McRussellPants · 03-01-2008, 04:26 PM

looks kinda wack.

is that a T6 hotside?

gsracer · 03-01-2008, 04:30 PM

Its a holset h2c like a big t4. Unfourtantly i cant for the life of me get twins to fit. So as im stuck with a single i just want to see how wack it would look , unfourtanly its either this or a vortech. I think this has less wackness than a vortech thats for sure. As for this turbo its just for fitment purposes. Im havent really decided what turbo to run yet but probably something in the t4 twin scroll area.

240sx_sr20det · 03-01-2008, 04:44 PM

Wow that sounds good! +1

SicBastard · 03-01-2008, 05:12 PM

My understanding is that there is no gain to be had from a twin scroll with 8 cylinders, so keep it simple. And v8s with turbos are not capable of looking, "kinda whack." Bad ass I say. Keep it up!

Two questions:
What would you have to do for engine management with the turbo?
And were you dissapointed with the n/a power?

ECU rom tune
N/a power =

McRussellPants · 03-01-2008, 06:08 PM

Twin 30Rs up in the front tubs.

exhaust runs over the valve cover. (v-banded it wouldn't be too big of a bitch and wrapped of course)

headers run below the valve cover.

looks like you have room for it just glancing at it, someone did it in an S13.

Get someone to make you an intake manifold, that shit is not so fresh at all, and will if you had it going through the middle with the rad laid down a little (vetteish) would make it perfect for two intercoolers.

blueshark123 · 03-01-2008, 06:23 PM

just read the build man u got some skills i really like the idea of that turbo

Gjohnson7 · 03-01-2008, 06:37 PM

Man I don't care what anyone says, that's freaking Hottt!!!!

bardabe · 03-01-2008, 07:33 PM

The Holset H2C will be amazing and will spool fast, even a Holset HX35 will spool amazingly fast specally on that 4.5litre. The dude that bought my RB20 S13 has a Holset HX35 and is looking at 3000ish rpm full 18lb spool up. thats on a 2.0 i say keep the holset in mind. looks bad ass if you ask me, polish the intake side poweder / heatcoat the hot side red/black. it wud be so nice.

vaughn4 · 03-01-2008, 07:46 PM

new paint or just a silver kouki front end? do you have any new pictures of the exterior? not too sure about the turbo setup. i think i would rather have a supercharged v8. more of that instant torque feeling.

PoorMans180SX · 03-01-2008, 11:45 PM

Mmmmm OHC V8 turbo sounds are instant turn-ons.

McRussell had some good suggestions. I vote yes on the new intake mani, it would open up the powerband and give you more room to work with (throttle body location and such). Two twin-scrolls would be nice. Only with some crazy tube manifolds though.

Single would work though too. Easier. Just make sure you ceramic coat everything, that engine bay is packed.

Love the fact that you're keeping the VH.

projectdrifter · 03-01-2008, 11:50 PM

a nice rear mount turbo setup would be pimp. minimal lag v8 nastyness. love ur setup cant wait to see the new results

thats pretty optimistic.

*kingkilburn* · 03-02-2008, 02:06 AM

+1 for rear mount.

gsracer · 03-02-2008, 07:28 PM

After looking at all my options i may be going twins, with a rear mount radiator. Got to do some more test fitting though. Heres some pics of todays progress

Had to take the engine out to remove the headers. Took most of the day.

I never posted before but heres the whole exhaust system out of the car. I might be selling the headers though.

ms!3 · 03-02-2008, 07:57 PM

pullin the motor this week.

wth why?

i have to take my headers out...

lmao, damn that is a tight fit. I like your car tho man. nice build

SR20d2fourT · 03-02-2008, 07:59 PM

AWESOME WORK BROTHA!!

+1 mirrion.

I want a V8 now. lol.

M374llic4 · 03-02-2008, 08:17 PM

You might want to consider an STS turbo style install. They mount their turbos mid to rear of the car for fitment and cooling purposes.

