easier and cheaper to buy a gtst than convert a gts, you'll have to change the brakes/wheel hubs to 5 stud, which also means new wheels etc... and get it engineered, and i think most people just swap the whole engine for a gtst one rather than mess around with the N/A one, so probably not as cheap as you imagined.

you don't need to change the wheels/brakes etc etc etc

easiest way:

manifold

turbo

intercooler (optional)

injectors (optional)

fuel pump (optional)

BOV (optional)

electronic boost control

boost gauge

other shit i left out :D

all you do is change the manifold, put turbo on, get lines etc etc done, add other shit if you want like FMIC. Set bosot to ~7 PSI max - as your compression will still be too high to run high boost....

if you want to go all out engine swap RB25DE for DET - half cuts cost few grand, but keep in mind GTS gearboxes are weaker - so you'd need to do the lot if you wanted to run 15+ PSI and expect your vehicle to last :D

cheaper to buy one in the first place - but not as fun :D

i dunno i reckon an rb30 bottom end conversion would be tops as for it, as the gts n/a would be cheap as to get and you can get the rb30 block for like $300. then do a 25/30 conversion on it, 3.0 block 2.5 twin cam head with turbo manifold would be a monster the rb30 howto even says to use the n/a 2.5 head and change the brakes

i wouldnt keep stock r33 gtst brakes on an rb30 conversion so it doesnt apply you could just get slotted and drilled rotors from dba (dba4000) and youll have to upgrade clutch and other shit if you did it in a gtst anyway so its no diff really, just a cheaper base car. the stock gtst clutch/brakes/cooler wont take the torque of the rb30, well it well just very badly and not wise. rb30 gt340 highmount it would be an absolute killer i think the stock rb30 with the r33 turbo winds up boost from like 1300rpm or something stupid, whereas stock r33 gtst hits 7psi at about 2500rpm (well mine does) or just a tiny bit over 2600rpm maybe

something to consider

rb30 should set you back around 4-5k ? check out the rb30 howto

you already asked this in the forced induction area. i believe the na head will fit but it has different injectors and head gasket, it will work you wont be able to go over 5-7psi safely as the compression is different between the turbo and na head. to run 12psi youll need to change injecotors and gasket to change compression ratio as far as i can recall there was a better answerr in the forced induction area

    • Bump on this to not make another post, had a ‘head drain’ leak on me and have the engine out as we speak. Planning on just putting a new freeze plug back in , plug the tapped holes and just be done with that headache.    Now I still want to relieve pressure to allow oil to pass down the blocks returns easier. I’ve seen catch cans with multiple vents help folks with this issue on this forum.  I’m wanting to make my own. I have some pictures here of my setup if anyone can help how I should plumb and design the catch can I would deeply appreciate it !   rb25 Oil upgrades: 1.0mm restrictor n1 pump/billet gears extended crank collar  extended sump with trap doors/w welded fitting    
    • The Frenchy's kit is the way to go forward. A modern compressor that weighs about 1/2 as much, is at least twice as efficient, and will do a good job on R134a. And of course the kit has everything else you need to connect it up and have it work properly.
    • Hey all , I am in the process of having the AC system in my r32 GTST converted from r12 to r134a and I’m being told my compressor has gone bad and I will need a new one. I was wondering if anybody has any suggestions for what is the best route to go aside from dropping $1500 on a new oem one? I did see that Frenchy’s performance garage offers a kit to mount a Toyota compressor, has anybody actually used this kit on their car? Or is there anywhere I could purchase just a clutch? Any help is appreciated.
    • Well, your RB20 ECU loom won't have wires for the boost solenoid, that boost sensor, and possibly one or two other things. There could be differences in seemingly random things like the charcoal canister purge solenoid, because the 25DET has to handle boost in the vacuum system and the 20DE does not. I don't know - I haven't looked. It is very likely that all the most important things are same-same, being the main sensors like AFM, CAS, etc, and the injectors and ignition. Not that you'll need the AFM for the Haltech anyway. I would suggest that you would seriously want to sit down with the pinouts for both ECUs and just go through them and highlight green what is the same, orange what is different/missing, and make a plan from there. It's not going to be difficult. It will either be the same or need to be fixed.
    • yeaaa that's why I haven't done any wiring to the stock ecu harness because I have the haltech, but then that leads me to the other question of "is the pnp harness really plug and play?" or would I have to still switch some pins/wires over because the pnp is for the rb25det neo harness, and not for the rb20de neo harness. was really hoping to find something to spoon feed me since so many people have done rb20neo + t conversions, but man this is rough.
