Now obviously people out there will think that there are some links missing to this bible and that is obviously true. That is where you guys come in. If you think that there is a useful link that should be in here the please post it and I will add to it. The bigger this thing is the better.

Oh and to some of the sites you have to be a registered user (and some you even have to have a certain amount of posts like night-stalkers) before you can view the material. I wish that this wasn't the case because information should be readily available but I guess I see where they are coming from.

Well thanks for looking

EDIT: added a few more links plus your's nightkid (thanks)

I have one problem with the "How To Build A KA24DE'' thread. Great pics, pretty good writeup. However, plastigage is probably the worst way to check clearances between the journals and the housing bore. If you are planning on building an engine for high performance, you need an accurate measurement. Go out and buy a dial bore gauge and an outside micrometer. This is the MOST accurate way to measure. The only time I would ever use plastigage is if the engine was still in the car and I was putting a new crankshaft in.

Also, If the main housing bore is out of alignment and has to be honed or bored back to specs, you don't have to get oversize OD bearings. While it's at the machine shop, have them take a little of the flat part of caps and where they mate on the block. Then your bore is smaller than it was and you can align hone it back to factory specs and use normal bearings. This is just an alternative if oversize OD bearings are more expensive, or harder to find. I haven't done research into that part yet. I'm just starting.

Overall, good write up though.

Cleaned up all the whoring, like I've said everywhere else, there should be no more whoring here after this post.

If you have something you recommend adding to this, add a link and a short description what the link is of, and I will make sure it is added to this list.

Ok so i have a question. I wandered what the actual weight of the SR20 is. or a round about estimation. I hear alot about the RB26 swaps but how the weight diff isnt worth the horsepower gain. Is that true? or just a way to make themselves feel better about not being able to afford the RB?

weight is a silly issue when it comes to motor swaps. unless its drastic. an RB26 is not drastic.but it sounds like a pipe dream to me.

no i just purchased a 96 240sx and had a few grand left over. I was told to dump it into the SR...ut im tired of seeing that swap done. So ive been looking around and i can get a R33 front clip for about 3k and I KNOW i cant put it in myself much work. so another 2k im shure to have the conversion applied. my bank allows me to do it but i didn't know if it would be worth it in the long run. just looking for some advice. I personaly live in bucktown lol so a 240 is rare anyways so i almost dont care. but as i said you open a superstreet anymore and boom 15 silvias with sr20's so yeah im looking to spice er up. also is it true that you have to re-route crap to make it work with left side drive?
