Intercooler swap

My “95 still has the original intercooler in place with no issues. I’ve read that the 24V intercooler flows more air and can lower EGT’s better than the stock unit.

Who has done this and what was involved in the swap? It’s not a direct fit but can easily be done.

I don’t have a need for an aftermarket unit and this seems to be the next logical step before a turbo upgrade.

Thanks

The 24v intercooler is IIRC 1 or 1 1/2 inches taller than the 12V intercooler. I doubt that lowers the ETGs much.
I am sure on a 2nd gen it would be a bolt in or very close to it sort of deal.

I have 12V and 24V intercoolers in my shop, if you end up needing one.

In my humble opinion there are no benefits to a "better" intercooler at the power levels you are talking about. Maybe a slight reduction of NOx emissions under high load, (some 2-4%) and no significant benefit in EGTs unless at extremely high air temperatures under very high load.
This is for a good stock 12V intercooler, in case of it being dirty or defective the IC may cause high EGTs, but fixing the problem will not need modifications in the IC system.

I've run up to 500 RWHP with the stock 96 IC without any need to "improve" the IC.
