Blown Motor, Engine Rebuild/Replacement.

Best to stay away from any shops in tampa

COSMO

Mind if I ask why in keeps going back to the shop?
I can honestly say that bryan from bbr has taken really good care of me. Great communication, updates almost daily, now consider he had to rebuild an entirely new engine and I'm having him do some top secret custom work for my new setup.. I would highly recommend him for anything and when I buy my next z or supra I'm sending it there for him to do his thing..

I trusted a shop that is big in GTRs that I thought was up to the task. At first the car was never being worked on because 100 GTRs were more important. When I finally got them working on it they sent it to their fab guy where it sat for 6 weeks and when it came back the hood couldn't shut. After going back to them for 3 more weeks it came back mid December. Over Christmas the shop owner fired the only guy that knew what he was doing and decided he was going to do all the work with a couple green assistants. It took him months to get it running right and for his friend to tune it. I had it home for a couple weeks and was on my way to Sebring for a track day when I got off the interstate on to a busy highway and stopped at a light in crazy traffic and the temps started flying up. By the time I could get it out of the road it died, the engine was done because of a leak in the radiator. I have it at a new shop now and so far they have their act together.

Is it forced induction? I'm guessing it had to be causing it to over heat. With mine I installed a thermostat from a g37 that opens 10 degrees sooner than the oem for the z and went an oversized radiator and a vent hood... Did you blow a head gasket and damage anything? heads?

It a Stillen supercharger, sad thing is I dropped it off running perfect. They changed it to air cooled and I had level 10 build the trans. I had hit something in the road a few weeks before I dropped it off. I'm guessing I damaged the radiator then but it hadn't started leaking yet or it started real small. I was running water and Water Wetter so I didn't smell it, I will be running coolant again until I know it's right. It didn't blow the head gasket but the head warped bad and the oil and water went around it.

It was a CSF triple pass radiator ( I don't believe it was their fault) and it has a vented Hot Wheels hood ( the biggest vents I could find) I also got the Stillen bumper so I could move the oil cooler and trans coolers away from the radiator. Before the leak the car always ran very cool.

Yeah it must have pin holed it somewhere and the heat just made it expand. I also have the csf but not the triple. So far so good on it not leaking but then again I don't track my car either..

It was where it attached to the passenger side end tank. It looked like the impact had pulled it out slightly. I did two sessions at Sebring the weekend before without any problems or signs of a leak. It must have have started leaking more why I was on the interstate but my wife was behind me and didn't see anything.

Just another quick update, transmission back on, turbo kit re-installed, bigger charge pipes being fabbed up this week and hopefully on the dyno next weekend... Like I said before I had to order a bushing for my hd csc and os giken twin clutch which held things up for a few days..
I'm now debating on buying a good lsd but don't want any additional noise. I have always thought of a lsd was mainly for drifting. Any thoughts?

I didn't realize my car had an open dif and it about caused me to crash the car into a wall at Sebring, if you do any hard cornering/ tracking it's much safer with a LSD.

What about overall traction? Just ready to get my car back.

JWillis72

It helps straight line traction when you are on it hard because it's harder to brake two tires loose. Where I feel if most is coming out of a turn hard and fat, with an open dif if you unload the weight off the inside tire and try get get in the gas the inside tire starts to spin and the outside starts to slide. On our cars when that happens the yaw sensor kicks in and cuts power, I had a group of cars behind me when it happened that came very close to hitting me while I was spinning without power.

The other place real lsd helps is on even surfaces. If you are accelerating hard you lose traction and will get wheel spin and fish tail, with a clutch type or Wavetech rear diff, the are locking so it minimizes fish tailing and spinning so the loss of acceleration is lessened significantly.

The misnomer in drifting is that traction isn't important, it is just as important as road racing because you cannot control your drift without traction!

Any recommendations on a good lsd and what about the install? Is this a weekend job or does this require a professional ? I can honestly say I have done everything but a gear change, etc..

JWillis72

I sent mine to Z1, I was told it's requires a professional. I picked up a open dif of eBay and sent it to them then sold mine when it came back. I have a quaife in mine and it doesn't make any noise that I have noticed.
