My SR20VET...
Well, I've been building this for the past year or so. I had a built S14 SR but threw a rocker arm, hated life, and went VVL. This is my timeline and progression on the build thus far.
The Specs: Stock P11 head w/ SuperTech DVS and stock cams for now... Mazworx VVL conversion kit including IM My old forged SR20DET bottomend ID1000's Walbro 255 to surge, Bosch 044 from surge to rail GTX3076R My old Peakboost manifold Exedy Twin Disk Intake manifold and Q45 TB... http://www.tamparacing.com/forums/at...up-vvl-007.jpg Huge intake ports... http://www.tamparacing.com/forums/at...up-vvl-008.jpg Super clean valve train w/ Supertech DVS in the highest seat pressure available for high RPM. http://www.tamparacing.com/forums/at...up-vvl-009.jpg Forged bottomend with VVL oil pump bolted up... http://www.tamparacing.com/forums/at...up-vvl-011.jpg BNIB Exedy twin disc I found locally for a killer deal. http://www.tamparacing.com/forums/at...up-huh-088.jpg Manifold mocked up on the head, I figured out here the factory fuse/relay box were going to have to be relocated, oh well... http://i627.photobucket.com/albums/t...g?t=1308431457 I overlaid my VVL intake gasket on my S14 SR gasket, its amazing how much bigger the ports are. No wonder this head flows so much better. http://i627.photobucket.com/albums/t...g?t=1308431457 Lot of parts that came in to get the head bolted on to my block... http://www.tamparacing.com/forums/at...up-vvl-003.jpg So I wanted to get the VVL head flowbenched, just to have some figures in hand and verify what I had been seeing on the web... The top numbers are the VE head and the bottom numbers are from a highport SR head. Flow test was done on a completely stock SR20VE head. Machine used was a Superflow 600 test bench at 28" of H20 and low 80's temp. Intake Lift CFM .050 49 .100 86.2 .150 122.6 .200 158.6 .250 192.5 .300 225 .350 249.2 .400 263.5 .450 272.9 Exhaust Lift CFM .050 46.5 .100 86 .150 118.5 .200 147 .250 171 .300 183.5 .350 188.8 .400 193 .450 196 For some added information, I've done some search on Highport heads and found these numbers... intake test at 28in H2O, temp 88deg F Lift CFM .060 43.4 .080 60.7 .120 92.9 .180 134.5 .260 175.6 .340 192..3 .440 201.8 .460 202.3 .480 203.5 .500 203.6 exhaust test at 28in H2O, temp 95deg F Lift CFM .100 41.1 .140 75.0 .200 98.2 .240 106.5 .280 110.2 .360 113.0 .440 114.3 .480 114.7 .500 114.9 More to come... |
neat! what kind of power are you looking for?
|
nissan should of put these heads on the sr from the start haha
|
Continuing on with the build...
I purchased Tomei adj. cam gears, Mazworx proprietary headstuds and an Apexi HG. http://www.tamparacing.com/forums/at...up-vvl-003.jpg With the parts above I was able to get the head bolted up and cams/gears installed... http://www.tamparacing.com/forums/at...up-yep-142.jpg http://www.tamparacing.com/forums/at...up-yep-144.jpg http://i627.photobucket.com/albums/t...g?t=1310325622 I cut the mounting tab off the DET water neck, ground it down and bead blasted it to get it back to a factory texture... http://i627.photobucket.com/albums/t...g?t=1310325605 I stripped, degreased, bead blasted, and had AN fittings welded to the VC. Then I painted it with Duplicolor paint and cleared it... http://i627.photobucket.com/albums/t...g?t=1310327863 http://i627.photobucket.com/albums/t...g?t=1310327863 Somewhere at this point I took the motor up to Mazworx. I wanted a professional shop to set up the cam gears and make sure they were on centerline. While the motor was at Mazworx, I cleaned and organized the garage enough to squeek the car in. Now I could finally start tearing the remaining items out to prep for some repairs and paint. http://i627.photobucket.com/albums/t...g?t=1310603240 http://i627.photobucket.com/albums/t...g?t=1312420891 One of the repairs needing attention. Some how rust formed between the pinch weld here. I had to drill out spot welds, remove the damaged metal and reweld in a new piece... http://i627.photobucket.com/albums/t...g?t=1312420866 After a few weeks the motor was ready to be picked up. Being that I was out of town on business for a few weeks my father picked my motor up for me. Once it was home, I started bolting items back on to it... Exedy, Mazworx trans adapter plate and VC bolted on... http://i627.photobucket.com/albums/t...g?t=1320623391 Modified waterneck to accept the S14 SR's 1" coolant hose... http://i627.photobucket.com/albums/t...g?t=1320623289 I mocked up the IM once more for the hell of it... I forgot how huge it was until I bolted it on every time... http://i627.photobucket.com/albums/t...g?t=1320718989 http://i627.photobucket.com/albums/t...g?t=1320719001 My turbo finally arrived, so I rushed home after work to slap it on. Obviously it was for mock up purposes only, but it looks pretty sick... http://i627.photobucket.com/albums/t...g?t=1321060184 http://i627.photobucket.com/albums/t...g?t=1321060199 http://i627.photobucket.com/albums/t...g?t=1321060198 Thanks for looking, more to come... |
More....
