You really don't need squirters unless you plan to be doing extended 5th and 6th gear pulls without an oil cooler.

Kial, congrats on your setup. I am preparing a similar project inspired by yours. I got a 99mm crank and custom ordered a set of crower rods along with some JE pistons (88.5mm). Darton sleeves are installed in the block and compression should be around 12.5:1. I also got a ported intake manifold, a 68mm throttle, J's exhaust manifold and custom 76mm exhaust.

Now I really do not know what to do with the camshafts...Judging from your plot, stock cams are fine up to 8300 which I plan to rev this engine. I might get an Ap2 exhaust cam (I have Ap1 cams) and some cam gears to play but I feel the engine wants sth bigger. I have some optimistic expectations, going for over 275whp (dynapack). Project should have finished by late October.

I also just finished a stroked F20C engine, with Ap2 crank/rods and Ap1 pistons. THe engine also had TOda A2 cams, skunk2 valve springs, DC header (I know...) custom 70mm exhaust, ported intake manifold, spoon TB, Green intake, AEM EMS tuned -> 255whp & 173wtq. Awesome engine, feels really strong.

Why not go with toda cams then if you already have experience with them?

Well, I have not back back dyno tests of Toda A2 vs stock cams and scanning the forum I've seen that they provide minimal gains compared to stock. As a result, I do not think they worth the cost and hassle of installing them (since they also tend to wear the tensioner faster). What about hytech cams? ANy experiences?

even then i wouldn't worry, I drove my car from florida to north carolina with an average of about 90mph, I know for a fact we drove 2 hours at 100+mph and my car ran pretty cool, there's just so much air exchange going on at those speeds that everything stays cool, if your NA!

Honda put them there for a reason. I will try to keep them at all costs. Oil pressure is more than enough on our motors anyway.

The profile of the Toda cams compared to the stock is so similar, it's hard to see why they would make a lot of gains. With the Ap1/Ap2 cam combo, the profile on the OEMs is in some ways more aggressive. The Todas probably have faster ramps, but you pay for that in valve seat longevity anyway. With gears and stock cams you have a safe combination that makes decent power.

Correct me if im wrong here, but oil squirtsersare for keeping the pistons them selves cooler right? Sounds rather important to me.

Correct. Piston scuffing is much easier at extended periods of high power (5th and 6th pulls). Also, the piston pin is much better oiled withe squirters.
