Its still the original RB20 gearbox, 180,000kms old. I have run 3 clutches, std, UAS GTR single plate clutch and now an Xtreme single plate clutch. The UAS was better.

roy,

seeing as though you're the RB20/Trust TD06 guru :)

just curious to know, what are your thoughts on how the Trust TD06-25G will perform on an internally standard RB20DET?

cheers.

Id say its too big. But i suppose if you shove an 8cm housing on it, and you can live with nothing under 5,000rpm then it would do the job at the drags. Two friends in particular still rate the TD06-25G as the animal setup on RB25s

yeah, i thought so. it would definitely be more suited to an RB25 or a nice RB24.

Roy, how's yours for cruising with the TD06-20G?

Edited by RS500

I drive it every day, (well i did up until August this year) so im use to it. Better if someone like R32Big_boy, Scotsman, Doughboy Chris32, Bl4ck32 etc answered (if they bother reading Rb20 threads :P)

as they have all had bum in seat time.

Its a nice little thing. If you like punchy power and response it sux. If you are thinking about what you are doing and keeping it in the correct gear, its a good match. Just dont expect to stomp it in 3rd at 60km/h and go anywhere very quickly as the thin only has 110rwkws or thereabouts. But if your doing 95km/h in 3rd the thing has over 200rwkws (from memory)

Actually since you used the term cruising id say its excellent. I can sit on the freeway and get 9.1L/100km, and drive smoothly along without filter and BOVs makign lots of noise ramping onto boost. It makes for a nice street car, just not a very quick one.

I dont think too many clutches will have troublw holding the power a TD06-20G will make on an RB20. That said mine when it got a bit hot at the drags did tend to slip a little, but its fine on the circuit so im happy. If it slips then its helping my gearbox live.

It seems the secret to helping the RB20 box live is not to over clutch it and to keep good fluid up to it

Driving up to 20km/h in 1st gear then grabbing 2nd and florring it, i get no wheelspin in 2nd as it ramps onto boost. Shirting into 3rd at full noise etc, traction is perfect. I run RE55s, and to be honest i dont know how well the 18" Falkens hook up on the street as i havent really given it any stick.

The R32 chassis with reasonable tyres wont have too much probelm with 230rwkws.

thanks for the info roy.

given that i drive a sierra cosworth rs500 almost as an every day car, i am used to having lag and it not being so punchy in the lower rpm range, so that won't be a problem for me, although as i am looking at buying an r32 gts-t as an every day car and potential track warrior later on, i'd like to go for a setup that will be better than what i have now with my cossie.

i actually like how u mention u can cruise on the fwy with low fuel usage, as i'm looking for it to be quite economical when the power is not needed.

im slowly setting my car up to drift...just trying to get the motor upto it....and i dont care about lag with drifting...cos most of the time your on full boost anyway....but if it could start to break traction in 2nd that would be nice cos it would make it easy to slip it out sidewards

and i dont care about lag with drifting

?

um. Sorry, but, like, you have so totally got to do some research.

you need control to drift. unless you just want to hang the end out from time to time.

then again, what would I know?

i know where your coming from...as i have drifted a few cars they dont have much lag if any at all...but i dont mind lag...you control your drift with throttle control....and use a bit of brakes at the same time....drifting is better when your at full noise and the tires a screaming out smoke....most people prefer to drift and have no lag...but im the opposite

?

dude have u seen what turbos all the top cars run? Most of the top cars D1 cars run 450ps plus which mean td06-20 at a minimum. The ppg gearbox car and the d1 garage s14 and a number of other cars in the aus series all run highmount turbos. Its quite easy out on a race track to keep the engine on boost as most of the time you are in the powerband (if not change down! :D) or you can always kick the clutch :)

If you are serious about using this setup for drift, i would recommend you try and suss yourself out a nice manifold. Whilst plenty of ppl say that the std manifold is good for plenty of power, the fact that Nissan gave the RB20DET-R a neat manifold, and i think whilst there are better setups then mine, the synergy of turbo, manifold and gate work well together. I suspect you wont get the same resutls using the std manifold.

The D1 cars with the larger turbos in the 450-550hp range all use manifolds and gates, which again reinforces that the synergy of all the parts help the setup shine

The above plot is my turbo with the 8cm vs 10cm housing, but since you have cams etc, it will be interesting to see how it goes. The setup is dramatically improved with the right housing

One thing with using the std manifold is that you wont have to go crazy with heat shielding, you will still have to pay attention to shielding for dump pipe etc, but as you can see in the below pic, the manifold exposes a lot of engine bay parts to high temps.

hmm thats a pretty nice setup...the diferance between the 8cm and 10cm is pretty big...im also gettin a custom made plenum to go on with this aswell...im also thinking of ordering a 3 bolt 8cm exhuast housing like yours instead of using the t3 internal gate housing because the internal gate doesnt look like it would work very well...as it looks like it would cause alot of turbulence....if i go with the 3 bolt external gate housing i will get one of those OBX turbo manifolds from the states cos they are cheaper than greddy.....wat external gate are you using roy?

    • Got started on the modification to make these splash plates fit over the long weekend. First the surprisingly time consuming task of swapping all the cam camp bolts to Tomei cam cap studs. I did the method of removing one bolt at a time, applying loctite to the stud, double nutting to torque as the manual described. Then carefully unlocking the nuts without disrupting the torque of the stud (and going back to re-torque a few times when it slipped). Finally applying the nut and torquing to spec. Repeat x28 Next up I went about removing the stock cam cover baffle so I could ensure it was fully clean after drilling for stud clearance.  As the blind rivets holding the baffle on were domed I used a punch to mark the center then used 4mm drill bit to carefully drill out the rivet without going too far part the baffle. As seen in other thread here is what is inside the stock baffles I decided on M4x6mm bolts to bolt the baffle plate back on with. I used a 3.3mm drill bit with some tape to mark the depth at ~8mm. Next was to tap the threads using a cheap bunnings kit M4x0.7. With the baffle removed I also drilled out the spot welds holding in the baffle plate oil returns. Unsure whether this was the best option or if I should have cut holes in the Hypertune splash plates to allow the oil drains to still function... time will tell. I then removed the the Hypertune splash plates so I could rest the cam cover on top and use a dab of grease to mark where the studs impacted the oem cam cover baffle. The most obvious spot was on the hump from the stock mesh is held. Using this hole as an anchor I bolted the oem baffle plate back into the cam cover and lined up the Hypertune splash plate. Marked the rest of the holes for the studs and drill those out too. Total 32 holes drilled and 12 threads tapped on the passenger side cam cover alone for this bolt on part that totally clears all OEM cam covers.. Drivers side next as well as some E85 safe fuel foam to fill the space behind the behind cam cover baffle plates. oh and some lock nuts for the splash plates of course.
    • I had the same previously, and it really shits me. They just run off red book averages or whatever as the maximum insured, there are never good quality cars available to buy for anywhere near those prices. I don't even understand why they do it. Sure having a customer overinsure then false claim is a risk, but how often does that really happen in the world, 1%? 0.1%? On the other hand, all 10-20% above redbook listed prices and charge 10-20% higher premium, surely that is more profitable for those cockroaches
    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call