Like I said in the last post, I cleaned the garage up enough to get the car in to begin the engine bay strip. http://i627.photobucket.com/albums/t...g?t=1322011825 http://i627.photobucket.com/albums/t...g?t=1322011746 I recieved my TougeFactory surgetank kit minus the pumps as they were already in my posession. My only gripe with the kit was that the return line that they supplied with the kit wasn't long enough to reach all the way back to the surge tank, so you had to splice in a short piece of pipe. I contacted Jamie over there and explained my concern, he had a piece long enough shipped to my door within a few days time. http://i627.photobucket.com/albums/t...g?t=1322011773 http://i627.photobucket.com/albums/t...g?t=1322011786 http://i627.photobucket.com/albums/t...g?t=1322011811 http://i627.photobucket.com/albums/t...g?t=1322439295 http://i627.photobucket.com/albums/t...g?t=1325975888 Incase you missed it, my Walbro 255 will be the lift pump to the surge tank. From the surge tank I'll be using a Bosch 044 and -6an lines to feed 1000cc Injector Dynamic'c injectors. http://i627.photobucket.com/albums/t...g?t=1325975838 http://i627.photobucket.com/albums/t...g?t=1325975903 Before I bolted my Z32 trans to the back of my VET I had it rebuilt. It had started to develope the typical 4th gear grind and I didn't feel like having to pull the trans when it finally went. http://i627.photobucket.com/albums/t...g?t=1322439215 As usual thanks for looking, more to come... |
I actually started the bay strip while it was outside. I removed most items out there simply because there was more room to move around the whole car. Once it was actually in the garage all that remained was the front suspension and crossmember. Once they were removed, I started welding up the holes left when I removed the factory battery tray and the area on the passenger side strut tower. I wasn't looking to plug/patch all the holes in the engine bay, although in hindsight, I should've. I also used holesaws to clearance and make the holes I made for IC pipes truly round.
http://i627.photobucket.com/albums/t...g?t=1322439274 http://i627.photobucket.com/albums/t...g?t=1322439260 http://i627.photobucket.com/albums/t...g?t=1322439236 Here's the repair needed on the passenger side strut tower... I also removed all seam sealer forward of the rear of the strut towers. I was going to be torn up during the bead blasting and made sanding much easier. http://i627.photobucket.com/albums/t...g?t=1322439253 http://i627.photobucket.com/albums/t...g?t=1325975804 I brought home our bead blaster from work to clean any and all surface rust off before I started to body fill areas in the bay where I had welded/ground. http://i627.photobucket.com/albums/t...g?t=1325975829 http://i627.photobucket.com/albums/t...g?t=1325975803 3M undercoated the fender wells after I degreased and sanded them down. I went all the way up to the upper frame rails simply because I wanted to. http://i627.photobucket.com/albums/t...g?t=1325975888 After a shit ton of hours, sanding, body filling and sanding more, I finally got it where I wanted it. It was an huge amount of work. My hands ached for days and at times went numb from the process. I kept telling myself it was going to be worth it in the end.... http://i627.photobucket.com/albums/t...g?t=1326763199 http://i627.photobucket.com/albums/t...g?t=1326763199 http://i627.photobucket.com/albums/t...g?t=1326763210 http://i627.photobucket.com/albums/t...g?t=1326763225 Once the sanding had ceased, I had to wrap the car in drop cloth for laying down the primer. I wiped the bay down a total of 3 times, making sure I didn't miss any areas that could potentially cause problems. First two times took a total of 3hrs, I called it a night after that. I did a thorough final wipe down right before I sprayed the primer. I hit all the problematic/tight areas first, to make sure they were coated, then I came back and bombed the rest. I am by no means a professional painter, but I have a fair amount of time behind a spray gun. http://i627.photobucket.com/albums/t...g?t=1326763229 http://i627.photobucket.com/albums/t...g?t=1326763240 All primed... It turned out pretty damn good for a make shift paint booth in my home garage. It was a great relief seeing the car all one color, it started too actually look like something. http://i627.photobucket.com/albums/t...g?t=1326763243 http://i627.photobucket.com/albums/t...g?t=1326763270 http://i627.photobucket.com/albums/t...g?t=1326763261 http://i627.photobucket.com/albums/t...g?t=1326763252 As usual, thanks for looking... |

Sr <3 I'm looking forward to this build, definitely following this one .
