Just picked up a 1990 Ef hatch to do a budget build...
D16z6

Mill head .110"
Comp cam 59500
Rev valve springs
Ported and epoxied short turns
P29 pistons 75.5mm -17.43:1-cr
Stock rods w/arp bolts
Moroso oil pan
Cable SI tranny
E85
Obd 1 conversion

My goal is to make over 180whp

That's I pic of the port before the epoxy and the final shaping...

Nice build. It will be interesting to see how it will turn out. Subscribed.

considering U have all the clearances I do not see how U get 17.43:1

He took a ton if material off the head. Good luck timing that setup.

The chamber is only 23cc after milling .110"

180whp single cam BUDGET build?

what is your budget lol

Topoyiyo

I'm a machinist so all the labor porting,boring,milling is free and with that high of a compression I don't think it ill be that hard to hit that 180whp mark.

TinyD2point0

this looks like it will be a good build. very interested to see the final outcome

koczeka

I saw that milling, still
Clearances?!

P29 is this one?! Very little dome.


MAYBE would yield that high with sg. like this:

I was thinking the same thing. Doesn't mean it can't be done though.

Looks like a good build, not sure if E85 will have enough octane to run the timing that the engine wants but would be a start. Keep us posted!

Topoyiyo

I had a similar set up but with a mild d16A6 piston and 23cc chamber and it ran great but this time around i desided to run a little more compression...

good luck man i would love to see how that turns out.

What epoxy are you using on the head?

98vtec

you are not planning on using pump e85 are you?

I ask because you have to be careful with what you are actually receiving at the pump.

I'm curious to how the cam degreeing will work out.

Madmood

Maybe you should be playing with a piston more like this.



This is what I have been using in one of my d15's. Stock rods & rod bolts. Milled head , .005 off the deck. This is what 17:1 actually looks like.

It will not run at all on 92octane. It will get itself out of the garage with 100octane. But it loves 114.

I have done the p29 setup and found that the aftermarket (ebay) p29's have very weak ring lands.

98vtec

lol. whats the weight on that thing?

Madmood

Hahaha Blake. I cant remember. I did weigh them when I got them back in 09. This was the first set that ARIAS actually made specific for the d15. A lot has changed in the last 4 years thats for sure. My next set will be much lighter I am sure.

The engine has been together since 09 and have never had any issues. I like reliability.

Topoyiyo

Not 100% accurate but I'm going to pre assemble and CC the motor for exact Compression results

you forgot the head milling of .110
and how the hell did you get 23 chamber volume

Topoyiyo

I actually cc'ed the chamber myself so that's why I changed the chamber size but here you go I did it the way you said and now it says like 18:1

Today ill be at the shop so ill post some more pics
