Hi everyone I'm new!

I've been bringing in the odd car for myself from Japan for the last two years, and I recently have imported a TD06 turbo skyline GTS which was nice, and also a Toyota Aristo with 2jz-gte, which I am now selling.

Anyway my replacement for the Aristo was going to be a low miles mk3 supra jza70 with 1jz, but I couldn't find any that had decent mods and for a good price.

Anyway I have always loved the look of RX7's and there seemed to be an influx of modified ones recently.

I saw one the other week and decided I had to buy it! I had it inspected and the modification list was quite large and I loved the look of it, so I purchased it (for a fair bit more than I expected!).

I was expecting it to have some kind of single turbo, like a t04 or something as they are popular in japan.

Anyway after seeing the pics, it does have a single turbo, but I haven't a clue what type it is, or the size of it.

Any of you got any idea what model of turbo it is and what sort of power it could be pushing with the right mods.

The car also has apexi PFC / AVCR, dual plate clutch, fmic, other bits of kit, not sure about injectors or porting though as they never go into that much detail.

Anyway here is the pic below!!



Thanks people,

Jon.

 

Im jealous. I wish I could import 7s from Japan here. I would ****** up a bathurst or spirit R in a millisecond.

 

welcome to the forum.

im no expert but it doesnt look like a garret turbo. and its most likely not a greddy turbo since its not labeled all over the place. so im goona take a shot in the dark and say 500r maybe?? cause of the size and shape. rich will call me out if im wrong..

as for the power your putting down to the wheels. with a turbo that size i would guess 300whp-350whp at 10psi and maybe 350whp-400whp at 15psi

 

Cheers matey!

Wow 350 at the wheels would be plenty for me.

is 15psi safe to run? What would be the max, if its all mapped correctly etc?

 

Some more pics...

 

Looks like the apexi Rx6b or whatever it was called that was popular back in teh day. It is an extremely expensive kit if I remember correctly, around $4k or so.

 

Interesting.

Can't find much info on this rx6b as it seems to have been discontinued about 3 or 4 years ago.

Sounds like it is capable of 450whp at a push.

What sort of trap speeds can I expect from a tubby this size?

I'm aiming for 120mph terminal as I lost to a Skyline GTR which did 124 over the line last year when I had my old Skyline GTS, and I vowed to go faster one day!!

Cheers,

Jon.

 

450rwhp will net you about 125-129mph trap speeds for the typical fd.

 

Wow thats insane!

I suppose that is because it is so light! My skyline was a lardy 1450kg and about 360bhp and I got 109.7mph on the trap speed.

Cant wait to get it here, and the great thing is, the RX7 can actually handle well!! unlike my old skyline gts which was setup for drifting with a locked diff, it was lethal!

How do RX7's put the power down in the dry, regarding wheelspin etc?

 

Not to sound like a spoilsport wrt the power estimates...

Please understand that the way people in America judge power through dyno numbers is a bit different from how they are recorded in the UK. The difference is, on average, about 15%. So basically, if an American tells you to expect 400 brake, then you should really think 340, if you hear 450 than you should really think 380. It will help to understand this first so that when you go to have your car mapped you aren't dissapointed with your results (I was initially).

This does not mean that American vehicles are more powerful necessarily, it just means that we use different dyno brands and settings.

Jon, have you registered with FDUK and MRC yet? I hyperlinked their websites in my last sentence in case you hadn't yet.

They are two UK based rotary forums, you'll find a good amount of people on them that are much more "local" to you. RX7 Club is an EXCELLENT source of information, however FDUK and MRC are wonderful suppliments as well ;-)

 

Yeah I know about the power estimates, its do do with dyno dynamics and dynojet isnt it?

Still insane power enough for me, especially in a light weight car.

I will try the other clubs, I registered on Mazda Rotary Club but I can't post because it says it waiting for the administrator to check my account first

Also are RX-7's ever used to drift with, or are they better for track and drag?

Not that I'm a big fan of drifting, my old skyline was setup for drifintg and it was crap for traction

Cheers,

Jon.

 

nice find! gotta replace that AST tho

 

What is an "AST" ?

 

is it an air separator tank? i just googled it, lol.

 

Yup, the different dyno brands used is pretty much the reason for the difference in numbers.

Personally I'm more of a fan of FDUK, not as much traffic as MRC, but not as much ego either.

Yes, RX-7s can be used for drift, however they aren't the easiest to drift with/learn on. This is mainly due to the fact that there is little to no low end torque, and the way the stock sequential system delivers the power. It is doable, but difficult. You need to pulse the rpm's a lot more and pay a good bit more attention to exactly what you're doing. As opposed to something like an R33 or an old tramp-drifter Merc.

FD's are setup for awesome handling and grip. Unless you go out of your way trying to drift (or you just hit a damp roundabout too fast) than you'll notice the handling style is much closer to that of an Elise than a Skyline or Supra.

 

Nice car.

I see it has a stock radiator and stock AST. The ast is the black plastic tank hanging on the rad. For a modified car I recommend you change both. The radiator has already turned green from the coolant getting into the plastic and weakening it. The AST can be eliminated using a kit or you can use an aluminum AST. Then go through and do the other critical maintenance that has probably been overlooked. All new coolant hoses, fuel filter, plugs, coolant, and get the suspension checked out for bad bushings and get it aligned.

If you go for more power focus on tuning, instrumentation (wideband O2 is very good, so is EGT and oil/water temp), and add auxiliary injection.

FDs can make good drag cars, but they are not built for it from the factory. You will need to change the rear suspension and much of the drivetrain to handle that level of shock load and torque. However some guys (especially in Aus and Puerto Rico) are doing excellent stuff on the strip with them.

The FD can also drift, but being turbocharged and rotary the torque band is not optimal. The suspension is highly adjustable which helps getting the suspension setup right. One really important feature of a good drift car IMHO is affordable replacement body parts. The FD loses badly there, since all parts are very expensive.

The FD is really a track car. With the right mods to keep the engine cool you can do impressive things on the track with it. It's also a lot of fun to autocross, but it's not competitive except in the wilder classes like SM2 where the last few national champions (members of this forum in fact) drove one.

 

Thanks for that ^^^

Anyone got any clue as to what the turbo is on it?

So far its an Apexi RX6 but I can't find much info on them?

Cheers,

Jon.

 

Not sure about the Turbo.
Could be a precision SC61... but I like the golden Bling Bling Air filter


And when you have the car...
Donīt listen to anyone who tells you to take that wing off.
This RE-Amemiya wing is Fooking rare and woth itīs wheight in Gold
