Thanks guys.... haven't posted results yet because I dont have any.

Me and Toshi did the road tune, but we only got to 16 psi and then we noticed it was missing..

Fixed the miss and then noticed a few air leaks which I have now fixed.

Now Ive just gotta sort out a boost controller as my EVC isnt working and then Im good to do a proper dyno tune...

Cant wait to see what it puts out as its pretty wild atm and its only on 16psi.

Frys tyres when it hits boost in 1st, 2nd and 3rd.

Going to turn it up to 20psi and see what happens.

20psi? why stop there? lol

keep boosting till you find where it stops making power. tis what I will be doing with my SR SS1PU

On the SS series where people get big boost drops, is it worth trying the Gizzmo IBC-R EBC so you can set the gains

higher as rev rise to try counteract the drop in boost, or has anyone tried one and doesnt work ?, are they any good?

cheers

You need a strong actuator, but it needs to be installed after tuning preferably, (tuners don't like running it up on 20psi or more off the bat.) Once you have the stiff spring the electronic controller may have a chance of holding boost flat.

On the SS series plus other G series, they got updated wastegate setup now. The boost drop on those at about 20psi is around 2psi. If any one's got a huge 6~7psi drop then that has nothing to do with the actuator setup. It means its got some sort of restrictions more likely on the cold side. could be intake pipe, small cooler or blocked/bad/small piping.

You will find that by tabbing a boost gauge straight after the turbocharger and inside the plenum. If there are big differences then that is the problem. I'm seeing this often with return flow and some cheap ebay cooler kits. Reference is in page 83.

Some further updates on building the TD06/67 test rig. Car is now fitted with a Brae high mount manifold with our own 50mm external gate plumbed back with a 4inch exhaust exhaust.

Looks good. It did not come with a cheap price. All including the exhaust manifold, screamer, dump pipe plus installation comes to $1880 plus $250 for the external gate, including the turbocharger this kit comes to: $3230

How ever there is a very noticeable gain in mid top end torque without noticing the lose of response.

I will use this test rig to trail all the TDxx as well as the existing ATR43 turbochargers. This setup should provide the best possibly environment for the performance of any turbochargers, and is whats expected on a welly built track car. The end results will vary if components of the setup is differ.

Externally gated turbochargers are cheaper to produce.

haha dont push it too hard till its tuned :P ecu is map sensor based remember :P

hooo crap. I was red lining it 5th gear and my speedo pointed at 10km/H. Its still using the same turbocharger, external gate was holding pretty flat 20psi, in theory the exhaust side should be cooler compare to stock manifold, I didn't hear any knock, hopefully engine's alright. Or will be rebuilding it again for 2013.

Yes I was sitting in a hoist :P

This is my first batch of 25G billet compressor wheels. I've customized the wheel hub and fitted much larger blade with taller profile. I'm hopping to peek around 400rwkws on stock cams before hitting 7000RPMs on E85.

So dimension wise, do the T67's fit on the stock manifold with a spacer if you have one laying around there?

Are the comp covers any bigger than 3540 .70's ?

(and yeh i know you will say it makes to much power for stock mani, but thats not my question..lol)

cheers

If ron can fit a 5558 between the strut tower with a 12mm spacer im sure the T67 will fit too.

Im confident the comp cover will be similar in size to stao's .70 or a T04Z/precision etc. No issue there.

The issue is more so that the exhaust housing flange will be a different distance from the centre point of the CHRA. Realistically it makes no difference how much spacer plate you use provided that the comp housing clears the exhaust manifold.

It's a large housing, not sure it will fit on the stock manifold...

thats all anyone ever writes..lol, (not being rude) but 3540's fit on stockers, surely it can't be to much larger(if any)

be nice to know exactly by someone that actually had both for once, so its not misinformation.

Not thinking stocker mani, be interesting if it fitted on a BREA or NZ style sidemount

the 5558 would be .60 3076 in size would it not?(thats what it looks like in pics) , bit smaller than the .70's

cheers

Hey Stao, I'm still digging the development your pooring into your products..... AND freely sharing the info.

I'm hoping you have a little something in your bag of tricks that can help me..

I drive a S2 (rb25 neo) stagea as a daily... usual mods (fmic, full 3" exhaust, nistune, fuel pump etc...) Do you have a bolt in turbo option/combination that will come on power earlier than the standard turbo? But still make the same or more power. Essentially making it feel like a bigger engine.

I'd like to cap the boost around 18psi

Cheers

Justin

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
