I was just wandering what kind of cheap and easy hp/tq upgrades are out there for a vx? I have an EX intake manifold but I need a tb

92b16vx

B16A

The King

put an ex/si intake and exhaust manifold , and you will gain a damn 9 hp its well worth it , dyno proven too ad more when you run it with p28 and adjustable fuel pressure regulator

i put a p28 ecu into a vx, it threw a code for some weird reason, but it pulled a little harder plus it reved higher., but other than that b18c-typer

D16Z6 transmission is the best mod you can do to it

That motor is never going to be super strong. The block is weak, as are the rods. Just get the power to the ground a little more efficently and you'll be a lot better off.

Echo that.

The Si/EX tranny will be the best mod.

If you are on a tight budget I'd just do either a D16Z6 (92-95 Si HB and EX 4DR, 93-95 EX coupe) full engine/tranny swap, or get a JDM ZC SOHC VTEC swap.

As Ricey stated, the VX engine is just weak - period.

ahhh crap. so doing a junkyard turbo setup is pretty much out of the question then? im in the same boat as the original poster. i won't have the money to really do anything big to this car for a long time. i was planning on making a turbo kit for it peice by peice over the summer, and have it running by next spring. my life sucks.

I would never ever boost the VX engine. The rods/pistons are so weak I'll bet that 5psi could easily destroy the engine, especially untuned.

FATBOYeg6

damn, well that throws my reasoning out the window. i was thinking that because the engine is designed to run lean in low rpm's it would be built stronger. so much for that logic. im really glad i found this before i put a turbo on, becuase this is my only transportation. thanks.

Just a note - the block/crank/rods are the same as the JDM D15B SOHC VTEC. Don't completely discount the Z1 - it just needs lotsa love and most parts from a Z6 to make it a nice little performer. Rods are longer (137mm) and thicker (don't have specs...yet) than the other 1.5L - not counting the D15B. Good r/s ratio with the shorter stroke and longer rod length. Here's a pic of the VX/D15B rod (P08) left vs. a B7 rod right:



Transmission would be the best upgrade, as said. How far you want to take after that it is up to you -

Finding the best pistons for the combo would be the hard part - Z6's have been rumored as an option along with D17 GX (high comp.). No one I know has slapped this combo together - yet. A few are in work though.......

Z6 swap will be a good platform for you to build on. It's less expensive than a junkyard turbo setup as well.

Btw, those rods look like toothpicks.

civicminded92

But they are larger toothpics

Sure they will limit ultimate output - but just because there not the "best" doesn't mean that they wouldn't be good in a specific application. If you are shooting for over 200whp, look elsewhere.

This would be a good little N/A screamer/commuter built right -

N20 is right out.

so a d16z6 would be pretty much plug and play in a 95vx using the d16z6 engine harness. i searched for a little bit, and thats what i came up with. can someone confirm that. my next question is, can a z6 handle mild boost form a junkyard turbo setup? most likely a t25, or 14b DSM turbo, at like 8 psi. higher if it can handle more. thanks for the help. i want to apoligize to the original poster for thread jacking, but its about the vx, so i think it will be ok. if you would like me to take this to a different thread, i can.

edit. if i buy a jdm d15b longblock (motor, intake and exhaust mani's, injectors, fuel rail, throttle body, alt., dis., and tranny) what else would i need? the only thing i can think of is engine wiring harness, and a ecu to control it.

im on the same boat also...thinking about doing some minor mods to my vx but kinda low on the budget. How much would i gain with a ex intake manifold? would the gains also be noticable? thanks

Dude I'd do the tranny first and foremost.

Make all the power you can with the D15Z1, but that VX tranny will still kill anything resembling acceleration.

i just got done with my homemade turbo setup for my 94 vx.running 5lbs on a straight t3 .60 .48. fmic, and 450s and VAFC. runs strong. pulls hard.dont under estimate the Z1

nice job

Would like more on this... this is the same as a JDM D15B, correct... any specs? where to pick one up?

ninety9ex

also, how hard would it be to put a 97 d18y8 in this car?

basically u need to switch out everything but the head.
get z6 fuel rail. manifold. tranny. p28 ecu.
i put a p28 on my vx when i had the vx engine.
and it pulled when it hit vtec alot harder then when the vx ecu was in.

No, it's a 1.6L JDM version of the 92-95 D16Z6. It simply says "ZC" on the block, but it is a SOHC VTEC engine.
