All Motor Miata Tuning and My 1999 ITB Miata Engine - GQM Garage

[@kevinhsu7733]

This is a very very great Build , I adore Allmotor builds doesn't matter what displacement , just get sick and tired of people saying i should go boost to make all the power it needs , maybe i don't want it , maybe i just prefer to be the underdog

[@TheSlipAngle]

Thank you!

[@Consolol]

Mad props to you man. I love it. So glad someone is finally showing what N/A miata engines can do.

[@TheSlipAngle]

+Consolol Thank you ;)

Yeah what they can do hit a top speed of 110 granted they do good drifting they are so underpowered

This is exactly around what I want to do to my NA, right now its got a stock 1.6 in it, the goal is in a year or so to buy a 1.8 and start building it up while still driving the car in its stock form and getting handling and cosmetics all where I want them. Then bolt new motor in when its done! I have never done motor work before though, so I am really just not sure where to start, its a lot more precise work than your standard unbolt old part bolt on new that 99% of what I have done so far is! For now I will keep on researching and learning! Fantastic video, I have watched a few of yours and you have some awesome cars!

[@TheSlipAngle]

+Harrison Davis Thank you. I documented everything I've learned along the way here: clubroadster.net/vb_forum/89-roadster-projects/16110-quinns-nb-thread-itb-content-22.html#post5276673

[@davisharr]

Quinn Kizis Thanks, I have read your thread about your engine on Clubroadster and Miata.net before, big fan of the car, cant wait to learn more about mine, its just hard to find out where to start!

[@paulp7692]

Incidentally, when you shave the head even a little, it changes the distance between the crank and cam gears. This means that you are changing the cam timing, and to correct it you need adjustable cam gears no matter what cams you're using :)

[@realweston]

Super sick video, I really liked that I got to take a look at the pistons and the valves, me being a super novice at engine build this has been an experience. Thank you. Also I love hearing that engine redline, your a mad man!

super clean work.

[@chasesargent5578]

Thx I was going to do the same but awseme thing bout a NA is exhaust is a great way to get rid of crank pressure if still running stock manifold and having a good PCV valve my build I used a pannavac from a old crysler system if you don't have the money it will work great for higher compression builds long live the BP

[@erikborg5891]

those independent throttle bodies 😍

[@spacecassette2108]

I have a BP-4W that i am tearing down and rebuilding wish me luck haha XD interesting build! Thanks for sharing

[@TheSlipAngle]

Thanks man, good luck! 👍

[@grapeknutz]

VERY NICE!!!! Have you thought about doing the coolent flow from the back of the head and eliminating it from the front of the head? As I undestand it will even out the head temps.

[@ZentRose]

Fantastic video. I love the track footage! Braaaaaaaaaap Brraaaaaaaap … your car sounds sick and I want to drive it :) Keep it up!

[@zeroswings2]

could be piston rock at TDC that is causing the mild valve to piston contact... just a thought

[@KurumaDesigns]

That sounds amazing!

[@Floordford]

Absolutely great video. You earned a thumbs up from me.

[@susuys]

And I have just reached similar problem on my VVT head, and 278/278 Cat Cams. At VVT max. advance, valve-to -piston clearance is about 0.8 mm just on the same position as yours. Except, I have not shaved the head yet. I will free up some space by machining side of the valve pockets. Quinn, have you used any template for cutting the same amount of material from pistons?

[@arauzmotoring1741]

Did you end up shaving the crown of the piston?? Looking forward to seeing an update Quinn!

[@TheSlipAngle]

Erick Arauz You'll see :) I am in the process of assembling the engine now and shooting video for it.

[@morpsox]

u should try mounting the fuel injectors outside of the bells facing in. im curious if the better atomization will yield any power gains.

[@TheSlipAngle]

+Scarry Garry I'm sure it would help a little, however I wouldn't be able to run a filter if I were to do such a thing. The injectors are already moved from the stock location on the port of the cylinder head to the middle of the runners in the ITBs to improve atomization.

This is amazing

[@fez455]

Hey Love the videos. love them so much i purchased a miata of my own. You should make an episode on comparing the miata vs. the s2000 and if the price jump is worth it? or can the miata be just as enjoyable with a few mods. would be an interesting with your thoughts on the two cars. Cheers

[@TheSlipAngle]

+Brendan Wilbur Thanks man. I was hoping to finish setting the S2K up before I gave a true comparison. Unless you want to hear about stock vs. stock, or stock S2K vs. modded NB.

[@fez455]

+Quinn Kizis stock vs stock and stock s2k vs modified miata etc. there both at the top of the list of roadsters to buy. But there's a big price gap between the two. it would be cool to have a comparison of the two vehicles and what's similar and different about them and what your general thoughts are on them. since you own both vehicles simultaneously. it would make an interesting episode! cheers

[@TheSlipAngle]

Gotcha. I will try to put something together in the future. Thank you for the input!

