So I had a motor built by this forums most notorious conartist. I recently discovered I'm leaking oil from the pump he was supposed to fix when he completely rebuilt my motor. Now I have a god knows how reliable 2.3 liter motor with headwork done to who knows what extent. I've finally decided to just cut my losses and do another entire built myself. HERE's my delema. SOOOOOOOO many people have their own opinions about all this stuff. I really like AMS's parts/work. I want to stick with a stroker motor. I will be racing this car at least once a week at the strip. I plan on using 93 pump ONLY for now(once i feel i've pulled every possible horse out of pump gas then i'll do alky or race gas. The car will be driven daily. I do not need to cart granny around so I'm fine with a rough ride. Turbo spool vs hp is my biggest concern. I have no idea what to get. WAS set on doing a 35r not i dont know. I'd love for AMS to give me some REALISTIC spool specs for different kits with their 2.3 liter stroker kit. AMS and anyone else with good input please point me in the right direction.

on pump gas with our 2.3 stroker motor on the street you should see 20 psi by about 3700 RPM. This has been proven many times over

From what I've read. If you get their 2.3 stroker with a 35r kit, supporting mods and a good tune you will be fine. Depending on your state laws you can run an aem ems (if they dont have to hook up to your OBD for inspections) which is the best standalone bc you can fine tune so many different peramiters.(sp) i take it you will be sending them your motor that had your work done on? if thats the case its really a shot in the dark. you dont know what this guy did to your block and head and really wont know until u rip it out and have AMS tear it down and see whats up with it. You might be better off having AMS building you a motor from scratch. It will def cost a pretty penny but you are then 100% sure that its brand new and there are no doubts. I mean you can send them your motor...do you have another car to get around in while they build it? the next question is do u have the $ to fund this. I wish you the best and def. keep us posted!

 

I'll definately be buying an AMS shortblock with a new core. I cant deal with the headaches of this car now. I have an AEM EMS now and dont need to worry about getting stickers . Eric or Martin...or anyone on th AMS crew that could answer me this...When would the turnaround be for ordering a 2.3 liter shortblock with a new core? Also what horsepower range would I be looking at with a 35r(with all supporting mods) on pump gas. This is with some headwork too(ported, 5 angle valve job, 1mm oversize valves, revolvers, springs/retainers).

btw, what does oringing the block do? would you not need a gasket if you do?

 

turnaround time right now is about 3-4 weeks, we are pretty backed up with motor builds.

on pump gas you can expect about 420 to the wheels. I would hightly recomend runnign some kind of water injection at the very least to really wake that car up.

ok. How about whp on a 3076. And Why would you do copper Orings on the block?

 

by O-ringing the block you just create a better seal between the head and the block

3076R's usually peak out at about 520 ish for hp, maybe a little more.

Do the Orings eliminate the need for a gasket?

 

Here you go: https://www.evolutionm.net/forums/sh...d.php?t=195066

Your actual spoolup will be affected by quite a few variables:
- cams: if HKS 264s are the base, then 272s = +100rpm, and 280s = +200rpm
- cam timing can affect your spool by as much as +/- 200rpm
- Ported head (good port) = +/- ??? rpm
- Ported head (poor port) = +/- ??? rpm
- Better Intake manifold = +/- ??? rpm

As seen in Smoggy's dyno chart, a well built 2.3 will have a similar power curve to a stock turbo car (i.e. you're making the same power during spoolup, but the 2.3L 35r keeps on making more power after the stocker hits its peak). I'd expect a 3076 to spool earlier and make slightly less power on pump, though it shouldn't be too far off the 35r on pump gas.

The O-ring does not eliminate the need for a gasket, it aids it in the sealing process.

Is this something commonly done?
