Well I didn't make a "Build" thread, so this is the next best thing. Here it is in turbocharged glory! I think I should name it.. Black Betty ;D








Last two are low and high boost settings, 8 and 12 PSI respectively. Specs are as follows:
'97 1.8L
Wiseco Pistons
M-tuned rods
Ported and polished head
FM dual flow fuel rail
RC 550CC injectors
Garrett T25 "SR-20" turbo
Megasquirt Piggyback
CX intercooler
ebay clutch
fidanZa flywheel
Turbo XS BOV
Turbo XS dual stage boost controller
Tial 38mm external wastegate
tokico shocks and springs
FM sways
hard dog roll bar
BBS pininfarina 15x7
cooper Zenon ZPT tires

 

nice clean setup. what manifold did you use?

 

Thanks man! I can't remember if it's the old BEGI type or the old FM type.. It's one of those lol

 

You done good Adam. Yessireee.

 

needs more turbo

 

old fm = old begi

 

Plans for more boost? Seems like with your rods, pistons, and injectors, you'd be good for more powa!

 

+1 for moar boost!!!

 

That poor little turbo has no more boost in it. lol.

Lot of different options if you need to upgrade...but that should be plenty to beat on for a while.

 

It's got a couple more pounds left in it.

 

Oh yea I'm still in shock.. it's a LOT faster than my dad's 911, plus it handles better too... I doubt we will go to a bigger turbo before a new diff though, we don't need that exploding a hundred miles from the house at an auto-x.

 

sure it can boost up to 22psi...but it still cant output more than 25 lb/min (230hp)

 

Great build! Fantastic looking car, and good power. Right about where I would like to be, in the ~225whp range. Those turn signals are pretty neat, arrows. Never seen that before.

 

Well shank ya. I'm kinda on the fence about the signals, I have never seen anybody else do anything even similar before, I might just leave it..

 

those finnies are ******* awesome.

 

With that mildly built motor, you need a bigger turbo... 2554r at a minimum. It doesn't look like you're after "big" power, but I'd still aim for 2560. You'll sacrifice nothing for spool over the current journal bearing turbo, and the greater efficiency will mean less heat management issues (ie, able to run more timing).

Run the EBC ground line out of the ECU through a simple on/off toggle switch on the dash. You won't hurt the dif running 7-8psi wastegate on a 2560 if you don't hammer the clutch off the line, and just wait until about halfway through second to toggle the hi-boost.

In a straight line roll-on, the 6" dif will do just fine at moderate power levels... it's wheel-hop off the line that kills them.

 

Yes you need a bigger turbo. Post your spark table, I want to know where those humps in torque stem from. I bet your spark table isn't smooth.


That's really good power for a GT2554. Don't forget that a DD reads 10-12% lower than a dynojet (in my experience). You should really slap a GT2560 on there.

 

At this point enough money has been thrown at the car, and I am satisfied with current power levels. Eventually, I would like to sell the motor and go with an LS1 swap, maybe even with a supercharger.. I will try and pull the spark table, thats kinda hard given I only have access to a windows computer like once a week..

 

Those were the ones I had for sale like two years ago. lol.


Guys. He has an SR20 .86 T25, not a GT2554r. Read first post. That power is pretty impressive from that turbo.


The car is a 97 right? Means you have the 7" and you car SHOULD have an LSD if I remember it correctly. I wouldn't worry about the rear end at all.

 

Is that the one more comparable to the 2560 from the later SR20's?
