Now demised...

Like I always says, it's more dangerous to drive on the streets than on the track -- where everybody is going in the same direction.

Do you have any left over Maruha inner HLA shims? I need a couple or even just 1 of the smaller ones to spec my whole head before i order a shim kit. boltz69@hotmail.com

Sorry Tim, I had not been checking CarDomain for a long long time and don't recall receiving email notification about your post. Anyways, hope my answer is not too late. Regarding Chikara, Ocean and I are long time good friends. My TWM ITB project actually started by taking over his TWM ITB set with his custom fabricated manifold. I later traded-in the decade-old TWM set with a new one and continue on with my own R&D. It was not until my TWM setup was well-developed before Maruha was readily available.

Chris: I am thinking of have Chikara install the Maruha ITB this summer and I would like to know if you have dealt with them and do they know their stuff especially in tunning? What is your impression of their ITB skill level? what was the reason you did not go with the Maruha but TWM instead? chikara is in your backyard. Tim

Triple88A, I made 130rwhp at no more than 7000rpm. It's actually not that hard for the 1.6L NA with 10.2CR and no IRTB. If you're willing to go for 11CR, 130rwhp is not a problem.

Sweet ride :) I love the IRTB. I'm thinking of going the other way w/ FI instead but still thats one nice ride you have there. 130whp? How many rpm are you running it to?
