Well I thought I'd share my build that I put together over last winter and got it running late this past June. I decided to put together a 84.5x89 GSR motor that i was going to daily drive, not just something that was gonna be driven on the race track or just the weekend, but driven everyday. I had the block and pistons sent to Golden Eagle to get resleeved had them do the final bore and hone on it. Spent the winter gathering the parts piece by piece and eventually got it together, running, and finally base tuned. I wanted something that was gonna be reliable and so far so good, 5000+ miles. Well onto the build:

Head:
Blox TB
JG Victor Intake Manifold
Hondata IM Gasket
Ported GSR Head w/ Rocket custom VJ
Rocket Cams
Rocket SL Valvetrain
Supertech Stainless Steel Flat Faced Valves

Block:
84.5mm GE Sleeved GSR Block
89mm Stock LS Crank
LS Carrillo Pro-A Connecting Rods
8cc Supertech Pistons

Fuel:
Walbro 255lph pump
RC 750cc Saturated Injectors
E-85 Ethanol Fuel
Compression is approx..14.1:1 Static

Brand new gaskets all around. Engine was assembled and degreed by myself. Here are some pics and results.

The numbers aren't the highest but this is just the starting point and there is still room for improvement, this is also on a loaded Dyno Dynamics dyno also so it reads similiar to a Mustang type dyno. Thanks for looking


And finally the dyno sheet. These are of the same run, whp/tq on one graph and whp/afr on the other. This is through a RSR Ex Mag exhaust, I thought the exhaust was holding it back since its only 60mm through a resonator and baffled muffler. Everyone knows how "quiet" the Ex Mag is so we dropped the exhaust and picked up 12whp bringing it to 242whp on this Dyno Dynamics dyno.
I didn't get a chance to get that graph but this one through the exhaust will do for now.

nice results

so how is it driving 14:1 on the streets daily?

 

drives fine, rips hard, and at 2.85 a gal i don't mind it Gotta save up for more dyno time and see what I can extract out of it.

 

great results... congrats

yes i would also like to know what its like driving a 14cr daily?

im building a 12.5cr daily b18 and wondering what fuels to use...??

cant wait to see ur times...

 

I was told golden eagle recommends you send them the pistons as well and have the whole bottom end assembled there. Why did you choose only to get the block sleeved? I'm looking on doing something similar to my B20.

The results are impressive however!

 

I shipped the block and pistons to Golden Eagle and had them do the final bore and hone to the block. They also measured the pistons and did the piston-to-wall clearance also. I chose to assemble everything myself. Golden Eagle

Well see what it runs at the track, its a full weight EG Si hatch so i think it should be 2300+ lbs with me in it.

 

Good numbers :-)

I would definitely try & figure out why your a/f ratio is leaning out so harshly at around 7300 rpms along with why your powerband has a nice dip in it there :-)

I would also suggest trying to smooth out the air fuel ratio through the whole powerband.

 

Which of the RM cams are they? 24x's? Is vtec set at 72~ish? Either way, man-o-man am I jealouse. Love your rods and head package....what header was used?

B U E N O

 

VTEC is at 7200 right now but we're working bringing that down, header is an custom AN-R standard "style" header. There are still gains to be made, there are different things that i will be trying out so the numbers should hopefully climb...either way, 242 whp open header on a lower reading dyno isn't so bad i don't think...who cares, its just numbers anyway

Oh wow, the 25's! Yeah no matter what way you look at it, the motor makes #'s...especially a 242 on that specific dyno.

 

wow good stuff .. over here , we have to pay over $4.00 just for 91 oct

 

Good lord thats a big *** vtec lobe lol!

 

[QUOTE=clean rice]Good lord thats a big *** vtec lobe lol!

I agree. Very nice tho.

nice did you take out timing to drive on the street or you running just like how it was on the dyno?

im jw because im doing a k build and was thinking on running 14:5:1 and needed input on e85 running that high daily

 

m25 is nice, I love mine.... VTEC@6000 here...

242 is not so bad, the tuner says that bone stock GSR's only put down between 136-139whp on this dyno so idk if it reads avg., low, or high..

No, i didn't have to pull timing to drive on the street, just did some street tuning as well as dyno.

 

those valvesprings are sure getting a work out.
how many miles are you going to go before a inspection...givin everything holds up well?

very nice setup. those cams scare me alittle "e"

lol!

 

here is one more pic for U then about m25

 

Slowsleeper
. Slowsleeper is a great guy and built a great "bio fuel" motor. Congratulations again. He graduated from a technical university that has a engine performance curriculum. Also has good writing skills--a plus in my book. But unlinke most engineers his mind is flexible and not rigid and not limited to "rules" set in da books. Always been very respectful and smart enough to try to learn and understand and then trust when you have to take some things on faith. Another great thing is he budgeted and didn't actually go to crazy but at the same time any motor built from the ground up is going to take up some serious coin, especially for young folks.


Cylinder Head
Here I'll give credit to Exospeed. This head was ported by Exospeed and used by Slowsleeper on his 1.8L. Slowsleeper sent the head to me to see what I thought and what it needed for this new Bio Fuel Motor. I told him the ports looked really good (scrores an "A" on the report card here), similiar to what I have seen from Alaniz. I reccommended that we re-do the VJ. The custom VJ was cut on a Newen G2 (RLZEngineering also has this machine--Brad uses his machine a lil differently than my guy).

Here is the pic of the head after the VJ re-do. This VJ is designed to work with the 30 degree backcut on the Supertech Flat Faced Nitrided Valves. There are racier VJ's from RLZ but for this app, ST valves and mild lift cams, this VJ works great. [Combustion Contraption, notice that this is a lil different than what a B16 port would want. We can discuss offline.]



Pistons and Rods
The rods are the Carrillo Pro A's. Very nice rods with very good bolts from SPS, a long time aerospace fastener company. I am still a big Cuningham Rod fan but that was out of the budget.




The pistons are very nice pieces from Supertech that at the time were "custom" for me. Big thanks to ***** and Martin Tagliavini at Supertech for being good for making products with features racers want. I love CP Pistons and we used them many other builds such as Hot Rod Turbo but again, not in the budget for the Bio Motor.

Very nice features for a shelf stock piece.



Cams & Valvetrain
Don't really need to say more here. Just providing lift and duration and valve control. Pretty simple. Still too complicated for da *********** here--you know who you are.


Tune
I checked out the tune. It looks pretty good. Just need to tweak a couple areas to get it to transition harder into the big hi cam, allowing for a lower vtec point.


Header
Here I think Slowsleeper can make some good gains. There are some new 4-1 imported headers coming soon. I would like to try to those out on this motor.


Hypothetical
If the Bio Motor got some pimp Jenvey ITB's from DonF with the big air horns this motor would "have it all" but again out of da budget.


Closing
Great job Slowsleeper. Classy guy with good patience and discipline. Also degreed the cams perfectly the as a first timer with $35 with of tools (indicator, stand, and wheel).

Rocket can you share more info on this?

BTW nice build and results Slowsleeper

 

Header is supposed to be coming soon; customs is always a biatch.

 

Props.

 

you going to run it on the 13th?? looks great!! i'll have to give you a call soon.
