I've been battling this issue recently with my mk3. 1jz 1989 with a R154. It started to refuse to crank over randomly when the engine is warm/hot. At first it was rare but now it's almost everytime the engine is hot. I redid the wiring harness last year, so i'm pretty confident the starter is...

1jz-gte from a jza70 in a ma70 1989. I was running a ms3pro, 800 sard injectors, stock ignition components including the igniter. I decided to make a new engine harness, swap the injectors for mk4 550cc(plus a resistor pack) and now I have a very very weak and orange spark. I can start the...

I altered my base map a bit I'm running 91octane on my 1jzgte Main mods: Driftmotion 6262 turbo kit Sard800 injectors stock cams 320lph aem fuel pump and here is my spark map: I'm running 18psi highboost and 15psi low boost. Boost cut is properly engaging @ 20psi and rev limiter...

1989 canadian mk3 turbo mt with a 1jz. I used DM 1jz/2jz mk3 mount bracket for the swap, however the engine wouldn't go in until I gave the firewall a bit of a beating near the area where the A/C evaporator rest agains't. It barely got in and the rear turbo intake pipe was always touching the...

here is my problem. Without boost controller it will spool to 11psi and stay there. With a turbosmart tee manual boost controller with added boost, it will spike to 14~16 psi then drop back to 11 psi by the time I get to 5500rpm (and all the way to 7500). Then I removed the "gate system" from...

I have a Soarer R154 with the supra extension housing, everything was perfect but then I rebuilt it and the output shaft oil seal leaks. I changed it twice now with brand new toyota seals, the fullface side facing the rear of the car and yet it keep leaking quite badly. The driveshaft is the...

basic mod: jza70 engine and ecu 3" stainless y-pipe with 3" downpipe and 3" muffler (stock cat on the line). 2.5" intercooler piping with 3" big driftmotion intercooler. safc II that's about the end of relevant mods. I hooked up my boost controller and put it on the lowest setting. Now...

Hello I recently swapped a 1jz-gte from a jza70 into my 89 turbo. I have two or three remaining issues. First is that my fpr is leaking where it bolt into the steel block (with the fuel feed hose). I tried changing the crush-washers but it still leaked a bit. How can I fix it permanently...

Opened my R154 trans today with a toyota mech I know weird thing: 1- All gears are BRAND FUCKING NEW (it's a 260 000Km virgin R154, never been rebuilt) 2- All syncro are in extremly good conditions 3- Almost all bearings were perfect, we had to hammer a few to open the trans, I'll change...

I'm trying to reinstall the wiring harness in my car but I can't make it go through the hole in the firewall. the connectors just seem to go with weird angle and get stuck behind the god damn blowfan. Is there any magic trick or something, it is the first time I'm reinstalling a harness in...

According to the 7mgte vacuum piping: http://www.cygnusx1.net/Supra/Library/EPC/291220/catalog.aspx?F=1708&P=6 the power steering seem to have two vacuum sources, the first being the accordeon hose, the second being the intake manifold. Why does it need the intake manifold, couldn't those...

This hose: 12263 is 36$ at toyota dealer. but at that price, Is there any sort of aftermarket an-10 hose or something a bit prettier that I could get. I'm trying to put some bling into the engine bay I need to replace it because it is leaking quite badly. also on the PCV system, the...

I have a 89' turbo MT. I changed my IC this week and noticed a "DENSO TOYOTA" sensor in front of the oil cooler, fixed with a semi-ridgid bracket, is that a temperature (external) sensor, what is it? I couldn,t find it in the TSRM. ---------- Post added at 07:58 PM ---------- Previous post...

it's a 7mgte with 550cc and lex maf. Everything is good until the car get warmed up to operating temps, then for like a minute or two, when I hold a constant speed, the car will let off the throttle and snap on it, kind of like fuel cut (but it isn't) and MUCH MUCH MUCH MUCH less aggressive and...

my r154 make this sound: http://www.youtube.com/watch?v=_LtHs0Zydew when the transmission spin if I put it in neutral and I press the clutch, it stop, but as soon as the inputshaft spin, it make this noise (but much worse). I was coming back from work, everything was fine then it started...

7mgte r154 approx 300rwhp right now, planning on 350rwhp~370rwhp at most stock clutch is starting to slip a bit when boosting 15 psi. It has done many many miles and is due to a change will a stock oem disc be able to witstand that much power? because I don't have the need for a super duper...

I don't know if this is normal. I had a stock-ct26 with a shimmed wastegate (around 9psi of boost). the turbo was DONE. I bought a ct-26 with a 57 trim and it was almost brand new (was used once on a drift car, he made over 400whp with it). I tried it and there is no power, my old ct-26 made...

This is not a joke, my hose blew while on a roadtrip and somebody took that picture, now that this has been fixed. I circled in red a hose coming from the back of the head, to a black module of some kind, with another coolant hose going from that module, into the firewall. I'm guessing this...

upper radiator hose blew on me, hopefully I was 2 street away from my destination (it didn't overheat). fixed it, filled it with coolant, couldn't burp properly where I was (drove it home, ~5 min drive). in that 5 min drive, the BOV (bosch generic) was not making the usual "WOOOSH" (releasing...
