Shifter23 Posted April 7, 2008 Report Share Posted April 7, 2008 Hey guys i just bought a 89 TGTP and am preparing to do a transmission swap and was wondering since i am pulling it apart what options for turbo and cam combos do i have? Is there any good bolt ons without needing total fabrication? I am saving for that topgun 160 setup with the cold air intake kit. Is there anything i can use with that without effecting what the computer wants? I am just wondering i bet this isnt the first time this has been asked but oh well i need to know. Like is there a turbo that would match a more aggressive cam but still work with program compensation. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted April 8, 2008 Report Share Posted April 8, 2008 t28/25 hybrid I've heard is a good way to go. otherwise, I don't think the TGP's have much of an aftermarket. I'm mid tranny swap myself right now, dropped the engine back in last night, but haven't reassembled anything yet Quote Link to comment Share on other sites More sharing options...
Shifter23 Posted April 8, 2008 Author Report Share Posted April 8, 2008 Ah thanks! but where to find one any suggestions? Also is that a direct bolt on or is there more needed to be done? Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted April 8, 2008 Report Share Posted April 8, 2008 Id worry more about the tranny holding up than I would upgrading an engine that stock can kill those tranny's. Quote Link to comment Share on other sites More sharing options...
TURBOLUMINA Posted April 8, 2008 Report Share Posted April 8, 2008 i can get you a brand new nissan t28 ball bearing turbo, originally on s15 silvias, internally gated from nissan japan for about $700. they are good for about 300-325hp Quote Link to comment Share on other sites More sharing options...
Shifter23 Posted April 9, 2008 Author Report Share Posted April 9, 2008 Hmmm interesting what other mods needed to make it work? On the trans when i get one i am investing into building it up to before it goes in i know better than that. Since it is apart hell do it all.

TURBOLUMINA Posted April 9, 2008 Report Share Posted April 9, 2008 i imagine it will bolt right in place. t25 and t28 turbos use the same flange design. And i believe the tgp used a t25 from factory correct? Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted April 10, 2008 Report Share Posted April 10, 2008 Correct, TGPs came from the factory with a T25. Quote Link to comment Share on other sites More sharing options...
Shifter23 Posted April 10, 2008 Author Report Share Posted April 10, 2008 So what upgrades are required for the T28? Injectors i suppose different cam profile? I am interested in finding out more also if it is internally gated how does that work versus the stock T25? Thanks for the responses keep it rollin i just hope my pocketbook will survive hah ha!

TURBOLUMINA Posted April 10, 2008 Report Share Posted April 10, 2008 it is internally gated. you would need injectors or just crank your fuel pressure. you could leave stock cam and somewhat keep your gas mileage. Just the turbo, injectors and a good exhaust will net you 300hp. By the way, i have 2 brand new sets of accel injectors. 24lb/hr and 30lb/hr. the 24's have a couple thousand miles on them, and the 30's litteraly 2 mins of run time. i had to run 42lb/hr injectors on my Z34 cause i was going for 450hp. the 24's would just support 300hp. the 30's will support around 350-375hp. either set, $150. let me know.

Addicted To Boost Posted April 10, 2008 Report Share Posted April 10, 2008 You will need injectors for sure. The stock injectors are maxed out as soon as you chip the car, so I'd imagine you need to step up to bigger injectors for a bigger turbo.

93CutlassSupreme Posted April 10, 2008 Report Share Posted April 10, 2008 I wouldn't change the cam on a turbocharged car. Spend your money elsewhere. Quote Link to comment Share on other sites More sharing options...
Shifter23 Posted April 11, 2008 Author Report Share Posted April 11, 2008 I am interested!!! One quewstion who do i go to to get that top gun 160 chip? I want all of his products including the cold air intake the thermostat, the two hoses he offers how do i contact if i get that i'll be talkin to you about that injector set the bigger one and to the dude about the T28. Thanks for briefing me in on not changing the camshaft. Should i get the plenum ported and where is the best for that? 60Degree.com will they take mine and send back?

GutlessSupreme Posted April 11, 2008 Report Share Posted April 11, 2008 I wouldn't change the cam on a turbocharged car. Spend your money elsewhere. Why is that? Just because it's getting air forced through it doesn't mean it won't benefit from lift and duration changes.. no, you don't have to, but it sure will wake up the powerband. The TG160 chip is no longer made, and Jeff M. hasn't been actively posting/selling for a long time. I suggest visiting tgpforums.com, there are several members, including the owner of the site (TGPilot) who are very knowledgable with chip editing and will sell a custom burnt one for you. TGPilot has his own shop where he could dyno tune it, if you're willing to travel, I forget where he's located though. I hear Ben (of 60degreev6) does very good port work, he knows his stuff. You can send your plenum and LIM to him to get worked over, it doesn't look like he does gen 2 heads anymore though. Many N/A 3.1 people have swapped to gen 3 heads and intakes off of newer 3100/3400s (even 3500s now, I believe). Stock, a 3400 heads flow as good as some of the best fully ported 3.1 heads. A lot of turbo guys don't want to lose their Turbo Intercooled plenum though lol. You can't upgrade to the newer heads without using the newer intake manifolds. That, and you pretty much need a turbo upgrade when you move up to the newer topend because of the flow increase. There are lots of topics detailing that between here, tgpforums and 60degreev6. Use the search button. Quote Link to comment Share on other sites More sharing options...

