motor build

[Doubt it runs]

so i tried to make a post in the motor section.. but apparently i havent reached "stage 2" yet ha.

motor is out of a 95 AWD TSi Talon. it was making very bad noises so i went ahead and pulled it. based on the information so far i am going to do a pretty much stock rebuild, with a MLS headgasket and head studs. new bearings, rings, lifters, water pump, oil pump, timing chain etc. if its lucky ill do a fuel system later and then a bigger turbo.

im doing something a bit diffrent, the car is an auto car. id love to put a stall in it, but im afraid it would kill my resale value to a "normal person" if i do it though. just wanting to see who else has built a bigger turbo, stock stalled motor.

I run a small 16g w/ stock converter

The off boost power is actually better I guess because the air flows more freely through bigger turbo. It spools like a t25.

random question. my motor was making a weird noise. when i removed it i found something weird. should the middle two rods have bearings? when i took appart my motor the front and rear ones have rod bearings, but the middle to dont. is this a problem or can i go ahead and put my motor back together?

dude all those rods should have bearings. check your main bearings as well. Definitely change your bearings and have your machine shop check your crank and rods coz they will probably need some machining before putting those new bearings on there.

question is....where did your bearings go! i worry that the metal pcs. all over your engine!

dont want to frighten you buddy but looks like a serious dilemma you've got there.

There should absolutely be bearings...

And regarding your orignal build, I recommend the OEM composite headgasket with ARPs over MLS. MLS requires extensive machining of both the block and the head sorfaces to ensure a good seal.

if metal is in the motor make sure to clean everything, oil pump, turbo.

that was some sarcasim guys ha. i know it was suppose to have bearings. they were either taken out or never got put in during a build. its stupid. its getting a new oil pump etc. it has a new turbo on it so im worried about it getting hurt from the metal in the oil.

some people have said something about the crank not being able to be turned or something like that. please give me a reasonable explanation.

as for the mls gaskets. they seal better than composite gaskets. im just going to scrape the head and the block clean and itll be good.

Extensive machining??
The MLS will work just as good a long as you have a good surface.I did not have any work done on my block on top.It worked for me.and the MLS will always be better than the stock composite gasket.

You should check to see if you have a ""PERFECTLY FLAT""!!! This would require a straight line ruler, like for snap on. Would cost about $100. And then you would need filler gauges. To see how much your block is warped. I don't recommend putting a MLG on a block that is warped.

Then you happen to be in a the lucky minority. An MLS gasket requires extremely tight tolerances in terms of the two mating surfaces. I've even seen people with machined block/head that have trouble sealing.

MLS is not necessarily better, just different characteristics. For people who are running less than 30PSI, a composite gasket and ARP head studs will do the job nicely.

Yeah sorry we didn't catch on to your humor in type. Is your turbo "getting hurt" humor too or a real question?

And MLS doesn't seal better than composite gaskets under 30psi. The seal is absolute until you run enough boost to compromise the material of the gasket (30PSI+). If you don't plan on running that much boost, using an MLS is just going to cause you unnecessary headaches.

turbo is a real question

why is it that a 4G63 is somehow diffrent than every other motor out there? on EVERY motor EVER a MLS headgasket seals better. thats why they are using them on tons of new motors.

i wish that i was able to post in the motor section, but i have to post whore untill i can.

A MLS isn't beneficial unless you get the head decked, and the block decked. Even then, it will still leak until it hits high boost.

 

[Doubt it runs]

the block is at the machine shop being cleaned and checked. new freeze plugs also.

head is being surfaced and cleaned as well.

then for the sucky part of buying parts and putting it together. as of now im gonna get some clevite bearings, and just stock rings. reuse the girdle bolts and the rod bolts. i already have ARP head studs also. anyone else have any suggestions?
