Just a couple questions I'm curious about to help me decide what parts I need so I can build this right.

Engine will be LSVTEC, B18B block, PR4 rods, PR3 pistons, PR3 head. All else is under construction. Engine will be N/A with goals of 200chp. I'm planning to port, polish, mill, hone, balance...I think that's all the machine work taking place.

Let me make it clear that I am not interested in buying parts from vendors or private sellers at this point in time. I am simply trying to do some research to figure out what I need.

Please keep in mind when advising companies to look into for particular parts that although quality of the product, dependability of the product, and longevity ARE important to me...but I AM also a student, so I AM on a budget. Thank you in advance for any help you can provide, and please check back now and then to help me out. Thank you SO much for any help...

1. How can I decide what size fuel injectors to get, and what companies are good? I don't know how to look up much on fuel injectors, so please give me any guidance in regaurds to them that you can, and feel free to advise manufacturers.

2. How can I figure out what size throttle body to go with?

3. What camshafts should I be looking into? I want better than stock, obviously considering my goals, and I've heard alot of talk about going cheaply with an ITR camshaft, or spending boo-koo bucks to go with buddy club stage (fill in the blank) and Skunk2 stage 1 or 2's. Please, again, feel free to advise companies to look into, or advise stock cams from other heads. I do plan to have the head ported.

4. What valves are good? I've heard good news with BuddyClub's and Skunk2's. Is one better than the other? I plan to have a 3-angle valve job done on whatever goes in with compression ratio up to 12.5:1, but I'll probably end around 12:1.

5. What valve springs should I check into? Yet again, BuddyClub and Skunk2's have been at the top of the list, but I have heard that with the Skunk2's, sometimes you'll get a bad one that will break.

6. What valve spring retainers should I look in to? Skunk2 and BuddyClub both offer a titanium retainer, but I've heard bad things about titanium retainers in that they tend to get...mis-shaped after time. Please shine light on the topic, and share advice.

7. Will my LS OBD1 distributor work on the Si head? Or do I need to find another one? If so, are there good aftermarket ones to look at? Or just shoot for good 'ole Honda OEM?

8. Intake Manifolds. Who makes a good one? Should I look for anything particular? Or will good-ole Honda Si do the trick?

I think that covers just about everything I have questions on right now.

Feel free to ask my questions to help me out better, and thanks again in advance for any help.

 

Bump for the late-night crew.

Ah, yes...you missed the questions about "Why" so that I can further my education on how certain things affect what. Thank you for the reminder on using the search link...I've used it several times and even through all those results...it didn't answer all my questions.

Thanks, though...

 

And bump for the evening.

 

as far as valves go id definitly say that youd probably be better off sticking with stock ones assuming you have them. For what your shooring for they should be fine, that will save you a couple hunded right there, high comp valves/racing valves are overrated unless your trying to go nuts with your motor.

as far as aftermarket manifold iv always been a fan of http://www.JGenginedynamics.com they have realy nice sheet metal intake manifolds, also they have good affordable cam gers too.

Im not much for Skunk 2 except the springs and retainers, they have always worked for me

oh yeah... your non Vtec LS Distributor will not work, get and B series vtec OEM one

 

Thanks for the help on the dizzy.

Springs and retainers...I'd like to get more feedback on, but thank you for your input.

I'll check their intake manifolds later, as well as their cam gears.

I don't believe the head I purchased comes with the valves. Bought them from an HT'r, and I think he said they weren't in the head. I can easily purchase stock ones again though, I just wasn't sure if they'd hold up to 12.5:1. Not looking to go nuts with the motor...just a car that can get the groceries in a jiff.

Thank you for your HELPFUL response.

Looking for more feedback from other HT'ers! Thanks again in advance!

 

Morning bump

 

1.I have a fully built ls/vtec as well you want 310cc injectors or even prelude 290's should do the trick.

