Both those graphs are my 20G. I dont have results for my 18G. I gave it to a friend who is going to run it on his SR20 Cortina :)

The Plazmaman plenum is actually laggier than std but the curve doesnt nose over at the top. For me I wouldnt put a plenum on an RB20. You lose torque and the only way they end up faster is if you absolutely flog the guts out of them with revs. I used to use 8,800 in 1st, 2nd and 3rd gears and about 8,000 in 4th gear. If you care about the life of your engine I am not sure that is a good recipe for a std engine with std oil punp etc etc and 23psi

No worries!

In the case of the 18G I have done I honestly feel that the stock position housing could be holding it back somewhat. I have no evidence to back this up though. It made roughly 210kw with ease on a Mustang dyno. I've noticed knock here and there recently so may speak to Jez about a touch up on his current dyno.

You make me wish I'd gone a 16G6 on that car though :)

Yeah, I had figured that I'd rather a 16G6 + TD06 housing than a stock position 18G for the same reason - the 18G is rated at around 40lb/min, the late 16G6 compressor maps show ~41lb/min at 2.4 pressure ratio, so it has all the flow we'd need at the boost range we'll be working with.

Lith stop giving me regrets! LOL it seems the 18G is obsolete, unless its completely application specific.

Kane the graph looks tops :) Good stout power for an RB20. Keep it on the boil and that would be a very quick car.

Stao should make bolt on TD05H 16G6 turbos for RB20s the same way he used the T28 housing to make his SS1PU.

The revs and road speed dont quite match my run on a Mainline dyno with std diff and 235/40/17" RE55 semis. My road speed and revs match up prety well according do the AiM dash so I suspect your car may actually be a little more responsive as I suspect the revs are calculated from road speed? so perhaps a tad wrong with the rpm? I dont know how the Mainline dynos work out rpm.

Did Jem seem to think cam gears are a good option? I would be doing that years before I think about putting a FFP on a car

Ordered a td06 20g 10cm for my s2 rb25 now I have sold my other turbo that I wasn't going to be happy with the out come. Staying pump fuel for the time been and hopefully pull 300kw out of the old girl but ill find out in time, still have a a lot to do before the tune next year sometime but I can't wait to see the results.

Does anyone know if kando dynamics do front housings on their own?

I know they do rear housings, because i was thinking of changing a XR6 turbo to a the larger .70 front housing and then using the smaller .82 rear housing rather than the 1.06 they come with stock to compensate for the lag on the larger front. Just hope he .82 won't be too small for the 4L.

There is very little lag with the larger front imo, it simply slows the air speed down a little in the outlet pipe due to the extra area. I have an aftermarket 0.7 housing here for a GT35 if you want to try it out before swapping the rear.

AFAIK Kando don't sell a 35R front housing on its own, and from memory the XR6T CHRA isn't a normal GT DBB core... So the backing plate on the front housing MIGHT be different. I really stress the might...

In terms of lag, I believe only initial spool up from idle/cruise conditions will be effected and only a minor amount. To my knowledge the larger housing will actually have better boost recovery (response when at speed).

That being said, you should hit up Scotty for his :)

check with Stao?

mates, please help me.

so there is a big chioce of TD06 types turbos with anti surge, 15G 20G 25G and so on. but as I understand all these needs the wastegate (better then actuator), custom manifold and down pipe - am I right?

second question - if to choose the TD06 series - which model is the best one(minimum lag, fast spool, optimal for rb25det neo)?

and the last question - doen anybody have experience with bolt on one (dyno graph, feedback) : http://shopping.kinugawaturbo.com/upgradeturbochargerrb20detrb25detwstage3turbine68mmcomp450bhp.aspx

i checked the size of compressor and turbine - they are similar to Greddy TD06-20G:

http://www.ztechz.net/id1.html

The only one that is a 'bolt on' turbo is the one you linked. It is a T04E stage 3 turbine with what appears to be a 20G compressor. It has been hypothesized that it will make a good highflow and fall between the performance of a GTRS or 3071. So likely to achieve 270kw when pushed and reasonable response.

However, we are yet to see an actual result from it. I believe one was posted to FB at some stage but it hasn't made its way to this thread yet.

If you looking at something of highflow level have a look at a Hypergear. The highflows he does are tried and proven, with countless positive results and good feedback. A safer bet IMHO. His thread is on the main page like this one.

Have booked the dyno to tune my mates S14 with a 8cm TD05H-Evo3 16G on flex fuel, we will go to full E85 and at this stage may go up to around 20-21psi. Will post results for that when it's done.

Do people realise (or have any thoughts) on the sentiment that the Evo3 16G is often considered to flow similar to the 18G? This fact was part of the grounds we chose the Evo16G compressor over the 18G though will soon enough know if that was folly. So far it happily pumping enough air to keep the SR20's thirst for air quenched, so seems good so far.

Also, I had previously posted ~3700rpm for full boost - that was rolling on throttle, later testing showed that it gets 19psi by 3500rpm in 3rd gear and holds power nicely past 6000rpm, compared to the old PE1420 which hit a wall before 6000rpm.

This turned out to be a very frustrating day on the dyno - after doing plenty of testing on the road before booking the tune etc, the thing decided to be a dick on the dyno and we lost a good couple of hours trying to resolve a major boost creep issue that we had never seen before. We ended up giving up on doing that with paid for dyno time (quite hard to secure a booking for this kind of thing) so we decided to try and make the best we could of the situation, which ended up being able to hold roughly 16-17psi up to 5800rpm and then try and get the boost control sorted later, then just tidy up the last bits of fuelling on the road as the main purpose of the dyno was really to get a picture of what timing the engine wanted on a variety of different loads and ethanol blends - which we achieved.

End result on E77 was 250kw @ 5800rpm running about 17psi with full boost at 3500rpm on a 9 second run which is pretty decent, I reckon. Power was still climbing with more rpm, so if we could have held 17psi the full way it would have made more than 250 at that boost level... and it was also very keen on power gains with more boost. We saw over 270kw on 20psi with soft timing at just over 6000rpm before we gave up on trying to tame the boost control, so there is plenty more power in this setup.

Unsure at this stage whether the issue is a Kando Dynamic quality issue or if something else in the setup decided to be funny, will update if it turns out to be a Kando fail however it must again be noted that the car never previously had a boost control issue - though it does sound like it may have developed a few days before the dyno and at the time the owner thought nothing of the cut out he experienced thinking it was something else.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
