i have a 88 accord hatch that i am planing on doing a b18 swap on. i have a triple set of solex addhe carbs , i know i only need 2 but the third is to play with. i alrwady have a hot rod wireing kit, i am planning on rewireing thw whole car to run with no ecu. i will be driving this car on the street, i know it wont be legal but i can get away with alot more over here in boston, i can pass smog with no problem. anyways i am debating if i want to pick up a b18a1 and throw on the carbs, upgrade the cams ect. i currently have a vtec 97 gsr head and debating the lsvtec. either way i am gonna need to do head work because of the sidedrafts. i know this is touching the touch subject on every forum of vtec vs. novtec but this is kinda under different curcumstances seeing that i wont be running an efi setup. also i am kinda new to carbs/sidedrafts so any info/links on tuning and what to look for would be helpful. the connversion is possable, even though placeracing went out of business or isent around i can still somehow get mounts do i am not worried about mounting the engine. i know i will have to use a cable tranny. i have a msd sci setup so i am not wrooried about spark. no for the distrubtor, since ill have an external coil can i just cut my distrubitor wires and get the modded cap? do the sell special hollow distributrs? ill save the rest for later. i know it sounds like i am not making any sence but if you can spend 15 mins or more to talk to me aim me : SQ is the SQUAD

i did not understand what i just read

 

ok, let me try this one step at a time.
seeing that i will be runnig dual 40mm solex carbs on a b series setup, does it make sence going ls/vtec over a regular ls setup. i wanted to go vtec, but will the vtec work good having the carbs. either way i am going to do a mild build on the head. this will be a non ecu setup

 

bump for help, com on guys

i pulled out my painless style wire harness to take a look at it. ill prob be running my autometer tach with a rpm activated switch to run the vtec if i do go lsvtec any one know the price of the manifold adapter for sidedraft to besries motor?

 

am i just asking stupid questions or dose nobody know the answers?

 

I still don't know if you would be able to crossover to VTEC, even with an activated switch.

A VTEC motor relies a lot more on the ECU than just telling it pop over to VTEC.

 

really, i was just going on what i was told. i was told you use a rpm actived switch silimar to the autometer pill system

 

Sure the switch on a VTEC enabled vehicle would tell it to switch. But it also has a list of checks it goes through in the ECU..

 

Alot of (Ghetto) people use rpm activated switches in swaps where they don't have the proper ECU to run there set-up. I am always in the EF forums and i see people doing it all the time. But if i was going to run your set-up i would run a stand alone. Easier and less to mess with. But it is also takes alot of $$$.

run the stock ecu for what ever motor you put in ...the run the carbs for fuel ..simple and you et proper timming control ...also the ecu only check for the vtec stuff because its told to ...as long as you have a good oil level you shouldnt have a problem running the switch ...
but again if you run the ecu then it will do all that ..

 

+seeing that i alread removed all the cars wiring and its an 88 accord, wiring it up with any other wire harness except the aftermarked one i already have will just create more problems. call it ghetto if you like i just cant see making a whole custom wireharness and ecu just to activate vtec when there is a simpler way. but thanks alot for replying, i was bangnig my head cuz no one would take a second to help me out.

so my next question is do you think it matters since i am running carbs sould i use the vtec head or a ls head. either way i know i am gonna have to run some agressive cams.

keep in mind this isent a daily driver car, i dont care about idle or emissions

 

LS, for "ease" of use...

You can put in crazy aggressive cams and tune the heck out of it.. And hope for the best. Atleast it will be different.

 

If you are using a 1 wire system like it sounds like you are trying to do you wont see as much hp. A VTEC ECU has two fuel maps... one for when you arent in VTEC and one for when you are in VTEC. With this 1 wire system you will only be running on the non VTEC fuel map.

 

when Bisi ran carbs on the street he kept his stock ecu in and unplugged the injectors. Since your rewiring for no ecu, just run the carbs and buy the msd ignition with crank trigger whichever one that is. I wouldn t be worried about gettin vtec to work i would be more worried about tuning the carbs for vtec. It can be done but if not done properly you can lean that bitch out and you know the outcome. An ls would be simpler and you might manage 170-180 depending on the aggressiveness of the setup. I don t necessarily think the vtec head is a bad idea, just more difficult especially if you haven t ever worked with carbs. The manifold situation should be the same as the DIY ITB manifolds. just make sure to do it right and get the correct angles, length, port match etc. otherwise be ready to fork out 200 plus for a very hard to find piece.

 

hes running carbs...when in vtec fuel need will be dependant on how fast the air is going through the venturi ...so as long as the carbs are big enough it would work fine off a switch


oh yea the msd idea is great way t do it

 

i got the dual 40mm carbs, they where rated up to a mild 2.0. i could of got 45's but its too late now. i tried contacting a webber deal;er to get a price on the flange to connect the carbs to the motor but i never got an answer. i will look up the diy for the itb cuz i havent seen it yet, thanks for all the good info and keep it comming

 

also would any1 hapopen to know the difference between solex addhe carbs and the solex phh carbs. i am stil waiting to get my book so i can read up on them
