if i want to produce 400rwhp safely.. and have the quickest spool as possible which would eb the better choice and why?

a-specs 500 turbo kit, or apexi's rx6 turbo kit? can both do 400hp at the wheels on a 3rd gen? and which has the best streetability as for spool up etc??

GT35R is perfect for what you want.

I started a similar discussion on the 3rd gen section:

https://www.rx7club.com/3rd-generation-specific-1993-2002-16/what-mods-my-new-power-goal-yes-ive-searched-read-735375/

Between the turbos you're listing the rx6 would be better suited, but they seem to be very pricey. I like the sound of the RX6 from other reviews, but leaning toward gt35r .86 A/R. I assume they produce more of them and that is one explanation for the $1400 cheaper kit price.

I'm also thinking about keeping a smaller I/C and going Alchy Injection. This will help spool/response. This also helps acheive your goal of "safely" producing the power you want. Consider AI.

the gt35r turbo sounds good by me with the .86 a/r, however can it produce full boost at 3500rpm?

also as for my intercooler I have a fairly large front mount so it should be able to cool about anything for what im looking for.. I want my car to be able to do this while running just 93 octane.

the core of my IC is 11" tall, 27" wide and its 3.5" thick. so as you can see its not a super small one.. it should be able to cool down the charge temps of most turbos at decent boost levels.

Probably pretty close. Definitely full boost by 4k. keep in mind that even at partial boost, it is pushing way more air than stockers. I think if you want 400hp the GT35r .86a/r will be the best match as far as getting you there and still keeping as much spool-up as possible.

Others may suggest BNRs at a higher boost level, but I think 400whp is maxxed out. But it sounds like you're looking at singles anyway.

That FMIC will be adequate.

Edit: the guy who had the .86 a/r said "had full boost by 3700"

ohh im not sure if it matters any also but i have an agressive streetported motor.

**** all that Garrett bullshit
get a turbonetics GTK series turbo
they have warranties, so if you throw an apex seal into your engine (expect it one day..) you get that fixed for free
and that turbo will spool quicker than any other turbo of equal size. i bet it

why would they waranty my motor cause i use there turbo?

Turbonetics is definitely a no go for me, not being biased either I have ran tons of them here and they all have failed or fallen apart. Must be user error I wont even get into the issues we've dealt with on trying to get them to replace stuff. Maybe we just ran too much boost through them

I can't grasp why you guys are stuck on running these BB units with these tiny exhaust housings run a 1.0 divided T4 35R you will have 15psi anywhere from 3300-3600rpm depending on setup. That is 7psi by 2800rpm as well. Needing more boost then that sooner only gives you more wheel spin sooner, nine times out of ten(ie depending on what gear your in) . With that housing you also wont be choking up top either. 400whp will be easy fun and give you room to grow when your bored.

Ask Goodfellas if he is unhappy with his response.

No warranty on any turbo would cover damage caused by a blown engine.

I have no doubt someone's passed off some type of damage to be faulty manufacturing and had something fixed for free that shouldn't have been, but no one will fix your turbo for free because your engine blew, period.

And why would the turbonetics turbo out perform anything of similar size? Or more importantly, how could it?

I've heard a lot of good things from the forum members about the GT35R garrett turbo. It's what I'm going with when I to upgrade from Twin to single once I get an FD

rollingsband1

isnt goodfella running the 500r kit?

Yes he is, bigger turbo and all and I bet he will tell you he still thinks his response is very nice. And that is him switching over from BNR twins.

Thanks Sean. I was hoping someone with your depth of turbo knowledge and experience would comment on the A/R choice.

1.00 it is, haha.

I'm pretty sure he is spouting nonsense in an attempt to get people to go to the link in his sig..

I have the RX6 and I am very happy with it. It is pricy, but mine came with the car.

zenofspeed

All things being equal, I 'd probably get an RX6 just because everyone who has one raves about it. And I like Apex stuff, lol. But all things aren't equal as the kit is almost $1.5k more.

I think you need to leave yourself a little room to grow. Horsepower is pretty addictive. I bet there are a lot more people who wish they would have gone with a larger turbo than people wishing they would have gone with a smaller turbo. One of the best ways to save money when modding is do it right the first time.

I made that mistake on my MR2. I ended up spending something like $13k over 18 months only to IMMEDIATELY part it out and buy an FD because I wasn't satisfied with the power.

Chaotic_FC

well, this is by word of mouth, but i know people who have had apex seals shatter there turbine wheels and get it all replaced for free.

and its because its a dual ceramic ball bearing turbo
compared to a regular turbo, i forget the exact number, but its somewhere along the lines of 30% better spool time.. at least thats what i read somewhere

classicauto

Perhaps but that'd be an exception to the rule.

Garrett has ball bearing turbo's as well, the GT35R being one of them.......

I have driven and ridden in various FDs from stock to Rotary Performance's Single Turbo Drag car. By far the best setup I have felt was the RX6 and was one reason I bought the car that I did as I wanted an FD with that turbo.

Yes, for a dedicated drag car, pull the turbo off a Caterpillar bulldozer and knock your self out. My streetported motor/RX6/Power FC combo is a very nice setup for street/strip/track. Yes, you can probably make more power cheaper, how how easy is that power to modulate and what kind of lag do you have? Everyone has their favorites, but I don't think you can say there is a "right" way to do it. That would be like saying all FDs should be black. It is a matter of taste, feel, and what works for you.
