I've been looking at all these wonderful setups and I'm thinking to myself, maybe I should sell myself short @ 400whp. I'm wondering if a fully built 2.0L B18B with say a SC61 is capable of 500whp w/o nitrous. NON-VTEC of course and must be able to run on pump gas.

If its possible I'm thinking of tryin for 500whp w/out nitrous and say 550whp with it(Just a small 50 or 75 shot).

 

describe your setup... fully built meaning sleeves, cams etc..??

 

you wouldnt want to run pump gas with 500whp and youd need a bb turbo to have a decent powerband.

 

With an intake manifold, cams, and valvetrain you will be able to make 500whp on a sc61. Providing, your bottum end will take. With methnal/ water injection you'll be able to do it on pump gas aswell.

 

Welll the setup I'll be running is as follows:

B18B sleeved and bored to 2.0L
Worked LS Crank(Stewart Racing Engines)
ARB Bolts Throughtout Whole Engine
ACL or Honda Bearings Thoughout
RS Machine Rods and Turbo Pistons
Worked LS Head w/ Crower 404s, Crower Springs/Retainers, and Ferrea Plus Size Valves
AIR or AEBS Intake Manifold
70mm TB

I figured that setup would get me there. Well if 500whp isn't achievable on pump gas with methanal/water injection should I just stick with 400-450whp?

 

B20 SC61 (t3 .63 a/r)

exactly what I was going to say.

F' running meth/alky. Just run race gas and up the boost. 500whp will be easy for that setup.

 

Why do you want to run n2o? You can definitely make 500HP with an SC-61. I would not push higher then 450 on pump, why risk it??? You can't use that power on the street.

 

You got E85 in your Area?

not necessarily true...plenty of guys run the SC61 on their setups and make great poewr with them....not to mention having a great powerband. Also since he's at a 2.0L,he will spool that SC61 sooner than a stock bore obviously...

eh, i guess its just personal preference. as seen in the dyno graph, he would only have about 2300rpms of boost on an sc61..

That dyno shuts off at 7300. An LS-headded motor with decent cams will hold power to 8000+ no problems.

Not to mention ball bearings don't do that much to speed up spoolup, they mainly help with transient response.

someone who knows something intelligent for a change. I'm so glad that people actually know why ball bearing turbos are used....its not all bandwagon

 

Well it looks like I may just shoot for 450whp on pump and up it to around 500-550 with race gas.

The reason for the nitrous is because I like the little extra umph it gives you. I'm still undecided if I'm even going to put it on.

So 450whp on pump sounds fun. Thanks for the help guys.

Not that I know of. Just Turbo Blue(110), Premium(93), and some Air Craft Fuel(180 maybe?).

 

b20 head/ls head- same thing. i doubt that dyno was running a stock head with that setup. a ball bearing turbo would start spooling prolly 600rpms or so sooner. and either way, you act like he wouldnt be better off with a bb turbo.. btw, im actually running a journal bearing turbo myself.
