Thats right , my R33 4 auto 4 door now totes an RB26dett :flamed:

Its been a long 12 months since the demise of the 1st 25 , with only a brief (4000 kms ) stint with a forgied 25 ( this is a long , costly & painfull story that I will leave to my Lawyers!) all of which lead me to , with a little help from that zoom article , putting an Rb26 into the 4 door.

Basicly , I was able to fit the 26 into the 25's hole by using the 25 engine mounts & just turning the drivers side 1 around 180 degrees.Then shorten the throttle cable , add a GTR radiator top hose & ta da!

I have retained to 25s engine loom so I can keep the Wolf ecu that alows me to run the auto , we just had to change the injector plugs to Bosch ones & change the function of the 25s VVT switch to now be the air temp sensor :)

Although , with the help of Wolf tech support , I am able to use the 26 Cam Angle sensor & change the way the map reads to Ref & Sync. (instead of the modified 25 cas , used for dual point sensing) which has made Cold starts much more reliable.

The 26 is out of an R33 GTR with 51 000ks on it , stock internals & injectors , & the only mods are GReddy adjustable cam gears.

The GTR turbs were rebuilt using T28 (SR20) zorst wheels & housings because they are Steel , & much bigger!

The auto remains stock ( bigger trans cooler coming) but using Redline Racing ATF

which has practically removed any "slip" on the now quite abrubt Gear changes :aroused:

The end result..........376.9rwhp with boost spikes to 20psi before settling to 18psi

& I am bloody happy with that!

The real test will be Drag combat on the 23rd of April so...fingers crossed no :Bang:

Thanks heaps To George & Sean from Adrenaline ( experience counts)

Bart for crazyimports.com

& Steve from Maytech

& here's the pics GTS26tt

Well done Rep and good to see you using the local boys down there.

I know that Peter Blight has nothing but good things to say about George and his patience with getting it right.

Ohh and Maytech, who who get a lot more business if he realised most peoples working days are 8 till 5 , not 5 till 2 in the morning . lol :)

Dare I ask who the lawyer involves or is it probably someone I already know? :)

Cheers

nice man. Do u mind if i ask wat sort of figures this conversion cost?? I've been thinking about what i'd do if my engine cooked and just wanna know if its a viable option.

Congrats on the figures dude, bet you're stoked!!

I'm trying hard NOT to think about it dude ....

But I think 10k would cover it for a straight engine change ( including the engine that is)

It starts to add up when you go for Modded turbs , Split gate dumps Custom Intakes etc...trust me

Cheers

Yeah nice work troy and good to see it all up and running nicely. It was a nice job Sean and george did on the blue rocket.

So the million dollar question what your guess on ET and MPH for DC.

Plus it will be good to have a couple of the buno boys at DC.

Thanx Pete ,

As for ET & MPH , I'd settle for 12.5 @ 115..... as long as its better than my last run :) (except this is in street trim = No Nos)

I'm not sure quite how bad I want to beat up on it , but lets face it , by the end of the day I'll probably be Stalling it up against the handbrake!!!

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
