*B20B Questions*

[KaMaKaZiPyRo]

ight, well i dont really plan on taking it to the track all that much, prolly like 3 or 4 times a year. i dunno if 400 is too much for the street, because in chorpus christi they open up an air strip for people to race on. so thats the only track type thing il be on.

**Found the other list** What axles do you suggest I get?

[kornflakes28546]

i see a lot of off prices but just remember, with cars, everything will ALWAYS cost more, and take more time to do than expected. that phrase has never proved me wrong yet

[KaMaKaZiPyRo]

true, i know this is gunna be a while, but its just a long-term project.

[civickiller]

if your under 400whp with a crvtec at 28psi. i dont know what to say to you.

you listed cams and flywheel twice. why are you going with a 8 cr, thats way too low. go with 9 cr. those raxle axles probably wont last to the power you plan on putting down. if you plan on running multiple psi levels, you dont need cam gears because one setting wont be the same setting for lower psi. aebs are expensive sleeves, go with benson sleeves cheaper and just as good. you never listed a intake mani or tb.

[KaMaKaZiPyRo]

ya, my list isnt all the way done, this is the older one, i lost , my updated one, I plan on going with a jg or the type r manifold, and the gsr tb. ya i just thought 28psi because ive seen people barely hitting 450 with 28psi. i dunno if I said it but the hp goal was to the wheels. also i figured thats prolly waay too much for the street, and i know im prolly gunna be fixing it more than driving it. so i figured watever 15-20psi gets me on that sc60 turbo. i wanna just keep it at one psi level just to kill most of the confusion. also on the other list i had 9:1 cp pistons, cuz i read 8:1 was way too low.

[civickiller]

300whp is pretty much the limit on street tires, and you could run that much hp on your stock block

[turboEKhatch]

Don't fuck around with a B20 block. LS blocks are cheaper and more plentiful in the JY's, and B20 blocks use a different sleeve design that makes them inherently weaker. Run a GSR or ITR/B16 trans long before a B18B trans.

[civickiller]

yup ls blocks are more plentiful than b20 blocks i own 2 ls blocks, and the only difference is a bigger bore and a vtec oil pump.

if you end up going with the crvtec, a gsr or b16 trans would be a perfect trans for that

[KaMaKaZiPyRo]

ok, well i wanted to go with the crvtec because of torque, and my best friends getting an ls/vtec. i just wanted to know if it mattered what OBD the head is. I know the car would be obd1, the block obd2 and the head is obd0, how would I go about hooking all this up, also which ecu should I go with? and since im only gunna go for about 300-350hp what would I need to do to the internals, just to make sure, im relseeving no matter what just for backup.

[civickiller]

it dpends on your engine management. if you want to go hondata, uberdata. then you need to go obd1. idk how well a obd0 head will fit a obd1 dist.

it also depends on the build of hte motor and how high you plan on revving. since your resleeving, i think you can spend alittle extra on rods. i would suggest pauter rods, and cp pistons. since you plan on getting cams, you will need full valvetrain to go with it.

if you do get a good sized turbo, with a crvtec and cams you should reach 350whp with low boost.

[Kven]

the distributors should be interchangable. just match the distributor obd to the ecu obd. i suggest going with obd1 because they have pretty good ecu's for those years..

LS = B20

The reason the B20 makes more torque than the LS is because it's an 84MM bore, and the LS is an 81MM bore. If you have an LS sleeved and bored to 84MM, it's functionally identical to a B20.

For 350 HP you don't need to sleeve it. My car makes a little over 300 WHP at 14 pounds of boost, and I'm on a totally stock LS motor, it's my daily driver. I have several friends pushing over 400 WHP on LS, GSR, and a B16 block with new pistons and rods in stock sleeves. Detonation is what kills sleeves, not horsepower.

[KaMaKaZiPyRo]

so a sleeved b20 is more lickely to crack before a sleeved ls motor? also what ecu should i use? the p61, the p72, or a different one? o ya and what all could i use to get traction?

[Kven]

no, if theyre both sleeve then they should hold up just as well as the other. for the ecu, which OBD do you want? but of the ones you listed, and are going to tune it, go for the P61. the P72 should be identical except that it has IAB control(you dont need it unless you want to use a intake manifold with that function).

[Kven]

oh and for traction, get a gearbox with a stock LSD(the Type-R's) or a Quaife aftermarket LSD. if you drag then a clutch-type LSD will work(ATS, Cusco, etc.). Stay away from differential "modifiers" like the Phantom Grip. also pick a set of good tires. www.tirerack.com has reviews of the tires and that will help make your decision. also if you use Uberdata(i dont know if Hondata has this), but there's a feature called Full Throttle Launch. It lets you floor it but keeps the rpm at a preset level(ie 5000rpm). a good suspension will also help you grip.
