Silvertop boost handling ability

[dnalunchie]

Out of curiosity how much boost do you guys reckon a stock silvertop could support assuming the proper fueling and a well tuned aftermarket ECU.

I was thinking like 6-10psi?

Also do you think a GT28 turbo would be too big for it or just right if the aim is good low down spool.

IF not the gt28 then which turbo would you recommend and why?

Just doing a bit of research for future projects very very far down the field.

P.S I know the topic has been discussed before but from what I found not the info on boost level specifics and turbo choice.

The silvia turbos or the td04 would be good sized for response etc

and assuming there is no knock it should be all good

Silvia uses GT28 I believe.

Depends which silvia

The earlier ones uses a T25

Depends what power you want

The s15 uses a T28 off the top of my head and is good for about 180kw I did lots of research into it ages ago ill see if I can dig it out when I get home

There was a project on here a few years ago, I think he ran 6psi on a TD04, and made 130 odd kw. Stock internals, can't remember what fuelling he had. Ran a V5 Link I think.

[jacobrjett]

did you buy a 101?

Thats the bugger....seems my memory is slipping in my old age Was a really nice looking car in the flesh too

Early SR20DETs ran a T25G, the later ones ran the T28s. I'm sure either would be well suited to a 4AGE.

Although, you're going to spend thousands setting up a proper fuel system and well-tuned aftermarket ECU but then run an internally stock 20ish year old engine, probably with 200+kms on it? You'd at least want to rebuild it.. but then, you'd be silly not to throw in at least GZE pistons along the way.. what are you planning to do with it?

This is why I told you to buy a Corona or Corolla Wagon

Just a toy. This isnt going to happen in the next few months but I like knowing how things work ahead of time. Goals are good, they keep you motivated.

I know the STI will spank it but something inside me still loves the idea of a cheesy boyracer levin with a turbo whacked on. Just the kid in me I guess.

Hah, I know what you mean. For all the factory turbo cars I've owned, I still entertain thoughts of throwing a turbo kit on a D or B series vtec EG Civic.. have wanted to for years.. lol.

With the right fuel and tuning and assuming it is a decent engine to start with I'd say 10 to 14 psi.

Pretty sure Willie's MR2 ran a standard ST turbo before he had it as one on the engines in it.

[Lurkin]

if the cars free, and you have access/ fabricate yourself.. sure why not.

I faced this situation with the ae101 I previously had.

Frankly, for the time/effort/money it was worth putting in forged pistons.

but then, for the time/effort/money of the above, there were cheaper options for a more powerful car, that would likely be more reliable in the long run.

low boost/ high comp... should be fun!

you want itsuki's car lol or wataru's car

Yeah, for some reason me too even though FWD turbos annoy me a bit. The combination of VTEC + boost makes for a very fun power delivery.

What I would do.

New rings, berrings, oil pump. Use upgraded valve springs as stock ST ones collapse under long term boost useage. Custom intake manifold, turbo exhaust manifold.

Use E85 for fuel so uprgading the fuel system is a must and aftermarket ECU. When tuning, the E85 will take more timing both under boost and off it giving greater throttle responce and increased torque/power throughout the rev range.

Select turbo for peak boost between 4-7000rpm. While larger turbos will provide greater power, this would setup will be more user friendly.

I see no reason that 14psi cant be used with this setup safely for a long engine life.

I know someone who is running 16psi on a stock silvertop except for 2 head gaskets, I think he uses an early evo turbo. Oh it's in his race car so you know it beaten on.
