Hi Guys,

At the moment my FD is pretty much standard, it could have an o ring failure but I haven't got around to doing the proper check to see if it is an o ring failure.
It's got a cat back, induction system and alloy radiator, but I've got plans on buying an ebay PFC soon and maybe some other things after that.

So, I've seen what looks like a good deal and am v tempted but would like some input on what else I might need to make it work or even if it's a good idea or not.

Here is the ad:

This is a rare oppertunity to buy an fd3s mazda rx7 engine that has had the expensive single turbo conversion already done, the turbo is an HKS kit with a garret t4 turbo, HKS cast manifold, HKS external wastgate and downpipe. This package comes complete with the full front mount intercooler kit , samco hoses, fuel presure regulator, HKS plugs, magnecor leads and a fully mapped apexi power fc ecu with commander. The package also has the benifit of having the rats nest removed along with the air-pump and the air-con pump, it also has an under drive pulley kit and the 5 speed manual gearbox. The engine was mapped by haywood rotary engines and it was compression checked with the following results: rear rotor 6.0 bar, 6.6 bar, 6.1 bar front rotor 6.2 bar, 6.3 bar, 6.2 bar the engine ran very well in the car and should produce around 400 bhp i have the invoice of the results i had planned to keep this engine but i have fitted an ls1 to my rx7 and need the money to finnish any questions just ask this comes with everything needed to run including loom and starter etc.

All this can be mine for around $2000 which sounds pretty good as I was going to pay $800 for a 2nd hand PFC and also I want a FMIC.
Do these compression reading sound ok, I'm guessing I would need an uprated fuel pump but not sure which, I'm on a budget so perhaps a Supra fuel pump but don't know if it would work.

The seller says it does have uprated injectors though I don't know which ones, I asked if the motor is ported but haven't had a reply yet.

I'm thinking well, if mine perhaps needs rebuilding that's at least $800 and once back together again I would want a PFC and FMIC, this engine "apparentley" doesn't need a rebuild and comes with the bonus of a single turbo conversion already , the turbo is a GT40R which I've read is pretty good.

I will really appreciate any advice you guys can give, thanks for your time.

Sounds like a pretty good deal to me. I dont know anything really about the compression test but for all that hardware for that price doesnt seem like to shabby of a deal.

I hear a lot of people just using the supra pumps for anything under 600hp it seems so you should be fine with that.

Good luck though

Thanks for leaving your opinion, the more the better.

The guy isn't very descriptive, I asked if it was ported, he replied yes but didn't say which porting has been done on it, the apex seals/o rings are standard which I think seems a bit odd, if it's been dismantled to be ported/tuned, surely it would have had uprated apex seals/o rings installed???

I also found out that the compression readings were done a long time ago so they shouldn't really be advertised should they....does anybody know if it's possible to do a compression test whilst the engine is outside of the car?

It seems a bit like a trickster selling a broke engine but he does say that it was running fine before it was taken out of the car......I keep getting tempted by all of the goodies that it comes with...mmmm single turbo, PFC, FMIC....

Edit--- gt40r wow that's a big boy for 400hp. IMO supra pump and gt40r are at the opposite ends of the single turbo spectrum. By the time you get to a sweet spot with the turbo, you have fuel concerns.

You know you can't buy all that for 2k separately. So yes a good deal. Too good to be true? Idk. Single turbo cars sell for less than their parts combined. So it's possible. Although the seller seems detailed enough that they could sell the used turbo kit for that alone. Hmm. Concerned.

Pics? Reputation of seller?

thanks for the reply, well the FD scene in the UK is non-existant compared to in the US so perhaps it's chheaper due to lack of customers??

I have the same question running plus pics in the 3rd gen specific forum, the thread title is " Tempted yay or nay?"

Take a look pls everybody, I could do with as much advice as poss.

Thanks

A bar is equal to 14.7psi so 6 bars would equal to 88.2psi and 6.6 bars being equal to 97.02psi.

Someone please correct me if I am wrong

CharlieUK

don't quite understand how that is relevant to this thread?

Ah yes now I see, sorry, can't help you, most of the stuff over here is done in bar's....I prefer psi myself.

Scarcity normally increases the price. But I'll gladly help watch your back. Ur smart for asking questions. Most people ignore it, because it's too good to be true and they don't want to admit it.

1 bar = 14.5038 psi

1 atmosphere at sea level is 14.696 Psi (what you are referring to)

well if thats the case, then you might look into a rebuild before putting it in your car. The whole deal is not bad at all if you think about it. All those part alone with a motor would normally run anyone about 4k+ easily including labor. If you can do it yourself, then you can save alot.

You should ask the seller alot more questions about the condition of the turbo. If you can get pics that would be a plus also. I hope some more experienced users on here can give some helpful advice on your situation.

Ha!! The guy obviously got spooked by all of the questions and told me that he sold it to somebody else!! a guy in the US.

Another forum member told me that he saw this engine on ebay a while ago, probably its busted and he's selling it on as a good working engine, I just hate those lying scumbag tricksters!! Karma will bite him in the *** someday

Just shows it always pays to air on the side of caution.
Thanks for the advice guys, I appreciate your time.