[@fez455]

+Quinn Kizis awesome keep up the great episodes

[@jakenuno9900]

Did you ever end up swapping in a K?

[@RamiPapas]

Could you please make a guide of how you got your stock miata to this beast of a car? Really love cars but I don't know nothing about how to fix them, how they work or how to performance modify them

[@TheSlipAngle]

+Ramiro C. I have build threads under the name Quinn on Clubroadster.

[@KawekaJC]

Although I don't have a Miata, I have found this build and your videos to be informative and inspiring - keep it up. How did you create the extra valve relief after the 100 thou head shave?

[@TheSlipAngle]

Thanks man. I ended up just cutting the reliefs a little larger with a dremel to make the clearance I needed.

[@frankgrimes8714]

really cool. Would coil on plug help gain a bit more power? What about a crank wiper?

[@TheSlipAngle]

+Frank Grimes I doubt it with the coil on plug. I am not blowing spark out. As far as the crank wiper, I am not sure how much frictional loss there is at the crank with these motors, so its possible there might be a couple horsepower there.

[@svriderpokey]

Awesome video. Really well done. Have you done a 3 angle valve job, and back cut valves? I've heard that those help enhance just about every other breathing improvement. with the right equipment, and the head stripped of course, its a really easy process. I've done it several times in auto classes, but unfortunately, never to an engine that was meant to run again.

[@TheSlipAngle]

I didn't touch the valves, but I did port the head a little on the latest revision.

[@frankfitzpatrick5300]

Fantastic job with the engine ....Since the shiny spots show interference ....Wouldn't it be on the safe side to utilize a slightly thicker gasket to be on the safe side... Not sure If Hondata makes a thicker one ...But someone has got to make one....I would even look into a reusable copper gasket , they also flatten less & manufacture them in different thicknesses , also the ones ived used over the years have have a great seal & good seals around the tops of the cylinders ....Just my 2 cents ... GREAT VIDEO & ENGINE .... thanks

[@TheSlipAngle]

Adding a thicker head gasket reduces compression. So running a thicker head gasket to shave the head more will yield no change in compression, just a head with less material. I ran this setup without any interference issues with a .060" shave and the stock .020" head gasket. I am considering dremeling down the crown of the relief cut on the piston so I can shave the head another .020"

[@frankfitzpatrick5300]

I did not think of that , what about the piston crowns ...Are they coated ? You definitely know what your doing ...Again , GOOD JOB , GREAT BUILD

[@helloworldinthenet]

Frank Fitzpatrick No, they're not coated. Also look up Jafromobile here on KZbin. he uses 4G63 engines but many of the concepts should still apply, specially with his Hyundai build. He has a head has had too much shaved and shows how he gets more clearance for the valves. Great videos explaining what is to some hard to to understand just by reading.

[@robertdewerff1114]

Great work! Is it possible/pragamatic to grind... or massage more relief in the piston?

[@TheSlipAngle]

You can make the reliefs bigger. I only took as little material as needed to provide enough clearance.

[@sp33der617]

Any thoughts on why you went with the TWM ITBs over the Jenvey units? Nice build btw.

[@TheSlipAngle]

+sp33der617 Mostly because of the price and the fact that Jenvey didn't have a complete kit for the Miata at the time. I bought these back in 2009.

[@NB8393]

Great videos! For the K swap check out "one lap of America" Miata swap. It's the direction is like to go and would love to see your take on it.

[@TheSlipAngle]

+NB8393 Yup I am familiar with K Miata and their kit. I think it's great honestly. If I were to start over I'd take that path in a heartbeat.

[@pigeon853]

give me your best estimate, how much whp would I be looking at with a 2001 miata, 0.040" head shave, RB intake, flat top/vics/vtcs intake manifold, RB header, cat delete, 2.5" catback, and ms3? how much do cams add? how much does ITB add? not planning to rev over 7k. thank you. this video is GOLD

[@TheSlipAngle]

I think you can make somewhere around 145 -155whp. Add 7-10 for ITBS and another 7-16 for cams depending on how aggressive and how much more you up compression to match them.

[@pigeon853]

Are the ITB really worth 7-10 WHP over any intake manifold? I thought I read that the flat top made the same HP as the ITB below 7k?

[@TheSlipAngle]

If you can make the head flow more, then the ITBs will benefit over the flat top. The size of the ITBs matter as well.

[@mrmidnight32]

The idle sounds better than the rev's lol

[@stvkomer]

This is an awesome video man, seriously. Question... what ECU are you using? stock? piggyback? standalone? I am building a N/A BP in a Protege and considering ITBs and a standalone.

