Turbo's make torque - torque moves cars.shinzen said:I kinda figure screw it. I have seen some 260-280hp n/a integras, and they will whup the hell out of the 300+hp turbos in drivability so why not with our cars.
did they put it on a mill to do that or throw it on a lapping table?MPNick said:Here is the cylinder head being resurfaced. It took .005 to get it flat. We did a mild port and polish on the ports and chambers.
Thanks again
Later..........Nick

The head and block is cut on a over head milling machine. It is a Van Norman MG3000. It has the CBN cutting toolbits. You get a very smooth finish [RA] on the surface when you are done. Most of the older system that some shops still use will not meet the right [RA] finish for the MLS gasket used in todays engines.RyanJayG said:did they put it on a mill to do that or throw it on a lapping table?
We have a few things we will try as we move along this race season. For now the idea is how far we can push the MSP with lots of boost along with good pistons and rods. Also the most inportant thing is tuning with the MPI. We spent alot of time on the porting stand. I now we made gains there. Before we bolt on things like bigger valves, camshafts, bigger turbo and other things. We what to see where we hit the wall.igdrasil said:Are you working on the Throttle Body and/or the intake manifold or leaving it stock?
A gas engine is a hot air pump. The more air and cooler air temps you can get into and out of the engine the more power you should make if you can keep the AFR spot on. In the past porting and polishing has always made more lowend torque on any turbo engine we built. Total max hp did not always go up because total air flow was still limited to the flow of the turbo. Take the max CFM flow of the turbo within its sweet zone and then multiply it by.7 and you will find your max power. This is good formula that has always worked for us.MP3skaterNC said:so you think the manifold and spipe porting are going to show some gains? ive got mine just laying around right now and the porting might not be a bad idea.
