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...

mocked up...

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...

Sweet spray painted valve cover til i can afford that really late model 20V cover...

plumbing VVL solenoid and made a brace for that big ol intake manifold...

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...

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...

here it is in running form...

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...

Now thats a work of art. You guys always did do amazing work at MA.

the motor set up looks amazing! Are you bringing it to any clubloose events soon? I cant wait to hear/see it! Your set up last year was awesome and you totaly killed it at east coast bash! I can only imagine how sick this thing will be!

p.s paint the valve cover that awesome green!

dam sickkkkk... what offset are those wheels? what size tire you got back there? im wondering cuz im getting the 50mm overs also.

430 wheel? whats that at like 15-18psi????? badass setup.

if i ever go SR again i'm doing this with 2.4l. probably wont but hope to see you around.

What fuel are you using....judging by the grey coloured exhaust in the pics it isn't pump gas.

...its at 21-22 psi actually. We are pretty sure this .55 AR exhaust housing is choking us up a lot as the hp AND torque fall off pretty good up top(revving to 9500 rpm). Thinking of switching to a .70AR housing or maybe .76 divided if i feel like making a new manifold(which i will never have time to do now that the season has started).

Im going to try and get to a lot of east coast events so if we are at the same one please introduce yourself.

it runs C16.... i could probably run a lesser fuel, but its pretty common and i can bum it at the track if i need to. haha.


considering if we put it on a dynojet it would make almost 500whp i am pretty satisfied with it. Driving impressions will come shortly after Formula D Road Atlanta event which we are getting the car ready for now.

since its a slider i'd leave it with the .55 but tailor it to your driving style. or throw the .70 on there with a 100shot from 3-5k for spool up haha.

you are right about that 500 wheel dynojet. We just tested a joke of a car a D series with a sc61 @30psi. on a mustang it made 407 and on mine it made 441. the powerband looked like a 1000wheel supra.

Awesome work! any vids yet?

Damn Brian,
That engine bay is looking proper. Do you still have the stock waterpump pulley? I found that with my old setup, I could run 30+ psi with no problem, but as soon as I was consistently above 7500, the temps would rise. I should have tried underdriving the pump before going electric to see if that helped. The Davies pump/controller works fine though and whenever I come into the paddock, I can leave it running and the temp drops from 100-65 in about 30 seconds. Also, what about a larger turbine housing and some aggressive antilag:) Your intake and exhaust manifolds could definitely take it. Good luck in Atlanta!

no videos yet, but maybe after ATL.

Bill the water pump pulley is under driven and so is the ATI damper which is new for this year. Thanks for the kind words Bill, hopefully ill get to oogle your machine again in the near future.

brian,

i remember you had a higher displacement SR. can you give details and history about it. driving/dyno impressions and such. my love project is a ve 2.4 liter. when i hit the lottery i'll be sure to do it before a 2.6liter itb ka :)

Greaser,

this is the same short block from last year.... the 2.2L stroker motor. With the S256 turbo it make great, useable power especially on the bigger tracks. on tighter tracks you are working the clutch some, but i figure it out pretty quick. From my brief look at the charts Ray has here this thing makes about 80-100 more ft lbs. in the mid range (now makes 380 ft lbs peak torque). I assume this is due to the low/ high cam and the intake manifold. After ATL I really want to get a good graph plotted in RPM and not wheel speed so i can post it up.

Ray is telling me that the .70AR housing is the way to go... it might lose 1-200 rpm of spool but it will open it up a LOT. Also he thinks that with the rpm we are turning that the small exhaust housing is choking up the motor and keeping a lot of heat in the motor which could be part of our over heating issue.

Brian,

Any chance of showing us the pre VVL head and post VVL head dynos overlaid each other, or if that is not possible, at least both dyno's to do our own comparisons.

Cheers,

juggernaut,


im going to try and do that....hopefully sooner than later, haha.

that thing is awesome. I would love to get behind the wheel of a machine of that build one day ( i will build my own when the funds allow it). Looks like an awesome set-up making great power. Did you guys notice an increase in power-band with the VE head? Good luck at the drift events! :)

I'm very anxious to hear this thing this year! Should be interesting revving that high for extended periods of time and bangin limiter with the .70.

Here's a good sound clip from last year

Sounds ridiculous!

Wow, how high was that motor revving too? That sounded nasty...
