Yeah, I'm running a 4agze fairly well modified (14 lbs. boost) and I'm sure I'm still good bit shy of 200... but there isn't a prayer of getting that kind of power out of a 4age without spending Crazy Big money. I'm not sure dumping $6-10K into the motor would get you even remotely close to what you're talking about honestly. You'd really need a formula atlantic racing series built 4age for that horsepower, and that is not a street friendly motor, nor is it remotely affordable. If you want N/A power, swap in the 20 valve blacktop (more horsepower and torque over stock, but fewer upgrade parts available, especially in the US)... or just mess with the suspension as was mentioned before and really learn to drive this car to its limits with the engine you've got. Once you REALLY learn the car well you shouldn't have any trouble pushing the car to its limits with the motor that is in there now. My Supercharged car has enough throttle to break loose mid turn and spin me if I push it super hard through a turn... the N/A will run to the ragged edge and not break free though. If you really want more power, buy another car made to go in a straight line or get a mk2 turbo (or swap in a mk2 turbo motor)... or get adventuresome and cram a v6 back there in the mk1.

I love my 4agze, for what its worth... I came from a 463rwhp 472rwtq Corvette LPE Grand Sport to my 88 N/A car and wasn't dissapointed at all once I learned how to drive the car properly. When I bought the S/C car summer before last, I knew I had found my dream car... much more fun than that 396 supercharged Vette was, and sooooooooo much more reliable!!! Oh, and it is more comfortable and gets about 10 more MPG even with me driving the car pretty hard. My S/C car is really quick for what it is... but the N/A isn't too much slower and there is nothing that sounds quite like a 4age running at 7,000 RPM's... mmmm. If you want to really wake up that 4age that is in there now, get a high flow muffler and match that with a conical K&N filter (or similar) and you'll notice a fairly nice change. My 88 N/A really woke up when I did those two things and added a better coil. Runs like a champ and I've had zero problems out of the car since I had the timing belt changed when I first got the car. If you do much more than that... you'll most likely want to go into the bottom end to replace bearings and such. When I rebuild my 4age I have a race-prepped head already waiting with a 3-angle valve job I'll be matching up with a set of cams, cam gears, a header and maybe a few other small things. I'm hopeing for 4agze type numbers from that build, but we'll see. I'm anxious to see how much the head will do for me horsepower wise. Best of luck with whatever you decide to do... I like the 89's
