What was your setup making?

I won't know until I get the motor in the car...which will be sometime after chirstmas but before spring. The motor will make 250whp+ after a little twisting of Shad's arm. A clone of mine made 268whp...so we'll just have to see.

Bottom End
84mm 11.5:1 pistons I-Beam Forged Rods Knifed/Lightened/Nitrided/Balanced and Blueprinted Crank Ishihara-Johnson Windage System Top End B16 Head, enhanced in the quench pad area similar to a GSR, and fully machined. Competition Serdi Valve job, full de-shrouded to match 84mm bore. Mild porting - possibly professional CNC port work. Skunk2 Pro Series Springs/Retainers Skunk2 Pro2+ Cams Ferrea Hollow Stem Sodium Fill Valves. Other Golden Eagle LS/VTEC Conversion Kit. Skunk2 Composite Intake (when released) Large Tube Headers (1 5/8" Primaries with 2.5" collector, 4-1 design) No cat. Muffler for street use. Header extension for Drag use. 10,500 RPM - 11,000 RPM Mostly, this is being posted for Fabrik8 or other knowledgeable people to comment on, as to what they feel is a reasonable goal for said motor, what they like or don't like about the setup, and what they would do different. It's mostly so I can get some ideas on where I might look for improvements, and anyone who's truly interested and willing to make a suggestion is welcome to ask for additional details on any specific parts used (or planned) through PM. S200 or s300 would be a must also like stated above, unless you know a very very good chrome tuner. GOOD Luck with the build post some update threads when you get this thing running. |
Re: LS/VTEC Setup - Opinions
I too agree with others. You will need to bump the compression up to make the most out of those cams. I also agree with the boring of the sleeves you wont be save running 84mm. If you were turning the rpms you quoted in your first post then you would be getting big time side-wall loading from the pistons which would not be good for those thin sleeves. You probably wont make power anywhere close to that high of a rpm though.

On a side note...the ablity to run 10,000 - 11,000 will require some hefty springs to keep from floating a valve. The problem here is that the more spring...the more you will beat your valve seats to death. It's a game of "give and take". You can't have both. |

I do understand budgets...but the first thing you need to do is port the head...by a REAL porter, not some guy with a Dremel. Second, In making the head flow better, you need to start thinking about higher flowing headers, intake manifolds and throttlebodies. Then, after all this, get a good set of stage 2 type cams and upgrade your valvetrain. |

THIS IS WHERE YOU MAKE YOUR POWWWWWER! i had a ls/vtec setup in my crx and it made 205 whp and 143 ft/lbs. the main thing that was holding me back was i didnt want to turn the motor past 8500 rpms so i went with a smaller cam(edelbrock 4730) that made alot of midrange.(I drove the car daily) My head was ported and the bottom end was just punched 30 over with a set of wiesco 12:1's and eagle h-beams. I loved the setup! to this day i wish i would not have gotten rid of it:(. |
