i have been debating on which system to go with for about a month now, and i think i have pulled the trigger on the greddy one. Not just because its cheaper by a couple G's, but because i have had greddy kits before, and they seem to work very well. Although i have heard the most problems comming from this kit from any other kit out there, more motors seem to be blowing from this kit than any other, but is that because this kit is the most widely used kit on the market?? therefore it will have the most problems. The APS kit i have heard only good news from, horsepower from a stock motor w this kit is over the 400 mark, which is excellent. Greddy kit i think is somewhere in the 350-380 range. Whats the decision with most of u guys out there????spend the extra 2-2 1/2 G's for the APS or build motor with that 3 G's and boost more with the greddy?????lookin forward 2 the input guys. Thx fellas

 

LOL, i love these threads......easy reason why you should get a greddy kit....very tuner friendly, almost anyone can tune. You probaly will upgrade all the APS TT kit fuel stuff anyways. PLUS YOU CAN GET OPEN WASTEGATES FOR UNDER 300.00...a greddy kit with open WG will own APS kit, on low boost....I said it...Im done...Kenji...you owe me

 

Some people will tell you

"stock block/internals are good for XXX hp"

others will tell you "engine can blow at any boost level / hp"

Whatever you decide, I would suggest having a good $7-10k in cash ready for incidentals.

 

true....true....but ball bearing turbos vs those mitsu turbos seems kinda like a david and goliath mismatch here.....or am i way off??????

 

Its a great question and I know what you are going through.
I have yet to find an answer though. It really is just a matter of which way you want to go. They both have very good aspects. I like them both very much. I can't decide. All I know is what everybody else says. The APS is a very clean and complete install. I don't want to get crazy numbers here. I would be very happy under 450 whp. We'll see and good luck on your search...

computer F***** up and posted like 3 responses....sorry guys

 

have you considered the JWT TT also?

 

I am sorry, but if you are deciding between Greddy and APS, then JWT should be excluded by default. If he went between APS and PE, then maybe...

 

i think im gonna go w the greddy kit,im gettin it for 5800 w intercooler and shipped, and im gonna use the other 3 G's for rods and pistons, and going to pick up cams, springs, pullys, and a plenum, hopefully ill b able to boost about 12-13 pounds safely and get about 420-440 to the wheels

 

Nice choice on the kit, but for 12-13 PSI you'll need more then 440cc/fuel pump/e-manage blue to keep your motor together....

 

yaa im lookin at some 660cc or 680cc injectors, a walbaro 250 pump, i think thats the name, and the E manage from greddy, i want to go stand alone tho, link it 2 my lap top in the cockpit, but i guess 1 step at a time.

 

are you doing the install yourself? TT Kit and Engine work?

 

I have a Greddy TT for $4k.

 

you can get 440whp safely on the stock block with both the greddy and aps kit. if you do it with the greddy kit it will require additional parts that do not come with the kit....fuel system, better EMS (Emange Ultimate or UTEC, fuel pump, and BOV. After all is said and done and you buy the needed parts for the greddy both kits will be about the same price. If you go with the UTEC with the greddy it will cost you a little more than the APS, but you will have a better EMS and fuel system than what the aps brings. Both kits are great although the greddy is not complete out of the box. The APS brings water cooled ball bearing turbos that supposedly spool faster, but with my custom dump tubes I hit full boost at 3700rpms just as APS claims with their kit. I prefer external wastegates like the greddy kit has over the APS internal wastegates.

Most important thing for the greddy kit is to find a competent shop to do the install and tune. The APS is more idiot proof than the greddy.

 

Thx 4 the input Gman, i c u got the kit on yours, how do u like it??? how much power u puttin out??? how much r u boostin???

 

naa im not installing it, the guys at brainstorm r puttin it in 4 me, they gotta a lot of cred. and they have put out some crazy Z's and G's

 

well i was looking at your numbers... and i know it takes $10k to $12k to do 440 whp safely with gauges, fuel, engine management.. tune..etc.. another $5k to do internals and such..

did they give you a quote already?

 

I've been through a lot.....2 blown motors, but not the kit's fault. My problems came from my installer. He bent my stock rod on the dyno and then with my built motor did a horrible install which caused me to fry 3 piston. I shipped my car to SGP for the 3rd motor and tune and I couldn't be happier. I wish I would have shipped my car from the get go. I am running 16psi and dyno'ed 513whp and 480tq on a dyno dynamics with no correction factor. dyno dynamics read at least 10% less than dyno jets.

 

what are you power goals? if you don't plan on going past 480whp I would just go with the APS since brainstorm is an authorized APS dealer. You can get past 500whp with the out of the box APS TT kit, but it will require upgrades, fuel system, injectors, EMS (some shops have gotten the Unichip to work for 550whp, but not many). For hp goals more than 550whp I would recommend either the greddy or APS tuner kit.
