What ecu, fuel pump, & injectors should he use??
 
I currently have a friend who is just getting into cars. He has a 87 GxL n/a & made it turbo using a turbo from a t2 with a fmic, HKS Intake kit, HKS super sequential blow-off valve. He is doing 13.8's @ 107mph at the track on just 6psi. He is currently planning on upgrading the turbo & getting a Garrett T3/T04E, running on 12psi, using a Weapon R fuel pressure regulator, & installing a Nos kit but not going past a 100 shot of it. So the question is, what type of injectors should he get?? Should he get a Nippondenso or Walbro fuel pump?? And could he control this whole system with a s-afc II. Please reply quickly cause we are trying to get this project started A.S.A.P.

He should get a rebuild kit

StinkyTurbo 01-06-05 12:08 AM

Yea he is, but he just wants to know what else to get. He also has a Turbo Xs manual boost controller & a 3 inch downpipe with no cat with an Apexi 3inch exhaust.

Oh ya, after he does that, He could get the Walboro pump, the S-AFCII, XS FPR, and get 720cc secs and clean of get new prims. Why not trach the manual boost controller for a AVC-R, its a lot more but boost is 99% in check.

StinkyTurbo 01-06-05 06:20 PM

Damn. None of you guys can help??

jg1bad10th 01-06-05 08:28 PM

I do agree that you should get a TII engine.the engine is better at handling the boost than the n/a.

the apexi can only control injectors up to 720.maybe a little higher but no much.so if you want more boost you'll have to go with a stand alone.

you'll need to first upgrade the fuel pump.rewire it.and deside to get 720's with apexi or stand alone with 1600's.all really depends on what kind of power your looking for.

Wrong, if you don't know what your on about don't talk about it.

The N/A engine can handle boost without a problem.
The stock ECU however is lesss than ideal.

Get a standalone fuel/ign computer first before _ANYTHING_ else.

StinkyTurbo 01-06-05 09:16 PM

Ok. This is stinky277's friend. Would it be ok if I just take the 550 cc injectors from a t2 for primaries & use 720 cc secondaries using a s-afc II with a nippondenso fuel pump, because seriously, I can't afford a standalone like a haltech

White_FC 01-06-05 09:23 PM

If I can afford a stand alone anyone can.. seriously.

Just look for a second hand microtech or something.
It doesn't have to be brand new at all.

Hell I'm running an old microtech digi 1 pro fuel/ign and it's perfect.
Was just about free aswell.

StinkyTurbo 01-06-05 09:31 PM

The reason I keep suggesting a s-afc II because some dude that owns an s2000 is selling me one for a $100. So I wanna know if I should jump on that deal & use a piggyback system instead waisting $1,200 extra on a brand new standalone or just waiting a week or three for another deal to come up on a standalone.

White_FC 01-06-05 09:35 PM

I would not recomend a SAFC for a far from stock application like yours.
Some other people on here have done it sucessfully and will recomend it.

Also it is not a waste of money buying a standalone now if your going to be upgrading your turbo soon.

StinkyTurbo 01-06-05 09:53 PM

You have a point White Fc & I've made my decision to just save my money up & get a Haltech. But still, can't I just do the application for now with s-afc II then when money comes together I just go ahead & get the Haltech.

what?

first off.if the guy is looking to make big #. your full of shit.I didn't say he couldn't use the n/a .but the turbo engine has LOWER compression rotors which will allow more boost. which =more h.p.

like I said. it all just depends on what he is trying to do.this is why so few people post is because of people like you wanting to start smarting off on some b.s.

I have spoke to alot of people on this forum and I'm also running a apexi with 720's with no problems. with my t04.

I'd say buy the apexi and go with the 720's.if your not happy with it. you can always get your money back selling the apexi. then go with a stand alone.

StinkyTurbo 01-06-05 10:26 PM

Anyone else's opinion. Also whats the biggest injectors you can use with s-afc II.

How am I full of shit?

I didn't say you said he couldn't use the N/A block?!
I said that the N/A block can handle boost just fine, more than most turbo's would be able to throw at it.
You seemed to think this is not true. Sorry.. It is.
I would NOT use the stock ECU though, it might not be able to run the same timing as stock, might need more retard under boost. This is why a standalone is a VERY good idea.
High compression is better than running lower compression just because you want more boost. Who cares about boost? care about the power.


like I said. it all just depends on what he is trying to do.this is why so few people post is because of people like you wanting to start smarting off on some b.s.
Dude, you were saying that the N/A block can't handle boost aswell as the T11 donk? That is plain wrong.

9.7:1 rotors, 540hp and 25psi
'nuff said.

I said other people on here have done it and it works for them.
Just like you just did, I was simply stating my opinion on the matter.

Hmm.....

720 primary, 1600 secondary (the 1600s are cheap at any Ford dealer). And of course, a standalone ECU (ie. Microtech, Haltec, etc.) to control it all.


Should he get a Nippondenso or Walbro fuel pump??
Walbro. Cheap, works fine.


And could he control this whole system with a s-afc II. Please reply quickly cause we are trying to get this project started A.S.A.P.
He could, for about 1/4 mile. And then even a car with an S-AFC will have a hard time starting with 0 compression. With mods like this, a standalone is the only way to go ASSUMING you know how to tune it or can find someone who does.

Wankel7 01-07-05 05:25 PM

1600CC are cheap at any Ford deal? Okie, I am under a rock!

Do tell:)

James

StinkyTurbo 01-10-05 12:31 AM

like how cheap??

Wankel7 01-10-05 03:42 AM

144 for 2 1600CC I would say that is cheap. RX7store sells them for 100 a piece. Seems like you might have to cut off some plastic from teh top of the injector though at the fiveomotorsports injectors.
