Blog Title: 2.4 Liter G4CS Build
1999 GSX in Tracy, California

The is going to be a track only Road Race car. Based off the '89-'91 Hyundai Sonata G4CS engine, it is identical to a 6 bolt engine, with the exception the deck is 6mm taller and bore slightly larger, giving the extra .4 liters of displacement that will yield lower spool times. This will be perfect for a road race car where spool times are a huge factor in how fast you can get out of a corner.

At the same time this engine is being built, the car is being restored similar to how Eric and Brian restored Eric's car. Both of these gentlemen are trusted moderators of this website (turbosax2 and snowborder714) and have been a great inspiration and help to the dsm community and me. The fusebox is being relocated similarly, as well as interior rewire.

The end result I hope is a CLEAN road race car, capable of being shown at car show, but powerful enough to win races. I invision the vehicle with an interior, and a stock exterior with the only modifications being functional vents/lips/diffusers.

My goal is to have this on the track during the 2010 Race season, lets see if money stretches that far!

2.4 G4CS build.. Its ALIVE!!

Posted 04-06-2010 at 01:32 PM by Atuca (2.4 Liter G4CS Build)

The car was first turned on monday night, March 29, 2010.

There were almost aboslutely no problems.

The only problems were problems that had I been given more time to complete, would not have been issues. The battery relocation ended short, at the passengers feet using the stock battery cables. I had already sold the bracket and tie down months before, so for the...

G4CS Build: Into the DSM!

Posted 03-22-2010 at 12:22 AM by Atuca (2.4 Liter G4CS Build)

Today is a great day in Atuca DSM History....

the G4CS is in its home, my DSM

Beginning this blog, I got myself a GM alternator from a junkyard car. It was the newest I could fine with the least amount of miles, there were ALOT of Saturns laying around lol, I'd guess a couple dozen or so.

G4CS Timing belt Installed!

Posted 03-11-2010 at 12:42 AM by Atuca (2.4 Liter G4CS Build)
Updated 03-11-2010 at 10:36 AM by Atuca

To begin I pulled out all of the bolts on the timing side of the engine and put them back in all torqued to spec and using blue loctite. The only bolts that didn't get blue loctite were bolts that got red loctite, like the crank bolt and the oil sprocket nut.

Well I been cracking away at the build more silently lately, trying to knock this bad boy out! Well today I am a few accessories from completing the engine.

To catch you guys up, here are some pictures!

I worked on getting some of the accessories on the timing belt side while I was waiting for some assorted random oem parts to come in. One of the harder parts was taking...

G4CS Short Block and More Complete

Posted 02-07-2010 at 12:12 PM by Atuca (2.4 Liter G4CS Build)
Updated 02-07-2010 at 10:32 PM by Atuca

My first engine build is coming along pretty smoothly, aside from taking alot longer than expected. I had ALL 3 of the other local DSMers in Tracy come out and pitch in, they were working on my car, their cars, there was beer, music; its the atmosphere I been missing for a long time.

I already had redone the crank (thanks for the input last time dsmtuners!) and when my friends all...

G4CS Short Block Assembly

Posted 01-24-2010 at 12:47 PM by Atuca (2.4 Liter G4CS Build)
Updated 01-25-2010 at 10:41 AM by Atuca

Well yesterday was a fun day!

While I had to wait for a friend with the tools to work on the pistons rings, I contemplated what I could work on. So I just began preparing the block.

First off I tried to get working on the Balance Shafts. The bearings are stuck in the block and I tried to get them out. I was told to use a 32mm socket, but when I used mine it was too small,...

G4CS Machined!

Posted 01-22-2010 at 04:36 PM by Atuca (2.4 Liter G4CS Build)

Well sooner than expected, the engine has been machined!!!

Rob's Machine Shop out in Hayward California pulled a fast one for me, having the block done in a little over 5 days. (two of which were weekend) Very satified with their work.

My crank only needed a polish, which was nice!

Block and head were both decked for the Cometic HG.

2.4 Liter G4CS build - Tranny Problems

Posted 01-18-2010 at 10:55 AM by Atuca (2.4 Liter G4CS Build)

Well with news my engine is going to be done this week from the machine shop, I had to start spending some cold nights out in the garage.

I started working on my Tranny and shifting assembly. I started by jb welding the rollerskate bearings together. I went ahead and did all 8 and figure I will either sell them or have them laying around as a DSM gift to a DSM buddy who helps me out...

Well I know it isn't what you guys who deal with it all the time would consider amazing, but it snowed for the first time in 15 years in cities around california this past week. Its been COLD!

But I did still try and get some work done. Defying the cold with the light from my craftsman lamp, I finally got the firewall respectable. It isn't perfect, but after hours of scrubbing with...

Last two weeks I been continuing work on the Interior.

I got rid of all the sound deadening material! I didn't have easy access to dry ice, so I went at all of it with a plastic scraper, a heat gun, and some goo gone. It took alot of time, I want to say.. two weeks since last update right? :P I would NOT reccomend this technique if you have access to the dry ice, but this did work,...
