Yeha, speak for yourself.

I have put several hundred miles on mine just this past week along breaking it all in. I also took it to it's first track outing at the Refrigerator Bowl At Summit Point raceway in WVA. Car did well! Plenty of grip, temps kept in check and overall, no "funny" noises. The items that experienced "issues" were not related to the engine. The car also did several "hot laps" At summit main.

So far, the only issue experiences
1) Shifter popped out of the hard nylon bucket *easy fix)
2) PS system is getting over pressurized (easy fix. I havethe Taarks relocator)
3) One of the exhaust mount bolts fell out

Car drove on and off the trailer when I got home.

So far so good! This thing is a riot! I am now debating plopping in my N1 cams for good measure to keep the boost down and power sustained.

lol i'm just teasing, mine has been sitting on an engine stand for a few years now.

how is your PS system getting overpressurized? why will relocating it with the Taarks kit fix that?

[RalliartRsX]

Get that shit running!

The reservoir is mounting too much in line with the PS pump (I have my VET mounted in a Z32 chassis, and my dumbass got rid of the PS hardline which would have made my life much easier...….ughhh). So the pump is unable to push the air pockets up to the reservoir where it can properly bleed. This in turns causes air pockets to be trapped in the system and end up pressurizing the system. For short runs it's good. However, when I went to the big boy track and did a number of laps, the issue became apparent . My bro thought it was a coolant leak, however on further inspection, the reservoir was bleeding out.
Atleast, that's what I think is happening.
That or the reservoir I have is shit hahahahah!

I just got the Taarks Cam signal kit, the one that replaces the CAS, no trigger wheel here.

If I find we see timing scatter in the upper rev's I'll add a trigger wheel to my balancer (ATI).

[S13VE]

Oh and yeah, my engine has barely progressed. Block has passed inspection, Crank is being crack tested as we speak.

Thinking I might put that engine in a new shell given how much oither stuff I need to upgrade to make use of it. In the mean time, I might refresh the old engine in the current car so I can do another season while I wait.

Been following the Def model; just get seat time in whatever I can. I will slowly build it up over stages to get as much seat time as possible. A fast reliable car is a car that's not in a constant state of flux/build

Word - it's too easy to just "build" and never drive. It frequently turns into parts hoarding and never really working on the car because your goal line moves over time, usually farther out than any progress you've made. I'm guilty of it too, with trying to fit "one more thing" in while taking something apart, but that usually works better from an efficiency of work standpoint.


I say this with not having tracked the SW20 due to kids taking up all my time. I could go to the track, just tough to swing that much time in a row.

Amen.

So yeah, trying to figure out how much of a "refresh" the car gets because I can't keep tracking it as is, comp is starting to drop a little on one cylinder, breathing a bit more, oil surge more often in corners due to going faster. This is my old CA18.

Hard to not want to do a basic rebuild if I remove the sump for breathing/oil mods - maybe just a spool kit, throw a 2860 on it and aim for a few extra kW, as much as the 460s will allow lol Maybe 220rwkw?

Annnnnd I've dropped another few grand on it if I do that...

Excellent !! How many whp do you have in this configuration? You use 87mm forging pistons on stock sleeve . Because I still wonder if I should put on shirts to have 550 whp with my 87mm hks stroker kit and VE p11 head

[RalliartRsX]

Errr, no idea! Discovered a litany of issues from the last dyno. One major one is the complete collapse of the CAT. EFR 7163 on 14-16psi. I have seen a dyno on a 2 liter VE with a EFR 7163 on the "gram" that made about 330 WHP on a mustang on the same boost (I have a similar setup). But I may be just shy of that as it has no timing in it. Just straight AF correction and that's it. Still on pump. Spins 305-30-18 ATR Sport II below 48 F in 3rd if I am not careful (JK41 6 speed).. However, they are absolute shit tires (compound sucks!) and I had much more grip on a set of 255 Zestino Grudge R (hard compound). So terrible comparison lol!

86.5 bottom end. Torque plate used for boring/honing. To answer your question; full send on 87mm HKS stroker kit. I do not forsee an issue at your power level. However, this is indeed the internet and YMMV

[peglio]

No relevance to the chat but I finally got my engine back and in the bay [emoji1591][emoji1] now just got to build the rest of the car ha ha

Nice.

Who here is running drive by wire?

Thanks man . I will be , just working out what I’m going to run atm

great, i'm going to try i think in 87mm, with good egt control to be safe. For the bottom engine did you get ARP stud? because I see a lot of people installing ticket main cap or plazamaman girld, useful or not? for our power

What engine mounts are you guys running? Specifically for the ones running the P12 CAS at the rear of the head? I have the ISR mounts and they make everything rattle, tolerable but it sucks. I was going to run the Nismo mounts but had read that it raises the motor enough where the CAS would not clear and hit the firewall lip.
Any input would be much appreciated.
Thank you

[RalliartRsX]

drift freaq mounts. He is on the forum

This was with an EFR 7163 twin scroll.


The N1 cams are similar to a stock F20C/F22C cam profile (S2000), and those things love boost too.

Honestly, with the N1s, you need a pretty big turbo. A 7163 is the smallest I'd go with. In the EFR world, I wondered what a 7670 would do. Probably still pretty strong response and even more nuts top end. That said, even the 7163 made so much power it was getting a little hard to manage at ~18 psi+(1.2 bar+).

The sound on the big cam is worth the N1s alone.

Hey Def, I've been out of the 240sx game for a little due to life events but I'm finally planning on getting the whole VET/7163/CD009 build on the road again this spring. Just wondering where you wound up with yours since our builds are really similar.

My notes say I got 404whp at 20psi but I hadn't printed that dyno sheet so I don't recall the torque. Last pull I had printed out was 384whp/327ftlbs at 20psi. Spark started blowing out, things were getting real hot on the steady state dyno and I stopped my session. Have since installed the IGN1A coils but haven't made it back to the dyno. Torque was leveling off around 3900 and pretty flat till 7k (all I pushed it to with the blowouts).
Edit: Found an old post with the full numbers, 404whp and 338ftlbs at 20psi and 6500rpm. Clearly a lot more HP waiting to be had at the same boost just by revving it to 8K+.

[e1_griego]

He sold the car and is messing with an mr2 these days.

[LuckyX2]

Yeah, I just came back to the post to edit it haha, I saw turtle's post about the head failure and also found Def's MR2 build when I googled for "SR20VET 7163" hah.

Man, I've been out of it for too long, things have changed.

[RalliartRsX]

Well, NRR is officially dead. The domain has not been updated so this is the only place with any inkling of long standing knowledge for a VET swap

And even then, it pales in comparison to NRR

[turtl631]

Indeed, bummer. Everyone is hyped on K swaps now.

I broke the engine. Just got a rebuilt Mazworx head and block. Trying to get it together here soon. Just planning modest pump gas fun for now to hit a few track days. The car has been mostly broken since I bought it in 2017. Having 2 kids since then doesn't help. I just track my daily M3 and the S13 sits sad. Need to either use it or move it along. I'll toss up some updates once I make progress. Setup is basically the same as Def had.

[LuckyX2]

Oh no, NRR was a great resource
I take it nobody was able to do a dump of the site before it went down?

And K swaps in 240s? What world did I come back to haha.
Looking forward to your updates, I'll do the same.

Lucky, what part of Philly are you in? I’m local and should have my car up here in the next couple of months. Is your car street legal? If so what steps did you have to take in order to get it inspected? I’m coming from Fla and there were no inspections or emissions down there.
