I got a r33 gts............

I'll be buying a rb25det engine off justjap auto and putting it in my car......will it be a direct conversion...or are there any other things to change???

please advise me...

Well the reason I said that was because when I was looking at doing it the engine package was $6-$7K...they're a lot more reasonable now..but it's still going to be at elast $2K to put it in.

The best option is to make an RB30DET out of your N/A engine

Great thread,

I too made the same mistake, that is buying a N/A skyline except mine is and R33 GTS. I am desparate to turbo my engine, however my local mechanic has told me that you cannot turbo the N/A....that is without ruining the engine! Reading this discussion has helped me see what can be done to the engine, with a low cost outlay and surprising gains, Thank you!

However I have a couple of questions,

How does the car now drive?

Is it as reliable as the N/A?

Are you sure that the modifications will not damage your engine?

cannot wait to get my project Turbo underway. :flamed: :flamed:

DanielWilliam: The car currently pulls harder than a stock GTS..this is with the crappy N/A exhaust still in place and running 6.5psi that is probably down to the higher compression :(

I've had the turbo on my car for about 50,000Ks now and nothing has been damaged in that time, from a reliability point of view I think that's great. If the tune is good, you should have no problems...just don't expect to be able to cram 14psi in and you'll be fine.

Great to here that Dan,

It has put to rest the only real concern I had after reading the thread (the longterm future of the engine).

Sounds like the car goes real hard compared to the N/A You had and I have now, mine came with a full Trust exhaust out of Japan which will hopefully complement the turbo well. All I have to do now is get the funds together now and I can start the project.

I guess it is like you said tuning is the difference the car will run well and hard with some dollars in the tuning side of the car!

I will keep you informed to how my conversion comes along. I have some pics of the car in its current state in my gallery.

Cheers mate

If anyone is interested I have everything you need to do this swap

Off an RB25DET

Exhaust manifold

Turbo (No play)

Oil/Water lines

std dump pipe

Inlet manifold/Plenum

Fuel Rail and injectors

If anyone is interested in these PM me and i can send you pics

reason why i am getting rid of them, upgraded to GReddy plenum and getting top mount turbo setup

That list could make my shopping very easy!

That stuff is exactly what I am shopping for at the moment, what sort of condition is the lot in? whats your location in relation to Newcastle? Also with the condition of the parts in mind what is your best price?

Cheers :P

    • 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.
