In the states it would be easier for you to get torco fuel accelerator,its the same as klotz, the fuel iam going to get is called renegade fuels,its outta the states also but theres a guy who is a dealer just around the corner from my house so it works out perfect, I picked up 5 gallons today of 98 octane,gona try it out and send a log to sebastion at specialty z to see how it looks.

Lol I think I'll just be happy with 93 octane pump gas

Drove the car with 98 in it the other night,very very noticeable change,i still haven't even sent seb a log to do a tune change but it's already different feeling car just on the 92mm pulley,i couldnt imagine how much it would help if I was running the 85mm jinxx

I would spend a fortune driving it with 98+ octane as a daily driven car

Honestly you would be surprised, I got wayyyy better mileage on the 98 today on a long ride thru the Twisties then I do on 91, this renegade fuel is the real thing,very good stuff

I don't think there is anything like that close to me ... most everyone one switches over to e85

Ya this guy can also order e85, I just don't want to replace fuel pump just yet, iam really looking forward to see how my car will be with 85mm pulley and this fuel next season, it should be very interesting especially if I go to unleaded 109 octane,then I'll definitely have to drive to a dyno for some numbers.

I'm very pleased with mine using the 85mm it hits boost much better in early rpms than the 92mm I think the kit should have came with the 86mm right out the gate ..everything seems very stable ...I do need to change plugs still ...I'm still in stock plugs but will be switching to the gtr plugs

Ya you are right, I can't wait to run the 85mm pulley next summer, gona do the cjm fuel hat and fuel return system over the winter and iam gona run 109 octane fuel next summer.

Should turn out real nice ... you won't regret it

Update

Cars in storage for winter,heres a little info on next stage of my parts to be ordered/installed

Seibon ts vented hood- on its way
Cjmotorsports fuel return and hat
White line front stabilizer bar
Stillen front bumper
85 mm SC pulley - have it
Tires? Still haven't decided lol
Clutch pedal
Clutch for street/flywheel
Csc

I will be running 109 renegade unleaded race fuel,it can be mixed with 91 octane if iam in a jam. Should be around 12lbs of boost with the 85mm pulley, hoping for great results.

I'll post a dyno result as soon as I can get to one.

Been following this thread for a while and talking to some mebers. Can't wait to get boosted.

Will be ordering my gamma Stage 2 SC kit soon, and getting free 1000cc injectors ;)

Will grab a CJM Fuel system and hat. I will be on BP 98 Ultimate fuel. I am in Australia, so this fuel is everywhere.

Hope to hit atleast 470whp!!!!

Funny, I ordered the 1.5 upgrade kit in November and they sent an incorrect maf pipe for the drivers side,( it does not clear the Power steering pump) so, they resent a new set, same problem.. ohhh and they sent a 6 rib pulley ( need a 7 rib)... SMH....

Awesome,it's a great kit, straight forward to install and makes smooth power, you will love it,98 octane will be great, go ecutek if you can,amazing stuff,if you have any questions ask away.

Are you after the 92mm pulley?

Tiller have you upgraded to the 85mm yet

So if I want to stay around 10 psi, do I use the 88mm pulley from Gamma?

Are they OEM GTR Spark plugs or aftermarket?

I was given this part number for OEM Spark plugs for GTR:

NI-22401-JF01D

NVM:
Found it on Z1

Yes I hav the 85mm and it will be going on this upcoming summer along with other mods, waiting on Charles from DJ for fuel system,plus I will be running 110 race fuel

Yes I believe the 88mm is 10lbs approx

Yes the dilka8a8's are correct ones replacement,that's what aim currently using

Well, Instead of waiting on Gamma to get around to doing something, I ordered a 90mm 7 rib pulley from Kraftwerks ( There's a story with that sale also...) and I took the incorrect MAF pipe , reshaped and had it welded to fit my application. I also ended up painting the pipes with black wrinkle paint.
I have an 84mm pulley from the Stage 1 kit but am not looking to over stress my internals .

Ok sounds like things are moving along for you.
I purchased my 85mm from kraftwerks also,great prices.
Jinxx has been running the 85mm with no issues , good fuel setup and tune and these motors can handle 12lbs all day long, I think 84mm pulley might over spin the rotrex unit.

