Though I've been very busy with work, I want you guys to know that I haven't fallen off what I like to do and that's build fast cars and drive them fast as well. After my 1990 CA18DET powered sentra got rear ended last year, I spent alot of time searching for a new shell. This would prove to be most difficult because these cars aren't in abundance like they used to be. I found a 1988 4dr Sentra (white in color) was eager to just swap everything over. But I had promised my self that I wouldn't come back to the set with yester-years set-up and I meant what I said.
Today I tore the engine apart to be nosy and see how the internals looked after 17,324miles of hard-core driving, two stepping, 8300rpm dump-the-clutch launches and just straight-up abusing the CA and to my dismay, no spun bearings. However, the #1 main got some debris in it and it needs to be changed, but other than that, this engine is tight work and I did not and will not disturb the pistons because they're in excellent shape and not coated with too much carbon.
This issue with the cometic gasket that most are having is still puzzling to me. I pulled my head off from the block and the cometic gasket was very dry, except for a little coolant from the head. Since I'm changing the head for my ported unit, I thought I'd give this headgasket thing a closer look and I've concluded that it has to be a user error issue because I can't see the difference between the 3 gaskets I have. But don't take my word for it, feel free to do your own tests (My cometics seal pretty good).
I have almost finished the new sentra's wiring since I'm heading for a color change with the white engine bay being painted black. In case some have forgotten, I've also completed my fully built CA and am ready to place it into my drag sentra. This sentra is my highlight as it has some of the best stuff money can buy for example: JUN solid lifters, Jun valve springs, JUN 272 10.5mm camshafts, heavily ported/polished and modified head, Wiseco pistons, Pauter rods, knifed-edge and lightened crank, 9 lb flywheel, ARP studs on the top and bottom, aftermarket high volume oil pump, ACL bearings, NISMO 1.2mm headgasket, custom transmission, custom axles, custom intake manifold, 75mm throttle body, Ksport coilovers, and a bunch of other goodies that takes forever to mention.
The daily sentra gets a new intake camshaft as I will be using a Tomei 270 8.8mm to replace the HKS 264 8.mm. The HKS 272 8.5mm will remain on the exhaust side, but the new head sports tomei high lift valve springs. The daily sentra also gets 1000cc injectors in place of the 750cc injectors which are now on my 1993 S13 silvia/CA18 converted 240sx that's nearly done. Each of the vehicles I spoke of will be managed by Simple Digital Systems or SDS standalone engine management systems. I am my own programmer/tuner as well as my own builder, so I have no one to point the finger at when something goes wrong, but my self.
And last, my 4G61T swapped 1995 Hyundai Elantra has been down for over a month with a well blown or smoked headgasket. After nearly 3 years of reliability, I tried to push it hard with too may adults in the car and the little 1.6 DOHC engine told me to go to hell and shut down. I've been building it's replacement killer which is a 4G63T while at the same time building CA18's, so having 3 engines on engine stands staring me in the face everytime I go in my garage isn't quite a cute sight, but all is nearly done. I also added a LSD set-up to the hyundai's new eclipse gearbox, so that ate-up alot of my time as well.
In closing, I know this is a long post, but it's only fair that I share my car stories with you guys like most of you do. I got some nice cars coming out this race season, so stay tuned and let's see if it can get this built CA to produce upwards of 600whp! .
Later,
