Hello all. I am in the process of replacing my head gasket and am thinking of possibly installing some new valvetrain components. If I do so (or even as it is set up already) I think I might need to look into some sort of tuning system. The performance modifications to my car are as follows:
- DC stainless headers (soon to be replaced with Tri-Y headers)
- Stock Cat (soon to be replaced with 2.5" Magnaflow cat)
- Greddy cat-back exhaust (soon to be replaced with a 2.5" stainless system with 4" Magnaflow resonator and 5x8" Magnaflow muffler)
- Type S Camshafts
- Type S Pistons
- Type S Dynamic Intake
- Head milled slightly when rebuilt
- Blox insulated IM gasket
- Stock intake manifold (soon to have Blacktrax Dual IM spacer kit and IAB valve delete)
- Ported and polished intake runners
- Valve job (3-angle stock when rebuilt)
- Stock fuel and ignition system
I will be using a Cometic 0.027" head gasket and ARP head studs when I re-install the head. I also switched my timing belt tensioner over to the manual tensioner this weekend. The timing belt was replaced when the engine was rebuilt 3500 miles ago but I didn't have the money to do extra stuff then, so I left the auto tensioner in. I have since graduated from college and have a little money to put into my car.
So I was thinking I would just leave the valvetrain alone, but now since the head is already off (and I don't want to have to do any of this ever again), I am thinking about going with some higher performance valvetrain components. I am not sure yet if I will do any more changes or not, but the options I am thinking off are as follows:
- Keep Type S cams and stock valves and buy Blox (or other) Ti retainers and valve springs
- Keep stock valves and get new Blox Type B cams, Ti retainers, and valve springs
- Same as 2 but swap out the valves for some like the Skunk2 Pro high compression stainless valves or something similar
**I have some Hayame (or something - cheap) adjustable cam gears that came with my Type S cams that I might install if I need to tweak the timing. When the engine was rebuilt and the Type S stuff was installed, I just left the cam gears stock for some reason.
I know if I do this level of modification to the engine I will get the most out of it by dyno tuning it and using some sort of EMS. The fuel system will probably need to be updated as well. I currently just have the Fields VAFC that came with the car when I bought it 7 years ago. After doing some research about stand alone EMS options, I haven't found any definitive information if any can be used while keeping the ATTS functioning properly. I know that if you use the Hondata systems and convert to OBDI you will lose the ATTS. Please correct me if I am wrong. From what I can tell, the AEM EMS might allow the ATTS use since it is supposed to be a plug and play ECU system. Any help will be appreciated as well as any suggestions on what valvetrain components to use. Thanks!
