ok guys what can i do to get good power out of my DA everyday car i just what to look stock but have good power no ls vtec or turbo all motor i just what to pull on b16 or b18c. motor wise i doing a rebuilt so pistons /rods /head gasket/headwork/any help. thanks

b16 pistons, crower cams and a b16/type r tranny and your good

the B16 tranny will help a lot

i mostly depends on you budget but def bump up your comp and get biger cam and normal bolt on's im/headers/cat bac and a b16 or gsr trans and your good

best bang for the buck is nitrous...

Good: Crower Cams (403's), Cam gears, Dual v.s., Intake manifold, Bored throttle body, I/H/E, and tune. (Tranny optional but useful)

Better: B16 Pistons, Crower Cams (403's or 404's), Cam gears, Dual v.s., Intake manifold, Bored throttle body, I/H/E, and tune.

You will need a really good tuner if you go with the 404 cams to get the idle as close to stock as possible. Keep in mind the extra expenses such as seals, gaskets, etc. They can add up pretty quick.

i think i will go with better: whats Dual v.s. and I/H/E it think i/h/e stands for injector/headers/exhaust oh and what transmission. thanks for the help

intake, header and exhaust.

dual v.s. = dual valve springs.

get a gsr tran their nat to hard to find at a good price and is also good for dd the b16 trans will be a little more aggessive

what compression b16a pistons should i use im running stock cyl bore 81mm and what kind of dual v.s. should i use and thanks for letting me know what dual v.s. stand for

Are you wanting to use a stock cast piston or are you going forged? I'd stick with cast and run a P30 piston.

As far as valvetrain... I recommend Supertech springs and retainers.

yah make sure u get the jdm p30 pistons they have a higher cc than the usdm ones and then u can run a more aggressive cam like the crower 403's

ok then i will go with the jdm p30 pistons and crower 403 cams port and polish 3 angel valve job b16a trans with a ls 5th gear Cam gears, Dual v.s., Intake manifold, Bored throttle body, I/H/E, and tune. what a good
Engine Management for Tuning remember its a dd driven car. thanks

For EMS it depends on your location. Ask your local tuner or the tuner you plan to go to. They will tell you what they have experience with. Swapping out a ls 5th gear in a b16a is always fun (just kidding) but if you want that higher gear for highway driving than its an option. Unless you know someone for a better price machine work is never cheap so watch out for the price on your valve job and port and polish.

itr pistons, crower 403's or bisi stage 2 cams, cam gears, 4-2-1 header, 2.5 exhaust, kms dual valve springs (same as supertch, only cheaper), head port (ls head flows like shit), arp rod bolts (oem tend to break), 12-14lbs. flywheel, and a good tune.

i thought that the p30 pistons where better then itr pistons for a 1990 ls or b18a stock bore 81mm and if the (ls head flows like shit) then what head should i use i mean if i have to go vtec then b16a it is but like i said i like to use stock or even a later odb1 ls head but form what ive seen there is no big diffrents right

in my case i prefer itr pistons over b16 pistons for two reasons: one, they bump your compression but not so high as ctr pistons; two, less probability on piston to valve sex. the flatter surface of the itr pistons aids better than the b16's in the combustion proccess.


yes the ls head flows like shit, but nothing that a good port can't fix.

The ls head does flow like shit but thats the point of the port. Itr pistons have lower compression but leaves a little more clearence between the valve and piston. Just as long as your timing is dead on balls accurate.

well now i dont know what to do should i go itr pistons or p30s i mean if there is a risk with valve and piston clearence between p30s then i better use itr right whats the comp on them any ways and will i have a problem with my ls rods fitting do they make them for stock 81mm bore and thanks for replying guys u are helping me.

Also in regards to the ITRs they have some antifriction coating on them.

I dont think the risk of P2V contact is as high as they're making it sound with the P30'ss, if it was you'd hear about bent valves in all most every all motor LS build.

Check compression here. It's an estimated compression, so dont take it to heart.

an LS with P30's = 10.96:1
" " " PR3's = 10.76:1
" " " USDM ITR's = 10.52:1 (JDM ITR's = 11.00:1)
" " " USDM GSR's = 9.60:1 (JDM GSR's = 10.14:1)

That's using a stock 3 layer headgasket and LS rods. That does not take into account milling the head or decking the block.
