I need help to finish my long build.

[Aproductions]

I need a timing kit, headgasket and evo 9 specs for the evo springs and retainers installed in a 2g.

I posted this to maybe get some help with these 3.

timing kit- 2 oem pulleys and tensioner and a gates belt.

headgasket- waiting on machine work to figure out what thickness ( I have 9:1 pistons so if I wanted to lower the comp a little, what thickness would be safe)? I don't wanna go too thick.

specs for evo 9 springs and retainers- I found this but can't verify it. basically what numbers do I give the machinist?

this is what I found


"
Some general data used in the test to "standardize" the results a bit.

Installed height general numbers (1.560) for comparison; this includes the mitsu locator given at an average value of 40.

.410 will be used for cam lift.

As follows;

DSM

Coil Bind
1.115
60
1.175 SAFE

1.560 = 68lbs
.030
1.530 = 72lbs
.410 LIFT
1.120 = 192lbs

But we're under where we need to be. When performing this last squeeze there was no daylight left. ABORT ABORT! DSM spring is KO'd. Even if we pull the shim its still over.


EVO

Coil Bind
1.035
60
1.095 SAFE

Installed height general numbers (1.560) for comparison; this includes the mitsu locator given at an average value of 40.

1.560 = 65lbs
.030 shim
1.530 = 72lbs
.410 will be used to simulate cam lift
1.120 = 154lbs

In referance to our original coil bind number, we can see we still have room on the Evo spring. Showing the benefits of the semi-beehive springs and its much looser coils. It would take a 60 thou shim to max this scenario out.


weight

DSM
Spring: 56.3g
Retainer: 13.7g

Evo
Spring: 39g
Retainer: 3.9g "



so any help would be very helpful.

My suggestion:

Use a normal headgasket. You will love the response and spool time with higher compression, and its very streetable with pump gas if you have a good tune.

I dont see why you need specs on the springs. They should work fine. Beehive design are great, just keep the rpm's safe . I mean the shop could check and double check spring height, installed height, and all the movement of the valves in ralation, but its just for a safety measure.

Hopefully I usderstood what you were going for

And what help were you wanting with the timing kit? OEM is great, and gates belts are decent, although I prefer mitsu ones

spring height, installed height, and all the movement of the valves in ralation, but its just for a safety measure.

how to they find out that stuff.

like when you buy say aftermarket springs and retainers, don't the companies give you numbers for install height and stuff?
