So OD torque blows gaskets and what else. I was thinking I'd get some head studs and an ams rebuild kit. How much further should I go for that much torque?

 

Rod bolts seem to be the weakest part of the engine. The rods themselves are also pretty taxed at that level. There are people that get away with 600whp on the stock block though, so you never know. I have been around 500-540whp for the last 3 years now and haven't had issues yet. My torque has been 400-420. You are going to be hard pressed to make over 500whp on straight 92 octane with a stock block. I run E85 at 32psi to get this much power.

 

ive been fine for almost 2 years.

 

what are your power goals and do you wanna stay stock frame or go t3/t4?

 

375-400 whp with the E9 turbo in an E7 on 98 RON gasoline. I have so far K&N tube intake, 3" TBE, AEM wideband for tuning,Autometer boost gauge. Looking at cams, any recommendations.Wanna keep it DD also!

 

Detonation (knock) causes heads to lift

 

With the other mods you plan on doing I'd say bbk-b or MAP EF 3 for those goals on 92. Yes you will need larger injectors ad ad a dw 300 or wal. 255 fuel pump.
If you atre dead set on using meth don't go cheap get a good kit with a good fail safe option. Where lots of people get into trouble with meth is they don't have enough injector and the meth becomes a band aid fix. So be sure you have enough fuel before adding meth. As stated try to keep it around 400 TQ atw.

 

468tq. Did a ton of damage; hole through the radiator, t-case cracked open, 9 holes in the oil pan, head needed new everything. I have seen a good amount of 05's throw a rod like mine, I was only going 35mph and barely on the gas when it blew.

 

Wow if ur gonna do it then do it big i guess lol. How did the t case crack? It shot parts through the radiator?

 

i wouldnt do anything over 400 for a long period of time

 

My car made 515/416 on a mustang dyno on the stock block with a FP 3586 and was fine for two years. It seems like everyone that doesn't care if they stay together they last and those that want to keep it together they blow up lol. I tried a lot to get mine to shoot a rod and it never did

 

Once you get to the 400-450 wtq it seems to be WHERE the tq hits, not how much. I think anything over 450 and you're asking for it!

 

Definitely a helpful thread

 

late tq is what the 4G63 likes that's why almost everyone here with a red, black, ef4, 6262, 35r etc keeps there block I have a FP Red DBB with 134xxx miles on the block and my tuner kept the tq under 380 with a 3 port and made 487awhp and had no issues, now decided to build the engine because the cyl#3 was low on compression and the large amount of miles, and almost every Friday I took my car to the track I ran the sh&t out of that car but never had a problem with the Red I was running 28psi and after 6k or so 32~33psi and had no issues what so ever. So it really depends on your tuner and turbo definitively if I had to choose again I'll go with a black or 6262

 

Had an old FP green but didn't like how punchy it was when it spooled... Just did a MAP EF3 tuned at 501whp and 376wtq which seems to be fairly conservative. It's my daily and I love it.
