Im aiming for 400-450ish whp with my FC.Would this be the best size turbo for me or should I go with a T04 of somekind?

I've seen a similar size turbo make 470 at less than 20 psi, so this may be too large for what you are shooting right. This was on race gas however.

It depends of the cfm flow of the turbo..the trim, a/r, all that stuff. and remember the hp numbers given to that turbo are what they can support. that don't mean your going to make that much power. My T04E is rated to support 475 hp..but I'm only looking for 400 shaft hp.

470whp is not to large for my goal like 495-500 is.

Do you want 400-450 or 500?

just about anything under 500

Look into turbonetics To4e B.B. turbos you can get one that will support that with no problem. just ask for the T04e 60-1 , Q trim. you'll be in the range you want.

Then you will have to determine how much lag you are willing to deal with and what kind of powerband you want. Remember, a t66 is about the same size as a greddy t78.

How are they about the same size...im thinking of a 50 shot for lagg.

Greddy uses a retarded sizing system.

Nitrous won't spool the turbo. With the nitrous, you will still have lag... you will just have a substitute for the loss in power while in low RPMs while the turbo is waking up.



Have you thought about the "rest" of the car? I really wouldn't start with picking a turbo that makes 450-500... I'd start with making sure the car can accomodate that kind of power.

T66 can make uber power with a bridge 550rwhp+

Remember, a nitrous shot creates a big jump in the amount of exhaust gases being created by the engine. In won't lower the boost threshold a whole lot, and only while the button is pushed. But, it'll overcome any inertia related lag real quick, as well as making the turbo spool a whole lot faster in general.



Its kind of a mix of both. https://www.nopistons.com/forums/pub...IR#>/smile.png

Good point. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Damn then a T04 of somekind is what I should be looking for.

TO4B or E would work.

ive desided to go to a bigger whp range and go with the T66

Have you planned the mods to support such upgrades? Not exactly a bolt on..

Im going with the HKS T04E kit. It can put out 400RWHP at 13psi and if you rilly need be it can dish out 500+rwhp but if you try that to much expect to see little pits of your car shooting through the hood:)



Good luck

no im planning that at the moment...any suggestions?

Yea, I'd suggest a FAT bank account.



That way your can buy the computer, injectors, 1-2 fuel pumps, fuel lines, nice 3 row IC w/pipes, upgraded bov, full exhaust, custom dp, radiator, boost gauge, egt gauge, wideband, ignition system or at least a MSD6a on a TII leading coil. Your going to need a new engine, clutch, diff, axles.



I'm sure I forgot some small things but so far all that adds up to around $12K then you can add in your turbo along with the manifold, good WG, and professional tuning and that should bump it up to around $15K or so.



Let us know how it turn outs, you should be able to run some low 10's

He has the cash i'm pretty sure. Last time I checked he had 20 grand saved up for an FD.

Those #s are little high for a to4E. I've never ever seen more than 400rwhp out of a to4E.

Depends on you wheel and housing combination.I have heard of people getting as much as 425whp at 15psi. https://www.nopistons.com/forums/pub...#>/biggrin.png Mine better crank out 400whp when its running or else. https://www.nopistons.com/forums/pub...1047683358.gif

I have the HKS T-04E. I have 320RWHP @ 1 Bar with only 2 hours of tuning on a stock port 13B-REW.



It is getting street ported as we speak and we are going to spend a lot more time on the dyno this time.



400RWHP? Attainable, I have been told I will see a 15% increase in power w/ a street port. If I get all my bugs worked out and it tuned real nice I am expecting to see very high 300's to the wheels.



I love this turbo it spools really fast and the power is very linear.



This is a dyno sheet from my last pull in 90° weather. Notice how the HP ramps up and stays there. It makes the car very drivable on open track and Autocross.

Good luck!!!

I believe a 60-1 wheel is the biggest you can fit in the to4E housing, correct?

https://www.nopistons.com/forums/pub...1047683785.gif Yeah I know its going to cost a nice dollar and I don't have much money for it at the moment but I keep saving up. https://www.nopistons.com/forums/pub..._DIR#>/sad.png This will not happen overnight or in a month.It's probly going to take me a year or 2 untill the project will be all finished.

you can fit a 66 wheel on T-O4e. i have a T-04e with a 66 wheel and 1.32 rear exhaust.



i currrently have dynoed a 479 rwhp @ 26 psi but i blew a side seal in the process.... oops bit of bad luck but good as now it will nice and fresh.

HOLY ****!!! Post more pics of that badass 1st gen Sharky!!!!

yeah nice FB ya got there...got some engine pics as well

26PSI https://www.nopistons.com/forums/pub...IR#>/blink.png WOW!





I'll stay at 1 bar thank you very much. I already saw what 30 PSI does to a rotary and I dont want to make that expensive mistake again.

lol thats half the fun of it..........



mine cops a hard time when im racing but i like to put put around too !



all my car shots are at my site..... www.eziracing.com

Nice FB.The company I bought my E from said that the wheel is a .70 with a 1.32 housing on it.I hope to run 20 psi on mine by fall.Or pop a apex seal trying. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

https://www.nopistons.com/forums/pub...IR#>/blink.png https://www.nopistons.com/forums/pub...DIR#>/ohmy.png That is a ungodly Fb you have.Nice specs. https://www.nopistons.com/forums/pub...DIR#>/cool.png

Hey sharky, I've seen quite a few of the turbo dealers in Oz selling the same exact turbo. They all say the same thing:



i.e turbonetics T66 compressor wheel in bored 0.7 T04E housing

P trim exhaust wheel with 1.32 housing



What I've been curious about is whether they use a standard sized shaft like normal T04Bs and T04Es or the large shaft that all the Turbonetics T series turbos use.



I always would have thought that a 1.32 would have given a lag monster, but a friend of mine has one of these and it isn't too bad at all. I'm so impressed that I'm on the verge of ditching my setup and going to one of these turbos.

i do use the larger shaft and a 360 degree thrust bearing which i would recommend. i do say it is very laggy now but thats the way i like it as it has like no power and all of a sudden LOOK OUT !



boost comes on at about 4,800 and runs right thru to 9,500 comfortable. rev limit is 9,700



this is why i have bought a full manual C auto with a dominator 5000 stall plus transbrake. my aim is for a 9 sec pass and ill retire her from the track.



i have a eboost which i set for moderate cruising at 9 psi if im a scab for the week or when i race its usually 22 psi up to 26. the engine was built for 30 psi but im not that game. its a handfull now lol https://www.nopistons.com/forums/pub...1047683329.gif

I love your car Sharky. Nice job.

Well i lied,



The kit im going with is the HKS T04E kit but with an HKS T04R or T51-R turbo. T04R 450hp @15psi,T51-R 475 @15psi, push to 26psi or so and you could hit 500rwhp.



https://www.nopistons.com/forums/pub...IR#>/smile.png Sorry for the misleading info. But i have seen a T04E put 400+rwhp down. Fully tuned, sgressive street port, and many other bolt ons.



Good luck
