Boost on stock motor...need advice please.

Postby 88RS809 » March 23rd, 2013, 5:18 pm

I normally wouldn't go boost on a stock motor...but I have a turbo laying around; and I can't resist.

My 88 RS is bone stock, 190,xxx miles, been driving it for a month, no oil burning, no coolant loss, car feels great so I'm sure the compression isn't bad.

I don't know much about the ZC motors so I'll ask you the following questions,
1. The turbo I would use is a tiny stock eagle talon turbo, safe to run how many psi on a stock motor?
2. For the cheapest turbo build, what ecu set-up should I use? (What tuning software...base tunes available?)
3. What turbo manifold should I use? (What other cars have the same exhaust ports/compatible manifolds as ours?)

Thanks for the help guys, I really appreciate it!! :D

Do a compression test to make sure you have a healthy enough engine.
1. I wouldnt go past 6psi. Weak link are the rods.
2. You should convert to OBD1 and use a chipped OBD1 ecu. You can tune it with crome. I have a tune from my dohc zc on 6psi I can send you to get you going.
3. SOHC D series manifolds are close. I have a Greddy t25 manifold on mine. I may be selling it soon.... hint hint.

6psi sounds like more than enough for me, how do you like your 6psi set-up in terms of power and reliability?

Also that T25 is similar if not the same as the stock talon turbos correct?

I may be looking to purchase that manifold soon...hint hint haha!

And I'll compression test it when I change the spark plugs this week and see how it goes!

Its pretty fun. It is reliable now that i have replaced a couple original coolant lines. I am finding myself wanting more now that im used to it though. It is a nice sound hearing the turbo and blow off daily though.

My T25 is from a S13 silvia but a Talon turbo is also a T25 im pretty sure.

Hit me up if your interested in the manifold. I also will be selling the piping and probably boost controller and turbo timer.

G1 talons had the 14B and G2's had the T25. They should both have the same bolt pattern as well as the 16G. :geek:

Thanks that helps! I think mine is a T25, I'll have to recheck.

How's the MPG with the turbo setup...driving conservatively?

Dont let that kill your hopes. Mines tuned very rich for safety. I daily drive mine like that and I dont mind the terrible mileage. Its worth it to hear that turbo spool up when I get on the throttle.

On a side note I find that if im going on a long highway trip at an average of about 70mph, steady throttle with no stop lights, I get about 35mpg. Its the stopping and starting that kills it.
I have a 36 mile drive to work with oh say.... 8 stop lights and thats where I get 19mpg average, even though its all 55-60mph highway crusing between the lights.
Ive taken the car on 200 or so mile drives that were all highway crusing at 70 and thats where the 35mpg figure came from.

OBD1 swap which includes the ecu, wiring, distributor, and cap for the exhaust cam. Of course had the ecu chipped and dyno tuned once it was all finished. Higher flow fuel pump and larger injectors. Obviously the turbo, exhaust manifold, intercooler, and piping. Im sure im missing something here but thats basically the minimum.

Wideband Lamda perhaps?
With my Apexi Power Fc I log wideband and push down all the cells with critical knock value.
Either by adding fuel or making ignition less agressive. (Not the Teg though)

It would be awesome if you (Silentsnow) would make a new thread with a complete recepe for the turbo conversion, many of us would be most grateful :mrgreen:
