Budget 4.0l interest

1slow370 · 05-21-2021, 06:08 PM

I'm getting ready to bite the bullet on R&d'ing a budget 4.0 stroker kit and want to gauge real interest. It would be ideal for 7500rpm and lower and FI applications up to 700ish whp. For an extra $7-800 it would be good to just about 1000whp if your head gaskets can hold it. Now here's the kicker core block plus roughly $3000 for an ASSEMBLED short block. Lmk so I can see wether this is worth putting time into

Just to clarify this would be roughly $4k cheaper than a Brian Crower kit

Who's crank? Billet or reworked stock?

Can't give away all the secrets lol it's a forged crank and not reworked, just adapted. And it may be no Bryant billet tool steel deal but it works and it's not $4000. It has all the heat treating and features it was Originally born with.

Also it will work with any standard vhr piston(stock or aftermarket) just lower the rated compression by a point. So stock vhr pistons would be about 9.9:1

Edit as a side note stock vhr pistons actually put up to quite a beating if you treat them right

Well this is going on deepfreeze lol won't get the rods until September. 18 week lead time.

Got an e-mail from from one of the venders I deal with the other day. Off the shelf machined parts will take between 3 to 9 weeks. Special order machined parts could take up to 9 months. Depending where it is coming from. California has the longest lead times.

Some forgings is 24 months. Unless you want to pay the money to jump the line.

My King off road shocks took 5 months. I have gun parts still trickling in from last Dec.

It's going to take 3-4 months for my upgraded turbos

Wheel size doesn't change diff ratio just tire size. Are you running a Miata height tire?

Edit: with a 3.33 rear gear you would be running a 24" tall tire to get back to a 3.69 ratio vs ~26.5" tire stock

DailyZFan · 06-03-2021, 11:22 PM

What is the install cost on this?

1slow370 · 06-04-2021, 10:19 AM

Well the r&d motor is pushed way back into fall so it's hard to say anything for sure but it would be done as an ASSEMBLED short block
