FAQ: These are some of the more frequently asked questions.
How much horsepower will my set up make?: The answer to this cannot be given without the use of a dyno. Please refer to the sticky that has dynographs from other users as a comparison for your upgrades. Understand though that all cars/dynos/parts are different, and what you see is not always what you get.
How do you get rid of a CEL with a race header?: So far the only way to get rid of a CEL is to either use the O2 simulator that Casper's Electronics (www.casperselectronics.com) makes or to use the K-Pro.
Will I run lean with Hondata's #4 reflash and a race header? : The only way to properly answer this question is to have the a/f ratio checked with a lambda meter. This can be done at a local tuning shop on the dyno or with an aftermarket a/f meter.
When is Hytech's kit coming out?: It does not look like it ever will. On top of that, the type setup they are supposedly using can be done for considerably less than what they were going to charge. Vaporware as some call it.
Does my car have the dual valve springs or single valve springs?:
For this I will quote Glimpse:
"33,312 (VIN number) and below for the 2002 Type S. Changes were also made in the CTR.
This was given by the TSB, but I don't take it as the gospel.
I also feel I should mention that Honda changed to a single spring design to minimize damage during a misshift. The dual valve springs are in no way weaker. A dual spring setup is usually optimal in high-reving motors as they resist valve float at high engine speed. However, during a misshift they are more likely to hold the valve in the chamber, leading to catastrophic engine damage. The softer single spring design is more likely to float, but is less likely to hold down the valve. The point of all of this being, don't think your valve springs are inferior if you have a 2002 with dual springs. You can still rev just as high as the single springs (actually, higher)."
Will I get a good answer by yelling and cursing at the people that have been around for a long time?: NO! Read the forum rules and stickies before posting anything and getting mad when anyone who has been around for a minute tells you to do a search without answering your question.
