1st i want apologise myself for my bad english...

I started the motor last fryday, ill be street tuned tomorow and Dynoed soon
I want you guy's opinion on the power it can do wit that set up
The set up:
-B20 84.5 DART bloc 226mm deck hight
-97mm Eagle restroked crank ( 2.180L)
-151mm Rods
-Flat pistons -4cc notch for 11.4:1 P8R head shaved .020
-P8R head Ported/flowed at:

- 252CFM@.500 Lift
- 229CFM@.400 Lift
- 196CFM@.300 Lift
- 157CFM@.200 Lift
- 83CFM@.100 Lift

- Ported Si-R ( P30 ) IM 63mm Throttle body
- B18b 95 intégra Intake cam B20b 97 JDM ex. cam
- AEM cams gears
- Stock valves and B18b springs (no B20B springs)
- Modified LS air box wit Stock filter (ran my old LSVTEC set up at 202Whp)
- Tri-Y headers, 15" of 2 1/2" exhaust line at headers and 3" balance
- 3" reson and 3" muffler No cat ( same than my old LSVTEC set up)
- P30 chiped wit Hondata S200 (basemap P-75)
- Fuel regulator seted up at 42psi IDL

Car ran already good. In my 95 Integra 2001 ITR tranny 1st gear is too strong dos'n hookup at anny RPM and i ad my best tires
Did'n push too much the motor in 2nd gear, but look like it will not hookup past 3500rpm
I did the set up to mak Torque and i wish 160 WFPT will comout of it
and B18 cams use to make little more HP than Torque, so Hoping a 170WHP Lot of HP for stock cams
HP = Torque X rpm / 5252
If i can get 150Fpt at 6000rpm Y'm done
Y should i make 160FPT. i doo beleve that the stroke will ad 15FPT from the stock B20 that wee ran at 130 so it make 145
ading the 2 pts of CR i doo beleve in 5FPT
and the Air Flow from the P8R head will make the rest
I'm y dreaming ?

Very nice setup, in for the dyno, where you are going to dyno this torque monster ?

 

Same place where i got 203Whp wit my LSVTEC and run 13.0@105mph so i think HP are really thrut

But also maybe try new place.

And wat ever the result of the place i will go to i'm going to

REDLINE performance try is dyno for free

this should be fun. any reason your not going with hotter cams?

 

Yes Short in time. and it going to be my winter beater
If Torque numbers are good Crower 62404 wit springs/reteners should make the final toutch

 

i was thinking 403's or 404's would do AWSEOME on this motor. And with a head flowing like that you wont have kind of problems hitting well over 210hp i think once a set of the crowers go in

 

seems to be a solid build, in for dyno sheet i wanna see this torque monster, those darton blocks cost a sweet dime.

 

Not Mutch

The valves cover to tune it

 

DO you have any picture of the modification you did to the intake ?

 

No. I just open Throttle side to 63mm and wit a flexible extension and a sanding weel, i try to make begening of each port in the plenium bigger than the exit ( funnel) and a little polish ended wit 320 grit

 

I was more reffering to the fitting job on the LS head.

 

haaa Sorry not realy. Ill try to make some wit my other Pr3 also prepared B20b

 

Here is 2 P8R heads non vtec to compare the mid stud that you need to lift from nonvtec head to fit Vtec (Pr3-P30) IM
Bothom head is modified Bolt in the oil plug (wit helicoil)




Here is the water pass tapered and the Upper last IM stud that going to need welding on intake Manifold to drill the hole aligned wit the stud
