Ok, with the new money I'll be making, its time to start modding

With as few as I see (if any at all), I've decided I'm gonna make the Z one of the few 93 LT4's around. I've already got a short list of parts so far, including...

95+ timing cover
95+ Opti harness
95+ Opti vacuum line
95+ LT4 Conversion kit (there's a kit now for the non-vented Opti LT1's as well now)
LT4 Extreme Duty timing set
Either an MSD or DynaSpark Opti (would love to do a Delteq or LTCC conversion, but I gotta worry about stupid CA smog laws)
SLP ceramic coated headers and install kit
Reprogram of my tune from PCMForLess

Anything else I should add in to that? Anything I should substitue? I know I've gotta replace the rails. Will I have any problems with the fuel lines mating up to the 94+ FPR? Any other problems I'm not considering? Thanks guys.

you don't have LT4 heads and intake

4th Item in the list...95+ LT4 Conversion Kit...this includes heads, intake, LT4 hot cam, 1.6 RRs, gaskets, etc.

I have a couple suggestions. BTW, have you received my texts lately? Been sending them the last week, but never a reply

30 lb injectors based on 80% duty cycle and a maximum of 425 fwhp.
52 mm throttle body
Poly motor mounts

And now for the fun stuff...
Forged pistons, crank, 4 bolt mains, etc. ... Or check the condition of your motor by a compression and leak down test. Last time I heard, it used a quart of oil after 3k. The tests would show ring condition, etc.
The last thing we need is a spun bearing or something that ruins the bottom end of the motor.

And a 12 bolt rear end.

Nope, haven't gotten a one. That's quite strange.

You don't think the LS1 injectors we just put in would be enough?
And would the 52mm be too much air?
And I'll wait to see how the poly mounts feel in your car lol

I'm gonna look at the pistons when I pull the heads off and see how they look. Worst case, I'll have a 383 when I'm done lol. I've thought about the oil consumption and kept an eye on the dipstick...it stops right above the last hole on the stick, which is right where it sits if i put in the 4.5 quarts the book says. So, I think it was just getting rid of the extra oil. The question is, how?

As for the 12-bolt...well, that'll be a little further down the line

That's weird you haven't gotten any texts I'll see whats up and text other people to see if it gets through.

LS1 injectors? You mean LS6? And I personally believe that won't be enough. You can calculate duty cycles here http://www.rceng.com/technical.htm
MadZ28 even said from what he's tuned, they flow minimally over stock LT1s at 43.5. That could also be why your initial tune was too lean.

I believe the 52mm throttle body would be worth it if you're doing H/C.
I've always thought about doing top end...believe me I have...but what always pulls me away from it are my weak hypereutectic pistons, 110k miles, and 2 bolt mains. Well, that and all the work involved, lol.

You better do the bearings. It's common to spin them after a head/cam swap.

[Kevin - Blown 95 TA]

Some piston damage isn't obvious from the top. If the rings are stuck or the rings or lands are broke, you probably can't see that unless there's a tore up area in the bore.

[TraceZ]

You'll need new fuel rails too. The 93 was different. The LT4 manifold will have the groove for the crossover pipe in front.

what about a big shot of nitrous

Got that already Trace, but thanks

So, basically, you guys think I should just pull the motor and rebuild it if I'm going that far already?

Eh. I'm not a big fan of nitrous myself. I need another liquid I need to keep topped off on the car like I need another hole in my head lol

u gotta let the hot air vent somehow

So, what you're saying is, you want to be visited by Joey Bag-O-Donuts and Muscles Marinera? lol j/k

[Z Ya Later]

Well, looks like my plans are going to have to change. The LT4 kit is no longer available, but I can still get the heads. The intake, however, I'm having trouble finding (not that I can buy it right now anyways lol). So, this brings me to another question...can the LT1 intake manifold be modified for the LT4 heads? Is this a wise move? What needs to be done? What approx. cost would I be looking at?

Also, would the hot cam still be a good choice for good driveability and decent mileage or would there be a better choice? Would a better choice require work to the LT4 heads? Thanks guys.
