ae86. vvti 1uzfe. hmmmmm

[bmx269]

It has been a long damn time since I have posted here, so here goes. After killing my last built sr20 at Seattle FD 2011, I said I was done with sr20's. The last one was caused by a broken fuel pump. Stupid causes are always the most painful.

So I bought this:

A 1998 GS400 VVTI 1uzfe.
Put a w58, Aluminum flywheel, ACT 6 puck clutch, custom exhaust, Haltech Platinum Sport 1000, and way too much time into this car.

I had a baby girl come into my life last Sept, so the build process was slow. But no big deal, I kept on trucking.

Here are some of the pics of the build:

exhaust


wiring started, also a shot of the modified cruise control to bypass drive by wire


and then a video of how is sounds. The car has not been on the dyno for tuning yet, so the numbers and drivability are still unknown, but it feels torque happy. The subframe was not dropped, the tranny tunnel was just pounded a bit more then for the SR. Fun.

Since that video, we did some street tuning, and man this car is stupid fast now. Next season will be a blast.

Sorry, do not know why my pics are not loading inline.

Edit, it was the settings in the UserCP. Inline images were turned off. Weird

Fantastic!

What ECU did you use?

 

[bmx269]

Haltech Platinum Sport 1000

 

[Lextreme II]

Wow.. impressive....

 

[bmx269]

I will take some more complete pictures soon. Thanks

Very nice. are you using stock engine management or something else that can handle the vvti?

Said he used http://www.haltech.com/product/platinum-sport-series/the-platinum-sport-1000/

Yes a good tuner can make it work..

Updated picture.

niceeeeeeeeeeeeeeee

 

[slipway]

awesome keen to see some numbers. will sound so good at wot.

 

[Da Coupe]

Nice to see you went with the vvti! Care to share how you modified the TB to eliminate drive by wire?

Love the conversion, I've got a vvti and manual trans in an e30 BMW, great all round package, and awesome noise at full throttle!!!!

Well, after all that stupid drama, that I got all bent out of shape for, we got some time and got the Haltech tuned. Took it to a Dyno Dynamics dyno in Richmond.



291hp and 300ftlbs of torque, in a 2200lb car is going to be great. The dip was smoothed out after this pic was taken, with some of the vvti timing adjustment. Overall the 4 litre engine performed excellently.

and for comparison, here is my team mate Ian's R32 Skyline with VK56 on the same dyno when it was NA. Pretty close power considering the engine is 15 years older tech and 1.6L less displacement.


My car and Ian's are both using the Haltech Platinum Sport 1000. I have my redline set to 7500rpm

I also hit the track yesterday.

That is a great result! Sounds awesome. I never get sick of the noise of these engines!!! Any plans for 1/4 mile run?

 

[bmx269]

I may just for shits and giggles. Right now I am working on cooling, and a coolant expansion tank / swirlpot setup.

How did you get the VVTI working? Or is it not? Cool project!

 

[bmx269]

it is triggered by the ecu, and yes it is working.

 

[bmx269]

Ok, No that I have some time to write, here are some more details.

to get the VVTI 1uzfe running, and setup, it was all Bill at The Independent Speed Shop (http://indy-speed.com) and his crazy mastermind skills that got the system sorted out. For him it was not too difficult, but that is due to his years of experience. He custom created the map, as there is no base map for that engine for the Haltech ecu.

The Independent Speed Shop did a lot of custom work for me, including the exhaust from manifold back, the w58 adapter plate, and even help with other fab work, as I am not a mechanic or fabricator. Without Bill and Indy Speed's help I would have probably spent more and got less for this car.

If you want to talk to Bill about the VVTI setup or what was involved, I am sure I can get him to answer some questions for you.

Overall this engine is awesome for this car, is it the best for other cars? I can not answer that. I just regret not going v8 earlier.

Looking at your graph is interesting. I tuned a setup in an RX7 the other day similar ideas for the overall setup running a Link Xtreme. I'm always a bit reluctant to compare dyno figures from different dynos but our results are very similar except our torque curves are mirror image at 4K. I have less below and more above where you have more down low and les up top. The engine I did has had the intake runners removed which I didnt think was a good idea. Now Im wondering if that is the difference. I want to get back onto the dyno with the car now.
