My Little Silvia (S15 with RB26)

So i take it this is a drag car since you completely destroyed the squish area on the head?

Props on the build though. very nice. Personally I would have replaced the sheet metal with new pieces instead of adding weight with filler.

I did sheet metal but it turned out wrong so I removed it. That is fiberglass, not solid filler so the weight difference is trivial at best and makes no difference. The sheet metal blocked certain holoes that were in close interval to the headlight cradle. The fiberglass was easily contoured and blended to work with that obstacle.



Destroyed squish???? Are you nuts? That was done by Nagoya Precision with a tried and proven CNC program. But yes this car is meant to go fast and maintain high RPM, Drag would be cool but I ma thinking more along the lines of Silver State Classic.

O that makes more sense about the fiberglass.


But usually with the squish/quench removed it will detriment the drivibility of the engine, and the ability to modulate the engine smoothly.

Yeah, the glass seemed to be the way to go on that one
as far as squish it is ideal as I am not tuning for street drivability but pure power at top end. I am looking to run this car at 7500 plus RPM for extended periods of time. Since Races like the silver state classic are high speed races, I will need to be high in the RPM and Boost range (7500 and 1.4 - 1.8 Bar) for extended periods of time which kind of makes this mod ideal.

If this was going to be a highly modified street car I would agree with you and leave the squish area in, but this car will not be driven daily as the maintenance required for that would be extremely time consuming and kind of expensive plus the car will not be set up for that, should I decide to street it, I will just build another RB26 that is more suitable (something in the 600hp range) but 900 plus is not daily driver material on a RB26.

O. I thought this was going to be a street car.

I have also allways wanted to do the silver state classic. What kind of cage are you going to fabricate for that?

Good build.

Dunno, I am going to roll with the Safety 21 8 Point for a while get things tuned and make sure I am good to go, the cage will be reapproached once I get back to the States with it and am ready to run (current cage is mainly for prevention of chasis twist not really focused on safety with this one). Mainly because, there are alot of reputable shops in the states that will do it for a decent price and I will be able to be there and make sure things are done how I want them. I would not have that ability here as I would have to ship it to Mainland. Being a hands on type of guy, that would not be very cool with me.

I wish my car could MAKE 1.4-1.8 bar and run 7500+ RPM for extended periods of time...that's just intense. My turbo can't even handle that, let alone the engine.

As far as for your streetable 600hp RB, I totally agree with you there. That's pretty much exactly what I would have done...... I'm left speechless.

Amazing build *subscribes*

Removing the Quench zone (as you guys call it, the "squish area") allows for easier sweep through cycle. Yes, alot of drag racers fuck with that area of the head. BUT, they also do alot more than just remove the quench zone (they also add material to divorce the valves). If you ever go to the funny car or rai lcar races, you will see, that they always hide the heads or cover them with towels. They are quite secret and make a huge difference in the way a car performs, yes, maybe its only an extra 60 hp on a 3,000 hp motor... but ... wouldn't that still be "an edge"? (rhetorical)

My KAT s14 is a drift car. It has the quench zones removed. (it also has 10.14 : 1 compression YIKES!!!)... it works just fine!

either way, nice build

your build is really something we can all admire.

most of us..when we first get a car, dream up all these ideas on what modifications we want to perform. a good amount of them never get the chance to become reality.

you, are living that dream.
