Guilty . Let's see if my motor even runs first. It's the first build I've done entirely myself, so for all I know, the motor might blow up the first time I start it and I'll have zero hp.

At the same time, who does run 400whp everyday? I know I'm not going to; nor would I try it on anything less than 100 octane.</TD></TR></TABLE>

i do on 93 pump with DARTON SLEEVES.

And you could of done it on 93 with stock sleeves. Point being, you must have had a good tuner? Because one again, higher octane does not make the power just leaves more headroom for error.

Sorry but if I had a sleeved block I wouldnt want to risk it on crappy gas. You can still break it with detonation.

moral of the story - IN THE END IT WILL ALL COME DOWN HOW WELL YOUR CAR IS TUNED if you are making serious power.

then again one bad tank of gas and good by motor...

but yeah I still agree with the quote just as anyone should.

if money is no issue then I don't think D series would be the platform of choice.

I say use stock sleeves, drive it hard until it blows, then sleeve it like many of us have done...

It seems you are a bit misinformed. I have yet to see any actual proof that a blockguard has caused harm when installed properly.

This thread is pathetically full of so much misinformation I don't even know where to begin.

Blockguards do not block coolant flow and help prevent the sleeves from shifting in high horsepower applications, which can eventually lead to a cracked sleeve.

I'd have the machine shop do the work when my block is bored and honed and they said it wouldn't cost anything extra.
D-Series sleeves do not wiggle any more during high boost than a B series sleeve. In fact the D series sleeves may even be stronger than B Series sleeves. The smaller bore helps with distortion resistence from the moment of inertia. You should know this Mike, it was mentioned in a thread you posted. https://honda-tech.com/zerothread?id=1334530

When installing a blockguard there are special machining techniques that have to be used to actually have it make a difference. Just hammering it in there isn't doing anything good for you, its actually causing harm. It can cause your cylinders to become "egg" shaped. This info isn't from my personal experience but from the "professionals" in our game that I talked to when doing my research when I started.
If you consider using a basic file "special machining techniques" you shouldn't be building an engine anyways. Blockguards are file fit and tap into place. They do not get hammered in, or forced in, and they do not need to be welded. It is recommended that you hone the cylinder after installation, but this should be done on a newly built engine anyways. I have yet to see "a professional" actually provide cylinder bore out-of-round specs for a so called "egg shaped" block from a block guard. If someone acuatlly does have egg shaped cylinders it is most likely from improper installation of the blockguard or bad tuning.

From what I have seen personally a D is just not a strong motor, built or not.
D Series is a better platform than a B Series in many ways. The D Series engine itself is about 75 lbs lighter than the B Series, it has less rotational mass and frictional losses, less complex moving parts (which means less to break), it's easier and cheaper to work on, and the sleeves may even be stronger as discussed earlier in my post.

not to mention theres a certain satisfaction one receives after building an engine that is seen as inferior to the B,H,K,etc-series...
