I don't think so, they're built to hardcore your engine in first place lol.
However, since you're tracking your car then you may consider an oil cooler, it's recommended whether u're sleeving ur cylinders or not.

I know they are a little overkill, however, I have them so I was thinking about getting them put in while the block is at the machine shop getting assembled.... I was just concerned with overheating or higher operating temps during Road Course Racing.....

Ah, I was reading it wrong for some reason. I thought you were going to tear down your engine and just put sleeves in there cause you got a deal on them. Didn't make any sense.

simple flow chart, are you going to exceed 800 whp? no? dont do it, yes? sure but be very very picky who does it. alot of people have had issues with overheating and sleeves, i cant think of a single shop that would recommend road racing and sleeves for that very reason

You make no mention of bore size.
The Datron sleeves can be bored out to 101mm to give a total displacement of just over 3800cc but the problem then is head gasket sealing. There is not much left between the cyls & to my knowledge only cometic make a 101mm Head gasket & it does not have a stopper ring.
If your not going to boost it into the stratosphere or increase the bore size I see no reason to use sleeves.

its 100mm, and cometic changed awhile ago, they have been stopper style for years now.
doing a built engine without FI is 100% a complete waste your spending just as much money for a fraction of the output, even with a stroker your still going to make less then stock block FI guys for ALOT more.

Page 84 Cometic catalogue.
Vq35 de Largest Head Gasket listed 101.5mm Type MLS (non stopper)
Part #C4380-030.
100mm Gasket is available in MLX (stopper) which is what you would use if you saw the need to fit sleeves to get bigger capacity without a crank.
Agree with Jerry & others, that FI is by the far the biggest Bang for Buck.
As the OP does not say how serious he is going with Road Corse it may be that the class he picks may prohibit FI.
The list of mods does not include pistons & rods. IMO an absolute necessity & a far cheaper option than Datron sleeves

the 101.5 mm headgaskets arent even worth mentioning, they will never be used in a build unless the engine builder is an idiot. the largest bore the darton sleeves support is 100mm, so the 100mm is the largest you would use everything under 100mm is available in stopper style as well as ive built engines with them.
im not even aware of any place that keeps the 101.5mm on the shelf

Not sure if I had already out this in the post or not, but I already have the sleeves in my possession from when I was going to do an FI build.... But then I thought to myself, You already have 2 other Drag Racing cars, so I decided to do another Road Course car instead....
