Something tells me this engine is quite restricted/de-tuned in some way from factory...

12.5:1 CR
D4-S
Completely new Yamaha heads (?)

Yet only 200hp at 7000rpm?

Sounds fishy to me. The best thing is, IF it is restricted as much as I think it is, then everyone's going to be able to gain a VERY good amount of power with simple I/H/E and ,maybe cams too. After that, raising the rev limit to 8000 should still be reliable and give an extra bit of power (when coupled with the cams).

This car is looking better and better every day!

Due to the D4-s toyota injection it would make sense that it would use a toyota programmed ECU... Which sucks for those of us who would like to modify the cars.

I could care less for massive horsepower and torque like most of you guys but I still feel the torque output is too weak. I want the torque for usable power not drag races or fighting off 5.0 Mustang GT's. I would've been happy as hell if this engine was a FA25 making 220-240hp/180-190 tq in a 2,750 lb RWD body.

Yea basically.
Although I don't know about raising rev limit, 86mm is a long stroke.

In case no one pointed it out yet in this thread, 12.5 is definitely CR, the kanji means CR in Chinese too lol. Have some homework due in like 10 minutes, I'll examine that picture later. Nothing interesting that I saw so far though.

K20z3 is 86x86, 11.5CR and I rev can rev it to 8500 all day

I think someone ran calculations with Subaru block dimensions before, the rod length isn't that good even with this modified 86mm stroke I think :/

When high load
Direct inject
High compression make sure high performance

When low and mid load
Direct injection and port injection according to situation make sure it improved fuel efficiency and reliability



Overall length 4240mm
Overall height 1285mm
Wheel center to center length (Sorry for not native English) 2570mm
Interior space length 2570mm
Front seat to rear seat 700mm


Back seat available for two adult (able to fit)
They can sit straight in back, but driver still have good view of the back window (Japanese man size I believe)
The adjustment of front seats are using some sort of sliding stuff, (this is the best I can understand)

As long as this car (modified) can beat the current pass champion the RE-A Rx-7 who beat several cars lighter or even boasting 3x more power. Ill be extremely happy.

200hp is a decent low cost starting point...sure we could get 240/180. But why? I sure don't see any reason.

If this was a brand new sports car, with a brand new design philosophy. 200hp is not enough IMO. But when I am specifically told that a sports car built with the ae86 in mind, I am not expecting much at all in the power department.

If i were an automaker, and i were to build a entry level sports car today for the general market, with a low cost figure, id sell a car with less power than the FRS, and offer a PLEETHORA of aftermarket options. And id still make massive profit.

This is a Smart and strategically sold sports car...not a sports car to be built for bragging rights. or FRS is faster the X vehicle...

If i wanted a real sports car...FRS isnt it.....but i don't want a real sports car..i just want the feeling of being connected to the road again like no other cars have given be since the 70s/80s/90s build types. I want to be able to feel the asphalt in my hands through the steering wheel again. I want plant my foot into the throttle and throw the car at any given corner and not worry about having to much wheel spin and power. Of have to worry about throttling/feathering/understeer/oversteer. I want to have a car that makes me feel like im at peace when i drive, regardless of speed.

I truly hope this is it....

otherwise maybe 2650 is still too heavy...and 200hp is still to much power for what im asking to feel.

Yes, it is CR. 压縮比 = CR

I totally agree.

I think in order to meet the Euro V emissions they have had to restrict the nuts off this engine.

Im almost willing to put money on it that once you've ditched the CAT(s), removed the stupid EGR, upgraded the exhaust/intake, pushed the rev limited back and remapped the ECU you'll be seeing 220-230bhp. Seeing as its got VVTI, I dont even think you'll need to worry about even touching the cams.

[WingsofWar]

^ i dont recall seeing VVT being part of the design..from subaru or toyota

[SHINCHU86]

yeah say what now?
that brings up a point. why no valve control? too expensive? might have been worth it for an extra 30-40 hp.
(dont lump me in with the complainers! its more than my stock 240sx had!)
just toshing it out there.

also i think the pic with the hand on the door sill is showing how to use a cushion to aid in getting out of the car?
when i got out of my 240 with a bride zetaII seat with nagisa rails (LOW!), i used to put my left hand on the door sill and pivot to a standing position that way. its a habit that even carried over to my camaro. anyway, a pad there would make sense for that.

Thanks a bunch Fred!

That bit about fitting adults in the back is intriguing.

Not 30, that would need a pretty big rev limit increase, but 20 is pretty realistic, increase lift to maximize power at like 7400 instead of 7000, get like 15hp out of it. I am looking at the picture and I don't see variable valve control (cam phasing does not count in my book, because it can be implemented without any serious changes to the valvetrain), I think this definitely isn't going to stay forever.

Yea I think those new emissions laws...restrictive catalytic converters or something. Sucks
