Wanted: Built shortblock opinions?

[daedalus]

I am getting the MAM built block, I *THINK* I might be one of the first to have it running. I will have it in by summer at worst.

i will be selling my short block that i have now very soon. anyone interested? it'd make for a good build... still running strong

I soooo got ya beat. My MAM shorblock is going to final assembly on Monday, and it should be running by january. *crosses fingers* (first)

once again, I said I wasn't too knowleadgable on this, so just going off some knowledgeable members. this is off turfs rebuild thread

Where did you hear that? I have heard tons of spun stock bearing stories hear and over at probetalk, but not a single story of a spun Toga. Please point me to it...

Aren't those Toga bearings for race applications? If they are, then that typically means they were not meant to last very long.

I'm planning to use the stock ones for that reason. I have heard negative things about the lifespan.

I'm planning on replacing them at the end of each season... so about 8,000 miles or less... I'll probably inspect them at the midway point just to be sure... but never know... I've tossed around the idea of using stockers... as I don't think I'm gaining that much with the Toga's... so that's why I'm still wondering a bit at this point.. I need to talk to and defer to the more knowledgeable types of Nick and Beau.

when i was building my cav, the engine people said, use stockers.. look at it this way, they were designed to last 100,000 miles plus. they arent bad.

i think thats true. id stick to stockers.

Daedalus, I got you beat, mine should be finished today (Mine went in with another block from Beau...the firsts, maybe the other is yours?).

Vindication, here's the skinny on the Togas: http://www.importperformanceparts.net/toga/togabearings_ford.html
I have them and got them coated as well. They are made the same way as the Clevite bearings, so hopefully they will last as well as those. I might be the first to actually use them in our car, I don't think the stock bearings are very good. From an engineering standpoint they are the simplest/cheapest pos designed for a 100hp engine. There are lots of spun bearing stories in the Mazda and Ford forums from NA cars that I felt it was worth a shot to pay a little more and give it a try...

Why yes it is.

What compression are you running? Happy with your shortblock? Look sexy? Eh? I'm just friggin excited to see what this bad boy can actually do.

 

[ddogg777]

I'm running 8:1 compression. I will try and stop by the shop to take some pictures this afternoon...

 

[daedalus]

Good.. That is the spec for mine as well. I'm concerned with the loss of power out of boost as well as how much the boost much be raised to compinsate for the power loss compared to the stock 9:1

Thanks for your help.

Not interested in who get's theirs done the fastest, but who runs the fastest...

If the Buffalo Bills beat all odds and win the super bowl, then I will be getting a lot of money and will buy one of these sooner than summer

 

[ddogg777]

I'm concerned with the loss of power out of boost as well as how much the boost much be raised to compinsate for the power loss compared to the stock 9:1

I was too, but that's why I compensated with the following:
10# Indigospeed flywheel (free up some power)
techline coated pistons/bearings (keep that heat in there!)
AEM engine management (tune that power!)
AEM C2DI ignition with 4 MSD Blaster coils (burn baby!)

I got it at a good cost. What machining needs to be done? It is a complete short-block that has never been in a car. Unless you come up with something I hadn't thought of (which is very possible), all efforts will be in headwork and such.

ddogg777- how much did the techline coating cost? That coats the skirts to make them slide and the tops to dissapate heat correct?

 

[ddogg777]

Correct, it was $100 for the works on the pistons (dome, skirt, underside, wrist pin).
Concerning the block, even new blocks can benefit from the tighter tolerances of a line bore hone and a tighter balancing from an experienced machinist. Heck, even my stock crank needed adjustment to come in even. Also, the main thrust bearing caps are machined and strengthend to accept another thrust tang to keep the crankwalk to a minimum. Lastly, all oil lines and galleys are chamfered and the block is deburred to help oil move more freely. All these little things become huge when the block is pushed to 200hp/liter.

Any chance someone might be able to further explain the once a year replacement of the toga bearings. I know that its been said that they are more of a race type of bearing, so shouldn't that mean that they would take more stress for a longer time than the stockers. I have to make sure that this is a bulletproof block, cause I don't have the money to have to have the block tore apart once a year.

 

[ddogg777]

Well, they have a warranty for 3yrs/36000 miles and are meant to live longer than stock, just follow me link I post earlier...
Stock bearings don't come with a warranty.

 

[vindication]

well, as long as they have a warranty than that is cool enough for me. Not bad changing it every 36000 instead of every 10000. Unless they go at like 36500, that would suck. lol

 

[ddogg777]

35998....35999...Boom! (lol)

Where did everybody get the idea that 2.0's have crankwalk? I have never seen any evidence of crank walk, even from my own blown motor, and that was beaten beyond belief. I think you guys are thinking we own dsm engines or something. Show me proof of crankwalking.

 

[daedalus]

Beau experienced crankwalk due to the weak thrust bearing on their 400+hp engine. It doesnt become an apparent problem until you hit high hp humbers, but it remains a problem nonetheless...

 

[BlkZoomZoom]

Proof?

Is this a secret motor that they never tell the general public about? You would think they would show pics or something to give you an idea of what it did. Maybe I missed the thread.

 

[vindication]

wait for ddogg777 to come back on. He posted it somewhere else I'll try and find it but if I cant then just wait for him to post it again.

 

[vindication]

this is from another thread. probably on Beau's high hp engine

Actually if I recall correctly, Beau had his block magnafluxed and there were cracks about the thrust bearing main cap...signs of crankwalk.
