I read up about boosting a itr so many times and i know its just do what you wanna do pretty much. its your car...i know id make great power. if i boost id do 12 psi on stock jdm itr swap. with one of the best tunner around here, very well known. just seeing what you guys would do if you had my car and why im stuck on a yeahhhh and a nawwww. any opinions?

MY CAR: 98 spec honda ITR REGISTERED
MOTOR: stock jdm itr swap.... parts that i already have
JG manifold attached to 70mm BDL TB
GOLDENEAGLE fuel rail mixed with XS fuel presure regulater 1000cc RC 255 wallbro hks cam gears on toda timing belt, "HYTECH" turbo manifold, Tial 46mm wastegate, Tial 50mm bov ,HKS front mount, HASSPORT MOUNTS, traction bars, ACT 6 puck sprung clutch pressure plate and flywheel
"MISSING" turbo custom charge pipes, down pipe, and dump tub
EXTERIOR: MUGEN hood, front bumper, side skirts, gen2 wing rolling on bronze 16 MF10 ADVANCE technology fronts and cusco basics rear FUNCTION7 LCA
INTERIOR :MUGEN FG360 and cluster, BRIDE LOWMAX GIAS KEVLAR, 7 point cusco cage MUGEN strut bars GUTTED
iv been NA and never been boosted iv already driven JRSC and a TURBOcharged set up

 

1. get anything psi right out of your head right now. means zero

2. get rid of that xs regulator, absolutely not needed

now on to business. if you turbo an R you absolutely MUST choose a goal

that means snappy and responsive or massive top end and drag racing. you can not have both

i'm going to go with snappy since that's really what fits the car. moderate hp and fast response. that of course means you'll look at one of two turbos

1. ballbearing gt28 from garrett
2. 5431e CEA from precision

the gt28 is the more expensive but it spools extremely quick and will allow the car to be used in autocross and track events. the 5431e is a billet wheel 50 trim that will make more whp but spools a bit slower, it's also a journal bearing. even guys who often love the NA itr will like a gt28 turbo version. couple that with a cast inline pro manifold and you'll have a snappy car.

you'll spend $4000-4500 to do this right and achieve 300 or so whp with a fast response and easy of adjustment. that basically means you can set the car from 250-350whp at the push of a button or change of a WG spring

if you want to drag race buy a 6262 and ramhorn manifold, huge injectors, tune and hold on, the bottom end will go north of 400whp but you'll blast off a bunch of 11sec passes on a stock engine

to turbo the car right you absolutely must design it all as one complementary package

 

thanks for the input. iv actually have been looking at the 5431 its a intry level turbo but a very very nice one.. i get so many people around me telling me not to boost and peeps saying just do it. soo much that im just keeping it low key now... stock r motor is nice even wit a built head and some stage3 cams but it still doesnt have a pull that i want and satified wit..

so i guess in your opinion is "why not boost" a jdm itr motor

 

use the XS FPR as a paper weight, get like an Aeromotive regulator. The Stage 3 cams might have a bit too much overlap and u may loose power, i would get a set if stock ITR cams they work good up to 800WHP, so you'll be fine....like the other guy said GT28R is a good option for up to 300WHP, above that its endless; ball bearing, billet wheels, twin scroll, extended tip, and so on, hp goals is important............ people that say don't boost, think NA is the greatest thing ever, till they drive something boosted hahaha............. good luck with the build

 

If you want a great ecu get a ProEFI 048. If you want the best for your ITR.

 

Personally I think any Honda with more than 350 whp is just useless on the street. I'd like the idea thrown out here the GT28, mmmmmmmaybe a GT30 but that's it.

 

you don't even need a regulator period. just buy the proper size injectors and tune accordingly

 

there are two 5431's the 5431b and 5431e, the 5431e is the superior of the two and uses a billet wheel. the 5431b isn't bad per se, it just surges north of 380whp or so. under that they have performed fine as far as i know.

the 5431b is being blown out for $550 shipped from a few places online, the 5431e is usually $670 shipped.

 

BOOSTED 01 R: my XS FPR is the one identical to the aeromotive.. its just thier mainly for looks lol ..IM not running my stage3 na cams TOP FUEL btw if i wanted tooo id run my JG turbo cams but nawww im gunna run stock head and block except for the bolt ons.

ROK STOK: that is a nnice EMS but i think im gunna run s300 or AEM just beacuse i have axcess to it right now ..


RACEBUM: yeah iv been lookin at the 5431E just another $100 for a better turbo



i actually found a b18c bare block im wondering if i should pic it up and just buy some 10.1 JE pistions and Rods and put it together right quick and put my built head on it and save my longblock on the side?? but i dont plan to do another HONDA just this one. So theres no point of saving it and i dont think i would sale it. FML PAPER(money) is a issue these days..

i should just boost my stock jdm itr motor that i have now huh?

