example?

 

youll find a lotof built SOHC's at turbod16.com making more than 300whp without spray.

 

To make a reliable 250-300 WHP you'll need the following:

1. Forged rods, pistons and a good set of rings.
2. Good flowing manifold.
3. Free flowing exhaust system - 2.5" to 3".
4. T3 turbo - at least A/R .48/.60.
5. Larger injectors - DSM 450cc (because they are cheap and easy to get).
6. Walbro 255 LPH fuel pump - to make sure you have sufficient fuel when needed.
7. A 2.5 or a 3 bar map sensor.
8. Some will suggest reinforcing the block by adding aftermarket sleeves or filling the block or
block posting or a block guard (there are good and bad views about the block guard).
9. Some will suggest porting the head and a getting a 3 or 4 or 5 angle valve job.
10. Colder spark plugs - stick with NGK.

TUNING IS VERY, VERY IMPORTANT.

Search the forum and you will find most of the items listed above - very good quality and very good prices.

YOU ARE A LAZY *** NOOB . YOUR QUESTIONS HAVE BEEN ANSWERED MANY TIMES BEFORE. SEARCH BEFORE YOU ASK THE NEXT ONE .

 

drunkinmaster needs to watch what he is sayin there are people hitting over 500 hp with the sohc so think before typen plus it easy to hit 250 to 300 hp with a sohc. if money grows on tree for you.. you can do it

 

You also need to upgrade your clutch and pressure plate, and you need an engine management system (eg Uberdata) to control air/fuel mixture, timing, etc.

 

i never said that it be impossable to hit 300 hp reliably, like i said you need to do alot to achieve that goal. you cant just slap a turbo on and have 300 hp out of a sohc. there alot involved just like stanB said.
you are talking out of your ***. id like you to show me a 500 reliable hp sohc d motor.

 

How about 554 hp? Get this, the tuner sounds liked it was his only car and daily driven! Here's the link http://www.honda-tech.com/zerothread?id=1345861 and you'll see the that car.
Does it cost money yeah but it also costs to switch over to dohc so why not turbo this awesome power
from this great motor. Also, reliability comes from tune and how much abuse will this motor see
daily.
