93 BB Base Half-Bridge GT42R Project

Hey, recently I blew the engine on my 93 BB Base model RX7. This was 4 weeks before Steve Kan was coming up to tune my car. It blew 4 days before I had to go back to school in Melbourne, Florida (FIT). I took it to Davinci Motorworks in Belleville, IL to have it compression tested. The rear rotor was fine, but the front rotor was not so lucky. No compression what-so-ever. So on my last day at home, my dad and I ripped out the entire block and put it on a pallet.

My dad sent it to RX7Store after I left to school. Xavier will be building my shortblock at RX7Store. He will be doing their Stage 4 (Half-bridge) motor. I believe that it will be a small or medium bridge, but I am not quite sure yet. They are also using 3mm apex seals and they are dowel pinning the motor as well. I am also getting the GroundZero LIM and gasket port matched with the motor. I am going for big numbers this time.

When my motor blew, my GT42R turbine wheel was slightly damaged. After showing pictures of the damage to Sean (A-Spec tuning), Xavier (RX7Store), and Steve Kan (Gotham Racing); I have decided to keep the turbo the way it is and see how it preforms when I get the car dynoed. All of these engine builders told me the damage was very minimal and it should only slightly affect the spool up of the turbo. Also, since the GT42R turbo is pricey, I have decided to see how my damaged one performs. After I get the rebuilt block put back in, I am having Steve Kan tune the car. The new motor won't go in until I get back from school after finals week in mid-May.

Smile Good stuff

Good luck to your rebuild I had my motor rebuilt by Xavier too, he did a great job on my ports, Stage 2 and I'm in the progress of having the engine ready to start along with a GT40R. Keep us posted and I hope that everything goes well.

Actually I work very hard and earn my own money. My parents refuse to pay a dime for anything related to my car, so I have to pay for everything myself. My mom hates the car because it makes the CO detectors go off in the house - LOL. I pay for everything on the car myself. Its actually quite simple, its called get two jobs and work your *** off, which sucks because after you are done, you still have no money.

Today, I sent off my steering rack to Maval in OH. They will be converting my power steering rack to a manual steering rack. The cost was $215.00 to use my good, low mileage core. If you don't have a usable core than tack on an extra $65.00 to the initial cost.
I will be keeping my AC though.

Well, I couldn't have even tried until I got home in May, and as you know time is a big issue with me right now. I am trying to get as many things as I can done now while I am still in school before I come home in May. Then the pressure of getting it done in time will really be on!

Since Defi decided to quit making their D series gauges I had a hell of a time trying to find them. But, I managed to find the two that I needed, Oil Pressure and Oil Temperature. I also got FlyRX7's 52mm "Quad-Pod" Center Speaker Gauge Pod in the mail. I had his "tri-pod" but I needed one extra pod so I sold it and got his "quad-pod." I also ordered a Greddy Type RS BOV that will be swaped out for my current HKS Racing BOV.

I have the GT42R. Yes, it is made by Garrett. 35R is smaller than both the 40R and the 42R. The 40R is smaller than the 42R.
