So it’s 11:40 and I’ve been at it again since 8:30.

I had an idea from the last time I had the carb apart that the power valve was really stiff and would flip between on and off rather than being progressive.

I reseated the diaphragm after reading an overhaul instruction and also removed two preload spacers from it. I figure once boost is…[Read more]

so i got stuck into it last night, was up till 3am…

 

pulled the carb off, and completely stripped it down. bored out the throttle shaft and pressed in some brass tube and carby cleaned it and put it all back together.

 

still struggling to get it to idle under 1000rpm but its smooth now, not misfiring and carrying on. i think the throttle…[Read more]

ha if only it was my own work! both the dump and the manifold came off ebay.

Had the carb fully apart last night and today. swapped the air bleed bits, and put a smaller 125 in place of the 135 in the primary. and now its much better to drive and smoother, bar being a bit rough on idle. and not being able to idle below 1100. i can drop it down…[Read more]

getting ready to work out what needs to be chopped or changed to make a FWD manifold fit my RWD layout.

 

pretty much just going to cut the main flange off, flip it over and go high mount and hope it physically fits.

 

3″ dump fits nicely.

 

 

 

My first of many silicone joiners arrived today, so fitted it up. 3″-2.25″ 90deg elbow. Off the carb hat then facing down into the first part of piping to cross over the gearbox towards the turbo.

 

Exhaust has a new tone to it since fitting the new carb and tuning it right, I quite like it. Has a strange subdued rasp to it but without being…[Read more]

Got my h4 LEDs today. Fitted tonight. Massive improvement in light output.  Very clean clear light too. Went from Phillips crystal vision bulbs which despite being “blue” were still quite yellow and now I have crisp white beams.  Very nice

 

 

 

Low beam, camera doesn’t do it justice of course

 

 

High beam

 

 

And while I h…[Read more]

The turbo is a Gt2871 which is apparently the upgrade size to a Silvia Sr20 type motor. Hoping I haven’t oversized ha,  considering the turbo I was planning to use was only a t25 off a diesel. Much tiny…

 

Updates will happen.  I want this done asap! Next work will be done in a couple weeks or so.  Thinking fuel system next.

Threw on some different rims n tires today,  the muddies will return when we finally work out what to do regarding a potential 4wd conversion.

I’d love to say yes put it there!  But no it’s a bit big

 

 

Rear mount advantages are as you say regarding no intercooler,  but sizing is super important to make use of the flow rather than heat energy the manifold produces.

Thru the cab would be “cool” (pun intended)  especially if you ran aircon inside!  Maybe some finned piping to hel…[Read more]

Yeh pretty much.

 

In theory you could run a stand alone oiling setup for the turbo. Have a mini sump and oil pump cycling oil through the bearings but would need cooling and to be changed frequently I’d imagine.

 

Good topic of conversation there

Turbo oil relies on gravity to drain away,  so to have it level with or below the oil level in sump requires a collection point and then an oil pump to return it to the motor. Otherwise it backs up in the bearing and can blow seals. Usually shows up as smokey exhaust as it burns the oil

Would be massively easier to mount it low and rearwards but then I’d need oil scavenging bits.  So as long as it phyically fits as high mount I should be ok.

 

Going to run water to air intercooler so a small barrel will get mounted low and rearwards.  Haven’t decided exactly how or where it will go but I’ve got some ideas.

Heat exchanger w…[Read more]

Had a quick look at turbo position while I was in the bay.

Going to have space issues low mounting it so plan is to either mod or recreate the exhaust manifold and make it high mount instead.

 

Took it for a drive today. Much better power delivery in the low to midrange revs, drops off at 5krpm where before it would pull right to 6k but I’m ok with that for now. Lower rev power has improved alot.  And idles so much smoother than it did.

Simplified alot of the vacuum system.

things happened.

 

 

 

 

 

 

it just fits.

 

 

 

 

modified linkage using stock rocker welded to the holley’s one.

 

 

 

and the best bit.

 

it runs!

 

todays job entails pulling the rocker off and painting it up all pretty in black wrinkle…[Read more]