 

It depends on what you want to do with your car. I was back and forth between turbo build and all motor for the longest time. I was dead set on turbo, had everything priced out and was ready to start buying. Then I realized how that completely takes away from what made this motor what it was because someone with a LS or GSR can do the same thing it just takes more PSI using the same turbo for them to achieve the same HP level. Then I thought about superchargers. Went back and forth with that for awhile. I was going to pick one up for a killer deal and drive down to LHT the next day for the intercooler and what not. I backed out and didn't pick it up. By the time you are done doing something proper and making it run without excess heat buildup, you are easily in the $4-5k range for what maybe 250whp supercharged. Which don't get me wrong it would be kick *** and fast but for the money I can build an all motor setup to do that. I am now sticking with all motor. I might not have the fastest thing in a straight line but its reliable and easy and shocking at the power out of such a small motor. Then again the sole purpose of my car is autox/road racing/dd.

 

a build is going to add thousands more onto this. if you used that 5431e or a gt28 you could set that stock R to 280-300whp and have it live for years and years provided you aren't driving around at 8500 everywhere and it's tuned correctly. if you feel you need more power you can do it down the road as that 5431e will support 400whp for the build you might do.

again, remember 205 50 15. you have to get all this power to the ground and if it's a street car there's a limit to traction

 

what is your power goal? and what do you plan to do with your car?

 

I sure wish I was at your elevation. Talking with Shawn Church and local tuners here, i'd probably never see over 200whp from a 1.8 where I live or I would've gone that route.

 

MY GOAL is 350-400hp rare car and parts for the shows but smashes on the streets, i hardly drive this car at all.. but when i do i beat the f*** out of it my car already handle like a champ in auto cross.. i dont care about being the fastest out there but i get pissed when some random kid talks **** about HONDA.. then shuts his mouth when i pull up hahaha

 

I agree with the previous guy who said over 350whp is useless on the street and the other guy who said pick to pick either responsiveness or top end power. I don't drag and I enjoy the road course, HPDE's and autoX so responsiveness is important to me.

Our cars have great top end, are lightweight and being FWD they are very efficient once they're rolling so you won't need that much to walk on most modded street cars. That's why most people will want to run you from a dig lol.

I had a friend building his teg with the goals of 500whp or something like that but after some street runs against EVO's, STI's and V8's in my 287whp teggie he was came around to just wanting more like 350 now.

A car's performance is measured in lap times, braking and cornering ability. Peak horsepower is an arbitrary number.

 

its true 300 is the lucky number i guess but paying so much just for 300hp is a kick in the ***. it'll be faster then most cars out der

the other 'quot" a gsr or a ls can make as much power just turn up the boost. so wit so much paper why not get another shell and boost that you know what im trying to say. is it worth boosting a R...?

 

Whether its worth it is up to you man. I love my R and driving an R is almost the pinnacle of Honda ownership imo. Making it perform better gets my thumbs up.

 

how can you say no to boost?

B(.)(.)STED ITR's Rock!!

 

How much HP is that? For me and boost I want an EG hatch with no luxuries, and start from scratch and have a fully built motor and making just stupid power. I'm talking like 800whp full out drag car. I'd get into way too much trouble having a 350whp daily.

 

I've been on the fence for a long time about boosting or going back n/a. I went from my R making 180/129 whp n/a to SC'd 258/175. Needless to say I was hooked! Not the fastest R but mine that I enjoyed.
Since the unfortunate death of my motor do to the tuner, I find it very difficult going back n/a and not just going the boost route again via turbo this time.
Been thinking of building a GSR block I have with just rods and pistons, then setting my R'd stock head on it. GT28/30 should yield me anywhere from 325-375 whp and that's plenty to keep me satisfied from a long time. I want to build something that's not a time bomb!
I really don't care much anymore about the 1320 and the time slip, I just want to have some fun with the car.
I did look into a mild n/a build with a 4.92 final drive in the tranny but I really don't believe that would satisfy me for long. Who knows only time will tell.

Opinions/suggestions?

 

600whp

 

Good Lord! No wonder the AP1 gave him a good run on the dig. But notice on the second pull from a roll it took of like a rocket. That is far more motor than I ever want on a FWD street car. I've run across some guys through the years that built their Hondas with gobs of power strictly for bragging rights. Kind of a "mines bigger that your" contest.
I want to build something where the turbo stays right in the efficiency range of the power I want. Where the boost and power band is more predictable.

 

I'm going to take a guess and say that you are 19 or younger. Since you care bout what yo peeps is saying! In that case keep your car slow so as to lessen the chance of killing someone with your mad vtack boosted r.

Honda tech, I am disappointed that you replied to this thread.

 

NO son im actually 25 grinding always . and i dont give a Fu*k if you "a" old man..my daily is a is300 ..slammed on RG1 stuntin on your bucket enough said.. its a question of people opinion to all but mainly to R OWNERS even though im hesitating to boost im pieceing my set up together way tooo fast that im doing it anyway.. go back to working your drive through... btw theres a reason why i own a r and you dont
