probably if you haven't done it before, I can knock one out in about 30 minutes but I have done it a few times and use power tools where possible. It's been pretty much the same process since 00 or before, the older ones with a fan clutch just had a shroud to take off, you could take off the top part of the shroud and leave the bottom part in. the hardest parts are getting the lower hose off and on and those trans lines clips
Sweet, well, I think I'll head to harbor freight and pick up those pick tools tonight

You got one of those big picks for breaking the hose seals? Don't forget about the restricter for the overflow tank hose.

I bought two sets from harbor freight, a large set and small orange set. Not sure about a restrictor, I'll see what I can find. I've never done this so YouTube it is.
The oem radiator he ordered won't have that issue
[emoji1745] I just ordered from the link you sent

that's a factory radiator don't worry about any restrictor that's something that the aftermarket units screw up sometimes

So what's an estimated time for replacing the radiator? 2-3hrs? I'm gonna attempt this tomorrow and Wednesday. Gonna watch a bunch of YouTube videos tonight.

I know how my life works and how Murphy's law is always apart of it, so I want to give myself ample time to get it done

You'll be fine Phil. I went to help my daughter change her radiator and she sent me back inside and changed it out herself. Very proud moment for a teenage girl.

I read up on their site, but couldn't find an answer: What's that tab that you cut off for? Fuel pressure regulator?

Throttle body cable bracket for a DBC throttle body. I called them on the off chance they offer a lid without one for us DBW guys that I could buy separately, but they said no plans in making one :(

Stay tuned though, it's going to look badass.

I've read that the fast lsx is pretty good but takes a lot of moving other stuff around to make it all work.
how much was it? did it come with those rails and injectors?

I'm in the middle of a nitrous build right now so things are already getting moved. It's really just sensors anyway. It was $998.95 to my door, comes with rails but not injectors.

Nice. What kind of HP does that add?

More of a supporting piece than a power adder. The stock L92 manifold hangs with most aftermarket options on n/a setups. However I opted to go with it over stock for the longer runners, putting on a 102mm tb, and it is molded from the factory with locations for direct port nozzles.

The plenum volume and runners were the main factor, I'm running TSP's 229/244 .629/.615 112 LSA LS3 cam, Cirdle D 3400, and front/rear 4.11s. So it's a perfect fit to match the low end grunt that everything is set up for.
