  • Model: V3-ALPHA-GT42RS
  • Manufactured by: Himni Racing

The FD V3 ALPHA line of turbos kits are available in several different turbochargers. The main difference in the each kit is the turbo itself. (along w/ related install parts) Each kit has a 1-5 star rating to indicate how quickly the turbo spools in relation to the amount of HP it produces. Ball bearing turbos cost more but of course spool faster. Journal bearing units spool a bit slower but are more cost effective. The HP numbers are provided to give you an idea of what you can expect to produce at 10-15 psi. Variables such as tuning, can yield different results from each engine. A pro tune is always recommended for maximum output.

- HR FD V3 Alpha GT42RS/GT4202R, GTX42RS/GTX4202R Kit (102mm Comp Exd)
- HP: 385-500 @ 10- 16 psi
- Response/Spool: *****
- :::Note::: The 42RS Alpha kit is also available in the X (GTX-R) turbo upgrade. This turns the turbo in the GTX4202R, utilizing the Garrett Fully Machined, Forged, Billet, lightweight compressor wheel. The main advantage to the X upgrade is blindingly quick response due to reduced rotating mass & higher available pressure ratios. Select GTX-R option only when high (28+) boost is needed.

HR V3 Alpha Turbo Exhaust Manifold Info:
At the heart of the system, the HR V3 Alpha high mount T4 manifold is Himni Racing's exclusive design. Over 2 years of development, the entire manifold is constructed of solid 304 Stainless Steel, CAD designed & hand made exclusively by Himni Racing in the USA. Longer runner & large bore tube design maximizes mid-range & top end HP. A fully divided & tuned, mandrel bent tubular manifold that optimizes turbo response, efficacy & HP. HR rainbow TIG welded, smooth ported for max flow with integrated SS heat shield that lowers temps for increased detonation resistance & more HP. 1/2" thick flanges that will not warp or crack. Optimum & aggressive turbo placement, the V3 Alpha TRUE top mount turbo placement keeps the turbos heat off the intake manifold thus lowering intake temps even more. High flow twin wastegate runners achieves perfect balance & a truly divided design. The best FD manifold on the market, each employs the HR ECS (Extreme Collar System) for the ultimate in high heat durability & superior to flange-flange rod supports. Includes mounting studs & premium copper clad nuts as seen in the photos. Made in USA using only US raw materials.

How difficult is the FD V3 Alpha kit to install?
Installation is relatively simple, very straight forward & is installed in about 2-4 hours accounting for removal of the stock parts. All the lines arrive preassembled with their fittings, adapters, etc. already attached. Mounting bolts, nuts & studs are either already installed or slid through their component & tied into their location on the part. No piles of hardware that require detective work. Only basic hand tools are needed for installation.
What are the warranty details?
The exhaust manifold, downpipe & other small metal parts are covered for as long as you own it. In the unlikely event that they ever crack or break, we'll repair or replace it for free. Just send us an email & we'll take care of it. The turbo comes with Garrett's 1 year warranty, the wastegate comes with Tial's warranty.
Should I use exhaust wrap?
On the manifold, it's not recommended. Ceramic coating is more effective at reducing heat & is less brutal on the part. On the downpipe, wrap away if you like, though again, ceramic coat is better.
Each kit comes with lifetime customer service & tech support for as long as you own it!
Is the FD V3 kits available with the wastegate plumbed back to the downpipe, rather than open wastegate?
Yes. The kit comes with SS tubes that routs the wastegate dump under the car by default. This is the layout that's preferred by most. But it's also available with the wastegated exhaust rerouted back to the downpipe for no extra cost. Just leave a note during checkout requesting it to be rerouted to the D/P & we'll take care of it.
Do I need to upgrade my fueling?
The stock fuel system will only supply enough fuel for about 6-7 psi, depending on the HR FD V3 kit you select. Fuel upgrades are recommended for boost levels above 6 psi. The V3 kits flow A LOT more air then the OEM turbo & require more fuel.
What fuel upgrades should I do for boost pressures above 6 psi?
This is a in depth question with lots of different options ranging from mild to all out, depending on how much boost you want to run & what type of budget you have. Generally speaking, common upgrades include larger fuel injectors & fuel pump, adjustable fuel pressure regulator, piggy back fuel controller or even a stand-alone EMS. If you are unsure what's best for your needs, just send us an email at himniracing@digital.net
Are the HR V3 kits used with the stock air pump?
No, the OE air pump needs to be removed. This is a popular upgrade for all FD RX-7‘s & we recommend the Pineapple racing FD air pump removal/ idler pulley kit. Contact us for details & discount pricing.
