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

      Leak from Tokico BM50 Brake Master Cylinder

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
