They were right when they said that its not a bolt on type install. Seemingly everything needs to be modified to make this thing fit. I will have pics later on tomorrow after I completely finish the install. All I have left to do now is shorten my intercooler pipe, and find another ground for the fuel injector/ ignition harness ( it was previously grounded on the intake manifold ).

1. The 1.6L throttle body was not designed to work with the manifold, but by using the FM throttle body spacer you cna make it fit perfectly. If you dont use the spacer the TPS will contact the manifold and not allow the botl holes to line up.

2. There is no spot for a PCV valve, I decided that Im not going to run a PCV anymore, and Im going to make a custom catch can down the road. For the time being I just have the PCV plugged.

3. 1.8L stock fuel rail does not even come close to fitting. You have to bend the metal fuel lines on it and cut off some excess to get it to fit in there. This took me a good while because even after you bend the lines they still want to hit the runners, I think Im just going to get a dual feed rail since it will fit much better and just be better all around.

4. The vacuum lines come off the bottom of the manifold, it sucks because there is precious little room to work with under there and I would have liked to see the vacuum ports come off the back or top of the manifold to make it easier. They also get in the way of your hand when you are trying to tighten the bottom bolts on the manifold.

5. There is no vacuum port for the brake booster line, so I am just going to use one of the 4 ports on the underside of the manifold specifically for the brake booster line. This sucks though because I like to have one vacuum port for everything in my engine bay, but I guess I will make due with some Vacuum T's.

All in all its a difficult but not impossible install. I am hoping to have it completely done later on tonight. I have to modify my intercooler pipe, and find a new place for a ground. It does look really nice in the engine bay, its so much bigger than the stock manifold. The plenum is huge in comparison and the runners are nice and short, perfect for FI. Ill have pictures later on tomorrow hopefully.

Don't use a bunch of T's. I used a manifold from McMaster Carr and barbed fittings screw directly into my manifold. I have my MAP sensor, BOV, and Boost Guage all running from one. I used item #5469K121 @ $13.87 and it is a nice black anodized alouminum unit.

Can't wait to see pics and then the dyno results!

Really curious to see if this improves the torque drop after 5k rpm. Still wondering if it's the intake manifold or cams, or likely a bit of both.

i'm sure begi would be interested in all the feedback. like including a spacer for stock TB, vac port orientation, etc.

can't wait for the pics.

This might be my next mod. I would like it to be more of a PNP install though. I'm interested to hear about your results.

Why don't you just drill and tap to put the ports where you want them and use nice allen head pipe plugs to seal what you don't? Good to see you are doing better financially.

hahah, did he pay you your $100 yet?

He owes me less than that now. Kinda weak that parts are being bought and I am left partially paid for 3 months now.

Im still waiting on my paypal to become active again, Its still got a hold on the account until this guy in australia gets the parts that he bought from me. I can send you a money order, but I would just rather use paypal if I can. I actually told BEGI that I wanted an intake manifold and was put on their list...I didnt know that stephaine would ship it before I even payed for it. I did already pay for it but that was with a CC and not paypal. I can send you a money order if you really want to, but I think paypal should be working shortly.

F20turbo

I dunno, I guess I didnt feel like tapping all new holes when they already had them tapped for me.

F20turbo

yeah, i was going to send all my install notes to stephanie over there at begi.

You may witness your dipstick shoot through your hood

I am going to be watching that

I'm sort of surprised that this manifold didn't include things like a pcv port, brake boost port and a variety of vaccum ports- being that it's Miata-specific and comes from a turbo shop. Is there some kind of "missed" intention behind that?

That happened to me on my 91 racer and I thought the car was on fire when that oil hit the hood. What a mess!

Yah, or also possible the turbo seals will become your PCV system... I had junk freeze in my catchcan, clogging my block/valvecover pcv lines.... instant smokescreen. Unclogged the lines... normal again.

If you aren't going to run the pcv line to the IM... at least run a hose off of it and out of the way somewhere.

F20turbo

What im probably going to do is run a breather filter off the pcv side just like I have on the other side of the valve cover. I havent ever had any issues with blowby so Im hoping I still wont, but we shall see.
