i still haven't started on my rebuild...i have been thinking over this for about a week now...i have decided to do the ls/vtec turbo...
i have a block from a 94 integra w/ 41k on it, the head is off my B17...i am going to start at soon but i want to know if anyone here is running it now and what i should know about it...
so far i have:
-LS eagle rods
-top end gasket set
-bottom end gasket set
-b18c water pump and timing belt
-b16a oil pump


things i need to order:
-9.5:1 B18C1 JE pistons
-cometic ls/vtec hi-boost headgasket
-inlinefour.com ls/vtec hardware kit
-ACL bearings
-ARP head bolts

i need some input on what im doing...let me know

----i know that if im going to send my block out to eagle for my block to get the sleeve work done that this would be the time...who knows how well the factory sleeves hold up, i would like to run 12-15psi daily and with race fuel crank it to 20psi...im looking at $860 to get the sleeve work done but that will delay getting my car back for probably a month...i dont have an extra car so i really need to figure this out asap!----

things i need to order:
-cometic ls/vtec headgasket / used them a few times
-inlinefour.com ls/vtec hardware kit / no need to buy this you can get every thing you need from a part store
-ACL bearings / if you work at honda you get good prices so ill just buy OEM
-ARP head bolts / for a b18c1


so far i have:
-LS eagle rods
-top end gasket set
-bottom end gasket set
-b18c water pump and timing belt
-b16a oil pump
sounds good so far

what compression ratio are the pistons
and is the b17a head a pr3 head ?

 

fyi: stock ls headgasket is just fine. I've been boosting on mine for a few thousand miles, no problems yet. You can also put together your own ls/vtec hardware kit it's no prob. All you need are earls fittings, 4an ss line, 1/8" npt to 4 an adapters, 4an to (some metric size adapter) and a tee. It's on http://www.diyracing.com

Here is the kit...$85 shipped from Summit with enough stuff....to allow a T off the oil line to connect a oil pressure gauge!

quantity- Product Number
005 EAR-300106

001 EAR-303006

001 EAR-580606

001 EAR-809106

001 EAR-981662

sounds like a great set up. Im running basically the same set up just with GE sleeves. Yes get the b18c pistons are the ones you wanna go with. As for dyno numbers I will have them in a couple of weeks Im taking the car to damonboost (polk performance). Well good luck with your set up.

 

thanks for everyones help...i still need to know about the sleeves and how well the factory sleeves can handle boost...i know it's all about tuning but what is a safe guess at what daily boost pressures are safe...and how about a block guard? i hear good and bad about block guards...

 

Dude, don't use the ACL bearings.

NO way.

They don't size to yoru crank like Honda bearings.

Saving $75 bucks on bearings, the heart of your motor is not worth it.

When ACL bearings come in every size Honda bearings come in....

then use them.

Honda motors don't know the difference between a bearing clearance of .0017 and .0018. One ten thousandth does not make one bit of difference in the life or performance of a Honda. Both are within operating variance. I'll bet there are not five people on this board who could read a micrometer to the nearest ten thousandth much less have the proper calibrated equipment to do it. Most use plastigage that you are lucky to get a good reading to one thousandth much less one ten thousandth. When you put those cheap chineese made rods in a motor, who has inside mics to see if the inside rod diameter is correct. Don't think you can just read a color code in a manual and buy the right color, put it together without checking it first.
ACL bearings always put you in the acceptable bearing clearance range. They are as strong as Hondas and I have never seen one fail in the motors I build or in other builders motors (JG, Benson, HoleShot, etc.) that I've freshened for customers.
I'm not saying ACL is any better than Honda. Their quality is equal. I am saying if you are throwing in Honda bearings in aftermarket rods without using a bearing mic, inside mic and outside mic, going only on the color of the bearing, then you are not doing it right. I am saying that it is ok to use ACL Bearings for 99% of the builders and applications described in this forum.

 

what about his oil pump choice? does the b16 pump flow the same as a GSR/ITR/CRV? if so, then i guess he's ok there too.

 

At 6000RPM:
B16A oil pump 53qpm
B18C oil pump 75qpm
I went with the B18C.

 

what about the CRV? i get the honda parts cheaper than acura

 

it is my understanding that the gsr/itr/crv oil pumps have the same flow rates.

 

my understandings as well on the CRV oil pump
...and I have had no problems with the ACL bearings, I'd use them again without any reserve

Dude, why are you trying to use stock LS rods? They're not that strong. If you're sleeving your engine and adding forged pistons you might as well go ahead and buy some beefy rods too.

Oh and you LS/VTEC oil line kit is also going to have to accomidate the Turbo feed line also. Just something to think about.

As you're prolly figured out the B17A is the blacksheep of the B-series VTEC family. It was only made in the US between 92-93. So the aftermarket support of that engine is too great. Thankfully it's nothing more than a B16 head. You'll prolly wanna dump the stock cams for some GS-R's. The B17's had a .1 more displacement than the B16 yet were rated at the same HP.

PS: GS-R/ITR/B20 oil pumpsall flow the same 74 GPM. Get one, your turbo and VTEC top end will appreciate the extra flow!

 

i don't have stock LS rods...i have LS eagle rods...i am going to go ahead and keep the gs-r cams i don't really think id see any improvements by swapping them at this point...while the b17 may be a "blacksheep" it is a strong motor that i was going to keep but im gonna try the LS/VTEC instead, maybe the bigger block and longer stroke will help the turbo spool...

 

Straight from the manual on b18a/b18b/b20b/z blocks:

"standard rod bearing clearance"
.0008 to .0015
Service limit .002 MAXIMUM.

So if the motor doesn't come out to those Standard rod bearing clearances, we make it have them.

We can't do it with ACL, they are often too loose for the .0015 standard.

I won't even bring this up again.
You can do whatever you want. It really doesn't matter.

If it works for you, it works.

Jeff

i checked today and the oil pump for the civic si and the 01 cr-v have the same part number... the delsol vtec from 94 has a different part number so is that what you are talking about?
