1989 Horizon Masi project

[Vigo]

The sky is the limit for wheel selection in 4x100. If you want to keep the whole world of wheels as your oyster, don't swap to 5x100.

Looks like a great project, good luck.

I found them. what size pipe does it fit?

They say it fits 1.5" weld elbows in schedule 10, 20, and 30. I found that the schedule 10 fits it best, the thicker fittings will work as well as they are just smaller inner diameters dumping into the collector that has a larger inner diameter. I used schedule 10 because it fits the masi oval exhaust port best as the circumference is the same. If I used schedule 40 fittings after ovaled they would have been smaller that the exhaust port on the head. The collector ports are about 1.7" inner diameter.

So you're gonna make Masi headers for everyone now huh?

[joelzip]

I would love to! I'm expecting the turbo to take forever to come as I have dealt with Comp turbo before and they move sloooow. I ordered it from Cindy a few weeks ago. Once I get it I'll be on it right away. I will probably list my original factory cast steel manifold for sale afterwards as well.

Cool build, And yes a rust free Omni/horizon is a great feeling. Just a heads up with those eagle rods on a 2.5 crank, You need to use Srt4 bearings. If you use the bearing from a 2.5 the tag will be too wide and will not fit into the eagle rod.

[joelzip]

Crank is a factory forged 2.2 masi piece, rods and bearings are being narrowed to fit the journal as the masi journal is narrower than the others. Got the rods / bearings/ custom pistons from Forward Motion. Still haven't heard from the machine shop. The block is at Koffel's place, this old dude used to make custom billet cranks in the 80's for these cars! Retired from Chrysler. He is also the guy who sold Diogo a pallet of new old stock masi heads. If the crank doesn't work out I might resort to a regular forged 2.2 piece. This is one of Dave Koffels rides, a 1939 chevy and guess what powers it...

Awesome horizon project!

That 39 Chevy... The air filter is before the smec... That's different. Lol

[Keito]

I work 5 minutes from the Huron shop
I've talked to Scott a few times about 16 valve heads
At least you took it to the right place.

[2.216VTurbo]

Looks like we can add Koffel's '39 to the list of Masi motors that needs a valve cover gasket

[85boostbox]

Is this a cb motor? I will be taking the crank out of my race motor for a cast crank. Let me know if you go the forged way. We can work something out.

[GLHNSLHT2]

Awesome, I always wanted to put a 2.2/2.5 into an old ford or something. I would of done a Water/Air setup on it though. and I wouldn't trust that SMEC to be air tight. Still very cool.

Subbing... Looks like a cool build! My wifes grandpa use to have a rust free 88. He is a old drag racer and no matter how hard I tried I couldnt get him to swap it. I had been told that he was going to sell it to me if he ever got rid of it and he gave it to his 17 year old granddaughter. Poor thing .

I'm interested to know how well the Comp turbo works out. You are going with the 58mm inducer compressor wheel IIRC. What turbine and turbine housing? I've shied away from both Precision and Comp simply because they don't have any compressor maps. I don't trust "word of mouth" and the general "well, in this motor it did this...blah blah blah". Somebody else's set-up is NOT mine, and there are VERY few people that have put a large turbo on these engines to make big power. If a company makes turbos, they had better be testing them to see how efficient they are. I simply don't trust them when they don't advertise what their products are capable of or that they even tested them.

[joelzip]

I'm hoping to be cruising this summer with it, I have chosen a 56mm .63 a/r exhaust t3 housing for reduced spool as its a stick shift car. I have 4 more of these turbos on other cars and they have been trouble free. They have aluminum center sections that are great looking. Cindy at fwd has experience with them and the sizing so I bought it through her.

[Reaper1]

Are the other turbo's you have the same size on a similar sized engine? I'm interested in spool and power.

[joelzip]

No, two are 6765 on a twin turbo 421 chevy, two are oil less 6562 on a 427 olds. Thats why I bought from Cindy as she has dyno time with them on these motors. What I've picked up over the years is that its all compromise, almost impossible to make a combo that spools faster and makes more power than another turbo. One will spool faster and make less power up top and the other will spool slower and make more up top. I think almost all aftermarket turbo companies like precision, comp, turbonetics... use garret exhaust wheels. They just make their own bearing / housings / center sections / custom billet compressors in house. To make the most power on pump gas you have to deal with slow spool and a large turbo as to not make as much heat and prevent detonation. The person that wants to make the most power with pump has to deal with crappy lag time no way around it. So I compromised with this size to get hopefully 400 wheel on pump 20-25 psi and maybe spray meth to push 500. The turbo is rated for 600 ish but that's way out of efficiency range. Here is a good read on a Honda thread about a similarly sized turbo on smaller 1.8 liter motors They are spooling later at 4000 rpm but we have 20% larger motors to reduce that. Still pushin 400 horse on pump. http://honda-tech.com/showthread.php?t=2953731

what do you think a used masi head from intake mani to exhaust mani would be worth?

[168glhs1986]

I'd be interested if your selling....

[4 l-bodies]

what do you think a used masi head from intake mani to exhaust mani would be worth?

Joel hard to really say. Prices on these are all over the map on these. I've purchased complete 16V TC's for as little as $1600. They were rustfree, but rough interiors. I know of two others that sold for low 2000's. Both were 60K mile rustfree TX cars. Then there have been ultra low mileage TC's selling for over 10K. I nice 16V 37k mile TC went unsold on eBay last week. Highest bidder was around $5500. I think Ron (Viperbox) found his complete motor cheap. Others have spent $2500+ on NOS 16V upper half.
Just looked at a 89 TC yesterday for a friend. This is 8V turbo 39K miles. Nice car but will probably only bring about $4500 tops.
What's the deal? giving up or found another?
