MA-Motorsports SR22VET Engine build for 2009 Drift season...

[Brian W.]

So last year we built this car...

http://www.freshalloy.com/forums/showthread.php?t=183318&highlight=s256

over the course of the year we had a couple issues with valvetrain since we were revving it to 9500 every weekend at drift events. Ray and I have been talking about doing a RWD SR20VE for some time and apparently we werent the only ones as Mazworx has that sweet kit now!

So we got ourselves a long block and sold what we didnt want from it... only making back about $300 if that.

Well...

here are some pics...

while the motor was at the machine shop i borrowed a head from a friend of ours so i could start making an intake manifold. I got the parts from RMR and got to work...

milling the runners off the oem SR20VE intake manifold...

cut some holes in the plenum extrusion and cut the runners to length, here i am deburring the plenum...

here we are all welded up...

Again, motor was still at machine shop so we machined the ATI damper for the 60-2 tooth trigger wheel for my Electromotive Tec GT. We also milled the 5mm off the back to compensate for the VE oil pump drive...

I got a bunch of these made(i still have a few if anyone needs one)...

We also had to address the turbo manifold dilmena... instead of just hacking up my full race i sold it and we made this guy...

all welded up...

I got this AIM MXL Strada also for a smokin deal from a customer too. It hooks right up to my Electromotive ECU and we also added some other sensors to log like EGT, oil temp, and all. It reads my NGK wideband also... its REALLY neat. And Ray was happy we had it when he had the car on the dyno...

Well i FINALLY got the motor back from the machine shop and I got right to work putting it together...

http://i79.photobucket.com/albums/j123/JDMFresh/S7300041-1.jpg

i ended up using an S14 short block so we plugged the VTC feed with a 1/16" npt plug. I had to weld an extra ear onto the VE oil pump to get that one bolt in also.

Here is our VVL plate we made on our bridgeport. Its pretty damn simple. We decided to just feed both cams with one solenoid to simplify things. This means we can only control one cam at a time, but thats not really a big deal. I counter sunk the holes too for more firewall clearance. not needed at all, but it looks neat...

http://i79.photobucket.com/albums/j123/JDMFresh/S7300040-1.jpg

you can see here we cut the oem VVL solenoid block off and drilled and tapped it for 1/8" npt... we then welded a bracket to it so we could bolt it under the intake mani like so...

here she is about done and ready to go in the car. In the process of making a new mag sensor backet for the crank trigger. Thats me in the background... i lost about 15 lbs. since making that intake manifold earlier in the post... haha...

BAM motor is in the car again!...
http://i79.photobucket.com/albums/j123/JDMFresh/S7300065.jpg


And i made this coolant expansion tank. We had some cooling issues last year so we are gonna start with this and maybe switch to an electric water pump set up if need be down the road...
http://i79.photobucket.com/albums/j123/JDMFresh/S7300066.jpg

crossing things off the list as we go!...

Also new for this year is an oil cooler and an Accusump. I had Griffin send over this core and i welded some brackets and fittings on it...
http://i79.photobucket.com/albums/j123/JDMFresh/S7300068.jpg

coolant expansion tank all done with -4 bungs welded on...
http://i79.photobucket.com/albums/j123/JDMFresh/S7300067.jpg

here it is in running form...
http://i79.photobucket.com/albums/j123/JDMFresh/S7300085.jpg

and a pic of it on the dyno...
http://i79.photobucket.com/albums/j123/JDMFresh/S7300083.jpg

Ray tuned it today and it made 430 something WHP on our dyno dynamics. I was working on other things all day but tomorrow ill get more info and maybe get a graph up.

everything works! now we have another list of things to do to the car to get it ready for Formula D Atlanta in a couple days!!!!

i need some sleep! haha...

[robunicu]

i've been folowing this on ziptied... sick ride bro... and i so want to c how this motor will run...

[Ceepo]

Wow that is impressive, thats alot of plumming ha ha ha, sweet build man definatly a beautiful motor, alot of time and thought went into that...

[xpertsnowcarver]

Outstanding. Curious though, what made you decide on that length for the intake runners for both motors?

[Z33dori]

wow ... i'm so glad you were able to get it all finished in time for Rd2... hopefully you can put on an awesome showing for the big GA.....

def can't wait to see some video

[Om1kron]

this engine sucks Brian, so you should just give it to me. kthx.

[Z33dori]

lol

toss a ls1 in it.. lol j/k

[Brian W.]

Well on the 08 motor we did not build the intake manifold. It was a JUN intake that we did not modify. This year we through this one together and really i just made the runners as long as possiblein hopes of gaining some more midrange power. We have built and designed headers with tuned length runners but my car doesnt get that kind of love. =/ haha.

[Ali 556]

Nice,

time for stupid questions....DET head made 420ish whp...and you went threw all that for an extra 10ish whp....

i was thinking that VVL head will gain @ least 20-40 whp....over the DET head @ the same boost :ughd:

not worth it if you ask me...

Simpler more reliable valve train.

I love you Brian

I believe they were lookin for a higher revving engine coreect me if im wrong

[swayray]

bad ass motor brian! did you ever go w/ the SR16VE cams? what did you ever do with the distributor cap?

Yeah the real reasoning behind swapping to a VE head is the better rocker design for the high revs. put this car on a dynojet and it would make almost 500whp which is pretty serious for a car that only weighs 2360 lbs so more power isnt really needed(yet, haha). :cool:

<3

We revved the DE head just as high, but we are hoping this one will be less prone to problems. =)

bad ass motor brian! did you ever go w/ the SR16VE cams? what did you ever do with the distributor cap?

