decided to turbo my 420a

[knight007]

Ok so i have decided to turbo my eclipse. This is what i got so far...

-supra side mount intercooler
-14b turbo
-boost gauge
-450 injectors
-downpipe

Im using my safc-2 to tune.

Now i just need the ic piping, bov, boost controller, and to tap my oil pan. Is there anything else that im missing i know i might need to upgrade the fuel a little more then just the injectors. I also had a few questions. Does anyone know were i can buy some ic piping to fit my car. I also was wondering how i could modify the wastegate, because i only will be boosting about 7lbs. I know theres a write up about modifying it with a spring but i was wondering if there was any other ways to modify it to open sooner?

Thanks ahead of time for the help.

You forgot one thing...To search!

The questions you asked have been answered 45,345,niner32 times..

14b isn't a bad turbo, however I would recommend going the Garrett T series route. Parts are more abundant, in turn much easier to find.

450 injects = no. You said you'll be keeping the boost at 7 psi, so the stockers will be fine.

Supra side mount isn't a bad idea, but a DSM sidemount would have done just fine.

For piping, a search on Ebay will yeild many results. There aren't any kits made for 420aT, due to all of the various positions the turbo can be mounted in, but a universal kit and a sawsall should be sufficient enough.

As for the rest of your list your missing a few things of course like oil lines, fuel pump, FMU and an oil pressure gauge is always a good idea...Check out Chris' write up for all the things you will need.

Again, try searching alittle around the 420a n/t-t conversion forums before posting a thread, you'll most likely find the answer you're looking for much quicker.

Yea ill search more and i had read chris's write up on it. Thanks hopefully itll be done by the end of this month.

missing link...what mani are you using?

missing link...

C'mon man, gotta pay more attention before posting that! Check out his year model(95). All 95s and some 96's don't require missing link due to OBD1 ECU/harness.

To the thread starter, like I just stated, you do not need missing link, it's a bleed valve that relieves pressure before the MAP sensor see's it so that ECU's on 96+ models don't send a higher voltage signal to the ECU causing it to cut fuel.

Thanks i was gonna ask about that because i saw it in chris's write up. As for the manifold i was thinking this one. Is this a good one? Do yall know were they sell them cheaper?

[talon749]

o wow im dumb haha i saw the 007 and thought 97 for some reason, as for the manifold there is a guy on ebay who makes theses for a living, real good quality, nice welds and a little cheaper then that one you were looking at....

Get your manifold from Mike Hart @ The Street Source. His products are great quality, and customer service is top notch if you ever have any issues. Well worth it in my and many others' opinions

yeah i have one of those manifolds...no problems yet. then again, i've only been boosted for a month and a half. he's a nice guy, just tell him what you want (flanges, where to place it...) and he'll work with ya

What do you guys think about using a FPR to compensate for the boost instead of a fuel controller? A heard a guy with a WRX said it worked fine.

 

[VelocitàPaola]

What are you talking about? We do use FPRs: either the Vortech FMU/S-FMU or otherwise. Fuel controllers (i.e. MS, EMS, etc.) are only necessary once you start boosting past about 15psi.

 

[98gsspy]

So what I was saying since he is only boosting 7psi why doesnt he just use a FPR instead of a fuel controller. The FPR will add more fuel as the boost increases. His stock fuel system would not do that.

 

[VelocitàPaola]

He will use a FPR; he'll have to. We all have to, that's just apart of turbo-ing a 420A.

Man, you make me soo happy stating that I don't need a missing link or FCD. Thats more money in my pocket... I should have my turbo conversion done by the frist week of next month. I'll post pics.

 

[DSMcrazy3]

No offense to you shadow, but if you were unaware of not needing FCD, you may be unaware of other things also. Be sure you've got everything together before you go installing everything. It could easily turn into a nightmare.

 

[XMasta19]

Amen to that....

