Just wondering what the thoughts are on this
Im planning on purchasing a used kit with 5000 or so Miles on her, Full kit m45
Here is my question
I have a 2000 Z Auto about 160 K on it
Not daily driven, weekend car/car shows
I am going to be redoing my top end
HO Cams, Lifters, Towers, Valve Springs
Thinking a Cometic Head Gasket
Changing the water pump, timing chain, tensioner while in there for good measure.
Should my bottom end be good to go with the blower without having to touch it?
I run Royal Purple for the last couple years with no oil burning or excessive blow by problems. Changed every 5 k
Engine seems to be in great condition with no issues ***Knock on Wood***
Car is stored for winter and i have time to get things done properly but don't really have the extra 800-1000 bones to spend on the bottom end unless completely necessary cause i dont wanna pull the motor either.
What kind of HP/TQ do you think i can pull from this setup, my other mods are in my profile
Thanks for the help

personally after all of the head work, i would have a compression test done and check ur main and rod bearings... ecspecially being that the ld9 is famous for spun bearings.
hondas are like tampons.....every pu$$y needs one...
mildly built 99' ln2, eagle h-beam rods, wiseco forged alum. pistons, cusco oil catch, t3/t4 super 60 garret, tial 40 mm wastegate, hp tuners, prothane mount inserts, 2.5" exhaust.
don't worry about the bottom end, the blower is only making 5psi
There is no need any bottom end work in preperation for the supercharger. If you have a problem with the bottom end it would be from the rod bearing due to the milage and engine design not directly because of the supercharger.
If you are going to replace the timing chain I would also replace the cam and crank sprokets since they are worn to the old chain. If it makes you feel better do the timing chain but I would bet you are more likly to have a problem with your rod bearing than timing chain anyway. I would not hesitate to replace the water pump though. I would also consider replacing the alternator if you think it might go sometime. With the sc on it makes replacing the alternator tough to near impossible without removing the sc.
Forged pistons and rods are by no means a needed with just the sc kit. It won't make enough power for you to worry about breaking rods and as long as you have a wideband and keep an eye on it so you do not run lean your stock pistons will be fine. If you decide you want to use a smaller pulley you would be wise to have a water injection setup installed as well to keep high intake air temps down and detonation at bay.
If it were me I would not even consider installing cams and a head gasket with the engine in the car. It would be a nightmare and would in my opinoin be just as easy to pull the engine and do it then.

Ya the m45 was designed to run on a stock 2.4, and with your top end work your head might flow so good you only see 3 psi
IIRC the gm sc reflash for the charger will not work on an auto car, definatly something your going to need to address....
honestly, with 160,000 miles on that engine i suggest at least freshening up the bottom end. ie... new bearings and rings. although you could run it and risk it, just realize that your pushing more pressure on the stock parts that have so many miles on them and are worn.
wade-taking the head off while the engine is in the car really isnt as much of a nightmare as you would think, sure it sucks... but if you took the engine out you would be taking out a lot more bolts and that takes even more time.
Its 160 000km's since hes Canadian, so about 99500 miles.
I think a supercharger would be a better route for your Darren. Alot less headache than a DIY turbo kit.
Not to mention, Supercharger Whine > BOV

When it comes to turbocharger vs. supercharger, that is
THE ONLY benefit that would make me choose the super over a turbo.

There is a auto reflash for the charger.

i can get you the CAL # for tha auto reflash if needed.

I drove both a 2001 turbo 2.4 and a 2002 supercharged 2.4 both at 5psi and both 5spd manuals. They dynoed within 3whp of each other on the same day. The supercharged car was hands down funner to drive and also 4/10s of a second faster in the 1/4 mile on that same day. From a roll the supercharged car would run away everytime. The only way it was even close was when you punched them both from a roll at 4000rpm. There is something to be said for the low end power a supercharger produces.

This isn't really the place for our disagreements Wade, but if the turbo was only running 19.7 psia and not making full boost right away (i.e. < 2500), then it was nowhere near its efficiency range. Assuming IAT's are close, a properly matched turbocharger will make more power every time over a supercharger, regardless what positive pressure it runs. I know you love your Eaton, Wade, I get that, and more power to you (so to speak)...but you simply can't trick the laws of physics. I personally love the supercharger whine and have a strong disliking for the blow-off valve sound. So, that is
THE ONLY reason I would choose a belt driven roots/twin screw blower over a turbine driven centripetal charger...but to each their own, I guess.

^ what size turbo?
to the guy who made the post. IF you dont want to spend $, or replace a motor , then boosting a 100 thousand mile motor isnt for you, stick to the car shows on your weekends.(not saying adding boost to a 100k motor= instant death)
I have noticed a trend here, you add/talk about a power adder and right away the talk goes into forged this forged that, cometic head gasket, HO cams. 1% of the people who talk this way actually end up doing it.
I agree go with the gm s/c for a reliable boost option. I ran it for years (stock pulley, every bolt on , no tuning)and was happy with it.
The s/c can be had used at a good price. There is alot of info out there, just have to search around a little and you will learn alot.
..................
to the guy who posted about centrrfugal s/c's. they are nice, but not for these cars. With the RSM kit, you mine as well wrap 4k$ around your air filter and drive around. At least it would run better.

when i'm done with my cetrifugal, it'll be capable of 15-20 psi. should be a little better than mid 14's
THe only charger worth the hassel for decent power is a rotrex unit. AND they COST WAY WAY WAY to much right now. Amazing units though.
My Cav
I give up...
i'm buying a VW those people love trees, so they should love eachother too... "Andy"
^^^ agreed but i got my hands on a Vortec for pretty cheap
^^^ if you say so... i've already done too much thread jacking on this thread so i'm not getting into that. look for a build post soon, i'm getting close to having the parts i need for 'stage 1' of the build

Can anyone guess HP and TQ numbers for this build?
Would you advise against the porting and polishing of the head?
Can i run my HO TB on this SC? If not can i modify it to fit?
Running HO Cams is going to take away from the SC? Any other feelings on this?
Can anyone advise me about head building to work with the SC?
If need be im sure i can save enough to buy bottom end stuff at the same time cause ill have half the motor apart already.
What do you think? I don't have any problems with this motor at all except a small pil leak very minimal from a cam tower gasket.
Ways to make more power with SC? I was thinking i would send it to Steigmayer over the Winter of 08 for Porting and Exterior Polish

something I was wondering,
if you put a smaller pulley on the charger you get more boost, which is good, but does would the reflash from the dealer still work with it?
I don't really know much about the sc's and just made me think about that a little
cheers
