New guy here looking to build an L33
Im looking to build a Nissan 240 with an L33. The last 240sx had an SR20 in it, although the power wasn't bad could always be more. In my opinion wasn't the most reliable either. Therefore this time I'm looking to build something with more power, and also quicker on tap. The two options are either an LS1 or L33. Im looking to build something in the 500rwhp range, preferably closer to 550, but reliable.
I know most will say to read the treads, and well I have. For the last two weeks plus I've search a large amount on the LS family to make sure it was the best path, everything from LS1, L33, LQ4, LQ9, LM7, LM4, L59, LS2, LS3, LS6. Everytime I search for information it brings me to this site, so figured hell I just post here get roasted and get some info.
Everything I read tends to steer towards LS1 but they're becoming more pricey and from Im reading close to, or at, the 500rwhp mark some serious work needs to start being done in order to handle (at least NA it seems). With the only real plus being that it would fit under the hood without issue.
As for the L33 there seems to be a decent number of them available ranging from $650 (w/200+miles) or $1,400 (w/100+miles), so more wallet friendly. Not to mention when I search what kind of power can be made every search ends me here with people talking about turbo'd L33 with crazy high HP numbers.
So now where the help is needed... First which base option is the most suitable LS1 or L33? Honestly Im leaning towards the L33 where there are more motors around, so it seems, and can handle being boosted.
If I do go L33 what would I need for mods like cams, heads, headers (out of a truck perhaps?), springs etc. I see a lot of threads saying to keep the heads, and say the heads are the same as the LS6. Are the heads on all of the L33s the same, or is there certain years with those heads I should look for?
Any recommendations for turbos, I see a lot of people opt for the T76. Im looking to drift the car so I need something that can put the power down Im looking for without being maxed out. I also don't need too big of a turbo capable of 800+ when it just wouldn't work for what I want. Also something that spoils up early and can maintain the power band would be nice.
What would be good intake, injector, and fuel pump options. I know Holly sniper intake manifold are nice, but also $500+. Like anything else people push the products you don't always need that cost the most. So instead of wasting time and money when I don't have to figured I ask you guys who can build these things in your sleep. So valve springs/pushrods/rockers options would be nice as well.
I think the smaller frame T76 will give you a nice powerband with the necessary spool time but others may have better recommendations. An LS6 intake with some 120 lbs injectors should do the trick assuming you are going with E85 unless I missed it.

Stock Long block. LS1 intake manifold to fit under your hood (don't spend a dime extra on an aftermarket intake), SMALL cam like an Isky Triple 12, and an efficient turbo like the a Borg S369SXE would spool very quickly, make 500whp, yet be capable of another 200 should you feel the urge. That's all. No aftermarket heads or intake, and you could still manage 700whp.
Fuel pump will depend on internal/external. Walbro 450 for internal, AEM 400 for external.
Fuel injectors should be in the 60-80 lb range for headroom. Stock decapped L33 injectors are ~75 lbs. Otherwise, the go-to for 60-80 lb injectors are Siemens Deka injectors. Don't get them from Ebay, knockoffs are getting to be way too common.
But yes, the L33 basically has LS6 heads.
Change the springs. Spring choice will depend on cam choice. Blue LS6 springs are $60-70 new. If you plan on sticking with a stock or very small cam, they will work.

L33 motor
stock heads (basically LS6 heads)
cams- Isky Triple 12, what else is equivalent? If I'm looking to drift what cams can provide enough for 500-550whp and high revs?
Blue LS6 springs? LS7 springs? something to handle the boost, yet also the revs.
LS1 intake manifold
Walbro 450 fuel pump
One thing I have been running into is the accessories. I see kits that have everything for $1,300, but that seems a bit high. What would you recommend for accessories and from what vehicle? Have heard LS2 water pumps can handle keeping temps down. Like everyone looking to get to the goal as cost effective as possible because caging the car will be somewhat pricey haha.

I would probably go for Howard's springs. Part # 98113. $120 shipped from Summit.
I dunno what accessories fit a 240. I use stock truck accessories in every swap I've done. You can probably get a used set of F-body accessories for $300-350, those might fit better.
Also, not an LS question, but where can I find a CD009 trans. I see them post on ebay but can't tell if they're really CD009s or not, and not sure where else one can be found.
Appreciate all the help.
If the base circle on the cam changes, you may need longer pushrods.
