Not sure what you mean by "Wich version, the standard, or s, sh or l2" :)

Yes i am sure: The comparison was done on two std rb20 motors with different bolt-ons, on the same dyno, on the same day. The graph shows that the GTRS lagged the TD06 all over the rev range.

I have even driven the two cars (at different times) and the difference is very noticeable.

TD06 17C 285kw

TD06S 20G 317kw

TD06SL2 20G 317kw

TD06SH 20G 330kw

rated at the compressor :ermm:

Part number for the RB20DET R32/(and yes it will fit the R31) kit

- Intercooler piping is more suited to a silvertop (r32) engine however.

I have my sights set on a tdo6-20g 8cm LS2 if i have enough by xmas i think i will go rb25, manifold, ex gate and tdo6! Umm.... i am hoping mercury motorsport and just rewire existing loom which should give me more displacement and hence more torque down low. z32 should help with the tuning and the tdo6-20g 8cm might be small on the exhaust side however external gate might help! :D i welcome any input either encouragement or discouragement.

what sort of piping?

The trust kit for R32 TD06 20G L2 will incude, turbo, manifold, dump/front pipe, wastegate, intercooler piping (for stock plenums) oil lines, block off's for water lines etc etc etc.......

As far as purchase goes, there are quite a few retailers / workshops that can get the kit for you.

Im personally going to see how I go with the 8cm rear and if need be get a 10cm housing later on :D

Is it possible to fit the greddy turbo to a low mount cast iron hks manifold? Is there a special turbo elbow needed?

And what is the difference between the s and l2 version? It looks to me there is a model with internal wasteate available for s the s type, but not of the l2 type.

11500205 is the l2 for rb20det. Will it fit standard t3 manifold and standard type turbo elbows?

it would be a big pain in the ass to fit the td06 on the hks cast.

you have to be prepared any turbo on an rb20 is laggy.

td06 wont hit full boost till about 4500rpm and if u get the kit you better off buying the turbo only and getting a custom manifold made up.

i got 260rwkw with my td06 8cm rear housing.. but that was more than a 6k exercise when you include tuning and all supporting mods.

also budget for a rebuild in the future.

Got a dyno sheet of boost vs rpm and power?

With my car its hitting 18-19psi earlier then it really kicks you in the ass. So even though its got the boost on board, perhaps because of the dynamics of the engine (stroke and cams etc) it doesnt really boogie until 4,500rpm, at which point its making about 200rwkws from memory.

I personally think the 8 cm housing will kill a TD06 setup, will work much better with a 10cm housing. The 8cm housing will not like any boost on an RB25 and will probably trail off power a lot earlier in the rpm range.

But will be interesting to see.

As for the low mount HKS manifold, i think you are really better running something like a 3071 rather then try and adapt a TD06. Hp rating wise they are not overly different and would probably get a similar result.

Well.. my opitions:

1. TD06...$6400 for the entire kit from CRD or 2479 for the turbo itself from ISC performance

2. HKS gtrs from slide

3. 2200 for engine, auto gearbox, loom and ecu, approx 1500 for installation excluding a rear diff change.... (different diff ratios)

This requires diff change, re-wire using existing remapped rb20 ecu and vtec controller for variable cam timing.

I am seriously considering 3. due to the modifying potential of the car however the wiring/tuning seems tricky. 20 ecu with 25 block and vct controller!

On the topic of TD06 L2 and RB20, the total exhaust size with the trust 42mm external gate + trust front/dump (2.5" to 3" where it meets the cat)

So the total exhaust diameter is 105mm where the exhaust meets the gate/turbo.

Is it worth going a 3.5" front pipe back (with a setup like this f**k even pretending you have a cat if its street driven your pretty much f**ked in the ass anyway)?

Side pipe is fine for track but a nice cat back system with a good muffler would be ideal for a nice note on the street. I just wonder if 3" is enough?

3.5" is affordable and doable but theres no point spending money where there is minimal/nill gains.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
