Talking Matt Dennison aka o-townFLA 2.3 GTX3076 REBUILD

Blog---> http://timeattackusa.blogspot.com/


2.3 MOTOR BUILD

A little insight of what's been going on with "Matt Dennison" aka "o-townFLA" or simply known as "Matt"...

All intentions were to go to a track day and instruct. Seeing everyone blast around the track or me sitting in the passenger seat wasn't necessarily*boring but the competitiveness in me wanted to be in the driver seat. So without fully going over the car I hit the "time attack" session... Bad idea...*

After the (2) TA session my car had a little more valve train noise than usual. Trying to figure out the noise at the track with a marauder of people you can only imagine all the inputs and ideas of what might be wrong. So while at the track we all finalized that we couldn't really determine what was wrong. Other than the new noise and that I was super low oil...

So I dropped the car off at Road Race Engineering to have their assistance. Within a few hours we have found the problem. A motor killing spun bearing...

So the next question was what to build, how strong will the build need to be and what all needs to replaced...


So the final build would be the following with a few new extras:

Jacks Transmission 2.3 Stroker*
- Wiseco pistons
- Manley H-beams
- AMS oil pan w/ scrapper

Jacks Transmission rebuilt head
- Kiggly HLA pressure regulator
- Cosworth M3 cams 280/272

Jacks Transmission rebuilt tranny
Front Mount Earl's oil cooler





I've always been weary of running E85 due to its inconsistencies. So I've always ran 100 octane making a decent 450/400 at 26psi. With this build I decided to bump up to E85 but would do it right...

- ZEITRONIX Ethanol Content Analyzer
- Walbro 400lph*
- FIC 2150cc injectors *
- Fuel Lab Fuel Pressure Regulator*

My current turbo setup is the cast HAFE manifold with a newly released GTX3076R bolted on.*













Well the blessed people at Road Race Engineering to include Mike, Rossy, Honda, Sam, Lod, Chris, Robert, Matt, Art, Ruben, Lydia, Gus, Rick and Scott have been a tremendous help and I will forever be in debt to them...!!!

I've seen your car a couple of times at RRE. Everytime I visit Road Race it just happens to be there and always wondered what was up with it. Who's tuning the car? Rick? GL with the rest of the build. I'll be following your progression.

I snapped a balance belt bending all my intake valves, the I was plagued with leaky valve seals most recently before I spun a rod bearing.

Scott Gray tuned my car and it has never had a hiccup

Got the motor dropped in yesterday. Still need to install the t-case for it to be completely installed... Had to wait on some gaskets or it would have been dropped in last week. But the worst thing was that when i opened the tranny box up Jacks Transmission had sent all of the needed gaskets in with the tranny. Oh well...

While the motor was out I removed all the EGR stuff...

Next up is to mount/install the Fuelap FPR, Zeitronix Ethonal Content Anyalyzer wired in, Walbro 400 install w/ it hotwired in, and install/mod some more aero...

Hope to get it cranked so I can get some break-in miles on the motor, swap out the old injectors for the FIC 2150cc's and get her dyno'd on 91 and E85...!

Track day plans are to hit up some HPDE for some shake down runs and then run Super Lap Battle/GTA in November to finish out the short track year...







Sweet Jacks Transmission packaging...!!!







We're off to the races....

SHE'S ALIVE...!

Amazing...! She fired up on the second crank...!

With the help of Lod's expertise and constructive criticism (who is also Formula Drift driver Joon Meang's crew chief), she fired right up. Help from not only Lod, but from all the pros at RRE have made this all a breeze...








After a quick 20 mile jaunt around Sante Fe Springs, CA I came back to the shop and drained the oil and cut open the filter for inspection of any type of oil conatamenation.... Results looked good...

So it's now officially time to get in some varying RPM break in miles...

Here's some craftiness....

I decided to make a front mount oil cooler setup but still utilize the OEM pusher fan. In doing so I needed to make/fab a new power steering cooler...

I removed the front loop cooler to make room for the larger oil cooler and replaced the power steering cooler with a smaller core more efficient. I also relocated it to the front right wheel well...







In the above pic, the oil cooler is just in a moc setup but will be fabbed to sit there...

At the moment, the oil cooler lines are looped. As I'm holding of on installing the oil cooler until the motor is broken in completely.*

The car is close but still far from total completion. Well to think of it it'll never be completed...

Still to do list

- route/fab/install oil cooler
- install Walbro 400
- install FIC 2150cc injectors
- install ZEITRONIX ECA readout
- install voltex rep bumper w/ modified brake ducting inlets
- install Binary brake ducts
- dyno tunes
- prep for track day
- track day, track day, track day
