Forget the L15 motors. If you have the money, go oldschool K24 or K20A2 motor. The 1.5T does great for what it is but I don't agree with some of the engineering that has gone into emissions and fuel economy that moves Honda from performance to econoboxes.
You only really need the intake cam, the HPFP and the hard fuel line from the Si/CRV head. In the end if you buy an upgraded DI system from Eman you would only need the intake cam.
I had forgotten about Emans fuel upgrade. He doesn’t have a web page for it and he’s notoriously slow. I wonder, about how pricey might it be? I definitely want a better pump setup.
Last time I was at his shop he said $19xx. Not sure if that's the kit only or installed out the door. He said it should give you about 25% more fuel capacity over the stock Si fuel system so it should be able to put you around the low 400 whp with ethanol and possibly higher with non ethanol race fuel
I believe 1900 USD. I know AAPerformance is working on one also and he claims it can be done for much cheaper.
I saw Alex from AA post about that as well, there is also one from quicknslick performance in San Diego in the works
To anyone reading, this won’t work in high load scenarios. The OEM are tri metal and designed for higher loads than the ones listed.
You would think that at this point it would be a "no brainer" for ARP to start producing a proper kit for these engines. Please let us know if anything comes of that. Though I've not read of any failures using the current "Hayabusa stud workaround", the solution is less than ideal.
It would be nice to see a photo of the actual workaround with the two washers to see how much thread engagement there is. I have the washers and studs. I will be putting a head on in 1.5 weeks but it would be nice to see a photo sooner. If no one has photos I will mock up the assembly and do one this weekend. I’m so curious.
