Yes I have the twin scroll TD05-20G and it's been working great for about 3 months now. Quite a bit more lag than the vf37 but the top end gain is great. I think I'm hitting full boost(24psi) around 4200 rpms but i think my downpipe to turbo exhaust gasket is leaking so that might be causing a problem. Also I'm running E85.

That's a lot of lag... Friend with the MAP billet 20g is 24 by 4k . Haven't had a chance to log transition response yet so can't comment there

Update for you guys: We have 10 of our adapter flanges ready to go (some were shown at Wicked Big Meet) and the production for our TS specific downpipes is underway. We're about a month behind where we thought we'd be, but the big part (custom cnc'd flanges) needed to be right. Shoot me a pm with any questions and we'll keep you posted with info, photos, etc.

No I don't recommend the one I'm running. As soon as I get back from Singapore I'll be taking it off for the VF37.

My tuner said he could have made almost the same power on the vf37 that he got out of the 20G. He has a very good track record with me and his cars, he knows his dyno. So all in all I gave up spool to gain very little power. So I now have a $1300 paperweight

i dont have any experience with the avo actuator but i am running the kinguna what ever the name is 1.2 bar actuator and it seems to be working pretty well. at least way better than the factory 8psi pos. i peak 23psi and hold 16 psi to redline. thats on e85!

so the top end isn't really that impressive ?
i mean i read that some guy hit 370whp with this turbo . . .
and how bad the lag is on the ej207 ?

The top end holds till 8500, you'd just have a more narrow powerband. Keep in mind my turbo is tomioka racing, not kinugawa. Highest I've seen on tomioka's 20G was 354 on E85

get a larger DP/exh. i have been running what i thought was a 2.5" old ass aps exhaust with a 3" downpipe. it taper down to 2.25"ID a foot after the bend at the bottom. my spool is about 20psi at 3350rpms on the vf37. when a friend on here was getting that on single scroll i knew something was up. went with a cutout right were it tapered so now its full 3" for like 4' of pipe. should be fun to try at the track soon! hopefully i can get the spool to like 3k rpms for 20psi. 5k rpm powerband!
also going to speed density this weekend as well so that should be fun! crazy launch control, no lift to shift, and maybe antilag once in a great while will be fun with a cutout!

yeah for us poor college kids we make a bracket and use a spring that increased it to 15.5 psi actuator! thank god i tune myself otherwise this prob wouldnt have ever happened!

That's exactly my sentiment. Upgrading of turbo with no change in pipe, will the 2.5" exhaust pipes becomes a restriction.

Just the downpipe and turbo, stock headers.

No info on the kinugawa, can't say yay or nay, sorry

fujik can help you on the kinugawa turbo. he ran the 20g for a while. said it wasn't bad but not the best either. the really best option for TS stock exh mani/up pipe is the dom1.5xtr right now. on race gas/e85 you should be able to hit 400whp and it will spool by 4krpms. pump gas 350 should not be out of the question either.

I second this, and echo the age-old saying "you get what you pay for."

That's exactly my sentiment. Will there be benefit by just upgrading the turbo without upsize the pipe as the pipe will likely to be the choking point.

At these power levels I'm really quite shocked too see such a marked difference in his spool characteristic. My tuner ran 2.5 pipes up to 536whp, changed them out for larger pipes and gained less than 1% power increase. Spool actually got a tad slower

larger pipes will slow the spool because the same exh gas can travel slower since the inside cross sectional area is larger. so the exh travels slower into the turbine, spinning it slower and slowing down spool if your running the jdm TS up pipe or anything over stock up pipe you should be good. the next point of choking is the downpipe/exh. like i said my exh was slowing my spool down because it couldnt shuve the air through as easily as a larger 3" exh.

as far as an up pipe for what you all prob do the difference wont be noticable w/o a log or dyno. there is a fine mix of diameter were if its too small it will increase exh gas velocity but will overchoke the engine. too large and it does vis versa. the turbine is enough of a resistance to air flow so i would go with like a 2.5" on SS and the stock TS setup. As far as spool characteristics post turbo the td04 i had on e85 with tons of porting. large UP, and ewg spooled at like 2700rpms for 22psi. when i took the DP off it was even faster but obv not practical. hence the cutout i am putting on my current exh for the vf37. the turbine is less restrictive than that of the td04 turbine but still plenty.

EWG would be the next best thing to help relieve pre turbo pressure and that is were you will see HP increase. TS will require alot of fab work to run the dual WG or some very precise welding to bring two pipes into one and making sure they keep the pulses seperate. but thats a different thread.
