Rendon Lx-I Boosted Sedan Build

[AccordEpicenter]

well it lasted for awhile boosted. i was hard on it to...SO im going b18 pistons wesico and eagle rods. head is going to get ported and bisi springs and keep my cam. So ill going to try to get the block in this month to the shop. my goal is 300 for starts.

POS? o hell no.

hmm b18 pistons? umm

[Rendon LX-i]

yes sir. Same as 89t setup. any b18 a/b 83mm pistons and any b18 a/b rods

[Tdurr]

wut bore would our motors be if its bored 20over(like me and luke HA!)

[Rendon LX-i]

83mm

[stephensimmons]

wut bore would our motors be if its bored 20over(like me and luke HA!)

It would be 82.720

[Rendon LX-i]

stock. BUt if you want to put b series you need to get 83mm pistons then have the block bored to 83mm

[mushroom_toy]

wut bore would our motors be if its bored 20over(like me and luke HA!)

Because Im a pimp.

[MessyHonda]

so you would have to bore it out .30 mm from the stock 82.7mm

[-$MOKIN-]

I just watch the video of u guys dyno'n .Very cool . . .

[Tdurr]

sweet thanks. i gotta get another .10 bored out then i can do 83mm b series pistons.

[Rendon LX-i]

gOT MY MOOOTA today. thing is dirty but minty fresh. I got to swap all my parts over then obd1 the thing to not blow it up this time LOL. So tommorow im hopping to drop everthing in. and running

[AccordEpicenter]

okay but how does it work out with the B18 pin height and compression ratio? I was told they were different from a20...

[Rendon LX-i]

Ask 89t his setup runs good an he hasn't had any problems.

cricket's, Dam Rendon you really know how to kill a thread. LOL!







I have some eagle H beams i can compare to a old set of stock rods, but as far as the pistons go mine are dam near a flat top , pretty close to even with the deck or top of the cylinder. with the H beams.

[89T]

who told you that? The reason i ask, is because nobody that I know of has ever bothered checking.

[Rendon LX-i]

well im not worryed. your setup is worryed so im ready lol. .....SO how i kill my thread LOL. o i know. i mentioned you huh LOL

[89T]

You figured it out LoL...

Ok the OEM rod lenth from inside wrist pin to inside crank with out the bearing is

103mm

The eagle H beam is a bit longer at

106.04mm

the pistons I cant give any numbers on seeing that their in my engine.

If there is anyone with a b18a piston that can mic the top of the wrist pin to the top edge of the piston and add it to the post.

stock Is:
19.90mm
from top of wristpin to top edge of piston.

19.99mm wristpin

H beam wrist pin size:

20.94mm

now if we can get that final measurement we can see if there would be a differance mechanicaly or see if it will wash.

[89T]

I have a new pic, plus i need to edit the numbers... battery was dead on the micrometer.
numbers were updated in the post above.
when I get a chance i'll incert the numbers like before.


Rendon, if you want i can delete these post's and start a new thread.

[Rendon LX-i]

NOPE....sounds good. I need this info. there slighty taller but that doesnt matter......

So how far it sticks up when its at tdc?. i wouldnt imagine it would be much. Be nice to have a pic but you prolly wouldnt have one

No i do not have any pic's, I just searched over 400 of them. they may be in a different hard drive....somewhere


Some info from one of our own members, posted at PP.

All the B series info is here:

I also found this:

However, in working the numbers for a stock B18A I can't get everything to add up right. I suspect the B18A/B claimed deck height is a little off on the TI site.

Anyway, the number you're looking for is the compression height, measured from the center of the wrist pin to the top of the piston. For the B18A/B it's 29.97mm. From my own measurements of the higher compression A20A3 pistons ('88-'89 Accord) I get a compression height of 29.77mm. So the difference is 0.2mm (0.008") with the B18A/B pistons being slightly taller.

Trying to figure out the compression ratio change:
The extra 0.2mm would remove about 1cc assuming an 83mm bore. The stock B18A/B dome volume is (supposedly, from the calculator above) 3.2cc. I've estimated the A20A3 dome volume to be 5cc (from my own measurements). So the total change in combustion chamber volume with the B18A/B pistons is -2.8cc, for a compression ratio of 9.8:1 (assuming an 83mm bore).


Of course keep in mind that these calculations are just estimations and not hard fact. Over all I would say that switching to B18A/B pistons will probably give you a slight increase in compression ratio but probably not enough to make any significant difference.

Another factor to consider though is weight. If the B18A/B setup is lighter it will rev up faster, possibly increasing effective torque to the wheels (as opposed to actual torque output).

very good find. i completely forgot about checking PP.

[Rendon LX-i]

Old motor is out took the crusie out to damn bluky an looks cleaner. Swap over all the parts to the temp motor. So all needs tobe done is drop it in. Going to clean up the engine bay a bit an drop it but the hard part is done. Pics to come

[Tdurr]

rendon is doin work!

[Rendon LX-i]

Lol yes sir. I had a crew of 4 helping me an my builder/tuner was doing all the head timing stuff

[Rendon LX-i]

My tuner/builder is taking the timing belt shit off and swaping it over to the block im working on which is the temp motor.




So heartless



BOut half way....NOT



Motor is complete now just didnt show any pics...LOL
