What turbo should I ideally get? I'm getting my tax retrun so I might have some money to burn.

zyounker

Actually i voted fort T04E.. but the best (Street) turbo would be a T04 60-1 Turbo.. with a 1.15 A/R.. This is good for ~400RWHP and gets boost ~3-4K depending on exhaust & intake..

Ok i have a good question regarding that 60-1 turbo setup.

Is it worth getting the turbonetics ball bearing option on that?

Does it really spool that much faster?

Is it more likely to break with the bearing setup?

Is there a better option for bearing turbos (and if so, what is the size, i know there is the garrett twin bearing turbos, but i dont know which is equivalent to the 60-1 with 1.15 ar.

I was going to vote for the t04 for best street turbo, but dont know enough to make a good vote yet. Thanks all

No.. i hear the BB option from turbonetics is crap.. Don't waste the money..


If you really want a GOOD BB turbo go for the Apexi RX6...

Geez, a $2,000+ tax return???

I'd take...none of those.

HKS cast manifold $300
And either...
60-1 (boost under 14psi) 350rwhp
T04S04 (boost over 14psi) 400rwhp
T66 500rwhp
T70 600rwhp

Don't forget folks, that to do those higher hp numbers like Ted has posted for the larger compressors, you'll need to run a boost level that is not usually compatible with 93 octane pump gas.

I have the T-66 and I feel that a 60-1 using the same 93 pump gas as me will outrun me, at least in the qtr mile.

The best I have done, with me tuning the T04S04, is 359 rwhp.

The best I have done, with me tuning the T-66, is 376 rwhp but, I lost some in the lower and mid ranges.

PS: I voted for the T04-E

zyounker

If you go with the HKS manifold make sure the turbo & manifold are both diveded or undivided. I would opt for divided.

Oh thats right, i didnt even think of the octane issue. Unfortunately Calilfornia passed a new law that says the highest octane we can buy is 91. Completely stupid, but its how it is. So can i expect to make 330 rwhp with my ported 89 turbo motor, Wolf 3d, more injectors, and a 60-1 1.15ar turbo? Or is 91 not going to be enough octane to run that?

Graham

MikeL

I've never had that combination but, I think you'll make more than 330.

zyounker

It depends on how the motor is ported..

My friend has a very mildly ported 90TII motor with a fairly restrictive exhaust.. he made 370RWHP at 17Psi.. and it was a 60-1 with .96 undivided exhaust.

BTW this was on 93 Octane..

It is hard to buy the higher octane gas sometimes, but a easy, cheap and efficient answer is to buy Toluene and pour it into your tank. It raises your octane by 5-10 points, depending on how much you add. Also, if you ever think you got bad gas at a pump, imediately buy a gallon, 1/2 gallon, whatever, of toluene and pour it in. Much better than octane booster, which only raises the octane by .2 points and costs the same as a container of toluene.

oh yeah, you buy it at a hardware store.

wow lots of good info, where are some good shops to get turbos? I've found a few online but not much to shake a stick at.

just on a side note, i've got a streetported engine with an S-AFC, 680cc secondarys. Do you think I'll still need more fuel? if so I've got to 460cc injectors off a n/a i can put in line somewere

MikeL

Don't get extra injectors and a thing to control them. Skip that and go with a Haltech. Get your 550 primaries rebuilt and buy two 1600's.

zyounker

You can buy 160/lbs an hour injectors.. which happen to be 1680 injectors.. You can find them for ~$100/each new.. But this will require a haltech and a modified fuel rail..

BTW if you are going big single i would definatly take care of fuel!

i'm not going to try and build a race car over night, I'm doing it in stages, right now I want to get the big expence out of the way, the turbo. Once I can decide on that, then I'll go from there.

Does anyone know any good places on the internet to find a turbo for a good price, I've checked the for sale forum on are board and the partstrader when it works.

zyounker

Actually, i would start with cooling, Fuel, and EMS.. Then go for the turbo.. You will need all of those things to do the turbo safely..


-Zach

There's a reason why there's not too many big T04 conversions driving around.&nbsp The turbo necessitates a front-mount intercooler, which adds another grand to the whole conversion (this ignores a lot of the "used" IC installs available).

The T04 conversion is a BIG step.




-Ted

Ridge Tech

ture, but good deals on turbos are hard to find, cooling, fuel and EMS stuff will always be for sale and finding a good deal on them is not as hard, for the most part. Basicly, I have a list of stuff I need, as does everyone, but I don't have a set order to it, whatever I can find first for the best price I'll get. But sense I have this extra cash, I'd like to go a head and get the more $$ things out the way.

zyounker

Well, I would just keep my eye on thepartstrader.. Good turbos pop up on there every once and awhile..


There is a guy on the board that can get 60-1s for ~$700 new.. (i think)


Also check the rx7store.. Not sure on prices for turbos..


-Zach

Ridge Tech

I know what is involved with the converson, but my problem is I dont know which turbo is right for me. I don't care about 1/4mile times, I want something with fairly quick spool and a desent top end for mountain/couse type driving. A turbo that is well suited for quick bursts of speed between coners and has the ability to propell me down the straights as fast as I dare to go. the stock turbo thus far as done this well, but I've moved on and need more, plus with the streetporting, I feel as though the stock turbo is holding the car back from its full poteintal (sp?)

RETed can you tell me some more about the 60-1 you were talking about above?

zyounker

T04 60-1 1.15 A/R is a good turbo.. It boosts ~3K.. And can can put down ~400RWHP@15Psi (Depending on exhaust/intake/porting)

Now you might be better off with a T4/T3 Hybrid.. This would be a T3 Turbo with a T4 compressor.. They usually run ~$600 new. And can push ~350RWHP@15Psi. But this turbo should spool pretty quick..


-Zach

RETed

I recommend that turbo for daily drivers and very mild ported to stock port engines.&nbsp The efficiency of this turbo is under 14psi, so if you keep under 14psi, this makes for a very nice turbo for you.&nbsp The turbo has the potential to crank out 400bhp to the flywheel (people are going to say 400RWHP, but it's at the egde of it's efficiency range over 18psi), which means it's a legit 11-second 1/4-mile car with 0-60mph times in the low 3-second range; I know you mentioned no drag racing, but these numbers are to give you an idea of speed.

After reading your follow-up post, there are very few turbos options that will fit your bill.&nbsp The A'PEXI RX-series kit will work due to it's relatively small turbo size and BB center; the GReddy TD06 kit will work too - both are BIG BUCKS!&nbsp How much cash you got to spend?&nbsp We're talking at least $3k here for a new turbo kit!

I'd like to see proof that this will work on a 13B???
