Needs to ReBuilt any comments would be appreciated
 
Hey guys i'm looking to get my first 3rd gen engine rebuilt and looking forward to GoodfellasFD3s to do the job.

WEll my questions are, i wanted to run the GT35R (35/40 - .86ar) What is the best way to do this and i also wanted reliability too or should i stick with the stock twins, i'm looking to get around 375-400whp with stock or 400-450whp with GT35R. If i can get those number with stock i'll stay with stock to save some money but if not then GT35R it is. thanks for your comments guys.

I will get the Apexi + commender
Custom V-Mount
Custom Exshualt
Fuel Pump, Regulator and Injectors (what would be best, Top feed or side feed) and should i get the fuel rail system upgraded too
New Clutch and fly wheel

What else should i be doing to this to make it safe and best power Looking to spend around 6-7K for this car thanks alot guys

first things first you're going to need to spend more money, secondly street port the motor, your other parts sound good so far

If Rich and Ihor are doing the work for you, either of them can certainly give you very solid advice on how to properly modify the car. Your power level expectations are on the high side for stock twins.....

Your budget is woefully inadequate if you are including the engine rebuild. A good rebuild with new rotor housings and all new accessory parts (hoses, lines, etc) will chew up a pretty good chunk of your budget. You will definitely not be anywhere near affording that GT35 kit.

375-400hp is not reasonable on stock turbos. It's too hot and the turbos won't last long. 350 is more reasonable on stock turbos.

For a single turbo install, since you need to upgrade everything else to go with it, I think your budget will grow. $5k for the rebuild and associated things (wiring harness? OMP lines? Vacuum lines? coolant hoses? FPD?) Then another 3-5k for the single setup and any fuel and computer upgrades you need to make it work properly.

i've seen on the web some rebuilds should only cost around 2500 - 3k but.. or u can just get a jdm 13b w/ like.. 20k miles from ebay. but, these guys pay the top of the line rebuild, thats why dgeesaman said 5k for the rebuild.. =/ to me, it shouldnt cost that much.. but, u know, just some advice b4 u go and blow a ton of money on a rebuild.. good luck on your rebuild.

dgeesaman 05-16-07 05:53 PM

Well there is the rebuild itself and then there is the labor to pull and replace the engine. Then there is the stuff that is smart but not absolutely necessary - wiring harness ($750), injector service, etc, etc that add up quite a bit too. I think nowadays it's most accurate to assume $5k will disappear by the time the car is back on the road, and that's not including mods done in the process.

Go with the larger 1.06 a/r 35R. You will not be dissapointed and will easy make the power you are looking for. I ran one for a while. Shoot me a pm, we'll talk.

People that have owned their FD for 2 months, have never rebuilt their motor, and don't really know anything about the car should generally not be posting advice.....

The Rx7store has a good rebuild price -- $2150 for a base rebuild. This is just a seals and bearing replacement and doesn't include any new hard parts. That price doesn't include shipping the motor (both ways), R&R of the motor, all the new hoses, vacuum lines, gaskets you need to actually reinstall the motor. It also doesn't include replacement parts like solenoids, wiring harnesses, etc. Even for a base rebuild, you could easily drop $4-5k installed TO DO IT RIGHT. Now add new rotor housings, porting, maybe 3mm seals, and you are adding $1500+ to that total.

Definately not a bad price. Used motors from an unreputable source are a crap shoot. I wouldn't waste the money.

Have anyone ever got their engine rebuilt by GoodFellasFD3s yet? From what i understand he only charge about $900 in labor to tear the engine down, inspect, port and built. Now are i have to worry about is paying extra for the master rebuilt kit from Atkins so thats another $1000 + plus one used rotor and housing $250 from GoodfellasFD3s. So for all this is under $2500 that's cheap i don't know why you guys add it up so much is there anything i'm missing? or not calculate in?

$900 Labor, tear down, inspect, clean, port, rebuilt
$1000 Parts (master rebuilt kit from Atkins)
$250 one used rotor and housing
$300 Vacuum hose replacement

Now is there anything else am i missing still?

dgeesaman 05-17-07 11:32 AM

It looks like your prices are laid out for a stockish rebuild on a budget. Which is fine, and these guys are among the few out there I would trust to try and do it budget style without compromising quality. (It takes experience to know how to build an affordable and consistently durable engine with used parts). If my engine went kerplunk I'd probably follow a very similar track as you're following now.

Regarding my number of $5k and your current estimate that is under $2.5k:
Most shops doing rebuilds have higher prices on average, and most rebuilds don't end up being as simple as the first estimate. And most times when you pull and engine the owner chooses to change a few other things. So far I think if your rebuild goes according to plan, you'll be well under $5k. But nobody can consistently predict the final cost, and IMHO it's not wise to *expect* that $2150 alone will get you all the way to the finished product.

Thanks Dave for your advise, yes it's true that $2100 its not going to give me the best engine nor it's going to be a finish project. I'm planning to do other things to the car as well and trust me i've been doing to much research and it's driving me crazy to plan every little steps. I don't want to be making or planing as i go, i want to plan it all out before even buying anything. But yes you're right it's like i'm getting what i pay for but i don't really need the best engine out there i just want something that works that's all. Thanks alot :-)

dgeesaman 05-18-07 09:00 AM

Budget rebuilds, done properly, perform just as well and last nearly as long. Buying new housings and such only results in slightly higher compression and extends life a little more, but mostly makes the job of the rebuilder easier. IMHO the issue with doing a rebuild with budget in mind, that more responsibility lies with the rebuilder to inspect thoroughly and reuse parts wisely.

Dave

hanman 05-18-07 09:25 AM

Well, in your $2500 estimate, you don't show anything for R/R of the engine, so can we assume you are doing that? And you have no contingency money, like what if both rotor housings are bad, what about the turbos, wiring harness? etc. etc.
The previous owner of my car just had the engine rebuilt at KDRotary in PA, right before I bought it. They did it right, and it was over 6k. But, even then it included the old turbos.
