Well, it's finally happened everyone.

My car is actually running again, after two months down time!!

For those who don't know what i've been doing(probably everyone ) i've been turbo'ing my N/A '86.
It hasn't been starting for like the last week and now I finally got it running properly (not boosting YET.. ) it wouldn't start because of alot of stupid little things.. First I found it was SEVERELY flooded..(first time ever) finally got that fixed after a few days, then it had a massive vac. leak that took ages for me to find.. It turned out to be on my homemade EGR blockoff plate, got that 'fixed' (still leaks a tiny bit) today. Also fixed the oil leak coming from my oil line to the turbo, reason for this was my dodgy effort at tapping a hole in the top of a banjo bolt..

All I need now is to get my car to the exhaust place and decide on what i'm doing engine management wise.. (thinking LTX8 or E6K..)

 

man thats great.. tell us when you will be boosting.. theres quit some ppl that are doin this na-t thing and alot are workin so im thinkin about doin this too

 

If your going to be doing that kinda stuff, nothing should be sketchy, ie: egr blockoff, oil lines. if you're gonna do something, do it right the 1st time. On a more postive note, congrats, hope it works out for you. Ps: Haltech is nice! A lot easier than ppl say.

 

1Revvin7, Yes I've been trying my best not to make anything bodgy at all, the block off plate is perfect now, as is the oil the line.

I took it for a drive yesterday and fuel started leaking(not alot, but it was still fuel..) from where I removed the pulsation damper and installed just a 90deg. fitting in place of it. Got that fixed now too, just needed a new crush washer...

And yes I'm definatly leaning towards a Haltech.. My friends got a F9a on his 13BT S3 and even that is an awesome computer, so I can't wait to grab an E6K

Anyone think I might have some crossover point probs running 2x460cc and 2x1000cc injectors? (lets say on a _well tuned_ E6K for example..)

 

I'm one of those thinkin about the Na to turbo.. but is it worth the time, money, effort, and risk.. is it just better to spend that the time, effort and money on make'n the NA a fast NA, and keeping it a well working machine... i know everyone has different ideas.. i just don't know what to be thinkin yet?

 

I wouldn't personally do a turbo NA because it will never be a very high powered car to compete with the people you want to (z06s, supras, etc) due to the engine an drivetrain limitations.

 

I personally do like high comp. turbo engines, however, yes there are limitations on them. The only reason I have done this is because I got all the parts so far quite cheap and I don't mind spending shitloads of time working on my car...

Only thing that I wont be getting cheap is a haltech E6K . However, even if I was just getting a normal turbo engine in it I would be putting an aftermarket computer in it, so thats a bit of a non issue.

 

Its not THAT much of a difference anyway, remember

S4 non turbo = 9.4:1 compression
S5 Turbo = 9.0:1 compression

the turbo cars arent "low compression" compared to most turbo engines out there...

 

on a well tuned haltech, no way you will have problems.

 

I agree, thats why I went the extra mile

 

Ok awesome, thats what I wanted to hear!

 

another reason those s-afc are half assing it, its hard to get the transition to go smoothly with big secondary injectors, with standalones there are many ways to get it to be smooth.

 

Precisely why I didn't even consider a SAFC for my fueling requirements for this little project.

Anyone have any thoughts on different fuel pump setups?
I was thinking a FD fuel pump should be enough for quite a while (~300hp?), and I was just reading another thread about dual pumps, do you think I could run the N/A pump and an FD pump? or would it be better to run two identicle pumps in a dual situation?

 

nice job man. i also did turbo on my 90 gtu. ran great for a few weeks. but now wont fire. killing batteries tring to start. if it does start it spits and backfires and wont go above 2000 rpm. any suggestions.

 

Welcome to the 6-port turbo club! lol

 

I'm no expert but aren't 460's a little too small?
But hey..congrats..I am jealous!

 

I've been slowly going down this route myself. Im running a haltech e8 that im tuning myself. I say e8 all the way!

 

Run a supra fuel pump, and ditch the old fuel pump wiring while you're at it too.

But man, this is hilarious
