Thats awesome! Did you have to cut any of the Y pipe? IC brackets fit right up? Looks like the hot side pipe (L pipe) needed an extension.

I bet you can get by with a bigger filter. I can send you a link to one if you want that will probably gain a psi.

Also, I noticed your manifold cooler is still in there. That thing should definitely come out. I know it sucks taking the manifold off but it will be worth it.

the intercooler brackets mount up but you can only use two bolts on each one that i feel is enough to hold it on. this picture was taken before i moved it around, the intercooler bolts up to both sets of holes if that makes sense. i ended up moving it over cause it looked stretched.

I also did remove the manifold cooler it was just something i did after mounting up everything. I don't think a bigger filter will fit in the space i have, it was a challenge and a half trying to wiggle the blower assembly back into where it sits.

Ill chime back in as my tuning continues as I am remote tuning. Ill probably jump on a dyno eventually and ill also throw that in here.

Thanks again for sharing the kit with everyone!

Sounds good. Let me know what modifications that were required because there have been a handful of other 350 HR guys wanting the kit but I had been telling them I doubt it will fit. Do you have this posted on any 350 sites?

i have it posted on a nismo page but no out right 350 sites. i need to remove the front bumper to see where i cut. the y pipe could be adjusted a bit to make fitting it easier. you do need to widen the hole that leads it into the engine bay but that could be fixed by changing the angles. also making the first throttle body cupler an inch or so longer would make mounting it all up way easier.

Thanks topgunz for the all the questions you answered. My tuner was Nick@ Fastech Motorsport. He was amazed by this kit for what it did and how easy was installation.

Isn't there is bumper you can buy that clears the intercooler? Not bumper cover but the bumper.

Are you talking about the crash bar?

It goes. Fascia-bumper support-crash bar.

Yes the crash bar.

The Fast Intentions crash bar clears it fine.

Cool I will have a look at it. Thanks

I'm trying to upgrade the impeller but I'm having a hard time taking the blower out to send it out. sorry for the noob question but could anyone help me out with it? i know someone mentioned how on here but i cant find it.

Download the install guide off Stillen's site. You want to remove the belt and then unbolt the mounting bracket that holds the pulleys and the supercharger.

Send it out?? why? the impeller takes 15 mins to change, super easy.

Air to Air intake upgrade
 

Thought you all might be interested in an intake mod for the air to air kit. A fair bit of design and engineering went in to this over the last few months. Along with the air intake upgrade I had the supercharger rebuilt with upgraded Si trim impeller/compressor. The main benefit of all this is more torque in the mid range. Other benefits are a much bigger/better air filer resulting in better breathing, no need to remove the sc to replace the filter and much better/easier adjustment of jack shaft tension.

What diameter piping were you able to fit in there? 2.5"

Wow you had a cast coupler made?! Thats pretty cool. Id love to see some before and after with the short filter vs this cast intake with conical.

Nice work!

Thanks and yes a cast aluminium coupler! :tup:

Before and after.:tiphat:

First is stock Stillen, second is air to air and third is the new intake.

You can notice the max power and torque being reached at progressively less rpm over the 3 graphs.

Yes about 2.5" or a bit more I think.

I received an email from a guy in Texas about my extra pulley kit and thought I would share the information.

I have a Stillen S/C Kit & 129,000 miles of experience with it.
I'm interested in purchasing your add-on idler-pulley & HD Belt KIT that puts extra 'wrap' on the front jackshaft pulley.
Can you help me out ? I hope you are still active with the Z's.
I bought mine new in 2009 -> 189,000 miles now & work on it myself.
I rip camaro ss, mustang gt, 328 bimmers, turbo'd 4 bangers all day long.
Last gt that baited me, I pointed for him to go, & afterwards he just rolled down his window, & shook his head like 'why did I do that' haha I'm Speed Density tuned by Sebs using ecutek.

His kit shipped out this morning.

How can I get one?

I too would like info on ordering this. I hate having to remove SC just to change air filter it very dusty here in AZ.

I'm going to have to talk to my shop and see what could be done for you OS enthusiasts as far as cost, lead time, manufacture and delivery is concerned.

