ok im tired of all this talk about droping a turbo into a n/a.. so im just going to buy a T2 engine and drop it in my car.. since my car weights a lot less then a turbo and ive doen weight reduction and i dont wanna go out and buy a T2.. ive done to much to this...
ok this is what i wanna know all i need is a T2 engine, T2 Tranny, Automatic Driveshaft, that should be alright and its just drop in... i would love to hear what everyone has to say i have a 87GX, should i look for the 89+ T2 engine or should i stick with one from the same year? thanks

 

major pain unless you buy a haltech. probably less then a turbo ecu, wiring harness, AFM, boost sensor, etc anyways.

the auto driveshaft is a myth. either get the turbo rear end or a custom driveshaft.

 

so a T2 ecu is more than a haltech? how much am i looking at for price if i can get an engine out of a junkyard? or j-spec? but ive heard good and bad things about those engines.. if i get the T2 engine and ECU out of a car at a junkyard then why wouldnt it just bolt right in?

 

no.... unless you got haltech. not only do you need to find a turbo wiring harness (good luck..) you also need to change the harness under the dash.

and that's for putting an 87-88 turbo engine in. an 89+ would probably be alot more work.

what harness under the dash...

Procedures:

Remove your old engine per the engine removal/installation procedures.

Remove your old ECU, pressure sensor, throttle cable, fuel pump, and front half of the exhaust and install the new parts.

Pull your old NA flywheel off and install on the new turbo engine. Pay attention to #1 in Parts list.

Install your NA clutch, transmission, and install the engine into the car.

Install the knock control box.

Install the exhaust.

Modify the stock hose routing on the firewall to accomodate the new T2 vacuum outlet for the brake booster. You can either use a longer hose, or cut the existing metal pipe.

Install the turbo hood

Install the boost gage.

Have fun in your new conversion, but avoid being hard on that small clutch, it cant hold a lot of power or abuse.

Seems pretty basic...
if i found a T2 in a junkyard with everything would it be easyer? instead of going around to find everything.. time to find me a turbo! any other suggestions Scott?

 

i guess i would need to do the whole fuel system.. what would u recommend for that.. could i just get a T2 pump and injectors?

 

no suggestions.. has anybody dont this on this here? i figured it would be easyer then putting a turbo on a n/a...

 

Well you will need the TII fuel pump and injectors if the engine doesn't come with it. You can find walbro fuel pumps alot of times for sale for like $100 and you will not have to worry about upgrading later on.

 

so all i need is the engine , wireing harness , tranny , custom driveshaft , fuel pump? throw all those in and get it running and it should be good with that?

 

Ya you should be good with that I think. There are alot of threads on how to do this. Hate to say it but have you tired searching?

 

yeah i know there is a lot of threads about putting a turbo on a n/a.. im tired of that crap i just wanted to know if droping in a turbo motor was as easy as i thought... how hard would it be to convert to a turbo wireing harness!?? any ideas?

 

It's easier and cheaper just to sell your car and buy a TurboII.

Here's the price breakdown for used parts from salvage yards and private parties in $US if you can get a really good deal on things. New prices on these components are too prohibitive, so I'll stick with the used pricing.
$500 Working TII engine + IC & AFM (anything this cheap is going to need a rebuild soon)
$50 TII ECU, Wiring Harness, Various other parts
$400 TII Hood (Aluminum)
$50 Cheap Boost Gauge
=$1000 Total + A very long time to install the wiring harness

This is a better idea:
$2000 Working 87-88 TII car (once again, anything this cheap is going to need a rebuild soon, but it's good to compare to the $500 TII engine above)
-Whatever you can sell your car for
= ? Plus you get about $700 worth of used TII parts: heavy-duty transmission, differential, halfshafts, driveshaft, aerodynamics, and a lot less work.

Basically, if you can sell your car for more than $300 USD, you will come out ahead vs. the conversion, and it's a lot less work.

Both are easy if you do them improperly.

A standalone computer will save you the trouble of locating a TII ECU and wiring harness, but will cost you $800-4000 USD (a Haltech is about $1100 USD). However, the standalone computer will run the car MUCH better than the stock computer if someone knowledgeable tunes it, and you can use the standalone with any mods you like, or even use it on a different car later on. If you don't know what you are doing, a standalone will blow your engine.

The auto driveshaft thing is BS. If you are going to install a $450 used TII transmission, you may as well pay another $150 for a used TII rear sub-assembly which will better handle the power anyway.

 

this is the thing.. if i could drop in a engine fairly easy then i hope to do it... my engine is on its last legs.. ive invested about 12,000 into this car and love it to death so i hope to have it for awhile longer.. i want to try and find one in a junk yard and take the whole thing.. but that would be a little hard here there isnt that many.. does a j-spec come with a ecu?

 

oh sorry does it come with an ecu and everything else i need?

 

Sometimes, but not usually. You need to check with the importer.

You have $12000 CAN in your NA? What in the world did you spend it on?

 

suspention, wheels, tires, moto,r exhaust, preformance, few body mods, small stereo(nothing heavy)

/ ZZ Rated Racing Avon Tires / 5 Star Polished Aluminum Rims / Ported intake / Remove a/c , p/s , air pump / upgraded injectors / Fully adjustable Racing Koni struts / Racing Intrax Springs / 1.3" RB Sway Bar / Greddy Strut Bar / Momo Interior / Sweet System / Custom Single Exhaust / MSD Ignition / Blitz Filtercharger / Bonez Race Pipe / Painted Mirrors and Sides / S5 Tails / Major Weight Reduction / JDM Light Conversion / PIAA Fogs

 

OK, I see.

Were I in that situation, I would look for a TII with a blown engine (sells for $500-800 USD in my area). That way you can change out the entire rear end sub-assembly, and it also gets you the transmission, driveshaft, hood, brake booster line, etc.
Hints:
Before removing the TII drivetrain, mark the bolts and balancing tabs on the driveshaft so that you can re-install them in the same place, which will save you a lot of the re-balancing headache.
When removing the TII rear end sub-assembly, drop the whole thing at once rather than piece by piece. You can then just bolt it right up to your car along with your shocks and springs.

What to do about the engine, ECU, and wiring harness is a more difficult choice. It would probably be best to look around your area and see what is available and what it costs. It also depends on the shape of the TII donor car's engine and turbo. If the turbo is in good shape, it may be worth rebuilding the engine (approx $800 USD if you do it yourself).

 

i was going to get my engine rebuilt when this idea came to mind.. but what i am going to to is get it rebuilt and droped in for me by a fellow racer... might as well throw the tranny in as well and he hooks up the new harness then so im good to go!

 

just a quick question.. wouldnt a test pipe coming straight off the turbo out the side of the car make tons more power then a full exhaust?

 

i'm thinking the same as you just drop 13bt in and whatever else because in ontarion finding a s5 tII is almost impossible but even if i found one i love my car its in extremely good shape so i dont want to get rid of it ill probably do the swap once i get 7000$

 

Not necessarily, i had it explained to me one time that a car with just a downpipe makes less power than a car with a full exhaust (no cats). But of course i dont remember the specifics...

 

i would say it would make more power on a n/a which needs a bit of backpressure.. turbos less is better... test pipe coming off the side of the car ive seen only on race cars to keep flames off the cars behind i thought it would be a better and cheeper then getting a whole exhaust.. i think i might do this swap or buy a t2 and have a dedicated race car... ?? oh well suggestions!?

 

if you do this, and don't get a new trans/driveshaft/rearend, don't plan on upgrading the engine at all, or you can say goodbye to your NA drivetrain from the tranny back.

 

u need to upgrade your brakes to the TII ones
