I have an em1 with a b18b1 motor with a gsr trans im looking for a ~350 whp DD build. I have a b16 ecu/harness and was told i should run an obd1 ls ecu or p28 if someone could tell me what exactly that will entitle for me I would appreciate it

Now for the main things so far I have
An Hx35 56 mm turbo
greddy intercooler
greddy bov
38mm tial waste gate
stainless steel inline pro manifold
skunk 2 3inch exhaust
aem fuel rail
greddy turbo timer
garret boost gauge
walbro 255 fuel pump

what im looking into buying
stage 2 competition clutch kit
supertech valves,springs,retainers,seals
camshafts?
skunk2 pro series cam gears
arp head studs
3mm head gasket or should i run stock?
aem wide band
custom 2.5" piping
fluidyne or mishimoto radiator
1000cc injectors
a less restrictive intake mani skunk 2?
a bigger throttle body
new axels?

thoughts suggestions on what i need/won't need
do i even need to touch my bottom end?
Any feed back is appreciated.

 

the b16 ecu wont do you any good mainly because you dont have a vtec head and or a vtec engine. the obd1 ls ecu or a chipped p28 is the route i would take if i were you

run a stock head gasket
skunk2 IM would work
i dont think you need cam shafts stock should be fine

do a compression test to see where your at on compression

 

If you already have the b16 ecu and it's obd1 then you can use that otherwise will need jumper harness and an obd1 ecu.

Either way they need to be socketed and tuned one software like Neptune and hondata

 

alright well that solves ecu issue thanks guys.
so as far as new axels would stock ones be able to handle 350whp?
and as far as piston rings stock should be fine?
is there anything else i have listed seem a bit unnecessary for what im trying to accomplish?

 

OP
not to be rude, but have you spent any time finding the answers to these common questions?

 

X2

 

I wouldn't sugguest 350whp on a stock motor unless you had a bigger laggy turbo running lower boost and e85.

BUT if you insist on it doing so with a medium frame turbo...

 

@justYncredible
Is that not what I am doing right now? Asking people for answers; And I have been asking friends/tuners/strangers, I'm just getting multiple opinions because I'm fairly new to this and want to do it the right way or not at all.

 

@Charlie
does 300whp seem like a more reasonable number considering the size of my turbo?

 

That's not research, that's just asking people for the answer. Honda-tech is not the teachers edition

 

300whp on a stock LS bottom end will last longer. A healthy stock ls bottom end on ethanol will yeild more reliable power output but if sticking with pump gas keep it around 300. the ringlands on the pistons are weak and wont hold up as long with higher hp levels on pump gas. Thats from my experience anyhow

 

 

for any LS, I would tell people to enjoy it at 250-275whp range and save money for parts on rebuilding new block.

With a bigger turbo like 6262 (nice manifold(s) you can get 380-400whp on e85 but that pushing it on stock motor.

This is my buddies bone stock LS turbo on a 60trim turbo + crome + e85
Motor pulled strong for like 3 year daily driven.



This is another good buddies LS turbo (9.1cr + eagle rods) rocket snapfit valvesprings
crower st2 turbo cams + ramhorn manifold + skunk2 IM + 93octane.
This is his break in tune..... down the road he turned up the boost at made 390whp.




hope that helps a little.

 

One thing i didn't see on your list is a map sensor. I'm using the hondata/omni 4 bar. It will bolt in stock location. I was very happy with it. Also wouldn't be a bad idea to get some good engine mounts, and lsd.
