I pulled out an intake/exhaust valve from a 4g69 Mivec head.
After measurements and checking Supertech info this is what i found.

Without a valve guide change, we can use valves from the 420a.
If you use 4g63 valves, you will have to change the valve guides.

overall lengths dont match exactly but are close. lash adjusters may have to move from -2mm to +4mm.

hope this info helps

 

custom made +1mm 4g69 valves can now be ordered.
ss, black nitrided, swirl polished, undercut, with flat heads.
it takes 3 weeks to produce.

let me know if you are interested

 

I will be interested once I begin my turbo build when I get out of tech school. I wanna talk to rock and see what all ideas we can come up with for building a good street/strip car. Keep me posted on if they are available or not

 

I know I have a guy whose going to be doing my hole valve train, when the time comes to do my head. but im just curious how much each of these valves cost? I will most likely order two sets. but how much was yours?

 

This is very interesting. I have been tempted to build a car other than my Ralliart as I get the money because of the lack of parts available for it but it seems like new discoveries are being made all the time. Might just keep the Ralliart to mess with after all.

 

yea theres alot of parts that click together for the ralliart. 3-4 years ago the aftermarket only consisted of RRM, but now ppl are coming out with new things, and ppl are figureing out certain eclipse and evo parts fit our motor, so that makes tuning it that much easier and better.

 

Yeah. I sort of think it would be more fun to mess with trying things like the valves than to just buy something and put it on anyways really. I have a friend with a really modified EVO and we are gonna work together this summer on trying to use his turbo and making some intercooler pipes and buying a couple things to get his stock turbo and intercooler on my Ralliart. Assuming all goes well I will start trying to build the motor to take more boost then probably.

 

^^i am basically doin the same thing im just at a stand still i have all the parts i need except for a couple gauges and most importantly the 2000 dollar stand alone

but if you got any questions on parts let me know i should have the answer or at least can point you the right way

 

ok whats up with these valves? i think i'm going to do it in the very near future. it says 3 weeks to order. how much do they cost? i have a guy here who can custom make them, but if your cheaper i'll go w/ your guy.... how much for a complete set?

 

bump

 

pm sent on 4g site

 

did you ever install this? work well or what? and what company made them? I know manley can make valves for our car for about 300-350 dollars. what company made yours?

 

bump bump. i think i'm ordering these valves TODAY so i would like to get info on your valves before i jump into these. I'll also send a message on club4g.org hopefully i can get ahold of you. thanks

 

ok, i just got ahold of you on club4g.org. Guys just to let you know, toortool has some badass valves for sale. anybody doing there valve train or boosting there motors should look into this.

 

Yeah there nice and +1mm , but about the rest of the valvetrain ?? Springs, retainers ,bearings etc. Do you have any info on sizes or swaps from your shop that's building your head LSD ?? Is it done ?
