Why do the early SVO's have 175hp and the laters have 200?

[KenneBell]

Is it only the computer that is different? I have an 85 SVO engine with 175hp I believe, should I invest in an 86 SVO computer or keep my stock computer, just turn up the boost with a manual boost controller and advance the timing a little?

One last question, which intake is better for the SVO I have the really wide one on the car now but also have in storage the intake that has the intakes stacked like a four barrel. Thanks guys!!!

www.svoca.com should answer all your questions but a brief one is that the engine received better stuff later on. better ecu with larger injectors, redesigned intake manifold, etc, etc.

84 svos had 30lb injectors and a different ecu. (not sure what model) all thats different is fuel and timming curves

Don't waste your money on the later PE ecu...they bring 200-300 bux and just aren't worth it. If you want to get your car to the later specs with larger injectors and such, pick up an ecu from an 87-88 turbo coupe. If you just want to make 200hp, just turn up the boost to 18psi and get a K&N cone filter...
