This was a staple turbo for the TR for years, many a cars have made high-mid 10 second passes with this turbo on a good tune with pump gas and meth. The TA-49 is a stock appearing turbo which was one of the first aftermarket upgrades available for these cars (all the guys who had cars in the late 80's remember). I believe there have been some TA-49's to make it into the 10's, that is with considerable engine work, ported heads/intake, cam, ect. I'm not a turbo guy, maybe Bison or someone who is more knowledgable can chime in, the information above is just from memory of time with the TR car crowd and surfing this forum for a few days now....

Also suggest you ask the mods to move to turbo forum, may do better on replies

Have a PT61 on my '86 that it came with, or I think its a PT61... interested in thread results as its likely close to the PT60 in specs.

Could be a Te-60? .. don't remember their being a pt60.. their was a Pt-61 tho.

Digging up old info going to put it here so it can be added to;

a TE61 uses the same wheels at a PTE54, a 60-1 compressor wheel and a 69 trim turbine. The TE62 uses the 60-1 compressor with a P trim (76 trim) turbine so it's a step bigger than the 54/61. You can also go with the new GT67 compressor wheel and your choice of turbines, in a small shaft format
new "PT61" (not the old TE61) is basically equivalent to a TE62, as it uses the same 76 P trim turbine and the new 61mm GT compressor wheel. Basically it is a TE62 with a more efficient compressor wheel. It should not have any problems going high 10's with ported heads and a cam.
PTE will build a PT61 turbo with your choice of turbines, GT350 (forget the trim but the same as a PTE52) or 69 trim (TE61/PTE54) or 76 P trim (TE62), depending on your feelings about spoolup vs. max power, so I really don't think you can simply say a PT61 is closest to a TE62 because it may not be. Just think of the PT61 version with each different turbine as a step up from the old style models that used the same turbine.

I disagree with that info. The old ta49 and ta60 use stage 3 t31 turbines and will spool with a lot less stall at 0 than a 76 or 69 trim t04 turbine even though the compressors are very close or the same in the case of the 60 and pt54. They are so different in flow compared to the stage 3 that they shouldn't even be listed next to each other. Ta60 with Garrett .63 will spool decent with a 12" 2200 stall converter and really crank with a 10" 2200. The t04 76 and 69 need at least 600 more stall at 0 with a 10" to have similar response with a Garrett .63. With bigger ex housings even more stall is needed to get them responsive. Stage 3 turbine is for a stock headed engine with a cheap converter. The t0476 and 69 are for 10 sec power and need a decent converter to work properly. 60-1 with a t0469 or 76 will go to 600hp on a v6. The 60-1 with stage 3 will do 475-500hp all in no matter what compressor is used. Huge difference. The injectors requirements of those turbo if run at even 80% of their potential are 15-20% more also

Love it thanks Bison for the solid info.

Since these are all older tech turbos, journal bearing I am assuming, would you recommend anything similar sized and power goals, stock heads/bottom w/ bolt ons but in a ball bearing / billet wheel to help with spool/power? I haven't fully experienced my PT61 yet but compared to today's more modern machines, the lag is very noticeable and I'm sure will get a little better once I dial it fully in. Little jaded by all my twin turbo daily drivers that light up like nothing

For stock heads with bolt ons it's hard to beat anything with a stage 3 turbine with the Garrett .63 ex housing. They spool really fast. T04e60 or 60-1 or an MFS equivalent wheel. Having a billet wheel of similar design and dimension will shave off 20-25g and have more blade surface area but that will be felt very little in spoolup. The small 57mm turbine with the Garrett .63 will require about 800rpm less stall @0 than a pt61 which is a 10 sec turbo and should have cam, heads, intercooler to work properly. I've done the MFS 5957 with a Garrett ball bearing cartridge and a Garrett .63 for the fastest spooling turbo that will support 55-58lbs/min. With that you could run 1000rpm less stall at 0 and have the same spool as a pt61.

What kind of power would the 5957 combo you ran approx net? Thanks!

 

[2QUICK2B6]

I ran a Te-60 it was awesome best 60ft was 1.55 on DR's 11.40 1/4 best 1/8 I think was like a 7.40 great trubo !

I didn't run it. It was built for an altitude car in CO that needs more compressor to offset the lousy air. All in it will go 10.70-10.80 if the combo is built around it. 57-58lbs/min all in. Most hit 45-50lbs/min with their old te49 or te60 turbos on stock headed engines. The MFS 59 compressor will support 62-63lbs/min. The stage 3 turbine will flow 58lbs/min on a good day. To get the full flow out of the MFS 59 a larger turbine is needed. It a winner with the old t4 69 trim, stage 5 and the new high flow 62 I use often. It also works well with the t0476 p trim. Easy 10 sec turbo with the larger turbines but converter requirement changes a lot with the larger wheels. 600-800 more stall at 0 needed to have the same Spoolup.

good info I ran a stock long block 50lb inj PTE front mount

Ever dyno your setup? I have 50lbs and a stretch IC, unsure of cams yet need to dig in a little further, block should be all stock on mine.

Calculator puts you around ~400whp? Don't have your data so really rough #'s

What turbo do you run now?

 

[2QUICK2B6]

no dyno just track #s it was a tad over 3,770lb with me in it

 

[2QUICK2B6]

im going to be running a dan strezo worked champion heads 212/212 cam with a 6768 dbb turbo billet with a pats non l/c converter lookin for high 9's on 275/60/15 dr's

 

[2QUICK2B6]

id say old combo with te-60 made 450 rwhp 28 psi on 116

 

[AllGoNShow]

Thanks!
