Need your help LS/VTEC vets only.
I had a topend built ls/vtec, but it put 2 holes in the #2 piston and dropped a valve...
Im looking to build another and Im llooking to make about 250-260 at the wheels NA
Should I get a LS block(which I happen to have a spare)
or a B20
Ill be sending this block to Ge for sleeving and cleaning
Im looking for the size to be 2.0
before I had a b16a head p&p with crower STg 3 cams and upgraded valvetrain
This motor will ONLY see race gas, and hondata/zdyne
so if anyone can lay out their ideas in parts/specs/and brands that would be a great help. THanx

Oh yeh, parts must work well together, dont have to be rock solid, but at least last a few months, Price isnt THAT big of an issue as I will be building over about 8-10 months, im also looking to see revs up as far as 10.5-11k (Damn I miss my old gsr/b16a)

Re: Need your help LS/VTEC vets only. (Soulracer)
you sound a bit shady, someone that really has ls-vtec should know that the B18b and the B20 are pretty much the same except for the 84mm bore(sleeves)... and if your gonna get your block sleeved you can just bore it to 84mm and there you go! ...2.0 litters!!!

Re: Need your help LS/VTEC vets only. (10K2HVN)
and what were you revving to with your previous motor?? and why did it fail?? and 10.5 to 11 on a ls/vtec! holy **** is that even possible??? i thought it isnt safe to tach a ls block past 8k or so?!?

Sleeve the LS block to 84mm or get a CRV and sleeve it to 84mm either way you're gonna want some sleeve strength.. Drop a B17 crank in with some high compression pistons and some rods... For the head send it out to Portflow then find some cams that will make power up there.... This is just a waste of time... You may be able to make a motor rev up there but there is now way that you are goin to be able to get power up to 11k.... Go check out Erick's racings dyno plot on Hondata.com they begin to loose power after 9900.. http://www.hondata.com/dynoericksracingrc.html I think you would be just better off building a GSR if you wanna rev that high.. My friend had JUN3's in his CRVTEC EK it had high compression pistons, stock rods, portflow GSR head, S2 manifold, RC 310's... That motor was stronger only because of those cams than my other friends CRVTEC EK now.... They are the exact same motors only the new one has CTR cams and the old one had JUN3's... That car was way stronger than my friends with the CTR cams and my friend with the CTR cams ran a 12.62@107... Those JUN 3's can make power pretty high and we still felt a drop off with them at 8800rpm.. Erick's Racing runs Toda D's.. I would just build a motor that will safely go to 9000.. That's all that it takes.. My friend with the "CTR cam CRVTEC" shifts at like 8300 with an ITR ECU and it's not bad for being in an EK!! Do what you want but just like boostin18 said, why did your old engine fail...

Re: Need your help LS/VTEC vets only. (Soulracer)
Well when I first got ahold of this car, it had a fully built gsr with a b16a head
I saw the car run a 12.4 from the previous owner, then when I bought it I ran a 12.5 It failed because of the rod bolts over tightend with my knowledge, then there was a oil leak form the oil pan gasket, the motor was buil tto safely rev to 9200, but the previous owner said hed reved it to 10k form time to time. I never reved it past 8500 but I spun a bearing and scratched the crank, and the clyinderwalls were scrathced somehow, so i ditched it and got a ls block and slapped it on with out knowing much, i didnt really rev it high like 6700 or so, valved dropped and there it went.

Re: Need your help LS/VTEC vets only. (Soulracer)
after looking at that plot, thats exactly what im looking for to the "T" any way I can get ahold of the people responsible for that beast? I love that flat torque curve(or lack there of) How often is the motor in need of a rebuild?

Thinking about getting that block girdle z10 so i can rev higher a little more safely but i got to talk to my friend about it to see if i need it...
my friend was tellin me about his friend who has cr-vtec in his hatchback and runs an official 12.4 1/4 mile with a fully built top end and stock bottom end...

Honestly, with all this talk about high revs and CRVtec or LSVT, if you're gonna send the block to GE and bore it anyway, you're wasting your time with an LSVT setup. You don't neet and LSVT 'vet' to tell you this. And dropping in a B17 crank ? Why bother doing an LSVT ? You'll gain much less than the already negligible 33cc.....
Just go with a GSR block, sleeved and bored. You'll get sooo many more pluses with it... #1) You'll get proper, stock oiling to the head #2) You'll have a stock block girdle set in place #3) You'll have piston/oil squirters w/o affecting block integrity #4) Your stock R/S ratio will be a LITTLE friendlier.
Don't get me wrong...LSVT is a nice little setup, but with the time and money you are obviously willing to put into this project... save some headaches and some $$ and just source a GSR block now.... power from a CRV or LS block will be a myth once you start talking sleeves... and that's the skinny.

Re: Need your help LS/VTEC vets only. (Soulracer)
I love this stuff 
It sounds like you like to rev. If thats the case I would not recommend ls/vtec.
If I were you, I would get a b16a engine and go ***** out on that (1.8L stroker)
For as high as your gonna rev, that would be prime w/ high comp.(13.5:1) and stage 3 (any kind) cams. On the other hand, a gsr would rip too. but b18c's are kinda pricey.

Exactly, CRVTEC's and LSVTEC's are cool but why not just sleeve up a GSR.... 85mm bore = 1.98L motor, 13.0:1 compression daily driven in an EG.. wahhhoo

Re: Need your help LS/VTEC vets only. (JDMspecEG6)
well i never met the guy, but its in a hatch, so i think thats how he got 12.4...
...and as for the other guy; honestly, if i could do it again, i would fully build a B18C1. <sleeve, bore, port, polish - the whole shabang! but, i took this route, but its still kinda fun (more funny then fun) NOT being able to hook-up 'til about half-way through second gear - lauching from 2000~2500 RPM.. and the mad torqe-steer when vtec kicks in - nothing better then looking like your about to run into the your racing...
oh yeah, my friend runs low 13's in his ITR with a fully built top end, stock bottom...
cheers!
EDIT: well its not *fully built* yet, still needs and intake manifold and larger thottle body.. he just got it dynoed, less then 2 months ago, 191 or 193 to the wheels! 190 something...

Re: Need your help LS/VTEC vets only. (X2BOARD)
yeah i guess your right. do a high compression b16a w/ fat cams and big intake manifold or individual throttle bodies
individual throttle bodies
