2860rs turbo

The gauges do look incredible.

So why exactly is the spacer plate necessary? I was just taking a look at it and it seems like I can just remove it and reinstall the 1.6 throttle body. It doesn't seem like clearance will be a huge issue by just removing the spacer itself.

MY solution in my head is taking the rubber washer off the top of the radiator mounts. That will allow me to move the top of the radiator forward 1/2". Then trim another 1/2" off the silicone elbow. That should give me plenty of room without buying a new throttle body(for now at least, I do want to get rid of it.)

Is there a very sound reason as to the thick *** rubber spacer on the upper radiator mount? I don't even have one on my Jetta radiator mount. Doesn't seem necessary if you torque the bolts down correctly.

I believe the spacer is a kludge so you can use the 1.6 TB and thus the giant ugly idle air valve etc with your stock harness, connectors and ECU in your 1.6 car. on't get me wrong, its a beautifully made kludge and works well for the above application, but its not something you need when running a Megasquirt.

You may need to do a little electrical work in the MS to accommodate, but the NB TB with the stock VTPS really is the way to go in this case.

Now to track one down....

Anyone selling one?(I'm looking at you parts supplier Vlad!)

So because of the new position of the turbo I had to make some pretty major changes to the IWG bracket so that they would line up again. After drilling and sanding and bending I have gotten it pretty close to perfect. Just need to widen the waste gate rod role a little so it doesn't rub.





Also test fitted the turbo shield and need to make a couple modifications to make it work.

Need to trim some off the front of it so the waste gate rod doesn't rub.



And I think I need to cut this bracket off due to the brake bias adjuster being in the way of the bracket it normally bolts to. Either cut it or bend it backwards 180 degrees to attach to the brake bias bolt you see in the bottom of the picture.




I also removed the flyin' miata spacer and put the throttle body back on just to see how much clearance I would have...yup, it is the working answer. Not only does it pull it completely off the radiator hose but it also pulls the intercooler hose off the front sway bar even more so it will rub less.

I could trim more off, but as other have said, might as well get rid of the root problem while I am at it.

I told you to message me if you wanted a heat shield made!

Jeffbucc

I totally forgot! My brain is all over the place these days.

Yezzir

Haha, oh well. Shows that you are human after all.

Fitted the turbo heat shield . Took a little grinding and cutting to get it to fit but luckily I didn't have to do too much to get it to fit. Also finished the waste gate bracket so the rod isn't rubbing against anything.

I remove some of the lip up front so that the oil feed line wouldn't rub against it.



Bent the middle bracket a lot to allow it to bolt to the brake bias ****. Turned out great though.



Also got my lower radiator hose from Vlad, and with a little trimming it fit with 1/2" of clearance off the intercooler hose.



Then I decided to make a new air filter box to help lower the intake temps. I didn't have any aluminum so I cut some ABS plastic and used the old box as a template. The reason I didn't use the old box was that the hole for the air filter was unnecessarily huge.

old box



New box with aluminum tape to help reflect the heat a little more. I'll find something that is more one piece to clean it up a little later.



Perfect fitment



Rough fitment, still waiting on the brackets I epoxied onto the plastic to cure fully before I bolt it down. I just need to buy a couple inches of 3" metal tubing to slip onto the 90 degree elbow.

This is looking great man. Killer Scooby band-aid too

Well, except the engine/filter moves, and the heat shield doesn't.

Good call Curly. I recall a number of people have cut through their filter neck because they did not take drivetrain movement into consideration.

Jeffbucc

Good call, agreed. Didn't consider that. Think 1/2" more space would give it enough room to flex?

Yes. 1/4" on each side is more than enough. what I'd do is carefully notch and CURL the sheet metal around the hole instead of cutting it off. It will be much much less prone to cut that way

Widen it 1/2" and maybe put some sort of rubber trim(hose with a cut down the side works well) around the circumference of the hole so there is no sharp edge.

If you don't want to go that route - Do what I did - take a piece of silicone or rubber vacuum hose and cut down one side then place it over the sharp edge of the material you just cut. This will make sure that even with the movement you aren't likely to do damage.

Bryan do you have a build thread anywhere on your Miata? All the little engine bay shots and other assorted pictures I've seen make it look incredibly nice.

Everytime I see a super clean white Miata I have second thoughts about LSB. It just looks so good when it is done right.

Also thank goodness for nice exhaust shops! They just gave me 8" of 3" pipe for free.

Gracias.

I also picked up a 99 throttle body off a guy in Arizona for dirt cheap, so I should get that in the next week. Now I need to look up what wiring changes are necessary to make it work.
