Have thought about that too, but can't help but feel that there is a possibility the owner will want to charge for more boost at some point in the future. I tend to think of F20Bs and more so H22As as parallels of RB25s, which I'd probably not put a TD05 on either. I think in this case a little more lag and more than enough flow would be the preferred, but still pondering on it.

.... the brutal hit of the 20g.

LOL, I wish it had a brutal hit :) The car that I drove years ago that made me go TD06-20G was an 180SX Jap Drift car and it did come on harder then the RB20...but wasnt as brutal as say an RB25 with HKS 3040...that came on HARD!

Re the low boost Honda. As a rough guide my thing makes 180rwks at 8psi. 225rwkws at 14psi and 260rwkws at 19psi...roughly. So they work ok at lower pressure ratios giving you a decent gain per psi even at low boost

Roy - cheers, thats the 20G with TD06 hotside - right? Thats one of the reasons I am pondering the full TD06SL2 20G, an 18G etc will make >230kw - but they may need the boost more. The Honda needs decent flow at lower boost, and they drive turbos reasonably well. If we went TD05 (or even 06) with an 18G compressor and found that it isn't flowing quite as much as we need then that would be quite a pain. If we go TD06SL2 20G its going to make the power the engine will want to make on 11-12psi as far as I can tell, but it will be less responsive than the 18G (esp. TD05 hotside one), which relatively speaking is probably less of a fail as I can't see the TD06SL2 being terribly laggy relative to rev range.

The trick here is the current turbo on the car is a Chinese 700hp something or another, so anything compared to that is probably going to feel supercharged :) The other thing to remember is with a filthy Honda, with this car the party starts at around 5500rpm and redline on this fella is 8000rpm regardless of if or what turbo is on it.

Appreciate any thoughts or experience that might help with this, as at the moment just trying to make the best educated guess.

Do you really peg the H22A with similar character to an RB25? That's some jump.

If its good flow at low boost I would be thinking larger compressor smaller turbine. Maybe TD05H 20G? I can only see this as a negative if the user wants to access the upper most regions of the compressors flow capacity. Remember again the Evos do quite well out of the little TD05H :thumbsup:

I'm not actually sure what you're saying by saying "Thats some jump", surely you aren't talking about an RB25 over an H22A?

Yeah, I had thought about the whole TD05/20G idea as well and still think its well worth considering though mindful of the fact that 240kw @ wheels on an EVO is pushing the old TD05s quite hard while there is the possibility we could be looking at numbers in that range from the Honda and really keen on ideally not becoming knock limited - or at least minimally so.

I owned a H22A VTEC Prelude in Auckland for 4 years, damn nice cars, and the H22A really gets going after 5500rpm - almost turbo goodness - they are quite high compression engines though, I take it that your friend's block (talking to you Lithium) has the compression lowered as its already turboed??

Yep, around 9.5:1 compression - and yeah, they are very good motors and have epic potential. My flatmates Prelude makes in the area of 190fwkw, which would be respectable for a turbo 4cyl even :)

Thats a bit hard to digest, from the factory they are 150kw at the engine, lets say this is 110-120 fwkw, and since Hondas are NA and so well tuned and designed from the factory, no amount of headers, exhaust, intake and VTEC controllers is going to net you that much gain over stock (unlike turbo cars), I think roughly even 30fwkw gain over stock is huge for a Honda. If that Prelude makes 190fwkw without a turbo (unless its the same friend with the turbo H22A?) then thats either pretty phenomenal or too good to be true..pinch.gif

Cheers, will tell the owner that... he gets a kick out of people being incredulous at the results :D A huge amount of work into it to get there - it goes a tad beyond exhaust intake and VTEC controller but no its not the car we're matching a turbo for so a bit OT, was pointing out these things can breathe something fierce if they want to.

gtfo with all your Honda talk.

with the lovely day yesterday with dry roads, i was able to test the current tune on only 14psi and it is very responsive.

will be interesting to compare graphs with mine and a gt3071 to compare boost/rpm when i get it.

cant wait to experience the full tune of 22psi in a few weeks!

will be lots of fun.. :devil:

oh and the car sounds extremely g4y with the gate plumbed up, it needs to scream!!

I always thought you were the boy who digs Hondas.. On a different note, its good to hear you like the Kando TD06 on your 34 Neo, thats the way I'm sure I will be heading soon.:yes: From initial impressions, does the boost and 'torque feel' ramp up hard and aggressive or is it the boring linear feeling turbo that some people love??

Roy, can you please post up your latest td06-20g dyno graph so i got something to work off :)

Will be interesting to see the difference. I only have road speed graphs which normally look ok ithrough the mid due to the shorter gearing and 17" wheels.

This is my current one, running Plazmaman, 6boost and the difference is 98 and ARC cooler vs 100 and R34 GTR cooler.

This gives you an idea of how much I lost with the Plazmaman and 6boost manifold

LOL, so looking at the above graph you may start to understand why sometimes I seem like an argumentative bastard with looking to quantify results or asking questions. I have spent about 2k on manifold changes only to lose power and response and make the car more sensitive to ignition and detonation :spank:

agreed the honda product is hugely underated.. People in the states slap a turbo or 2 on a v6 accord and it easily pokes out 300fwkw...and there inlies their problem "FWKW" as useless as a one legged man in an ass kickin competition..the day they put a diff in the rear end is the day they get the notoriety they deserve..

yeh mate, comes on hard.

you will not be disappointed if you go down this path.

Good to hear you sorted your boost problems mate. Keen to see your dyno results! What rpm are you hitting full boost by with the TD06SL2-20G?

did a test last night,

in 4th from 2000rpm flat foot, it hit full boost by around 37-3800rpm.

    • Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging. Cheers 
    • I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
    • Luckily I didn't put in etch primer as I just found out it's not compatible with my body filler lol. Also just need to sand the panel anywhere between 150-400 grit so I'm in the clear there. It does say to not apply to soft old paint, I assume that means paint that is flaking, peeling,etc
    • @dbm7 and @GTSBoy thank you both very much! will give that a shot!
