I have a 2000 b20 crv, and dont listen to what people say about weak sleeves and shit, i mean yeah they are a little thinner than the b18b/a block, but you can easily run under 10psi with a reliable tune... I first decided to go turbo but after summing up all the parts and work it would have cost me too much, so i decided to go with Jackson Racings supercharger for the crv.

You are not going to last more then 2000km with 10psi on a stock block. Let alone a Supercharger that generates 2X's the heat an intercooled turbo setup would.

A simple turbo kit around 8-10psi, skunk 2 intake manifold, maybe some porting, and a good reliable tune (hondata s100 or s200 preferably) with 550 injectors and a walbro pump and you can make 250-280 hp no probs on the b20.

If you can keep VTEC all the better. FI and VTEC is a beautiful thing. There are no reliability issues. If anything the motor is breathing better after crossover. The biggest problem with VTEC and FI there are only 1 out of 100 so claimed tuners that can actually tune the combo properly.

As for engine management. Before you go recomending what he should use. Ask if he is a 5spd or a 4AT setup.

I'm pro Hondata and thats what I run.

1500lbs is huge. A NA B20 CR-V is not going to see 13's without a 150 shot like you mentioned.

hey ouzu, damn man that prelude of yours makes me miss mine, i sold it about 3 months ago, I couldn't fix the damn problem it has with the key and not starting, it has a problem with the whole immobilizer unit, and i needed the red and gray keys, that the dealer wanted to fudge pack me on, so i sold it for 7grand. Oh how I miss my BB6

I have had the blower on the engine for just over 1400km now and no sign of any cracks or leaks or heat soak or anything so im pretty sure this setup is going to last me at least 100,000kms, plus i had it tuned by the best in Australia, and it is running a little rich up top to rid the detonation, and the timing is slightly lower so dont worry about me blowing any sleeves its a rock sollid setup.
As for temperature i am going to change the top mount intercooler out for a Vortech Power Cooler setup that runs air to water for extra cold air, oh and the intake temps are not even reaching 120F whith the top mount so thats pretty good...

And as for the Vtec head, sure it is a beautiful thing with turbo, but not so much with S/C, as you have to be carefull with the advance abd retard, the overlapping stage allows boost to run out of the cylinders without increasing the pressure... Im not saying that this is the problem with a stock vtec head, but with aftermarket vtec cams that exagerate vtec.

But overall i do agree with you that a vtec head is a great investment with or without boost...

damn 1 out of 100 tuners can tune boost and vtec, australia must have shitty tuners, cause I know 4 guys from here in Texas that are among if not THE best tuners in the country. Tony Palo of T1 Race Development, St00pid from St00pidfast, Kenny Tran from Jotech and Huy Tran from Inline Racing.

Don't Mess with Texas
cause
Texas is the home of players and pimpz
Texas Mother Funker thats where I stay

Man... what are you on about???? I didnt say anything about tuning silly i was talking about having a Jackson Racing blower and having a VTEC head, it is a great combo but to make more power you cant just slap in some even more overlapping vtec cams like in N/A engines, it actually helps to have less overlap between intake and exhaust unlike N/A... that is what i was saying, so its not so simple as slapping on a vtec head with the blower you have to retard the intake timing slightly for good power......

[SouthTexasImportLegend]

you are very right, just showing some love to the Texas legend Tony Palo

I'd suggest most of you 1st gener's with the B20, research quite a bit on the LS/VTEC combos (b18b).

It's basically taking the head off a Civic Si (B16) or off an Acura Integra GSR or Type R and sticking it on the stock Acura Integra LS block.

It's a fairly common practice in the Integra/Civic world.

The B20 block, is unfortunately the bastard stepchild of the B series. It's weak.

Best bet, is getting a B18C and transplanting it and then building it up.

the power output from the b18c being in the 200hp range from the factory.

swapping your transmission from the CRV 5 speed to a B16 or B18 transmission might help in off the line acceleration as well

also, for the most part, you can use parts from B series engines across the board, as well as transmissions.


The swap from a B20 to a B18 or B16, should be pretty straight forward, utilizing the stock engine mounts to install the new engine (this is a direct engine series swap, so everything is interchangeable)

I don't agree with that. A lot of honda tuners are constantly looking for b20 bases to do LS/VTEC Frankensteins. Specifically the CRV B20 blocks! I believe its because of the higher compression ratio and torque. I do however agree with getting a 5 speed tranny for the full conversion though. Stock CRV trannies weren't really built for boost or hard driving conditions.

True. Most of the reasons why 1st gens get stolen.
