This is going to be a long read... For any long-timers here in DFW that might know the car, I bought it from Jeff Komasko. T-Top GN, Jeff had added GNX clone pieces but no fender flares. 7 years ago, I commissioned turbo-guru Bill Duke to build the powertrain for this car. Very soon after, I was...

Ck out the latest GM High Tech perf. mag story on Race Jace.. Congratulations Jason :smile:

I'm not meaning to ruffle anyone's feathers here, but that bird may have already flown anyway. How many here have lost/damaged a motor from an alcohol injection system failure/or run the system out of alcohol? Nothing is perfect, and I'm already onboard with a system. I just want to fully...

Precision 51 turbo. Worked perfectly when I took it off the car last year to build new motor w/bigger turbo. $500 firm.

Has anyone used the M/T drag radial in the 275/55/16 size on an 8" rim?

Hey folks, Installing an alcohol kit soon. I need not tell you all of the $$$ invested in these engines. It appears that the SMC kit and Razor's are equally good. To be honest, delivery time will be the deciding factor. SMC seems to be at least a month behind at the moment.. At any rate, I...

Now that M&H and Mickey Thompson are making DR's we have more choices. I have Nittos on the Corvette and they work well as a street tire. I'm looking for a good hooking street tire, have slicks for the track. I went thru a set of ET Streets in about 100 mi, and they make the car handle like a...

Am installing a new 400 turbo w/manual valve body and brake. This car sees limited street and strip. Not worried about the lack of O/D, gas milage, etc. Car has the hardware to run mid/low 10's (see sig below), but it's doubtful that it will be thrashed hard enough at the track to see low 10's...

Lunched yet another converter, and likely the 2004r (again) Seriously considering a 400 w/a brake/3800 stall non-lock-up. My car sees limited street use, not really concerned about gas milage. For those that have made the conversion to a 400, any downsides or latent problems? Converter...

I understand the danger of debris from a broken trans getting into the converter. Is the opposite of the same concern? Started feeling a driveline vibration only on decel and some shudder as I would come to a stop, and recognized it as a possible converter failure. Not far from the house, clouds...

Does anyone know where I can get the graphite 3 bolt turbo flange gaskets? (Riviera?) I was getting them thru Ramchargers, and they no longer stock them. Thanks

Anyone know the Isky part# for the springs that rate 150# open, such as Nick recommends for rollers? Are they the 235-D blue stripe? Thanks

For those using or considering stacked steel headgaskets such as RJC sells, a bit of advice to avoid a major problem. After my total rebuild, my car would oil smoke badly, especially after accelleration, then idle, as well as drip from the breathers.. Went thru all of the usual suspects...

I work with a fellow that is a 23 yr GM tech, Calloway certified, etc. It is his opinion that our cars could run much better in cruise/street mode with much more timing than most of the chip burners use. As he puts it, the timing tables for our cars seem to be burned for WOT/high boost...

How many have converted to a blow-thru MAF setup? Just did this, and have not had a chance to test. What I am curious about are any appreciable changes in the tune up. I realize that now the MAF is seeing heated air...

My car has been smoking at idle w/new eng. 210/210 billet roller w/LT-1 springs. The spring dampers were catching the PC seals and lifting them off the guides. Can I run this spring w/out the damper? It would seem the damper doesn't do much, I can completely collapse it between my fingers...

Translator Code 42/spool/street fuel/ET Streets Been chasing a couple of big problems, got them solved and wanted to report back as to the solutions. Also, thank everyone for their valuable input. First and worst was the intermittant problem of setting code 42/car would barely run. Replaced...

Upsized turbo (TE66), trouble getting more than 5-7# on launch w/the 3200 stall. Have no problem w/having the converter re-stalled to 3800. Anyone running this high of a stall on the street, and are you having any issues? I have heard it suggested that it may take too much rpm just to get the...

I replaced a TE51/009's w/a John Craig TE66/72# this year. The car has a 3200 stall converter, chips by Eric @ TurboTweak. Pls see my sig for the rest of the mods. I was able to get 15# launches with the 51, and only able to get 5-7# w/the 66. As soon as the car gets rolling a bit, spools right...

MT has recently released this tire for the DOT classes. Just wondered if anyone else has tried them yet. I have a pair coming tomorrow, and will post my evaluation. I run ET Drags at the track, I just needed something to try to hook on the street, and didn't want to pull my slicks off the 15"...