Another thing that I think will make this harder is that you will have to get the outside diameter of the intake on your volute machined along with the two sealing O ring grooves to be machined in. The inside diameter of the cast intake will have to be machined to suit as well and then there's the fabricated intake pipe up to the cast adapter and CNC machined bracket for the supercharger itself.

I'm not sure if that would be better to be done here or for you to get it done in your own area/country.

This has been a very much custom mod for myself (so far). To make it available to other forum members is yet to be worked out, but I'm happy for any ideas but be weary of what it might cost!

Oh and one other important thing! I had to get some of my AC piping cut and re routed to enable this intake mod which was of course needed a re gas.

Tbatt and Wideglide,

If changing the filter is that much of an issue, then I would think the minimal amount of power you lose by going with the old stillen coupler would suffice. Although, this new cast coupler is definitely an upgrade from the silicone one and may flow more air.

This is what my high flow cats looked like after a bunch of miles and part of a track day. Just more proof of what happens to them behind the headers on a supercharged car. No wonder a driver behind me said I had sparks coming out of the exhaust. :eek:

After switching to A2A (UK developed) the tuner noticed that the boost was not what he was expecting. I upgraded the SC from a SCI to and SI. Boost was better, as expected but still low.

I now have something similar, I dont have a coupler but some alterations were made so that the intake pipe into the SC was not restricted. I now have a large cone that sits above the FMIC with the pipe the same diameter as the SC charge opening with no restriction. This means I can change the filter without SC removal, but I still need to remove the bumper.

Boost was not so high that I have reverted back to the standard pulley. Car is currently sitting around 550bhp/400ft-lb, which is as high as I want to go with the A/T.

I also removed the MAFs and have the car Density mapped to remove the recirc piping and save room.

My berks HFC died in less then a year after installing this kit, went with ART pipes.
Cats just can't handle the heat, at least not in the stock location!

The only cars I've seen that have issues with cats are the ones that aren't hitting AFR targets. Too lean or too rich will cause problems. I've tuned several with STOCK cats and aftermarket cats and all of them are still doing just fine, even with upgraded impellers, pulleys, etc.

Well SEB tuned my car AFR is right where it should be. May be it was the berks that were the problem, I just know when we replaced them they rattled and pieces were falling out of them.

Anyone know where I could order another one? Or maybe a part # for it?

Part # is 36225 and here's one place although I got mine from Amazon.

Thanks bud I appreciate it!

Is this a part you should always keep an extra on hand?

No. Even if the bearing starts going it will probably just get noisy. Since these are readily available you could get one in a few days. Of course they're so inexpensive it certainly wouldn't break the bank to have an extra on hand though.

TopgunZ install
 

Hello all. I am about to install the TopgunZ A2A kit and was wondering if anyone knows exactly how to remove the SC so I can turn the housing. Not sure if the belts need to come off first or pulleys or what. Any help would be appreciated. Thanks.

Remove bumper. Remove intake Y pipe and boot to SC. Loosen the serpentine belt using a 3/8" drive on the auto tensioner. Remove the 8 or so bolts holding the supercharger bracket on to the face of the engine. Pull entire assembly out.

PM me your email and I can send the stillen install manual so you can take a look how it goes on, just reverse it.

I’ll take a look at it. If I’m stuck I’ll get back to you. Thanks
I also pm’d you. Didn’t know you had replied. Thanks

Are there any good indicators of belt slip aside from rubber shavings around blower? I have minimal shavings, i don’t see any slip on datalogs through 7300rpm it makes or at least holds boost at 1.3bars but i’m still peaking at 4.5psi. I’m using soapy spray around supercharger and coupler for leaks, and then pressurized smoke test from front of intercooler.
That said, still managed to make a STI sell his car, and i was pretty happy with how well i hung with an R6 and very modded GTR all things considered and i’m not even on e85 tuning yet

Your only making 4.5psi? Have you taken it to the dyno? What is your whp?

According to the rep I talked to at Vortech, if you see any belt dust, you have belt slippage.
