last year i blew my lsvtec and Im debating on whether rebuild it or drop a k in my crx

 

B20 VTEC

 

the ls vtec made 251 all motor on a dyno jet

 

Go K

 

I want to but I have all the parts for the ls vtec all I have is an extra k20 shortblock

 

i see, its all personal preference and how far your pockets will go then

 

If you have the $$, it's a no brainer. End of story. K.

 

I have the money to rebuild my lsvtec but I can sell my all motor setup and buy the rest of the parts I need for a k20 build but it will be a mild build not a fully build

 

What are the circumstances behind it blowing up? 250whp is a lot for any b-series.
I know people say k but 250 whp from a stock crank k20 is no walk in the park either.

What did you have in the lsvtec?

 

b18a1 86mm rs sleeved
custom wiseco 13.7cr
rpm rods
balanced blueprinted polished crank
b16 head p&p it flows 295 or 290 I think
bc specV cams bc valves springs and retainers
jg header 2.5 collector
hybrid AEM CAI
blox IM open and ported by blueprint
all the MSD ignition plugs blaster coil and box
tuned on crome
100 oct

 

oil starvation was the cause I want to switch the header a smaller cam and a new head for a new port blueprint say that they can make it flow over 300cfms

 

250 in a k is easy on a dynopack

 

250 isnt a whole lot for that build. Especially at 86mm.

Sell everything, buy k24 stock bottom end, use a k20 head with some decent cams , rbc and header.

thats what i would do

 

I want to make 270 so I can either rebuild the lsvtec with a better head cams and header or do a k24 and do a mild build 270 on a k is not easy to make and Im colser to hit that number on a b than k

 

i'd have to disagree.

270 can be done on a stock k24 bottom end pretty easily. You just need the right parts.

You can hit 270 with that B bottom end as well, but you are correct the head/cams will need to change.

You can hit up Import Sports , they have a sick all motor b series build that makes more power than most b series builds

 

no way it can be done on a stock bottom end with 10.5cr tsx pistons

 

I will like to see a stock bottom end k24a2 or k24a1 whit a k20 head and some cams the
most I seen is 240 but mad torque

 

well I spoke with jeff from blueprint he said that they can work with my head and make it flow 320cfms I got the header now should I stay with specV cams or switch it ?
I think with a better port I can make the 270 on the b series
should I run 550cc or stay with the 440cc?

 

That will be the best B head ever. I would go with that. What class is this race car in?

You can definitely make 270 with that type of build. Get a VictorX IM and a custom header and you'll be right there.

 

I got a hytech replica I want to see if it will work

if ur talking about the 270 all motor in the club rsx forums its not the same thats a k24/k20 build for my rsx this is the b series 270 goal
