ha i have no go to turbo trash to talk .. but this low compression thing....... there is daring to be different but there is also to be dumb......... please prove me wrong make this low compression thing go faster than my t2.. well my t2 isnt stock anymore and even when it was just an FCD it was still fast .. at least make it perform well

 

Well it did have an FMIC that isn't really stock but it wasn't even standalone if that makes you feel any better

That is so messed up.

 

FCD won't make your car go any faster, FCD and a boost controller or FCD and an open exhaust however is a different story, and definitely not a stock TII those mods alone bring up the power tremendously be increasing the flow of the turbo.

You don't believe it Dub? Or you just think it is crazy? If you think it is crazy then I agree with you, and that is also the reason I am not running my car like that haha.

Ha ha, it was a surprise, yes, but keep in mind kahran has mods that are expensive, somewhat impractical and unusual: standalone, CUSTOM intake manifold, totally free flowing exhaust (have you seen / heard the video of his car?), S5 9,7 rotors and working VDI, and he dyno tested it on a dyno that doesn't read low like a Mustang dyno.

Good luck with ur project, and I hope it turns out being what you expect, and worth it in the end.

The real deal is total car performance........ I'd be interested in ur 1/4 mile times actually.

 

My car will only really be missing the super free flowing exhaust otherwise my mods are mostly similar to kahren's he has the advantage of Higher CR rotors but I have the advantage of porting. So only time is going to tell.

Break-in starting this week.

I am sooo glad you said that, I love my perfectly stock NA motor. in a few years only RX-7s left on the road will be the ones us "old Guys" have taken care of.

 

No you dont.

You said in the list of mods at the beginning of this thread that you're using the stock intake with the filter on the TB. That is in no way similar to Kahren's.

He has a custom manifold with straight runners coming off the block with the TB mounted on them, and I'm pretty sure he went through trial and error with tuning for the best length and size for the best power. That's a lot different than your setup.

Not trying to bring you down, but you seem to be expecting a lot from a ported n/a TII block with TII rotors, and well, best of luck I guess? Once break-in is done get it dyno'd and run the 1/4 if you want to prove us wrong, I'd be glad to see myself get proven wrong, it'd be interesting, I just doubt it.

 

And what exactly are you going to do about the intake anyway? We all know that the TII intake really isn't meant for an N/a due to it's runner sizes, you may have a nice flat torque curve, but it's going to follow a similar trend, no torque, still not much torque, a little more torque, and that little bit hanging around through the entire band.

 

I'm your huckleberry

 

How does that line match up with that quote? I just don't get it...

Holiday > *

 

Not that it matters, but FYI my NA had a haltech on it before kahren purchased one for his, you're not exactly breaking new ground here.

Good luck with the project, don't worry about everyone ******* it. You can theoretically run more timing with the lower compression rotors @ WOT, which you can easily exploit with the haltech.

 

Yeah, I have always been a fan of your posts pengarufoo and the parallels that can be drawn between your car and Kahren's are quite a few. Thanks for advice and the good luck, same to you and your own NA .

More to come.

Uhhh...a t2 with full exhuast/tid/fcd/fd pump at 10 pounds will put out 210-215rwhp all day long. The huge torque advantage the turbo will have isn't worth mentioning. I don't really see the point in this.

That dyno was from a board member who was pusing over 1 bar on the stock turbo. Basically the turbo could not flow that much air to redline, and bled boost like nearly all stock turbo's do. If it could have kept up with the airflow then the rwhp would be 300rwhp of higher.

 

just reading this thread has gotten me interested in n/a's again. I'm rooting for you Fritz! Show us what the n/a is made of.

 

There are other n/a's out there doing a lot. Kahren, pangarufoo, 88integraLS to name a few. People just don't seem to notice it I guess.

 

ok well let me buy the turbo or the intake manifold

 

I'm interested in seeing the outcome of this.

I'm one of those people who doesnt want a turbo

Post numbers!

 

Most people on this forum that are NA idolize those three persons, setups, and respectively the power that they make. Well, I know that I do anyway, they have some of the best of the best as far as parts go and each of those three are very innovative in their own ways with their cars. I don't see many other people mounting their alternators in different locations, or cutting off their sunroof and welding a solid roof on top. It's not everyday I see a post where someone has installed an LCD screen, to monitor their Haltech, with a program they they made themselves, to give graphic representations of different elements of the car's performance, on the fly.It seems that those 3 people you have mentioned get a great deal of notice, and respect, I believe that since my project is newer it is getting similar interest as well.

The one enormous difference between those people's setups, and my own are that they all run stock 6port motors whereas this will be a test of the 4 ports NA ability, at least for me. I know others have run 4p 13b NA's in the past but it's not often you hear about them in the 2nd gen section. Overall it will just be a couple of things that will be interesting to see for myself and I am guessing a few others.

While pengarufoo and Kahren (not sure about 88integraLS) have standalones on their NA's they are definitely in the minority, it is usually not considered a worthwhile mod if you're not simultaneously going turbo or doing some crazy porting like a full bridge. It just isn't seen as cost efficient by most people on the boards, and to a certain extent they are right, it is hard to justify the 2k or so to buy it, install it and tune it, when for that amount you could buy a nice suspension or equally nice exhaust and other costly parts.

And I think the last thing that is warranting attention, is that unlike those three, instead of starting NA and pushing that to it's limit, I started turbo and am "regressing" as some are putting it, going NA instead.

The truth is just like I have said, that we won't know until it is broken in, and tuned. Let the numbers be the proof. If this car makes less power than I want I will be somewhat disappointed but still content on attempting the project, but if it makes as much as I am hoping I think it would be quite nice.

Time will tell, we'll just have to wait. I will try to break in the motor as fast as possible however. I drive on average somewhere around 500+ miles a week, commuting(don't worry not steady rpm highway miles) and such. So we shouldn't have to wait long.

Believe me, 88IntegraLS is very cost effective with his mods He hit 14's with stock main cat and catback I believe at one point, it's pretty interesting. All he really has is a custom ported motor by him (and in my mind he really tested the limits of streetporting on n/a's), weight reduction, and now a header/high flow cat but i believe still stock catback. Oh yah and he does have an SAFC but no standalone.

I think it's great you're trying something new, more power to you. In fact I'm an N/A guy myself. This summer when I have more time to go to the dragstrip I'll be shooting for 14 flat possibly trying to break into 13's on a streetported (not even really very big), stock ECU, s4 n/a. I already know it's faster than my rx8 which runs a 14.5 when untuned, so only time will tell.

Good luck.

 

very interesting thread.. good luck fritz keep us updated with the project.
and as for being cost effective with mods, i think i win that... *cough* i just have no money and too many home brewed mod's... not too sure any of them are worth a damn, but it's all fun.

 

cost effective? 11's for $2500! woowoo!
