Right now I am in a serious toss up b/t purchasing an AP1 and AP2. I know there are a lot of threads in here to help me with my problem but what it really boils down to me is something rather simple. If I get an AP1, I can get the 2.2 stroker kit from Spoon and raise compression up to 11.8 which should give me about 260hp and 188 torque based on Road and Track's review. I'll make max power sooner at 8500 rpm but I'll have a lot more torque available throughout the powerband kinda like the AP2 except more power. My question is the following...given that the AP2 already has a torque increase over the AP1 but not as strong as the stroked AP1, would it make sense to use the stroker parts for the AP1 on the AP2?? From my understanding, they are the same block and so all that would be replaced are the parts from the stroker kit...sort of like restroking it by swapping out pistons, piston rings, crankshaft, etc.?? What do you guys think...think it will work??

 

i'd like to know too

 

Come on guys...I've seen that 44 people have already seen this post as of now...can you guys please respond with some kind of answer...??

 

You probably don't have more answers because this is a very technical question.

 

I think folks are trying to avoid the usual mindless flame war.

The AP2 is a stroked AP1 USA model. I have real doubts that you can run pump gas at that compression, but that depends on where you live.

It doesn't make any sense to me to tear into a good motor for what will in reality be a minor torque increase. You would be far better off to just go to turbo/super and get some real power.

 

Or if you don't want to go that route, get InLinePro's 2.5 liter or 2.7 liter stroker and ITBs... anyone know what the news is on the cams that have been in the works?

 

...but before I worried about that, I would just get an S2000... If you are going to rip apart the engine and rebuild it (stroke kit) I would just go for the cheaper and more raw AP1 (if you were going to track it) ...it would give you more money to play with (NA is a lot more expensive than FI)

 

It would be a costly and difficult challenge to get a 2.2 to make 260 Hp and 188 lbs/tq. I'm skeptical on those numbers.. MAYBE a 2.4L stroked.

11:1 to 11.8:1 would do very little to HP/TQ #'s and you can easily run pump gas, I even think 91 would be ok.

Here's what it boils down to, street driven application or strictly track?

If you're looking for N/A performance, here's a few options.

ITB, AP1 intake Cam or custom on stroked AP2, AEM ECU.

In a nutshell if you have a shorter stroke, you can rev higher and make top end HP. If you lengthen the stroke, you will lose that HP but gain torque. To get both worlds you will need to do some serious work, ie stroked, sleeves, pistons, crank, cams, Ti head work, ECU and the list goes on.

 

Dont bother with Spoon unless you would like to overpay for JDM bling. I think you should buy whichever one you like the best and then once you have it start talking to some of the sponsers on s2ki such as ya at inline...

To answer your question, NO you cant just swap in the spoon parts. You can build an Ap2 up with Spoon parts.

 

Well, I want to have something thats balanced that I can definitely live with as a DD and at the same time, something that won't put me to shame if I peak my head at a track...kinda like Spoon's approach, make a track monster but defintely liveable with every day...

I know I like the AP2...I've driven one and I'm in love all though many claim the AP1 is way better...what I'm thinking is that since its essentially the same block and heads with just slightly different internals...and given that the AP2's got better displacement, it should handle and respond to power upgrades better than an F20C...rite??

I didn't think that N/A would be more expensive than FI... I mean, in the long run I'll probably have to spend more $$ on maintenance and such whereas NA could last me longer...rite??
