Hey guys....i've been debating this topic forever....and i'm still undecisive...granted that a T2 has alot more power and is obviously more responsive and faster....i'm having a trouble deciding wheather to save money and be carless for a while and get a turbo2 or carb. and modify my na....the whole problem is that a t2 runs for about 2500-3000 for a decent one around here and that if your lucky and actually find one....i have 1000 with me....i was thinking of carb. with some coil blasters on my na...or should i buy a 13b from the junkyard and port and rebuild that one.....i'm confused and looking for some help.... https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Your car came with EFI might as well keep it then having to rip out the pump and regulator and other stuff.Heres some insight I hope will help you a bit.275 rwhp NA

Depends if you want the feel of the turbo or not.. I have an n/a and it's cool, but never driven a TII. If I were you I would just keep saving some money and wait until you find a good TII. Good luck. :bigthumg:

RacerX: so your recomending a modified car./efi system with a port and mix and matching the motor itself??





Rx7Machine: i appreciate the advice...only thing that scares me tho is that i've been looking for a t2 for about 3-4 months and still haven't found one....so lets suppose i sell mine and get 2000 (highly unlikely) and add my 1000....then i would be stuck with no ride to work....no work = no money to play with....

i like na batter than a turbo, its a lot easier to drive.

Humm.. go with the n/a then.. he likes them too-->

I'm all about the highly modded N/As. Cheaper too, especially if you work on it yourself.

Yea.. but something about turbos.. https://www.nopistons.com/forums/pub...#>/biggrin.png ..is just great.

It's called boost, a highly addictive and a very costly drug!!!

Oh.. that's what it's called.. :smirk: I knew it started with a "B"..lol https://www.nopistons.com/forums/pub...#>/biggrin.png

With a hint of Zex mind you but yeah why not?You like the car don't you?

get a t2.I wish someone would have told me this a while ago, its not worth the $$$ to modify an n/a.Unless you plan on autocross. I would have saved so much money.

bridgeporto!

someone needs to do some serious intake experimenting with the NA 13B's, I suspect alot of the power gains in the renesis is in the intake.

Yeah, boost is definitely addictive. I miss it but at the same time I love the reliability/simplicity/and cost of my NA plus I'm only interested in Autocross now. My drag racing days are over...... not that T2's can't be great autocrossers though.

take a look at it the other way..im goin to tell you what i asked my mechanic when i first got into my new n/a.. he told me that while a tII can kick ass a modified n/a woudl be fast aswell and more dependable......not to mention sometimes turbos can go out real quik...neighbor hates rx-7s cause his tubo blew the same week he bought it new..and it was a gen 2...but i dont know **** myself..just telling you what ive heard...

:bigthumg:

Speed is an addiction, you just want more and more, you can't get it fast enough while being n/a and there is a limit which you can reach quickly, that still isn't anywhere near enough. Well atleast this has been my experience.

i think the na upper intake is a lot better than the t2's



mike

what about s4 vs s5, both na?

oh i think the s5 upper is better than the s4, but i dont have hard numbers



mike

I think for turbo applications the RE intake is the best upper intake I have seen for flow design stock.

yah that and the fd are both good



mike

darrell, here are the specs on that 275 hp fella ....



Phillips B-32, 105 octane

Engine 13b bridge port, 75' 13b rotor housings, '89 rotors & shaft, lightened & balanced, hardened stationary gears, carbon apex seals and oil baffle plate.

Intake Weber 48 IDA

Exhaust Custom stainless steel header, 24" primary, 3" main, DynoMax 3" in/out

Cooling 84-85 SE oil cooler, be cool radiator, Mezier electric 35GPM water pump (remotely mounted)

Ignition Direct Fire, Jacobs Rotary Pack..



the power i would say is from the bridge port, 105 octane, the balancing & electric water pump...(remember what i told u about those )

...he is very impressive though ..

Theres a link to that page thru the link to the thread in the engine and porting forum.Then theres Rotarymans ultimate NA 310hp engine idea.Nice maxed out NA with a hint of NOS. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif BTW nice location you have listed there.I love it when people brag they have Vtec and think they're fast enough to win a race.The sorry looks when they lose to someone else. :bigthumg:

I don't care much for "speed".. even though it did feel cool hitting 140.. what I really like is how "quick" the car is.. from point to point. That's just me though.

i'm not quite sure what to make of that statement there MR Guru...



https://www.nopistons.com/forums/pub...IR#>/dunno.gif

I don't care about going 180mph, just whipping the head back, thats what its all about https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

The price of those mods would be pretty hefty. I have seen carbon apex seals alone go for 1800 USD.

you also have to remember, bridge ports dont exactly last too long, and they arent very ideal for a street car .. unless you like the 2k+ fluctuating idle. If you drive the car everyday, its a bad idea, i think anyways. You might want to.

While its certainly possible to make an n/a fast, by the time you did, you'd have spent more than if you just went out and bought a turbo.



If you have a serious need for speed, buy a Turbo II.



If you want a fun, economical daily driver, buy an n/a.



And while there are exceptions to this rule, remember: The faster your car is, the more time its going to spend sitting in the shop getting fixed.



And most definitely: As the speed of your car increases, so does the rate at which money flies out of your wallet. There are no exceptions to this rule!

You got that right!

I'll go with N/A modded running a happy mid 12



And i'm NOT a drag racer either. It could be an extreamly balanced sports car still getting 15mpg

"I love N.A."

you sia d you need the ride to get you to work... so if you need reliability, you better go with the na. cuz turbo 2's as much fun and a fast as they can be are not as reliable.

I took a T2 with a downpipe

on stock ports with the 88 manifold



Bridgeports can have a nice 1000-1200 rpm idle with a tuned EFI system
