Good turbo for track and drag use

[blitz43]

hey guys,

I've been searching around the forums for answers but everyone has their own opinion and i can seem to get a solid answer about it so i'm putting up this thread.


I'm looking for a turbo thats pulls from mid to high range in the rpm band
and is great for both drag and autocross/ track use

my current mods are
2.5 to 3" downpipe
no cat
3" cat-back
full upper intercooler piping
255 walbro
afpr

getting maft soon

also need help in deciding what injectors to go with the turbo chosen
thx

It depends, what do you want the car to do HP wise?

I'd say EVO 16g, skip the MAFT, and get an EPROM ECU and DSMlink with some big injectors (car will run like stock with 950s using Link). You may also want to look into a bigger IC, even a larger SMIC would help.

If he is road racing, he will need a fmic. And a new radiator to run boost for an extended periods of time. a Front mount though will help out alot.

There is a lot of tubos out there that make good midrange-high end power. Do you plan on an intercooler upgrade soon? If not i wouldnt go with more than a 16g, if you plan on doing a front mount setup...skies the limit! For autocrossing, spoolup is the key. For drag racing...not as big of a deal. A happy medium would probably be a 50 trim setup. It has pretty good spool up time (especially with a blowthrough setup) and makes good high end power. You could easily do over 400 whp on a 50 trim. I would suggest a 750-780cc injector for that setup.

sorry forgot to put on that part about the fmic and hp range

i thinging of getting the either greddy 24 big fmic
or the apexi

i have dejon full uicp to the throttle body and i believe the apexi with that


also thinking of getting fal fans to keep things cool

hp wise i want to get about 350 to 380

98 gs-t automatic

after the turbo setup i'll be looking in getting an ipt trans casue i think it said that the 2g autos can handle only 320hp ? not totally sure


so a 50 trim would be a good choice?
which one to be exact i know there are alot of makers of that type of turbo.

which ones would you guys perfer?

what kind of tuning because i dont think the s-afc can handle that high of injectors

would the maf-t handle it?

 

[SBR Joe]

SAFC will be fine...my FWD has 780's with just an SAFC andi drive it every day.

Thats weird I was always under the impression 650s were as high as you would want to go. With that big of an injector you would see enourmous timing advance which in turn horrible knock issues.

Nope, i wouldnt reccomend higher than 780's though. Bigger than that you need DSM link or what not. But im fine with just afc.

autocross and drag/roadrace are kind of on opposite sides of the spectrum, fast spool and power. I have had very good luck with the e316g, fast spool and great power for a DD. I would look at either a dsmchips or dsmlink, have used both and much easier to tune and drive. I personally don't like the maft, have had many friends that had them and all got rid of them, and with your power goals stay with the 2g mas.

The MAFT is a PITA to tune with, but with an afc you dont have too. On the maft just set the injector settings and leave everything else zeroed out, and fine tune with the afc. The maft is much better for airflow and spoolup time (as long as it being used as blowthrough, not pull through.) So as long as you got an AFC...keep the MAFT setup.

I'm a fan of Garret Turbos at the moment, with ball bearing turbos being towards the top of that list:

the Garrett Ballistic Concepts Racing GT35R Ball Bearing turbo seems to really put down great high horsepower numbers. I've seen respected tuners use this as a must-have on their DSMs. The bummer is that they are at least $1200 plus you will need and external wastegate, a different o2 sensor housing, and a different exhaust manifold, not to mention an IC.

so, heh, but what's more important than naming a brand off and saying it's great (I only did because I want to replace my BG16G with it..) is finding out what YOU really want, what your budget is, and how much of this job you want to do/research yourself

1. Do you go to 1/4 mile tracks more than Autocross?

2. How much do you want to spend on your turbo project?

3. Are you going to want to install this all yourself? and if so, how much experience do you have installing turbos. (this could mean you might want a easier kit or different turbo to relieve the stress of the install)

4. And lastly, when/how fast do you want to have your car done so you can have it at the track? (I only say this, because... my car, is meticulously done and fast, and sitting on jack stands for over 6 months in my garage )

That depends on how much boost you run and compression though. I gauruntee you he going to have trouble on a 2g running any decent amount of boost.

While thats a great turbo, I don't think its the best choice for autox For a great all around turbo I would recommend the FP3052 & if thats not in the budget a bolt on 3076 (such as PTE, Bullseye, etc) will also do the trick at a cheeper price. Then there is always the good old 50 trim, thats makes some nice numbers. This in a BB version should still meet you autox needs.

As for your FMIC choice don't waste your money on Greddy & I wouldn't on Apexi either. Nowadays there are much better choices. For around the same or probably slightly less you could have a SBR kit which is a tonn better then the Greddy. I would recommend the Victory Performance kit as this is what I run & the build quality & performance is amazing but I don't believe there still going. If your looking for a cheeper route go with the "Ebay" fmic setup, there are a couple hunge threads on here & they seem to perform very well for the cost.

EVO III 16G. That's the biggest turbo you should go with.

Tuning 780cc's with just an AFC eh?

 

[jazzyjay]

I run a S-AFC with 950 injector and DSMchip with no problem. If ECU is chipped for the injector size the, S-AFC is only used for fine tuning.

im at 25 psi stock compression.

Yea. E16g for dual purpose. Road race it on Saturday, add C16 on Sunday and run your 11's at the drag strip.

Lets see some datalogs.

Well...there's a BIG difference if your ECU is already chipped to compensate for the injectors. There is NO way you would tune that car if there was no chip on an safc alone with those injectors.

I agree 100%

 

[blitz43]

so 650's and a 50 trim ....pte5031e?
what kind tuning? dsmlink or afc?

 

[fwdeclipse]

If you have the funds then DSMLINK is a no brainer.
