abaz crvtec whats up
 

so jeff what up with the red crx did you get the crv block yet. and are you getting piston and rods like getting build.

Re:abaz crvtec whats up
 

Got the block monday, going to paint it up nice, and pin the sleeves. Also need to get the head done, so its going to be a little bit, (and fix the turbokit, lol)

Jeff

Re:abaz crvtec whats up
 

waht is pinning the sleeves??

Re:abaz crvtec whats up
 

check out the zc build in the tech section off the front page, there's a picture of it done to the zc sleeves. Basically you pult bolts into the block to support the sleeves.

Re:abaz crvtec whats up
 

also known as "posting" the block

Re:abaz crvtec whats up
 

holy ---- Jeff. You ALREADY got the b20 block, damn, you waste NO time.

You must be getting alot of donations to afford all that crap ;)

Re:abaz crvtec whats up
 

engine was only 840 shipped ???

Re:abaz crvtec whats up
 

you have to take into account, jeff's bling factor is through the roof.

Re:abaz crvtec whats up
 

aaaahhhhh to have money to burn.. lol Wish I could do that, drop 840 in a pinch

Re:abaz crvtec whats up
 

it adds up quickly though..

-Hondata intake manifold gasket
-5way valve grind
-New head gasket
-Posts/Pins for block support
-Por15 Engine Paint (maron)
-.63 A/R Exhaust housing
-Balance Injectors
-180 Mandrel 2.5 & 180 1.5 Mandrel & flanges (redoing DP)

I measured today, the stock B18 sleeves are 7.15mm and the B20 sleeves are 7.78mm I thought my eyes were fucked up, guess not, lol...

It should be nice when I'm done, a good 300whp to the ground, I'm just really looking forward for the extra torque..

Re:abaz crvtec whats up
 

wasn;t your ls/vtec for a daily driver? damn jeff, finish that ZC so you dont have to blow up your DD engines :P

Re:abaz crvtec whats up
 

Yup, the Red car is my daily driver, and I have honestly been having alot more fun with it, Once you boost b-series, you never go back ;) All my time and effort has really been into this car, the race car...... well it seems ---- just doesnt end with that thing, plus I really dont care working on it where its at, maybe if it was sitting in my garage I would get a tad bit more motivated. Who knows, maybe this year it will get done, or I might sell out, I think having a pretty ------- quick street car is alot funnier than having a built race car. Unless it was setup for road racing ;)

Jeff

Re:abaz crvtec whats up
 

true true.. fixing the car is half the fun. I've seen one place do something serious w/ a crvtec. The did some dyno tuning and cam swapping and some dyno runs but that was about it. Nothing since. I'd love to see what you can do with it.

Just promise us all one thing. Take very details pictures and memos.

Re:abaz crvtec whats up
 

theres a kid here in town with a black crx who works at nu image auto salon and he has a cr/vtec all motor and he hits mid 11's....his is stripped interior though....not a whole lot of weight...hey jeff whats up with ur interior ?? is it all there of stripped a bit ?ive got stripped from the doors on back.

Re:abaz crvtec whats up
 

i might be mistsakin, but someone told me that b20 blocks arent as strong as a b18 block. :-\ i was wanting to go with a b20 until i heard this. also would it be better to do a b18 block with b20 head, or would it be better to do b18 a/b block with b18c head?

Re:abaz crvtec whats up
 

The B20 cylinders are all cast together. The casting itself is extremely complex compared to the B18/B16 sleeves. The fact that the casting is large, with variable thicknesses and they are very brittle by comparison to their simpler round counterparts. Brittle parts can't "flex" under loads. That is also why I aided the sleeves with Posts/pins. (check in the hybrid forum for my write up)

Basically the B20 and F20c (s2000) share the same sleeve design.

12psi tuned correctly shouldnt be a problem.

Jeff

Re:abaz crvtec whats up
 

a b16a head would be cheaper probably.

Re:abaz crvtec whats up
 

and I've heard that they have better flow

Re:abaz crvtec whats up
 

Jeff is doing the opposite of me.. I would have the ZC turbo for the street, and the b20 for race only.. lol

He's going to have a faster street car than a race car.

Re:abaz crvtec whats up
 

Wut is your compression on the b20 and wut head are you using

Re:abaz crvtec whats up
 

----... I put the wrong piston in on my b-series comp calculator, I was all excited thinking I was going to raise the compression, guess not..

B20b block
B18c (GSR) head
B20b Pistons
stock head gasket,

Head has been milled down a bit, its right around 9.5 now, opposed to the 9.8 before with the ls/vtec.

Oh and get this, I went to the machine shop today, and I had 2 bent valves in cylinder #1. Now this isnt the cylinder that cracked the sleeve either. The car had always had a slight miss, and I knew it was something in the valve train... So now it all makes sense, and also why my dyno numbers were a tad lower than I expected. It should be a 300whp no problem now... (hopefully) ;)

eta is next week on this POS...

Re:abaz crvtec whats up
 

Did you say the the B18 sleeves are thinner then the B20 ones? Is the B20 sleeved, then measured?

Blaze

Re:abaz crvtec whats up
 

"I measured today, the stock B18 sleeves are 7.15mm and the B20 sleeves are 7.78mm "

B20 sleeves are larger (stock) than B18a/b's but are weaker due to how they are cast together, and not truely round like most open deck sleeved engines.

Jeff

Re:abaz crvtec whats up
 

Ah, I see. What would you suggest for a non VTEC B20, blockguard/pins (like you did) or other? Sleeving is not an option for me. I'll have GHD and some fatty 550s, 14psi? Tuned to perfection of course.
