As I have stated in a previous post I am going to start building a 1.8T for fun. I will be posting all questions in this thread along with all of my pics, etc.. of the project.

To start it off I just bought a turbo and intercooler off of a 1990 GS-T for 100 dollars gotta love ebay :D should be here in about 2-3 days. will post pics on arrival.

1.8T... sounds like a VW!!!

Good luck with the build.

lol yea i thought that same thing when I typed it haha. and thanks ill need all the luck I can get haha my biggest prob is gonna be finding a 4G32B (84-87 colt/mirage) exhaust manifold. my buddie's junk yard didnt have one when I asked so its just a waiting game :/

Ok so I figured I should list everything I am going to be needing in case anyone might have something for sale or are curious what is needed( items with a * beside it have already been obtained)

1) Custom tubular exhaust manifold

* 2) Boost Gauge (mechanical)

* 3) MBC (manual Boost Controller)

* 4) AFC Neo (or similar fuel managment unit)

* 5) 450cc injectors

* 6)Turbo (T3/T4 or MHI 14B or MHI 16G)

* 7) intercooler (SM or FM, either will work, I used the stock SM from a 1g GS-T)

* 8) Stock 1g BOV (or any other Reccirculating BOV. It MUST be recirculating, a Vented BOV messes up the AFR too much in a 1.8 and will drown the motor between shifts.

9) Custom Intercooler Piping (upper and lower, although it IS possible to get an after market UIP to fit with a few turbo couplings it is much easier just to have one made.

10) Custom Downpipe

11) Braided steel oil lines and a T-fitting

12) custom intake piping

13) Bigger Camshafts (not necessary but thought I would throw it int here anyway for the hell of it.

14) Rebuild kit

15) Oil cooler

16) 2x Felpro head gaskets



Well, That about covers it. The list will slowly be marked off, however, like stated before I only can spend about 200 a month on the car since I am still going to school and have alot of bills to pay for my age and I also have to pay for school (and i pay in full I dont use loans)

You may want to get in touch with some Aussies. I think that car is pretty common down under.

GTO Scotty would be of some help to you.

Also I have a question to ask:

as far as the Intake piping goes do you think I should just use a pipe made for the 1g since I am using the turbo from the 1g anyway? I don't see why this wouldn't work, but thought I would ask anyway.

Is GTO scotty on this board or another section?

Yeah your gonna have to PM him as he doesn't check the eclipse section.

He also just moved and works for ESPN so he's a busy guy. So you may have to wait a bit for a response.

Aight, thanx bro.

also anyone here used the SBR MBC? if so any good?

Ok just an update:

I went to advanced auto looking for 390cc injectors... they wanted $245... EACH!! i was like are u fucking serious!?!? looks like its back to the dsm graveyard :x

yes and yes. We've used it on the SRT we had with a 50trim baby kahuna varying from 22-35psi. If it can control that frankenstein of a surge prone turbo then it is pretty good in my eyes.

great cause 45 for a MBC is pretty **** cheap if u ask me :D

jump on Ebay and find some used 450's from a DSM. They are all over the place for $50 for 4. Or if you have time to wait Im probably going to be changing out my stockers in the next 2 weeks or so and I will send them out to you for the cost of shipping

You arent going to mess with the internals at all? i dont know a whole lot about the 1.8L engines; how much boost can the stock in internals take?

yeah, you will see why it is so cheap once you get it. It isn't constructed poorly and works well but its a VERY simple design. 1 inlet, 1 outlet and 1 hex head screw that adjusts it. it only takes about 1/16th of a turn to adjust it about 2psi. very sensitive

no I dont want to mess with the internals because the way I see it those things were engineered to a point and I dont know of any name brands who make quality performance internals for the 1.8

as for boost, there are alot of variables that can determin what you can run.

with the stuff I listed you can safely run around 11 psi with a 9:1 AFR (with one head gasket) if you use 2 head gaskets u can run more tho I am not sure of the numbers for it.

also keep in mind these numbers are with a smaller sized turbo.

I am doing this more as a learning experience than looking for a race car lol. once its said and done will only be pushing around 230 hp

ok well you think 450cc will be a bit too much? if not ill be all over that. I dont get paid again until Friday so I cant pick anything else up until then anyway but yea, if you think the 450's will work then sure Ill be happy to take 'em off your hands :D

Ok so my turbo came in and Im rather happy with what I found. I tested it for shafte play and there is absolutely none! :D only 3 things I noticed about my buy:

1) There is a hairline heat crack in the housing. I dont think it will cause much problem since I will be running at realtivly low boost. what do y'all think?

2) I really dont know what it is (looks like something used to stabalize the turbo, like hold it in place) but its a metal rodd coming off of the housing and its bent irregularly (check the pics)

3) as you can see in the pics, the end of one of the tubes coming from the intercooler is dented.

4) same thing as above but with the tube running to the BoV (also seen in pics)

Sry for the shitty quality I took the pics on a shittyu camera phone... and yea I dunno if you can see the heat crack or not from the photo but its a small hairline one.

Are you still looking for a BOV or is the one you just got gonna be ok?

Oh and that intercooler is probably going to leak at that connection I would try and bend it out.
