Started dismantling Trans-Am engine
- Thread starter TransAmDan
- Start date
I aim to change the oil before the weekend, depending on weather. Will take a look for any potential exhaust knocking areas too.
Some of my HT leads have shown signs of melting. The lead gets fairly close to the header wrapped exhaust. Part of the issue if the leads were made up locally, and the angle it some off the coil pack is different by about 15 degrees.
Two ways to sort the issue.
1. Spark plug sleeves to protect from the heat.
This arrived today, it's 1 meter long. Thinking of cutting it to 8 equal lengths, and rolling over the ends to reduce fraying. This should protect the plug wires.
2. Purchase other HT leads.
LS1/LS6 Grantelli Motor Sports Coil On Plug Wires (Solid Core) - w/Red High Temp Sleeved Cable & Black Fire Sleeve
These Granatelli's coil on plug connectors are designed to help improve gas mileage and throttle response. They help improve spark with 0 ohms of resistance and no radio interference. These are direct OEM replacements, and won't void your factory warranty.
I'm sure these suckers won't melt. Looks the bollox. Drawback is $182 price tag.
I'll see how option 1 pans out.

I'd go with the Granatelli's option based on experience.
They do look nice, I keep going back to them and drooling over the picture.
If I order the leads, I will be getting some new coil packs too. MSD made themselves known for ignition stuff. My coil packs have done over 180k miles, how many times have the fired, lol. Well although no signs of then being at fault. Its probably time for a fresh set. $600
MSD Ignition's Multiple Spark Coils (MSC) will fit in place of the stock GM LS coils and connect directly to the factory connectors. Once installed, you'll have the power and performance of higher energy sparks, crowned with MSD's multiple spark discharge. Increased spark energy and voltage, along with multiple spark capabilities, help improve the combustion process of the fuel mixture to create an efficient burn. This results in improved throttle response, smooth idle and quick starts, plus increased high rpm performance!
Fuel injectors are 42lb/hr @ 43 PSI, so almost 60lb/hr at fuel rail pressure, this should be good enough for all the power I can produce from this engine. However they are around 10 years old now. Perhaps time for a new set of flow matched ones...
$400 for a new set. I'm happy with racetronics, and happy to use them same again, and perhaps go a little bigger.
98-02 LS1 Racetronix High-Z Siemens FLow Macthed Fuel Injectors - 63 lb/hr @ 43 psi.
Dynamically flowed and grouped to within 1% tolerance using Racetronix custom injector flow bench when purchased in packs. All tests run with n-Heptane @ 20oC (+/-1oC), 3.0 Bar (+/-0.01 Bar), 14VDC (+/-0.05VDC), saturated driver with RC cutoff.
Injector flow rates are based on testing with n-Heptane test solvent (0.6855 g/ml). U.S. EPA emission test gasoline 40CFR86.113 (0.735g/ml) flows in most common injector designs at about a 3 to 4% higher rate than n-Heptane. A ratio of 1.035:1 can be used when converting the flow specifications above.
This high-impedance injector will work with all factory ECM/PCM injector drivers.

Strength of the pound against the dollar is going the right direction too. $1.302 to a quid. Which is a whole lot better than $1.17 to a quid back in October. If only it was the end of July in 2014, it was $1.71 to a £.
Had some success on gold yesterday, 4 more sessions like that, I could buy the coils/wires and injectors.
