Get a better regulator, those Sard ones aren't good at dampening the fuel pulsation also they're not E85 friendly. I always install Turbosmart FPR1200 FPRs on cars I work on.

[jay-rod]

Well....that sucks.
Thanks for the tip.

[Dose Pipe Sutututu]

Save you the headache, also because the Adaptronic is semi sequential injection there will be a level of "thumping" from the fuel system. I had to install an additional fuel pulsation damper by Radium to suppress the fuel pulsations to get full control of my injectors. Had leaning out issues in low load, and high rpm areas due to the pulsation not being dampened. 

[Leroy Peterson]

Interesting... Thanks for the heads up

[jay-rod]

Could the stock damper in a 34 be ok to keep then?
Because the 34 has an extra damper that the non neos dont have.

[Dose Pipe Sutututu]

yes do keep it

I guess some of yous already seen, we've started modding RB20det for the next couple of week and see how far we can get before hurting driving ability.

So the car is an 93 model GTS-4, good condition and solid. Its fully stock with an cat back exhaust and a blitz return flow cooler only. Its running a R33 GTST turbocharger at 10psi and it is as slow as it gets. 

So far I've ordered:

Split fire coil packs

Z32 AFM

470L Walbro pump

JJR front pipe with 100 cell cat

650cc Siemens injectors

Nistune ECU

The first turbo I will be fitting will be an ball bearing ATR43SS-1.

Obviously that's just a RB25 timing belt cover? you don't have VCT working on the 20 do you? haha. 

 

Keenly awaiting results

that's a funny looking R32

Yuh.  If the rear guards weren't so pox I'd almost consider doing such a thing to mine.  Although there's so much tupperware on it that I'd inevitably feel bad about doing it.

The worst thing about that particular instance that Stao has bought though is that it appears to have been painted by 3 different people in 3 different locations, then assembled!

hopeless spellink.

LOL just goes to show, you can look at the pics and think it's fine, and never really know until you see it

[hypergear]

For the amount of exterior work is not bad. It used to be Jesse Customs personal car two years ago. any way, parts started to arrive and I will update with prices and places.

I'm using siemens 610cc injectors @ $60 each and Walbro 470L pump @ $200 each from Injectorsonline . com

Z32 AFM and plug cost $250 from Dev industries

Interesting choice of injectors, but I guess the price point and fitment make it good.

Here is one more result that are worth posting.

This is from one of my troubled customers whom like many others using stealth setups including a return flow cooler and a silent exhaust. Obviously it made a petty 260rwkws P98 using our ATR43SS2 turbocharger with a massive boost drop. The SS2 however have held a dead flat 20psi on my R33 peeking 302rwkws. Fixing that boost drop problem, he went all the troubles fitting up an External gate that made only a 5kws gain. His disappointment anger and frustration has been directed to the turbo and my self.   

During that time, initial ATR45SAT was first made and tested by Havoc Fabrications at 420rwkws. An upgrade request was made by the customer so the same turbo was built and sent for the exchange of the ATR43SS2 which I'm yet to receive. With nothing else apart from the turbo change and E85, the car made an disappointing 354rwkws, that have sparked more heated conversations, to prove my product I have later managed to use the same turbo beating his E85 result running internal gate on less boost.

Red- My internally gated result vs Blue - under performing externally gated result

 

Finding out reasons and answers in solving those issues, I have bought my 2nd and 3rd R34, picked the exact same mods used, guess what I ended up with same crappy result. Investigation pointed to the Blitz return flow cooler, the 2.5 inches resonator inside Jap exhausts as well as the EPA approved compliance cat, test results of those are documented in my earlier updates of this thread.

 

A proper front mount cooler is finally fitted, with a good cold air induction system and a free flow exhaust installed. using the same turbocharger the car has now hit 400rwkws on E85 fuel:

Vs controlled result:

 

 

This is an perfect example of how important it is picking the right supporting and differences it makes to overall performance.

What make is that airbox please?

[Dan_J]

^ looks like a custom CAI box to suit factory snorkel 

stao, thats a great price on the afm, i cant seem to find Dev industries anywhere , care to link me up to where i can purchase it ? 

thanks

Very cool, internal or external gate? What's the brass fitting on the left?

The boost sense line for the wastegate

External of course

Moving up from a atr43ss2 external gate.

I've had this small issue recently with my ATR43-SS2 (2013) where I occasionally find a drop of oil underneath the front housing. I have checked the water and oil lines and they are all fine and tight. I've also been conscious to wipe the housing clean each time in an effort to pinpoint where it's coming from.

I took the photo below just then, you can see a bit of oil collecting at the edge of the housing and right under one of the housing bolts. It also looks a little wet right around the bolt so I'm wondering if that's the cause? I chucked a 13mm socket in there and tightened it a touch (it turned easy enough) but didn't want to overdo it as I don't know the torque specs.

@hypergear Tao have you seen these turbos spring a leak there before? What's the torque specs on the housing bolts? Cheers
