Long Story short ,BHG 7M-GTE - $7000+ in unsuccessful 7M build ,beign able to recover some of it and don’t really want to talk about it…

1JZ times ,good times

1JZ-GTE engine sources from Jarco ,took 2 just in case

The JZA-70 Engine looked great from outside:

But inside it was a mess:

Luckily the Front Sump engine was much better inside so I swaped the pans ,and was good to go.

As of todayZ date ,the car is running great. Rough mapping with the Safc was compleated ,but I do not feel quite ready to run it at 1barr (TiAL default sring) thus I'll wait to get a 0.6barr Spring from ATP tomorrow

Idle was set at 1000 to 1100.

IDL signal to be adjusted (found that IDL wire was somehow grounded in the harness ,what a pain to debug...)

Congrats dude.

So, did you relocate the battery due to necessity for the IC piping, or just ran the piping there because you had moved the battery?

 

[Justin727]

sweet!!!

I reloced the battery 2 years ago ,after my very first AutoX disappointment using summit Battery Reloc kit ,and later upgraded to Odyssey PC 925.

I kind of doubt that 2.5" cold Site piping is possible without Battery Relocation ,especially when the BOV is right before the Trottle Body...

 

[tlo86]

wow look at that oil!

and not only is 2.5'' possible, but 3'' is possible with a bov

what fans are you going to use with that rad?

Lol 3"+BOV

SPAL Dual 11" Fans on a PWR Radiator.

The Clearance to the Water Pump pulley studs is wayy to liitle righ now - <1 inch... I have to trim the SPAL shroud a bit more although with the 98TT motor mounts and new Toyota tranny mount the engine play is almost non existent ,possibly because the tyranny mount is super stretched towards the engine - guess the JZA70 bell housing was a little to short or something...

You're just not trying hard enough

I got 3", and the BOV in there, with stock fan

i notice the tranny mount too on mine.. i use solids and the clutch fan but i am kind of afraid to go PWR again id hate for the fan to be too close and dont wana fork over the $$ to find out lol

The tranny mount is really weird ,it has to be the "new" bell housing - because the engine seats perfectly. I even tried with the original JZA 70 Motor Mounts just to be sure that I was doing noThing wrong...

The tranny's mount center bolt is super stretched and the 4 bolts holding the bracket to the tranny-tunel are maxed out toward the engine ,there is good 1 to 1.5inch of lost noise space due to that - PWR even with "ultra" low profie SPAL electric fans will be a tight fit. I will grind the shroud as much as possible ,cut and rethread the water pump studs and report the clearance as soon as I measure it.

take a pic or i can so we can compare lol it sounds similar to how mine sits

Nice car. Lets keep the progress coming!:icon_bigg

Here is what it looks like on mine:

The engine seats properly ,but it is easy to tell even by just looking at the tail of the tranny to the driveshaft - tranny is nearly 1 inch further forward than what it is suppose to be. I would guess that since I've used new bell housing from Toyota ,it must've been defective (a little too short).
