Hello

I am researching how to put a rb26 into a r32 gts-t. One thing that I keep reading is to cut the slump off . What is the slump and where is it located? Is it the part where the front steering racks would connect to the engine for 4w drive, that is a part of the oil pan?

What would be the proper way to cut this off? Or do I just unbolt the parts? I have read that some people weld it and some don't. I've also read that some people leave it.

I also read that the oil pan has be to changed to a rb20 or rb25 one.

What I researched also is to keep the RB26 engine harness, GTR harness and dash, bolt on the rb20 ac pump, power steering pump, and use the gtr computer.

Do I have this correct? What bout sensors? I didn't see anything about what sensors to keep or change.

I went through several sources online including some from this forum.

Holy shit.

You really are struggling aren't you man.... How many sources refered to a slump?

The slump doesn't exist. The sump is different between awd and rwd. Which is the oil pan. Which has a diff in it for an rb26. Which you should google what differential is for an explanation. And maybe what awd is as to why there is a diff in the front.

^^^What he said, Judging by your many threads your mechanical knowledge is quite limited and while its good to expand your skills I suspect you won't be ready any time soon to undertake an engine transplant. If you are going to buy an RB26 and pay someone to install it in your car the cost will likely be not much less than if you were to sell your car and buy a GTR.

I am trying to learn things. So even when I research you guys act like a..'s. You have no idea what I can and can't do. So for all of you who want to criticize the f is what I have to say to you!

For those of you who help, thank you

Wow, you do realise before the internet people did stuff by working it out themselves, but yet with all the information you have available to you, you have problems even being and to find and understand the info...

Spoon fed but cant chew and swallow

Yoshi,

There are reasons that several of us have advised you that for the power level and response you are wanting you should put in an RB25. Preferably a Neo. Those reasons are;

1) A 20 will be peaky and not as much fun on the street,

2) A 26 is a shit tonne more work to install, including all this crap about having to fix the sump, etc etc.

A Neo is just as good as, if not better than, a 26. Essentially the same capacity, even better head design, same oil pump and rods as a 26. And at the same time is so similar to the RB20 that things like intake paths, throttle cable, wiring, etc etc all just more or less line up with the original stuff, making the transplant that much easier. Sure, there is still of a lot of crap you need to sort out to put a Neo in, but it is still a lot easier than some of the crap you need to do for a 26.

I will admit that power steering and air-con would probably be easier if you did a 26 (depending on the donor vehicle and your choice of which anciliaries you keep from which engine), but that's about it.

If you don't know what and where a "slump" the sump is then you have a metric fark load to learn before you are even capable of considering this conversion

Again with the neo being better then a 26, proof is all i want, i know a stock neo with stock turbo is never going to make 400rwhp, i have proved a 26 will :/

The fact the you don't know it's called a sump and not a slump or where it is on the engine shows how limited your knowledge of cars is and would be doing yourself a favour buy paying an expert to do the job

Area under the curve my friend. Peak HP is only one measure.

show us a dyno sheet that can match micks curve and power out put then cause none seems to be able to come up with them

Solution is simple, do what most to when they have no idea, pay a professional to do it for you.

All you need is money.

If no money, then borrow from a bank, if that fails, rob bank or sell arse or sell drugs to get money. :)

If that fails, sell car.

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
