That right there is right about $2330.. and I still need an Alternator. I had several parts laying around too..Oil Press Sensor, Cam Sensor, GM Yellow Springs.
Yea it's more than the $1500 mark..if I went with a 5.3l that was $400 like mentioned above I'd be lower..but I went with the LS1 and I took some time to give it an over-haul and beef it up.
My individual parts cost is alot lower than the prices that you guys were throwing up tho..that's the point I'm tryin to make.
back to the OP - the reason this feels expensive is that our cars aren't worth much as much as LS cars. but if you've got cash in your motor and it's built setup, the 24x is a lot more reasonable than a conversion in my opinion.
if your motor is on it's last leg, then maybe the conversion is right for you, but don't underestimate all the small things that will add to the cost, that's all.
I purchased a LM7, 67k miles, with 4l60e, complete wire harness(including fuse/relay box and body harness), coils, PCM, all accessories, cooling system, most of the fuel system for...... $1200. Granted this is going into my 88 Silverado, I did the 24x to my car, the LT1 is going nowhere now!
I used to say I'd jump ship if I had a failure, but at this point I don't care in dropping 60 lbs. in block weight or whatever the weight loss is.
I honestly cant thank Mike enough for the incredible kit he's put together. Truely perfect!
The Best V8 Stories One Small Block at Time
What i have into mine: I bought a used kit off a member on this site that parted out his build. Payed $800 shipped. Included PCM, PCM Tray, Coils, DIY Coil Brackets, MSD Custom Wires, Boot Protectors, DIY Wiring Harness for 96 Auto car, and the 24x compenents from EFI. Since then its cost me $70 (Us-Canada shipping!) for 97 Timing Cover, and $75 for Mint 94 Wiring Harness (Reworked for Emissions, Model Year, and T56). So i have about 950 into my kit so far. All i need is a knock sensor and a hub replacement for my ATI Damper which is $$$ but well worth the added cash vs a stock hub and balancer. So at the most ill have $1100 into.
What does this get me vs a delco? Ive always had issues with my car it has 230k and ive replaced and diagnosed ign switchs, coils, icm, wiring, opti's,wires, plugs, etc. Just couldnt get a RELIABLE ignition system and its left me stranded countless times and the stress and time diagnosing these issues is enought to turn alot of people off. This setup totally deletes the opti and the troublesome issues and gives you alot more options for tuning and likely better running engine. So for what it costs for two new optis over the span of say 5-10 yrs i would rather spend the money now and have to worry less and enjoy my car more! While getting that out of it you can get peice of mind and trust your car to go anywhere specially long distances at a time. Love it or hate it aint for everybody but when youve invested alot of time and money into your car and have countless bad encounters you will not blink to do this swap!
After switching:
3 coils
4 ICM
2 computers, 4 tunes
2 DIFFERENT ENGINE COMBINAIONS (completely different blocks and valve train)
3 sets of lifters
2 engine harness'
3 sets of plug wires
mulitiple sets of plugs at different gaps
4 optisparks
2 sets of injectors
3 crank sensors
2 MAF sensors, 3 throttle bodies with different sensors
OBDI conversion
different knock sensors
I have given up, Mattsapp went through the same issues and went 24x and the miss was gone. Im not Saying it will fix mine but it willl eliminate a bunch more things for me.
I was lucky after selling a 6AL and a mallory 685 box, a bad MSD opti, a good MSD opti, and returning my new Delco opti I had more then enough money to do the conversion and buy a MSD timing twister for it. Infact I still have money left over.
Honestly IF this conversion fixes my top end miss Ill regret not going to it sooner. I mean look at the money I spent trying to diagnose it.
The question is should everyone just jump on the band wagon? Answer is no... there is alot of people that have had zero issues with there ignition system but for the people that do and just cant catch a break im willing to splurge a little bit rather then part my car for an ls swap or car outright. Ive come close a couple times but in the end i love the car i just want it reliable and if it cost me 800-1000 to do so im willing to bite the bullet rather then do the new trend which is LS ******* everything. My old mans 95 t/a for example has about 120k is still rocking the stock opti with the adition of a msd cap and rotor kit. Its been pissed on 2 or 3 times and even when it was spitting up coolant soon as she dried its 100% just a freak and pisses me right the **** off but it is what it is. I love the LT1 and its becoming a dying breed and is very overlooked as ive suprised a tone of people on the street and mine is mild compared to alot of the cars on this site!
Plus it's getting harder and harder to find anyone in my area who can/will even tune LTx stuff anymore and everyone can tune the LSx stuff. This was one of the major reasons I switched.
Finally if I want an LSx powered car I'll just buy one and mod it instead of swapping all my LTx stuff out, but that's my .02 cents.
Yes. I had a bad fuel pressure regulator(leaking). I love how I chased my *** on here for over a year and not one person suggested it, even with all the data logs I displayed with the motor constantly pulling fuel, the hard starts with extended cranking, etc..... Took til it burst completely and filled the cylinders completely with fuel before it was resolved, hell even with that info that I was now flooding the motor no one here brought up the regulator.....
Someone on EFI Live's forum caught it pretty quickly though when I posted up about it.

Once it was running correctly the tuner had it running in top shape in about a half hour.
