These arent really recommendations , more like questions:)

Any reason why you put valve springs in but kept the std cams?

Also it may have been worthwhile to go a lot bigger then 20 thou, you could have easily bumped up displacement to 2.2L with pistons alone.

Also what have you done in the way of rod bolts for the std rods?

Also i wouldnt decompress the engine any more then the std 8.5:1, also i noticed of late some of the cheaper 3" exhausts are in fact 3" ie 76.2OD whilst a lot of the Jap so called 3" exhausts are actually 80mm...

"Also what have you done in the way of rod bolts for the std rods?" umm nothing i know of, any advice would be greatfull though, just need to know what else is necessary, rods? crankshaft?

To4e? why are people using OLD t04's when there is a shitload of new range turbo's out that spool earlier and produve a much nicer power band :)

sadly enough tho with the money spent on that you could have dropped in a rb25 given it a power fc turbo upgrade with injectors.. and it would probaly go alot harder and easier to drive than the dirty old t04e

yeah, mate, you should do that, it would be really good :)

he wanted a powerfull rb20, he now has a powerfull rb20.

you would be surprised how much money was actually spent.

Either way, were you going to give some advice? thats why we started this thread.

oh- and the to4 is new or...hasnt been used.

is there anything that he could have missed? thx guys.

I put an RB25 into my 32 and was rapped, originaly i wanted to build my 20 and have a crazy 20 but when it came to spending the bucks Ben from Racepace advised me that the 25 will make a bit more power at the end of the day so i was sold. I ended up doing the forged pistons, gtr rods, tomei cams 550cc injectors, power fc, hks 3037 proS, fmic and 3.5inch exaust. very happy with the job that was done going to make about 280kw at the wheels on about 17-18pnds.

could'nt be happier with the turbo choice. Perfect for the street not laggy at all.

I wanted to do the same thing.. get a powerful rb20 in my silvia.. but how ever with the money that i was goin to spend i was better off just buying a 26 and getting similar power out of a stock rb26 with mild upgrades.. and still have a safe reliable engine..

dont get me wrong.. rb20's are awesome little motors.. but they just dont have wat it takes to get alot of power out of

      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.
