[CA18Magic]

still lovin the car, this guy deserves some respect

check out my build if you want to, still in the restoration phase but i will start modding it hopefully within the next week or so. I finally bought my 240 after seeing your thread so thanks for the inspiration.

Haha, i'll definitely check it out. Good luck bro!

I liked the other wheels better.

Hey I got a quick question about your sparkplugs! what did you gap them at? does it seem to sputter at around 5000rpms? cuz i am about to pick up some new spark plugs so just wanted to make sure that these were flawless!

[HIGHFIV5]

Most people including myself gap them to 0.8MM.

spark plugs are not the only problem. look up a post about cut off sputter jump 5k rpm . it has something to do with the coilpacks arcing and not having good coverage. ie (paint pealing boots cracked.)

Hey when you changed the water pump did you have to take the timing belt off?

[Noxy]

When i did it i removed the timing belt, replaced the pump, then replaced the belt/idlers and such... Granted it wasn't on an RB so it may be different...

[jdm2191]

Real legit build! Planning on getting my RB20 this summer too & I cant wait!

[smitty41393]

So did you?

Oh, sorry.. Yes i did. But I kept the upper belt connected to the cam pulleys. How you might ask? lol I zip tied the belt to each cam pulley. 2 per cam towards the top so they wouldnt jump teeth. Trick my dad taught me... In the picture below I removed the cam sensor bracket of course...

[Lonismos14]

K this is going to be a bit tricky, but i think i will change the pump first then belt with idlers and tensioner. Thanx

[supersayianjim]

well thats a good idea. but i actually took off the belt(and i have to do it again because i used the stocker that came with it.) but i used a chalk. and i still can't get the timing line to line up again(alwell)

hey c18 progress yet??

Here's the bracket i made for my throttle cable


Ok, here are some pics of my gauges before and after wire consolidation (pictures are from cell phone) Soldered and heat shrinked


Mounted



Heres a vid of the gauges


Since i finally got the tach working and correct, i can accurately time this thing. Thinking about siphoning the gas out so I can get some premium in there. I have this whole weekend off so more to come.

[Lonismos14]

depending on how much/how old gas is in there i would just use some octane booster and fill up with 93 you will be fine.

[supersayianjim]

how does it run??

[CA18Magic]

how does it run??

Haha, SO nice! Boost starts at about 3k and pulls to almost redline. Super smooth, great power band. Sounds ammmmmaaaazing. Heres a small video. Still no tabs, and couple more tweaks here and there. But almost ready! Also wired my lights up! Low/hi beam come from single h4 bulb, and the inner bulbs (fogs, as listed on zilvia) comes on with high beam. Turn signals/running lights on bumper and corner lights as running lights for now.
Sorry, camera phone pic again

And for the video! IN and drive by video. Keep in mind road wasnt completely dry and was kinda cold out. No WOT in this vid

[Lonismos14]

Nice, so your car isnt stumbling without the bov recirculated?

[CA18Magic]

I was surprised myself, but no it doesnt! Haha, venting out with no bogging issues is awesome lol

[Lonismos14]

Watch it be my luck, when i install my greddy i have problems.

[IBoughtAS13]

Did you do refreshing of the timing area? Belts, water pump, pulleys? Where did you get the engine from? I have been reading about Jarco and heard good and bad things over at Tampa Racing forums.

I plan on doing a RB20 swap, and if I can get the funds, then it will be a RB25 since they are similar, just a driveshaft and a few other things. Selling some of my old Supra parts to get enough funds. How much did everything run you so far?

You didn't change the headgasket? I plan on doing a timing service and a Tomei headgasket on my engine with a full engine gasket set. Don't worry about me, I am very very keen about these things. I just hate any kind of leaks.

s***, I spent about 600 dollars in silicone hoses, from coolant to vaccum, for my Supra, even steel braided clutch lines.

[Lonismos14]

^^ This sounds like one bad supra got any pics?

[IBoughtAS13]

I DO NOT MEAN TO THREAD JACK, BLAME HIM.^ LOL! JUST KIDDING.







Turbo cannot be rotated, well this one can't, it would touch the runners on the manifold.
The guy's favorite color was red I believe. The hood was just open, it is not actually like that. Hopefully I can finish off this Supra soon and start on the S13. You know, Toyota and Nissan....make the Honda kid cry.

More recent pictures hopefully tomorrow.

[smitty41393]

the rb sounds soooo good. nice work! did you have to do any drive train work to get the rb in there i know you have to with the rb25 but not sure bout the rb20..

Haha, its all good. I miss my MA70! I had the same car, non turbo and swapped in the same motor. 7m-GTE. Dont mind the wing, this was my first build ever. I was 17 lol and in high school when wings were all the hype

Notice i'm still rockin' the same wheels! Just different color! lol got my money's worth

the rb sounds soooo good. nice work! did you have to do any drive train work to get the rb in there i know you have to with the rb25 but not sure bout the rb20..

Driveshaft yea. Rb25 transmission is a bit longer so custom propeller is needed

[IBoughtAS13]

You Supra was a 91 or 92? It has the rare Sunroof. Your a douchebag for selling that. They are worth a lot now, extremely rare.

Propellor? You mean the yolk on the back of the gearbox? Did you do anything timing related to your RB20? Waterpump, pulleys and gaskets? How does the RB20 pull, if it is pretty good, then I will do that instead of a RB25 and bolt on a huge spoolable turbo.
