Thread: VVL for drifting S14 with a 4.6 Rear***BUILDING NOW***

I am watching your build with great interest as well.



I am curious about this too.

A local shop will make a header for it to get the maximum flow out of it. It's going to be pricey to do, but I am positive it'll be beat the ASP header for FWD in HP gains. The intake manifold is up in the air really, I checked the ports on the factory S14 and they seem really small IMO, so I will ask my shop to see if they would rather make an adapter flange so that the ports from the upper portion will mate to the lower portion of if they'd rather see the results of the XD manifold that people use that bolts onto the lower manifold for the VE head. Either way I got all the sensors I would need from the manifold and that was my main goal in getting it since for the first try it'll be using just a stock ECU chipped just to get a baseline of how a factory ECU does on my setup. Right now I am just focused on getting it running similar to that of a FWD Sr20VE.

...UPDATES!!!! Machine work all done for block and head. I had the best shop that I know of for cylinder head work do a radius cut valve job on the head, meaning no more angles, just a single radius to have the best air flow like a veolicity stack, also on the S14 SR20DET block I had them block off some oil drains and also the VCT port. Going on thursday to get everything, and assembling the bottom end on thursday. SUPER EXCITED!!!



Huge thanks to Greg at Gspec.com, and Mad Brad at Enginelogics for the machine work. Thursday when I go to pick up the block and head I will talk to them about the intake manifold design they have thought up. The shop has been focused lately on NA stroker builds, so they're really excited to add another project to their book. Toyota 2.3L 3SGE stroker with a GENIII 3SGTE head and a 2.2L 5SFE bottom end with larger bore pistons is what they're tuning now with ITBs... Regaurdless, just thought I'd post up the bits and pieces that are the most critical to get.

What are some of the differences with the S14 SR20 short block vs the S13? other than the VCT oil feed?

There is a passage on the back on the block that is larger for an oil return port for some reason, but it's not there on any S13 or VE block. I brought them a factory VE headgasket as well as a cometic one, and neither one had this large oil return port. I chose the S14 block since it was an NA engine and cylinder walls were in better shape, and it was priced good. I have yet to find an S13 NA block being parted out, but I have access to another S14 SR20DET block which I will probably do a turbo stroker build on for next year.

First off who shipps a block in something like that? Who ever did the shipping does not care. I shipp blocks in boxes with so much packing around them. People who ship transmissions and blocks in these rubber tubs will only bring trouble to them selves.

As far as getting a perfect block, I have 6 perfect VE blocks that have come from motors that were in perfect condition when taken apart. I part out motors so the blocks that I sell are from 100% working motors

Yep, it was some "shop" in AZ that kaotekxe knows of. Regaurdless, this is only the first attempt at this engine setup I have done, next one will be big bore. Also finding a good RWD Sr block is near impossible since almost all 240 engines either get blown up, melted pistons, or are just plain worn out.

UPDATES.... AS PROMISED!!!

Just set my work area up again. I have 2 other DET engines I need to put heads on, and then a 3rd block I need to decide what to do with.

This is my first radius cut valve job on an SR20 head I have paid for. Needless to say, it was not cheap, but just a little more than a standard valve job. No more angles

This is a picture of an S14 oil drain port that needs to be blocked off, S13 SR20s do not have this port. It's rather large.

Also another port only on S14s that needed to be blocked off. VCT oil feed port

And the shot of the S14 block...


Tomorrow night I will clean up the cylinders, install the crank and make sure it's good, then possibly might throw pistons in. My machine shop had to take a lot off the block, but I can stil see the piston grade stamp for each cylinder. I'll have to measure some stuff once it's assembled to see the clearances, if need be I'll order another gasket and combine the inner pieces to the right thickness. Well hope this gets peoples attention now... Like I said, this is supposed to be a quick build. Open to all suggestions on parts, but I have my own assembly methods and they seem to be doing just fine on all the SRs I have done, even my crappy daily driven G20 that had been rebuilt twice by previous owner and then I threw in a new crank 10K ago, never had to open her up again.

I talked to my tuner and he will be building a specific plenum that will be better than XD RWD conversion, and also will provide more midrange TQ gains, not just peak power. They have flow bench in house and I am still looking for another VVL head folks so they can play around with stuff so I won't be wasting $400 heads. ANYONE HAS A JUNKED HEAD, dropped valves, etc.?

Looks good. Can't wait to see it in the car.

Shortblock done!!!! Crank turned silky smooth, just like I like it. This week I'll see the piston to valve clearance I have now due to machining, and then see what kind of cams I can run. I always do a very light hone on cylinder walls that have no ridges or damage, so it might look like its still smooth, but it's rough enough to seat piston rings. I used a 400 grit stone hone and only did about 6 passes pretty fast to remove the glaze. Assembly lube IMO does not give you the right feeling of how much force is needed to turn the crankshaft, so I alwa just use straight 30 weight no detergents or anything. Also going to get the lower oil pans cleaned out after I do a custom oil pick up. All bearings and rings are OEM and crankshaft has not been turned. I want to thank Gspec again for providing the bearings and small bits for this project. I have to place another order for some gaskets next week. Now that I have the short block done, I feel much better about the engine running very soon. I am borrowing an older chassis from a friend to test the motor out in and break everything in (S12 already drift ready and gutted), then going to throw it in the S14 chassis since the KA in there is still kicking good. Anyways, here is pic.
