Stock springs are NO issue with the HKS (and many other) mild cams.
I don’t have time to read the whole thing now (sorry), but just do 2 255’s in the tank and be done with it. Personally, I run an activation light when the 2nd pump gets voltage, and I also look for the change in fuel pressure. I ‘operational check’ it each time i drive the car.
FWIW, this thing would be an ANIMAL with an HTA86, INSANE powerband! Can’t wait to check it out.
if you want a one stop shop for supra/2jz knowledge, give rich at majestic motorsports in jacksonville, nc a call… ive seen a TON of his work around and NEVER heard a bad thing about him, or his shop… when it comes to 2jz, he’s probably one of the most knowledgable people in the game… he’s taking his white supra to tx2k12 with 1400+ spinning on the dyno and hunting for UGR lambos…
Yeah, I was making the power he’s looking for 12 years ago, it’s a simple, proven formula with these engines.
i was just offering up some help and another point of reference… anyway
I guess, whatever. Honestly making 750HP on a 2JZ these days is as easy as it was to make 300HP from a SBC in 1975.
the car has a home made duel 255 hanger in it now, i guess ill tear it out and see how well ins made and go from there for pumps.
Replace/mod the pumps, -6 feed, and be done!
I run the twin 044’s without issue.
Some dudes run the big Weldon, but I read a lot of mixed reviews. (Adam knows his shit though, so no hate here).
I make 750-800whp on E85.
Buy a TRD diff if you can afford it.
Stock intake mani is fine for that, just ugly.
what injectors are you running ryan?
Precision 1600’s.
They are OK, were there when I got the car. I’d probably do ID1000/2000 if I could do it over.
what do you guys think about the id 1000’s. think upped base pressure would support 750whp on E85?
No… I think you would need bigger ones.
Just go FIC 2150’s man, you know you’ll eventually want more power! ID2000s are fine too, just more expensive.
The twin 255’s modded will support 1000WHP on E85 with a -6 feed line.
the car has 2-255’s in it now, i just need to rip it out and see how he did the hanger, how do you mod them? any links?
weldon is big bucks. but everyone starts with a dual, goes triple, then just buy s a weldon 2345 anyway
Pretty sure lconrad went to 2 044’s.
He went from double, to triple to 2 044’s I think. But I can’t remember.
Oh, and on my old car I ran 2 Denso pumps, no issues with them. Performed great and didn’t sound like I had a supercharger whining the entire time. The noise has grown on me though and I enjoy it now. :rofl
You can put a TRD diff in a RX-7?
