Default Greddy/BEGi-S vs. ITBs

Tried searching Miata.net and Yahoo! for How-To's on running ITBs on our 1.6s, came back with nothing.

What are the pro's and con's of the Greddy/BEGi-S kits versus doing ITBs?

Any links to How-To's on ITBs?...because installs for Greddy kits are all over...

I would prefer to stay NA, but if ITBs are a huge (or more than a kit) headache than I'd rather avoid it.

Discuss.

Well...turbo is spending lots of money...and getting something for it...

and ITBs is spending lots of money and getting...well...a cool sound?

If you want an all motor car, get an LS1, or buy a honda...the miata will never make much power even with a fully built high comp. motor...

But I'm not turbo so I wont preach anymore.

A begi S kit would make more power, be more upgradeable, more reliable, cheaper, etc. Most on this forum don't like ITB's, and will tell you to buy a begi S kit. Fuji Racing sells ITB kits, but not sure if they fit 1.6. If your looking for cheap easy hp, turbo is the way.

if when u get it tuned, (which i heard is the biggest challenge of itbs) then u can get decent results...

fuji racing managed 175hp w/ their itbs, cams, MS on a stock block...



they do look better... if i were going to stare at an engine bay, i'd stare at one w/ itbs

Turbo.
Turbo sounds better too.
Even staring at an engine bay, I'd rather stare at snails.

No they didn't. Don't bring that bullshit to my forum.

You better do more research buddy. Jimmy was quickly proved wrong on that claim.

Depends on what you want to do with your car. There's no doubt a built motor + ITB + standalone can be a quick car. It'll also be more "exotic" than a turbo set up, more expensive to build, louder, blingier, and ultimately not as powerful.

Turbo is the best bang for the buck if you want to go fast. Can be done for less $$ to get the same power. Is quiter and stealthier. Will not have the throttle response. Will have more head room to make power.

Use my setup for an Example. My complete kit with a new clutch cost me about $1300. Most stuff used obviously. For maybe another $600-$800 for Megasquirt and some injectores im ready for well over 200whp with a proper tune. So for about $2000 give a take a couple hundred you could have a very fast car. The kind of power you would never achieve with ITB's.

That's not true. An ITB car can make big power, with the supporting mods in place. I drove one once, and it was pretty fast. And noisy, and buzzy, and loud, and didn't idle, but pulled pretty hard up top, as 200 hp should. Problem is, it cost $10k to do it, and wouldn't pass emissions.

ITBs = I Like To Spend lots of money for minimal gains and throttle responseB.


you're talking spending more on ITBs for 10-15rwhp at most (ITBs + EMS), vs. spending less and getting something like 50rwhp with unlimited upgrade paths.

If you like Torque, Gas Mileage, Horsepower, reliability, drivability, go turbo

If you like "wow thats shiny," and dissapointing people when you tell them how much power you make, go ITB's

ITB = In The Butt, because thats what you get after spending a ton of money for minimal gains.

lol

If you want something drivable outside of a track, you're going to be south of 150whp. The Fuji car didn't make 170whp, and barely runs below 4000rpm. If you search youtube, you can see videos of a turbo miatas shitting on his chest as they shitstomp him all over the track. Do you want to make 140hp, tuned as far as it will go, or run 240whp with a conservative tune, and have more gear to play with, pass inspection, and be able to drive the car on the street?

You are asking that question on a turbo board and I am pretty sure you'll get votes for an itb setup. obviously, i am being facetious.
I've got an itb setup and I do love the throttle response. I tracked the car a weekend or two ago and I was amazed with the throttle response. I was revving the 1.6 all the way to 8000rpm and waiting for it to blowup but it didnt...lol...An itb setup will involve more work and money. I've got my next project going that involves a 99 head mated to an 01 shortblock. I wont be staying with the 1.6 much longer. Money is money and if you have it, youll spend it.
My last band aid to get power is forced induction....i would probably plumb a turbo with my itb setup.

you already get improved throttle response with a turbo, however, not as much as a ITB. You'll receive no benefit from a ITB once a plenum is built and a turbo hooked up. One large TB will suffice.
