Default Calling All JDM STi Swaps...

I'm trying to get a roll call going. JDM 2.0 STi swaps only please... Post up with a picture of your car and a brief blurb about your swap. My friend raised a good question regarding the rarity of these cars, and I'd like to try to tally up the NASIOC'ers with 207's!

ok, for those who put in the 207, do you wish you did the 257? or is the extra rpms worth it?

Well it depends. There is a whole lot more the the 207 than just the rpm's bro.
But, to answer your question, would the extra torque be worth it with a 2.5? Depends on the person and driving style. I prefer the feel of a JDM 2.0. Some prefer grunt and no lag. Me I just drop 4 gears on the JDM 6mt and nail it. I love spinnin and shifting. Like a race car. Those who hate shifting may want the 2.5. I am not a fan of Viper power delivery. Personally I would like 8 gears and 9K rpm. Can't get enough shifting for me. I like the involvment. The 2.5 is more like a meat cleaver. The JDM is more lika a scalpel. Depends on ther person. I am more of a road racing guy others are more of a drag racing guy. Generally drag guys like the 257 circut racers likek hte 207. Generally that is.... One is not better although as far as being used but the 207 is a far better engine. Does not make it right for everyone though.

I have a 2.5 short block in the garage in the crate. If my 207 bottom goes I'll try the 2.5 for a while. I am in no hurry to swap it. (Mainly because it was new and cheap I have it.) I do not wish I had done that first. I like the 207 ver8.

I personally know several who have had both. Kind of goes like this. They hate the 2.5 but like the torque. They like the power you can get on pump fuel. Some will go back to the 207 and some won't. There is one common item. They all wish they never broke the 207 in the first place. Drag guys are staying 257, road course guys want the 207.

For what it is worth, the 207 with the 5mt and R160 was lame. Almost got fed up and sold the car. It just never met the hype. It was not until I switched to the R180 and 6mt that the car TRULY felt different. Now I get it. The is the whole JDM Driveline that make it superb the engine is a component from part of a matched set.

Personally, knowing what I know now, I would have probably kept the US motor with an 18G and put in the JDM 6mt and whole rear sub frame. I would have done the motor last. That would be a really fun car by the way.

Hope that helps.

I agree with ebeck in that the tranny is the best part of the swap. If I had to choose between the motor and the tranny I would definately take the tranny first. It is the best overall transmission I've ever driven... only the S2000 and other Honda trannys feel smoother, but none are as confidence inspiring as the sti 6-speed. I do what I want, when I want it, without feeling like I'm driving a truck (read: mustang/vette).

IMO my car is better than a USDM sti in every respect. If I had to do it over, I would have gotten a USDM sti for the peace of mind, but now that I'm here, I wouldn't trade my car in for an sti... although I've had numerous opportunities.

In the future I hope to have some kind of rotated turbo thanks to the inepensiveness of the Perrin GT kit. A new steering rack to get rid of 3 turns lock to lock and I'll have the perfect car.

This says it all. I like precision, not brute force.

For the record, the GT35R and Greddy T67 kits were designed around the EJ207 simply because the higher RPMs is when the motor comes alive. If the *stock* 257 block could rev that high, there would be more 600+whp 257s out there. It has been proven that a stock 207 can deliver 500+whp on pump gas with a GT35R kit.

Question is how much power can the 207 handle reliably on pump gas? I know that the 207 has forged internals but how much can it handle with out having to constantly worry? 450hp?

I'm gonna go out on a limb and say 400whp is upper limit I would live at for a daily driver. I would switch to another map and race gas for a day at the strip/track.

If all you do is drag racing, then I can see why you want a 750 hp machine. But I have an EJ20K in a GC body that pushes around 300 hp. That's plenty of power for daily driving, climbing canyons, and -crossing of anykind.

Lachlan is correct. No motor is going to live long making 400+whp as a daily driver, and being driven hard. For racing sure 800whp why not but then they replace the motor every 3K miles or what not. For 450whp daily driver you need less hp per litre and hence a longer life due to reduced stresses. Look to the Vette for that kind of power.

400hp at the crank the JDM can do all day for years if you tune correctly and take care of it like your life depended on it.

For the record I have never seen a JDM motor make more than 350whp or so on 91 octane.

I'd like to keep this thread as a roll call... if you have questions regarding putting together a swap, reasons for a swap, etc. please check out Capt Crunch's thread: "To those that want to make stage 4 power or more..." (http://forums.nasioc.com/forums/showthread.php?t=670037)

Thanks for the replies guys, keep them coming. Who else is rocking a JDM STi motor?

Well, I have seen my own car lay down 330whp on 92 and a Momentum 40T/pinks on 21psi. There is alot of room for our motors to breathe, and while I think that 400whp is excessive to be daily driven, I just threw out a number that I have heard of run daily on one with no probs... yet.

Not that its a smart thing... but I have overboosted my motor several times to above 30psi (trying to set my frikkin Greddy Profec B spec II ) and it is still as fresh as ever.

As much as i would love to have a proper matching 6sp to complete the swap, I partially agree with the lameness of the 5sp and r160.

I've pulled several stock USDM sti's off a launch with the 5mt, advantage due to the taller 1st gear in the 5mt and and extra shift for the 6mt, but for the most part i don't press my luck with strength my 5mt. 2nd through 4th pulls are pretty good IMO for a gearbox designed for US market concerned about mpg for overall fleet of vehicles,etc..
however my biggest gripe is the front and rear diffs of the 5mt/r160.
when getting agressive with it, it feels double peglegged while grabbing for traction in the corners.

hopefully i get my 6mt in before one of these cellphone talking soccer moms smack me up

sorry bout the tranny talk..keep the 207s coming
