Should My Hks Gt-Rs Be Making Boost Earlier? (E85)

[LaurelPWR]

I used ARP flywheel bolts on my RB25 and they were fine. The packet they came in said they were for a 3S-GTE (toyota 4 cylinder) but they worked perfectly for me. Exactly what bolts were you using? A rebuild is better than losing your feet.

and yeah dude im super thankful nothing actually came off completely while driving/dynoing.....could have been devastating!

[LaurelPWR]

So I'm at this stage now all over again.... Turns out the bottom end had been previously over honed and should have had forgies installed the last rebuild.....

[LaurelPWR]

Also I might add.... Anyone planning to use ARP RB flywheel bolt set make sure you measure and check them against your factory bolts before installing .....

As a target for you to aim for, my GT-RS makes 5psi at 2000rpm. However, I have a very trick exhaust manifold and run an external gate with the internal wastegate welded shut.

I also have tomei poncams in my RB25, though still run the standard lower runners with a plenum top similar in principle to a plazmaman.

I also have this custom bad boy I scored going on so should also help a tad with better spool ....

[Blackkers]

Is that the hybrid low mount manifold? Where'd you pick that up?

Looks like an eBay stainless one.

I personally wouldn't use it. Stock is fine and won't crack.

It's definitely not an eBay manifold I've seen a few of them (they are puss) and the quality of this one is that of a professional. Not to mention I can't find any other manifolds bar one in japan that have the runner configuration of this particular one.... (three at back of motor)

[LaurelPWR]

I don't know if it's hybrid or what is is really but I guy had it for sale for 150 do I bought it just to have a look at it honestly .... But after seeing the quality I have decided to use it lol

[LaurelPWR]

Finally after a mountain of random happenings, my s13 goes back onto the dyno (again) today .... Wish me luck haha

make sure you strengthen/gusset it where you can...especially if your exhaust system isn't supported properly....a lot of weight hangs off it.... and they crack and warp.

So finally got my car back....

Blue line is the old E85 tune...

[LaurelPWR]

Anyone else getting this result on a similar set up?

[Hadouken]

Looks good from my house

Cheers bruh!! Haha I was pretty freakin stoked with the end result considering all the dramas I had then when it was all finally done no one said "nice effort" or anything at all lol sad panda

I personally haven't seen anyone else achieve this with a HKS gtrs so I thought someone woulda had some praise lol

[Hadouken]

I know of a few sr20's that are set up close to this. They are fun haha
