Im getting injectors the same time as the turbo as they are maxed out now.

Will i need the Z32 afm or will it be ok?

Would it be wise to get an aftermarket exhaust manifold? if so top mount or low mount?

Will the set up i have reach around the 250kw atw.

Yes you'll need the Z32 afm. It'll be maxed out once u hit above 200rwkw for your car.

Not a must to get an aftermarket exhaust manifold.

Top mount turbos are defectable, so go figure :P

So you're giving tech advice now? Hahaha...

330hp is nice, hows your response from stock? Are you as happy as me?

Happy as a pig in shit !

The Hitman (Matt) was very pleased with it's behaviour. He reckons it was spooling like a new turbo and he's seen a few i'm sure.

Response compared to stock turbo is a tad lagier but very close.

But then again it's got another 10psi to spool before hitting the max :D

Nice smooth delivery of power and lots of it.

Anymore power and i'm into a telegraph pole for sure.

So many huge figures are flying around at the moment but for a daily driven R33, i wouldn't want anymore lag...or power.

Absolutely love it

how would the hks 2535 compare to slides hiflow? (without the vg 30 rear).

cause im about to retune my car with the slide hiflow

No idea, get it tuned and throw up some results.

I'm predicting over 250 for you with slightly more lag.

(just guessing mind you)

Birnie - been interested in how yours is going with the new clutch. So its all you'd want - thats what Im hoping for.

Im using a GCG with VG30 rear housing so hoping for similar result.

The lag isnt too bad?

Does it spin all the way through 2nd? I might have to get bigger tyres than 205s hahaha

lol @ guy who said gtrs with these turbos dont make 300rwkw lolol

dude.. with a pair of smaller hks 2530's u can crack the 330awkw mark.. these babies will more than flow enough for 350awkw.. stock gtr turbos r good enough for around 230-260awkw

as for a rb25.. i personally think the turbo is too small as a single unit... its only 100cc smaller than an rb26 and theres no way in the world id run 1 gt2535 on my car.. it'd choke to death.. response would be awesome.. but id be so down on power... a GT30 runs perfect on a 2lt sr20.. and i can only imagine how much a better match it would be for an RB25

ive got plenty experiance with turbos and engines and id definately be gettin a GT30 for an RB25... with a .86 rear end :D

The new clutch is a button/cushion job. Only about 1 month old. I'm SURE it;s slipping in 4th and it's starting to annnoy me

Are there any adjustments you can make to clutches to make em bite harder without removing them?

How can it be slipping already ! And i haven't been treating it bad. The old commuting with a WOT every now and then.

But i was suspicious of slipping the day after it was fitted.

The lag is nothing really.

I'm not on the North Shore for work anymore.

Send me a PM if you want to meet up somewhere (seeing you have been keeping up with my progress :worship: )

Spins in 2nd but not too bad...i have 255's on the back though so that probably helps but the power deliver is nice and smooth, it's not a freegan bang! It's a woooooooaaaahhhhhh !!! hehe

205's !! :thumbsup:

Finally, some really good results for the 2535. Now I'm going to have to decide between the GTRS and the 2535.

Are the S15 injectors a direct fit??

Just remember you can only get the 2535 2nd hand so that does carry it's risks.

But, there is no doubt the GT-RS is the far superior turbo in every way, just more expensive.

S15's are a DEFINATE direct fit.

Put them in myself and it was easy as....

great work birnie!!

Thanks Moonus,

The Hitman mentioned you i think?

definately moon-something.

Did you used to have this turbo?

hey Birnie, yeh i take my car down to hitman once in a while to have a look over, but no ive been running standard turbo. Ive got an ITS turbo now that im consdering putting in, but the costs are gonna drive me up the wall. Did hitman give u a full tune or a touch up tune?

Yeah, prolly right. oops :thumbsup:

Ha, just noticed your squirrel balls ! Damn!

Times like those when a 30cm ruler would come in handy, flickk!!!.....

Never seen a cross eyed squirrel before but that would do it i reckon.

Hey Birnie. Sounds crap about the clutch. You can adjust them down on the clutch pedal. There is a clevis there where it attaches to the pedal (from master cylinder). You can undo the nut and thread the rod in or out. This is more for pedal position though. I only think this would make a difference if your clutch engages very high up the pedal.

HAHAHAHAHA!!

hey birnie, just a cuppla questions mate.

did u need a reg as well?

were u running standard coils?

what gap were u running?

didn;t need need a regulator as i had replacement injectors (s15's)

Gap was copper 0.8mm and i tapped em a bit closer to about 0.75 which were new the day b4 the tune.

Running standard coils but in top condition, hitman says looks like new.

Anyway, had the coil failure symptoms, we ripped the plugs out, down to 0.65 (SyndeyKid has recommended the same settings as a cheap fix)....no more popping ! Couldn't believe it ! :thumbsup:

Yeah sucks but i'm sure it was slipping a bit the day i had it done.

Could they have made a bad adjustment somewhere on the install.

Supposed to be a Exedy cushion/button capable of 260rwkws. bought thru Slide.

Although nowhere on the box does it mention Exedy or on the unit itself....is that normal?

They don't need to be worn in do they to grip properly?

Works great thru 1/2/3rd gears, only really notice it in 4th and it's just a bit around the 4000's revs

If I am not mistaken, SLIDE's clutch packages include an EXEDY clutch plate but the pressure plate is something else, hence the cheap price?

I bought an EXEDY clutch directly from EXEDY yesterday, HDB and it’s got an EXEDY pressure plate, which is pink with an EXEDY logo in black. I am fairly sure the clutch also has EXEDY engraving on it.

    • 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.
