Doing an all motor build and was wanting to hear people's take on what size throttle bodies their running and why

 

4 x 54mm throttles, becuase I want too.



Not to mention they sound F#@king sweet

 

74mm TB here, because thats about the max a JG Victor X can be bore out to!

 

What buil are the itbs on? And race or dd?

Also what build is the 74 mm throttle body on and why did you choose that size?

 

set-up is in signature, wanted the most volume I can get with the Victor X

 

Nice build, great numbers. I'm looking to be in the mid 200s hopefully, and you signature Says you port heads, whats your location?I've been looking into getting mine done for my build

 

Help us help you. Give us some specs of your build.

 

Well I have an Lsv now but redoing it do to bad oP and looking to up the cr a little and get some head work

Here's my build let me know you take

B18a stock 81mm bore
Stock ls crank
Ls rods with arp rod studs (thinking o getting shotpened no to sure yet)
B16a pistons
B16a head port and polish
68mm blox throttle body (thinking of going larger hense the thread lol)
Blox Im port matched
Hondata intake gasket
Thinking blox valvetrain
Still looking at cams but thinking s2 t2's
Homemade 4-1 header something similar to the bisimoto v2
Ctr pulley
Rc 350cc injectors
Aem cam gears

How does it sound so far?
And still looking for someone who chips obd0 ecus

 

Your TB is absolutely fine, not sure why you would want to change it..the camshafts selection you are thinking of as well is spot on..that is the mod you should be striving after not the tb larger..

 

Okay what do you think would be a good cam for my setup? And thanks I've been doing a little reading I was just thinking maybe a tad bit more air couldn't hurt lol

 

You need to put your money on

1) your engine management (bye-bye OBD0, seriously...)
2) The power level you're looking for to pick the right level camshafts
3) Injector size. 350cc is too little to keep duty cycles down and oem fuel pressure.. RDX410 or even 440cc

You've got more to put your money in than to worry about some Throttle Body upgrades. Doesn't do any good if the whole system isn't tuned properly.

 

Thanks for the heads up and recommendations, I understand there are more options with obd1 but what really the difference preference?

 

Camshaft selection depends on what power goals you are in search for as previously stated. I'd listen to shodan, I think he knows his stuff.

 

Okay thanks! And I was aiming for 230 whp? I think it's doable...

 

Hmmmmm I'm thinking along the lines of Pro 2's with this build...especially aiming for 230. Also I would scrap the blox and look into a performer x or if you have the budget king motorsports performer x. Those 2 parts will lead you to your goal easier than anything else.

I would refer to this thread for info. Lots of it is useful although it is a 87mm crank instead of 89mm. It should point you in the right direction. https://honda-tech.com/forums/all-motor-naturally-aspirated-44/230whp-82mm-b18c1-set-up-3010563/

 

Thanks for the advice I was kind of thinking something similar with all the reason I've been doing on the performerX's but won't the s2 p2s be a little much consider my cr will not be the highest or do you think I could sneak by with using these an squeezing a little more power with them?

 

And I was also wondering why a lot of people are going with this compared to the other reputable im's?

 

Very nice You got "a & u" mixed up though j/k

 

The difference is the ability for the ECU to be programed more efficiently and with higher resolution than OBD0. Plus, you will have a hard time finding anyone willing to work with that antiquated EFI system. Go OBD1, to get a better result with what you've invested in.

For 230whp NA on a B-series, you'll need it.

 

Lol I know ive been thinking about it, im sure ill end up switching over to the new age haha. And the kingsmotoraports performerX im are a pretty penny whats makes that intake better? The length of the runners? What if I were to get my im I have now ported the same as they do the performeX's?

 

If you run the P30 B16 pistons your compression will be just fine to run pro 2's.

 

They do a WHOLE lot more than just some runner change. Google the Performer X Kingmotorsports process.

Alright thanks! I was wondering if it would be fine. What's the cr on those again?

 

I did all my measurments using standard 81mm bore, standard deck height and no milling of the head with OEM HG to get my numbers. LS block w/ LS crank, rods and P30 pistons you are looking at roughly 12.1:1 CR. With a PnP head and Px intake Pro 2's wil respond extremely well.

 

Damn thanks, and what about possibly a thinner HG like 2 ply cometic? Or just stick with oem?
