Hi I just recently purchased a r33gtr and looking to get it tuned on 98 as I don’t want to go e85 I was hoping for 380kw atw on 98 do you guys thing it’s reliable to achieve this power with these old turbos mod list below

Starting with r33 block, r33 crank with n1 oil pump, eagle rods,wiseco pistons, arp main studs,acl race bearings, tomei 260 deg pon cams, cometic head gasket.

Trust t517z turbos wiyh trust hard pipe kit

Trust race intercooler, hks dump pipes and 3in exhaust

R33 twin synchro box with twin plate clutch.

Sard fuel pump with 720cc injectors and billet fuel rail, Sard fuel pressure reg

Brake vacuum chamber

For reference, back in 2011 my 33 gtr with a built motor, good head t51r, full fuel system 1000cc injectors, and everything that should go with it was making 422kw on 20psi with 98

before going the full fuel system with surge tank and extra pump and to 4” exhaust, I think we maxed out out at 401 from memory.

Best bet would be to look through the dyno section for something with similar mods to you to get a reference of what to expect.

the end of the day a dyno is just numbers that can be fudged either way. True test of power is 1/4 mile

Immediately just lose the turbo timer so it doesn't give you problems one day. For the rest just try to track down a good tuner and post up the results!

Hang on, so does the car already have that list? Or is that to purchase?

 

No sane person would buy a power fc new nor those injectors considering the substantially better options available now. . If you already have them it's a different story.

 

 

And as above lose the turbo timer.

Haha yeh wow. Genuinely had to check if this post was from 2003 ?

 

OP, if your car already has those mods then just get the car tuned and be happy with where it ends up knowing that there is plenty of money to be wasted in the future chasing more.

Why get rid of the turbo timer? I thought they were a good thing for turbo engines to let them sit for a bit after driving before shutting off the engine.

And this is something that you cannot do for yourself? After all, it only needs doing if the car has been working the turbo a bit hard in the last couple of minutes before stopping. It hardly needs to be run to cool down on about 95% of stops.

@Berksgtr It'll get close to 400 rwkw or 380ish awkw on 98. T517 is rated closely to -5s. Unopened 26s have hit that target. It'll just be a tad laggy by todays standards. Will still be good. Gotta start somewhere! Congrats on the car :)

fair enough sure, but why get rid of the timer if he's already got it? The other post sounded like the timer itself would cause an issue.

Can attest to the shittness of turbo timers, I had one in the Skyline as a young pup. Caused all sorts of issues from not starting, to not switching off when the countdown reached 0, to being a parasitic drain on the battery, etc. Even after pulling it out, the loom has been hacked into, there's no making that reliable again. Its one of the reasons I undertook a complete rewire of my car.

 

Stupid things. Feel embarrassed to have had one. As GTSBoy says, try to think of the last time you boosted your car hard and then switched the engine off. It just doesn't happen, there is always 1 or 2 minutes of sedate driving before you park up that is far more effective than 30 seconds of idling. Superbly ricer modification.

    • Appreciate the feedback. It is street car, but not a daily. Last week I got a quote from a good exhaust shop for a decat, one which is bolt-on, bolt-off to be easily replaceable. I got quoted for around €150. I usually do push the motor, but I wasn't in this case to make sure that no damage is done until I get the cat sorted. I think it's best to also ask the exhaust shop for the other option and see what they can do. If (big if) I were to decat though, would it be best to tune the car or would the stock ECU handle it? As far as I know, the stock ECU is not tunable and that would require additional purchases.
    • As above, definitely bash it or get it replaced with a high flow unit.
    • get some flares on them, or wider guards haha
    • Another question sorry, what stainless do u use in the turbo external WG plumb back piping? Is it 321, 316 or 304?
    • Right, its been a while for updating this car, but I made some small but important progress today. In the end I bought an Ecutek dongle from the Australian distributor Tunehouse (for local hardware support) but have gone with a remote tune from Racebox in the US (because they have done millions of these, and I could not find any tuner where I could access the tune anyway as they are all password locked). The App is reasonably easy to work with, but the PC software reminds me of Haltech's ECU Manager that you need to use with the Plat Pro ECUs, it is a nightmare.  Anyway, I sent the details over, got back a tune file and a request for data logs. I finally got a chance to access a private test track today as they want redline logs in 3rd and 4th, and have sent them back for the first round of reviews. The main difference in the tune is going from 1.0 (stock) to 1.3 bar (19psi), although I'm sure is a lot of other stuff in the background. Keeping in mind this is a dead stock car with 125,000klm, this is what the App's performance test claimed: Before After Interesting to note that both 400m tests had the same terminal speed (158klm/h) but different ETs. And no, the speed limiter seems to be higher than that at 186kl/h. Summary of the key logged parameters for the 3rd and 4th gear runs were: Those little turbos were certainly whizzing at 200,000rpm+.  Also I'm really not that excited about oil pressure 55psi at redline so I think I'll go thicker than 5w30 (nissan recommend 0w20....) and see if that improves it. Other than that (and the big boost spike....) everything looks good as a start to me.
