So I've been wondering this for a bit now, whether I'd want to do some sort of engine swap or convert to a turbo model. Anybody have any idea roughly how much it would cost and how much work is involved to do this?

 

Do a search a lot of people have conversions like this before. (Don't worry i've asked this question already

 

check the archives too!

Trust me its worth it to do the conversion, because you learn so much this is only my opinion, I have done it to quite a few cars, you need a jspec t2 motor $600to $900 -318 pressure sensor$20,- harness $150 or use a non turbo harness you have to do some minor adjustments to it like the twin scoll solinoid , you have to exstend the injector caps , you can use the non turbo maf, but before all that put a 3rd gen fuel pump or walboro, because I gaurantee you will pop the motor every one mods there car and forget it needs fuel,now that's only to get you going, I have a t2 rear t2 tranny,6puck,bnr turbo ,1.7chip,safc,npr front mount ,so I started small,now my cars a beast,I'm only giving my opinion that I learned so much , so we did a couple of my buddys cars now every one is happy,they no how to adjust there own cars and how to take car of them,but some people don't want to go though the hassle and power to them,all I'm saying its not as hard as you think,you have a lot of support from forum members,but we can't help you if you don't take care of your fuel

 

How much did it cost you to do the turbo swap?

 

I've been looking over the stuff, and it seems like a ton of work to swap it over. I might just end up putting an LT-1 in there.

 

It's not much work at all. Compared to the lt-1 swap. Its somewhat "easy" I guess for an engine swap. But search. Your answers will reveal themselves.

 

The LT-1 swap would be harder, wouldn't it? Having to have all kinds of **** fabbed up, modding the frame, it would get expensive. Just do the TII swap. I actually plan on doing a TII swap into my GXL, but I just gotta make some dough first.

 

ill be into my N/A turbo, $800. from stock to turboed, thats cheap. READ THE ARCHIVES.
people that thinks its expensive or hard to do

 

I've never undertood the point. If it were a convertible, I could see it, but I would think it would be far easier to sell the N/A and buy a turbo car. There is nothing to be gained other than you can say you did it.

So, what is it that any of you see as the benefit to this swap (vs. just buying a turbo car?)

 

Well, I would love to have a turbo car, but it just doesn't seem cost effective. To do the LT-1 swap and pay for everything, it would cost about 3500. It's gonna be too hard to find the turbo parts around here I have a feeling, not to mention I don't wanna have to buy a crap turbo engine and have to rebuild it. Actually, for the LT-1 swap, it's decently easy. Anyone have a price range on what it cost them for the turbo swap?

 

its cheap. and easy. you can do a 6port turbo if your motors good, or do a full swap for not very much money, and youll be able to wire up an aftermarket EMS and ... well its like getting a modded t2 off the bat. but if you have a gxl, id be more worried about getting rid of that damn AAS

i can tell you the best benefit of owning a na VIN with a turbo.. LOWER INSURANCE!!!!!!

 

Why is it like "getting a 'modded' t2"? Doesn't a GXL with a full T2 driveline weigh as much as a T2? As for cheaper insurance. That seems like a lot of expense to go through to get insurance that is a little (?) cheaper.

And what are your liabilities and coverages if you are involved in an accident with such a vehicle? Will the insurance company still cover you, or will they say "since your car is heavily modified, you are SOL?"

 

The motor in this car is mint, so that's why I really don't wanna trash it. Insurance will be lower, which will be good. So, how exactly do you go about doing this 6 port turbo?

 

S-E-A-R-C-H

This topic is covered extensively in the archives and somes up at least once a week...

 

Alright, I gathered together the differences between the GXL and Turbo II, and came up with this.

The turbo model came with a twill interior, turbo hood, a different drive shaft, a viscous limited slip differential, different rear axles, different rims and tires, body colored mirrors, optional anti-lock brakes (S4 model only), optional manual steering (S4 model only), black leather or cloth interior (S4 10th AE only), boost gauge, higher MPH gauge, different tach, transmission, engine, different power steering system (S5 model only).

The GXL had the AAS, a voltometer, and optional anti-lock brakes (87 and later models).

I believe those are all the differences between them.

 

it a lot ,but when you take the motor out,it all falls in place , youll scratch your head and say "why did i not do this before" , trust we will all help if you run into any issues ,there is no fabbing, it just all bolts up , make sure you 100% of your parts list.........

 

LT1 is less cost effective than an easy PLUG and PLAY turbo SWAP.

It is also easier to source 13BT motors than it is finding a TII in good shape. If you want to do the Lt1 go ahead but expect more work than a straight TII swap.

 

Alright, I just read through about the 6 port turbo, and that's a little too hack-job for me. I think I'd be better off just getting all the turbo stuff and doing it that way. There's no way you can do this turbo swap for cheap though. The engine alone would have to cost you 1000 bucks for anything close to decent, not to mention you're still gonna need the turbo II rear end, axles, drive shaft, transmission, ECU, wiring harness, and all that other crap. I could see the swap easily costing 2,000 bucks, which doesn't make it cost effective at all. I'd rather spend another 1,500 and have an engine and trans with 30k miles on them, and be running low 12's instead of low 14's on 2,000 bucks. I just don't see how it's cost effective at all.

 

Check http://1300cc.com and get the turbo kit. Only 1500 for the partial kit, supply your own fuel and intercooler, you're set .

 

This thread is dead. The only people who posted correct info said SEARCH! I find that funny realy. as jager said 1300cc.com "SonicRat" has pre CNC NA turbo kits to help out.

dennis blackstone I have check the meter on your post.........

 

Even with that kit, you're still gonna need a lot of parts. Seems like the only way to go is just to swap in all of the TII stuff. So my question now is, is there any parts that I can swap one at a time until I'm at a full TII swap? Like, could I get the differential and axles and put those in, then put in the drive shaft, and then put in the transmission and turbo engine together along with the ECU and wiring harness? Is there anything I'm missing there?

 

you can actually just put the motor in it with the NA tranny and rear end..........I wouldn't modify it past stock because the tranny willl break...look into buying a TII if you don't want to do it piece by piece.....

 

You have to do the whol drive line at one time. As well get the correct fly wheel to counter your motor it will be different.

Engin bay you can esaly modify your NA harness so no need to swap. You change ECU when you put motor in. you need to swap the PS from a TII and the motor and hood and do the wireing and your done realy. It is a bit of work but you realy need to do it all at once

 

if you don't want to use the NA tranny with the TII motor you can always get the tranny with the motor and use one of these for the rear end...but again, the NA diff and halfshaft may not hold up if you push more than 200hp