Props bro. |
The guide coat was probably more of a PITA than actually sanding and prepping for primer. You had to sand a certain way otherwise you get high and low spots from the pressure of your fingers. That and getting into all the tiny areas to make it completely smooth sucked.
http://i627.photobucket.com/albums/t...g?t=1327283599 I don't have any pictures of the entire bay completely sanded without seam sealer, but you get the idea... http://i627.photobucket.com/albums/t...g?t=1327283610 http://i627.photobucket.com/albums/t...g?t=1327283610 http://i627.photobucket.com/albums/t...g?t=1327283600 And with the tape removed. When Toby said that this stuff sets up fast it was an understatement. I literally finished the driver's side and it was already setting up and becoming difficult to remove the tape. Luckily I didn't leave it all night like he did. It was off within 30mins of applying the sealer. http://i627.photobucket.com/albums/t...g?t=1327283624 I finished seam sealing at about 12am, had the car on the trailer by 1am and at my shop by 2am. I didn't want the car sitting outside in the dewy air so I moved some trucks around at the shop to get it in there. I had an appointment at 7am to drop the car off for paint so it was a huge push to get it ready by then. I dropped the car off and 6hrs later I brought it home, painted and cleared. The guy I used does amazing paint work, I couldn't be happier how it turned out. http://i627.photobucket.com/albums/t...g?t=1327283656 http://i627.photobucket.com/albums/t...g?t=1327283640 Don't go anywhere, there is still more... |
So now that the bay is painted, I could start cleaning all the components that were going to find their way back into the bay... Here it is a few hours after bolting things in.
http://i627.photobucket.com/albums/t...g?t=1327801806 http://i627.photobucket.com/albums/t...g?t=1327801804 http://i627.photobucket.com/albums/t...g?t=1327801818 While the crossmember was out I bead blasted it and had it powdercoated gloss black, I think it turned out rad. I bought Nismo steering rack bushings and new inner and adj, outer tierods from SPL. http://i627.photobucket.com/albums/t...g?t=1327801780 http://i627.photobucket.com/albums/t...g?t=1327801780 Adapter to convert my hardline to accept an AN fitting. http://i627.photobucket.com/albums/t...g?t=1327801829 Instead of the traditional install from the top, I opted to hoist the car up and roll the motor/tranny underneath and lower the body on to the crossmember. This helped for two reasons, I didn't need an extra hand and it kept me from scratching the paint. http://i627.photobucket.com/albums/t...g?t=1329704566 http://i627.photobucket.com/albums/t...g?t=1329704576 http://i627.photobucket.com/albums/t...g?t=1329704578 The motor is finally in and bolted up to the frame rails... I slapped the manifolds on just to get an idea. http://i627.photobucket.com/albums/t...g?t=1329704590 http://i627.photobucket.com/albums/t...g?t=1329704604 Because of the limited clearance I have behind the head and my bulkhead, I had to use Mazworx CAS kit. It plugs the original hole on the back of the head and installs through the front of the head. http://i627.photobucket.com/albums/t...g?t=1329704566 http://i627.photobucket.com/albums/t...g?t=1331512744 http://i627.photobucket.com/albums/t...g?t=1331512769 http://i627.photobucket.com/albums/t...g?t=1331512778 More to come, thanks for looking as always... |
So beautiful, and motivating, I am just about to go to work at putting my vvl head on, let me know if you have any advice.
|
everything is soo clean. bravo on the good work.
|
very clean!! good luck!
|
Very clean indeed loving the attention to detailing the motor looks amazing props.
|
Glad someone knows how to do shhh right
|
My hat is off to you sir ! Awesome work!!
|
Awesome bay! I will be doing the same thing come this fall/winter. Any tips or tricks you can give that you encountered during the whole process?
|
Bay looks awesome, even better with the engine!
|
Man it's looking awesome, can't wait to see where you go from here.