[@TheSlipAngle]

+gascanEXPLODE Thanks man. Adaptronics standalone. You need a full standalone to deal with removing the MAF and having aftermarket TPS and IAT sensors when running ITBs.

[@xx4x4x4]

Dude nice vid

[@propertyrights907]

Did you tune the motor using Alpha-N or speed density? Those ITBs can be picky with sensors and such. Also, do you have problems with vacuum pressure? I'm wanting to do this to a 1.8 and I'm stuck at how to tune with ITBs using megasquirt

[@TheSlipAngle]

We tuned straight off of TPS for the simplicity of it and the car actually runs very well. I don't even have a MAP sensor in the car. I run a Golden Eagle vacuum block and have no issues with vacuum.

[@cameronpoces1610]

How much money was hoenslty put into the internal parts and itb

[@finkelsteinyablonsky518]

That engine build is probably close to 11k

[@cameronpoces1610]

also no one makes aftermarket cams for a na Miata not that I could find. but your saying they do for a 1.8?

[@TheSlipAngle]

+cameron poces Maruha does. Tomei makes them for Maruha iirc.

[@Rumoozay]

Quinn Kizis is that the Joyfast Super Short shift knob your using?

[@TheSlipAngle]

Nielex

[@andrewkirby6710]

Call me insane if I am, but would it be a terrible idea to take a Dremel and VERY lightly widen the valve reliefs in the pistons? If its only 2-3 thousands clearance that you need, I would imagine it wouldn't reduce the structural integrity of the piston any significant amount to do that. Just a thought...

[@TheSlipAngle]

I did that in 2014. Check the follow up video ;)

[@ricepony33]

I'd put rods and pistons in it if you're there already, spin it to 8500 and you'll have your 200hp.

[@chrisrucker2819]

I have a 99, and I have been looking for a good streetable set of cams. Any idea of where I can find a set that doesn't cost $800?

[@TheSlipAngle]

Maruha cams are like 250.00 a piece now last time I checked. Their F-Cam lineup is the streetable (like stage 1) lineup.

[@jamesnotyou96]

Hey man, I got a full stock 99 NB that makes a really bad grinding noise if I hold the RPMs at one number after 2500, any idea what this could be? It sounds like it's in the top half of the engine. Just had all of my lifters replaced. Thanks.

[@TheSlipAngle]

+jamesnotyou96 Why did you replace the lifters? If the noise is new and you recently touched stuff, I would re-trace whatever was touched. I've never heard grinding noises from a head, but the cam caps maybe being torqued incorrectly comes to mind. I am not sure what else could make that type of noise from the head.

[@melvinmazda8374]

I'm have questions on headers I'm looking to put new headers in my 02 miata but I can't find any and racing beat is carb legal for racing only, wondering if you know any that can fit or work

[@TheSlipAngle]

Racing Beat are the best bang for buck. If you want beyond that, a Maxim Works will run you close to 1k and a Maruha VP around 1200.00. I am not aware of anything else that has been proven to provide decent gains for the mone.y

IS THERE A PERFORMANCE CHIP YOU CAN BUY ???

[@TheSlipAngle]

I am not sure. Honestly, the proper way to get the best out of your engine is to have something that allows control over fuel and ignition timing, this way you can tune the car optimally and safely for your engine modifications.

i just put together my 2000 nb with the stock head and the block from a 2003 and i cant get it to run right do i have to buy a megasquirt in order for it to run properly

[@TheSlipAngle]

+Thecharliejolly No, the stock ECU should be able to control everything assuming the peripherals and internals are mostly stock.

[@TheSlipAngle]

;)

[@bayrckz]

Im actually doing an all engine 1.6 build right now im budgeted out to about 6483 right now after putting together all the part prices and whatnot. looking at about 150-170 whp. How much did you spend ballpark on this setup?

[@TheSlipAngle]

+bayrckz You'd be lucky to break 150 whp on a fully built 1.6. Do not waste your time and money on the 1.6. The head sucks and just does not flow. It's fine for boost, but all motor power is not happening. A stock 01+ 1.8 can do 150whp with bolt-ons and tune. If you want all motor, then save yourself the hassle and do a 1.8 swap and start there.

[@bayrckz]

thats the point of machining though, I'm not looking for crazy amounts of power, It's almost unecessary to have over 150 to the wheel for tracking honestly. It's all about having that power at a whim and not just spiking at 4-5k rpm. More responsive and alot more reliable than F/I

[@TheSlipAngle]

+bayrckz Building an engine does not equal reliability. Reliable is how the engine leaves the factory. I did 172 whp on a completely untouched bottom end and it never skipped a beat, 152 whp on a completely stock internal BP4W. 150 whp sounds nice on paper but it's really not that fast.

[@19roadster99]

+Quinn Kizis it's better than the stock 90-100hp... Ik the struggle all too well, I'd be blessed to have 150hp in my car.... lmao