The turbocharger can be mounted anywhere but is typically placed under the vehicle so running the exhaust to and from the turbocharger (depending on your design) is as simple as replacing a muffler and can be done by any competent exhaust shop. Once the turbo has been installed in the exhaust system, the intake tubing can be fabricated to run from the compressor outlet up to the throttle body. In most cases, the intake tubing acts as a linear intercooler and will provide 40-50% intercooer efficiency with almost zero pressure drop if designed properly. If you are looking for optimal horsepower per pound of boost, adding a front mounted intercooler to your remote mounted turbo system will provide 90% to nearly100% intercooling efficiency.

JM216S14 · 03-02-2008, 08:21 PM

This is one of the coolest engine swaps Ive seen! VH45DE freaking sweeeeeetttt

DarkPhoenix · 03-03-2008, 01:28 AM

Very nice. I can't wait to see what it will be like with the turbo in place.

Fargin' sweetness!!

racepar1 · 03-03-2008, 02:00 AM

Extremely nice swap! I don't agree with boosting it though. No turbocharged or supercharged engine can match the power delivery and ultra flat torque curve of a well-built v-8. With ITB's the top end would be bitchin as well. How does this motor compare in size/weight to an LSx? Anybody know? And what about the VQ35 as well?

UfoZ8myCow · 03-03-2008, 03:09 AM

There is nothing "kinda whack" about an S14 with a Nissan V8 and a turbo under the hood. Good luck with the rest of the build man!

this is based off of information from a friend of mine who has a turbo z28 Camaro
running 11 pounds of boost and putting close to 400ish hp

SicBastard · 03-03-2008, 08:14 AM

Rear mounts are bullshit.Your turbos become completely dependent upon some weak ass electric oil pump and the amount of heat energy wasted in the exhaust is rediculous. You keep seeing them on v8s and v6s because with their inherent torque people just don't realize/accept all of the midrange that they are giving up.You've already built a great exhaust, you should really reconsider a centrifugal. Don't rull out a supercharger just because zilvians think turbos are cooler.Also the way that the stock lower intake manifolds creates a flat plane is just begging for you to fab-up an upper plenum/air2water ic/mount for a cobra eaton. $600 and you're looking at 500 hp and your radiator worries would be gone because the air2water ic requires only a small heat exchanger out front.Keep moddin Bro! It all looks great!

This holds for a lot of other things as well. Do what your wallet and brain dictates. Don't listen to people who have neither and haven't done anything.

gsracer · 03-03-2008, 09:03 AM

I think I have figured out a pretty efficient way to get twins to fit here. I actually got two ideas I'm working on. It should look pretty baller and work well either way. I'm also thinking about doing a rear mount radiator ala dentsport to get some weight back over the rear.

As for rear turbo I never really liked the idea of rear turbo seems like its less than optimal.

And I definitly won't be going with any of the gt class turbos. I'll probably get twin t3/t4 or t3/60-1. I have instant torque as it is so its really a non issue IMO.

IIIXziuR · 03-03-2008, 09:21 AM

Either way its sliced, I think this built is cool.
Keep up the good work man!

I think once everything is finalized and buttoned up it will be sick

Sir · 03-03-2008, 09:30 AM

man, my favorite build is getting better and better.
I was worried when i saw it for sale, but now I'm happy again

Keep up the good work.

I'm trying to talk my buddy to do this in this S13...

gsracer · 03-03-2008, 05:38 PM

Picked up a garret t3/60-1 from a friend and got my merge collectors to try to come up with ideas. The down pipe can only go over the valve covers and down the back, but manifold wise i got few options.

I could run a baller stainless tublar manifold and make it look all types of bad ass but as you coul see i would have all kinds of fitment issues. .. pic

obviously id chop off the bulk of the collector and weld on a t3 flange

or i could make a simple and easy log manifold and sit the turbos like so but not as bad ass

I though about bottom mount two t28's but you can see the room im working with
