How to SEE your piston to valve clearance

This is a simple comparison between the stock cams and the aftermarket ones so we could get a visible piston to valve clearance rather than relying on plasticine. PLEASE NOTE: This is not how to dial cams in or get any specific measurements to setting up cam timing. You NEED a dial indicator for that!

[@Theeclipseeee]

This is the best engine phase content I've seen in my life. I was planning to do a similar job, but with the help of plasticine attached to the piston. Could you cut the block in the area of ​​the oil channel to study the option of installing oil injectors, for example, from 4ag 20v.

[@MattBerrymotorsport]

Man thats a cool idea. Im sure I could get a new cutting disc and give it go haha

That's awesome to actually see the valve events instead of trying to visualise them when messing with cam timing.

[@MattBerrymotorsport]

Yeah it wasn't quite the same as i had pictured either lol

[@madfortar2008]

How good are you mate ! Answer too good, Love it

[@timtrial3971]

The way I like to imagine valve to piston clearance is: on the exhaust stroke the piston chases the exhaust valve closed. On the intake stroke the inlet valve chases the piston down the bore. Your risky areas are 10o btdc and 10o atdc

[@mishasingh9774]

Very nice demonstration very informative thanks

[@Ricerguy]

Awesome Video. I used putty... A whole brick and the cams barely sniffed it. 🤣 Messy to clean up. Now you make me want to try that intake. Cam mod 🤣. With my 5efhe cams I switched to using the 4e cam sprocket timing mark, which retards the valve timing slightly(about 2.2 degrees) which smoothed out my power delivery which used to feel punchy and flat, but I've made other improvements since then so this timing mark may only be a myth at this point. Thanks for the insight(literally) 😁👌🏾

[@MattBerrymotorsport]

Awesome man ive been doing a little bit of research and apparent retarding the exhaust cam will give higher hp, but a low end power loss. Doesn't say much about the intake cam though. Ill have to try it on dyno and let you know

[@carlonatividad9304]

Nice one again mate. Very informative video. Hats off to you.

[@carlonatividad9304]

Also can you make a video on the difference between 5e and 4e cam timing marks. Thanks.

[@shayenmohammed2312]

Keep up the great work. Very informative videos Matt. 💯👍🏽👏🏼

[@DjeDrie]

Thanks for not clickbaiting us man :)

[@christiancianflone1740]

to anticipate the intake cam by two teeth is the engine torque lost a lot?

[@vikrammalviya7917]

Amazing 👍👍👍

[@nikorosales-rios146]

Hey Matt. At first, thx for this very interesting Vid! At 11:34 you mention that is some „xxxxx“ camshafts are needed??? 🤔 So, it‘s NOT possible to do this mod with stock cams I guess...

[@MattBerrymotorsport]

Yeah you need to buy cams with a larger lift and duration.

[@nikorosales-rios146]

@@MattBerrymotorsport thx a lot! So again: is it posible to do this mod with stock cams or is it not recomended??? And, if I put some larger cams in: is it really necessary to do the mod??? Pls, clarify! 🥴

Yes it is

I have a 5e fe engine that lick bearing would i notice any power differrence if intall a 4e fe block

[@dunkthebomb]

Hey mate very interested in your custom itbs using factory tb do you have any more info? Seems cost effective if proven reliable, Was reliability an issue is that why you changed back to stock plenum?

[@jnprivera1542]

I wish you understand how hard it's to get 5efe part in USA and you just cut that block🤯

[@MattBerrymotorsport]

It already had a hole in it lol Also for how rare and over priced 5e are nowadays, you may as well get a 4efe for $100 and put a set of forgies in there... The extra 200cc in 5e hardly makes a difference

[@kingbeloy]

You blown my mmind every single video its not safe 4 my ep91 glanza turbo and ep82 na :D

[@findtherightbeat]

How is it running? That's a very big dome, how's the flame propagation?