I haven't had any issues with my 85mm pulley which is 12lbs .. I did upgrade the fuel to the return system. My car is also a daily driver about 18k miles and supercharger has been installed since 1500 miles. The 85mm does over spin the supercharger a little at 7.5k rpm and is almost a perfect match at 7k rpm ... I rather max out at 7k and not redline the car ... some chose to run to redline to max out the supercharger. The perfect match would be the 88mm ... that should max the supercharger out about 7.5k Rpms ... IMO.. anything over 88mm is wasting supercharger potential.

So I did my first drive after installing the Stage 1.5 upgrade...
Originally my BOV plumbed back with the stage 1 kit. Relatively quiet but fluttered under medium acceleration.
Now, it vents to the atmosphere and is loud as hell, almost sounds like my wheezing grandma... for lack of a better description.. lol
I have a turbosmart plumb back and also a synapse diverter valve.
What are you guys running with what spring and how tightened down do you have the spring.
Is it loud also when it blows off?
I'm looking to quiet it down a bit...

Kentmo, the turbosmart bpv gets loud when off throttle. There's no real way to quiet it down. It turns heads and can scare the crap out of people! The spring tightness does not really matter, at least did not feel any real difference. I try to keep at medium tightness most of the time. The biggest issue with turbosmart bpv I've had is that the piston inside gets dirty, dry and eventually gets stuck or leaking boost when full throttle. Even once a month cleaning and lubing did not help. So after my last track day and very leaky bpv I decided to try something different. It took me 6 months of waiting to finally receive the synapse diverter valve. I haven't gotten a chance to install it yet. Also haven't been driving the car due to winter so I am not in real rush plus need to cut off and weld on new flange for the synapse diverter valve.

I also have the Synapse diverter valve and that one wheezes..lol
I might get creative, fabricate a pipe and plumb the valve back into the intake.
There is definitely room to run some 1.25" or 1.5" silicone /aluminum pipe from the valve to the intake. Weld on a 1.25"/1.5" flange to the intake.
That would quiet things down considerably.
Someone tell me why this should not be done.

Yes my bov is very loud and scares the crap outta people but I love it
I found when my bov got dirty the sound changes to fluttering so I removed it and clean it, then its back to normal again.
For my spring tension i usually tighten it just a turn or so past the rubber o-ring,not sure if it's right but it's been working fine for me, also the spring is the one that comes with the kit,I haven't replaced it.

Trying to make sure I understand, does it sort of sound like a rattlesnake?

I use the turbosmart valve that came with the kit ... and tighten just a turn past the rubber o-ring ...very little if any flutter and then it's at a very low rpm if it does. I did have issues with it sticking for the first 10k miles but each time it did I took it apart for cleaning and re polished the brass piston now it seems to never stick anymore .... knock on wood ..as far as loudness ..... it is very loud and very noticeable .... if got want to make it quieter you could attach a hose from the bpvand route it further down the car ... but for me I love the sounds and loudness of it ...can't really hide the whine of the supercharge so with out the bpv sound it would just sound weird to me

Lol ,yes I never thought of it like that but it does sound like a rattlesnake

Cj Motorsports shipped my s1e return kit and tophat, looking forward to the install and next stages of parts for my car :ughdance:

Time to change the air filter .... what a pain in the *** lol

Oh ya it's in a brutal spot

I invested in a maxjax hoist for my garage last august,best investment ever, whish I woulda had it when I was installing the kit last winter.

Where did you get the replacement filter from?

Also I installed the 85mm on the weekend :driving:

Haven't replaced it yet ... was hoping on a different style or a smaller filter for that spot ... I'll have to get it out to compare ...... can you feel the difference from the pulley change ?

Still lots of snow here, still a couple months till its back on the road

Installing new parts for now lol, new 32mm front sway bar, cjm fuel return :tup:

I'll be running 110 octane this summer, with a retune on ecutek from seb I should be making some decent power

Little update on my car,

Cj fuel return lines are installed,working on the fuel pump and hat right now.

Megan front swaybar installed

Seibon ts vented hood should be arriving tomorrow:excited:, hopefully it helps with getting some heat out of engine bay, hopefully make some good power on 110 octane this summer.

I haven't had any issue with engine bay heat ..... I just ordered a new air filter mine was destroyed from the exhaust pipe ... need a heat shield made .... I did buy another nismo ... a 2017 this one is black .....I still have the white one as well ...will be adding a boosted performance kit to it soon

Huh? So the filter sits so close to the exhaust that it gets ruined? It must suck in a lot of hot air then. :icon14:

Yes it's very close to exhaust the worst part of the kit in my opinion... but not really any other options that I know of ...

:eek:
