can u vtec a nonvtec engine??

[Killa From Manila]

yes, but depending on what engine it is

[typsy]

I think you just answered your own question.

Non-Vtec = No Vtec

[riruiz_88]

can u vtec a nonvtec engine??

yes it is possible, most popular being the B20 (CRV) bottom end and a B16 (crx/civic) top end. though with the money you may aswell do it properly, do an engine conversion. gives you less hassles and will be better in the long dude :thumbsup:

[omgzilla]

The only viable way of doing this would be, as riruiz_88 said; putting a vtec equipped head onto the current bottom end - providing they are a correct fit.

It would probably be cheaper to do it this way - but if it's not done correctly it could end up costing alot more than a complete VTEC'd motor swap.

I wouldn't think that anyone in their right mind would attempt to fit VTEC components to an originally non-VTEC motor. It wouldn't be cheap, alot of customization would be required and i'd presume it would be a pain to tune and/or get running well... regardless of making a, most probably, not worthwhile performance increase.


What engine does the car currently have?

[aaronng]

Only if the head matches the block.

[dsp26]

yep as stated by everyone above... on B, K, D series it's been done... however i've never heard of an H22 head being put on the H23 if it's for your prelude

[dmaccaster]

see i was thinking of doing this to a b20a, instead of a h22 swap

Lets put it this way, it will not work out cheaper or easier than a h22 if that is what you are thinking!!

[riruiz_88]

it is different i can tell u that. but if you go the B20 way, you will be running weaker internals/seals and the list goes on. dont get me wrong, its do-able but its up to you what u want. the H is already engineered to run at higher RPM, so obviously it will have better internals. just something to think about man

[B16bcivic]

guys guys guys,

i don't know what im saying but, h22 blocks can still fit to b-series parts. h22 can be put onto h23 bro. its been done in usa. anything is possible. i think. lol. jk it has been done, atm im running b20 quads with b16b head. damns its so fast.

[B16bcivic]

bro. running a b20 depending on whats been done to it and whats been put into it, as far as i know my internals in my b20 are all worked, depending on your budget. As for h22 they r good but is still slower then b20s bro. i can garanteed you that even if its the type S h22a.

[beeza]

It's called a mini-me conversion.They do them in the states all the time cause it's heaps cheaper.Unless you can source the parts cheap it will cost a bit and won't be worth it.

might take the opportunity to hijack the thread :P

is it possible for a b18b engine?

Yes, but you might as well make a B20, as a B18B (in the sense you are speaking, B18A block, B16B head) would most likely be only equivalent to a B18C-R

yes, one of my friends has 2 integra's, one was vtec, the other was not.
he took the non v-tec bottom end and put the vtec head on it. From his research he found that the non-vtec bottom end was stronger then the vtec end, being vtec engine they must of wanted lighter components for faster engine response. the reason he did it was because his v-tec one had done a lot more km's then the non tec one.
didn't cost him much at all. mostly just time.
not sure if anyone out there can confirm the difference in the internals.
