Is It Possible To Do A Turbo "upgrade" For A Gts-T Over The Stock On The Cheap?

[sadr33]

I'm looking at changing my R33 gtst Turbo soon (mine is sounding whiny). I figure while I'm at it I can try to get something better than stock turbo but I doubt it is possible on very tight budget?

What are my options, If prefer to keep it close to $500. The Cheaper the better. If an upgrade is not possible I'll settle for a similarly performing replacement unit

There are a few $200-$400 dollar turbos online that suit rb25.

But I'm a little confused how aftermarket turbos compare to a stock one.

I see a lot of turbos saying they are rated up to 430hp etc or 550hp but they dont all tell you how much PSI they can handle safely

I know 10psi is the safe limit for a stock turbo but how does it compare to some cheap ebay turbos?

Has anyone had any experience with this one?

$500 is not possible. Ebay is not possible - actually Ebay is possible, as long as you don't expect for $400 paperweight to late more than 15mins.

You need:

1. ECU / Tune

2. AFM

3. Injectors

4. Exhaust/dump pipe

5. Hypergear turbo

All of that add's up to well over $500. In fact it adds up to $4,200 if you by some stroke of luck have no other issues and shop around... Which is unlikely with a 150yo car, so allow $5,200 as a starting point for a turbo (+supporting mods).

Look for a 2nd hand hiflow in the for sale section.

Ebay ones are all I can afford. I have heard some of them last fine if not thrashed, I am not planning on being too harsh on the replacement turbo. Ill be happy if it can handle 10psi.

But since you mention all those upgrades. Yup I realise there are MANY things to upgrade before you upgrade the turbo normally. But since I'm in need of a a new turbo it changed my priority. And isn't worst case scenario if you fit a better turbo without all those upgrades slightly less power down low and more lag?

I'm ok with that in the meantime.

Only Current mods are 2 stage electronic boost controller.

255lph fuel pump

Nismo FUel pressure regulator

Yellow jacket coils with Bcpr6es.

I haven't really experienced knocking or fuel cut. I don't think I am running rich or lean. So if I haven't hit a limit on these I dont see the point of upgrading them for low boost applications especially since I need a new turbo first.

Ill have a look around. I had a look at some high flow prices they seem to be about 1.5k. Wouldn't mind a second hand turbo off somoene who is upgrading but id prefer to hear it running in a car first otherwise what guarantee do you have it wont be blown?

At least with an ebay turbo you have a 1 year warranty, or so it says.

Anyway, I know many sau members hate ebay turbos but humor me and tell me how much modification do you need to fit a non standard turbo such as a kkr480 into a r33 gts

For example this

Your best bet (and only bet really on your budget) is to get a replacement stocker from someone who is upgrading. You should have put the money for the electronic boost controller and Nismo fpr in a savings account towards an upgrade (neither is making your car faster).

[LANDSCRIBBLE]

The custom dump pipe that would need to be fabricated by a workshop costs about as much as that turbo!

[GTScotT]

You will not be able to run anything but a stock turbo unless you tune it.

the bare bones minimum will be about 1700. That will include sending your stock turbo to hypergear and getting it highflowed, then having your ecu remapped by toshi.

with that you will be lucky to scrape in at 200-220kw. If u want more u will need the rest of the bells and whistles.

No remap = blown motor.

Your choice. Whack on an eBay turbo and watch it all blow up in your face or actually face the music with the commitment you made buying a 20yo performance car.

I'd be leaving it all alone until you can afford more then a "ebay turbo" Even then, like the others stated above. You'll find alot more problems once you start changing things over that you didn't account for.

$5k can turn into $25 very quickly....... Trust me.

[GTScotT]

^ Exactly.

$450 forged pistons = $3,500 mostly assembled motor (me - almost there now).

$900 turbo upgrade = $5,000 running on the car (all of us at some point).

It's never what it seems, and you should ALWAYS put pen to paper before you do ANYTHING.

I've seen some stock upgrade turbos on eBay from a shop in NSW, 2 year warranty, 100% positive feed back, they're $400 just a stock stronger highflow turbo. They seem alright and everyone has been giving them good feedback just saying I don't think a cheap turbo is IMPOSSIBLE is all

Yes, it is possible to buy a cheap turbo. No one is disputing that. It's the other costs associated with correctly running the turbo without the engine going bang that turn it into an expensive excercise. (tune, ecu, injectors, labor etc)

Get a Ebay turbo!! Bought it for $450.. all plug and play.. had it for 2 solid years running around 16 psi..

[040122]

On the extras topic, does the car need to be tuned just to run a high flow on the same boost as stock?

Id be doing a tune for any major change to the engine, Fuel, air components of the car. So yes.

[AngryRB]

on the cheap this is what id do, buy secondhand gt30 and get a turbo shop make it fit into your exhaust housing,

then get a safc and have it tuned upto 200ish kw or just checked on dyno for safety, run it on about 6-7psi

turbo $800 plus $200 for machining

dyno check $200?

then later safc $300 and maybe find a wiring diagram or google how to fit it and tune it for $600 to get 240kw??

boost is not relative.

new turbo = tune.

[D.I.Y. Mik]

I have a bigger turbo and stock injectors and ecu tune.

I cant turn the boost up or it starts missing. Not good for the motor.

At the very least you need a retune to make it run safe.

A safe tune without supporting mods is much less power than you could have.

reminds me of a group i used to be an admin of- "All that money on your car and my stock bike is still faster"

I love my modified skyline but f*k me, get on a jap superbike and all relevance of 4 wheels becomes distant (except for safety)
