SBD Turbo - 400x vs 500x
Hi everyone,
I am looking to turbo my FRS at some point and was looking at the Speed By Design kits. I have been trying to find accounts of people who have tried both the 400x and 500x kits but have not had any luck. Can anyone who is familiar with either (preferably both) of these kits speak to them at all, or point me somewhere where this is documented? Based on horsepower alone, the 500x appears to be worth the extra money. Is there a significant increase in turbo lag? Are there any other considerations I'm not thinking of? |

Not much more turbo lag if at all because the 500x has a ball bearing. The increase in power probably wont be worth it unless you plan on building your motor.
Check out the SBD facebook group too. https://www.facebook.com/groups/SBDF...itOwnersGroup/ |

Ball bearing turbos are superior in every imaginable way. Where they really shine is in the transient response....it won't choke the motor so much under vacuum because they build boost coming off of deceleration and in between shifts much much quicker than journal bearing turbos do. The fact that it is available for just $500 more is pretty incredible, granted I know next to nothing about the turbine. I've heard that it's a GT3076 knock-off...that's about as far as I know about it. People usually make around 300 wheel or a bit more on pump gas with GT30 framed turbos on this car which is well within the safety zone if tuned properly. So I'm not sure where the built motor comment is coming from?

Join the FB Group James! THOUSANDS of people in there and over 1500 owners of the turbo kit.
There a wealth of information, not from my mouth, but from actual users of the kit. |

The oil cooler question is also dependent on severable variables. I feel that there is a lot of misinformation about there regarding what temperatures are acceptable for how most of these cars are driven. Let's be real...99 percent of the folk on this forum are not building race cars. We just want a quick street car. "ZOMG oil temps hitting 230 jew need an oil cooler ASAP"...I'm not one of those people. It takes quite a lot to break down modern synthetic oils. For a strictly street driven car, I would recommend switching to a 5w30 and running an OEM water to oil cooler unit. Works wonderfully for my application. In no way am I saying that an oil cooler is a bad idea...I'm an absolute sucker for modifications that support the health of my motor. Just don't buy into the boogeyman stuff is all I'm getting at. |
