Sounds like a nice build. Hope to see it make good dyno and 1/4 numbers. I'm curious to see how the meth kit works. I remember your bro and I talked about it a while back but never looked into it. Cool.

Seems like the 88mm build will become popular jajajajaja I still believe that A 88mm motor can produce same amount of power than at least a 90mm motor without the sleeves thats $1200 less to spend on power making parts jejejejeje

88mm and some compression sounds like a cheap alternative to the 90mm builds...wouldn't 88mm yield almost 2.1 liters....

This is not all the way true cory.

A SR16VE piston is 13.5 to 1 at 86 mm. When you go up to 88 mm you will gain another .4-.6 in compression. Thats 13.9-14.1 . Every 1mm in piston size is good for .2-3 compression raise depending on the size of the head combustion chamber.

Just asking how an 88mm motor can produse the same amount of power as a 90mm motor.

If everything is the same and you have a 88mm motor vs a 90mm motor The 90mm motor will make an average of 15-20 WHP more than the 88mm motor.

Its simple a motor is an air pump and with larger pistons it just moves more air everything being the same

88mm motor will still produce decent numbers i believe with a full port job,kelford cams and 4-1 custom header

2.0-2.1 liter hondas make 220-250 whp all the time

no one is saying it wont make decent numbers just will not makes as much as a 90mm motor because of the obvious.

a 2.1L 88mm VE motor with Kelfords should make 235-245 WHP


2.0L = 220-230 86mm x 86mm
2.1L = 235-245 88mm x 86mm
2.2L = 245-260 90mm x 86mm
2.3L = 260-275 92mm x 86mm

Well I've been dealing with cp for the last few weeks trying to get a high cr piston and they said they are una ble to get me anything above 13.5:1... but like you say. Its true when u increase bor or stroke for that matter cr will increase with the same size crown.. so why are they telling me they can only get 13.5:1... My 12.5:1 pistons have very very little extra room for a dome because of the angle of the valve reliefs..... what am I missing

IMO those calculations you are making are overrated...

Sorry I didnt explain myself well it will make same amount of power with the same money invested it just my .02
At least fur us here in PR the can get the machine work a lot cheaper than in the US but cant get the sleeve install same price as u over there that doesnt have to deal with additional shipping charges...
