Qs on turbo

[Advan_01]

Hi Guys, I'm wondering if anybody here could give me some feedback on this turbo I'm looking at e.g Will it be laggy? enough to support up to 240rwkw @ 1bar? and etc. Seller wants $700 for it, is this a good buy? Help is much appreciated. Thanx.

Specs: The turbo has a internal wastgate with .60ar front housing with 54mm wheel and .48 exhaust housing it has a 3 inch inlet and is rated at 400 HP the turbo is like new with new ball bearings,wheels and housings.

dont use this turbo unless you want a boat anchor. is it a ZY turbo? i had one of these on my car for a week and the wheel rubbed the housing also NO POWER AT ALL. stay away from it... GCG turbos told me 80% of these turbos fail within the first 3monts of use.

Its a garett turbo. Thanx for your advise.

What engine is this for ?

If you have a RB25:

The turbo should surport 400hp but you will be pushing it to its limit's and you'll hvae to run more than 1 bar of boost to reach your target.

Spooling should be fairly quick, but it will hit boost hard when it comes on. makes sure you have all the surpoting systems to go with teh turbo, eg: Fuel pump, Injectors, ecu, the usual exhaust and front mount etc.

I personaly would go with the HKS 2835 as this is know to be the best overal turbo for the RB25: Quick spooling and the ability to reach 300kw's.

I'm currently running a 700 horsepower garrett turbo on my RB25 with .70 comp and .82 ex a/r. And it spools at about 3100rpm and is on full boost by about 4700rpm.

Hope that helps,

Yes I have a RB25. I have almost everything except for injectors before turbo upgrade. To pull about 230-240rwkw is that possible to use my stock injectors and get a fuel pressure regulator instead?

[55Nat]

Yes you can use your standard injectors, and yes you'll have to install a fuel pressure regulator.

R33 Injector size.

GTST Side Feed High Impedence - 370cc = 250kw's - With FPR

GTR Top Feed Low Impedence - 444cc = 280kw's - With FPR

But to achieve this you'll need to get your injectos cleaned as most older RB25 injectors can be clogged. So get them cleaned otherwise get a set of Sard 550cc injectors.

Also which ecu are you using ?

I'm using S-AFC2. Pulling about 190rwkw @ 0.9bar

[55Nat]

Ok,

So your using the stock ecu right ? You'll need to upgrade that to be able to reach 240kw's safely as the standard ecu will play funny buggers with your car after around 200kw's.

My Reccomendation would be to sell the safc ll and buy a Apexi Power FC ecu as then you can control the fuel and the ignition and make sure its tuned safely. You Don't want to melt your pistons.

But for now the safc will do fine intil you can afford a tunable ecu.

Let me know how it goes.

So u r saying I can change my turbo now using SAFC for the time being and maybe get a Power FC later on? When I get Power FC I will not need the FPR anymore or it has to be there as long as I'm using stock injectors?

[55Nat]

Yes you can use the turbo with the SAFC ll intil you can get a Power FC but dont go boosting it too much over 10psi.

With standard injectors you will ned a fpr to keep them at max pefrormance with more pressure in the fuel rail. Other wise they will run at stanadard fuel pressure and you wont be able to reach your target of 240kw's.

But when if you get aftermarket Injectors you can still use the FPR but you dont have to as you wont need to be maxing them out to get 240kw's.

All a FPR does is increase the pressure in the fuel rail to 3kg/m as standard is 2.55kg/m which ables you to get your inhjectors to their max.

hope that helps,

Thanx for ur advices and they are of great help. Wat aftermarket FPR would you recommand at reasonable price?

[55Nat]

I'm about to install a Malpassi fuel regulator onto my car.

I picked it up for $280

You can get 2 types:

1psi Rising rate fpr

or

2psi Rising rate fpr - I have this one as im going to be running high boost levels.

The difference between the two is that when under heavy load (boost) it will rise your fuel pressure into your rail from standard 38psi by 1psi or 2 psi as boost increases.

If your after a Malpassi one I can sorce you one.

A friend of mine had one of those. When he brought his car to a tuner, the moment the tuner saw it, he says that has to go before anything can be done. He says that is no good.... dont ask me why...i dont know either .. thats wat i heard.

[55Nat]

I've herd they work fine.

But i will find out more info when I install mine for final tuning stage.

I will post if the fpr works or not with power read outs and a short video of the dyno run.

(this may be couple months away though.)
