turbos

[TurboSnail]

i wanted to by a garret t-70 for my 1985 m30 engine . can i spool that turbo properly. what the biggest turbo i can put on my car. i know bigg isnt always best!

[russc]

T-70 is way big. Unless your running 600whp, forget it. If its free, well, its still too big...


It will spool like a dog on a M30 engine!

ok . well i kinda thought so. they have emm on ebay for $239.00 bucks new. so if any one has a car that can spool that got get yur self one. but how about a t-6 or am i still aiming to big . i have a t-3 turbo thats rebuilt but i think that one would be a little small.

i had a deisle turbo . but i gave it away cus the exaust housing had a few cracks in it. i feel dumb i didnt check it out better but it was a cheap lesson luckly.

umm so recap " what size turbo should i buy" preferably a garrett turbo!

and dose my car have enough displacement to run two t-3 turbos?
these Q's are more of curiosity than idea. but i do think twin threes would look nice under my hood. if it was possible .

[russc]

Those sub-$400 turbos on dabay are all cheap chinese knock offs that won't last more than a few years. If you wan't to go that way, be my guest.

Did you look at TCDs website for the turbo he uses, or my site.. those ones are good.

T-3 is pretty small. Yes, you can use two, if you wan't to fab up a custom exhause or try to find an old Cartech unit.

The TO4b or TO4e like TCDs are the right units.

ok well i will keep that chines knock off thing in my head when i go on ebay next . yur right on the cheap part i went and looked again. there cheap like you said. so go for a t-4 then an i should be happy. as to the twin 3 Q cant i just bend my header and well a flange on it and bolt my t3 setup to that and run the waste gates linked to one vac line with a T on it and then spen hrs adjusting them? i have a two peice exaust header there iron with steel down pipes. would this be suficent . i saw another bmw at the track built his turbo manifold ths way.

is a garrett t3 super 60 ok to use?

HOLY RUN-ON SENTENCE BATMAN!

Jeezus, I have never written that poorly, even when in elementary school. Dude, by being lazy, you come off as an idiot. Take your time and create a post of which we can decipher some information!

Way too small, IMO. Just take a look at the compressor map. Youll be off the right side in no time. Its almost too small for my 2.0l nissan engine. I highly recommend that the original poster go pick up a copy of Maximum boost and read away. Many of the questions being asked will be able to be answered with a little research.
As to making a manifold, I am building a manifold adapter from weld-els. I had a little free time last night and did a quick and dirty mock up for next weekend.

I think the duct tape will be fine

T3 flange?

Did you port the exhaust manifolds to match the head now that they're inverted?

[Brad D.]

I figured Id just rock the duct tape too. 8) A freind had a blowzilla which, for those that dont know, a Gt40 comp wheel with a t3 hotside. Now I if I hadnt gotten such a good deal on the turbo, id be running a t4 flanged turbo. However, the good news is that its a 76 trim t350 turbine wheel(the largest t3 wheel if I read correctly) in a .82 A/R housing. This should be roughly comprable to a .58 T4 housing, albeit a tad smaller. Well see how it works out.
I do intend to port the manifolds as they done quite match up when iverted. I havent dont it yet, but its on the list of things to do.

yea i will try to write better . im not realy all that good at it . so if you could just bare with me please .

You could've started with that sentence! To wit...

"Yeah, I will try to write better. I'm not really all that good at it, so if you could please just bear with me, I'd appreciate it."

jsut so you know, t6 is the flange and not the turbo and anything that has a t6 flange is made to support over 1000 rwhp and isn't even efficient until upwards of 30 psi. so without a $30k built motor, a t6 turbo is useless on a m30 (or any) motor.

i went to my local auto yard and got a turbo from a saab 900 i think it was an 88. could any one tell me what the specs on this unit. it has "TB0357" on it . thats ware i got my t-3 some body told me it would work. mabey im the dummy here

Perfect size fro your lawn mower but not your m30.

how about two t-3 one on each manifold? would that make for fast low psi stable boost pressure? like peak 15psi but steady 9 psi? question of curiosity please dont shoot lol

twin turbos have shown little to no gain over a single turbo -- plus -- fitting two turbos in the engine bay requires alot more creativity and skill. One turbo, correctly sized -- is all you need

yes one would be nice and easy wouldnt it. i think im just going to try my t-3 on for size and then later buy my self a hybrid t3 t4 . they mount up the same dont they? flanges , oil , and water lines.?
