cp pistons 12:5.1
hytech 4221

edelbrock victor x intake
70 mm throttle body
550 cc injectors
on e85 mapt bij sneaky tuning (Nl)
Made 271 crack and 240 nm

now my record on track is smasht by 1K serie and 1 H serie so now i wanna build the fastest biggist b serie engine
and i like to get some info from you guys

So far
dart engine 2lr
carillo pro A rods
And fuily skunk head
and pro3 cams or brian crower

now coms the question
What do you think

i like the rods... theyre light and good for your application by "track" did you mean zandvoort? if so... pls post vids would love to see your track runs

Pistons and compression = since you have e85 on access
i would shoot for something like
13.5:1 / Custom Wiseco's or custom supertech's is what
id choose, theyre light and generally good priced

camshaft : your idea of a Pro3 works, although id like something that
peaks torque a lil higher (not just higher in figure but higher in rpm too)
m24xx or m25xx comes to mind, ive ran pro2,pro3,m24xx's and for track
id lean towards the m24xx ....pro2 and 3 are good.. but mostly theyre for
drag (not to say they wont work for roadracing lol)

just dont go brian crower LOL

headers : the Hytech style 4-2-1 big tube tri-y would be a good choice
but you should also consider your ground clearance with that
as it hangs a bit lower than most.... but if ur not overly dropped or lowered
it should be fine...

a few tips and tricks to the exhaust will get you more oomph
+ some intake tweaks...

this is a fun project pls keep us posted

I have to warn you about Dart blocks.
I almost insisted to my builder (Endyn Dyamics) that I wanted to use a dart for my max effort nitrous motor being built.
Larry told me without hesistation that it was a tremendous ammout of machining to get one of the Dart blocks in order which nearly doubled the cost alone. It is very touchy in every area and has to be prepared perfectly for use.. Not even the crank thrust washer surface is machined.
He explained that the ONLY reason to go Dart was for the taller deck, period.
Larry also said that He has see no stronger motor than the Darto MID sleeved B series blocks.
Food for thought.

 

ENDYN = energy dynamics (so endyn dynamics kinda sounds too much) just playin LOL


good point... while ive no experience with dart blocks ive seen some odd porosity too personally (someone else's build i watched etc)

might be safer to go Benson or GE i believe GE sometimes carry some LS blocks already sleeved etc

 

Thanx i need to translate some of the answers tonight because my english is not the best haha.
The track we drive on is drachten
You can see a shot of the old car on youtube .
Sneaky tuning all motor hatch
Not the best run slicks to big but fun to watch.
I wanna go dart because the machine shops her are crappy .
Last year build a fuily build b16 turbo.
And my darton leeved block.had manny sadbacks.
2 times on dyno i had a dropt sleev so
I dont like sleeved engines annymore
Car would be build streetracing and track only

 

OK, problem one with B20 blocks, the head gaskets don't match correctly.
GE blocks are strong yes, (I am building a seccond one now for street use) and it's a GE sleeved; the step deck and epoxied sleeves make ANY repairs a real hassle. Darton MID can be repaired very easily and has an excellet reputation.

 

i agree on all accounts bro...

the GE was a suggestion as step up from b20,

the Darton MID is a step up from GE LOL but yeah owner is in alot better situation
going with either or (the above) than a dart

we havnt had problems using the b20 (non b16a) gasket on b20vtec's
a couple of them road racing doing alot of laps not just 1/4 drags
but yeah.. they do require some work to get it right..

good point there btw i missed that out
