Apologies for the thread bump, another year has passed since the last post, hopefully 2023 will have more updates.
As always, the daily driver gets more attention and the R34 gets neglected. The Colt CZT was sold last August and I purchased an MX5 NC1 Sport. From October 2021 > October 2022 I had only driven the Skyline 1000 miles
I'm due to get married in April and have been holding out spending any money on mods for the MX5 till after the big day. Rather than doing that I promised myself I'd drive the Skyline more and sort out a couple of minor things on it.
I usually wait until March/April to put it back on the road, but the UK weather had been dry and the roads reasonably salt free. So with that, I decided to tax the car, give it a clean and blow off the cob webs (litually).
I remember driving the car last year and hearing a whistle/whine on acceleration aswell as a struggle to build boost. I did a smoke test and there were no leaks. I also did a vacuum pressure test on the actuator and it held pressure no problems.
I removed the intake hose to check the play to find it does have about 1mm in-out play, the same amount the last time I checked (April 2020) Not ideal!
With the car back together I took it for a test drive and it all seemed fine. The Greddy Profec OLED boost controller was set to my low boost setting (7-8psi) and it built up boost with no issues. The whistle/whine noise had disappeared too, strange. I also blanked the blow off valve to see if that eliminated any issues, but it drove the same.
I made a video for my Youtube which goes into more detail of getting to the turbo etc including some in-car footage of me driving.
I purchased a used turbo with the intention to send it away to be rebuilt, easier said than done. I contacted the first 1.5 pages of a Google search and not a single company can do a standard rebuild on this turbo, only a Hybrid rebuild.
Not wanting to constantly buy used turbos to get by, I started to crunch the numbers on what was required to go the hybrid route. The kick in the teeth was having everything previously purchased but it all got sold to pay off debt
The cambelt is due this summer as it'll be 5 years since it was last done. The clutch will also need replacing because I don't have any history or evidence of what it currently has. I don't want to go through all of this effort and it slips on the dyno.
I've spoke to a local tuner (J's Garage, whos very very familiar with RBs) and he's advised on what needs doing.
Hybrid Turbo rated to 450hp (AutoExtreme)
Fitting Kit braided lines, genuine gasket set (AutoExtreme)
Xtreme Heavy Duty Clutch & Lightened Flywheel
J's Garage Trigger Kit
Injector flow test & fitting
Fitting and Mapping
Tie rods/track rod ends/wheel alightment needed too
With a geniune cambelt kit/waterpump the total for the whole lot comes to around £6800 GBP / $8k USD / $12k AUD
Which means the MX5 will be up for sale in the coming months to help pay for it.
