Chaging stock cermaic turbos

[ab20000]

Okay so I'm new on here and haven't yet bought a skyline and some of those I am looking at still have the stock ceramic turbos. What are the options and rough costs around rebuilding them or is it better to buy used steel ones? Are there other bolt on options that are better spec?

[MrGT]

For bolt on goodness i would buy a set of the new tomei turbos that have just come out rated to 600bhp (about £2000)
Or you could bolt on some 2860-5's (about £1400)

But both would require spring mods ie injectors, fuel pump, ecu ect

All this has been covered before, try a search on the forum other than that google is your friend.

Don't need 600bhp, well not yet anyway. What can stock injectors and pump take?

[dan-hipgrave]

Stock fuelling/airflow system is good for ~450fwbhp.

A set of 2860-7's or N1 turbos, and a remap and you'll be sorted.

I would steer clear of rebuilt steel internal turbos if your budget allows.

450 sounds plenty to me considering first skyline, will take a look at these turbos for price.

Assume the r33 GTR and r33 GTR v-spec had the same turbos? Are the R34 turbos better in terms of power and quality?

Cheers!

[dan-hipgrave]

Yeh, 33 and 33 v had the same turbos.

Forgot to say about r34 turbos - they too provide a cheap upgrade, but aren't as good as the others mentioned. If you're only after a small power increase then they are a good shout for you.

To save me starting a new thread for a similar question:

I have standard ceramics too, I'm thinking of replacing those with either 2860 -5's or -7's. With my wedding in 8 months, I can't afford to do the injectors, fuel pump, etc. yet too, but I'm not looking to run any more power until I can get everything else sorted anyway. I want to get my intermittent over boosting issue sorted too, and am thinking of booking the car in with Ron, so getting the turbos done at the same time would be good.

The car is already mapped for 1 bar (Apexi PFC), so I think I'd only need a tweak on the mapping front. Is there anything else I need to consider? Any thoughts / advice would be appreciated.

[GTR Cook]

My adivice would be, if your looking to change turbo's, only do it once so save a little extra and do the supporting mods. Try and think where you want the car in a few years time and not in the next 12 months.

450 will seem plenty in the time being but you will get used to it!

Just had 2860-5s fitted and lover them!

[Red Duke]

Thanks Cook

I've already got ~430bhp (360atw) and I'd like 500-600 tops, without needing to go down the route of a rebuild just yet. I'm just after the relative security of newer turbos, I know I'm not pushing mine, but there is always that doubt of "they're ceramics" in the back of my mind. I thought it'd be a worthwhile upgrade, especially if the over boost issue is being caused by something sticking, or not releasing the pressure as it should.

I guess I could wait until afterwards, and just buy a couple of bits now and then, cuminating in getting Ron to get the turbos for me after the wedding, and then getting everything fitted and mapped, but I'm an impatient bastard.

Besides, I've been doing OT at work, and getting a bonus for the Olympics, so I'll be damned if that lot is getting sucked into my wedding savings too!

[GTR Cook]

My reason for change was because my rear turbo exhaust wheel broke during a track day, so they do break.

I went for the -5s so that I could go for more power in the future. They will run fine on a standard engine with slightly increased lag and the other bits can be done at a later date. Just do everything you need to in that area at once and most important is the map.

[purleskyline]

I went from standard ceramics to garratt gt2860-5s,totally standard just a power fc ecu. 478 fwhp.

[Red Duke]

Mmmm

Thanks chaps, definitely going to have a think about the -5's, not long until payday, so I'll have to syphon a few quid off to go towards the Garretts me thinks...

[Rookemonster]

I had ceramics too, car was tuned to 357 ATW last year with a LinkG4 ECU.

This year had tubbies converted to Hybrid plus injectors, fuel pump, tomie poncams, now makes 450 ATW, massive difference, really pleased.

my goal was 500 at the fly without internal mods and minimum lag,
so for me Hybrids were the way forward, why spend the cash if you don't need to.

[ab20000]

Some good info on here. Newbie question but assume when you say hybrid turbos you just mean different internals? (so in this case steel internals)

[samgtr]

What about HKS gtss turbos?? I was told there very good for quick spool up and good for 500hp

Thats what i have lined up for mine
