hello my buddy got a civic with a b21a1 he wants to know some things

[smokeymicpoter56]

what vtec head can he put on it and what dose he all have to rewire and can he just use a msd switch for it? im wanting to know about the GReddy E-Manage. what can it all for a d15b vtec motor and can i change things win im driven with it link'd to a laptop and and how many computer's dose a car really need? and is greddy a good brand to get i have heard there good but for turbo's more?

The b21a1 is a completely different kind of motor compared to the b16a, b16b, b18a, b18b, and b18c's. I find it strange that he's even got that engine in his Civic at all.
I don't understand the rest of what you're asking. No offense, but maybe you should not smokin' The Pot before typing. Are you asking if you can use the greddy e-manage with a non-turbo'd car? If that's what you mean, then I believe you can use it. But for the price of it, the software you need to play with it yourself, and any sensors you may need; it's going to end up costing way too much. You'd be better off with Hondata. And I hope you've got some work done to your car or else you're just blowing $ on something that may net you a few hp.

I heavaly doubt its a 3rd gen lude motor in your friends civic. There is no b-series vtec head compatable. The b21a1 is the odd ball of b-series engines. Not much parts(big stuff) that is interchangable, Its mounted on a bad angle, the block config is not good also. If he does actually have this engine, the best thing to go for the FI route! Just my 2 cents!!!!!!!!!!

[Hybrid1990crx]

you acutally CAN put a vtec head on it, but it recuires a ton of machine work, and in the end, not worth it.

[smokeymicpoter56]

he dose have b21a1 we have had soo many problems because of it
and he has a lude my bad i didn't see i put civic i was thinking of mine.
soo what can you put in that lude its a 91 and he wants vtec can you put a b16 or b20 and put a vtec head on that
and dose it matter waht b20 you get?

where do you get hondata at?

Ok that makes more sense. And yes it does matter what B20 you get, they are all different. The B-series he has in there no is different than the other b20's from the CRV. The rest was already answered.

For Hondata, check out www.hondata.com

It all depends on how much you smoke. Last weekend I smoked way too much and I was literally at a 10 yr old mental level. Those gravities will kill ya.

I don't think I could ever smoke enough to want to spend $1000 on ECU-managment for a stock motor. EVER.

Smokey - There's a lot of better places to spend your money before you start worrying about needing to tune it with a computer. Spending a bunch of money so you can hook your car up to a laptop when you're not tuning for a serious NA or boost aplication is a serious waste of money. Just find the right ECU for your motor and use it, if that doesn't work, find someone who will chip your ECU for you or something but I wouldn't spend the money on something to tool with it yourself.

Also, I really think the older ludes B20s won't even fit in our generations of Civics? Are you sure that is the motor in your friends Civic? If it is a B20A, its going to be a shitload of work trying to get a VTEC head on it, as been said, it's considerably different than the new B20s are. I remember back in the day a guy on H-A.net did it, but I don't haven't seen anything on it recently.

Again, google is your friend.

LOL very true.

I think he said that it's in his friends Prelude, and just madew a mistake by saying the engine was in a Civic...not sure I read that correctly though.

[smokeymicpoter56]

ok my civic is going to be for autocross and im building it all up na vtec and i dont want to spend money 2 times on parts so im buyin the right parts first time and i like the greddy stuff and i look'd at hondata and its the same price i can get the greddy stuff new. and if my friend gets a USDM B20A5 can you build it and do a vtrec head or is that motor just like the b21a1 and harder than shit to build?

we can get a that b20 for 100 for every thing soo we need to know fast were thinking about getting it 9 am.

its just cool to have a laptop put in my dash to play with my car win i drive. scare the little kids to death win they want ot race and i turn it on to get ready lol.

and i only smoke the greens some times. that first post i had smoke soo much i didn't even remeber i type that.

plus they dont even have a chip for a the pr3 its to old soo i can't use hondata.

[CivicSpoon]

The B20A5 is just like the B21A1 (and the B20A3), they are the black sheep of the b-series engine so to speak. The B20's that everyone talks about are the CRV engines.

As for your car. How far are you going with the all motor? If you go with higher compression pistons, I/h/e, and some cams; then the engine management will be worth it. But if you're just going to add basic bolt-ons or basic bolt-ons with some mild cams; then save your $ because an engine management will be over kill. And with an engine managment, the only thing you'll want to open the computer to play with is to simply switch to a second setup. Just tweaking settings while you're driving is a horrible idea, especially if you're not trained to do tuning. And if you want to tune Hondata yourself, your cost are going to look like this:
$295 for the basic Hondata system
$50 for datalogging
$200 for the ROM editor
$180 for the Programmer program
So with shaddy math it's going to cost you around $725. Then you'd have to buy a OBD1 ECU that is compatable with Hondata and convert it to work with your engine (being OBD0).

Not to be a prick, but having a laptop just to "scare the little kids to death" is a pretty Riced thing. It's just like people who put those fake blow off valves speakers to make people think they have a turbo. So basically you're just going to waste your hard earned $ on something to make people think you're fast instead of spending it on something that will make you fast. That $1,000 you'll be spending on a Hondata could be better spend on actual parts. I just think you should really think about this before you go and decide to make an unwise choice. Like you said earlier, you want to do it once and do it right.

[CivicSpoon]

Now that I thought about it, you should do a google search for Uberdata.

[smokeymicpoter56]

weel see all that hondata cost about 800 i can get the greddy stuff for 500 new and i do plan on doing cams full build i want to see the vtec turn on i well keep going more and more tell i can feel the vtec turn on. im going to do zex stage 2 cams and win i put that in im going to do some springs and valves and je pistons and eagle rods and do 11:1 on the pistons soo. and no rice kids can't pay the money to have a laptop run there car and i want it to work and be wroth it not just for show like rice kids with there 7" lcd screen with there car on it and not do anything but i do hear where your comin form soo in the start of buildin it might not be as wroth it but in the end its going to be and my buddy owns a shop for speed cars and well show me how to run and change thigns with out hurting stuff i wouldn't jsut plug in and start change the stock stuff. thanks for all your help and were can we get a jdm b20 or crv b20 thats wroth it? and well the us b20a5 well that head go on his b21a1?

Try and locate a b20z, if your doing a vtec set up on a b20, use the b20z

B20A5 2.0L DOHC non-VTEC 87-91 Prelude 2.0Si 135hp
B20B 2.0L DOHC non-VTEC 96-98 CR-V 126hp
B20Z 2.0L DOHC non-VTEC 99-01 CR-V 143hp
B21A1 2.1L DOHC non-VTEC 90-91 Prelude Si 145hp

[SiZ]

B20Z or B.