[@MattBerrymotorsport]

Hey there its on a halt for now, I couldn't find the block and rods I needed to go with the pistons. Ive had a few people mention flame propagation but im not sure how the higher dome affects this? I'm still learning about this, so any explanation to that is much appreciated. Thanks for the comment

[@findtherightbeat]

@@MattBerrymotorsport I had a .pdf of a study Mitsubishi made some time ago on this, but I'm not sure which external drive I have it on, wish I can find it. Some builders/tuners I followed have noticed and have advocated just using a mild dome or the combination of flat pistons and milling the head slightly to bump compression to make power but still have resistance to detonation and can pull under high load, they say it just requires tuning out the part throttle pingies

[@Runaeh]

nice research, what valve springs, retainers did you use on 5efe ? i cant seem to find a decently cheap retainer option. a good cheap for valve springs option is 4afe ones for na builds

[@MattBerrymotorsport]

Stock retainers. Springs are from a company called performance springs. They cost me around $240

[@MattBerrymotorsport]

In my other turbo 5efe, I also have the same springs and factory retainers going to 8500 rpm with no problems

[@leongustavson8746]

Would advancing intake by just one tooth be worth accessing on a dyno Matt? Also is the exhaust cam opening further than intake in terms of lift?

[@MattBerrymotorsport]

You will gain a little down low, but top end will heavily suffer

[@leongustavson8746]

Matt, a toyota supercharger off a 1g-gte would be interesting on 4e-fe.

[@MattBerrymotorsport]

@@leongustavson8746 hell yeah it would :)

[@grilloperformance2982]

wondering if advancing intake cam will work for boost application.

[@MattBerrymotorsport]

I am yet to find out. But I am sure you do not want any valve overlap with boosted applications.

[@MattBerrymotorsport]

Try advancing the cam though, atleast we know the valves won't hit! :)

[@Wolf-zb9qs]

at what lift did you measure opening from ? 1mm ?

[@MattBerrymotorsport]

I measured it by eye lol I'd need a dial gauge to measure it at a specific lift. This test was just so we could see visual valve clearance and not for exact numbers.

[@MaDcOw1986]

You should have chopped a portion of the head as well for a better view..

[@luistorreslopez2761]

💪🏽💪🏽💪🏽

[@rje1407]

Can you also advance intake cams on 4efte engine? Or is it only good on 4efe? Nice vids btw

[@MattBerrymotorsport]

You can but the problem is once you get valve overlap (when the inake and exhaust valves are open at the same time) in a turbo application it doesn't work well. You end up with higher exhaust temps from the wasted unburned fuel going out the exhaust and the engine runs less efficient. If you just move the cam belt pulley instead, this can advance or retard BOTH cams evenly. Problem is when you advance both camshafts you get better low end power but top end suffers. When you retard both camshafts you will lose low end torque but gain some in the top end. But where Toyota have set them gives you the best of both choices. If you have a fairly small turbo id just leave the cams where they are :)

@@MattBerrymotorsport my car is build for drag racing here's my mods in the engine -stock internals -ct12a turbo (the big one) -front mount intercooler -ramhorn turbo manifold -aem fic -350lp fuel pump What do you advice on my build? Do i retard the belt or advance it? And by how much

[@MattBerrymotorsport]

@@rje1407 that's already quite a small turbo. Will be pretty zippy but the rear housing won't flow enough in the top end meaning you won't get very high mph at the track, maybe around 90-100 over the finish line and maybe a low 14 second pass. Advancing the cams will make that mph even slower but it will probably improve the time a little bit. I'd be looking for a larger turbo like a tdo4. One of my other starlets ran a 13.0 at 105 mph using a stock engine and similar mods to yours. I also had 15x8 drag slicks which helped a lot. This was on with the stock cam timing. If you don't want to change turbo i highly recommend spending the money on a set of drag slicks and converting to e85. This will help a lot :)

[@rje1407]

i think this turbo is different from what your thinking some of the people i have ask is that the turbo came from 1jz and its a little bigger than the td04. If you have face book or insta i could dm you some photos btw iam from Philippines

[@rje1407]

Slicks is really expensive here in my country and e85 is not available here but we have a petron blaze 100 octane will the fuel do the work?

[@loudmikemedia]

Oh is that how u do it
