Educate me on TE45A...

[coach]

Hi Guys,
I was at BPG this weekend and when discussing my goals with a few of the guys, I kept hearing TE45A as a turbo I should look at. I want a turnkey 11 flat car, with mid 10 potential.Is this the turbo for me? Is that possible? I mostly street drive, but after this weekend I will def make it to the track a few times over a summer. Read my sig for my other mods, but stretched IC and 60#'s are coming with the turbo.

Thanks,
Coach

i think a TE45A is a PTrim 66 in an E Cover..... and YES with proper tune and parts you shouldnt have a problem. HTH

to make it A LOT easier you would probably need heads and a TC

 

[coach]

Should have said that in my first. Heads are coming, but I am pulling my 18000 mile engine and starting from a girdled 109 and Champion irons. This purchase is planned for the spring, but I do my homework well in advance.

Thanks
Coach

The TE45A is a great turbo. I went 10.60s with it. But from experience the PT67 makes more power with less converter.

 

[coach]

Don't need more power than that. 10.60's and I would crap my own pants.

Thanks

The TE45a is obsolete, the new PTE 62/62 is the new improved 67 P trim, spools faster and makes more power throughout the band with a touch more power at the very top.

Since you haven't already bought this turbo I'd only get the 45a if it was used and a great deal.

Coach - i would agree with this statement... TE45a is ol' skool... there are a lot of newer turbos that WILL get the job done and are reasonably priced:wink:

Or see if Cotton's can get you a Tnetics T66BB. He had a good sale on them a while back.

Well... I guess I'm gonna go against the grain here, because IMHO you're wrong!! I've run the Te45a on a car here and there since back in '99 at the Buicks @ Bristol event, well before most even knew about the turbo. Just because its been available for time well tested, doesn't make it obsolete. Newer isn't always better. The Te45a is what the fastest TSS cars currently run, but with a Q-trim exhaust wheel. These cars run 10-teens at almost 140mph, full weight street cars.

When I look at turbos, which options do I want? I do not know what the .63 and the S-cover , etc really mean. What difference is there in a 4in-2.5 out versus a 3in-2out ? I am asking so I have knowledge for future reference. I cannot stand being at a cruise in and someone askes me about my car and I tell them um,oh,well,let me get back to ya...LOL I laugh at kids for that crap and now I find myself doing it.

Thanks

+1, it's a well proven turbo...old school or not it still kicks ass to this day. I bet you can find one for a great price since it seems everyone is ditching their "old tech" turbos for the new BB units.

 

[coach]

Can it still be bought new?

Thanks
Coach

TE45a is a good turbo, but it's not as powerful or spools as fast as the BB62/65.
It might be good, but not as good is my point and hence is obsolete if you're considering buying it new. Why would you buy a less powerful and slower spooling turbo for about the same price?

You know the 62/65 is a billet compressor wheel and the newest exhaust wheel technology?? Then slap on the BB and it's a no brainer, more powerful and spools faster.

The Q trim in journal form is not a street turbo imo and totally changes the characteristics of the 76 trim turbo he's talking about in the original post. Need a 3800 stall to have it ok at the strip. Yes 3800 at zero boost/vacuum. 4000 would be better. The 76 trim version will work on a 3200. The 6765 will outperform the 45a in all areas. So in reality it is a dinosaur. Didnt say it wouldnt work. Because they have been mid 130's but there are just way better options out there now. Less stall required and more hp potential. This is all assuming the car will be run a little harder in the 24-26 psi range. If you plan on running low boost you are fooling yourself if you think there is any real world gains over one another. Keep in mind the TE44 has been 10.80's on unported iron heads . Most dont even come close to maximizing the potential of their turbos so they dont really see the added benefits of the newer tech vs. the old tech.

ALMOST!!!
I have one i would sell. It has been on the car a couple of yrs. , but has prolly less than 750 miles on it. Comp. housing has been ceramic coated.
Turbo looks fantastic and has zero shaft play. I have had no issues whatsoever out of the turbo.
I have been 11.38@124 on drag radials--the only reason the car wasn't in the tens was my 60'

I would take $600 for it if you are interested.

Proof?? Other than what a vendor states??

The cars I'm talking about only run a "0"-pump multidisc. Not even close to needing a 4k stall. And yes... They are 100% street cars.

Let me know when a car with the 6765 outperforms the Te45a. I haven't seen it yet, and from the looks at all the posts people are making with questions about the performance of the 6765, no one else has either. Again, lets not base the information from what a vendor lists to help sell the item.

Is it too much turbo to run with just an IC and Injector swap? I will also change converter. My sig has other mods. I would tune it back until I swap out my numbers matching engine. I do not want to hurt my OEM block. I have come across another 109 that I will girdle and roller with Champion irons. Then I will crank it up, but until then high 11's will be all I will push out of it. Once the new motor is done,10.90 to 10.70's will be my goal.

Thanks

It will be very laggy with a stock TC. My 63(TE45) was pretty laggy with the stock TC. The 45A is slightly bigger than the old 63/TE45. I'd consider checking out the Tnetics 66BB. Cotton's had a good sale on them. They were priced about the same as a journal bearing turbo. Should make the same power as the TE45a but spool faster.

I am swapping over to a 66B from my old 63. I was happy with the 63, but it smokes occassionly. So I got a new 66B instead of fixing the 63. I was very happy with the 63 though. I will post up results once I run the 66. I am getting the exahust housing coated right now. So it should be on the car in 2-3 weeks.

But I do agree with NCTURBOS, the old school turbos still work great. I run better times with my old school 63E than my buddies car with a 6765 DBB on 2 lbs less boost. Both cars have the same mods and weigh the same. I run on DR, he is on slicks, I run 93 + alky and he is on 116. :biggrin:

+1 for T45a

old school??
hmmmmm, over 600 rear wheel horse power, 11.00@ 130
more responsive that any of my other turbo buicks,
3500 stall converter, will melt the tires off of it on the street.
I Love it!
it s up to you, but I'd never be afraid of it.
