Pulleys

"Z"en

For 62k+, you will be dealing with belt tension and slip when putting the K$N filter on.

Great feedback from everyone...TY Gents... I also forgot to mention that I have TBatts idler pulley/belt upgrade. Hoping that helps keep things down. I am also like Redondoaveb and using the turbo guard with no filter.

Are the spacers needed for the upgrade @redondoaveb for the jackshaft/SC pulley upgrades? Its been a minute since I’ve been on the forums but I also recall ur set up having the fabricated wastegate to the charge pipe. I recalled u referring me to Alex with L-Spec up in Hawthorne. I also reached out to Seb since he’s the one that has tuned my Z and was working/tuning ur Z at the time and he mentioned they (Specialty Z) were considering fabricating the piping and wastegate set up for open sell to others like myself....but not sure if that ever materialized or not. I also emailed Alex but last I heard they were working on a putting a pricing group together but received no other update since that time which was about almost a year ago. LOL

If the wastegate upgrade isn’t available then I won’t be going for boost anywhere in ur range... @redondoaveb. Don’t think it would be feasible for me without that and a boost controller as I am on a stock block with stock internals ...I’m using the CJM S1-SE set up what the 485 Walbro pump/CJM Top hat 1000cc Bosch Injectors for plumbing but unfortunately my fuel options are limited. The weather out here in the West Pacific doesn’t work well with E-85 or any flex type fuel due to our humidity. 91 at the pump is the highest we get with the exception of course of VP MS109 from our local race shop that ships that good stuff in. But at $120 for a five gallon can...we save that strictly for track days/money race events...Lol. We do have great sunny weather year round and nice white sandy beaches though LOL!!!!! Give and take I guess... Oh well...

Since a little more has been shared on my set up any great advise from those of u with the experience here would be greatly appreciated. Thank you for laying down the groundwork for improving this kit. If it wasn’t for TopGunz and guys like you on this forum we would all be stuck with the basic Stillen Kit.

If 91 is the only fuel you're going to run then the wastegate wouldn't be needed. You can run around 13 psi on 91 before knock. If you plan on boosting above that level by using a higher octane fuel then you would need the wastgate in order to dump excess boost when you're running 91. I bet if you contacted Seb, he would be able to build you a custom set up like he did with me.
