D16y7 Mini Me Vs Full D16y8 Swap

[dxasarous]

A Mini me swap is the most cost effective way to go. Just make sure while your in there to replace the pistons, rods and headgasket. That way your car could atleast be ready to support some boost, which is what you need to keep up with the dohc's out there.

yeah keep up with stock dohc's

[dxasarous]

Unless you plan on going all the way and getting 400+fwhp, it is cheaper to do a mini me and get some boost than to swap.
If you still want to argue, you can talk to these guys. They will be more than happy to run your car, that is if you car is a dohc.

last checked Calesta, you aren't the lord of this forum. As far as the info posted being "Bullshit," my local honda peformance shop, who has done over 1000 swaps, advised me that because the gearing is longer the Vtec would kick in sooner.

Oh, did I mention he is a honda trained mechanic from Japan?

I'd find another shop, cause they don't have a clue to what the fuck they are talking about. It's bullshit.

1. Taller gears means that the gear is longer, which makes acceleration slower. For example, 2nd gear is taller than first gear, which is why acceleration in 2nd gear takes longer.

2. VTEC is RPM dependant. You will actually hit VTEC sooner in a shorter geared tranny, because it's easier for the engine to accelerate. With the longer geared tranny you will be in VTEC longer, because you will be going to a higher top speed in each gear...but it will make your acceleration slower.

Shorter gearing = better acceleration
Longer gearing = higher top speed

End of story. Find another shop, and maybe find some knowledge of your own before you try and pick fights with people who actually know their shit. I don't care what shop you go to, who their mechanics are, or where they're from...they're wrong.

The funny thing about this whole thing is that it is a thread that is over a year old. Also nobody has yet answered the origional question right.

I thought it was answered by Mike pretty well.

In most cases for a mini-me compression is higher like Mike stated, but in the case of a y7 with a y8 head, you wind up with the same compression of a d16y7 (9.4:1) compared to the 9.6:1 of a full d16y8.

Actually, you'll get 9.96:1 compression. The Y7 pistons might have a deeper dish than the Y8 pistons, but they're also flush with the deck- the Y8 pistons are .027in in the hole. If you calculate the compression with the Y7 disk and the Y8 piston height, you get 9.4:1 compression.

As far as I have known, the Y7 and the Y8 have the same combustion chamber volume.
