I bought a 00 hatch today for a very good price mainly because the shell was flawless but it ran good to. The guy was a older family guy and new nothing about the car other then it was turbo'd. He took me buy the local honda dealership to talk to the mechanic he bought it from. I could only speak to him a few minutes he was finishing up his lunch.

He told me the car had eagle rods, i believe he said weisco pistons i can't remember and a block guard and he put it together he said it was 9:1 compression. He said he had put a mild/small cam in it but he had forgotten the name. He said the valvetrain was bonestock other then that. It has a ramhorn and a small t3 turbo but pulls pretty decent for 10psi and spools up really quick probably a mid 12 sec car pretty easy. It feels has quick has my old k20r EK on motor but that car was heavier probably, this car makes around 210-230hp. The car is alittle noisy sounding the mechanic said it was from the build but none of my other b-series turbo motors were quite that noisy its not terrible just alil noisy.

I drove the car over 3 hours home no problems but a SOHC vtec is a new world for me i've done stock sleeve b16 builds,2.0 builds etc but i know nothing about the d-series.

The car was tuned on chrome or uberdata i believe because it was street tuned by someone popular in MD. I don't even think the mechanic new what software they used honestly.

What is the potential power limit for this motor safely on pump gas?

Does this info seem right to you SOHC guys?

The guy i got it from said that he was told that he should buy a 3 bar and turn it up to 15psi by the mechanic the previous owner.

The only issue with the car was it idles down really low like it wants to cut off but don't just stumbles till you give it gas. And it does have a million t's on the vacuum lines i can probably get a vacuum block and it might fix that.

 

In a perfect world, D-sleeves can take a lot of power. With crap tuning, they'll shatter like any other Honda motor. Eagle rods and Wiseco pistons can take as much as your sohc can make, as long as you don't over-rev it. A stock valvetrain w/cam should not be taken over stock redline.

I have a very similar setup, except I have a stock head, but plan to use a head that has a Zex/Comp stg2 cam w/aftermarket valvetrain. I'm aiming to max the turbo out, which should be 275-300whp. When you're ready for a retune, you can get a drop-in replacement Omni/Hondata 4bar (43.5psi max) MAP sensor, or a cheap Motorolla/Freescale 2.5bar (21.75psi max).

The only way to get an idea what the power output is would be to dyno it, or measure the turbo's compressor and turbine wheels (both large & small sizes) to w/in 1/32". Usually turbos that get decent boost before 3500rpm on a D16 are rather smal.

 

It is a small T3 turbo i get full boost 10psi by around 3500-4000rpm. The have the redline set through a light in the dash at 7500. I thought the vtec motor revved to 8200 or is that just with b-series?

So with a blockguard, rods and pistons and 9:1 compression can the stock block sleeves handle 250-275hp safely on pump?

 

I wouldnt want to take that D16 to 8200, I dont think the valvetrain is setup for that kind of action..

 

FYI Blockguard do NOTHING. I've seen several cracked sleeves with blockguards. With froged pistons and rods added, your block will handle 400whp. You will want headwork (at least cams) to make over 300whp w/o resorting to high boost. You'll also want headwork if you want to make any power over 7k. My stock head' HP peaked right at 6900, and a larger turbo won't do much to move it higher.
