No it's not

> The turbo is free btw....What are the pros and cons

Possiblity of:

- Different fuel pump

- Different manifold (no direct bolt on I dont think)

- Different ECU (Car Computer)

- Install intercooler (factory one is ok)

- Brake Upgrade

Albet the 33 GTS is a fine tuned N/A car its not feasible for direct bolt on. Much better to sell and get a stock GTST. Cuts out the hassles of ECU, Fuel maps/sensors etc which can affected as soon as you Turbocharge it.

> after affects of performance etc

Higher fuel usage. Faster acceleration. Induction sound. BOV sound.

Much higher kw at the flywheel and wheels. GTST stock is 187 at the flywheel, I think the R33 N/A is around 90kw at the flywheel.

My Advice, drive a friends GTST and then go buy one :P

Seriously, you can spend $5k to turbo yours properly and it wont have the same resale value as GTST as its been converted

Same argument VL N/A upgrade to VL Turbo.

Other things different between the two models:

-N/A brakes are TERRIBLE and not SAFE for Turbo conversion (well the VL ones aren't)

-N/A ECU would be shit as (the rb30 n/a ECU that is)

In the "turbo" forums people ask the similar question:

> Should I go the RB26 upgrade for my GTST?

The short answer is no unless you want something specific. Some people think if you get a GTST and swap engine for an RB26 that its worth almost as much as a GTR. Theres many more features in the GTR that yours wont have. Brakes/ECU/Fuelpump/Intercooler etc are some of them. If you wanna just wanna run two turbos then no. If you wanna stroke it, cams, pistons, ecu, apexi powerfc, single high mount turbo etc.... and u want 800bhp then yes RB26, else no as you'll have hardcore traction problems.

Hope this helps a little. Bu all means get some quotes but youll probably find its not worth it as it wont have a much higher resale value as its still a GTS

Guys I was just wondering whether it is worth putting a factory turbo on my GTS R33? The turbo is free btw....What are the pros and cons....after affects of performance etc? Ta.

i agree with paulr33. its either you get a new front cut and do your conversion from there or dun even bother at all. at the end of the day, the cost and hassle is too much work... a conversion is still highly recommended than a bolt-on UNLESS your internals are already built for it... such as the NA supras that came with forge pistons already ...

Haha sorry for the low figures. I realise my estimate was way out :P All in all it is probably better and cheaper and more cost effective in regards to economy of scale to sell yours and a GTST instead. But each to their own

Some prefer to do the upgrade themselves (from N/A to T) and learn along the way etc. Just remember its not a simple as bolt on turbo, start engine and your off. There are lots of other factors to be done as metioned above.

If your going to do, do it properly (this is where the main cost comes from) and upgrade everything else as you will need it

Im pretty sure, not 100%. I know all the fuel maps and airflow ratings will change as your engine is use to say x amount of air flow and it will now get say x + 300 of airflow. Could even max out your stock airflow meter. Not sure if they are different between N/A and T

Also engine compression could be a problem as rb25de and rb25det have different compression levels

meaing when you bolt on your T it could be affect the engine and youll be restricted to a low boost level, like 6psi max.

Ask in the forced induction forum about ecu change if you bolt on a on turbo to rb25de

      That's the thing....the basics of fuel and ignition are deceptively simple.....getting it to behave like factory in all conditions after airflow mods is way more complex. Newer cars like the V37 are all about modifying the standard ECU which is about a billion times more complex than they were 20 years ago, with a bunch of parameters affecting others

      The larger TB I had on the SS was a pain to get to idle right, but, that was cable In the end they just raised the idle up a couple of hundred RPM so it was happy idling away either in gear or in park (slush box life) I'm curious on how my NC will idle with the new intake, larger TB, and cams that are currently going in/on, but I have faith that MX5 Mania will sort this "electronical" "black magic" out the best they can in the tune with a electronic TB Sometimes I wish I knew more about the intricacies of tuning, but most of the time I don't because I know it would hurt my brain 🤣

      That's the thing. Cam is smaller than before.. though the old cam was +6 degrees advanced. We're talking huge changes here, the narrowbands want to trim out 20% of fuel and pull the (wideband) idle to like 16.0 AFR or such. One side is a little more trimmy than the other. Think along the lines of ~20% to ~15-18%. Unfortunately my scouring of the internet hasn't really found anyone with this issue. People either just disable NB's or have them wildly different, where one is -20% and the other is +20 or 0 (i.e a sensor is just dead/wiring is just busted). Turning them off and relying on the base map only results in the wideband reporting at about 14.0 with the Varex closed. It'd be a little leaner (closer to 14.7ish) with the Varex open. I know I can just change the switch points so that the narrowbands agree with the wideband, but it's still odd. Both of them are reading voltage, it's just that they're reading quite high mv, in the ~800 region. It's just odd. This was with the IAT fudged to report it was about ~22 degrees which is my guesstimation of the temperature in the room. I have an OEM sensor ready to try tonight, which is slow and crap - but .. worked last time I used it. Sadly I am aware that idle tuning with the big TB is going to be a PITA and I look 'forward' to many hours spent stalling or stumbling idle or delving into drivability things.

      Probably the cam.

      The GTR strut brace clears the new manifold.. by about 0.5mm. So this means I need to buy an OEM GTT Strut brace (again), which will clear the new manifold, but not the bonnet vents. I guess I can sell the GTR Strut brace with the bonnet with the vents as a package deal as someone will need this one day. So my choices are vented bonnet but no strut brace, or GTR Bonnet with OEM brace (which I have to buy) but is bright red instead of the same colour as the rest of the car, which means the entire front end of the car will just be red until it goes back to paint jail. In other news the engine starts and doesn't leak. Why both O2 narrowband sensors think the tune is rich AF I do not know. The idle is also pretty shitty and my expensive IAT sensor from the USA is dead. The car sounds awful. But I assume or at least hope this is due to the many exhaust leaks, and the concrete garage it is in, sitting there with 0 intake bolted to it, and no bonnet or panels or anything to stop the induction/intake sound which is about 200db.
