Coda Posted April 16, 2016 Report Share Posted April 16, 2016 Never thought of the need to O-ring the throttle shafts, hopefully it's not a problem because many blow throughs didn't need this. The only ones that don't need it are the setups that encase the entire carb in a sealed box. Carbs that have been boost-prepped have sealed shafts. And sorry I am ignorant :lol: , but I have enough common sense and creativity/motivation to get this working. Common sense and creativity cannot replace knowledge. Please read some books. Learn your theory. Good luck. 4 Quote Link to comment
datsunfreak Posted April 16, 2016 Report Share Posted April 16, 2016 As as another "old man, been there done that" guy, you will very likely spend more money and make less power than a stock KA24E. ^_^ 5 Quote Link to comment
DAT510 Posted April 17, 2016 Report Share Posted April 17, 2016 Im sorry dude, everyone appreciates your motivation, but its all in vain since the parts you are making wont last you longer than 6 months, if the engine lasts that long. I know you wanna be the underdog really bad!! But slow down, read some literature, and do this the right way before it goes all up in flames. No one here is trying to steer you away from your goal much less trying to insult you, we care more about the 510 honestly. 1. How to hotrod and race your datsun 2. Street turbocharging 3. How to modify your Datsun OHC engine Great reads, after that youll have all the information necessary to build a kick ass and reliable 510, good luck Btw before you post a forsale add, please let me know 3 Quote Link to comment
That4doorKiD Posted May 24, 2016 Author Report Share Posted May 24, 2016 Gonna be boosted within 3 weeks :sleep: made my Turbo manifold finally, but I cheated...first time I've ever taken a part to a shop ever, I need to learn welding skills List Still goes on ACCEPTING donations* -30$ intercooler from my honda friends -Electric fuel pump 9-12PSI + Fuel P regulator $59.99 -Weld up the aluminum Bonnet-Hat $??.?? -Intercooler piping, I can probably improvise from parts -BOV HKS ebay $39.99 -1/4 NPT to 8 AN -8 AN to 10AN adapter -Air/Fuel gauge $15 -Boost Gauge $17 1 Quote Link to comment
DISLEXICDIME Posted May 24, 2016 Report Share Posted May 24, 2016 Put the carb in a box so you can use a intercooler 1 Quote Link to comment
MantisX620 Posted May 24, 2016 Report Share Posted May 24, 2016 Im cheering hard as hell over here man. Congrats on having the balls to try, knowing that you can ruin your engine. Wishing you much success. Waiting patiently for the video of this thing in action. Quote Link to comment
Stoney Posted May 25, 2016 Report Share Posted May 25, 2016 Credit to you mate if you do get it running, ignorance and motivation sometimes far outway being realistic. Solid advice already given to you by quite a few people, nothing here is worth not doing. Water injection setup on this would really help cool inlet (to stave off detonation) and lower exhaust gas temps (to keep that manifold alive) Seriously consider a wideband oxygen sensor, such a good investment, something any car guy should own, will pay for itself over and over, even if you save one motor from a rebuild its paid for itself. The biggest issue you will have will be tuning it, the stock carb setup won't work, and if it does, it won't be reliable at all. Source a carby that has been used and proven to work in a blow through setup, SU carbs are cheap and readily available, so are the webers. Slapping together a setup might work, but if you save that little extra, and use some quality parts, it will be a lot more reliable, a hell of a lot easier to tune, and a lot more enjoyable. 1 Quote Link to comment

mattyhacks71 Posted May 27, 2016 Report Share Posted May 27, 2016 Just let the guy do what he wants its his car. I'm so tired of the old farts on this site shooting down any idea that isn't a tried and true formula. Not everyone wants an l20b with a 32/36. You think hot rodders in the 60s had forums like this to look up the best power solutions and what fit together the easiest? No. They thought something would be cool, so they went and did it. If it doesn't work, oh well you've learned a lesson. 3 Quote Link to comment
TENDRIL Posted May 27, 2016 Report Share Posted May 27, 2016 i cannot argue with you matty, I agree with you in fact, however i was just chiming in only on the exhaust mani. which it sounds like he has taken care of :thumbup: Quote Link to comment

If it doesn't work, oh well you've learned a lesson. There's a lot of solid advice being given, from experience, not just heresy. A stock carb won't take boost as a blow through setup unless it's modified to suit, a stock fuel system won't work without a boost compensating regulator, generally thin steeled manifolds welded with a stick welder won't hold up to the heat that is produced from a turbo manifold. None of these suggestions are shooting down his ideas, people are just trying to help him not waste his time and get it right. 1 Quote Link to comment
That4doorKiD Posted June 8, 2016 Author Report Share Posted June 8, 2016 just need to buy my 32/36 Weber Hat to push my turbo through that bitch, and she'll live. I'll probably buy some plastic nitrophyl floats and get 135 jet. I just want this to run and then I'll start modding to more practical parts hehe. My $50 turbo had no reference numbers for parts or thread specs so I had to go to the hardware store for some couplings and npt adapters. :) I'm about to tac up my flange right now and position the turbo Quote Link to comment
That4doorKiD Posted June 8, 2016 Author Report Share Posted June 8, 2016 $30 front mount and some piping from my honda friends. most likely going to cut my valence for the piping :crying:\ Quote Link to comment

That4doorKiD Posted June 9, 2016 Author Report Share Posted June 9, 2016 Using my Dad's two door to reference my turbo position, and it fits so well!! Just needed to put a spacer and push the turbo out 2 inches out more for easy access, and clearance. I'll weld up that flange tomorrow and tah dah! Had some trouble with the oil return fittings being too long because i have like 3 adapters on there and it doesn't clear the block, so I need to look for 1/4 compression pipe thread tees or 1/4 npt thread tees any 90 degree i can find hehe. Yesterday, my goodies came in the mail! Electric fuel pump, and my regulator. Quote Link to comment
That4doorKiD Posted June 9, 2016 Author Report Share Posted June 9, 2016 FWIW, I have a fiberglass one already cut for that kind of intercooler... Can I get it o save my 68 valence from surgery? I can pay for shipping :hug: 1 Quote Link to comment

Haha wish that was an option for me but my Dad doesn't have any extras, we don't even have one for his 2 door and it's all dented up sadly And thanks a lot, that's some true datsun passion :lol: Quote Link to comment
datzenmike Posted June 9, 2016 Report Share Posted June 9, 2016 Lose your '75-'77 intake and get an earlier L16/18 or a later '78-'80 L20B one. They have coolant flow through the intake runners to cool them. Just drill holes in the head like on the gasket. That header is going to bake your intake. Heat is what causes pre ignition. Keep your inlet air as cool as possible. 2 Quote Link to comment
