Default PE1820, sti injectors, supra fuel pump and turboxs unichip install

Well kids my days as a stock turbo wrx are over. Last night i installed what may well be a turboxs stage 3 or 4 kit. Everything was a direct bolt on other than the BPM large inlet pipe... that was not the best fitting item i have ever used, but we got it in..

Anyway it took a LONG time to do everything at once like that, but when it was all said and done, we turned the key and the car just purred.

No idle issues, no driving issues, nothing. I started playing with the boost.

Started at 10psi... nice (pulls as hard as my old setup)

moved to 12psi... big grin

moved up to 14psi man thats fast

Cranked the boost to 16psi nearly had to change my shorts

cranked it to the 18psi the map was tuned for; HOLY CRAP!!!!!!!


i am at 5600 feet, running 91 octane, so UMMV, but 1 bar of boost arives at just under 4000rpms in 2nd gear (lower in 3rd and 4th). Happy land starts at 3500rpms and pulls like a freight train to redline. Second gear feels like my old frist, and first is just NASTY fast! Once the turbo starts to spool, it comes on so quick. On the stock turbo if i punched it from 3000rpms, i could only manage 14psi in frist. On the new turbo its hitting 17.8psi just as i shift. When i pull it into second, the car hits redline so quick and its time to shift to 3rd before you can even enjoy it you can go from 4000rpms-7000rpms in 3rd so quick, and even 4th has some serious pull now.

The car is a whole new car, and when boost comes on it feels like God gave it a good kick in the backside.

Just think, there is another 40whp in the little chip i have sitting in the back seat that is designed just for race gas

I have not launched the car yet, but so far the clutch is holding quite well... then again, when i do launch, i don't really do the major clutch slip action that some of you are fond of...

The race to 11s is on...



Mark, i can not say enough good things about your tuning. I am totally impressed! My friends (who know the car well) were all grins from ear to ear when we got to go for test rides, and all of them were shocked at how much difference this round of modifications made.

That rocks!
Last we talked I left the conversation under the impression you had settled on the 18. Nice to see you getting good results; fraternally bound with the rest of us 1820 heads. Not likely to see fruition of my build for more than a month yet! A little jealous...

Ya, it all started when i took a ride in my friends talon tsi. He has a Gpumper 60-1 on there, and after that i felt that any lag i had to deal with would be no big deal.

The car just rocks with an 1820, and i am glad i went with it not an 1818. The 1818 would be a better turbo for autocross or road course work, but i can deal with the lag (which by the way is not that bad).

MKIV (93.5-98) supra TT's have a denso fuel pump that flows 255l/ph

Talk to adam at Z1 performance he can get you one.

Sounds good, but what is the deal with the Supra fuel pumps? Their size? What year? Cause the latest Supra pumps leave much to be desired. Some of them go to the 90-96 Nissan 300ZX fuel pumps to get more. I would think since they have been around longer and sold more(300ZX).... people would use them, finding them easier and cheaper at junk yards.

Ummm....what are you talking about. Stock Supra pumps are good for 500rwhp.

I think the 300zx is good for 650rwhp...i could be mistaken

I personally had twin stock supra pumps....good for 1000rwhp, but I was only doing 687rwhp. A supra pump will flow more fuel than a nodded WRX will need.

BTW, whats the price on the fuel pump with filter...i think I paid around $200.00 for mine.

Wow, can`t wait to see your times.

What is in store for your tranny? Upgrade wise?
Are you still running the stock intercooler?
I`m jealous.

The MKIV Supra fuel pump should flow enough until someone starts thinking about some major hp, likke 500+. Personally, I've also been wondering about the MKIV Supra injectors. They are rated for 550cc, and are made by Denso, which I've seen being sold here. It would be great if they just dropped in like the STI injectors, as they can be gotten for about $250 for a set of 6. Hopefully someone has access to both cars and can get an answer on this.

$75-$100 at a junk yard and easy to find in bigger cities. I would imagine you could find the Z pump cheaper at the yard (more Z's sold=more wrecked). I have one lying around I planned on using it. I was wondering why I kept seeing posts about people using one from the Supra. If maybe it had some benefit to the WRX. I know multiple guys with Supras using the Z pump in higher HP setups, but yea, I'm sure either one would supply enough PSI and flow.

Nathan - did you go down to turboxs - OR - are you just using my program ??? If so - on Willie's car - same set up - it didn't run very well at all!!!! Seems that the cars have some individual variance !

Mark has a pretty good idea of my setup, and the program ran not just well, but awesome. No knock, EGT'S nice and safe, and the power is awesome.

I am quite sure that mark could get some more HP out of the setup, but i have to wait till after SEMA when i can get him out here to do the tuning at a AWD dyno in bolder, CO.

This does however make me wonder about whats the deal with Willie's car...

Willie's car has all the same stuff as mine - I set it up as a duplicate - mark sent me up a direct copy of my program and compared to my car it ran very weak - every WRX is a different bag I think - but the drag strip numbers will tell the story - - - sadly I wont be doing any racing any time soon as I have too much power for the stock clutchj to handle right now . . think I'll just ride it easy and shift smooth until someone can break my record ! (i know this set up I have now can get under 12.5 and over 112 in the 1/4 with no sweat if i wanted to risk breaking the trany and putting and end to teh clutch which was slipping real bad when i went to the strip on friday)

I hear you on the clutch, i have not launched mine yet, just in gear pulls, but so far on the pump gas map @18.5psi i have no slipage in 1-4 gears.

The race gas map may well put it over the top though... i'll find out soon.

This car is just insane compared to my old setup, and that was good for a 13.2 on pump gas...

Interesting to note that my car works better with the street unichip and the race gas at 20 psi then the race unchip - weird eh??? Also - after 19psi my 1820 starts to make very unique turbo sounds - let me knwo about yours!

I have not yet heard that sound, but i'll let you know soon. I should be trying the race gas map very soon, and with any luck i'll make a record attempt next weekend.

I should also note that if AL's results or my results have prompted anyone to want to get in on the action, they should call mark for the unichip, and i think Jan Shim also still has access to a few of these turbos.

I'm working on it as we speak..got a line on 3 bxes right now....2 are older STi units (one V3 RA and one V4), and one new '02 WRX one.

The V3 RA is what I used in my own car...not as strong of a casing as the later moel units (v5 and V6), but the gears are very strong (as compared to an '02 WRX), and all you need is the box and a new clutch line. The later model ones use a 4.44 internal ratio, so you need a rear, axles, etc....I personally didn't mind the added cost, but 4.44's on the street would not be fun IMHO...too high revving,. But for those mountain roads, it would be sweet..always in the power band. it's a good match on an STi motor though, as they are higher revving and generally higher strung than the standard WRX.
