I've been getting weird ideas about an OEM engine build and just wanna know if its possible?

b18c bock w/ LS crank and rods
p30 pistons
b16b head

yeah thats what I got so far but I asked my friends that they say i might have some cleanance problems?
 
if you use 100% OEM parts (including cams, and cam gears) you wont have any clearance problems. but depending on what cams you choose you will have to check the clearances and make sure you are ok.

ive also seen people have some issues with the oil squirters when using the ls crank in a gsr block. some people say you can slightly bend them out of the way, some say it will hit. you can avoid all this by plugging the squirters.
 
basically same setup im doing but with a gsr head, those spec 4 cams im was talking about it my other post should work... right..
 
Why use a gsr block? Unless you are getting a sweet deal on the block, I'd just get a b18b block and call it good.
 
because my car is a gsr and im just gonna keep usin the block lol, save some money, plus.. i can still tell ppl that its stock and make it a sleeper cause they wont know its ls/vtec internals and high cr

that is gay. And there is no worthwhile reason to put an LS crank in a gsr unless you messed up the gsr internals you have. For the tiny bit of displacement you get with the LS setup, you lose the GSR's factory ability to rev easily, and have to spent extra unecessary amounts of money to build the LS bottom end to be reliable at the high revs.

As to my post, it wasn't directed at you as you did not start the thread.

It's nice to have the extra displacement with the factory girdle setup in place. The additional 1.8mm of stroke does start to add up faster when your bore is considerably wider than stock too- but I don't think that's the case with his build.

:)
 
but doesnt that little extra displacement add about 15ftlbs?
is getting ls rods and ls crank in place of my gsr setup worth it, will i really see any additional gains?
i mean hell if im not going to see much of a gain there is no point in looking for extra shit to put ls internals in it, i was told that little bit if displacement makes a noticeable gain
 
235-250 whp and i will be completely satisfied
thats my power goal. i dont have to me pushing any more than 223 to make a car run a 12 sec 1/4 mile and thats even with a stock b18c5 block
i know the numbers im looking for are in the head, the b18c1 block im using has almost 200k miles on it is why im rebuilding it in the first place and when i rebuild it if i can do little things to make it run better and faster i want to do it, if the ls is going to give me less top end then i dont really need it because im going to be taking it to around 9k
that is why im asking if its worth if because if not im just going to take my gsr shit and get it rebalanced and all the shit honed so its like new
 
if thats your power goal then you need to start thinking about sleeving the block.

and the ls crank (with 81 bore) wont give you 15 lbft more then the gsr.

and how do you know what rpm your peak rpm will be before you even build the block? its not like the power just keeps going up if you rev it more. fuck if you could do that, id bullet proof my block and rev it to 20k. build your motor, find where peak power is, THEN decide what you rev to. seriously it sounds like you just want to build an engine so you can brag to everyone about it, and tell everyone you rev to 9k. i mean, hypothetically speaking, say you build your engine, and it makes 250whp, but at 8k? you gonna tear it down and start over cause its not at 9k? pick a power goal, not an rpm goal. ive told you more then a few times that from my knowledge and experience that your power will mostlikely top around 8-8.5k, are you still gonna rev it out to 9k just because? or to "hear how cool it sounds"?
 
i only say 9k because with those big cams they may go that high. hell id be happy with 7k but if its going to keep making pwer i want to keep going
 
and im telling you that with your setup your power will motlikely peak at 8.5ish. dont get so caught up on the number, just stop reving when it stops making power. no need to go more then a couple hundred rpms past that.
 
depending on your setup, compression, and head work/cams you can decide how high to spin a motor. the higher the compression, the more power you can extract from the head. all cams are different. for example: s2s1's = good power from mid range up. s2s3's = for high revving. you need to build the head to handle the higher lift and longer duration plus the higher rpm. springs/valves/retainers. you cannot spin motors higher than the stock redline on STOCK valvetrain. you will eventually damage the internals. especially float valves. so figure out what you wanna do. ls/vtec's dont spin high due to the long rod stroke. my old ls/vtec had stock bore ctr pistons, shotpeened ls rods, manley stainless steel valvetrain, itr cams and bolt-ons. chipped p28. vtec @ 6800. I spun that motor to 9k. that = no no. motor lasted for 3 months if that then i spun a bearing. BUT i made power all the way up to 9k. the weak point of that motor was the rod bearings. they wear out quickly due to the long stroke. long stroke + high rpm = no no. good luck with your build.
 
The original thread starter has pretty much left because of all the off topic posts. The thread was about building a performance motor with OEM parts and you have all pretty much mucked it up. Go start your own thread if you want to ask questions pertinent to your build.

usdm integ, sorry, but I'm closing the thread. Start a new one if you need to, hopefully there won't be so much threadjacking in the future.

Closed for excessive threadjacking...