I have lost all interest in my SR build after seeing how big those intake ports are. I had no idea there was that much of a difference!
Do work man! Looking good! |
Let me know how you like your GTX turbo once its all running. I have been waiting for over a year now for my BW EFR turbo and will most likely be switching to a GTX series if it takes any longer hah

Anyway, more on the build... Once I finished with the sensor, I went on to making an aluminum bracket to mount my VVL solenoid block to the passenger strut tower. I wanted to hide the block as much as possible, so this was the final mounting location. I actually had to flip the bracket 180 because once the IACV was mounted on the underside of the manifold, it wouldn't allow the manifold to bolt up to the head. I ended up with an 1/8 gap between the IACV and the solenoid block when the IM is bolted into place. Then I ran the feed/purge lines to their respective ports. http://i627.photobucket.com/albums/t...g?t=1331512844 http://i627.photobucket.com/albums/t...g?t=1331512790 http://i627.photobucket.com/albums/t...g?t=1331512802 I think around the beginning of the year I had my manifold and turbo ex. housing sent to Zfever so they could get it thermal coated for me. I went and picked it up two weeks later on my way to a dyno meet in Tampa. http://i627.photobucket.com/albums/t...g?t=1327283683 http://i627.photobucket.com/albums/t...g?t=1327283688 As plenty of us know, when you remove the condenser from an s-chassis it leaves a huge void on the sides of the radiator. So, with a little time I had available, I made some airdams for the sides of the radiator. It's 1/8 aluminum, we have an abundance of it at work, so I cut what I needed. Air obviously travels in the path of least resistance, so leaving those holes unattended would've lowered my cooling efficieny and SR's have a tendancy to run hot, so this was a little bit of insurance. I will be sealing the tighter areas with some weather stripping, however this alone is a cheap and effective mod and will serve it's purpose. Dont mind the bent fins, I'll be straightening the majority of them out. I've had this radiator since 06' and it's treated me well. The hole in the second picture is for my oil cooler lines. I plan to have my cooler mounted right behind the grill. More on that later. http://i627.photobucket.com/albums/t...g?t=1331512811 http://i627.photobucket.com/albums/t...g?t=1332464084 http://i627.photobucket.com/albums/t...g?t=1331512825 http://i627.photobucket.com/albums/t...g?t=1331512829 I converted my old atmospheric oil catch can into a vacuum sourced catch can. I'll be utilizing an exhaust venturi for the vacuum source, which stills needs tobe installed into my down pipe. Making the lines and lines completed below... http://i627.photobucket.com/albums/t...g?t=1331512853 http://i627.photobucket.com/albums/t...g?t=1332464074 Oil cooler lines thus far. I need to purchase some more line to finish the run from the thermostat to the cooler itself. http://i627.photobucket.com/albums/t...g?t=1332464860 http://i627.photobucket.com/albums/t...g?t=1332464125 And my throttle cable that is hidden until it pokes out to land in the bracket. http://i627.photobucket.com/albums/t...g?t=1332464106 At this point I've begun to slow down on the build. A lot of little things that are getting put together, but they aren't interesting. I've also started the relocation of the fuse/relay box and I'll get pictures of it when it's mounted. It's a very tedious task doing the wiring, a lot of patience is needed. Sometimes I swear I have tourette's and scream obscenities when I screw up or get lost. Thanks for looking, still pluggin away at her. I'll leave it with a current status picture of the engine bay. http://i627.photobucket.com/albums/t...g?t=1337118640 http://i627.photobucket.com/albums/t...g?t=1337118631 http://i627.photobucket.com/albums/t...g?t=1337118630 |
VVL for life. What cams are you running again? Stock 2.0? or the N1's?
Never mind I see stock. Did you mod your exhaust manifold yet? If it's a DE flange on it the ports don't line up. The manifold needs to go up a little and it will be golden. |
Quote:
I already took care of the manifold issue. Oblonged the bolt holes then used a borescope to make sure Cyl 1&4 were up high enough. Then I torqued it down... |
This is amazing so far! Subscribed for sure! :)
|
I subscribed too, very beautiful worksmanship, pure art. I hope mine comes together like this.
|
cool project
|
JR, this thing looks like it's going to be a beast. I'll be looking forward to your updates.
|
Man, this looks awesome- great job! The pics of you sanding the bay made me cringe... I for sure do NOT miss that! I'm sure you don't either, haha.
