I wanted to share a little project we just shipped for a good customer. I'm not sure if they want to be mentioned since some of their competitors are reading, but they will chime in if they want to be seen.

This engine was designed for FWD road racing in an EG chassis. The races they run are sprint type circuit races that are around 30 minutes long. The goal of this venture was to provide a low maintenance program with a 2 engine rotation, and 320bhp output.

Engine Makeup:
133 Cubic Inch, 2189cc
-DART 226mm Tall Block
-95mm lightweight billet crankshaft
-Custom Lightweight Carrillo Rod
-Wiseco 15:1 85.5mm piston with tool steel 19mm pin and raised comp height
-4 Piston Outlaw B16 CNC Cylinder Head
-PAC HD valve spring with pressures setup for up to 9500rpm
-Skunk2 Pro 3 Camshaft, using Skunk2 Lost Motion Springs
-ASP Custom header for clearance of the DART tall block
-Customer has 52mm ITBs currently that will run the first race of the season, then will fight for their life against a Skunk2 Ultra Intake manifold, and set of larger Kinsler ITBs...amongst others.



The project starts with a new block from DART. I'm always surprised that this block was never a big seller in our market. It is a LOT more popular for guys to take a 10-20 year old block they picked up for a few hundred bucks...and despite being blown up, in car accidents, through thousands of heat cycles, cold winters, stripped bolt holes, cracks, etc....people would rather spend $1500 waiting weeks on end sleeving that for their race engine. Nothing wrong with that because the sleeving companies do a good job, but this DART block certainly has a lot of advantages.


This project was under a huge time constraint, so being able to call DART and have a block here 2 days later was important. The crank, rods, and pistons were made to order, so money was spent on expedite services and UPS and FedEx made out like a bandit.


The 8.898" tall deck allows us to safely run this larger stroke, and over a 6" long rod. How many times have you heard of guys running under max bore size so they they can save their sleeved block for an overbore and rebuild down the road? Or guys tossing blocks because they damaged a cylinder at max bore and can't replace the sleeve? No problem with the DART block....you can easily replace one cylinder sleeve or all.




KILL or be killed


Astro Glide for assembly lube...LOL j/k. Gotta make sure everything is rubbin together right.


Deck clearances, bearing clearances, valve clearances....all meticulously set within our in-house rules, no exceptions. Sometimes that causes headaches if things aren't measuring out like you want them to, but in the end it pays dividends. This one came out just right. Its like a closely guarded family recipe.


A3 Beryllium to pull heat out of the Ferrea Super Alloy exhaust valve.


Our Outlaw B16 sized right for this motor....300hp all motor, 1500+hp turbo...no problem. Git R Dun




CNC ported Skunk2 Ultra manifold in development


Luke complimenting Matt and Josh on their hard work to meet the deadline.


ASP custom header showed up on time thanks to Stefan and his wife. They do great work and the headers always perform and have great fitment. Note....fork lift drifting taking place here. The road course we setup was too much...It handles like **** LOL


Time for shipment....Josh here taking a break to take a customer call.



Thanks for taking the time to read. There are a couple more right behind this one in 92mm and 98mm, so I may just post those up in this thread instead of making new ones

What is a ballpark figure for something like this? 5k? 8k? I know each build is different, just wanting an idea on how many limbs I would need to sell...lol

What's the cost of built short block and assemble head to block with degreeing?

F22Master

They have some base prices on their website: http://www.4piston.com/shortblocks.html

I was just wondering what an all-out build like this costs.

What crank is that?

Might I suggest Endyn's dart block service it is legit. I got my tall deck from a friend. It was a brand new build and like Endyn said the fifth main was wearing down bad. I hade them clean the block up and picked up a 95mm crower crank.

dudewheresmy...

Thanks for the post on the tall deck. I'm just getting into a tall deck dart build myself(used engine) albeit mine is for a turbo application.

Its hard to find any up to date info on these motors, so I've been doing a ton of digging lately and came across this thread.

I have a few questions and I can give you a call or pm, if this is too OT for you...

-Who makes the crank that you are using for these builds? have you used one of those in a turbo build? I'm going to use the current 95mm eagle I have for a bit, but I want to know what options are out there.

-Also i'm trying to wrap my mind around setting up the timing on the tall deck. I understand change in deck height alters cam timing, but perhaps you can provide some more info on the subject?

-How have you found the timing belt whip? Do you recommend the use an aftermarket tensioner?

This is a nice thread.

To the guy posting endyne info, I'm sure they do good work, but it's quite rude to post that in a 4piston thread.

I have a dart talldeck that I threw on the back burner.

Perhaps I should send it to 4piston to finish...?

And where's the dyno plot?!

i would like to Know What series this car will be runnning?
Also if its just a Time attack car?

What is this oldschool VX if an Ultra was CNC'd?

Everything about this build is pure sex. That intake manifold is dope

I love when 4piston post stuff

Doctor patient confidentiality I'll have to ask how much I can share.

Chugger

What timing belt are you utilizing with the taller deck. I have read that its a ford zetec belt from a focus or escort. Is that a gates racing belt?

4piston

It is a Gates Racing Belt

Wow....wish I had the funds for a block like that
