HI....

i have corvette c5 zo6 2003 with aps twin turbo and i need to get bigger or upgrade the turbo

if any one have information please let me know

chris.shea

Mitsubishi/APS single entry T3 frame size .84 A/R turbine housings with external waste gate port/provision and APS designed and manufactured .65 A/R compressor housing.

Whats the part number on the stock turbo anyways? If you can fit a better flowing t3 down there the first problem you will run into is the turbine housing is custom cast for APS. Been watching your vids on youtube btw.

LG sponsor on the site is doing stuff on the aps turbos.

Been watching that as well. Peter wont respond to my pm about putting the C6Z06 kit on a c5. I know DTE has installed the base c6 kit on c5's(pre c5 kit production). They even said they did not have to hammer in the frame rails either.

Do you mean rebuilding them or doing something with the kits?

I wish they were more reliable. APS I mean.

On a thread in the corvetteforum LG stated they are using new center sections in their C6 kits they are modifying. Cant speak for reliability i have not seen anyone post a corvette turbo failing yet. Did see a few posts on the fobdy kit though.

I could have swore APS did GT35's on the test C5Z06 they purchased....

chris.shea

They did. Peter told me you can upgrade to the larger turbos but a new smaller starter is required. I missed the deal on CF 4sale section over the weekend i guess... should have sent my brother to stop by the shop with a check this weekend.

Reply i received yesterday from Peter.(sunday here, Monday there?)
APS has not spent any engineering time on larger turbos for the C5 system as it's not our highest priority at this time. That said, the larger 65 lb per minute turbos that we packaged for the F body should fit up on a C5 though you will need to install a smaller MSD starter motor to install the larger turbos.

its funny this just came up id called LG yesterday about getting bigger turbos for my f-body. i talk to louis about what i wanted to do. he was very willing to help. im waiting on some spec he is sending right now i would just give him a call.
as for APS i will not deal with them anymore do to the poor help that we got when turbos started to die and inlet ducts start to suck shut. LG Motorsports is the way to go at this piont.

Definantly talk to Louis at LG. I think the cost to upgrade to the larger turbos is $1100. ($550 per turbo)

Prices have gone up considerably since we started this, only because I will not reuse the APS Center housings. Thats where the problems have stemmed. Base 60lb/min turbos start at 2200, and go up from there, all the way to an 80lb/min wheel.

I can also fit a GT35R wheel in there as well, but my wheels are much more efficient than a standard Garrett 35R wheel.

Ive been absent on this board for almost a month, I apologise, any questions you have, feel free to PM me. Tom, are you home yet? My guys have your info, Ill shoot it to you tomorrow when Im at the office.

What are all your upgrade options for the f-body base turbos? Can you give us a list of each option with hp potential and price for each?

Have you found manufacturing/design problems with the APS hardware? PM me if you don't want to post please.

I have 4 upgrades available- KEEP IN MIND stock 20Gs flow 44-46 lb/min

76HTA- 60lb/min- $2200
GT35- 65lb/min $$TBA
82HTA- 70lb/min $2400~
88HTA- 78-80 lb/min $2800~

The 76 and 82 HTAs require some finesse with the inlet tubes, as its a bit larger than stock, but we made it a very tight, yet doable fit. We needed the room for the compressor wheel.

The 88HTA is a mean bitch. Having said that, it needs more inlet opening. Im having some updated covers fit and some reducers/adapters made to fit them to the stock inlets.

Ill PM you later on today about the stock stuff

So does this mean you just sell new center housings now to drop in don't need any exchange. Or do you sell complete inlet ,center and exhaust housings ? Not following too well. So these are 2200 per turbo? Are they made of gold or something if that is for one turbo?If its for two new centers fine and with new inlets yeah could see being a bit more. Quality 20g centers cost like 400 US , so the work to add in the new wheels could be 1200 US maybe,Forced Performance is a good shop.

But really there is nothing in a turbo. Some wheels,shaft,c clips, housings they are simple things. APS must be using Chinese center housings .20 G mits centers are normally good for 100,000 thousand plus miles. Have run them in my talons with zero problems.

You can get gt35s complete for like 1500 bucks, intlet and exhaust housings. Now if that is price for two not so bad.And would assume its new center and possibly new inlet housings. Can't see getting 80lb/min without going up to bigger inlet housings. Can possibly see doing 60lb/min from standard housings or maybe machined out standard inlet housings?

Can you explain a bit clearer. If the upgrade costs are indeed 4400 for both think will stick to my recently purchased ebay center cartridges made in Japan with supposedly newer wheels and
use some spray if want to hit 1000rwhp. If the 60 lb/min is 2200 for both then could be upgrading possibly.

Anyway its nice you are giving us options. Please clarify the pricing and sorry if took it the wrong way.

Cool, thanks Louis. I'll definitely be giving you a call when the time comes.
I'm sure those prices are for both turbos.

Correct price is for 2. You are getting a pair of DROP in center cartridges and compressor covers. The turbine housings are APS Specific I cant supply those, nor can I buy the larger AR from APS. Ive tried. Nor can I buy the C6Z GT35R turbos/turbine housings either. They fit, but I cant buy them. I tried that as well.

You can keep buying cheap stuff and not having the reliability and warranty, or you can do it once and do it right. I end up picking up the pieces of so many failed combos its not funny. I can only give you the choices, its ultimately up to you in the end

Ok that is clearer for two. Much better. So we don't have to send in anthing just order the new parts plug and play since they are simple v band setups?

So no exchange needed we can then sell off our old center sections. So to be clear these are going to work with the standard inlet tubes but the 80s will need reducers if they use a 3 inch compressor cover? Is that pretty much right?
