

thanks, read all 3 pages of data and comparisons and trying to make a solid decision based on my needs for the car...read that boost starts at approx 4000 rpm, which in my opinion could be realized earlier by a quick spooling BB turbo with a smaller turbine A/R.

Can someone tell me if a greddy T78/T88 manifold flange is similar to a T4 garret flange? I believe so.

So if I were to buy a trust T78 manifold for the Rb20DET and fit it to my RB25DET and add a T4 BB turbo with a turbine A/R size of around .70-.80 and a compressor big enough to realize 450-500 whp, would that work?

      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

      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.