Just because it's getting air forced through it doesn't mean it won't benefit from lift and duration changes.. no, you don't have to, but it sure will wake up the powerband. You are correct, but a higher lift cam won't benefit a turbocharged car as much as it will benefit a N/A car. A cam on a turbo engine isn't as cost-effective as other upgrades. The biggest advantage to a larger cam (and better heads and intake for that matter) is the same amount of power at lower boost pressure. Most production cars have the same, or very similar cam grind, to the N/A version of the same engine. There's a reason for this. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted April 11, 2008 Report Share Posted April 11, 2008 yeah if you put a custom cam in your motor, youll need new pushrods, new springs, probably new lock/retainers, and new spring seats. This is not very cheap. Quote Link to comment Share on other sites More sharing options...

This is not very cheap. My point exactly. Put that money towards a better turbo, or a transmission that can actually handle the LG5. Quote Link to comment Share on other sites More sharing options...

This is not very cheap. No, you don't.. if you get a wicked radical cam profile with high lift rockers, then yes, you'll probably need custom length pushrods. You don't have to replace the entire valvetrain though When I did my rebuild I went with a mild Crane H260 cam and 1.6 ratio stamped rockers off a ~95ish 3100. I replaced my springs, seats, retainers etc with new pieces because I chose to upgrade to much stiffer LS2 or LS6 valve springs to help with valve float at higher RPMs. Those are not required upgrades, but they certainly couldn't hurt if you have a high mileage motor with worn out springs. You don't want to go too stiff with springs, it'll put a lot more wear on the cam and lifters since none of our stuff is roller.. Quote Link to comment Share on other sites More sharing options...

You don't want to go too stiff with springs, it'll put a lot more wear on the cam and lifters since none of our stuff is roller.. Anytime you change the cam you need custom pushrods to keep the preload on the lifters. Thats one thing Ive learned about building my motor. You also match the springs to the cam as well. Like the cam I have, LS6 springs are recommended. And since you cant use the stock spring seats you need the LS6 spring seats. Although you could have gotten away with the stock locks/retainers, I went with CompCams. But still You need to change said things if you want everything to work like it should and not have a valvetrain that will get noisy over time and not function like it should. Although it will "run" it will not be optimal without said things to acompany the cam. Quote Link to comment Share on other sites More sharing options...
TURBOLUMINA Posted April 11, 2008 Report Share Posted April 11, 2008 Turbo cams are much different than a N/A cam grind. Boosted cars dont require lift changes necessarily. Its all about duration. He isnt trying to build a 600hp car here. He is just looking for an upgrade. My Z runs beautiful with stock cams and just some porting. Let the turbo do the work. Just the T28 upgrade and some injectors with a nice front mount intercooler will be more than enough for him. And it will idle nice and still get 25mpg just cruising. He dosent have much money to spend as stated in the post, so why go blowing money on a cam and everything else with it?? Quote Link to comment Share on other sites More sharing options...
Shifter23 Posted April 11, 2008 Author Report Share Posted April 11, 2008 Thanks that is what i am talking about. I am looking for 300-400h.p. a street brawler not a monster. So the T28 with bigger injectors. On the Intercooler any suggestions? On the chip i will talk to the people suggested. Intake and exhaust upgrades obviously on the transmission i posted a thread on a possible swap with a 282 Getrag. Any suggestions on that or the automatic hit me up there. Thank you for all suggestions please keep it up since your advice with directly effect this cars build. I am new to turbo builds so this all is very helpful.

Shifter23 Posted April 11, 2008 Author Report Share Posted April 11, 2008 Also guys any suggestions on cold air intake setups anyone know where to go to match one up since they don't make one that i know of. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted April 11, 2008 Report Share Posted April 11, 2008 Stick a K&N on the turbo, you will get MUCH better airflow than stock, but it won't be very cold air. Quote Link to comment Share on other sites More sharing options...
TURBOLUMINA Posted April 11, 2008 Report Share Posted April 11, 2008 http://cgi.ebay.com/ebaymotors/TURBO-INTERCOOLER-22x6x3-Eclipse-Talon-RX7-RX-7-300ZX_W0QQcmdZViewItemQQ_trksidZp1742Q2em153Q2el1262QQcategoryZ33742QQihZ017QQitemZ270227532470QQtcZphoto This is the intercooler i am running on my car. it worked out awesome. Because the inlet and outlet are on the same side, it keeps your charge pipes as short as possible for boost response. It will support twice the horsepower you are looking to make. I ran the upper pipe right through the front bumper, and up through the battery tray as you can see in my avatar. Quote Link to comment Share on other sites More sharing options...