Even if there is various positions the turbo can be mounted they still make many kits for it, they have one for sale on ebay right now for 150 with the intercooler and piping for the 420a, and they just sold one for 650 and they customize it anyway you want(the piping was powdercoated pretty neat ) and sbr will do any 420a intercooler kit you want for no more than 1100 dollars( maybe even cheaper they just said that was the most it would cost) and concept illusions sells the intercooler and piping for 900 dollars(best deal in my opinion, there intercooler can support up to 900 horses and it has a greddy type rs bov flange on it) just my little input though because im going on 5 months piecing my kit together and ive called alot of places, and with manifolds i went with the star one that Concept Illusions sells because he told that hes seen alot of manifolds prone to cracking and that you wont have to worry about it with this one

 

[knight007]

Ok what do you think about the ebay fpr.

http://cgi.ebay.com/ebaymotors/FUEL...005QQitemZ150007479803QQrdZ1QQsspagenameZWDVW

 

[420Adriver]

well the one i ordered had a screw fall out and i was fixing to tell you with those ones your gonna have to buy alot of hose and a few extra parts but i just saw that you have a 95 and your fpr is on the side of your fuel rail so that one should be good for you with little modification but if you do decide to buy a turbo kit alot of them already come with an fpr

Look at the prices. If you're willing to spend as much as it costs to piece your own turbo kit together, on just the IC and pipes go for it. I don't know of many people that are willing to do that though. The price of the one on Ebay is nice, but how big is the core? And I can almost guarentee you'll have to modify those pipes. To get SBR to make a kit for you it will take alot of precise measuring. I really don't think it's worth it. If you buy someones kit and it comes with everything, great. But when going the custom route I would just make your own pipes.

 

[knight007]

well im building my turbo kit because i think the kits are over priced. I haven't heard much bout the ebay fpr so i found a greddy one for 50 bucks so i just order that one.

 

[XMasta19]

You just ordered a greddy fpr....? If so, why? The only fuel management you'll need is a rising rate regulator, ie the vortech fmu.

it depends where you were looking for the parts at, ive never ordered those universal pipes and they seem pretty cheap i would just be leary if the couplers were real silicone and if those were good pipes(they might be) but i just got down ordering a few couplers from Concept Illusions and they were like 50 bucks each and with the different kits like that one i was saying being 150 and then there being one for 650, there is a big quality difference the 150 uses universal piping and the 650 uses good welding and backs up there product because its not wholesale from china, and your right but it shouldn't be to bad with the modifying should it? i mean just where the turbo sits you could mount the kind hook the ic pipes up to the tb and see how off the other ones are and then you would atleast have a good kit, but your right i never thought about pricing the ebay pipes ive always priced the pipes from car dealerships and they charge alot for there pipes and clamps and piping , on another note though there is that dsm wiseman who put a kit together for under 100 dollars with step by step instructions and it looks like he did a pretty good job as long as you now how to weld that seems like a pretty good option
edit: i didnt mean car dealership, i meant places like sbr and ci

 

[DSMcrazy3]

Well there are 3 different locations that the turbo flange can be mounted on the manifold. Left, center, or right. That will play a big part in if, or how well the pipes work. If mounted on the left, you'll have a hard time connecting the pipe to the turbo if the kit is made for a right side mounted flange. There are just so many variables, I don't think it's worth trying. I would rather buy the quality parts individually and route my own pipes.

If you have an exhaust shop near by they should be able to do the welding for you for around $50, granted you don't need more than 4 or 5 welds.

Lets handle anymore bickering through PM so this thread doesn't get too far off topic though, cool?


To the original poster, like Xmasta said you don't need to buy a fuel pressure regulator, you need a fuel pressure riser(such as Vortech FMU, again like Xmasta said). The FMU will work in conjunction with your stock FPR.

If you bought the Greddy FPR contact the seller and let them know you made a mistake and kindly ask for your money back. I've done this several times and each time the company/person has been more than kind to me as long as it hasn't been shipped out. If dealing with an individual you might have a more difficult time, if so, just re-sell it when you get it. Although you might not get as much as you paid.
