I dont know if this the right thread but, I am the type that will get a car and do modes to it, this is my first Honda to own to work on and learning, I did some research and I know the EX is limited compared to the SI, Hondata is in my future.




What I have done so far is

-header

-Cold Air (to the bumper)

- Stage 2 EXEDY clutch, 6 sprung, lightwieght flywheel.

- opened the exhaust




What else can I do, can I get a bigger manifold? can I get a throttle body that will compliment it? What about a short shifter? I look but I can't seem to find the right bolt ons to a EX and pretty ignorant on it.

 

Hondata isn't needed until you either build a high compression, high rev naturally aspirated motor or do forced induction. A short shifter and a good suspension is all an EX needs to feel great. The B16 in the si isn't all that great either. If you want to swap it there are good options like the B18C1 or the B18c3 or even an H22. I wouldn't. A D16z6 is a great engine, revs nicely, is simple, is light ..

 

So theoretically the stuff I’ve done to it is pretty much the max I can do to it ?

 

There are other things, but without touching the motor guts - yeah, IMHO.

 

Thanks a ton. Saved me a lot of money and headache

 

On a side note, I was hard on a exedy stage 2, but with your advice I won’t get that. Do you recommend a good clutch?

 

there is the skunk2 intake manifold and 2 different size tb that will fit an ex. i was told however it will need hondata after that as it wont idle right if at all and the a/f will be off. not cheap tho and its not really big gains. only option for any real gains is a real na build or boost. poking around close to 200 is possible on an na build but your looking at serious bucks. same deal with boost but if you keep the boost low you can do without internal upgrades. so if you diy handy you can do the install yourself and get it tuned for less downtime. all depends on how much power your after.

 

oh if you do decide to go after the intake manifold and or tb make sure you READ the item description as they technically have like 4 or 5 that are d/b series listed. only 2 of them will be a direct bolt on the other 2 are a different setup and are meant for custom builds.

 

There's literally like close to no gain from a bigger TB/IM combo on a D-series without head work. Not that head work is expensive, but you do need to get that porting done. If this was my build it would be a D16 block with H-rods and lightened/knife edged crank, high compression pistons, bunch of head work, cam, followed by header, intake manifold and throttle body, put on a flow bench and worked on... not cheap by any means. This is the point you need a standalone, but it's a simple engine, you can do a megasquirt if legal where you are. You'll need a fuel system upgrade too. The $/hp on a build like this is pretty high.

thanks stiffler i forgot to add that about the tb and intake. most ive really been told is it helps throttle response a touch and gains are definitely minimal. the tb and intake manifold cant pull in anymore air than the head allows. it is something you can scoop up if you already plan on hondata and eventually actual engine work. but if you dont plan on doing any engine work or boost dont bother with it.
