1.7lciviclx2001

wondering how (if even possible) to make my 2001 civic lx (with a D17a1 non vtec) a vtec... what parts do i have to buy to make it a vtec? just a head and computer? what head or computer?

ALSO what internal parts do i have to upgrade to run a 20psi turbo??
can i even run 20psi on that motor?
whats a good amount of psi to run?

Please reply... even if somebody said what you were gonna say

You do realize that you will literally get nothing going from a D17A1->A2, right? Unless you're doing this for experimental purposes. The major difference between LX and EX is:

1. Gearing - EX tranny has slightly shorter gearing for acceleration but it's not that great (suspect it might be somewhat better in the higher gears)
2. Top speed - EX is slightly higher, not electronically restricted
3. Higher compression ratio on the EX

While it's very possible, the only noticeable difference is the top speed. The VTEC crossover is silent since it is SOHC VTEC-E @ 3,200 RPM (if I remember correctly). Dunno about the A1, but when running an intake, the A2 gets noticeably louder after 4,100 RPMs. The real price of going from A1->A2... is the price + decreased fuel economy.

It's been a while since I've kept up with what's available for the Civic as far as boosting goes, but still... based on compression ratio, the A1 would still be the better engine to boost?

if i were u i'd simply swap the engine. the K series is a bit pricey, a b16a2 would be good for what i think u are trying to do. also 20lbs of boost is kinda high for a civic. correct me anyone if i'm wrong, but i think i remember something to the effect that if u go over 8lbs of boost on civic u need to start changing internals ex. cams, pistons and all that. hi boost means hi mods, bigger intake, headers full exhaust the works. but if i were u i'd jus drop a b16 in with a nice intake and exhaust system, a nice turbo making around 8-12 lbs of boost and call it a day. i dont kno anyone who ever boost the d17's, they're kinda lame the d15bs hav higher stock horsepower than those ( jus t a thought)
i hope this helped

lobomic

oh and the easiest way to make ur engine vtec would be to change the head to a vtec head with the solenoid

1.7lciviclx2001

i was told B series engines are illegal for a 7th generation civic... because there older less efficient engines.. but i swap one anyways.. i found a really nice b20z2 complete swap for $5300.. but i just want to have some more horsepower with out having to do a whole engine swap

1.7lciviclx2001

idk how hard it is to do a whole engine swap.. a couple of my friends are mechanics, and i know my way around a civic pretty well.. so i may try to do a swap myself for an experiment

I hate threads like this on this site. All the tech heads have left and those that are left....well, yeah.

VTEC head gives you cam options. Best reason to switch.

As far as boost, look at all the links in my sig. Specifically the one at the bottom.

1.7lciviclx2001

what do you mean by that? you have a better website?

unTuned

i hate threads like this too. you are doing no research and you are asking questions that give me no confidence in your ability to do a swap. do you know what is involved? if this car is your daily driver, 'experimenting' with trying to do your own swap is going to be a very bad idea. especially if you have a good running and untampered stock engine that has zero problems.

also, if youre serious about boosting and going high with boost, you dont even want a d17a2. you want the non v-tec lx/dx a1 which you already have.

for a good basic turbo setup with stock internals, you are looking at spending $3k or more and that is only to run 5-7 psi. if you are going to get into the 15-20ish psi area, expect to be spending $10k or more for a good turbo system and having a whole **** load of other things done (this is all also considering you are very mechanically knowledged too). by that i mean not just internals, but also many of your suspension shafts, bearings, etc etc. possibly even more braking power with a 4 wheel disc conversion.

i dont have a limit in money. im a penny pincher, but if i get stuck on something i can pay for somebody to do it..
not a huge turbo, but its $600

unTuned seems to have a pretty good idea on how this boost thing goes. If u go beyond 7/8 lbs of boost u gotta be willing to go the whole way. and like he stated , ur gonna need to upgrade almost everything... its all up 2 u tho. more than 8lbs of boost means you are at level 2 and stock components will fail

1.7lciviclx2001

ik... what i first asked was what are all the parts i have to replace with level 2 parts..
just give me a straight answer non of the ect ect crap

Don't buy that crappy kit you posted. It's an Ebay kit and is junk.

Yes there is a better website where a lot of boosted 7th genrs are. We have a good F/I section with a lot FAQs and stickies that answer all of the questions you're asking.

For a high boost setup you need rods, pistons, standalone engine management and a fuel system that can feed the new requirements of the engine. We typically convert the fuel system to a return setup with an upgraded pump and an adjustable rising rate FPR.

And you don't want an A1 for high boost. The only EMS that works on a non-vtec motor is AEM. Stick with an A2 and get kpro.

How did you know it was ebay?? did all the jdm parts give it away?? cause the first jdm i saw i thought oh crap this kids on ebay tryin to destroy his motor and i just gave up on the rest of the post

and to the OP if there is the slightest possible chance in hell that you would get "stuck" on something then YOU SHOULDN'T BE DOING IT!!!!!!!!!!

Huh. I never figured you for an *******. Learn something new every day.

JagerVR4

i have a fully built B18C block with a B16a head (head is stock other than springs and retainers) garrett .70a/r, 1000cc injectors, etc. im running 17PSI. but my tuning is limited due to the fact that i have Hondata S200.... in about a month im going to move up to S300.

it takes alot of cabbage to get these motors to handle over 15PSI and have it be drivable on an every day basis.

but if and when you do upgrade to whichever motor and plan on going turbo. for the love of god make sure you do it right, **** that ebay ****. spend the extra cash for the good stuff. it is completely worth it. and make sure you have some nice headstuds i just put ARP studs in mine the other day. head lift is a bastard....

I have a 02 Honda civic ex with a D17A1 in it. I had mine dyno tested and I am pushing 220hp. But I have the ECU Chipped, DC sport headers, Full Megan Racing Catback exhaust, Skunk2 stage 3 cam, AEM ColdAir Intake. And this has been dyno tested and I couldn't believe I had that much. concidering it was 128hp stock. But I am also saving up right now to a F22 vtec from a S2000.

Thank you for contributing to a dead 3 year old thread

Brandon Gappa

There is no way to run 20psi I believe because the block is aluminum

Colin42

this is from 7 years ago....

Actually, there have been members that ran boost that high. Highest I saw from a member here was 31psi. The current generation Honda still rocks aluminum blocks, and the Si and Type R's rock boost pressures in excess of 20psi (20.3 and 23psi, respectively). With KTuner, my 2018 is rocking 21psi, still with that aluminum block.

Yeah, I'm contributing to an old *** thread. Fight me

I run 20psi with 1000cc injectors on E85 all day long...well, when the engine is together.
I do have a block guard but i'm running stock sleeves.

I'm content with my 21.5psi at the moment, but I appreciate the offer and love every time you update your build thread
