What would be a good turbo for 400 - 450WHP for the FC w/ a street port running no more than 20PSI and pump gas (93 is highest around here), 15PSI for street 20PSI for track. Something that is pretty streetable and is able to spool rather fast and make that power.

Any suggestions? TO4E, TO4R? T66BB.... Any ball bearing turbos?

Thanks.

 

Most streetable would probably be the GT35/40..


But the TSO4 and T78 would also do it..


go with the big GT35/40 (1.06 A/R)

Or with the others ~1.15 A/R.

We happen to have a kit for the FC already made for the 35/40. We actually just finished a kit for a RX2, running a S-5 motor.

 

I would suggest the GT35/40 as well. The Apex'i RX6 would be another good option.

 

Thanks for the replies.

A-spec Tuning, how much is the kit? I assume its ball bearing (GT).....whats the spool like? and what does the kit come with?

thanks.

 

I did nearly 400 hp with an ported motor on a T04E with .70 a/r 60-1 1.15 a/r p trim exhaust side at 17 psi, the turbo isn't even in the efficiency curve till 20 psi plus, with a ported motor and that turbo it should make 450 easily...Max

 

Thanks for the tip Max. What kind of gas were you using? What is the spool like?

EDIT: Maximum amount of octane around here is 94 not 93. So 94 octane and I guess 15PSI for normal street driving and 22-23PSI for track.

 

I have a ported motor running a T60-1 w/ .70 compressor housing and 1.00 A/R turbine @ 15-20psi on 93 octane fuel and mines right about that level of rwhp too.... The T04E/T60-1 family turbos are really pretty inexpensive too. I'm not saying anything bad about the other turbo's listed because they all rock, but the T04/T60-1 is a great all around high HP turbo.....Just my opinion...

My favorite turbo is still the T66, but finding a manifold that will last was my problem....

Yeah I agree Brad, there are some pretty wizzy turbo's out there , but when it comes down to it, the old garrett t-series is hard to beat, cheap to buy, cheap to rebuild, and lots different wheels and trims available if you wanna play...
I just had my Turbo rebuilt, I am thinking now of getting the t-66 compressor wheel fitted to it, according to the turbo shop it should make my t04e into a killer street turbo, which its kinda is already...

Junkie: The spool is pretty good , even on a stock port sickly series 4 motor, now with my S5 the spool is not that far off stock TII spool, but it pulls like a freight train to 8500 rpm once the tires hook, which is somewhere in 4th gear....The octane has really taken a dive here, all we can get now is 91 octane here, and I did the dyno on 91, I am going to buy a drum of 94 next time I go to B.C. I think, Alberta gas sucks....Max

 

Yes I've been looking at TO4E/60-1, and I'd have to agree with you guys on the valve compared to other turbos. Good response, inexpensive like you guys mentioned and a great street turbo. And www.cheapturbo.com had very good prices. At first I considered a T-66BB then I seen the price. Then to GT35/40 Kit, sounds like a very nice fast spooling excellent street turbo but again the price.....the 3rd gen kit is $3999, that roughly translates to slightly over $6,000 CND, WAY too much, when a shop about 1 hour from me could do a custom turbo kit w/ everything curcial and essantial for a turbo kit/upgrade for that price(turbo, manifold, fuel mods etc.)

Whats a step up of the TO4E? TO4R, correct? how much better is this turbo or TO4S?....especailly for the street. And The boost levels I've listed.

bkapold@aol.com: You said you had a hard time finding a manifold for the T-66 that would last, why is that?

Max: Nice, so T-66 compressor, 60-1 exhaust side? sounds sweet. How will it fit?

-20B Junkie

 

check the mods in my sig how much boost could i run with 720cc secondaries and a s-afc?
It's a Garret T04 it says 60-1 on the turbo

 

Max,

What about the T-66 compressor wheel is going to improve your current setup?

Quicker spool-up?

I'm not that well versed in all these different turbos:

 

I have the T04B 60-1 .96A/R .70trim with 4inch inlet.

Hopefully this was a good decision. I wouldn't call $88- cheap though..

cheapturbo has very good prices. I bought mine from Turbonetics.

Evil, The t66 wheel according to the turbo shops math, and the charts, should flow about 75 hp worth more air at the same boost levels, and with the turbo moving a bit more air, with the same exhaust side, in theory should spool quicker than it does now, and have more punch sooner... They suggest jumping up an exhaust housing size if I wanted to go bigger than t66, like 1.32 a/r.. Air in + fuel means alot more gases have to get out...

Nota944: got your Pm, thought I would post the response here for everyones benefit.. Basically the t-66 upgrade requires the compressor wheel and remachining of the front housing to accomodate the different profile. A local turbo shop that does really good work, quoted me 400.00 Canadian to do the work, I am probably going to have it done before summer... Max

 

The kit includes manifold, downpipe, gaskets, oil and waterlines, neccesary blockoff plates, hardware and fittings and of course the turbo.repsonse is really good you should see postive boost around 22-2300rpm 7lbs by 25-2600rpm 10lbs by 28-2900rpmand 15lbs around 33-3400, this may vary a little depending on a couple of things, but not much. depending on porting and whatnot at 15lbs you should be around 430-440whp. the turbo is eff. up to 29lbs.

Hope that helps Sean

 

I am very interested in a GT3045 kit for the FC, though you didn't answer the most imported question 20B junkie asked. How much

Daniel

 

how much money would it take to make a turbo II hit high 12's?

 

Sorry, the kit would be priced at $3299.

Thanks,sean

 

Thanks for the response A-Spec tuning.

Abit cheaper than the FD kit, $1000 CND cheaper, lol. $5,015 CND for the kit though. Its probably worth it, I've heard no complaints by anyone with this turbo.

 

Does this locate the turbo "up high" or "down low"?

What type of metal are you fabbing the DP and manifold from? Stainless or mild steel perhaps.

I believe I've read somewhere that you are using a 46mm WG, could you share the brand?

Could the ACV be fitted yearly for a visual inspection pass? I won't need it all the time, only for the yearly visual.

I assume the manifold and DP are uncoated in anyway, but perhaps could be for extra $$$'s?

lastly, does anyone have a pic of this kit installed on a FC?

Thanks

 

What about a TO4S or TO4R on the street running 20-23psi?

 

The manifold when done low mount could retain the ACV and is done with heavy gauge mild steel.
If you wanted, a high mount manifold like the FD it could be done, in either mild or stainless, same with DP, wastgate were 45mm but we've begun switching to progates, they are V-band and are a much nicer unit but they will increase the price a little. We do offer coatings on whatever you want.
I will see if I can find some pics I used to have.
