I wasn't offended at all by our newbie's response because that's exactly what ran through my head when I first heard those numbers. All that work and engineering for something that I could have gotten out of a built small block (well, not really)? What did I do wrong? Then reason set in. You don't see that kind of power at mile high altitude on any normally aspirated car that doesn't ride on a trailer. Then I imagined myself trying to drive this thing on a track with 600+ RWHP--not a pretty sight. As I said, it squats so hard as it is that the exhaust pipes nearly touch the ground at takeoff and the tires really really rub, and that's with 250 lb per inch springs. I'll have to really sort things out back there to have a vehicle that doesn't squat so much and doesn't have massive oversteer with really stiff springs. I envision being able to crank the boost up for the occasional drag run (in case I run into a Supra) and turn it down for runs at the track. The turbos are modified Buick GN's (.63 on the turbine side and .42 on the compressor side) running less than 8 pounds of boost, so there's more there. For now, all I know is that it makes my FD3S seem really tame and I have yet to go even halfway with the throttle. Thanks for all your support and no hard feelings towards anyone! All you guys are great and have taught me a lot!

At my age (41) I'd seriously hurt myself with a backflip. It's true I'm somewhat happy. At this altitude, you don't see this much horsepower with a NA car. The shop owner told me that he has a high 10 second Nova with 400 RWHP, and his car weighs 1000 pounds more. Also, it makes my 93 RX7 feel slow and I have yet to floor it on the Z (it was getting dark driving the car home and I don't have working lights yet-didn't want the police to take notice). As for how much boost, I forgot to ask. That's how unsorted it is. Still a lot of work to be done, and somehow I'm more motivated now to work on the car.

Well, I got my car back from the shop. The dyno numbers were a little short of what I had hoped (450 RWHP , 500ft/lb RW torque). I'm told the cam is fairly mild and I can get about 150 hp more with a different bumpstick. The good new is that it's very streetable horsepower with mild boost. There's a lot more potential in the motor and I've decided to sort the car out some more rather than ask for more power right now. It squats real hard off the line, even with fairly stiff springs. Since this is to be a street/road course/autocross car, I'd better get the suspension better optimized before becoming more power hungry. Overall, I'm very happy with it and I'm glad to have it back in my shop.

Sounds similar to what I got. It was huge and snug fits right in front of the radiator, just like it was made for the car. If it even works 75% as efficiently as a similarly sized Spearco unit, I'll be happy. I had to modify the inlet and outlet also.

Did one of the responders say "it's gonna be one hot VULVA when it's done"?

I don't have a death wish. Actually, there is a website somewhere where a Dutch guy put a 13b turbo rotary motor on a go kart. I'm not sure if he is still alive.

The Suzuki Hyabusa motor in my basement kicks but over any Ferrari motor. I just have to find a car to put it in. Maybe a Lotus Super 7 clone? Imagine....190 hp at 12,000 RPM with a sequential shifter, in a car that weighs less than 1000 pounds.

Ditto that. I decided to do everything from scratch, made mistakes along the way, and ended up spending way more in the long run. I mean, my Electromotive system is great, but it was 3 grand! I coulda done better with an LS1 completely injected and built it up from there.

Funny story. I agree with MiKelly about the fact that Honduhs are practical and all these kids have. I was like that line a quarter of a century ago with my German Ricer, a VW GTI. It was actually peppy back then and I did what I could tafford to soup it up, but that kid's Civic would smoke it today. I think there's hope for the Honduh crowd though. They worship me when I drive the ultimate ricer car, my 93 RX7. I get comments all the time when I'm driving and Civics with fart pipes follow me to give me the thumbs up.

160 lb/hr injectors! Wow! And the under car placement of the turbos on that APS care is awesome. A real sleeper and much cooler underhood than a traditional setup.

Well, you know what they say....there's no replacement for displacement!

