Presuming i have a complete rb26dett turbo's n all, can anyone give me a "rough" estimate of cost in putting it in a GTS-t? Not including supports such as brake upgrade and engine supports (cooler, fuel, clutch etc) just having the motor running in the car.

Anyone here personally done this?

My main reasons for wanting to do so is that i can get the car pretty much legally registered with around the same power i have now on stock turbos, plus i like the twin turbo power delivery in a RWD car, plus an rb26 is just cooler :P

cheers.

i realise this is not a cost effective exercise.

Well motor in/out generally people stick that around 1k, sometimes its 800/700 but 1k flat is an nice even number.

So i would say realistically $2k for the transplant, all the wiring up and cooler piping done, exhaust mated up.

2k would sound reasonable to me

There wouldnt be much in it if you sell of the RB25 (& loom etc) as it'll pay most the conversion cost i would imagine.

So outta pocket you might be a few hundred (plus RB26 purchase)

thats not bad..

are GTR front cuts plentiful?

thanks Nismoid

I couldnt tell you dude.

I paid near 4k (nearly 1.5yrs ago) for a complete RB26 with loom, included turbos/plenum etc etc.

So basically ready to rock and roll. Just needed to drop it in.

But then i rebuilt it, turbos etc etc. You know how it goes :)

So i reckon overall it would cost you maybe 5k at the most as i would imagine you could pickup a running RB26 with loom etc etc for less than what i paid, plus the re-sale of the RB25 (in stock form), if you have other bolton's to the RB25, sell them off separate and you stand to do the conversion even cheaper

why not attempt to do all the ins and outs by yourself and then just get a workshop to do the wiring?

x2

Its pretty easy to put an engine in......if you had a whole 1/2 cut it would be piss easy

also wiring isnt rocket science, you could get away with it for a 3 day weekend (if ur a noob at it) hire of an engine crane / stands or even just some tyres.

Day one remove RB25, take out rb26 and put in Rb26, start bolting shit up, ave a few beers

day 2 start wiring, possiably get running

day 3, finish wiring / tidy up, drive

I dare say it will all be plug and play as far as the looms go, IE plug for dash / fuel pump plugs / plugs in engine bay are same....But im more familiar with R31/32 looms, and R33 gtst, never played with r33 gtR

You are forgeting that the GTR has a front diff wacked in the center of the sump. It needs to be removed and the sump modified to suit the RWD layout. 3 day job its not.

Wiring a 26 into the same era GTS-T is not overly hard. Most of its straight forward much like a CA-SR conversion on a silvia.

Piping and so forth is not a bolt up and forget affair either. GTR uses a forward facing plenum the GTS-T does not, Air con lines are different if your concerned with that. Several things will come into it that are easily overlooked.

I am very interested in this. I originally bought the 33 cause I didn't want the complexity of a GTR drivetrain, but have always had plans to put an insane engine in. I dont see the point in putting bling boltons in there, just saving up for a big rebuild and enjoying the car as nissan intended atm.

I understand that this is basically going to involve putting a GTR front onto a GTST back. But done correctly and along with a bare metal respray and full rebuild of suspension I reckon that this be a winner. (So long as money is spent where it is due and work is carried out properly :))

What do u guys reckon? Do we have a winner?

The front diff does not pose a problem for an expirienced fabricator.

I only had to trial fit my motor twice before it was perfect (front diff removed) and it didnt cost anything extreme to have done.

The plenum isnt an issue, most people have a FMIC these days.

And i know (from my HR/RB26 conversion) its just a case of some shaving of the headlight surround to get the piping to the front of the car/cooler intake

We've lined it all up, and spent a lot of time looking at it, and provided you had the sump already complete.

I reckon i would be a 3-day job pretty easily if you had everything you needed there and didnt forget stuff.

The modding of the sump is they only real place i can see where you might get stuck, as thats where i did.

Other than that, i agree, its not a very difficult conversion like the CA-->SR :)

Also worth thinking about is the condition of the RB26.

You want it checked very well first.

Also the turbos, personally i would change them (and i did) as i dont really want a turbo letting go.

And lets face it, there is a mild chance of it letting go and things getting even more costly very quick

Well since most front cuts would be written off track s**ts I'd say its a given that it would need a full rebuild. Just need a :sorcerer: to give me some cash to get started.

Serious though I am pretty keen on this.

Lol watch this space!

i cleaned out my PM box as it was really full and deleted his PMs. :) sorry

i knw his name is Mark J. H

as it is the same as me Mark J. H he lives in perth or adelaide or somewher he has a white R33 GTST..

thats all i can help with sorry. good bloke. if u find him he should help out.

Noice! This is definitely becoming a project. I will make a thread when i'm ready to start building but I want to do a whole lot of research first.

I want to try and track down Mark to to get a few ideas for starters :)

i would definitly rebuild it, i wouldnt bother throwing an old motor in and hoping it will be ok. Same goes for the turbos. Are N1 turbo's considered an OEM item as far as the defect police are concerned? In SA ive heard of people having to 'prove' that their turbos are standard by running the numbers and checking they are factory nissan items. I think they may even be picky about garret replacements! very gay. but im sure there is a turbo option they will approve that will still give me 300+rwkw.

would be a very cool thing to do. Bloody hell these cars... i havent even finished the GTR and im thinking about spending MORE money on the GTS-t, a project that was supposedly "finished". They are NEVER finished are they guys..! :)

GT-SS are bolt on replacement, same as the Garrett equivs

They are the same housings as the stock turbos, so there is no chance other than pulling them off and measuring the wheels to workout whats on there.

The ID plate isnt the same, but if your really worried just remove it.

So is there anyone on the forums who has actually performed this conversion? I have my mad old race mechanic from when I was racing motorcross/enduros on board and he is keen to get stuck into the GTS as long as I keep it looking stock so its a sleeper :) He has performed mods such as a 500HP Ford Windsor into a 240Z with Nismo running gear so im guessing he is a little keen to get stuck in!

The conversion is pretty straight forward as Nismoid said.

The only thing that prevents it being an unbolt/bolt affair is the sump and some piping which is really not that hard.

I havent done one into an R33 but I have done a Z33 and R32. Its not really that difficult.

If your fabricator mate is handy then it should not take to long to get in and running/

    • 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.
