Peppy's Build Thread

Not so much, exhaust can be semi polished as its looking for flow and then reverb pulses

Thanks Jet, much appreciated, you just saved me some time of R&D, I only know the basics of engine airflow but my dad was a well respected cylinder head reconditioner, engine builder and done cylinder head porting with data to back him up for 15 years, (he calls himself an airflow specialist hahaa), and it just so happens that I have a Superflow 110 sitting in the garage, so there will be no guess work =)... We will make everything work together (hopefully)

Any girdle? Atomic? Dynomite?

I would make sure attention is given to the cylinder head sealing side of things so that you can push the power later on.

Eg,

-would the Permaseal MLS do a better job than the Ford Factory MLS: Maybe

-Would putting a sealer like Threebond 1211 on both sides of the head gasket help and is it worthwhile (hard to do right): I think its worthwhile esp on the Ford Factory MLS gasket. Steel on steel does not really seal up well on the water passages.

- If you are going to touch the Factory finish of the Ford deck and head, will the machinist be able to replicate the required RA finish. The smoother the better.

- I personally think 12mm studs torqued up 120ft/lb and even more is fine but something to consider also.

Id suggest using a genuine head gasket vs a MLS

Any girdle will do

Sounds like u have it all sorted on the porting side of things

I was actually thinking of getting the head and or block "O" ringed, is that still something that is done these days?

[rednose]

Some still do em, they make a heap of power though,

My Tuner also prefers using genuine head gasket.

I've done the copper and O' ring. It will hold good but you just got to be attention to detail and there is a bit involved. And at the end of the day a MLS done right will be easier and hold the power you are doing if all done right. I think alot of high power setups are still using a MLS in some form or another.

With Copper my recomendation is to never overlap the wire. Also when installing the wire it takes ages to file the wire to make sure it abuts very tightly. Near enough is not good enough. Then the machinist needs to machine the groves for the correct stickout from the deck. I use about 7thou. Then the most critical part is you need to use Threebond or some sealer regardless and you got to make sure you have enough to sealer but not too much to squeeze out everywhere.

I did do a Ford MLS on a turbo ED with Threebond on a drift car and it gets a thrashing and I think very good.

So that's what I would stick with. I was even thinking of adding two more layers in the existing Ford MLS by using two gaskets to make one and spraying everything with Hylomar at one time. I don't think the stock Ford gasket has much give.

Appreciate the info guys, it will go a long way.. I'm almost at my budget goal so things should start moving soon, I'm sure other questions will pop up so keep an eye on this thread haha,

Thanks, Joe

Slowly pulling my engine apart, and noticed a couple of little things,

-timing chain guide was cracked at the top

-timing chain came in contact with the bottom guide at some stage,

-timing chain came in contact with the recess around the crank gear

The timing marks all lined up and there was plenty of tension on the chain prior to removal, engine has done about 135000km and has worked hard for at least 35000km

Tapatalk isn't letting me upload the pictures, but there not major marks, just curious as to what the cause could be? Snapping the throttle on and off?

For those of you who have retrofitted an fg intake onto a b series, the TB is different, I havn't had a good look yet, but it looks like the bolt pattern may be slightly different, and the throttle controller and TPS are in the same switch rather then separate like the b series.. So is it better to fit the bf TB to the manifold or retrofit the bf wiring into the fg TB? Are they the same resistance? Voltages? The last thing I want is troubles with the Fly by wire

Thanks Joe

[JETURBO]

Keep the BF TB

Atomic sell an adaptor plate for the BF TB to FG pattern
