Ok, I have set my power goal for my 7a at 200 hp at the wheels.
Now the question is, how? The obvious answer from most is 'slap on a turbo.' but that's not what I want to hear. I am going to re-build my engine soon. Here is my plan: Re-build enging to brand ,new stock condition + a 1.8-2.0mm head gasket to lower compression a hair. Then, underdrive pully, and retard the timing a hair with adjustable cam gears for a 'rolla. Turbocharger +large FMIC and about ten pounds of boost.(maybe up to 14psi). I have also thought about calling up jet and having the rev-limiter on my car raised up to 6500-6800. What do you guys think about that? So, with proper tuning and electronics, what kind of power output do yall think I'd get? I have seen turbo 7a's pulling 170ish, So I have high hopes. keep in mind I am thinking outloud here so... Thanks for reading. Jon |

fuel pump i reccomd is a walbro 255lph unit... i recently learned theres 2 versions out there but im not positive on the differences... either way u get a good pump for under 100 shipped. i was told 4ag pistons will fit, so u need custom rods. call different companys and see what they can do.. yes i called, its expensive and the usually want a deposit.. boost is expensive period. custom pistons are the same.. expensive but call around, theres companys that will do it. the smoking caused underboost is a problem that is made or fixed by different things... my 7a smoked a little due to a oil return problem... simple fixed by making sure it was shorter to increase oil flow back to the oil pan smoother....2nd was my PCV system.. under non-boost conditions the stock motor was only vacuum, causing -pressure in the crank at all times, but underboost the pvc would lock which is good, but the other hose to the right would let pressure through to the crankcase makeing positive pressure there, and also causing the pcv valve itself to fail.... causing hell to the motor... liquids do not compress so u can at wose get bent valves in the head..im sure more can happen... i found on the internet a PCV that can withstand 130psi without failure, and is dyno proven (4hp more) to give the pistonrings a better seal. i posted it before in celica.net with no opinions, bought it but the motor blewup before i got to try it.. i still look at it to be my "holy grail" to my PCV problems... btw: once oil is coming out of the valve cover, where the pcv or breather is, its too late. new pistons,rings, landrings will be needed.
