Worth tuning R33 Series 2

Recently purchased my R33 Series 2. It has "120,xxxkm" probably double that. 

I want to tune my car to 250-280rwkw. But I have been warned being a 20 year old engine and unknown previous condition it is not worth the cost. 

It will cost about $8k to tune it to this power level. 

What should I be looking out for and is 280 rwkw considered "safe" should I be looking at the gearbox for issues with this power level especially the clutch I'm guessing?

Right now car is stock running 7psi.

Plenty of people making more than 300kw with unopened engine and stock gearbox. Is it "safe"? No telling - up to you if you want to take the risk but do a compression test and service. You willl as stated need a new clutch sooner rather than later.

Yep. Do a compression test. If it passes ok and has consistently cy between cylinders then start tuning. Stock internal R33 RB25DET is one of the best bang for buck tuning engines you can get.

 

Gearbox will be fine but throw some new oil in. Flush the coolant, get a good radiator, keep the stock shroud. Flush the oil with diesel oil (not fuel) and put some good oil in. Then proceed.

      If it's for a SR20, make sure it's not the American Poncams, might as well call them Poocams. Had a set in a friend's car, all scuffed up after a few track days. Like the metallurgy Tomei USA used is junk. Went back to JDM OG Tomei Poncams, no issues till now.   Tomei USA is not the real OG Tomei.   Random rant over, fk the US of A, bunch of c u n t s.

      Most of the industry in North America either runs on Siemens or Allen Bradley. I have two redundant S7-1500's on my desk right next to me for simulation. Siemens has been losing ground though since Stuxnet, as cybersecurity is a big thing. In my line of work that is federally regulated, you must by law have a cybersecurity management program in place and its audited and inspected every so often.  I work with Emerson PLC's daily (RX3i's) and have done large biogas/refinery projects with their DCS's. Their PLC's are somewhat OK minus the way they do PLC redundancy (You have to download on both PLC's separately every time you make a change )  As for their DCS's... you'll be limited financially first before anything else stops you. Costs are exorbiant at roughly 10x what it would cost you to do with any other system (e.g AB PAC).  1990's, those suckers are brand new haha! Kraft-Heinz (An old client when I use to work for an ESP) still runs Siemens TI505 PLC's from the mid 80's. Ohh how I don't miss working with those... you could only do a certain number of online downloads until it's "Change" buffer would be full and you would then need to go offline to do a full download. There was no warning of when this was coming up and it generally would happen when you would go in at 2am to make changes before production -_-.

      Unfortunately, not only is that not the case, one of the main "Selling points" of safety over comms is they clearly state in writing that there's no need to segregate safety networks from non-safety networks. It always gets intermingled with everything else on an ICS/OT network.

      SR20 to cefiro

      By KKaplumbaa · Posted

      Hello. I have an a31 cefiro but since I am in Turkey we have a CA20S engine. I did some research. Then I found that I can swap with a ca18 but when I heard that it has the similar substructure as the s13. I thought I can swap with an sr20 because the sr20 was used with the s13. So can I easily swap the sr20 on my cefiro or is it difficult?
