Thats it for now, just a couple questions, what should i expect for power wise? Am i gonna need to get it tuned what should i set my timing to, Thanks, any help is greatly appreciated, thanks for looking at my post.

Are your SpeedPros dished for lower compression? What's the part #? They don't look like these, do they?



If they do, back to the drawing board!



Set your initial timing to 10* BTDC but you can play with it and see where it likes it. Disconnect the IAC and set idle to 700-800. With IAC connected the idle should hover around 1000. Now set your TPS to .94v.

You should be able to hit 300hp with no problem. I saw no mention of an AFPR or adjustable cam sprocket. You should have both. Then find a quality shop in your area, take it in and have it dyno tuned. Best couple hundred $$$ you ever spent!

that is the pistons i went with, factory d dished pistons. You say adjustable time gear? and what afpr would you reccomend?

evintho

Wow, those are the pistons everyone is trying to get but are now unavailable from Summit! They must have been sitting on your shelf for awhile.

This is the regulator you need.................
Kirban AFPR

and this is a good adjustable cam gear.........................
Racer Walsh adjustable cam gear

I run the one on the right.

Actually i ordered em about a week ago, they were on back order for like a week ina half, i should be getting them next week sometime, and thank you for the help i will be keep my post updated with the car. Thanks again

you say stock 5.5 rods. 5.5 is a "long rod" so are 5.7" the factory rod is a 5.2 just so you know. i hope you have 5.2s or else your piston will be making an unhappy hello with the roof of the combustion chamber.

also are you using a big main block or a small main block? i would also like to point out that the 1035 gasket is over rated. ive blown them on 24psi. i use the $10 na 2.3 paper felpro gasket. just spend 5 dollars on some spray paint, paint both sides of the gasket let it get really tacky(almost dry-very tar like) then put it on and torque the head as normal. i have had the same headgasket on my 2.3 as described for 16 of the 18 months ive owned it. its been mostly parked for the last 5months but ive had no issues with it.

Did you ever get your pistons?

93notch23tswap

Nope pistons did happen to be on national back order for atleast 8 months, i currently bought a stock 2.3t engine froma 87 thunderbird to get her rolling, I did order some CP pistons and some crower rods for my other engine, not sure what turbo i should run,

Slow84SVO

Talk to the local turbo builder near you. ill do some fast math for you based on your mods to give you an idea for what you want to run turbo wise. tell him the mods and that you planned on something around that area and see if he has any recommendations. will post up in a little.

Slow84SVO

Ok-based on your valvetrain work im assuming your VE will be an aproximate 90%.

with you wanting peak power at 6000rpm, i calculate aproximately 520cfm at 20psi and a 2.36PR.

so, at 3000rpm you have 18.22 lbs/min airflow at a pr of 2.36 at 6000 you have 36.44 lbs/min at a pr of 2.36. use these numbers for turbo map matching. that will give you a mean street turbo. if you want big big get a dry 50shot and put it in your exhaust manifold pointing right into the turbo. purge it then squeeze at wot around 2200rpms. it will spool fast. only need a second or two thou. it will raise exhaust temps FAST.

need anymore help, post up. someone can help.
