Misc Upgrade Questions

[jaredo]

2G GSX

1. Can you just throw a 1G TB on a 2G without porting the intake mani first? Or will this actually disrupt airflow more then leaving it stock for the time being.

2. Can you just throw a 1G intake mani (and ported exaust mani) on without porting the 2g head to the same size as the 1g runners. Or will this cause airflow disruption.

3. How easy is it to replace the retainers and valve springs when insalling upgraded cams.

4. Can you replace piston rings and or pistons/valves without pulling the engine.

5. ACT2600 / xact flywheel combo on an engine with stock internals bad idea?


Basically my car has been in the garage for a few months and I have a 1g throttle body, intake mani, act 2600, xact flywheel sitting around. Going to work on the car today, just trying to make a list of things to do.

Thanks

2. i hope you dont mean put a ported 1g exhaust manifold on.

3. if you dont have any experience doing this or a manual, you may have som trouble. but since the head is a apart, the job itself isnt that bad

4. definity not easily if you can, you will probably spend less time pulling the engine then doing it with the engine in

5. i know a few people running that combo with stock internals and no problems

IMO you should wait until you can afford to do all those upgrades at once (if you cant currently), get a set of arp head studs and then just pull the head, replace the valve springs (and valves if needed), port the head to match the 1g intake and put the 1g tb on the 1g intake. If your compresson numbers are good I wouldnt worry about the rings, they "can" be replaced with the block left in the car but chances are if the compresson is bad enough to warrant new rings it probobly should be bored anyway, and if you are putting a clutch in it and having the head off your 99% of the way to having the whole engine out anyway.

What about throwing on the 1G TB and Intake (will that cause issues)?

Issues w/ 1g TB? No.

1g t/b and 1g intake to a stock 2g head. Just wondering if the intake would actually cause airflow problems (if the runners do not match the head)
