    boreing a ls to 82mm?

    When you change your cams or your compression you change cranking pressure. Since the intake cam keeps the intalve valve open slightly passed bottom dead center, some compression is bled off during the compression stroke. The result is less compression than your static compression (this is...

    boreing a ls to 82mm?

    Thats going to undercam the motor like crazy. 11.6:1 CR is the sweet spot for 404's.

    boreing a ls to 82mm?

    A little bit of displacement goes a long way. Keep in mind the difference in torque between a B18B and a B18C1/5 Thats a difference of 37cc's Going from 81.5mm to 82mm is almost as big a change. I don't know if I would rev past 8000rpm on stock sleeves opened up that much, but I wouldn't say...

    How to port a JDM ITR header

    Don't forget that the whole inside is going to be covered in carbon anyways, so surface texture isn't going to make much of a difference.

    GSR VS ITR

    :thumbsup: :thumbsup: :thumbsup: The factory ITR port job is junk. Most head porters would rather get a stock B16 head than try and revive a ITR head. They simply remove too much material and in the wrong places on the ITR head. Most of the gains from the ITR head are because of the...

    Honing a Honda block

    The helms manual specifically says that a hone is not necissary unless there are vertical scratches. I know several people that have installed new pistons with out honing and have perfect compression.

    DH Racing heads??

    Go with portflow. I would RUN away from DH.

    Frame Lock Review

    Actually some have noticed simimlar results as a byproduct of installing traction bars, since most traction bars include a large bar that attaches to the lower radiator support (which is the load bearing section of the front chassis). The large bar braces the same relative area as the frame...

    suspension guru i need some help

    Keep the front sway bar attached, removing it gets rid of a lot of camber control. Running a small amount of toe out in front, (1/8th total toe, or 1/16th toe out per side) will help you gain more traction up front (and thus allowing the rear to come out sooner).

    Pistons

    Which would be a problem if you didn't have piston rings.

    Pistons

    Why would a forged piston score the stock sleeves?

    What makes the power?

    I would like to note that on VTEC heads, in most cases the idle is hardly effected due to the ability to run low duration nonvtec lobes and high duration vtec lobes. Less duration in the lower end technically makes more power anyways.

    What makes the power?

    More lift tends to increase the peak WHP, where duration tends to shift the powerband upwards. (and as you move peak torque higher in the RPM band, it creates more HP due to the age old equation HP = Torque * RPM / 5252). The reason some cam manufactures choose to have less duration, is because...

    Block Posts, Where can I get some?

    www.theoldone.com Cheap to do, probably costs less than $100 for the posts, tap, drill bit, and epoxy.

    Are you looking to sell one of them by chance?

    need advice on a motor build

    The blox has much shorter, and larger runners, and a much larger plenum. In short that shifts the powerband higher, but the problem becomes that JG's runners are so much shorter, and so much larger, etc, that its beyond the usable point of a nonvtec powerband. With the LS rod stroke ratio...

    need advice on a motor build

    overkill? if you can stand it I honestly would go with the 405's if you don't plan on going with a 2L block. On a 1.8L I would stick with a Skunk2 mani, the 404s are very simmilar profile wise as the ITR cams. The skunk2 is an ITR replica, so conviently enough the manifold is already designed...

    Are ebay products crap in general?

    The intakes are one of the few things I would say are quality. Its pretty hard to mess up an intake, when the main things to look at are diameter and length. The filters often are sub-par, but a K&N will fix that. The short shifters I wouldn't get, as most of them are alluminum. The chances of...

    OBX camshafts

    Almost all of the products OBX sells are just rebadged, and bought from the same manufactures as other companies. If you look through their catalog you would be shocked at some of the things you see. Blitz filters, aeroquip fittings, the Greddy Turbo Kit (down to the blue box, which is in the...

    Can I use LS main caps on a B20 block?

    They NEED to be align honed. No ifs, ands or buts. The chances of all of the caps being perfect for that blocks casting is almost non-existant. Any machine shop should be able to do it for cheap.
