i have the same turbo but think imma change housing to something bigger from the start...like to an .81 or possibly a .96 but i doubt the .96 what do u guys think?..i think the .68 would boost too quick for daily driving i want something that spools hard in mid-range and top-end..???????????????????

The .68 is too small for a 346 engine.

I have a MP T-70 with an oncenter .96a/r ex-housing and it spools very quickly and seams to make great power ( I have not been to the track or dyno yet). I will say my car feels quicker than it did with the TTI T-76 at the same boost level, and the car put down 523 at 10 psi with that turbo. I think they are a great bang for the buck turbo if you don't need more than 650rwhp (with a front mount system).

So it sounds like a .96 exhaust housing is sufficient. Do you have any pictures of your setup?

I have the same set up. I put the .96ar housing on mine, and it spools almost instanatly. I couldnt be happier with the turbo. Now its time to go bigger.

SUPER DAVES Z

Definatly go with at least a .96a/r on ALL T-4 turbos that will used for a front mount single turbo system on ls-1's. This will help keep the exhaust pressures as low as possible when making 600+rwhp.

I will try and take some this weekend and shoot them your way.

Pictures would be great. Everyone seems to think that a MP T70 is not big enough for a stock cube LS1. Its good to see that it works well in milder applications. I am looking for a mild combo with 500-525 RWHP. Keeping boost levels as low as possible while getting that power level.

What cam are you running Dave?

It'll do 500-525 rwhp easy. A couple of mustangs have made 700rwhp with the T-70 on 306 and 331 ci motors. I'll probably max out the kit before the turbo. So far it's been a great little turbo for me, considering it cost around $600 total (this includes the $50 for the .96a/r housing from ebay) and I have an extra .68 tangental housing (which I need to sell). I'm going to see how close I am to my buddies PTK cobra (running a PE 76-GTS 550rwhp at 10psi) and that'll tell me about where I am.

I have a lunati single pattern cam (real similar to MBI's B cam) 221/221 .558/.558 on 114.

so is this to small for a my 355 sorry new to FI will A/R.68 choke up on the topend

SUPER DAVES Z

iTrader: (6)

The T-70 will work, but your right the .68 would choke the motor. You would just want to swap exhaust housings (there are 2 main parts, compresser and turbine). Best thing to do would be call Jose buy a turbo from him. He know's damn never everything about turbos and he can get you components that would work perfectly for the set-up you have in power range you are looking for.

Like Dave said the 68 will choke that motor off quick, especially with a p-trim wheel.

Jose

whynot

So Jose, what t70 would you recomend for a mild 355 then (650 rwhp +/-), running mild boost (around 15 psi) limited to 7000 rpm's?

iTrader: (19)

i would aslo like to know thanks

JZ 97 SS 1500

If I had to buy a 70, if space limited the 70GTS, if not space limited then a GT42-70. Leaves you room grow to large compressor wheels without having to redo the system.

how much bigger is the gt42 to the 70

whynot

hey Jose, how would this one do? 810009

JZ 97 SS 1500

iTrader: (2)

Externally its a good it larger. I will see if I have some pics.

That unit is even smaller, since its only a T3 flange unit.
