Frankenstein, stroked b16a or JDM ITR b18c?

**Paul1985** · 04-07-2005 02:40 PM

Hey guys, i keep tossing up which b-series path i wanna take on an EG Hatch.. just after some opinions and/info on the three, ive searched heaps but cant work out which would be the best for my money and which would pump out the most performace.. i like torque and it is for street only, so some reliablility would be good also.. The options im tossing up between are:

1. JDM b16a w/ b20 conversion
2. JDM b16a stroked out to a 1.8lt
3. b18c Type-R

What do u guys reckon would be the best per dollar of the three?

best dollar per hp = B20VTEC

best grin factor = B20VTEC

most logical thing to get most power = B20VTEC

easiest thing to stuff up if you have no idea = B20VTEC

get a jdm b18c type R engine, hardto find though and cost alot

what do u reckon if a professional did the B20VTEC swap, someone with experience and they strengthened it?

im starting to like this idea

i like the grin factor

i don't think "hard to find and cost alot" matches the "best per dollar" requirement

have you already had this discussion with me over PM? many people have, cant remember them all...

BTW - a 'professional' will rip you off, and strenghtening of the block can be as simple as fitting new ARP rod bolts...

i think the cheapest would be to find an EG6, and use option 1 or 2..

**tinkerbell** · 04-07-2005 03:07 PM

stroked b16a is expensive too...

**Paul1985** · 04-07-2005 03:10 PM

i havent had this discussion with u tinkerbell

thanks for the info though, so im guessing your experienced with this?
If so, which of the 3 options would u recommend if money wasnt a hassle?

**tinkerbell** · 04-07-2005 03:18 PM

money no option = Dart block and head

but of the 3 options, B20VTEC is what i would go everytime...

my old B20VTEC running stock internals and only Type R bolt-ons with VAFC and it put ot 122kW and ran 13.7 at WSID in my old LS integra...

i would like to see another B-series engine with Type R bolt-ons make that much power...

im likiing this idea but am worried about the reliability side of things...

**tinkerbell** · 04-07-2005 03:36 PM

weakness:

1. thin cylinder walls due to larger bore;
2. weak rods/rod bolts due to low rpm design;
3. piston to valve clearance due to small valves in B20B.

so, using stock internals, you will not be generating sufficent cylinder pressures to risk damaging the (weaker) cylinder liners,

nor is the compression ratio high enough (~9.5:1) to really worry about detonation damaging the (weaker) sleeves,

piston to valve clearance can be solved with a hand widening of the piston reliefs with dremel or similar,

rod bolts replaced by ARP parts is best, solving the weak bolt delima,

i have revved my B20VTEC to 9200rpm a couple of times, to 8500rpm many times, over 8000rpm daily, with no broken rods, so i think the stock rods are ok, it is just the bolts that can break.

if you are in syd, pm me for a full cost breakdown...
