Is it worth modifying a SOHC VTEC or is it just a waste of time and money?

Unboosted D, yes. Boosted D Series isn't that slow to be honest

this is an age old question guys...

the answer to your question is not a simple one. there are numerous factors that come into it including finances, how long until you can afford another car, how long until you can afford a B series if you wanted one, how far are you willing to go with the D series motor etc etc etc....

it is an individual value judgement. As you can see, there are people who think the B series is the answer to all of lifes questions, and others who think the D is a worthwhile investment.

you are not going to get an answer...

If you ask me... i'd do some simple breathing mods, maybe advance the timing a little bit, and then focus on doing easy small suspension mods to improve the driving feel...

Like I said, either he's a shit driver or his B16A is running sick.

But with identical health, stock B16A will screw a I/H/E D16Y1.

I drive an EF8 CRX SiR, compression was near new (215/210/215/220), has CAI, headers and axel-back. Made 99.4kw ATW.
My EH9 Civic VTi has CAI and headers and I reckon it's much slower.

Also, I already stated that you can boost a D which would make it fast.

a boosted B series isnt that slow. if you want to be like that.

stop giving him hope with it.

do handling mods so your car will be a rapist when it finally gets its b series.

**MikeyG** · 26-05-2010 10:34 PM

yes unless your going to boost your d series theres not much you can do... and honestly its pointless... spend your money on handling and sussy mods.. maybe even exterior and interior mods save and swap a b series

If you wanna stay N/A then either tune your car or if your really keen go b18 or turbo

As Firepower mentioned 'everyone has a different perception' on this topic. I was ready on how to modify D series for ages an was into it for some time, but then started reading on b20 and made my mind up to go b, so I have started a b20 build; but again the decision comes to the person and money.

The Issue why mod a D when you can go B OR why mod a B when you can go K will always exist in the Honda Community.

So at the end of the day it is your decision.

Personally my D has a CAI, DC2R suspension and by next week will have DC2R exhaust and that will be it.

Why would i lay out 3 and a half g's for just one car space, f that

lol, i agree with sajadeg,

b16a eg is a nugget. go b18c7 if ur going to bother with a conversion, b16 is not worth the money

b16 is over rated lol.

i still cant get my head around the guys who think stock b16 with win by MORE then 1 car length vs a i.h.e d16... seriously? 1 car length is a lot...too many ****s on here think they know it all

Definately worth modifying and not flogging a dead horse like a D15 carby, but for bang for the buck for your mods wont be as good as a b16a conversion, which in turn wont be as good for B18C. Would love to have an eg vti d16 project one day myself, even though I already have 2 B16a cars and a B18c7 car.

I thought they were a bit of a joke with just a hint of vtec from my prev experience with stock eg vti in Aust. I had a chance to try a fren's eg4 d15 vtec in HK and was seriously impressed. It was modded of course, still 1500cc cos they only had 1500cc to keep rego fee down and hence B16a and above are always above most ppl's budget over there to keep on the road for rego and insurance etc so ppl resort to moddy D15's over there. This engine had an aftermarket taiwanese cams ie toser, mfactory similar with power fc, taiwanese 4-1 headers, cam gear, thinner head gasket, mildly ported head, IM and bigger TB and had the stock airbox to keep it street legal. Not only it sounded really good and onsong but 0-100km/h was within 0.5s of an ek4 with b16b drivetrain, logged under same conditions with my Performance box gps datalogger. Gearbox was stock, but it had a taiwanese 4.7FD and flywheel was a lightweight one too. With your bigger d16 bottom end it would go even better.

You wont need to worry about the usual conversion bits with this route and dont need another gearbox but cost is still far from cheap with the parts you need to source from say mfactory and the labour involved, and the tuning needed. It will be more special than the usual stock b16a conversion though and the front end will be slightly lighter too.

The B16A is a fantastic, revolutionary motor with a soul behind it's history. It lacks torque because it's a 1.6, but the B16A is supposed to be rev'd hard and when you know how to drive it it goes very well if it's healthy and unrestricted.

When you talk about 'one car length' how far are we talking about racing? 200m?

Like I said I have a B16A CRX and a D16Y1 Civic and I'd put my B16A up against any D16Y with I/H/E.

The main point we're trying to get across is that the D16Y is an economy VTEC motor, not a performance one. It's stock power and potential are both infinitely more impressive than a D16Y. This is why we advise people against heavily modifying their D - once you spend 2-3g on a D16 you may as well have considered a B16 simply because yes they might be just as fast, but at least with the B16 you still have room to keep modifying.

Rep for you hisoka.
