looking for comparisons still havent bought my new 13b yet but Im lookin to get a loan an if I can get a good engine to build up (400hp) Im ok w/ jus having one turbo but I need pro's an cons


cuz BOV's are sexy...

 

13bt is only 1 turbo, turbo 2 means 2en turboed rx7 not twin turbo. just get a 13bt. i almost bot a 13b and way going to turbo it but was convinced not to so i got a GXL with everything tII on it from motor to mirrors

 

Um, what?

First, check the FAQ for common questions and answers. Then, read the Archives. After that, do a search for "400 HP".

You're going to get a loan to pay for things? Bad idea....400HP will cost you $5000 or more when all is said and done...

 

well I din mean righ off the bat I wanted 400 I jus want somethin tha will be able to get up tha high.

 

Aaron cake what do you mean 5000 dollars are you stupid or something you dont even have to spend that much

 

Stupid...no,

making an estimate at a reliable 400hp...yes.

 

1986-1988 2nd gen rx7 was just called Turbo or series 4 S4 but on the 1989-1992 it was called the turbo 2 or series 5 s5. On the s4 it had 182 hp and on the s5 its had 205 stock

 

hahah he tried to make fun of aaron, strupid yes, should of said it no

 

You are one dumb son of a bitch. Then why did my 1987 Mazda RX-7 "Turbo" have a Factory Installed TURBOII sticker on the front fenders??? And for your information Arron knows more about RX-7's than you've ever read about them.

^^^^^+1!!

 

this forum blows

 

Jesus, dude....

First of all, there was no 1986 Turbo Rotary. This was not until 1987, when the turbo was introduced...

Second, you are ***-backwards. 1987-1988 turbocharged RX-7's were called RX7 Turbo II. Mazda caught the difference, noteing that there was no turbo before this one (Japan had a turbo first gen.), and changed it for the 1989-1991 to just the "RX-7 Turbo."




What the hell was the line about blow off valve's about?!

 

To the original poster, don't put yourself in debt over making your car go fast. It really isn't worth it.

And to whoever called Aaron Cake stupid, you've got a learn to learn man. He's one of the smartest people on the board, and he's got a wealth of information he's continuously sharing with everyone.

 

I have a build receipt in my possession for > 12,000 dollars and a dyno sheet for 409rwhp (albeit before the Steve Kan tune) and in the past two weeks I've broken an oil cooler line, and now something is wrong with my 4-puck.

... and my engine has ~3000 miles on it.

If you want 400 horsepower, you'd better be ready to nickel and dime yourself on a consistent basis AFTER the initial build, in which you will pay a great load for all the parts you'll need (for 400 horsepower, chances are whoever builds it is going to strongly recommend porting... it'd be tough to get those numbers without a port of some sort anyway)... that includes computer, fuel system (injectors, fuel pump, FPR, etc), turbo upgrade (turbo itself, wastegate, bov, intercooler, manifold, downpipe, etc), and necessary reliability mods like fixing ANY pre-existing electrical problems, upgrading ignition, and of course you'll want fatter tires, and fatter tires means new rims, and new rims mean you'll probably want to go ahead and roll the fenders, just in case... and of course, you'll want to upgrade the suspension with fatter tires.. don't want to bust any axles.. do you see my point?

you're not going to get away with 400 horsepower SOUNDLY (unless you're planning on doing all the work yourself, in which case you could save a bunch on labor) without breaking 10k... even if you don't do everything at once, once it's all said and done you'll be above that for sure.

FC3snick04, I don't know what kind of 400 horsepower you're talking about.. I'm not talking the kind that sits in your garage for 350 days a year... and I'm guessing Rush02 isn't either. Care to elaborate on how you can get 400 horsepower with 5,000 dollars? I'm curious to hear.

 

You can get 400hp for 5g's easy . . but that's just 400hp not the rest of the **** that Peachy was talking about. Megasquirt plug and play- 550, widband- 350, 4x1000cc injectors- 350ish, turbo-600, manifold-350, wastegate-100, exhaust- 500, intercooler-500, fuel pump- 200. That's only 3400 right there and would be able to make 400+ with out an issue. This would be for someone like me who would do all of there own work. That still leaves 1500+ for extra's like gauges and gaskets and all the inevitable little things that will have to be replaced.

 

check this link every stock rx7 and rotary setup.

Little things like an engine because you didn't upgrade the radiator and fan. That big turbo and mani puts off a lot of heat. And if you can find that kind of a deal on a turbo that makes that power, you better get it quick.

 

I knew I was forgeting something. Ok, radiator-250. . stock fan is best that still leaves alot of left over for bigger turbo and ****. The BNR stage 4 is capable of 400+ hp and can be had for what like 800? It has been proven at over 400rwhp. .

 

See, that's what I mean.. there are things in there that need, or will need, to be bought that haven't been addressed. When I think 400 hp the -right- way, here's what I think:

Necessary engine work (port, 3mm seals, gaskets, etc) - ~2000
Haltech E6K/E8 or Microtech LT8S or something - ~1500 + 500 tune
500hp Fuel Pump (150) + 2x720cc(250) + 2x1600cc injectors (250) + FPR (200) - ~ 850
GOOD, brand-name turbo - ~1400
Waste gate + Manifold + BOV + Welding - ~1000
Downpipe - ~200
Whatever you want inbetween DP and catback - ~100-300
Catback - ~500
FMIC - ~1100
Radiator + fan - ~500
Clutch + flywheel - ~600
Vacuum hose upgrades / stainless steel lines - ~400
Ignition - ~300
ALL guages - ~500
Rims/Tires/Necessary Suspension mods (gotta have a way to transfer 400 horsepower to the ground) - ~3000

That's > 12k right there.. granted, I went a bit steep on some things, but I also didn't include labor (supposing the work would be done by someone else)...

 

Just Turbo (not T2) were turbo FBs. T2 was the FC.

 

I think we're done here.