2. Dont go with anything bigger than a 66mm TB.

3. As far as cam look in skunk 2 pro 1 camshafts they are nice.

4.Valves you cant go wrong with skunk2, buddy club.

5.skunk2,buddy club, or omni.

6.skunk2,buddy club, or omni.

7. The distributor no sure.

8.The whitfield racing fully cnc-ported ITR manifold---->also get a good header smsp,hytech etc....

9. With that setup you should have a potent ls/vtec just make sure you get it tuned on something like hondata or something.

 

What's your dyno read at and what transmission?

 

my motor build is still in the works I have a full LS tranny but i also have a GSR tranny with a big hole in the case (motor mount got ripped out in an accident. Im thinking about putting the GSR gears in the LS case but iv gotten many mixed opionions about this. I wish to BUMP just because i too am curious about what tranny should be on an LS Vtec. My weak spot is without a doubt transmitions.

 

the LS dizzy WILL WORK!! you just have to cut one of the legs off the dizzy so it'll fit. run it on 2 bolts. many people have done this.

 

From what I understand on transmissions...
You've got the options of an Si, LS, or GSR tranny...this is all USDM stuff...and excludes anything JDM.

The Si transmission is excellent for acceleration, getting around town, and say 0-75mph, so it's not that great for highway travel and conserving gas on road trips. It can be found fairly cheap.

The LS transmission is a cheap transmission to get because everyone's "upgrading" for better accelration. The LS transmission is not a tranny for low torque due to it having such...I always mix these up...long gears. So it's great for highway driving because you'll get awesome gas mileage, but you'll lose some get up and go.

The GSR tranny is a mix between the two of them. It has outstanding acceleration and pretty good highway gas-conservation. The gears are...so to speak...a good cross for a daily driver because you'll have your acceleration and highway driving pleasures. Due to it's value...the price is usally more up there...

That's ABOUT the best I can do to help you on that topic...

 

Cut a leg off? This doesn't sound too healthy for the dizzy. Many people do it you say....but...successfully? I suppose I'll await the head to get here and see how the LS dizzy hooks up. Then I'll probably make my decision. I just hate to throw out the LS dizzy since I already have it in my hands, and I know they're not worth much to sell, and Autozone sells their Si dizzy's from 200-300$ for a new one...I'd like to conserve cash. Maybe I'll use the LS dizzy until I can afford to get the Si. I wouldn't think the Si would put out more spark than the LS...would it?

 

kill two birds with one stone and go with the itr manifold worked by whitfield inc and get the rage header from them as well

 

Got a link I can check in to?

which head studs did you used in your ls/vtec

 

NA, who?

 

you and everybody.

 

Mine isn't built yet. I'm debating over OEM or ARP. I hear OEM is just fine (so long as they're not stripped or cracked) up until you start hitting high compression rates, then I've heard ONLY good things about ARP. I would trust anything else, and one of those two will be the only thing I trust in my build.

ARP are what are holding my rods to the crank...

 

i know this isnt my post however since we had been talking about transmitons, my buddy has a wrecked GSR and the tranny mount was ripped out of the case, i am planning on buying the gears for him and putting them into the LS case. iv been told this will work. If im being retarded let me know

 

I can't say much for this as I'm not sure, so don't take my word on it...but I think that any B-series internals can go into any b-series case as long as the shafts are the same...

Anyone PLEASE feel free to shine light on this more than I can. My statement is only a guess...

 

bump

 

some general comments, not sure if you already know...

using the PR4 rods, you will need to modify to fit a GSR or ITR crankshaft rod journal.
The rod bolts should be upgraded to at least ARPs, meaning you will also need to linebore the rod bigend bore.
you need to leave enough room between head and block to accomodate some massive stretch at high rpms ... hoping the rods hold up, you're really risking...
The mods you are thinking will produce high RPMs power and you're cheapign out on the rods, either keep mods to give good midrange torque and not high RPM HP given the rods you plan on using or upgrade rods, like ITR rods with ITR counterbalanced crank.
