is p28 better then like b16 or b18 ecu? don't that p28 have to be chipped?

Mfoehrkolb

obd1 p28 with step down (deping on your car year). will plug and play. If you look up ls.vtec builds, they say the b series vtec stock ecu tends to give the car a rouge idle, and some other minor problems and if you get p28 obd1, you can get it chipped as well. Me and all my friends use p28's on the ls.vtec builds and always worked wonders.

mcyang87

ahhh i see...it a good thing p28 is obd1 cause i have a 94 integra :D

K2sInteg98

yup, you will just have to get it chipped and tuned for your car because a p28 is a single cam vtec ecu, you need it to be tuned to your dohc vtec

--- Yeah, Mcyang87. Don't misconstrue what im saying. You will still need to get it chipped, just p28 runs better till you do.

mcyang87

alright i remember to get it chipped thanks

if you build an ls-vetc make sure you build it the right way!
Don't do a half *** job as you said that you don't have enough funds to build. Trust me if you don't build it right from the beginning it will cost you more later on! Better be patient and save up to do the build.
If you purchase the golden eagle kit, ditch the gasket and purchase an OEM LS
Make sure you get ARP rod bolts and Head studs, new oil pump, water pump 22t and timing belt, then you'll need a good tune on a P28

mcyang87

is the golden eagle head gasket that bad then to OEM LS?

R.A.T.

It's not bad, it's just not the right one. The one they supply you with is for a vtec engine. Your block is still the LS so you must get the OEM LS Gasket or else it will leak.

mcyang87

ahh i see...so im better off buying the head bolt, stud, conversion kit without the headgasket then

mcyang87

i visit some of the website that has ls/vtec conversion kit..they ask if it 81mm bore which is stock ls block would that work too?

NAmodified

so if i go with a lsv set up and i change all the internals to itr!!! i will have a type r with a bigger displacement correct?

also i heard a golden eagle kit will have a greater vtec kick due to the fact that there is more pressure and oil going to the head.

compared to the small oil hole on the block that is used for vtec

mcyang87

well the internal that im getting with the head is already been done by Skunk2...ahhh so the golden eagle kit is pretty good then

Not too sure about the bigger displacement, maybe more compression but if you stick to stock bores your displacement will be the same.
Someone correct me if I'm wrong on this one.
And about more pressure... alot of people add catch cans and engine breathers to release the pressure. Pressure can damage equipment prematurely.

mcyang87

ahh i c

the bore isn't the only factor in discplacement size. your the length of your connecting rods, your crank, your pistons all have a factor. the LS's displcament is the largest out of the b18c5 and c1. it has the longest stroke and lowest comp pistons. so it has like 75cc more.

mcyang87

so when i go to order the ls/vtec conversion kit...do i put down 81mm bore or 82mm bore?

Mfoehrkolb

81 bore LS head gasket.

R.A.T.

Thanks for clearing that up. But what would be the point to change all the internals if you go LS/Vtec? Might as well just do a ITR swap. The LS/Vtec is stronger on the low end with it's rod length making quicker than an ITR and GSR.

mcyang87

ahhh i guess ls/vtec has it up and down then

mcyang87

which head is better to fun ls/vtec? GSR or B16 head?

Follow that link. There's a good explanation on the pros and cons to both under "The Head". I would personally go with the b16 head but that's me.

mcyang87

alright i head b16 head i give you a better top end is that correct?

mcyang87

i was thinking would a type r head be better then b16 head?
