4G33 (4G16) Pony Tuning... how to thread.

[Jed118]

I've always wanted to see what I can do with a stock Pony 1.6L unit, and I have a good candidate: the one with the 4G63 in it now had a mildly tuned (super-aggressive cam, lightened flywheel, and electronic ignition) 1.6L in it.

I'm moving apartments soon, so I found my old exhaust headders from a Plymouth Arrow. I cut the old flange off it, and made an adapter plate.

Today, I went over to James' shop, where him and his cousin welded it up for me: it fits perfect. All I gotta do now is clean it up, reweld it again, clean it up, paint it, and install it.

So that's taken care of.

Tomorrow, I'm headed out west (waaay past hamilton) to grab an intake manifold that will accept a 2GC Rochester carb. I will purchase said Rochester (a rebuilt one for $125, good up to 350 CFM) and port out the manifold, and put it all together on the engine.

So, if I do this right, I could be all done by the end of february, so as to allot time for other, more important projects, such as the G4CS build up.

I will post some pics up as soon as I get some double A's into my camera.

Recap:

-Portmatched IM w/Rochester 2GC
-Electronic ignition (recurved dist) w/blaster II coil
-Headders
-wild cam (unknown specs, but it has a lot of overlap, and 3/8ths inch more lift than the stock one)
-Lightened flywheel (12 pounds)
-Free flowing 2 inch with one muffler, dumps before the axle

This is going to be a sick (quick) buildup... my blue pony will aquire this motor.

A custom manifold that will accept a 2GC... will be portmatched



1st pass welding



Obviously that needs to be cleaned up



... and painting

It used to have square ports



Im gonna have to clean the welds up, weld again, and clean it up again. Shouldn't take too long now.

The engine:







It's been sitting for a while so I freshened it up



The lightened flywheel, with one bolt snapped (has been fine for 10,000K)



The manifold, cleaned up



And portmatched! Actually, there wasn't too much to port match, I actually had to portmatch the gaskets after (take a bit off of them) as I over did it a bit.... that just means the head will have to be ported to match (which will happen later, not part of this buildup right now)

Compared to the Tiburon IM, there's not a lot of flaws at all, and it's very smooth allready, tolerances seem closer too, I'd say they got lazy as time went on, this is a very nice manifold on the inside... on the outside there's quite a bit of excess material from the cast. I took most of it off just for pretification.



Assembled! Waiting on carb

[Jed118]

Things to do: (for myself so I don't forget later, I don't own a PDA)

-Paint crank pulley
-Clean fuel pump
-Clean up the chaincase
-Reinstall waterpump pulley and belt
-Put back the electronic trigger in the Stellar/X1 Excel module space
-Clean the oil pan (so you can see ALL it's redness)
-Change said oil
-Purchase Blaster coil
-Hose clamp for head coolant passage
-Install one way valve for brakemaster into the new IM (from old IM)

The car:



Bad Ass!!

2004's Pony ressurection? I hope so, Cuz I got 6054 headlamp grills, just like 4 years ago!

check out that half primered tiburon! yayuh!

Jed, if you ever bring your arse down here, bring an extra Pony with you and sell it to me.

Hi Jed, its Mike.
Glad to see all my parts finding a good home!
It looks to me, from the email you sent, that the carb you are looking at is the wrong one.
I think what you need is the R3.
They give dimensions for the bottom flange bolt pattern.
If you still aren't sure, bring it out one night, and I'll measure it up for you.
BTW, while you're at it, if you haven't increased compression, or done any headwork, you should.
With that cam, you're going to want more compression, and those heads respond VERY favourably to porting.
The cam, if I recall (I have all the numbers written down) is a crane grind, and 246 duration at .050", and .278 lobe lift.
That would equal ~.473" lift at the valve.
Set intake centerline to 102-106 degrees for best results, the eaelier being the better with your compression.
Heres a pic of my championship car

[Jed118]

hah all I remember was setting the lash adjusters almost all the way to their limit! That's a CRAZY cam!

In addition, when on that site they have the rochester carbs

Rochester

when they say " has the SMALL bolt pattern on the base of 3 and 1/4" X 1 and 7/8"..", is that from the center of the studs, up and across (blue and red respectively, on the diagram)?


I ask because I have a caliper, and also the IM is allready bolted to the head, I don't want to take it off...

[Jed118]

also, I've heard that a cheap (free) way to increase compression on these engines is to simply wrench down on the head bolts...
