ive got a 91 ls sedan that i plan to build for na with hopes of going lsvtec in teh future. so for here is the set up ive come up with

.25 over b16a pistons
shotpeened LS rods
machined b18c1 block girdle
ballanced bottomend assembely
cometic head gasket
crower valvetrain
crower 403 cams with adj camgears
hondata stage 2 or s200 with stock injectors
and a dc jdm 4-1 header with a testpipe

tell me what you think, im hoping to make 165whp and 130lb ft @ 8000 rpm

what i want to know is if i can use the valvetrain from a type r or portflo inners with ITR outers.

tia

where can i find the best deals on teh acl bearings and arp rod bolts and head studs

Sounds pretty solid to me.

I'd not mix and match a valve train for this application, unless perhaps you already have the parts. The recommended Crower valve parts are not very expensive and you won't be left scratching your head if anything goes amiss. You'll know who to blame...the installer. J/K

I got ACL bearings from Earl. Contact him or Rocket on H-T and they'll set you up.
The ARP parts I got from:

Whom I've had very good sucess with. Good luck bro.

 

uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.... all that work and only 165 whp? I would SERIOUSLY think about what you are doing here before I did it. Is this really the BEST use of your money?

Ben

 

save ur money for either an H22 or B18C swap if u plan on staying all motor

 

Or why not a Crower Stroker kit??? with those mods??

 

Uhhhhh...that's about a 45 pony jump in HP, assuming he gets 165whp which isn't totally unreasonable with that setup. It's not turbo territory, but it is JRSC like gains and for less I should think.

 

Why's everyone always so quick to suggest a stroker kit?!? I mean this is a b18b w/ a stroke of 89mm...not a b16a w/ a stock 77mm stroke. A stroker kit would cost a whopping $2300 min. and give him a totally cruddy r/s ratio, raise piston speed, and shorten engine life. All that to raise displacement 124cc. Pass. Sleeve it to 86mm for a displacement of 2068(+234) and forged pistons for $1350 LONG LONG before you stroke it. Heck you could just about swap to a b18c bottom end, and sleeve that for the cost of the stroker kit. Stroking is a decent option for a b16a using b17a parts...in almost every single other application it makes no sense for a Honda.

 

well considering im only going to spend around 1500 to 1800 total on this i think it is a good use of my money.

40-45whp for 1800 is good, people spend 2300 +- for the same power, and about 3000+ for a turbo that makes 210whp but wont last that long because you will eventually turn the boost up and blow the motor and have to spend another 1000 rebuilding your block.

and when i get my b16a head with skunk2 valvetrain and stage 1 cams, retune the hondata, ill make around 190-195whp, so for 2800 ill have a 190+ whp 135+lbft lsvtec in my 91 sedan that will run 13's at the track, and it will be a sleeper.

 

Well I'll be about the last person on h-t to ramble on about the virtues of an LS/Vtec setup, but it sounds as though you've done your homework and your expectations aren't unreasonably, so I'll just bid you good luck bro.

 

i dont know too much but wouldnt itr pistons be better for a ls/vtec set up? just do what you want as long as you enjoy what you are doing good luck and have fun

 

my only question is if i get the hondata s200 will i need a obd0 to obd1 conversion harness? also will the hondata be enough or would it be a good idea to get an aem fuel rail and fuel pressure regulator? and are the stock injectors good enough for my set up?

oh yea, what ignition do you guys suggest?


forgot to add that i will be miling the head .20 over to achieve a compression ratio of 11.4:1

the problem with the ITR/Ctr pistons is that you have to shave off material from the ls rod if you want to use them, why do that when you can use b16a pistons for cheap, and mill the head for like $30 and ed up with a good compression ratio for na

if ur limiting yourself to a certain budget or only have so much money to spend, the best mod you can do is to your bank account namely making it larger before you start modding, you always should have a good chunk of change in hand in case something happens down the road, unless of course its not a dd and you have something to get around in in the meantime

good motto is whatever you plan on spending, double it and then start

 

if you do your homework, use quality parts, get the work done correctly by someone knowledgeable, then you will have no problems and wont have to double your budget.


can someone answer the question about the hondata and the ignition.

thx

 

No need for an AEM fuel rail. A B&M FPR will be fine. Stock injectors will also be fine

Stock will be fine


Try not to mill the head unless you really have too. I would be concerned with the valve reliefs

With all the money you are spending, couldn't you invest in a b16a head with some TypeR cams? I hear you can make 190+hp with Type R cams.

ttt

 

come on even fully stock cars have problems from time to time and when modified no matter how well you do the work there will be problems and when problems arise with higher powered tuned cars the problems are usually much more catastrophic than witch stock vehicles

i doubt there are very many companies who make parts with more quality than Honda, as well as tuners who know how to put an engine together better than the guys at Honda, also higher performance means shorter life span especially when youre revving well past stock redline

im not saying dont do it but just have yourself a good emergency fund if something does go wrong, and first anf foremost get the best damn tuning you can thats the best insurance policy

 

I believe you will need an OBD0 - OBDI harness. A P28, P30, or P72 ECU for you Hondata. I'm using a P28 w/ Hondata S200 w/ my '96 and did indeed require an OBDII - OBDI conversion harness. You can contact Hondata directly to verify this prior to spending $$$s.

I don't care for head milling since it cannot be undone, I'd rather see you get a thinner head gasket to bump compression, but it's your choice.

 

Sounds solid to me! Check your IM. -Greg

 

you should be able to hit that no problem, BlueTeg here has 150+whp with 403's and stock CR.

 

thanks alot, all my questions have been answered, all i have to do now is start buying the parts.

ill post the dyno charts up when im done.

 

tuning will be done by the same person who tuned Christian's lsvtec and crvtec so i dont think tuning will be a problem.

 

Kewlness...love to see em. Good luck.
