stroker/turbo
« on: January 01, 2019, 07:02:47 PM »
I am doing rebuild on a 258.  I am wondering if adding a turbo is worth it and if buying a stroker kit would be worth it and what all would need to be replaced to make this safe?  This is my first rebuild, so I apologize if terminology is wrong or the questions seem stupid.

My 2.73 geared eagle can do faster than 108mph, it can get a rubber squeak into 2nd gear. It walked past a crown Vicky that was chipped to stop at 108mph. However i was beat off the line i had to fight to overcome that in 4th with a sr4 trans.

Anyway it is stroked with parts from a 94 H.O. 4.olt, so the 7120 head and whatever cam the 4.0 had. Its carbed with a mc21??. Not gronk garbage btw. True dual exaust no xover. It has msd ignition all around. No turbo

Of course this was probably a closed course type thing not an interstate or highway.

others will chime in on exactly what is needed but basically is a 4.0L with the crank out of your 258
so to create a stroker you are going to need a 4.0L engine

Its just swapping the crank and rods, from one to the other. You should also go to the machine shop to get everything looked at and polished up.

There's is plenty of info on the web regarding building a stroker. Check out jeepstrokers.com. There is a bit more to just throwing in a crank and rods into the 4.0L block. You need to pick the right pistons and head gasket so you have proper squish to resist detonation.

Squish is more of a 2 stroke term, I should have used quench.
