Ok. My GSR engine threw a rod bearing. Good riddens, the thing was cursed anyway. Now, RIGHT NOW, I have the following in my garage:

B20B4 Short block, 40k mi. looks good.
B18C1 Head, stage II port, endyne springs, stock cams, cam gears, skunk2 intake
Fmax turbo kit, T3/T4 w/IC- no crazy extra injectors, tail waste gate, BOV
(4) 440 cc injectors
Hondata stage 4b
Crane HI-6 w/Lx-92 coil + Magnecore wires
Type R Tranny/act clutch/alum flywheel
B20 head (original)
93 Delsol si w/no engine.

I could probably swing another $500 on the car before my wife leaves me, so don't give me that "GE sleeve" stuff, I can't afford it. I can run the turbo at lower boost, and reduce the rev limiter, if needed. I have the Hondata for tuning. What would you do? Will this combo (stock bottom end) take 9 psi?

[Please limit the theory ****, I like driving my car, not looking at it in pieces. Don't say "well, it should...." I'll hold off on the turbo if necessary]

The car will be used for street driving and auto-x

Thanks,
Sean

I think it should easily take that 9 psi if you know how to tune well enough.

HybridKOOP

Honestly, I would suggest fixing the GSR block and maybe doing a hone on it to clean it up. Those B20 sleeves are tempermental.

hybridsol

I said the THING IS CURSED- plus the rear mount connection is cracked.

Thanks.

hybridsol

What would take 9psi? the CRVtec or the stock B20? SHOULD OR CAN? I think I'll be OK as long as I don't rev... like 7000 Redline. But w/ CRVtec, the CR is like 10.7:1 (my bad math)?

The CRVtec should take it. I think people have been cracking the b20 sleeves at 12 psi, but I could be wrong.

Thanks

Not to be a rod, but don't both with a B20 unless you wanna spent a lot of money. I dont care what everyone else says my B20vtec is a pit. Even if it's put together right you can never use that head on another block with out worrying about those four extra holes in it that you had drilled in it. I like those cams though. If you can afford the B20 block (unless you already own it) you can afford those sleeves. If not you can sell me the GSR block so you built up that B20.

edit: Oops my bad by time I got down to the bottom of the I forgot the post

???

I am lost here

Umm, yes, well. That didn't help at all. Maby I should do the old "build up then blow up then bitch about how Honda sleeves suck for turbocharging".

Seems to work for everyone else.

BTW I'll sell the block to anyone. $500+shipping. 1 spun connecting rod brg. 4 bad bores. block gaurd that's never coming out. cracked rear mount connection. no oil pan or pickup. no mounts or brackets. no dipstick. stock flywheel. Don't all come at once, please.

Yeah to make the Ls/Vtec or Cr/Vtec you have to tap holes for the heads oil line and to run the head bolts. At least on the B16a head you need the bolt holes. I made the mistake of buying a B20 and Vtec-ing it. It'd would be better to just have the GSR block sleeved for 84mm pistons and build it up. The Vtec engines are just stronger than the B20s. I would sell the B20 you have and use that money to sleeve the GSR. Sorry if you can't understand my English. You can always make more money.

Just my opinion

I dunno where the **** this guy's drilling holes... you need to counterbore 2 holes to accept the locating dowel pins on the cylinder head and plug one oil orifice. Removing the 1/8 NPT plug in the oil orifice will restore the vtec head to original running condition. The counterbores will have no effect if you decide to use the head on another B18C block since the dowel pins would be back in their original location.

Anyway, that's not what you're asking.

I'm currently running almost exactly the setup you describe. B20B STOCK internals, B18C head, 8-9 psi, AEM EMS with rev limit at 7500. Smooth as butter, I'm on 450 injectors and running 11:1 AF under boost right now so I'm tuned conservatively and the car feels just about as quick as I want it. I briefly tuned it up to 12:1 with slightly more aggressive ignition curves and it was just impossible to keep power to the ground, I backed it off a little after hitting the end of a right-hand off-camber sweeping onramp riding the rev limiter in understeering wheelspin in 3rd gear as the car slewed into the entry lane. Yeah, it was only the 2nd or 3rd day I'd had the turbo in and I mistakenly "just punched it" to merge into traffic like I had been doing without the turbo. So I know tuning can bring a little more power out of it but I like it being safe and having some headroom. I do however KNOW my B18C head is slightly warped so I can NOT keep a seal at the head/block interface which is causing some gradual overheating difficulties, but that has nothing to do with the B20/vtec configuration. This was going on before the B20 block came in (I also spun a rod on my GSR engine and damaged the crank enough that it was cheaper and faster to buy a B20 longblock and swap it.)

Now that's a reply! Thank you so much....

BudaKai

Sorry if I didn't make sense that'll teach me to post while intoxicated. Hell I don't even know what I was talking about.

iTrader: (1)

if I was in ur situation I would put in the B20 block, w/ OUT the gsr head. boost it to 10psi have fun with it and start putting together a built GSR motor. But if all u want is a stock block B20vtec boosting 9psi then go for it, do it right and u wont have any problems. just remember, its expensive to do it right.

dbman96

I'm honestly about to do exactly what DIRep suggested - with my GSR head warped, I can swap in the B20B head that's sitting in my garage, drive the engine as-is (VTEC isn't making THAT much difference under boost, particularly with a low rev limit) and start fixing / building up the GSR engine in the meantime.

highbrid

i would build the gsr personally, which is what i am doing. I used to have crvtec in my car but switched back to a sleeved gsr. What someone said before about getting a gsr sleeved to 84mm is a better idea than running a crvtec in my opinion.
