Real St. is having a huge black friday sale all weekend long. So took the opportunity to pickup a set of Kelford VVTI 202-C cams (similar cam card specs to GSC S1). Almost bought an adjustable cam gear too for degreeing the exhaust cam, but decided against it. Like $98 for a BC or Tomei one, not bad, but decided not to.
Well latest purchase. Wise choice, probably not. But I have been so excited to try one of these so I just said Eff it since Geoff @ Full Race gave me a really good deal on it.
This is a new Borg Warner SXE-300 8776. So it's the 64.5mm comp wheel, which can be paired with either the larger (73mm) or smaller (67mm) turbine wheel. I went with the smaller turbine as its actually very similar in size to my current turbine wheel. And if you think of it in PTE terms, this turbo would be called a 6467, so from that perspective it seems like a pretty good combo to me. Plan will be to reuse my current .91AR T4TS turbine housing, but I may switch to a 1.0 T4TS just to see if I'm choking it out.
Geoff said he expects it should spool very similar to my current SX300 8475 (61mm) but obviously have some top end gains.
Plan is to keep the current SX on the car and get it tuned on a good amount of boost (30ish). Run that for a little bit, then maybe in late summer swap this on, and see what kind of difference it makes. And hopefully some dyno sheets to show the difference.
It came packaged very nicely. And just in case I thought this was a big single, they remind you on the box that it is in fact NOT, it is actually a small turbo, make no mistake about it!
Damn, that looks remarkably close to the turbo my brother just picked up for his rx7. Borgwarner but I can't remember model specifics. Looks like a "bigger" turbo to me lol. Looks nice.
You are gonna love that turbo. Personally been really enjoying the Borg efr 7670 I installed on the fd this fall. Spool is so early compared to what I am used!
Car starts and idles like a champ. Had my 3rd brief remote tuning session with Vlad. We are about as far as we can take it now until I get my flex fuel sensor plumbed and wired. But I'm just happy this thing starts and idles cleaner than it ever has since ditching the stock ECU. Already feeling good about my choice to switch over from the MS3 headache!
So I had a second tuning session with Vlad. For this session I drained as much e85 out as I could and filled it with 4gal of pump. And I also installed my flex sensor. These 2150 injectors on pump, combined with no idle motor what-so-ever, was tricky to get to idle nicely, but he did it. Doesn't idle as nice on pump, but not bad, and doesn't really matter anyway since it'll have e85 in it 99.999% of the time.
So the car starts and idles better than ever. So I started buttoning things up and got the car on the ground off jack-stands for the first time in over a year. Pulled it out of the garage. First time she's seen daylight since 2015 Fall Proving Grounds! She's dirty but not too worried about that yet.
I drove it just around my little neighborhood area, and everything appears to be working perfectly! I took a couple logs for Vlad (low/med throttle stuff). He'll update my tune to reflect, and I think we'll be doing a few rounds of back n forth until we're happy.
