My S13 VH45DET build thread

[b20vtechb]

well i started by finding a motor and 300zx trans on craigslist for 500$ and picked that up, was just planing on changing guides and calling it a day but as soon as i pulled the valve covers off, i knew that wasn't gonna happen. the motor was super nasty with sludge that was damn near rock hard like a crust. so i ripped it all apart and sent it down the the machine shop, for a hone, deck, cleaning and valve job.

i have no before pictures but the machine shop guy said it was the nastyiest motor head ever seen lol

currently i'm waiting on my bearings to show up so i can begin assembly






























still have alot of cleanup to do but until i get bearings i'm kinda at a stopping point except for all the cleaning!

Post some more pics. What are your specs of the build? My bro and I are doing vh swaps as well, I've been tossing up either going procharger or single turbo with my vert, starting to lean towards single turbo again.

[b20vtechb]

well its just a stock rebuild. i just had to clean alot of parts up.

[b20vtechb]

got the powersteering pump figured out and cleaned up. i'm using an sr20det PS pump with the vh45de's brackets and they all bolt right up expect for one hole witch i dont think will matter. painted the brackets and pulley with black wrinkle paint.







i also painted my oil pan with spray on truck bed liner




more to come tomorrow when i pick up my cylinder heads

[b20vtechb]

well still waiting on my heads to get done, but i did get my mount kit and driveshaft in, and finshed cleaning up my crankshaft.

Polished and deburred crankshaft





Mount kit from Xcessive



VG-S13 driveshaft from Xcessive




Oil pump disassembled ,cleaned and polished the rotors



Timing chain kit

Looks like it's going to be a quality build! Where did you get your timing kit from? I'm in the market now.

250$ pretty good deal i think!

[hannibal]

I'm assuming the SR20 PS pump with VH bracket clears the frame rail. I'd like to see a pic once the engine's mounted. Sound like a good solution.

block after the final clean








Crank installed after a final clean of the block and crank, getting all those plugs out of the oil galleys was a pain in the a**. had to drill out 4/5.







i should have the heads this week, and hopefully have the long block assembled by the end of the weekend

[b20vtechb]

got 6/8 of the pistons/rods installed, and painted the front cover.









got 1 more piston left to polish. and still waiting on my heads

[b20vtechb]

got the rest of the pistons installed and the windage tray and oil pickup put on

[b20vtechb]

picked up my heads today. and they look very good!











The machine shop had some difficulty removing 3 of the HLA's and had to do this to get them out of the head.



so i had some sr20det HLA's laying around and noticed they were very similar except for the grove and the top portions


vh on left sr20 on the right


vh45de on the left sr20det on the right

so i pulled the extra sr20det hla's apart to see if the 3 vh45 hla tops would fit into the sr20 hla lower


sr20 on left vh45 on right, notice the slight height difference and the profile of the ball on the top is a little bit different too.

You're doing an awesome job on this engine. Everything is clean! Too bad it won't stay that way for long.

While you have the front timing cover and oil pump off, is there any way you could remind me how the oil passages work? Even some pictures would be great. I'm trying to remove the factory oil pump but feed the factory oil galleys. From what I can remember and looking at FSM diagrams, it looks like the oil gets sucked up by the oil pump, out into the oil tree (which port is in/out (left or right?)), BACK through the pump, and into the main galleys for the block. How does oil get from the oil filter to the galleys? Does the OEM pump have to be there? It's been so long since I put mine together I'd really appreciate some help if you have a few minutes.

Looks smooth! The motor is very pretty. Kinda whatyou'd want to see when you pop the hood.

lol yeah didn't have anywhere else to do it.. plus helps keep it all clean.!

got the motor dropped in. haven't centered it or leveled it yet but mainly just looking at clearances.
but it does look damn good in there!

[b20vtechb]

ok got one of my fuel rails done.

[b20vtechb]

well project has kinda been on hold due to winter and having nowhere to work on it but i've been saving up some money and planing out some stuff. got my oil cooler in the other day its got 12an fittings and is tube and fine design plus its nice and big. so i shouldnt have any oil temp issues. heres a couple pics for now and hopefully i can get my injectors ordered in a week or 2 and do a test fire on the motor.

[klh6686]

awesome work on the fuel rails man!

[driftrkp]

[b20vtechb]

Holset HX52 with the MFS billet wheel

[driftrkp]

thank you. i been trying to find witch holset would work best on my vh with no luck i was thinking hx40 but they look to be a liitle to small and i can get two hx35's so i thought about twins but think they mite be alittle two big?

[nelson8708]

little inspiration for ya glenn....This guy has a build on ka-t.org, he plans on taking it up to 8,500rpm so he has a useful power band. I believe he's only on 15psi on this run
