I think I'm gonna go for it. Majestic turbo rebuild on my stock Hitachi HT-18, plus the 46 trim wheel on the compressor upgrade, and a 10 degree clip on the exhaust side. All for 650 beans. Anybody got any words of encouragement? Ridicule? Lets hear it! https://www.nopistons.com/forums/pub...#>/biggrin.png

Be careful with them. A friend of mine had his 87 TII turbo done by them and it lost its oil seals after nine months of driving. Ask them if they have fixed this problem or if they have gotten seals that can withstand the heat of the rotary. They told him it was the heat that caused the seals to go bad.

I didn't know there was more than one shop. This place is in Texas. I thought I heard they were the best.

Why not just upgrade to a T04? I see them on eBay for $425 all the time. A T04 manifold would run you another $200 or so.

I don't know if I would trust a turbo from ebay without having it rebuilt and balanced. If that thing comes apart, I've got to buy me a new engine.

They are brand new.

Hmm. I'm intrigued. How hard is the connection to my existing downpipe in the stock location? Is the turbo and manifold a simple bolt-on, or do I have to fabricate stuff? I've seen none of these turbos, but then I haven't been looking that hard. Just figured I couldn't touch a new turbo for less than 2500 or so.

Okay, so there's T04's on ebay. Is a .60 on the compressor and a .96 on the exhaust appropriate for a rotary? Is the oil and coolant feed and return the same as the stock turbo?

:sigh:



I always see this reply. ''why not go full to4''



If you're going to4, you'll have to buy the

1. turbo

2. manifold

3. oil and coolant lines need to be made

4. the downpipe is going to need to be custom

5. stand alone and lots o' fuel

6. front mount

7. You will probably want an upgraded radiator

8. Wastegate



to4 conversion is not a cheap process
