Engine is going in tonight....

Fresh built stock short block
1.3mm HG
RAS
stock cams(for now)
real MHI t2 20G
JGY rail with 75lb delphi inj
nismo FPR
Nistune on E85
Deatschwerks 300 pump hardwired
6 puck sprung hub ceramic clutch
4.36 skyline vlsd
z32 30mm alum front brakes
full suspension arm kit
CS poly mounts
etc, etc.....

We hope to tune it on a 4bar E85 setup with the current fuel system. 18psi on the street and 24psi on kill.

I'm curious where the 8cm2 T2 20G will choke. It should be a tq monster on E85 with stock cams and intake. I would like some JWT S4's or some GSC S1's down the line....

She is in... We hope to break it in on the gate and dyno tune 6/4 on corn.....

was the e85 just a simple tune? or did u have to change the fuel lines and fuel pump also?

The fuel system was designed for E85 from the beginning. DW300 supports 600whp on E85 and my 75lb injectors will be the bottle neck at about 420whp at 90% duty cycle at 4 bar base pressure. You either want a full stand alone or nistune if your going 4bar base fuel pressure because JWT and enthalpy tune at 3bar.

E85 takes 30% more fuel than gas. Changing from 3bar to 4bar base pressure increases fuel flow roughly 30%.

75lb injectors=780cc

780cc injectors at 3bar base pressure= 900cc at 4bar base pressure

Don't attempt this without proper tuning!

We are getting closer but I think it will be mid june before the fresh engine is broken in and we see the dyno.....

Can't wait to see how the 20g stacks up against other T2 setups on here. With some good cams and nistune on E85 I think she could be nasty!!!

what manifold do you have? is the setup very stockish in terms of fitment?(bottom mount, elbow/downpipe fit well) thanks. i'm thinking of getting a 20g as well for my sr...good luck on your awesome build.

It fits like stock, you could use the oem mani and elbow if you chose to. It is set up just like a GT28. So you need a GT style oil drain flange and the GT style compressor in/out adaptors to clock your oem suction pipe and compressor outlet and your done.....

She is running, AC and all..... We put a base map in it but it only ran on two cylinders because we had two injector resistors that were the wrong ohm rating. Fixed that and its running well but the tune is super lean. We will iron that out this week and I plan to dyno tune in a couple of weeks.

Awesome build! can you post a vid of the dyno run? Is an e85 conversion really that easy? Good luck! Also, post some dyno figures or results.

We have the tune running good off boost and drivablility on E85. The nismo FPR was over torqued and broke .....

Installing a block off plate and aeromotive FPR tomorrow to try and get it to hold some fuel pressure and not lean out under boost.

Its running on the gate at 18psi on E85. 12° timing and a fat tune at 10.3-10.5 at WOT. It is very impressive so far. Here is a video...

Street tuned it for about 20min and took it strait to the local 1/8th mile for some shake down passes... Got the afr's in the 11.2 range and timing is at 18° at WOT. The motor has about 400 miles on it and it's still running on the gate at 18psi. The rev limiter is set at 7200rpm and I short shifted at 6800rpm all night. Here is a video of the first pass ever..... It went [email protected] and went 7.64@91 on the 5th and final pass of the night. She's gonna be sick with cams, a quality CAC, and 25psi

Well it's got about 700-800 miles on it and 3 oil changes. We've been to the track in cville TN twice now. With the best pass of 7.61@93 in the absolute worst conditions. About 90°+ and stupid humidity. This is on the waste gate with it touching 21psi and dropping pretty quick to 18psi. This is street tuned on E85 with nistune. Needless to say I'm thrilled!

I'm going to dyno tune it in September and then add cams and a boost controller. I'd like to see about 24-25psi and settle to 21+. Then it's going to beech bend in BG KY in October. This car won't go 10's without some head work and some forged internals but it should go 11.5 or better on a clean pass.

Big thanks to Glenn Hecker(co-owner), Rory(Nistuner), and the pit crew from garland nissan in Hopkinsville KY!

I know this isn't saying much, but I'm not aware of another sr20 240sx in the country going faster than this with a stock style T2 turbo. This car is a true daily driver with AC, PS, 7" touch screen, sunroof, and all power options. I'm sure there might be one out there with a GT3071r in a T2 housing going 10's but I haven't seen it.