Apparently, the new radiator has arrived and is already in the car. That aluminum unit looks great though. As for the cowl hood, we decided to go deluxe with it and we have located a company that can make us a custom cowl fiberglass hood. It will take 3 weeks. As for the cost of the turbo setup, well I quit counting long ago because it gives me heartburn to think about it. The manifolds are simply modified Corvette LT1 units flipped over with a T3 turbo flange adapted to it. Fairly cheap and can be obtained off of EBAY for under $100. I tried to go budget on the turbos, they are Buick GN units that I obtained for $200 each on EBAY, and I put some Ford T3 housings on them (also cheaply obtained). I essentially had a T3/T4ish hybrid. Upon further inspection though, the turbos needed rebuilding at $600 each. If I were to do it again, I would get a real T3/T4 hybrid. It woulda cost less. The huge intercooler was bought from a company on EBAY out of Hong Kong for about $500 (Perfect fit) although I had to get the intake and outlet sides modified. Turbo hat cost $100. The inlet and outlet plumbing was not bad--mid hundreds for all of it including blowoff valves and external wastegates. Overall, not cheap, but it could have been a lot worse. Oh, I forgot the Electromotive fuel injection setup, which some think is essential for a turbo system-I don't want to tell you how much it all cost because it would be a sad reminder, but you can look it up. Then I had to upgrade the fuel system to feed this beast (huge fuel lines, huge fuel pump, etc). And so it spirals out of control.

Damn that's funny...I don't care who y'are....you can't make that stuff up

By the way Hanns, I feel so much better for you that you now have a certified cage in that beast. You'll be so much safer. Not!!!

It never rains in Colorado BTW, some of you are still able to post smilies on this forum. How do you do that with the current software we use on HybridZ? Actually, we have considered the option of putting the intakes through the firewall. Just wasn't sure how much room there was back there near the wiper motors , but we could put a couple of RamAir scoops near them. And yes, it will be a bitch changing the plugs. I would probably have to remove the turbos to make it an easy job. The downpipes conveniently separate in half to make turbo removal easy. As to the speed at which this is coming together, it's nice having the luxury of having the work done to the car while I'm at my day job. I decided that it would take a long time to get it done if I didn't farm out the completion of the work-I had been close to completing it for a couple of years now. It was kindof sad not turning every bolt on the car by myself, but most of the concept is mine and I think it's great having input from the pros at the shop .

Damn I like these new retro cars. Detroit has finally figured it out. I can't wait for the retro versions of the AMC Pacer and Gremlin. Now, them's some awesome cars! Maybe they can build it on a more modern platform like the Yugo.

No, but I've exploded a few short blocks.

You are welcome to come over and see it when it's done, as is anyone else (even those who haven't heard back from me by private e-mail, since I am terrible at checking my e-mail-my bad)

Thanks guys, every little bit of input helps. Otherwise, I'll find out what I should have done by sad experience. I was worried about the master cylinder issue, but I wasn't aware that anyone had ever nearly burned a hole in one. That would be a thrill ride I could skip. I'll revisit the radiator thing with my mechanic, because it sure will save me a lot over what they suggested.

That's easy. Just when I had my 383 stroker just about completed, I dropped a nut down the intake manifold (it was in the car at the time). HybridZ members gave all kinds of suggestions, but wouldn't ya know it, the bolt went down one of the only open intake valves into one of the cylinders. I took the suspected head off and took the bolt out. I tightened down the head and cranked the starter just for fun. I heard a thud of metal against metal. Just great I thought. I couldn't figure it out (clearance issue?), so I took the motor out of the car, tore it down, and found another nut in the opposite side of the engine! Same miraculous misdeed twice in the same engine!

Try a twin turbo in a V8 Z car! I salute you brother. In my quest for horsepower, I had so many versions of manifolds, intercooler plumbing, etc, that I lost count. Keep at it. It's a hard road, but I'm sure it will be worth it. Just ask Turbomeister (I fear for his life with all that power).

Well, it's coming along. The boys at the shop laughed at my welding skills (or lack of them) and cleaned up the plumbing of my turbo system. Looks much better now. They did keep the original concept, though. The photos below show the turbos hooked up as they will be when the car goes to the dyno (soon). The exhaust is being reworked as the original was only a mockup. It will be a single very large dual inlet muffler with a dual outlet that fits just behind the tranny. I'm told that when they started it up with just straight pipes, it was fairly quiet. That's what turbos are good for. The only major thing that needs to be ordered now is a new radiator. The one that was originally in the car was one from the Jags that Run folks and it's leaking. Oh well, it gives me the chance to order a (expensive!) aluminum radiator that has a snowball's chance in hell of cooling the car. We also need to figure out the location of the air intakes. Unlike most turbos, the exhaust downpipes head towards the front and the intake tubes go towards the back of the engine compartment. We will probably direct the tubes back and towards the middle of the engine bay. That means I'll need to put a cowl on the hood to get some cold air, which I didn't want to do because I wanted to keep the sleeper look. Oh well, everything is a compromise.
