Ok please don`t flame or kill me for posting. I have searched and looked for similar builds but there all bit different.

Just looking if what all i have had done it will get to my power goal i have on my mind.

I pieced together used parts since I am on a budget.

I will list details below that i have had done:

Block:
B18c1 Darton Mid sleeves was 81mm now 82mm
Wiseco 8:8:1 pistons (used to have CP 9:1 but one cly broke a ring land that was the cause of smoke)
Eagle rods
ACL bearings
ARP rod, main, head studs

Head:
Portflow b16 head
BC stage 2 cams
BC springs and retainers
flat face valves
bronze valve guides
Victor X IM with S2 70mm TB

1000cc Precision injectors
Aeromotive FPR
Walbro 255
full 3" turbo back exhaust
Custom ram horn with dual 38mm waste gates
Large intercooler
turbonetics GTK 650 turbine
Crome chipped ecu with Ostrich 2.0

My weak point i know is the trans as it is a JDM ITR LSD trans

I maybe missing some small things but the main items are listed.

I am looking to get tuned on Pump 92 octane.

I know its lies in a good tuner but in everyone who replies opinion, will the current parts list and setup will it safely support 550whp+ on pump? OR am i overshooting my HP goals?

Any help or advice will be greatly appreciated.

thanks for the time in advance.

Please pardon my ignorance if this post annoys anyone, I am honestly just asking the budget items i was able to source will hit my WHP goals

LightningTeg

I would not go farther then 500whp at max on 93. I also dont understand the dual wastegates on a log manifold

You won't even get close to 500 on straight pump gas. More like 450 at most.

Also that size turbocharger at the pressures you plan on running won't even remotely need two wastegates, much less ones that big. I have that same revhardmanifold and the setup it came off of held boost levels just fine on a similarly sized turbo with a single 38mm wastegate.

You need e85 to make the power you want at least

2slicc

thank you very much for the input.

May I ask is there something besides fuel i need to change to get to my WHP goal or am I limited due to wanting to stick with 92 octane pump fuel.

reason behind me wanting to stick with pump is due to I live pretty far from any E85 source or tuner shops that have access to the better fuels.

2slicc

Is it bad? i got it for a good price the person before had it and put down 634Whp with paperwork to back it up, so i figured it would work for me.

LightningTeg

It will work, but you will be running higher boost pressures to make it happen.

When I switched from a log manifold like that to a ramhorn, along with E85 I picked up ~60whp.

methanol injection will help a bit... however you're chemically limited by the fuels ability to resist pre-ignition (detonation). really 450 is about the "safe" limit for a pump gas tune. anything above that and you'll notice the car will become extremely sensitive to fuel quality. Get one bad tank of fuel and you can kiss your motor goodbye

Is the turbo the limiting factor here, i'm unfamiliar with it?

wantboost

iTrader: (2)

and again, that isn't a custom manifold nor is it a ramhorn.

it's simply a tubular revhard shorty manifold. I have one.

2slicc

Is the mainfold any good then? Will it support my goals or should i start scouting for a new manifold?

wantboost

iTrader: (2)

It'll be fine. Granted a t4 turbine side is big for what you're trying to make.

wantboost

iTrader: (2)

You want to buy another one lol. I don't need mine anymore.

2slicc

I'm good I've got one. So you think someone went crazy and added another WG exit on the other side?

I really appreciate everyone's input.

Any more info is greatly appreciated. I am going to consider E85 tune. I am somewhat set at 550whp+ it's more a personal goal.

With my current setup if I was to go E85 then would my 550 # be obtainable?

I "think" my setup should hold up?

wantboost

iTrader: (2)

That's exactly what someone did. You'll need way bigger injectors and a bigger pump for that power on e85. You might get near 400 with 1000s but not all the way. Remember e85 takes around roughly 30%-40% more fuel to make the same power as e10 pump gas.

B20VtecVillain

X2 on that. Definately need quite a bit more per volume e85 vs gasoline. Another viable option that is kind of a mid way point is a fuel additive appropriately called "race fuel". Added to high grade pump you can effectively bring the octane rating well into the 100s and safely make quite a bit more power than standard pump alone, and it is a pretty inexpensive route. It's the mix i personally run in a near 13:1 street motor and it still loves a boatload of timing with no knock on that fuel.

Your limiting factor period is the exhaust manifold design.

Find yourself a manifold with some runner length to it, and a proper merge collector, and you will make more power, and make your tuner's life infinitely easier.

And when you make a tuner's life easier, your life is happier.

2slicc

^^^^ So it was a bad choice for me to get this manifold as i traded my SPA top mount and downpipe for the revhard and downpipe?

Or would I have been in the same boat with the SPA cast top mount ?

B20VtecVillain

Hate to say it but I do think you would have been better off with the top mount manifold. However I'm a bit confused because your post says you have a ram horn but the pic almost looks like a log manifold. Ideally a full ram horn design isn't terrible, but as was said before having a proper merge will allow for better spool and more efficient use of the exhaust gases being forced to the hot side of your turbo.

B20VtecVillain

I should note that I have only had experience with the SPA manifold on a D series not a B, but it was a decent manifold and I made good power with it and never had any issues with it cracking or deteriorating at all after a few years of daily street use.

People have made over 600 on a log manifold. It's not optimal but it gets the job done. The revhard uses large primaries and has a quasi collector do it's a step above a log, it's more like a mini mini ram.

D-Rob

And those same engines would make another 50-80whp on a long-runner tubular manifold, while being nicer to the engine by getting heat and exhaust pressure away from the cylinder head.

"Not optimal" isn't the term I would use for putting a runner-less manifold on a high-flow Honda engine. "Sin."

I have a spa manifold for my b16 for sale, sorry I'm new didn't know if maybe it would bolt up private message me if anyone is interested the guy I got it from said it maybe had 5000miles on it I'm going another route thanks

wantboost

iTrader: (2)

That is a very good point. Although it is better than a common log and your typical cast manifold. I just don't know why anyone would put a second gate on that manifold. They were designed to use the 40mm two bolt Turbosmart wastegates or whatever and with a properly sized turbo at typical pressure ratios had few issues controlling boost... Also remember this manifold was designed and built in the early to mid 2000s and even then with the technology of the day it got the job done.

OP how much are you looking for? trades?

Oh do you know if John is still working on NismoTronic for the VG30DETT still? IIRC the last time I talked to him he was thinking about it. Still want to try it on my sr20det for the sake of eliminating the MAF while still using the stock ecu before I go full standalone.


And I want trying to scare him with the fuel issue. There's a chemical limit to the fuels ability to resist detonation. Typically that safe point on a vtec Honda motor it's under 450. Any higher than that and one bad tank of fuel or one good knock and it's boom boom motor. E85 is the way to go if you want more power efficiently and safely.
