The Sr20/Sr22vet thread

[RalliartRsX]

Good news is the leak was coming from one of the oil lines. All fixed up. Boost leaks located and all set. Warmed it up a few times, etc. So far so good.

[S13VE]

Excellent news.

Good luck next week/week after.

Can anybody with an s13 measure the distance from their head to the strut tower on the intake manifold side for me? Fabricator wants to know for plenum clearance and I don’t have an engine in the car quite yet. Would be a huge help!

shut up and buy my mazworx manifold

slap a tape measure across that bad boy and let me know what you got

TBH I would have just bought a plazmaman manifold if I knew this guy was going to take 8 months to put this manifold together, but Ive already invested the money and need to see it through

[RalliartRsX]

Same guy who did JP's mani??

PM me on who you went with for your block.

Yep, Kyle Nardi. Kid does good work, just really hard to actually get him to do the work. Heard that from a lot of people, not just my experience. Doesnt help that hes had a lot of personal struggles throughout the last year or so but thats neither here nor there.

no prob, ill measure it this evening

What has everyone done for their catch can/PCV routing? p12 valve cover

Finally have an engine in my car and Im excited to start getting into the little details

[RalliartRsX]

Run the PCV port and back port to catch can. Keep the block ventilation. Run catch can to either a vacuum source (turbo inlet) or open.

Done.

[d9m13n]

Block ventilation meaning back right hose connection on the block to the back right fitting on valve cover?

[RalliartRsX]

Yep. The one on the driver's side by the firewall/exhaust/downpipe. Keep that line in place. Vent the rest of the valve cover to whatever you see fit.

[d9m13n]

Thanks! Easy enough. Are most people keeping the stock pcv valve or just replacing with a straight fitting?

[RalliartRsX]

Replacing with a straight fitting. Keep the PCV if routing to the intake (manifold). The only reason the PCV is there is to not allow boost back into valve cover causing all sorts of issues (like increased crankcase and under valve cover pressure for instance) and to allow only vacuum to work on help pulling the crank case pressure and oil vapor and allow the baffles in the valve cover to take care of it.

Now that you mentioned straight fitting, what kind of fitting exactly. Tap the valve cover for an AN screw on fitting? I'm wondering if there is another type of fitting that'll work that does not involve removing my valve cover. lol

taarks makes a block off fitting. you could always take something like this and drill/tap it for whatever breather line you like, rather than remove your valve cover for welding

[d9m13n]

P12 VC pcv fittings are screw in if I’m not mistaken, but I’m not sure what the threads are. I’ll try to find out if nobody knows offhand. Would make it much much easier to get an adapter rather than welding/pressing/tapping etc.

Edit: I’m only referring to the pcv fitting being screw in. The regular hose end fittings on the right side and rear of the VC are press fit

[mewantkouki]

^ No they aren’t. They use a plastic PCV valve that’s a press fit with a rubber grommet like an s14 / s14 vc.

You’re right. I saw p12 pcv valves with threads after a quick search, not realizing they’re for p12s with the qr20 not the sr.

Hello everyone, your page makes me dream, I am thinking to buy head sr20ve, I currently have a sr20det redtop, with head hs, because of a pusher, the head sr20ve on a sr20det and reliable ? I see video or shims jumps ? because my goal and 550whp for drift , max 8000rpm ( stock springs ?)


thank you for the support!

thank you for the support!

there are a number of people who do have issues with shims spitting out. some people are machining custom valve stem caps to resolve the issue, other people are using shimless valves to solve the issue.

VE head does have many advantages over normal sr20 head, but it is NOT cheap.

[PRT73]

Thank you for the answer !!! Interressing as a solution, do you have any links as I look at the machined shims?

I don't have any links, one of the local machinists around here is working on producing them, but he's not a large business or anything. I'll try to get some photos if I can.

[PRT73]

Thank you because here in France no information I would be the only one

you may want to contact BS Bildeler, I believe they're in Norway or Sweden? they built a crazy sr20vet a few years ago

I'm running custom valves, the top of the valve stems are machined. the valves are just longer, tips are longer then machined to OE spec clearances. so in term the shims are tossed out.

interresed , you have picture ? and the price for the setup ? thanks you

your machine shop has to do all the measuring and machining to set the proper lash for your head. the big issue is, if you machine too much off, you have to replace the valve, you can't really add length back on to it.

[d9m13n]

If there's anybody whos been lurking this thread and wanted to start building an sr20vet, all the parts from my old setup are now for sale and Ill make a killer package deal if someone wants to take everything Stout 500whp shortblock that just needs machining and assembly!
