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...

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

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
