hey guys, i have been playing with a crazy build up of a 3.1 turbo and I finally have the money to do so. I have been looking around at what I could do. I found a site that makes forged connecting rods and pistons. And I am going to have a custom crankshaft forged made as well. I have found the Chevy bow tie block gm made out of aluminum that lighter and better built block.Also do the 3100 top end swap with ported heads and extruded intake manifolds. my question is should i buy a tgp motor and switch its stuff over or just buy the crossover and rear exhaust manifold off someone and bolt it up to the new block?
neither. just buy a TGP with a non stock x-over and cut to the chase.
agreed you dont need a "monster build" to make very good power.
id use a stock tgp bottom end and jus giv'er
(look at my sig.... a Stock minus 1.6 rockers tgp motor)
Kuntzie- you car is all stock other then roller rockers? How do you pull the numbers you do with a stock setup?
a huge vacuum style squirrel trap

They're stamped 1.6 ratio rocker arms from a 1994-1995 3100, not rollers. ;)
About the only COSTOM crank you can get is the 3500 or I think it was the 3900 crank. THink it had larger jurnals. Slap on some crower rods and dimond pistons and call it a day.
Problem isn't making power...its getting it to the ground..IE..transmisson mods, axle geometry, slicks.

true, making power is as easy as adding more air and more fuel.
The TGP was designed to give us all a head start on those. tougher tranny, better suspension/steering, wider wheels.
...there is power locked up in there that the stock parts could use just fine. port match all the intake gaskets. throw on the possum fan, re-tune it.
just make sure the car is capable of putting that power down to the asphalt..... wait, I gotta go all. I am going to get new KYB GR2's on the Black Widow!!!! forgot, today is the big day!!!!! my project car gets new front end today. struts, new rack and pinion, axle boots.

Read it again, he's going to have a custom crank forged for him. That should be cheap. When you get the form done, send one my way, I'll paypal you the shipping cost. LMK.
So you're going to take an Bowtie block, stuff a fully forged bottom end in it, top it off with ported 3100 heads, extruded intakeS, and then throw the stock exhaust manifolds on it? That should keep the exhaust temps up!

Sir, buy what you posted it is obvious that you have failed to do the necessary research to build a 3xxx motor to any level of HP for less than $100,000,00. The forged crank will cost you near 60k for a one off. Don?t think you will be putting together a group buy because the crank is the strongest part of these motors and people building these 3xxx motors are using stock cranks, prepped yes but stock.
As for the 3100 swap, that?s yesterday?s hardware and I don?t think anybody on here at this point in time would even consider that swap when there is much better hardware to be had.
And yes you can bolt the TGP manifolds and xover to the 3xxx family of heads.
You got the 4k for the bowtie block and machining?
With you next post why don?t you ask these guys how to build a 3xxx motor instead of telling us what your going to do which is not within reason. Your crank will be worth more than most all the TGP?s on this forum put together.
Welcome to the forum.
Is that better Dave?

Jud, I used the PM function for the reason to keep it "Private" but since you asked me in the open forum i will reply in the open forum.
Yes thats good and lacks the name calling from the previous post you made in which i deleted and PM'ed you about.
no problems here but it didn't have to surface in the active tread..... :icon_confused:
