How reliable are type R engines??

hey guys, Im planning on doing a b18cr conversion in my ek9, Im assuming the swap over will be pretty straight forward, but Im just wondering how long the type R engines are good for ? the motor Im planning on getting has 150k kms on it, been in a minor frontal. because it was half way out when I was thinking of buying it i couldnt get compression or leak test done to it. prev owner say it doesnt smoke. Im just bit worried that after doing the conversion the engine will smoke or something internally faulty. My engine has done 130k kms on it, but still very healthy and running strong.
do you think its safe to believe the prev owner in saying the motor is healthy or would you not get a type R motor unless its compression tested? if it was under 100k I wouldnt really worry but its a little high, any feed back would be great. Thanks!
 
if your that worried rebuild it, if you dont have the time or resources to do that you have 2 options:

1. roll the dice and buy the damn engine
2. be a scaredy cat and dont buy the engine.

honda engines are cheap to rebuild even if the engine does smoke thats nothing a valve stem seal changfe and new pistons/rings cant fix...
 
If you cant see it running get at least a compression test Having said that I am just having a B18C6 engine rebuilt that had 225 psi on each bore but blew oil as the oil control was poor. This is only seen with a leakdown test. I have seen knackered B18 engines with very low mileage and have also seen fantastic engines that burn no oil at well over 100k miles

But if its cheap enough so you could factor in a rebuild go for it.

An engine can have 50K kms on its back and ****ed up or 150K kms and in almost perfect condition. Is up to the owner. You don't really need to get upset from the mileage so far.

I wouldn't take it for a compression test either, just make sure to be checked on the road by a Honda specialist who can understand how much healty it is and if it's OK is ready for rock! :D You shouldn't also be concerned with upgrades, questioning Honda engines and especially the B-series is a bit funny. :nice:
 
My B18C has 120,000 km on it, mostly track kilometers, and the compressions are ok, it all depends how the previous owner took care of the motor.

In my opinion, don't buy a motor that you can't check the compressions. I prefer to buy a spoon stroker kit for the b16b. Doing this you can add some more goodies also :naughty:
 
its a hit or a miss u just got to take the chance i have seen b16 engines with 190.000 miles on it and never had a timming belt done or looked after and the car run as sweet as a nut. or like said u can get the spoon stroker kit not sure if you are cheaper just buying the parts from honda least if you do it this way u know the history of the engine
 
for my record, the B-series engine by Honda is by far one of the trademark engine by Honda and is used worldwide for all sort of purpose, drag, track, rally, although seldom in drift, the point is that its reputation are well said so, the only chance that a B-series can bcum not reliable are to be blamed by the owner's own maintenance habits, other than that, the B-series engine will do just fine, even with hard aggressive driving

I totally agree with you! :nice:
 
well I can pretty much answer this for my self now, they BLOODY reliable lol
decided to go ahead with the 150k km b18cr conversion and she runs mint. 215 psi in all cylinders
goes hard too definately an increase over the b16b, but not as aggressive transition into vtec. anyways, thanks for all your comments before.

Thanks
 
Was it a straight swap with the wiring just plug out the connections off the b16b and plug them back up to the b18c and use the b18c ecu? Is the gearbox the same? Driveshaft sizes etc.

You don't want an aggressive transition into vtec. Having this means your car isn't as fast as it should be. The transition should be smooth and gradual. Even though it feels slower on the butt dyno, you're actually accelerating faster overall.
 
yep it was a straight swap, loom was kep the same, just plugged into the b18cr sensors and ecu swapped over. now having driven it more there is definately some usable torque in 3rd/4th gear. and into vtec the sound is not as goood as it was going into vtec and transition is a lot smoother, however I have noticed I get up to speed alot quicker and dont go out of vtec even if I shift a little bit before the redline. overall Im very satisfied. now time for an exhaust and an ecu tune. should I go 2.25 or 2.5 inch with a b18cr ?

Thanks

B16B always have a hard transition over the B18C naturally, providing both cars have stock cams... Lowering the vtec on the B16B would make the transition smoother but will just create a power dip. Tuning may help but still can't beat the power figures when kicking in at 6000rpm.
 
My CR is 230psi all cylinders... and doesn't burn 1 drop of oil :D
 
If it creates a powerdip, then the vtec point isn't sitting at the correct rpm. Powerdip = not smooth. Surge in power = not smooth.

The stock rpm point is set so high for marketing reasons, nothing else.

i agree %1000 yes one thousand percent! honda could have easily made the vtec transition smooth, but then you would not feel the jolt when vtec crosses over, and that jolt is what people like... i will post a dyno soon that i have on my other computer, it shows a b16b built with no power dip at all...
 
what diameter is a factory ctr exhaust? 2? or 2.25? is it worth upgrading to 2.5 on the b18cr ?
Cheers
