TC 2.3 questions

November 09, 2011, 07:19:40 PM

alright, since i'm getting this new TC with the motor/trans, i have some questions. i don't know what's done to it, if anything, besides the boost controller that's ziptied to the passenger side fenderwell.

the guy said it pushes 23psi according to the gauge, it that safe for a stock motor? seems like i bit much to me, but i'm new to these so i have no clue.

what's the best size to run for the downpipe? while looking under the car, i saw the exhaust is pretty rusty and it has a couple holes in the tailpipe.. so i'm considering replacing it all, including the downpipe, cat and ler

If you're trusting the factory gauge, don't. Get an aftermarket one and see what it says. If the turbo is still the factory IHI, 23psi is suicide/almost impossible. All it's doing at that point is putting out hot air and getting ready to self destruct. If it's been swapped for a T3, 23psi is at the end of it's effeciency range. 20-21 psi would much better for T3 turbo life.
As for exhaust, go 3 inch or go home.

has an autometer gauge in place of the digital clock.. i don't know a single thing about the motor, neither does he. i basically have to pull it apart and see what's what (not that i'd really know what i'm looking at under the valve cover lol)

thinking of putting a T3 on it.. there's 1 in the junkyard i've been eying up everytime i go.. never really had the time to try and rip it out.. or a reason to, until now lol i don't really want to hit max boost before things break, but i'd be satisfied with 20-22 with a FMIC, a little porting and ranger cam.. might pull the head off and clean it up, check it for cracks or wasted valve seats just to be safe

I didn't notice what year your TC is, but if it is "87/88 here is article for installing a T3. If it is "86 or earlier it already has a T3. http://www.turbotbird.com/techinfo/Installing_T3_on_87-88TC/Installing_T3_on_87-88.htm

Hope this helps.

Shadow if you want HP better not consider the RR cam. If you are going through the trouble of pulling the head and checking the exhaust valve seats for cracks.(they most likely will be). You are wasting your time and money on a cam that could not pull a fat girl off a bike. I would suggest a cam with more GUTS. The RR cam is actually smaller than the stock slider. Good luck on your build.

really? thought the ranger cam was a 'hot upgrade.' this is why i love forums, i would have been pissed if i found out the hard way.. lol.. what's the going rate for having valve seats done?

Shadow here is a cam that i use frequently that will wake up that motor like GANG BUSTERS. It has a strong mid range and buzzes right up to 7K. I see you are in NJ so i dont know about a tail pipe test their. This cam is clean but not capable of passing SMOG. Good Luck.

unfortunately, i have to keep it sniffer legal, since we have inspection in this state, as well as delaware.. so either way she needs to play kindly with emissions laws >:l

thanks for the info :burnout:

My machinist charges $12 a seat for install, I provide the seats. If you want to run a cam with over .450-.470 lift, you'll need to have the top of the guides cut down for proper clearance.

thanks, i'll keep that in mind.. i doubt i'll go really big, maybe a bump or 2 over stock.. valve seats are pretty cheap.. at roughly $12 a pop, i should be able to sneak away with buying them and having them installed for just under $100, plus the cost of gaskets/new bolts to put her back together.. sounds pretty good to me!

Uhmm, you've left out the cost of the valve job that'll be needed after the seats are installed. In addition, factory springs are marginal at best, totally inadequate with a better cam, better figure in the cost of those, along with new guide seals. All of this assumes the actual head itself isn't cracked. If it is, which it probably will be, the cracks may be taken care of with the new seats if the cracks are small enough. If the cracks are large, and unable to be taken care of with new seats, you'll need to find another head.
As far as costs go:
Seats: $20-$30
Install: About $50
Valve job: $100-$150
Springs: $50 on up (You can pay more if you want, but the ones I run for a mild hydrualic cam run $50
Valve seals: $25 for good quality Viton seals
Cam: Choice is yours, but I wouldn't run anything but a roller. They can be purchased from various sources: Schnieder, Engle, Bo-port, etc. Expect to spend upwards of $400 for a cam and proper roller followers. Everyone dogs on the Ranger Roller, but for a person on a tight budget who wants a roller cam, or someone who's slider cam is wiped out, it's not a terrible choice. It has good manners, a strong bottom and mid range, and it's a roller. It's just a little weak on the top end, runs out of steam around 5500.

I would probably recomend one of boports cams. The 1.5 I have in my autox car will pull easily over 7000(seen 7500 more than once) and thats on an unported head. I have a 1.9 in my burgundy car and it would probably be great if it had a slightly smaller turbo. The 1.9 is actually alot bigger cam than I thought it was going to be. It idles at 9in vac. The 1.5 is 16in vac.
