what turbo for 700hp
 

whats a fast spooling turbo good for street rx7 aiming for around 600-700 at high boost?

The words, "fast spooling, street and 700hp" don't exactly go together. At least not on a 13B based RX-7. I'd say you would be looking at a GT42 series turbo and higher, but that much power out of such little displacement will certainly give new meaning to turbo lag.

first thing should be what are you using the car for. 6-700hp is no joke in these 2700lbs cars. i dont think there are many people who understand that. everyone wants a big number but a 400whp rx7 is a handful to drive on street tires. also 400whp takes down 600cc bikes no problem.

Let's start with the basics;

1. What mods do you have now? Explain in detail.
2. What are your plans for this car?
3. Have you searched this forum, for the other mods to support your hp goal?
4. What budget have you set aside?
5. Who will be doing all this engine work?
6. What do you consider "high boost"?
7. Time frame in mind? One month, two, three....ect.
8. What fuel would you use?

As you see, this is just the start of things to come.

700s are so last year. 800s are where it's at!

lol what he ^ said. do you want whp or hp at the crank? 700bhp could be achieved by a billet 67mm turbo at high boost but there are many things that go into consideration to achieve that level.

Couldn't have said it better, 400-500whp FD on the street requires your attention.

You will need a 20B if you want to stay rotary and want quick spool-up.

what's the fastest or most powerful car you've ever driven?

The question is: what engine for that turbo?

I kinda wish there was a like button for some of these comments!

A GT5541R will get you what your looking for reliably.

Am using the car for the street and some track time, i need it capable for drifting, track, and atlas 10 sec on the drag strip.

1. am selling the Fd i have now , so i can figure out how to buy a rhd fd from canada or a rhd shell and bring it to south florida where i live, and do these goals to it.
2. I plan to use it for street and also the track and some drifting.
3. yes i have been doing research but i want to know what turbos i should go with (turbo that should get be to do a 9-10 second quarter pass.
4.budget is not yet decided am still waiting for this interested buyer for my fd to come today, am getting around $12,000 for it.
5. well cam from pettit used to do my engine work since his shop in down the street from me but he was getting to expensive , so now am deciding either lopez racing, this guy edwin that has a rotary shop by me or luise from dragon motor sports.
6. high but safe with water injection or something better.
7. 2-4 months is fine

familys 69 camaro 900 hp
chevelle 800hp
and some other american muscle cars
but all my japan cars only had most 350 hp most

o and a 500hp 89 supra

What, no snow-plowing or demolition derbying?

JDMFD777, there is no turbo that will work well for all your goals on the 13b. With a 20b, it would be doable but a lot of work and money would be required.

1) you want 700 hp (fine)
2) good response (not possible with 1)
3) you want to drift (not possible without 2 which 1 won't give you)
4) road race (having condition 1 is a "little" overkill and hard to go fast without condition 2)
5) 10 second ET (you can do that on any turbo if your car is setup right)

whats the best turbo thats responsive that can do 9-10 sec?

whats the best turbo thats responsive that can do 9-10 sec?
and cant i just set it up at 10-12 pounds for street,med boost like 15-17 pounds for drifting and 20+ for drag?

Interesting thread..

ill give you an actual responce. no car can do all 3 perfectly, but if your modest it can be decent at all 3. i would say a garrett gtx35r will do it all. fast enough responce for drifting and street and capable of just clicking into the 10's. if you want 9's your talking a drag only car. its not just the power at that point you will need a laggy turbo period. i have a 6765 bb precision on my car and its as responsive as my cast 35r was but i dont consider that good enough for smooth drifting. honest responce here so if your serious spend the money and by a garrett gtx3582r. im sure a-spec can build you a nice kit so get in contact with him.

edit, didnt see your thread thewird but pretty similar thoughts. i love the seats btw incase i didnt tell you 5 times already.

If you have a bucks a GTX35R P trim would be even better.

We've got several plain GTX35R(s) in stock too btw :icon_tup:
