b20v build in EK shell
I have a healthy b20b motor in a 91 crx si right now that I sadly have to junk because the undercarriage is rotted to s**t. The swap will be going into an ek shell which has a d16y8 in it for my DD. Once it's finished I am using it for mostly autox and I am aware that the b20 blocks is not the choice for that kind of thing but i already got plans for that if the block decides to blow. So here's what I'm planning to do with the build. Will be happy to make at least 200, 210whp or more.
B20b Block:
stock bore and unsleeved
CP high compression piston 11:5:1 or higher
Ls crankshaft ls/b20 rods
acl rod bearings
acl thrust bearing
toda light weight flywheel
hot tanked, assemble, and balanced
b16 head:
hot tanked
3 or 5 angle valve job maybe port and polish
supertech valves, springs, and retainers
toda spec A camshafts
toda cam pulleys
Skunk2 ultra street Intake manifold
skunk2 68mm or 70mm throttle body
OEM fuel rail with 440cc injectors
Transmission:
Plan on using a GSR LSD transmission
with exeddy stage 1 clutch
Suspension:
Koni Yellows with Ground control coilovers
ASR LCA
ASR subframe
Type r Swaybars
Skunk 2 front and rear camber kit
K tune traction bar
Rear disc brake conversion from 99 00 si
ECU:
p28 chipped
hondata s300
Other things i'm going to need for the build:
Golden eagle ls/b20vtec kit 84mm gasket
Vtec water and oil pump
Arp head studs
I am still researching for the best setup possible and this is some of the things i'm planning on doing. Will take any suggestions to my build and if I"m missing anything feel free to let me know. My wife and I is both throwing money into the build and will be racing at autox events and local tracks.

Re: b20v build in EK shell
I'd skip the eagle crank and rods myself.
Stock 89 crank, or 87mm if you want. ARP rod bolts on factory rods have been proven to be a solid setup.

Re: b20v build in EK shell
Depending on what kinda fuel you run you could go higher on compression.
Good call on the asr subframe brace. I'm a victim of subframe tearout even with the beaks kit. Shoulda got the asr.

Re: b20v build in EK shell
With everything you posted you should get about 200hp. Your going to want better brakes. So either get a aftermarket brake kit or just rob a integra or 99/00 SI rear disc and put on your EK. Esp if your going to do autox. Should be a good little build. If your looking into a software to tune your ECU and your using a OBD1 ecu (P28) I'd just use crome. It'll save you some money and will get you on where you want to be at.

Re: b20v build in EK shell
OK thanks. Save me some bucks there. I know arp rod bolts is a must.

I want to use 93 octane and that's good to know about Beaks subframe. I want to do everything right the first time around.

Re: b20v build in EK shell
I will definitely upgrade the brakes. Is 440cc injectors too much for my setup? I know a tuner not too far from me that everyone keeps telling me to go to for a tune. He tuned my friend`s h2b and it pulls hard. Stock internals with aftermarket headers, exhaust, and intake and got 220whp if I remember correctly.

Re: b20v build in EK shell
Skip the AEM fuel rail too. No need for it when a stock one will work just fine.
And by ARP "bolts", I assume you mean ARP head STUDS? Studs are better. RE-useable more times and less chances of damaging the block threads.
Ive never used Crome before, but it seems like it is not the best choice unless you are really on a tight budget and don't mind working through all the "bugs" Crome has. This is just what Ive read on here over the years. If you want a more "stable" tuning software, look into Neptune or Hondata. Ultimately your tuner is gonna be the one using it, so definitely talk to him personally.
Last bit of advice is make sure all your clearances are setup correctly. Triple check them. All the best parts in the world don't mean anything if you measure .001" off or a decimal point gets moved to the wrong spot. Good luck!

Re: b20v build in EK shell
I appreciate everyone's input on helping me with this build. If there's anything else on the list that I wouldn't need, I can use oem parts to save a little money (that won't effect the build performance wise), point it out to me so I can take it off my list. Also parts that I don't have listed. Again thank you all.

Re: b20v build in EK shell
op- if you are worried about the b20 block not being the best choice then get it css'd. not sure why you are set on stock bore but id bet it needs at least 84.25 to clean up any out of round that is there. i would just css (for your peace of mind its not much money overall) then go 84.5mm. some itr reps either rs or the ycp's and arp replacement rod studs in the oem rods will do the trick.

Re: b20v build in EK shell
And to add to the brake upgrade part, the 1 inch master cylinder from an Integra feels great. Pedal pressure and travel is really good in my opinion. You'll have to use the teggy booster as well and reflare 1 line if I remember correctly.

OK I'll drive my buddies dc2 and drive it just to get an idea of how it feels and if I like it I'll consider using the master cylinder from the teggy's.

Re: b20v build in EK shell
I'm starting to respect built Ls's and B20's more n more Lol. I'm still gaining ground on them but I'm also in a sub 3000lb car. GL on your build.
Wanted to add I personally like the S300 V3, I have a Ipod mounted with my tunes but at the same time I can keep Hondata app up keeping n eye on ECT, IAT, for norm sakes n failsafe sake. I like it more n more as I learn.
