Thanks Roy! That looks quite nasty.....:(

Will definately do something about this manifold. Maybe I need to make a custom heat shield

Stock one had a heat shield where this does not

Edited by blah_blah

ACL heatshield is awsome stuff, you can bend and cut it into any shape you need :) i also heat wrapped the manifold and part of the dump, used heat shield sleeving on the oil and water lines, aswell as a turbo beanie.

After doing a bit of reading this morning. The ACL Heatshields seem to be the go :thumbsup:

Yeh ACL is good stuff, but with that sort of dump and manifold setup I think you will have trouble making a decent arrangement. Under the sheathing over the coolant hoses going into the firewall std Nissan hoses that have been wrapped in DEI no leaks to further make the new hose robust.

When you are driving arount at wide open throttle for 15 minutes with everything glowing red everything goes to shit. Even loom clips nowehere near the immediate heat sources harden and become nice and crispy. If its less circuit car and just a club car doing track work then the concern over heat control is a little less

Bringing a 6" flexible duct up from the front of the car to dump cooling air in the region can help too. Even if it doesn't noticeably cool the hot stuff, it will take some heat away from the stuff that's not meant to be hot.

Just a daily car doing club track work via SAU VIC and other car clubs.

Winton isn't too much a problem.

But somewhere like Sandown and Phillip Island (Havent been but assuming so) might be

With the stock setup, car was getting really hot under the car and oil temps up to 130 towards the end of the day at Sandown. So would only last about 8-10 mins out of a 15min session before oil temps started to get out of control. This was on a 20c day.

So now with this new manifold, turbo and summer approaching. Hoping heat shielding and an oil cooler will do the trick.

Seems a bit of a waste doing track days and having to pull in early in sessions because your car is overheating

Yeh, maybe...but I don't like that idea on my car. Too much heat-temp cycling. If you run a bit duct so its all low velocity and you dont get cold spots...but not very practical given how busy it all it in there. I also ran my inlet temp thermocouple around the strut tower whilst I was doing my shielding etc years ago and i think the main thing is keep the heat in the hot things and try to have slow heating and cooling....with it protect the things that dont like heat and then typically saloon cars with copious amount of 60deg air coming through the radiator gives enough airflow through the engine bay...for me a better approach since i dont want any ducting etc in my bonnet. But others may be able to make it work

Did some jigging today. I can make TD06SL2 20G / 18G or TD05H 18G into a bolton turbocharger for Nissan Rb engines, how ever only in a 8cm housing at current stage. It will cost $300 additional. Since most internally gated TDxx results are rather disappointing, the ATR series are still better choices of a bolton turbocharger, how ever send in PM if any one wish to get one made and have a go at.

The curvature of the blade is too far curved, specially in a 8cm its going to chock the engine badly, and putting on heaps of load onto the thrust collar. Its good for small engines. Under comparison, the SL2 turbine appears much better for a Rb20/25 motor.

The TD05H seems to pump a fair amount of volume on a 4G63, up to 300kw on E85 from memory (with custom spec compressors).

Trent has also said 280kw from one is not hard to achieve. (TD05H 18g 10cm).

That being said. 280kw from an SR or 280kw from an RB is the same amount of exhaust gas flow regardless. Power = flow. Right?

You have the thing able to be put on, just trial it on your own car and see.

Nope, bigger engines actually result in much high back pressure and lot more heat when constrained by a small turbine, its different when fitted on to a smaller engine. So this turbo might reach 250rwkws on a worked SR20det, but won't be able to reach that on a RB25det, probably going to pin its head off on boost.

This is the new 3inch Vband dump adaptor with a large 38mm internal gate that I've been working on earlier and it is now complete.

The 3.5 inches front pipe that I would like to offer with this turbine housing has been made (by Drifthovic SAU: Abe2 <= this guy also makes stainless stell 3inch lobster induction pipes for high flow and other turbos)

After looking into my Xforce front pipe. it appears it was a straight pipe bent into shape by a bender, not mandrel bents. The area that it bents were only 2.5 inches.

With the new front pipe installed, the exhaust sounded alittle louder. and felt torquier in the mid-upper rev range.

Price for the cnc internal gate assembly is $350

3inch mandrel bend front pipe to cat is: $220

3.5 inches lobster bend (show on photo) is $270.

So for example a ATR43G3 with above assembly and 3inch mandrel bend front pipe would be:

$900 (turbo) + 350 (cnc internal gate assembly) + 220 (front pipe) = $1470

The CNC internal gate assembly and front pipe also fits any ATR43's .82 turbine housings.

This setup will allow the turbocharger to perform much betterly compare to some of the CN imported front pipes.

    • 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).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
