Yes i do understand that i cant use this turbo. All i was saying before is this turbo is all i have. The cost doesn't bother me, i can handle the price. i just need help with what im going to need. I dont have any quote from a shop yet but im in the prosess of talking to Titan Motorsports and see what they have to offer.

Unlike many of the other car forums full of morons, this forum tries to keep things realistic. Yes, it sounds like people are bashing dreams, but the intent is to inform others about realistic costs, labor, and performance. Therefore, it is not that people on this forum are denying your dreams, it is that you are denying reality.

Now, back to reality, which rotary shop told you that your current turbo setup was good for a pp engine, and what was their cost estimate and performance estimate for building it? What additional modifications to the car did they recommend?

I'm sorry, you're intending to use that turbo on a peripheral port?

In that case, it's orders of magnitude too small.

For a peripheral ported engine, start shopping for stuff with a T6 flange.

I think you need to start with the basics:

1. Almost any turbocharger that comes off another car is too small for a 13B.

2. Any turbocharger changes require a full standalone EMS and a fuel system to support it.

3. If it has "T3" in the name, it's too small. There are a few exceptions, but generally that's the rule.

we live in an age where you can make 500hp on the stock engine, a PP motor should do better than 700.... reliability is out the window, not to mention you'd need like 3 of those turbos.

we're not denying your plan, but to get THAT turbo to run on a STOCK ecu with a PP engine is, well it probably wouldnt even run at all.

THAT turbo on a STOCK engine with a STOCK ecu, would run ok, but you'd be down on power compared to someone who had a better sized turbo.

ive built a few turbo fc's, i betcha the hotside (the important side) of your turbo is smaller than the hotside of the stock one. my friends gt35 is.

There no way in hell i would put the turbo i have on a PPorted engine. lol Even i kno it's way too small. How exactly do i go and find a exhaust manifold that is a T6 and a turbo that is the same. The only T6 i've ever heard of is on the Titan Motorsport Copper Supra dragger. lol

That also what im trying to figure out is what kind of EMS and Fuel system im going to be needing. The car isn't going to be strickly drag only. And i know im going to be getting like .0002mpg lol, but i just dont kno about fuel systems. I guess i can ask TMS of what kind of system i am going to need.

Oh i know it'll do better than 700hp and that is my plan. reliability i could care less about cuz if i did then im getting into the wrong ****. lol

The ECU i will get when ever and whatever kind it may be will most deff not be stock. Not too sure about the hotside size differances though.

I was thinking of a 20b but i would rather just get a 3rd gen. and the fact of kicking a supra's *** with only 2 rotor just sounds bad *** to me, seeing that they have 6 pistons.

Rather than post your newest daily whim on this forum, I think you need to have a long talk with Titan Motorsports so you can at least get a realistic game plan together.

I know it can be a confusing subject seeing that none of us know eachother or where we're coming from.

I serious about this turbo oh Titan doesn't do rx7's.. ****. But i was reading up on this forum with this guy that doing something similar to what i am but he was just wondering what turbo to use. Here is the link the only differance between me and this guy is im ganna be running a full Peripheral port setup and around 40 - 45psi.

https://www.rx7club.com/single-turbo-rx-7s-23/turbo-choice-661820/

Make sure you read the whole thread to understand what i mean.

Set a horsepower goal, then plan your build around that. Dont just chose a Turbo and plan your build around that, its nonesense.

The easiest way to accomplish that would be a 20B, mild port and a GT45. Not an eBay GT45, a real one.

But really, why? What use is an 800HP 2nd gen? You've dumped $50K into the thing and it's wasted by that point.

slightly larger than a street but with a tapered edge to allow for better air intake, and definitely not the same as a bridge

Sorry...Mild port = street port.

I still think your goals are insane. Remember once you've built that $20,000 800HP engine bay, you need a transmission to handle it, some way of getting it to the ground (BIG TIRES), a body kit to cover the tire, some kind of beefy rear end, BRAKES so you don't kill yourself, chassis reinforcement (roll cage), fuel system to support it (big primary tank, surge tank, appropriate pumps and lines), etc. etc. etc.

And then you have an 800HP RX-7 which will kill everyone if you crack the throttle on the street.

God I cant even imagine a 800hp fc on the street, really 400hp is about right for me at least.

Oh i know my car and i can handle way more than 800hp. for the past 6 yrs i've been building a 69 camaro outlaw drag car with my uncle, it's got 1800+hp. last time we dynoed it with a smaller blower pully it was at 1672hp. he has just gotten a little bit bigger pully so we're expecting over 1800hp.

I can handle a 800hp FC. It's just a project of my own.
