Only thing I haven't decided on is what camshafts to get. I definitely don't want 4P camshafts or the DC elite series as they are reportedly harsh on the valve train. I just want a set of cams that can take advantage of my upgraded valve train while also retaining as much midrange power as possible. But if drop in cams end up being the right choice then I am not opposed to that. |

I'd make a post on K20A with your goals, that LotusElise guy will probably steer you to a set of Todas. Oil temp followup - I talked to KPower, explained the situation and what I was thinking about doing, and they graciously made me up a patch harness to test out. Was supposed to show up today but Fedex hates me so maybe tomorrow. It is a shielded wire set w/ ground for the DBW TB to the 54 pin engine harness plug for the DBW signal wires and another set of shielded wires w/ ground for the jumper harness from the adapter board to the Haltech. If this doesn't work I also ordered pins for both plugs and shielded wire to shield the DBW TB power wires.

Yeah I've got it already. I wanna say it took right around a month full turn around?
Toda as mentioned will be the general consensus for mid range by a couple guys on k20a.org. I went with the DC stage 4 due to the dyno number/curve that Kpower got with theirs. Quote:

Thinking about going to a 40 weight oil. Last track day I was seeing oil pressure going down to 15 psi at idle after really hot sessions. oil was getting to 230-240, which isn't even really bad. Anyone else experience this or run a 5w40 or something? this is still just a junk yard motor with refreshed timing components and a 4piston oil pump.

looking at some of the K24 videos online, some builders get new chains and guides in addition to new tensioners when doing the cams. Is that necessary, are you guys doing that too?

2. Chain - ABSOLUTELY replace the chain with a brand new unit. The K24 chains are incredibly notorious for stretching out: causing power loss of anywhere from 5-30hp+ and at worse, destroying your engine. Oddly enough K20 chains generally don't have stretching issues like K24 chains.

Decided on Toda D cams to go with my 4pistons TSX head. While I don't think they will be the best combo with my current stock block, down the road when I build a block with high compression and a stroker kit they will be perfect. Really good mid range torque with a focus on power below 8200 rpm.

I made my NASA classing dyno pulls today, so this would be pretty comparable to anyone else using those settings. In effort to drag my classing horsepower down (it is done with a formula to get an average) and reliability I set the limiter at 7800. NASA average was 196whp, coincidentally same as my old S2000, which is absolutely perfect and what I wanted.
So, since everything here is fairly comparable I give you: * note: K24 and S2000 dyno graph scales go to 9k, both FA BRZs go to 8k My dyno today - bone stock KPower K24 swap, pump 91 Full bolt-on first gen BRZ NASA TT5 car, pump 91 Stock plus Cleib catback and air filter second gen BRZ NASA TT5 car, pump 91 Full bolt-on AP1 S2000 TT4 (lol) car, pump 91 As for the electrical interference stuff, Fedex legit ate the harness KPower sent me so I filed a claim with them. KPower was kind enough to send me another harness which showed up yesterday, I will test it tonight.
