Realtune has teamed up with South Bend to bring the proven clutch kits to the Mazdaspeed community. These are the same pressure plates and discs proven by Realtune in the Caliber market!

What we have here is the stage 2 setup. Torque capacity is 430ftlbs and includes the anti-chatter technology that again was proven in the Caliber SRT4 market.

I expect this stage to be our most popular with the smooth engagement, little to no noise and strong 430ftlb capacity

After years of using other vendors heads, Realtune has finally stepped up to bring you what we feel are the best cylinder head designs that we could come up with. Nothing out there did everything we wanted in one head. We were always modding the heads we were using and it just became a tedious thing to do. It was time for us to step up and offer a head that you can bolt on to your ride whether it is your daily driver or your dedicated race car. Realtune heads include bronze valve guides, extensive port work, extensive chamber work, stepped exhaust port. the lightest valve train on the market [good to .520 lift], and Realtune logo etching. If you want the head that Erabbit23, Project Whoop ass, or any of the big boy Realtune cars are using.....look no farther!  

**** PLEASE NOTE THERE IS A $300 refundable core charge if you are not sending in a head beforehand****  We also have Stage 3 heads available. Please email for more info

Realtune Performance CSRT4 Stage 2 Camshafts

**PLEASE READ all of the contents below**

These are full aftermarket pieces, not reground stock cam shafts so no cores are needed!
Gains can be seen in the attached dyno graph.
Gains +12whp and+18 wtrq  with ZERO tuning at @16psi with a huge gain past 6200. I expect 20whp if tuned on a stock style turbo and 30+whp on a big turbo
Rev range is 3000rpm to 7500rpm [only recommend past 6800 with a built motor]

*WARNING!!**
MUST use aftermarket valve springs. You can NOT use these without an upgraded valve spring so do not even try it.

These "can" be used without any tuning on MS1k but the 2-5% throttle range will be a bit choppy. Custom tune is highly recommended!

We are offering a discount on our valve spring and titanium retainer kit if purchased at the same time with our camshafts.
Realtune has teamed up with South Bend to bring the proven clutch kits to the Mazdaspeed community. These are the same pressure plates and discs proven by Realtune in the Caliber market!

What we have here is the stage 3 setup. Torque capacity is 500ftlbs and includes the anti-chatter technology that again was proven in the Caliber SRT4 market.

With the awesome torque capacity of 500ftlbs and the silky smooth engagement, I expect this to be our second most popular clutch setup! The stage 3 for the Caliber market is the most popular that we sell.

Realtune Billet 3/4 shift Fork Realtune Neon SRT4 Piston line
Our Price: $625.00
****SOLD OUT!!***     SORRY WE ARE NOT TAKING ORDERS AT THIS TIME


Are you sick of breaking the taps off of your stock shift fork? Are you sick of the modified factory forks going bad offered as performance upgrades?  Are the other billet forks priced too high? Then we have your golden ticket!

These will not break the tabs and cost a great deal less then what else is out on the market. Tried and true by Realtune : Home of the worlds eight out of the nine quickest 5 speed SRT4s

What you see is years of testing and having the other "performance" forks go bad on us. If you bolt a steel piece to the brass base it will loosen up and at the very least cause you to pull the gearset out to replace if not damage some internal pieces. As you can see we came up with a new way to attach the tab and that was to make the base thicker and slot it. The "tab" is then pressed in and welded....no more loose tab over time!

- This is a full replacement piece with NO core needed!! They also have a 2 year no hassle warranty :-)
Deep valve pockets
Built with 1000+hp needs in mind
Sold as a set of 4 with rings, locks, and pins


You can find these pistons in all of our Realtune built short blocks. We ONLY stock .020 but standard and .040 can be ordered with a 2-3 week wait time
