Alex,
It would take some effort to get an SR to live long at that output.
The weak points are rods, oiling system, head flow. The bottom end
prep would be critical and the head would need work to get good flow
even with lots of boost. Tuning would have to be spot on, they don't
like detonation or overheating at all. What is your budget? An "all
stock" ITA engine is around $4500 with a good core.
Get that car to hook, and you're looking at 9 sec 1/4 mi times. Super sleeper.
"all stock" ITA engines have the following parameters:
Yep, it's a non-turbo. We are allowed the following
mods (and we've done them all):
- Built within service limits
- balanced and blueprinted
- .040" overbore
- +1/2 point compression
- exhaust is free (we run a HotShot Gen 6 with
ultraFlo muffler)
- intake is free outside the throttle body (we run a
CAI)
- stock flywheel
- stock cams
- stock valves
- no porting and polishing
- ECU is free, but we're running stock.
We put out 147hp to the wheels on a DynaPack, which
would be about 155 on a DynoJet; that's *about* 180 hp
at the crank at 6800 RPM. The key is careful prep and
optimizing specs...
So, the ITA motor is not really "stock" as such, but it complies to the ITA rules. And, that's a really healthy output for an SR without a turbo. Hell, 180hp was the original horsepower rating for the 82 280ZX Turbo! With a 2.8L six! Anyways, around this point, I fill the mechanic in. He's thinking, you know, get SR20 block, turbocharge it, and mostly pray that it holds together under abuse.
This is when I explain that I think the JUN 2.2L stroker (billet) crank, rods, and Cosworth pistons will be fine for the bottom end, and as for the top end, JUN also makes a complete SR20 cylinder head with proper massaging for the quench zones, their favorite cams, and a ceiling of like 10,000rpm. Those parts are about $10,000. Thank god Sandy isn't reading this, she'd have kittens.
I explained to the mechanic that it may seem insane to spend $15,000 on an engine that's going into a 25-year old car, just to relive my youth, but that the alternative is an M5 or SL65. Both great cars, don't get me wrong, but Thirty is right around the corner, and I am going to have an early mid-life crisis. With the amount of work that needs to be done to the chassis, that's probably a six to eight month job, depending on how many friends help me out. We gotta do all the suspension, the interior, fab up a dash, defi-ize it, and do aero on it. I'm going to be the guy driving an Imola Red (this is a Ferrari color, for the car-impaired) 280ZX with a 3' double-plane wing with gurney flaps, canards, skirts, and diffusers in a 5-point harness to work in the morning. I'm looking for 600 horse, hopefully to the wheel, but I'll settle for 600 at the crank. Maybe even 550. And by the time I'm done with the chassis, we should have the weight down to 2200lbs. And, the rate I'm losing weight, maybe the car will be finished for my thirtieth birthday, which is coming around in, what... eighteen months now? And I'll be a svelte 10% of my car's mass, positioned correctly in the center so as not to upset the all-important F/R weight distribution.
Yes, my friends. This will be a 9 second car. And it's gonna be street legal. It's going to be my thirtieth birthday present, to myself, and I hope to god I don't get arrested for setting the cruise control at 180mph on I-66. Low-flying aircraft, baby. Maybe I'll get rich when I publish Limits. Charlie says not likely, but maybe Sharks will do it. That one's certainly got movie potential.