I will be adding some HKS cams and dyno tuning very soon. She has already shocked me with stock cams, head, and long runner intake. She did this at 24psi falling to 21 thru the traps. It bounced off the limiter at 7600rpm's in 3rd with about 50-75 feet left in the 1/8th. I'm taking the 4.36 diff out and switching to a Z32 4.08 vlsd tomorrow. Should be good for 8-10 more mph in 3rd.....



It's geared to run 95mph in 3rd with a 26" tire and I never thought I'd run out of gear

It's never even been on a dyno. Just street tuned on nistune.

Yes, that's a 1.57 60' in a stock T2 turbo'd SR20 240:)

Has anyone ever been that quick or fast in a T2 turboed car??

If you dont mind my asking where did you pick up that turbo? I am along time Dsm guy (now a 240 guy ) and I have never seen a Mhi t2 20g. All of the ones I have seen off Fuso's are like 10cm2 t3 back sides, that people convert to 7 or 8cm2 for 4g63 uses. I would be very interested in getting of my self!

At one time Forced Performance made them. I don't think they still do but you never know what a phone call could do dan.

FP never made them. They purchased them from Kamaka performance out of Tiahland. The same manufacturer that makes them for ZTL motorsports out of Canada. Which is where I bought mine from via koukimonsters link.....

This is my favorite turbo on the SR but it could be becuase all myother turbos were on 93 and a JWT rom tun with 15° of timing and this one is on nistune and E85.

I've had a GT2871R, GT30R, holset HX35, and this turbo is the s***. But the E85 and 20° timing would have made the others shine too....

Looks like I gave FP too much credit lol good to know.

This is my turbo.... It rivals any T2 turbo I've ever been in and I had a GT2871R in 2006.

Hmmm...wonder what E85 is going to do now that Congress has stopped the subsidies for it's creation.

Looks like you will have some competition kentucky!!!! This summer I will be shooting for a clean low 10 pass and I have excactly that..... T2 gt3071r with loooottts of internals. Ill post my results come june. And what do you mean has stopped e-85 production? You have a link?

The subsidies were to fund the build of the plants that produce the E85. We have one here in Hopkinsville ky. Now that the plants are built the production will not stop. The price will always be slightly cheaper than pump gas.

I know a guy that has been 10's ion the 1/4 with a GT2871r but I'm not sure that the 3071 will make much more power in a t2 frame. The T2 turbine housing in obviously the bottle neck. We shall see. Anyone that wants to post timeslips and setups in here feel free....

I can definately vouch for the bottle neck issue. I'm going external wg to try and address this issue, which should be fun considering my mani is stainless steal vs a stock cast steal. Lol. Gotta find a really good tig welder.

"The subsidy has provided the oil and agribusiness industries with 45 cents per gallon of ethanol blended into gasoline." So it's more than just to build plants and I would assume there will be a "at the pump" cost increase per gallon unless the industry is simply going to eat it in less profit.

Anyway, sorry about the thread jack. Keep on with the build

I need a standalone. I'm kind of curious who will put down better times between you and I once I get one.

I have almost the exact same setup as you pyro. I'm running the emu to tune and have 26x11.5x16 mt et streets. External wastegate is going on next week and I as well, will be switching back to 4.08 gears and am saving for my vg trans kit. Other then that, the only thing you have significantly different is bigger injectors. Lets see who comes out with the fastest slips!

What cams? If you're still doing your motor work, I highly recommend you do solid lifters. With my S4 Cams and the 3071, you can feel the change in power from 4.3-5k (21 psi comes at 4.2-4.3) and it just keeps growing from there and wants to go well past my redline of 7.5... Solid lifters are definitely in my SR's future for this very reason.

Definately solid lifters! Lol I'm running the tomei 260 pro cams with tomei srings. I tell all my friends to run solids but not everyone I know is as passionate as me around here. s*** adds up. I totally feal ya on the wanting to go past redline. Makes me wish I would have went bigger turbo and higher red line (anything more than 26 psi on the gt3071 at 7600 rpm is off the compressor map)
