Like Steve said, they will spin up to 8.5k with the normal rods, or 9.5k with the long rods like Vicious has. What do you care anyway, Peter? Don't you shift at 5k at the track? :stick:
Uhh.. no I go up to 6... theres no power after that anyway... on my car.

I dont launch hard if thats what you were getting at. :razz2: Ill launch hard when i have a 4 bolt and its not my daily driver... back off.

Chill out! I was just giving you shit. Notice the little guy poking the other one with a stick!

LOL, You ladies need a time out card. HAHAHAHA

Even with the long rods, the rod ratio is still in the 1.5's, the difference is so slight, I'm not even going to bother. I've never heard of anybody going higher than 8500. I'm building one because I still want a streetable car, so spool is a concern, running 9's is not.

Steve, are you keeping your 60-1 or going with something different? What does that turbo spool at with the 2.0? With a 2.4 it should spool something like a 50 trim right?

For now at least, although I'd switch to the 8cm exhaust housing once I got the car tuned right. I was hitting 30 psi by about 4000 rpms.

I see, I am anxious to see how that 2.4 spools that big GT 56 trim that Jet has. My god that turbo is a big bastard, he showed me that turbo last night and it was actually scary looking.... :lol: So much for his 3" buschur cold air intake since that turbo has a 4" inlet!!!!!! Time to just throw a filter right on the turbo and call it good huh?

A little info on the 7 bolt 4g64...2.4 liters, found in 94-98 galants is SOHC form. It uses all 2G parts, front cover, etc. except for the cam gears and timing belt which are replaced by '94 galant DOHC components. 5 cooling holes need to be plugged on the block. Rods are the same as 2G rods. Only one case of crankwalk I have seen, and that was due to a build error. There are no oil squirters, but according to Magnus they are not needed...

This is a good way for 2G guys to get away from crankwalk, gain .4 liters, fast spoolup, and massive torque all without doing a 6 bolt swap.

And it'll be fun to beat some of the 1G guys and tell them you are still running a 7 bolt ;)

I do have one question, assuming your turbo was large enough, wouldn't the same boost yield a much higher airflow, and therefore a substancial increase in HP while keeping knock and EGT's at a minimum?

BTW, I have heard of a few people hitting 8k+ on the 2.3/2.4s with the stock valve train...

I wouldnt know, but i would think that running the same boost on a 4G64 would require slightly more airflow, which could put the turbo outside of its efficiency range and create more knock, if anything at all.
