Straight fit 350+bhp GT28RS in stock - £675

[bren]

We have a batch of special Garrett ball bearing GT28RSs in stock. These are a straight replacement for the original turbo and will run upto 350bhp.

Theyre sold outright so we dont need your original turbo back and theyre brand new units, not reconditioned.

They are just £675 :eek: :thumbs: :D

We also have loads of GT28Rs (330bhp, straight fit, £575 outright) and GT3071R WGs with both 0.86 and 0.64 turbine housings for £795. These have the sensibly sized 2.75" inlet rather than the larger sized 4" inlet which causes a ball ache in sorting piping from AFM to turbo :)

[Jez]

Are the RSs the 0.86 A/R turbine housing?

[bren]

Yep.

[Jez]

Cool - they'd go well with my S14/S14a stage 3 chip (when finished) :)

GT28RS's 350 bhp £675 or GT28R's £575 330 bhp

im takin it that u suspect the stage 3 to be more than 330bhp,but not more than 350 bhp thats y u say gt28RSs which is more expensive?

Not sure yet - all depends on what the engine on std compression can take. On a couple of CAs I've heard that the GT28R can struggle hold 1.2 bar to the red line.

[liquidsmoke]

does compression effect the turbo's ability to supply boost?

[Jez]

does compression effect the turbo's ability to supply boost?

No, it limits the amount of boost you can run before det becomes a problem, roughly speaking.

[zen200]

lets say that iv got gt28RS and stage 3 setup inc chip, if i wanna put thicker metal head gasket on can i just turn the boost up and run more power automaticlly? will ur chip compensate the extra fuelling?

[Jez]

To a certain extent it will, you would have to check for det and be sure that the fuelling is adequate.

Bren: Sorry for taking over your thread - I can start another one in my section if its a problem :)

[The_Judge]

What would you need to fit the RS to a S13 Bren?
Just wondering :D

[bren]

Inlet flange and oil feed pipe :)

[The_Judge]

Soooo... is it happy at 350bhp, or a bit stretched ?

Not got much cash, but your prices have come down so much recently
that a 300bhp car is almost viable.

I have been basing mods on Norris Design 330 spec, I know it's a real cheek :D , but from the parts you sell (rather than the Norris well expensive bits which I wouldn't buy) what are the costs involved getting to this?

I have a rebuilt standard engine, Volvo FMIC, uprated fuel pump, T25 (hybrid just failed, acuator knacked I think, spiked off the boost guage :( ), ND Stage 1 chip

So it would be:
uprated AFM
the RS
injectors
metal head gasket
engine / fuel management (chip or full blown emanage type thing?)
+ anything else you advise.

No promises, but I need to find a way !!!
(bonuses paid in May :D )

Any guidance much appreciated !!

Would a useful quick tuning guide sticky maybe?

Feel free to tell me to bug off if you think it's too cheeky :p :p

[bren]

uprated AFM 300ZX new ones are £239
the RS £675
injectors £359 for Nismo
metal head gasket £185 for Trust
engine / fuel management (chip or full blown emanage type thing?) Youd have to speak to Jez about a chip.

Management its a pain on the S13s, there no easy option at the moment :(

[The_Judge]

OK, thanks Bren. very very helpful as usual.

Do you cost up ND's conversions against your prices ?

BIG BIG difference :thumbs: :thumbs:

Jez, would you be able to comment on the management side of things if
you are still monitoring the thread ?

I could do a map for whatever setup you like :)
Trouble is one of my bit sof kit is knackered - just waiting for it to be fixed....

[nobby1973]

Hijack :wack:
Hi Brenmiester is the AFM with the housing or can you use the old one? Also if new will I need a different air filter :confused:
How much for the lot :whip:
Cheers as alwalys Nobby

[bren]

Have you been drinking? ;)

What do you mean is the AFM with the housing? :confused:

[king_j]

see when you say they can handle 350bhp how do you mean... what would the bhp of the engine effect the turbo [stupid tit filter off :wack:]

just wondering thats all.

[Vez]

Eh try that in english :wack: That makes NO sense AT ALL!

[TomM]

see when you say they can handle 350bhp how do you mean... what would the bhp of the engine effect the turbo [stupid tit filter off :wack:]
As in: they will flow enough air for 350bhp. :)

[king_j]

ok.... why cant anyone understand me tonight, it all makes sence when i read it :wack:

[paul]

The engine wont run 350bhp unless you have a bigger turbo to push more air in, or push the same air in but colder and freer flowing. So its the turbo that pushes more/better air that gives the power increase not the engine

[paul]

Question: Will I have to get a Z32 MAF for this or will it only be necessary if I start to push its limits?

[nobby1973]

Brenmiester I ain't taking enough drugs :wack:
What I was getting at is, all the Afm is a heated resistory thingy that screws into the aluminum housing at the top. Do you use the orginal aluminum housing and air filter or is it a complete new bit requiring a larger air filter :confused:

[DanS14]

For S14a you can keep and use the old air filter and original air flow meter as before.
If upgrading to a z32 AFM, this completely replaces the original AFM - easy swap over. The Apexi S14 filter does not bolt straight to the z32 afm so has to be replaced by a universal one or a 300zx apexi filter. ok?

P.S. Fitted my GT28RS today:)

[nobby1973]

Cheers dude :thumbs:

Yeah, because I work my ass off and have done for almost 8 years now! :D We get profit from parts, workshop, mapping and engine dyno hire, just none from Big Tone!!! Thorn in my side!! :ghey: :)

Anyway from what I hear on the grapevine you aren't doing badly yourself either Bren! :D :nod:

Cheers

Horse for courses, we are only so cheap because we are market led and the majority of our customers will import themselves if we dont work to minimum margins. Trust me, we dont operate on stack 'em high sell 'em cheap because we want to, we do so because we have to ;) That plus we dont fit, that also screws with prices as we can supply only.

Id love to sort a ND Evo ass kicking 200 but Im limited by my lack of spanner skills and so cant be blowing the fecker up all the time ;) LOL :D

Im going to be in touch once (when, if) our Tomei engine lands as it needs mapping on an engine dyno for road and race fuel and you've proven your abilities in safe high power engine mapping :)

[DanS14]

Hi bren, can you check the spec of the actuators supplied with the new GT28RS turbos please? Was expecting 14/15 psi (or an adjustable actuator like the previous other housing) gt28rs's supplied

cheers

[voodoo_melon]

I hear they're about 7psi, although mine's not fitted yet.

[bren]

Aye, I believe theyre a lot lower, around 6psi. Theyre low pressure because we got complaints of the previous actuators being too stiff. Cant win can I :rolleyes: ;) :p Just raise the boost with the AVCR :)

[DanS14]

That's what I was worried about, as my AVCR was on max duty to get 1.2 bar on the T28 at higher revs. Which is lower boost than I was hoping to run the RS at.
However it has been suggested that raising the start duty for all gears (to 30+%) may get round this....?
Are any of the stiffer actuators available?

[bren]

You can fit HKS etc actuators. See how you get on and Ill see if I can soruce cheaper uprated actuators :)

Or you could simply stick a couple of washers between the actuator and bracket. This will increase the preload (same as shortening the arm on an adjustable actuator) and raise the boost. Easy and dirt cheap :)

[DanS14]

Cheers Bren :)

[paul]

Or you could simply stick a couple of washers between the actuator and bracket. You've been hanging around them S13 boys again, havent you ;)



Right, me thinks the time has come. The wisps of smoke from the exhaust are getting more frequent.
If you still have a GT28RS left mark it with my name :)
I already have one of your manifolds and a dump pipe. I will need all the studs and nuts to do a swap and gaskets.
Do I need an actuator? If so, one of those too (Adjustable)
How does it connect to the intake pipework?

Oh and while you're at it, chuck me in some Nismo 550 injectors, please :)

PM me the price just so I know what to expect please :(

[MiRo]

Are the GT28R rated at 330 bhp bolt on? GT28Rs? I'm curious because I was wondering if there would be any possibility of running my standard AFM with any of these two turbos? At which revs does the boost come on both of them?

[street]

Bren can you get the rs's with the wide inlet mouth :)

[bren]

Yeah if you want but youre wasting your money and opening yourself up to a load of un-necessary additional ball ache :)

You wont get 400bhp out of one either if thats what youre aiming for :no:

[street]

Its just ive got rid of a 71r and everything was fitted round that.need to change me sig as ive had to start all over again after a bit of a bump and a sore engine :( :)

[bren]

Ah :(

The RS are available with the same size inlet as the 71R :)

[ade76]

are these still in stock?

[bren]

Yeah, theyre not £675 anymore though, the suppliers humped the price up. Theyre £775 now :(

[ade76]

what about the gt28r?

[bren]

£575 and in stock.

[ade76]

how much better are they than the std t28?

[Butuz]

spool earlier and can handle 30-60bhp more power dpoeending how far you want to push it :)

(and frankly, i'd push it as i wouldnt really need a new turbo to last 100k miles, id rather have the extra boost for 25k :thumbs:

Butuz

[bren]

They wont run any more power than the standard T28, theyre essentially the same turbo but the GT28R has a ball bearing core so is better equipped to handle sustained high boost and itll spool up faster. I wouldnt fit one to an S14 unless your turbos knackered, not worth the money in my opinion.

The GT28RS is, the GT28R isnt.
