While I was saving up throughout the months passing by, the 13B-RE that I bought blowned up was in the process of being rebuilt. During those times all I could think was "Damn, is it really gonna be worth dumping all this money on my car!" I figured I would go ahead and stick to that old saying of "If your going to do it, do it right the first time." It makes sense to the common mind. There is also another neat saying using the words: Cheap, Reliable, Fast you can only have two out of the three.
I saw this somewhere a long time ago I thought it was really true:
- You can have a car that is Cheap and Reliable, but it isn't gonna be Fast
- You can have a car that is Fast and built very Cheap, but sure isn't Reliable
- You can have a car that is Fast and Reliable, but sure the hell isn't Cheap!!
Okay enough with the sayings. I had the bought brand new seals, gaskets, fittings, etc for a complete rebuild. The new FD3S rotor housings I bought got their exhaust ports opened up a bit, water jacket modification, machined for pinning. As for the steels they were relapped, machined for pinning, and of course given a large streetport. I had 6 extra 12a dowel pins put into the motor. Since emissions is of not concern to Florida, anything to do with helping the environment is gone. I had the oil metering pump removed because I just couldn't trust something so old and very expensive to do it's job on my new motor. As for the UIM and LIM I had them port matched and smoothen all the runners alot <---actually required alot of welding. Lets just say if I were to shine a flash light into a runner, you would be able to see a tad bit of the actual light source. Alright lets get to the pictures. Sorry everyone, I cannot post pictures of the porting and pinning by request of my builder.
Polished eccetric shaft
S5 rotors with OEM 2mm 2-piece apex seals, also double sprunged
The upper intake manifold before and after. Do you see what I mean about alot of welding.
The lower intake manifold before and after.
after having all the excess aluminum removed
Lastly polished
And last the pinned,ported, polished bastardized motor composed of piece from all the other generations...my Cosmo 13B-RE block.
Since the FD rotor housings were brand new it would be a great chance to do anything to assist the motor in cooling. So I had the Water Jacket modification done at the shop. Exactly like this picture from racingbeat's website. Here's their explaination of the modification for those who wonder why:
"The Rotor Housing Water Jacket Modification is intended to improve cooling in the hot zone of the rotor housing to increase both housing and seal life. This modification involves cutting grooves in the water jacket in the vicinity of the leading and trailing spark plugs to increase heat transfer out of the housing inner surface. The modification can be performed on a new rotor housing, and is only appropriate for race and the most extreme street use."
