i've heard a tII exhaust mani will fit a 12a but will it fit a first gen 13b?

 

yes, there is no reason why it shouldnt.

 

Yes, it'll bolt to an early 13B block. However, there are intake manifold clearance issues you have to take into account.

By the way, a TII exhaust manifold won't fit a 12A without modification.

 

how much could you boost a stock 13b as a daily driver?

 

That depends on a lot of things. What turbo? What size injectors, and how many? What intercooler setup? How well tuned is it? How much attention to detail have you paid in fighting heat?

 

i guess what im asking is with a completely stock 13b with a stock second gen turbo with a small front mount intercooler how many lbs of boost could i push without doing damage?

 

the turbo is limited to about 14, from what i hear. but you could make more horsepower on less with a slightly larger turbo. pick how much hp you want, or pick how much money you want to spend, and we'll make a recommendation.

on a side note i would like to make a graph, plotted hp vs. cash, and give realistic figures.

 

well im on a seriously tight budget which is why i was asking about the stock second gen turbo. so would the totally stock engine be able to handle the 14 psi?

 

The engine can handle it just fine... IF you can keep things cool and feed it enough fuel! Stock, you have just two 680cc injectors (I'm assuming you have a GSL-SE here), which ain't gonna cut it. And you need a tunable ECU and someone capable of tuning it well.

 

you can always port match a t2 intake mani to fit your engine and should have no problem with the turbo clearing it, you will also get a place for 2 extra injectors to handle the fuel for the boost.


edit: im running a 88 6port with t2 intake port matched to the block, upgraded fuel pump, s4 turbo at about 9 psi , raising rate fuel pressure regulator, volvo intercooler. im not running the GSLSE fuel injection im running all t2 electronics rtek 1.5 ( soon upgrading to 2.1)

it is said that the stock turbo isnt really that effecent after 10 psi, but you can always do a bnr 1 or 2 and make almost 300

 

Quite honestly Joe you're asking some pretty rudimentary questions..... questions that you should have a firm grasp on way before ever contemplating a turbo build. Do yourself a favor and do some homework before you start spending any money. Turbos and rotaries do go together like apple pie and ice cream but apple pie doesn't blow-up if you don't put enough ice cream on it. Long story short turbo projects are not cheap, and if you do it on the cheap expect to spend money elsewhere, like your engine when you detonate it. Weather you decide to go carb or efi they will both require a wideband to tune and a VERY solid knowledge base, and the margin for error is pretty narrow when it comes to breaking apex seals. Just my $.02.

 

well im picking up a gsl-se in about a month and i found a stock tII exhaust manifold for sale so i figured i'd ask. so could i just bolt on a stock second gen turbo and boost about 5 to 10 psi?

 

Not that simple. The TII has 4-550 cc injectors, staged as primary/secondary injectors. The SE has 2-680 cc injectors, so It's short on fuel supply from the start just by adding a stock 2nd gen turbo. Before you buy anything else, read up on turbo/hp upgrades in the 2nd gen forum. The 2nd gen turbo will not clear the S3/4/5 NA intake manis. You either mod the exhaust mani or find a TII intake system.

The SE ECU is not set up to handle staged primary/secondary injectors. You will need to find a complete 2nd gen engine harness for intake you swap in or go with a stand alone ECU.

If you're on that tight of a budget, this may not be the path for you. It can get expensive quickly and mistakes have proven to be even more expensive. Resulting in the end of many projects due to the lack of knowledge and cash reserves.

 

I agree.

But the gsl-se and manifold you are looking at could come in handy. You can always buy it and sell it later.

Research like crazy, and if you find that a good turbo build is out of your budget, sell it. If you want to do it, you will have the parts handy.
