Looking at fitting either of these turbos to my RB20. Any feedback from people who have experienced this engine/turbo combination 1sthand? I have been told I need a spacer plate for the Trust turbo but does anyone know if it will fit up to a split dump pipe? Any help would be greatly appreciated

Ive got a GCG hiflow on my RB20. although it's not tuned yet so im only running 10psi.

but even then it goes alot better then the standard turbo ever did on 12psi and pulls all the way to redline.

Less response of course but not as laggy as you would expect.

Here's a link that gives some idea of the different impeller sizes on the MHI/Trust turbos vs Garrett.

http://www.900aero.com/main/tech_main_turbo.htm

I think a lot of the MHI gear is fairly heavily turbine biased, so Trust use a bit of mix-n-match to chase quick response. Pity that they use the 3 bolt turbine inlet, because genuine MHI turbine housings in TD05 and TD06 are evidently a T3 flange.

The Td05/06 turbo is a excellent match for the RB20 imo. It does require a spacer plate about 10mm just so the comp cover clears the manifold. With supporting mods you will get around 240rwkw. Cant remember about the dump pipe but any decent exhaust shop would be able to make split entry dump for it. Havent had any experience with the gcg hi-flow though so dont know which is better. BTW it is a T3 flange.

I had a tdo6 20g on my rb20 (240kw@wheel) and hated it. Lag, then wheelspin snap. Nothing at all in first gear unless u wanted to thrash the poor girl to about 7500-8. Same turbo now on the 3 litre motor and much much better. Total power not much more (280) but good grunt at 3 instead of 4500 - 5.

I 'think' it's a 10cm, but not totally sure. It was very very snappy on the rb20 tho, real hard to control power in lower gears. Straight line not too bad but try driving fast on a windy road - just forget it - I'd get beaten by a 180kw car easy. What a difference a litre makes eh.

the t05 turbos are a direct bolt on for Rb20, they also come with a dump pipe that joins to any aftermarket front pipe.

the 16g is good for 200-220 at 1-1.2bar

the 18g is good for 220-250 at 1-1.2bar

have used both extensively, and are a great bolt on solution. the 16g is super responsive but runs out of puff up top if you want to make much more than 220rwkw without cams etc.. I find this turbo far to responsive and prefer to use the 18g.

What supporting mods are you running with your highflow? Aiming for 200rwkw's, I am hoping to get away with highflow, fuel pump, exhaust, cooler & remap. Want to leave injectors, FPR, AFM etc. stock at the moment due to money, or lack of. Do you think this would be achievable? Also what is lag like compared to stock?

hhmmm??? 'sif anyone would ever get pee'd f at Aaron, as nice a bloke as you'll ever meet.

I waited 12weeks for one last year (between Aug-Nov) and couldnt have been happier.

Slides overall health is of most importance; yes he does have a health issue and yes he does get very busy with the huge quantities of orders he receives for his hiflows. For the cost/quality of the unit I think its an awesome deal never mind if its a 3month turnaround.

If youd bothered to read his area of the forums, instead of stirring up crud:

"Hi Guys

Orders are now being taken for highflows again

We will not be doing the sort of numbers as we used to so when orders peek at 20 we will stop until all are done.

This is simply to reduce waiting times due to the amount of orders we receive.

The waiting times will always be stated at or longer then 3 weeks regardless of if it will be done in 2 days.

This will be to avoid any possible delays that may push back production including my personal health."

Slide highflow FTW !!11!!!!!

      R34 GTT idle problem

      By Dose Pipe Sutututu · Posted

      Oh yeah forgot to also mention need to also unplug the IACV as well. Thanks for the reminder @MBS206 Unplugging the TPS takes it out of closed loop so you're able to screw down the IACV without the ECU trying to add/subtract timing to maintain the idle (not sure PowerFC can even do this, but Nistune and the OEM definitely does)

      Nissan Skyline R34 GT-T 1999

      For sale is my 1999 Nissan Skyline R34 GT-T, tuned to 234 kW / 313 hp. I've had the car for a few years as my daily driver. The car is original (as far as Skylines go), with only a few minor upgrades to enhance performance and driving experience, as typical for such a car of its age. Overall, it is in great condition with no body rust, thanks to its earlier import date. It features a top-notch security system (not literally, but it's great!) with remote start and still functional 4-wheel steering via HICAS. It comes with several performance and handling upgrades, including:     Hypergear 450HP Turbocharger running 17 PSI boost, installed mid-2021 by Jaustech     550cc injectors     Nistune ECU     Front-Mount Return-Flow Intercooler     X-Force Stainless Steel Exhaust     Upgraded engine mounts     Bottom end bearings replaced     BC Coilovers     Lenso DR1 rims     Bridgestone Potenza Adrenalin RE003 TL 245/40R18 97W tires, fitted early 2023 The interior is mostly stock, with a few additions:     Viper Satellite Tracking System with remote start     Bluetooth Double-Din Touchscreen Head Unit     Steering wheel cover Cons:     A few paint imperfections here and there     Driver’s seat shows more wear than the others. It's not torn at all, but I've added a seat cover to protect its condition. I also have a CarVX Vehicle History report available for serious buyers, so you don’t need to purchase it yourself. Price: $26,000 ONO.

      Troubleshooting - motor wont turn over

      By TurboTapin · Posted

      I've had two suzukis in the past have an extremely hard time turning over and not starting after sitting for a few weeks. Ended up the alternator would seize up causing the starter to force. Same issue both times.  Maybe they're sourcing their alternators from the same place...

      R34 GTT idle problem

      By MBS206 · Posted

      On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
