Ah fair enough. I did actually consider it, I was tempted by the price. Unfortunately I'm in the same boat as Trev in that it's not my preferred kit. In any case, I should get my setup working correctly without WMI before I start using it as a bandaid.

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

What's missing from your setup hanaldo? I saw your powercruise video (sounds great) and can see your mods/output in your sig. Looks pretty good to me, just not running as much boost as some of the other guys are.

When he runs more boost it doesn't make more power unfortunately so he has to find what's causing that

Some further evaluation on a ceramic roller bearing PU high flow running stock compressor housing internally gated. The profile of this turbocharger is identical to a G2.5.

I've bought some actuators casings from Taiwan (probably same as Kando ones) and used 18psi high pressure actuator springs in it and it worked well. Best part is that I can add few washers under the diaphragm to load the springs to where I want it to be.

It made 341rwkws on E85 with the current manifold. It is 10kws short and 100rpms laggier compare to when it was on the Brae manifold even with more boost. How ever pretty good result from a stock looking turbo.

Haha thanks for that Kasko, pretty much on the money. Haven't looked into it a lot yet to be honest, graduate from Uni next week and fly out to Europe in 3, so been a bit preoccupied. Intention is to get into it once I get back from Europe next year.

Realistically those actuators are just big casings, the actual diaphragm and spring setups are identical to any other actuators. The best part of it is it allows you to change springs easily and preloading the spring by adding washers under the diaphragm of where the two bolts comes out. But apart from that its no differences to metal casing actuators.

Its probably good for turbos with small compressor housings, But It does run out of room when I tried to use it with a .70 comp housing.

Also our billet 18G compressor is ready, The profile is identical to our SS1PU compressor wheel but smaller in diameter. This wheel is made to flow about 10% higher then original cast wheel, while producing very dynamic on road drivability.

Our compressor casting has also arrived.

Tomorrow I will machine it up alone with turbine casting to have the turbocharger produced. It is currently available in 8cm rear, with 18G or 20G comp and TD05H and TD06SL2 turbine wheel. Price is still at $800 each. PM if any one's interested.

Also I've re-engineered the sleeve bearings with different oil grove for the ATR43xx turbochargers, tested today, which made them have similar boost building behavior as the ceramic roller bearing CHRAs, will get some dyno readings mid week against my CBB result. Free upgrade to all customers.

This project is mainly for Greddy turbo fans, but I don't like copying them in OEM specifications, so I will mix and match wheels plus some customized profiled billet wheels for them to be different. The goal is for dynamic drivability, Modify housings to fit different types of vehicles, and perhaps adding ceramic roller bearing cartridges.

I've had the T518Z billet version finalized today with every thing machined up nicely.

It is currently on 18G compressor with a TD05H turbine. I will machine one more housing using SL2 turbine tomorrow

      Shifting questions

      By DRoc81 · Posted

      This was a huge help.  We followed the steps,  although shifting into 2nd was actually into 3rd for us,  and 1st was into 2nd ( steps 9 and 11) .  The long flash was the 4th flash.  So shift solenoid A is possibly the culprit.  Is this inside the transmission itself? Or is it accessible by just front the pan? Or is it bolted to the outside of the transmission?  Thanos for your help everyone

      Can you enlighten me on your best practice regarding these hoses? I don't wanna make the same mistake if you already got a better solution.

      I have some silicon hoses already, for example engine to watercooler. But yeah, I get the sentiment. The lower intercooler silicon hose is drippy too, despite not being very old. Does anyone except Nismo make these same lines out of rubber? Long term I think they'd be the better replacement, especially since the car won't live as hard a life anymore as in the past nor be driven as often.

      I know most issues are just age related. But for example the turbo oil drains, there is dash adapters for these and you can just make a braided teflon line for them and (probably) never have them leak again. Also not terribly expensive. Can you even get the factory hardlines from new? Or are they repairable if they break?

      I know it'd be much much easier with the tool. I hope I can find one that won't take 3 weeks to get to me an isn't a "Asian models kit" that has tons of (to me) useless adapters for a load of cash.   It's a summer project/fun car. I do wanna enjoy it, without endless downtime over and over. So yeah I would even go and buy an engine crane + stand to save myself the trouble of hard to reach or unreachable places going bad later on. Would also be a good opportunity to put on a Fluidamper, renew the mains seals and stuff like that. I have some money on the side that I can use for that, what I wouldn't want to or be able to do is let everything be done by a shop or have my engine completely rebuild right now. I intend to do most of the "doable" jobs myself. Pulling an engine can't be that hard, can it?
