101MM Stroke 7MGE

[DEFIANT 7M]

OH SHIT:biglaugh: A little modification needed for the modification!!! Wonder if the gasket could fill that gap? Maybe two!!:biglaugh:

Going with stock rods. Putting in the ARP goodies and checking bolt(stud) stretch.

Picking the final six. Only the lightest ones can play...

:biglaugh:Can't reply to bump my old thread from the SM basement. So I'll try go from here. I bought wheels and tires for it today, so it official she runs this year! Still a lot of work left but it just putting back together now:icon_bigg It has been SEVEN years!! The engine has room for improvement, that's how I'm looking at it. Any other way it will never be finished. Shit...101mm stroke, 15:3 compression, dry sumped, ITBs, cams(small), extensive head work, 4.56 ring gear and more. Many countless hours testing, making, trashing and wondering why the hell did you do this!! An internet war with someone who has long since moved on!!:nono: The MONEY:cryh the MONEY:cry: Stay tuned the end is near!!:biglaugh:

Bought wheels and tires today. Wheels: DrifZs 506GMs front 18x8.5, rear 20x10, tires are Nitto Invos. The madness continues:biglaugh:

Just curious, but have you considered running a dry deck?

 

[DEFIANT 7M]

Well, I just read this whole thread again. Wow. I am, quite thoroughly, impressed. Glad to see you back on top now, and that you're close to done. Apparently, very close

By the way, would be interested in more detail about how using the old head for a bore plate worked out...

Using an old head for a bore plate worked great. I did not finish it Darryl did @ RPM. That was somewhat of a major deal, looking back making one from a solid piece of material would be easier.

Welcome back, I think I speak for all of us when I say... I can't wait to see the end result.

I need some NA inspiration!

Hey thanks man..When I started this there wasn't even a N/A section :biglaugh: Now look at us:icon_bigg

Just curious, but have you considered running a dry deck?

Funny...you are the first person to ask me! We started to do it but decided to "rock" the block instead. There is only a 2" deep water jacket now. The hottest part of the engine is the first 2" of cylinder bore during a combustion cycle. So by blocking or "rocking" the rest of the jacket. Not only does the cooling systems capacity and ability to cool the engine increase dramatically. The lower cylinder walls are strengthened "no flex", deflection what have you. Really good in my application since my piston speed will be....WOW! To say the least.:biglaugh:

Where's the videos??? I've been dying to see this engine rev for some time now. Congrats on getting it running though.

Just a few more things before we turn the key. One major deal!! I sold the Holley 950, now I looking for something too run this thing. Looking @ the new Megasquirt II. Any ideas, be easy the money tree got FEW twigs with green on it! Hell I want to make the first crank and run my ringtone!

I read all 38 pages and I can't wait to see the final or even updated product. This is one of two builds I'll be watching like a hawk.

Hey thanks, it's been a long time. I have a hard time driving other Supras since mine has been down.

i think the only way this build could be anybetter is if you went alcohaul instead of gas!:evil2: but man props for doing this this thing will be well sick:aigo: and thats even an understatment.

:biglaugh: I am going alcohol...later! It is one of those rooms of improvement:naughty:

The bottom end was a challenge. We clearance what we thought was enough to find out it wasn't. The crank scrapper and girdle combo need a little modn' to get it to work. We used 7M head studs for main studs because the girdle is really thick! The wrist pins where cut wrong so we had to send them back and get them recut (two years later!!:biglaugh The dry sump pan would not fit with the girdle! This is just the bottom end....My head is just as crazy, with 2JZ shim/buckets, and 2JZ valves. Here are some old pics of the clearancing of the block that was not enough for the stroke!

This has to be my favorite pic! What does a stock piston/rod with a 101mm stroke look like @ TDC?:biglaugh:

 

[DEFIANT 7M]

Can't wait to see this up. I want to see the potential of our GE motors and I want to see which modifications you have done give the most gains without breaking the bank completely.

The blue print is set..it's easy now. We got cams now, cranks, pistons and a way to improve oil flow without a dry sump! Really big the MAF! I could do a few more things but why?

 

[DEFIANT 7M]

Hey Allan, would you like me to clean this thread up so it's easier to view for others?

BTW, you have a PM

That would be great:icon_bigg Then I can see what is missing...Kool

 

[Ma70.Ent]

Ok, done. I just cleaned out a shitload of posts (over 100 easily )

I deleted all posts that had something along the lines of "i want pics" "good work" and "keep it up". I tried to keep the questions so that people wondering about this good read them and have them answered.

 

[DEFIANT 7M]

Allan: Ever thought of getting a shorter timing belt and get rid of it altogether?

I did this with a 2 litre Astron I built for the balance shafts just had to plug the oil holes.
(Looks brilliant so far can't wait to hear it run)

IJ, we are doing this. We are using a freeze plug to close of the hole. Thanks...:icon_bigg

Thanks man this is great:icon_bigg

So did you weld up the head and shape it? Or still trying to work with the stock ports and chambers? Looks like someone took a spoon to the bottom end. Don't mean to be a "asking for pics guy" but I want to see the head and pistons too

 

[DEFIANT 7M]

I've done a lot of things with this engine I really didn't understand, until sometime later. This is one of those things.
We machined the shim bucket (some call them lifters) bores to accept the 2000 and up Toyota Echo shimless bucket. Why??? The cams have such a radical lift they will "spit" the shims out. Or knock them right off the top of the buckets. Machined the bores? The stock 7M buckets are 28mm in diameter, the Echo buckets are 32mm. The cost is about $12.00 per bucket and they come in a range of sizes too match cam lash. I got lucky and had a 2JZ N/A given to me that thru a rod. We stripped the engine and Daryle walks over to my 7M head and says look these buckets fit! Well that was money saved to say the least. At the time the main concern was stoping the "shim spit" problem. Daryle said there was another plus to this mod. It follows the mod many BB Chevy guys do. By enlarging the lifter bore size using BB Chrysler lifters in BB Chevys. The larger bore will change the ramp rates, overall cam duration, and maximum lift numbers. Which will change the dynamics of my cams...too the good I was wondering why he had me get the cams I did, know I understand. I will pick up more duration @ say .020 vs a cam of a similar spec @ .050. Not to mention the increase in lift. I guess you can say the cams will have more leverage to open the valves quicker and a bit longer. Here are a few pics of the Echo buckets.

My villagephotos account has been gone a long time ago. Here are the pics. The first pic is the Echo bucket, which would be a low cost weight reduction in the valvetrain for a 2J.

The pistons are on page three. I don't have good pics of the head, this is on purpose. Daryle spent over 50hrs porting and flowing each cylinder. The flow numbers are +-2cfm of each other.

The crank:icon_bigg

 

[DEFIANT 7M]

Here is my front tire:naughty:

 

[MrWOT]

2618 eh, probably a good idea for that kind of compression. I am a little surprised at a few things, who designed them? I'd really like to take a look at the ports and a better look at the throat area but I understand why, looks like the valve guides were ground all the way to the port roof? Can't wait to see it run

 

[madsupra88]

why didnt you go with a big lift cam? last time i checked ur were trying to get a cam in the .500 lift...
