SM105K's SHO BIBLE/BUILDS/LIFE

[802SHO]

Glad to see you haven’t completely turned your back on the old girl! Impressive gains from that HPFP!

 

[luigisho]

Honestly, I wish I would have done the fuel pump second after the tune. Those are biggest power gainers. However the HPFP isn't the cheapest so....yeah.

That is good info for future and current owners looking for that power bump and deciding where to focus.

I tell anyone that will listen, and even some that won't, the first thing after the tune... do the HPFP before the other big ticket items and you will net your biggest gains with e30. Because of all the great info on this page, that's what I did, and barely noticed the other stuff after the HPFP.

I don't own this generation of cars and skim this section and pick up info on the fly. This is encouraging to have more than one person (if there are others they should consolidate in this or another thread for new people looking in the future) state this in one place. Just looking through, I thought this was an addition toward the end to squeeze the last amount of power out of the platform. It is good to be wrong, and even better to make sure this gets disseminated as common general knowledge. Excellent.

I agree 100%. I will give a quick run down of how each mod upped the power.

So from my research most stock SHO's put about 290 HP and 300 TQ on average.

Full disclaimer: Brad from AJP Turbo is the only person who has tuned my car.

When I first tuned the car (plugs, K&N drop in) on 91 octane it made 366 HP and 414 TQ in 105 degree heat. so +76 HP and +114 TQ over stock.

Next was the E30 tune. Car made 391 HP and 470 TQ on 91 octane with Torco T85 E30 mix in 90 degree heat with the stock HPFP. E30 added +25 HP and 56 HP for a +101 HP and +170 TQ over stock.

Literally just the AJP Turbo E30 tune was the biggest bang for the buck in my build.

Then came the GH IC. The car actually lost power in cooler temps with a revision. The GH IC was a bit too big for my particular turbos. Car made 388 HP and 463 TQ on two less PSI of boost. So -3 HP and -7 TQ made +98 HP and +163 TQ over stock. Brad did state in an email this could happen, because he was seeing boost tapering bad on my car in the logs.

Next my full exhaust mod. Revised AJPTurbo E30 tune on stock HPFP, Gearhead Intercooler, PPE Catted Downpipes, Custom Magnaflow Resonator. DP's and Custom Magnaflow Resonator, going through stock mufflers netted me +3 HP and +24 TQ bringing up the numbers to +101 HP and +194 TQ over stock.

Finished the cycle with the FS HPFP (who I bought from BPD) and removed the GH IC and replaced with a stock unit. I documented it in detail earlier in this thread. Brad sent me a revision for the HPFP and stock IC. Car was on 91 mixed with pump E54 for pump E30. Car actually made 414 HP on the first pull but TQ didn't register because of the connection to the MSD coils. He fixed the issue and the second pull netted 411 HP and 546 TQ. However if you look at the dyno sheet, he didn't actually get the true peak. It is probably in the 555 to 565 TQ range because it was already falling before the dyno recorded. So +20 HP and +52 TQ finishing the numbers at +121 HP and +246 TQ over stock.

If you had to do it over with the Taurus, would you change anything?

After thinking about it more my top three mods after a tune would be:

HPFP with whatever octane tune you can run
H&R Springs
AD TQ Mounts

That would give the owner the ultimate foundation. Good HP and TQ, better handling, almost eliminate wheel hop.

A good set of tires would be next, however most people don't think of those as a mod.

 

[stripSHO]

I tell anybody who will listen that buying a HPFP for e30 is a total waste of money unless you have other mods that significantly increase airflow capacity, but absolutely nobody will listen... lol

SM,

Thank you for your thoughts, a lot of hard knocks experience there!

What are the AD TQ Mounts? Are they the ones from Anthony?

No worries. It has been an interesting journey with this car. I have truly enjoyed it, and learning about it.

Yes the AD TQ Mounts are the ones from Anthony. They are one of the best performance items you can put on the SHO. However, they do vibrate a bit more then stock. Mine are broke in, and I don't even notice.

My GF who has no idea about the TQ mounts has never said anything about vibration's either.

 

[FrankK]

Thank you SM.

Lexus Update: So I bought a complete twin disc setup from SPEC Clutches. I priced out a complete McLeod Twin disc setup and it was $3300 before taxes and I would need to modify the front plate on my R154. Ouch. I read some good things about the Spec Twin Disc. SPEC says it will hold 900 lbs of TQ and is a direct "bolt in" so I pulled the trigger. It was $1796.56 shipped to my house. So yeah, going to start pulling the trans on Thursday. I will post on pics of the clutch and install later.

Have you looked into possibility that there's any aftermarket Dodge V6 5-speed parts available? After Toyota finished using the r154 they sold the design and the Dodge Dakota is one of the users of this transmission. It is originally a truck transmission and was improved upon in later iterations.
iirc the transmission might've even been used in the Pontiac Solstice and Saturn two seater sports car.

Might be something to look into later down the road. However, if my R154 gives the ghost down the road, it will be really hard not to T56 or auto swap it. Esp with the build I am planning, 600 hp to 800 hp will be easy to achieve depending on boost level.

There is also a shifter short shift kit available for for the r154. I had one. I could ask the friend, who now owns it as a parts car, if he willing to let it go. Mine to it shifts even more like a truck transmission with that. The short shifts were nice though.

Mine has one too. When I yank it, I will snap some pics.

Here is what is in the box. Looks pretty sharp .

Ooooooh, shiny goodness.

Ooooooh, shiny goodness.

Almost a shame to cover it, right?

Does it come with the display case?

 

[SM105K]

Haha no. I felt the same way with my McLeod when I installed it on my Camaro.....boo....