Ray! We are using the SR16VE N1 cams you hooked me up with. As for distributor ... i dont need one. Ray lathed up an o-ring plug that bolts in its place.

[allntrlundrgrnd]

Damn that s13.4 sr was so sick, but this is just awesome. i still have a pic of it on my phone from when i picked up my motor haha

the green regas look rad too, keep it up brian!

[ZX88]

is this going to be at east coast bash in may???

[Z33dori]

more than likely .... if it is that is worth the 8hr drive itself

[Brian W.]

thanks guys. Yes it should be @ ECB.

[Ghostdrifter]

Brian what's the exact color of those green wheels. That's the green I want to powdercoat my enkei rpf-1's(but with gold flake of course :).

WTF....so VVL head + S256 @ 18psi = 500 whp....:werd:

And DET head + T3 S256 @ 18 Psi = 420whp...

Damn....so every one should swap a VVL Head...gain = 80whp...:dead:

or i'm wrong...?

no you would be wrong. the car only make 10whp more than it did in its prime last year. Last year it took about 2-3 more psi to make the power that it makes now. Again, i didnt do this for more power(but for a more reliable valvetrain)... i was simply stating that if this car was on a dynojet it would make almost 500whp (last year it would have been about 486 dynojet) which i think is plenty of power for what i do with the car is all.

Without a graph i guess its tough to see the other gains over the fact that it has a more reliable valve train design. the torque curve looks pretty flat though which was not as much the case as last years motor.

[SmogSUX]

Looks sick as hell. Does VET indicate the variable cam timing?

[SlideWell]

this thing is sexual! :coold:

[Devil Man]

wow that is some very impresive tooling you did there. im gonna go ahead and say this is the nicest looking SR set up i have seen to date. very clean the intake is amazing exhaust mani amazing all of it really is just good. let me ask though what did you do to your tranny to put up with the 9k+ revs? im guessing that your running an aftermarket tranny but thought i would ask anywho

[Brian W.]

thanks! the Trans is a Z32 setup. It shifts better at high R's than the stock SR trans but still requires some persuasion sometimes, haha.

[azndoc]

Build looks sweet BW.

[rsibley22]

this car makes me want to buy an fittings for everything haha ... someday

[Z33dori]

"STRAP BRAKER"

lol

[Brian W.]

thanks guys! buttoning it up today and heading to ATL tomorrow morning.

[steve shadows]

I alwasys love your Builds Brain!!!

Very cool stuff man, holding it down with the real deal SR setups on the east coast while I on the west.

+ you rock the Dyno Dynamics for tuning.

You are going to tune on that sucker agian right?

You guys should spend a lot of time in steady state with a knock sensor, EGT and wideband you could probably get some unbelievable spool up out of the motor with a VE head and larger disp

rock on!

[fishhouse]

favoritest car ever. i hope it has zombie vinyl on it now.

[UNITEDMASTER]

Very nice,always pushing it in the engine department. So how far out will this one rev???

[Brian W.]

only 9200 for now.

[yokotavia]

i like the "only"...
haha

an 9200 revving SR sounds so wrong......
you guys do crazy shit over there at MA

[Neejay]

only 9200 for now.
only? lol

Good job. That's a very nice build.

[Neejay]

Have any videos of it?

[turbo_dreams]

Nice build, Can you feel a great increase in tq after 4k where both boost and vvl is fully engaged? I'm guessing you're using pfc for management?

[smelly240]

the fwd guys rev those engines to 9500 pretty regularly - those guys are stupid tho - they stop making power at like 8500. stupid NA guys.

[Brian W.]

yeah the power falls off up top, but its still useable. mostly due to the small exh. housing and limitations of the N1 cams.

[Brian W.]

oh, no real good video yet, but after ECB im sure their will be some.

[landins13]

im glad i got chance to check the car out while was there. you guys do great work, and i completelly accredit brian and ray for the fact that my car is running for the first time in 2 years.

great people+ alot of knowledge+ great quality= MA motorsports

[surge s14]

beautiful build brian

[WoolyS14DET]

Borat Voice==== VERY NICE !!
I wan see sum vids !!!

[burnsauto]

brian, think you could post up a shot of the cold pipe? I'm interested to see all that intricate welding, and how you went about fabbing up the pipe itself.

Also, Im considering using the VE head as well as GTI-R ITBs, and fabbing up a custom collector tank. Will the ITB's flange bolt up to the VE head?

[PoorMans180SX]

I really want to see dyno graphs.

Also, why did you not make the manifold twin-scroll? Even if you put the single-scroll turbo on for now, at least you would have the option later. It seems only right when you now have a more efficient head.

[blo0d]

So last year we built this car...

New Funtimes machine for '08... - FreshAlloy.com Forums (http://www.freshalloy.com/forums/showthread.php?t=183318&highlight=s256)

Guys, sorry to bring up this old thread... but what does it mean to fire one cam at a time? at what point do you have both cams activated?

[slider2828]

He is talking about VVL in the SR20VE heads instead of both intake and exhaust VVL.

[jr_ss]

Guys, sorry to bring up this old thread... but what does it mean to fire one cam at a time? at what point do you have both cams activated?

The P11 VVL heads used a twin solenoid activation system, where I believe(don't hold me to it) the intake cam would switch over to high lobes at a seperate time than the exhaust cams. I'm not sure what the switch over points were for either cam.

However, when the VVL head is bolted to a RWD setup, people ditch the twin switch over system and usually switch both cams at the same time. I'm sure there would be gains to be had switching both at seperate times, but I think they are minimal at most.

Regardless, if you have an S13/S14/S14 rwd SR, this does not apply to you at all. The VVL's were only available on the FWD NA cars and the AWD SR20VET which is extremely rare.
