Beefing up the short block for tt

BlkNismo · 01-07-2013, 09:51 AM

I have plans for GTM stage 2 TT. I would like to beef up the short block in hopes to have a very reliable car around 525whp. I understand reliable is subjective and heavily relies on components used, quality install, tune, and your right foot. As many may suggest, I will be fine on oem internals, but for how long? Car is a dd, I would like to do it right the first time.

In for opinions/thoughts on build components or any other thoughts or input you may have.

Pistons- looking into Wiseco, what are thoughts on either 10:1 or 9:1 compression.

Rods- Eagle or K1, which brand has a stronger rep. I have just recently heard of the K1 brand. Familiar with Eagle back in my supra days. I hear the Carrillo is more for full blown race cars and not well suited for street vehicles.

Bearings- I am unaware of any aftermarket Main and Rod Bearings. Thinking oem at the moment. I hear GTM bearings are OEM that are coated for higher strength.

Bolts- ARP head and main studs.

Gaskets- OEM head gasket

Anything else I may have missed?

Thanks

Check out this thread: Engine Build Thread

Lots of good info in there. Hope it helps!

I have read the above thread, some really good info. Has anyone put some pricing figures together for labor on the basic short block build up. Parts come in around ~$2500.

blackonorange · 01-07-2013, 11:38 AM

Labour will cost double that

You really don't need to do that I made 516rwhp 383rwtq stock engine with a GTM SC kit on and it is reliable all day, save your money and put it toward your SC or TT kit.

BlkNismo · 01-07-2013, 01:25 PM

There are guys running even more power then your posted numbers on oem internals, but what conditon will it be in 5 or 10 years from now. Running high numbers for a few dyno runs is one thing, but putting that power down on a daily basis for extended time period may pose problems that could be prevented. I'd like to do it now rather then later since the engine will be out for the tt install.

I think you are reading into something that's not really there, go thru the forum and see how many people have had failure of their engine b/c of this not many at all,your consern was a question I ask Sam at GTM b/f I bought my kit he said these engine are good stock to about 550rwhp passed that your really pushing it.

I understand what your saying, I have only heard of 1 motor ruined that was fi'd.

That my point these engines are built very strong all you need is a good kit,a good install,and a good tune other than that drive the sh!t out of it.

BlkNismo · 01-07-2013, 02:08 PM

My major concern is longevity. Can oem block continue to be reliable 5 or 10 years later. Only time will tell, we have only been fi'd at most for what, 3 or 3.5 years.
But yes, at the current time frame, the vhr has shown to be quite stout.

When I had mine on the dyno John did like 10 full runs back to back b/c there was something he was watching for I just stood there and watched and didn't sweat it at all.

edub370 · 01-07-2013, 02:20 PM

ask digitonium. he's put like 25,000 miles on his boosted setup (aprox 470whp) with a canned tune.

Glokwork · 01-07-2013, 04:08 PM

I would love to build my motor so I could turn the boost up and have peace of mind. With that being said, I have a completely stock motor, clutch, flywheel and csc making 551whp 482wtq all day

Mr.Squeeze · 01-07-2013, 07:13 PM

OP how do you plan to drive you car ? there are plenty of people with well over 500 whp stock motor and ton's of miles. The reason I ask this is because a friend of mine had a TT 370z making 550whp that blew up. The car was drivin hard for 13k miles and shot a rod right out the side.

Too many variables here to give OP a straight answer.
