Adjustable Rising Rate Fuel Pressure Regulator

The Cartech regulators are designed specifically to add fuel to modified EFI
engines (turbos, superchargers and normally aspirated). This is accomplished by
using the manifold vac/pressure to drive the fuel pressure up as the boost
rises, or with the N/A engines, as the vacuum goes toward atmospheric.  If we
already build the best FPR’s (often called FMU’s), what’s the sanity of making
another?  The answer is to keep the copiers way behind. Our original FMU,
introduced in 1975, has been copied six times and is still used by four
companies.  The 2020 series regulator is the fourth generation design to come
from Cartech, and every new design has been better than the previous. Imagine
how vastly better these new designs are than that 25 year old relic the other
guys are still producing! Cartech FMU for $270

have few available.  These fittings will bolt right
on into your oil housing.  These fittings will work
on all Lexus and Toyota engines (V8).  We are

  1. Hi
    I did a conversion. Put a 4.3 UFZE in a 3.0d4d toyota hilux clubcab 4×4 woth its standard hilux gearbox and diffs. The diff ratios is 3.9… I would like to tune it a bit and make it go quicker from the start, make it perform better, not really looking for top speed, ut more performance. It also has a gearbox like shutter when taking off(could that be because of the diff ratio’s). I dont want to put on a supercharger or something like that? What can I do?

  2. Hi,
    Can someone tell me when the 5.2 ltr stroker kit will be available and how much please?
    Kind Regards

  3. Hey I’m looking the market to try and supercharge my 2UZ-FE VVTI 2005 Toyota Tundra SR5 2WD. I’m having a hard time finding a TRD supercharger or any supercharger for that matter that’s compatible. I know that they are very hard to come by but I was going to see if you could help me out some how. I also understand that the superchargers can cause engine failure in the VVTI models (From what I’ve heard online) but I’m open to taking the risk and want to make some boost in my truck.

  4. Currently run a 3UZFE stroked to 5.6 ltrs, 13:1 compression, running on E85 this engine was designed by TRD.
    I am having troubles with the head gaskets developing small compression leaks.
    I see you make a upgraded head stud, I was wondering if these are still available.
