One way is to have your heads and intake manifold ported. Thats what I did. Also do some research on V1/V2 intake manifolds. The word on the V1/V2 is mixed when compared to porting the stock one. Alot of opinions out there. Good luck- Brad

Depends on the performance, and including visual goals.
Are you looking to go faster than low 11's?
Are you going IC'd?
Do you want to maintain the "stock look"?
Do you want to keep the turbo in the same location?
Yes for now I would like to go at least low 11's.
Yes on IC'd.
Don't care about stock looks, this is a driver not a show car.
And no the turbo is not going to be in stock location.
Thanks

In this case, stick with the HA manifold or use the 87 manifold.
Too many underestimate the design and features of the stock HA manifold.
God luck with the project!
Well that is what I have now. I just welded an aluminum 90 degree elbow onto manifold. Stock Throttle Body is ok then??
I am planning on getting pt6776rh with t3 4bolt turbine housing .63 A/R. What kind of cam do you suggest?? This is a stock bottom end. Getting a 3-3500 stall too.

Do a search.
MANY opinions on camshafts, and here is mine.
With that converter (If it is a true 3500), you can go up to 224@0.050 on the intake. Bigger is not better on a TR.
Call Mike at FullThrottle.
Here is my $.02
There are TOO many options with your email. Intake wise, I am choosing a 86-87 modded intake. The reason why is in 86, Buick engineers found something that made them change their intake for 86 other than intercooling. Leeo, Jamie, Brent and others have ported them and got them to work. What really got me to thinking was the late Bruce Plecan. Do a search on 87 Hot Air or post by Bruce. He went unconventional and took off his intercooler. He compensated with alky. Leeo was the first to get a HOT AIR in the 10's. Bruce had a 600+hp GN he took the intercooler off and actually discovered faster spool and better response.
By modding the 86 intake, one actually could go from a HOT AIR to intercooled in10 minutes or less. The intake could be plumbed like NOS for alky or a plate under the plenum.

By using the latest intake Buick made for our cars (86-87), one could spray alky or NOS or even propane in the up pipe. Intercooling could be another option once the HOT AIR combo has been maxed out. Using a stock GN intercooler or the latest Ebay special. Also by using the 86 intake, this moves the throttle body off the turbo. Older Spearco kits did not idle right because of this.

I have an 85 engine that I am planning on transplanting into a 74 apollo. I installed a fwd intake by flipping it backward so that the throttle body was in the front and planned to run the stock turbo in the 86-87 location with fabricated up and down pipes. the only drawback I can see from this set up is that I am having trouble using the stock acc. brakets and pulley set-up, alt. is the way of the throttlebody and the intake ports are somewhat smaller. I wanted to intercool this and choose a powerstroke intercooler as I have plenty of room to mount it in the apollo core support. would this set up not be simalar to the 86-87 config.? comments?
Not sure about the config.?? But the 86-87' pass. side header won't fit, will it? Because of the alt. in the way?? Can you send me pics of what you have I am interested in that manifold setup you have. I had been looking at those but wasn't sure if it would fit??
Thanks,

I will take some pics when I get a chance, may be a little while the engine is over in storage and it;s like 0 degrees here. as far as the header goes I was going to modify the 85 headers to relocate the turbo, is there an advantage to using the 86-87 header? also it won't matter on the alt, it is in the way of the throttle body, could turn the manifold around and have the throttle body at the back,just would require more boost tubing to route it all. not sure if making new brackets or boost tubes would be easier. I have thought about using the 86-87 acc. and brackets(cleaner look anyway), but I have been unable to locate a set.
Sorry I retract my earlier statement, lol. I didn't mean the Alt., I meant to say A/C compressor bracket. I must have been tired or something. But yeah whenever it warms up a lil I would really like to see what the manifold looks like on there.

I know it's been over a year now and nobody cares, but has anyone ever tried this before, anyone see a drawback to this? the only thing I see is the size of the throttle body, does anyone know the size of a IC TB?
BEFORE
AFTER
If you look at the underside of the intake you'll notice that the water passage isn't right. It will come off of the back of the heads not the front the way you have it mounted. I have one of these and was thinking of doing it to but the intake has to be mounted in the original position to use it. Sorry to be the wet blanket on the idea.
Lets explore for a minute why this would not work. I see what you are saying, the flow to the thermostat would be off the coolant passage in the rear of the heads instead of the front. Would this be so bad? The flow of coolant would be from the water pump, around the front cylinders and be forced to the back cylinders, into the heads and out to the thermostat and onto the radiator, did I miss anything?
If you look at a lot of the NASCAR engines that pull coolant from the back side of the cylinder heads as a hot spot or steam pocket forms and causes the back cylinders to run warmer. This might have been were the idea for the LT1 cooling system was pulled from, it has factory steam pipes from the rear of the cylinder heads and come forward to the radiator.
Any Ideas?

The problem you run into is the coolant flow. The head gaskets have a blocked section at the front of the engine to cut down on water flow in the front of the engine. If you reverse the head gaskets then you end up with no flow through the block. If you run them in the normal posistion then no flow through the heads. The only other idea you might be able to do is block the water passages in the intake and run an external thermostat off the freeze plugs at the front of the heads. I'm not trying to be a wet blanket but I've had the intake for over a year and haven't found a way to use it except in the factory position. I think it would be better than using the hot air intake because there's not as much in the way to restrict flow of the air. The only other thing is the mount for the throttle body has a smaller inlet but a good machine shop could fix that without a problem. Now if someone would come up with an intake to run seriesII heads on a 109 that would be one h*ll of an idea.
