And then word is he threw a bearing.

damn...

[Pocus]

any word on if it was one of the new borg warners that he was using with the extended tip tech.

Yes, it's the Borg Warner listed in this thread...the S374.

Quoted for iteration.

sick car i love it!!!!!!!! and revvin that bitch to 9500 rpms sounds familiar lol my teggy goes to 9500 rpms as well and i got a garret gt35 70trim bb turbo but i am only runnin 12 pounds of boost....but damn i cant wait to see some more pics and better yet vids of this crazy ass build ur workin on

[RB260SX]

I'm back guys, with a brand new motor, brand new build....I stuck with the Same engine components (of course new) as before, but with a Borg Warner S372 with 10" Race Cover and .90 A/R. This should help greatly with spool over the prior S374 with 9" cover and 1.10 A/R. Just the 10" Race Cover is good for another 60whp over the 9", which is dyno proven.

Turbo is good for 850whp, and I should have some dyno numbers to post in the next 2-3 weeks.

I'll post up new pics soon...

[Pocus]

Wow I was woundering what had happened to this project. Can't wait to see the new pics and hear the new numbers

[Dave]

schwing!!

[RB260SX]

I want to start out by thanking the guys at Abel Racing in Midwest City, OK (Specifically Erwin, who goes by Efeezi on the various online forums.) You guys have been a pleasure to work with, and your knowledge of all things Nissan is amazing.

It's been six months since the 240SX encountered bearing damage, which led to a full motor rebuild.

This downtime gave me the opportunity to rethink the current engine configuration, etc. While I was happy with the power of the Borg Warner 74mm (1.10 A/R) turbo with 9" cover, the spool characteristics weren't ideal for a street car IMO, and I wanted something that could make similar power, while providing a larger powerband.

After consulting Borg Warner, they recommended their 72mm (.90 A/R) ETT Turbo with their new 10" Race Cover, which has been dyno proven to make up to 60whp over their standard 9" cover.

The motor was rebuilt with an N1 Crank, JE Pistons, and Eagle Rods. Head was left untouched from the previous setup, complete with Tomei Hardware and 260/260 Poncams.

The car now sports the new Tial 50mm Q BOV, which sounds amazing, to go along with the Tial 60mm wastegate, and I'll have some dyno videos to post this weekend, pending all goes as planned.

Here's some sneak peaks from what's to come. Forgive the dust, it's been tucked away in the corner of the shop for several months awaiting parts.

[kevind]

thats a big turbo :eek:

so where does it spool at? its got to be above 7000rpm....

[RB260SX]

4500 RPM full boost

[Boosted98gsx]

maybe with the boost controller set to 2 psi lol

[importpunch]

HOLY SHIT. Take video when someone calls you out.

[06black6spd]

so how much does a build like this cost?

[kevind]

whats the displacement on the motor now? 2.6L?

i would like to see a plot of the car on the STREET (not loaded on the dyno), in 3rd gear, and see the graph of the spool....

[Pocus]

Just because it's a big turbo doesn't mean it's not possible for the turbo to spool up as quickly as he is saying. allot of things come into play when your talking spool characteristics. Things such as displacement, manifold design, the specifics of the turbo itself, and the cams all play major rolls in how the turbo spools. This is also the difference between a cheep off the shelf turbo such as a garrett and a borg warner with their new turbo line. I was looking into going with a borg warner but desided to go through a different company for a custom made triple ball bearing turbo built for my setup.

Really looking forward to seeing what your new setup puts down. i love this build and wish i had the money to do something along the same lines.

[RB260SX]

The car was completed today, and I’m very pleased with the finished product. The plan is to dyno tune the car tomorrow, and I’ll upload the graphs as soon as we finish. The car sounds beastly in person, I wish you all could see it in person.

Special thanks again to corporate sponsors: BF Goodrich Tires, Tial Motorsports, Borg Warner, Abel Racing, Je Pistons, Eagle Rods, Tomei USA, and many others along the way for your help with the vehicle.

As promised, here is the debut video of the new setup:

[Pocus]

the car sounds insane. Are you going to have video of it on the dyno as well?

Looking forward to seeing the numbers

[RB260SX]

Yes, I'll have dyno video. I have nothing to hide..

[Dave]

im thinking wider rear fenders and wheels would be siick

[RB260SX]

Switched out the Walbro's for dual Denso Supra Pumps....

Result is 810whp/560tq @28 PSI....More Power to come, needs a larger exhaust housing on the turbo and more boost!

[Pocus]

so what are you using for tuning on this?

[RB260SX]

AEM EMS with 5-Bar Map Sensor, E85 Fuel....

[Pocus]

Nice. Just so happens thats what I just switched to. Only using a 3.5bar sensor for now however. But yeah E85 is the way to go.

[Dave]

:eek:

[jdmtyperaccord]

sick sick sick, ive always wanted a 240 like yours with an rb

[SickC5]

I was curious to know what the build cost was as well...

[1sikgts]

that cars dirty im jealous lol that thing must be so loud especially with an exhaust like that. what size are your rear tires

[sneakyae86]

[blackdude]

[redrum90]

what is a turbo back exhaust

Basically exactly what it sounds like. Its new exhaust all the way from the turbo to where ever the exhaust exits the car. It generally replaces the catalytic converter and any other restrictions with straight pipe.

[redrum90]

Ok thanks for the info
