Ok guys, so my Acura/Honda loving friend keeps trying to tell me that the top part of the 13BT that says "With Intercooler" is actually the intake manifold or a part of it. I think it's just a small intercooler, but I'm not 100% sure if it is or not. So who's right?




Also one of the reasons I ask is I'm trying to do a 88'-91' 13BT swap into a 87' GXL. And was wondering how I can get around 300HP with just some bolt ons, including an intercooler and/or slightly larger turbo. What are your opinions?

the intake manifold is the part that the intercooler is sitting/bolted on.

I could just remove that and get an after market intercooler, without having to get a an after market intake manifold also right?

yea.

4 bolts and 2 hose clamps, the TMIC is off.

the tmic can still support around 320 - 340 rwhp with a hi-flow stock turbo and fuel system upgarde + aftermarket ecu

you sure about that? ive heard that the tmic leaks around 10 psi. which doesnt seem anywhere near 320-340 with a "hi-flow stock turbo" (think bnr) which, brings up the next point, a decent bnr almost mandates the need for an upgraded intercooler. i think your information is slightly streched.

Just because you can doesn't make it less of a dumb idea. It would be a very inefficient set-up, using lots of boost to overcome the restriction and lots of fuel to prevent detonation due to the high intake temps caused by the high boost and inefficient intercooler. With a bigger/better IC you could make more power with less boost and less fuel.

You really think an intercooler is going to leak at 10psi? It's made of aluminium, not paper...

Over ~10psi the stock intercooler isn't really sufficient for the high intake temps generated by the stock turbo. With an upgraded turbo, the air temp may be lower for the same boost, but the flow is higher, and the stock intercooler will become restrictive. They're only 40-50mm pipes remember.

no **** bout the power figures, 240 -250kw at the wheels is possible with the stock tmic, it mightnt be the most efficient way to make that power but with other mods it can be made more so, ie water spray injection, plus there is less attention from the local constabulary. personaly im looking v mount setups to avoid the extra attention,lol

you dont need a larger turbo, FMIC, exhaust, standalone (or at least s-afc), you could get your desired power from your car if you cut some fat off it, and hacked the TMIC and built some end tanks for a re- mount, id look a bit ghetto.... but work, port your own turbo. dont forget injectors

dont listen to your honda buddies.

tell your honda buddies that you can wax that *** all day long with intake, exhaust, 720 secondary injectors, and SAFC. That's around 220-230rwhp usually and mid 13's with over 100mph trap on street tires. That's with $1000 or less in mods if you get good deals and you have a healthy motor. that usually takes a significant turbo build or a low weight all motor setup on a civic or integra.

talk about bad I/C's.. why waste your time with a v-mount if the "extra attention" is what you dont want. i have a MASSIVE front mount thats painted flat black and you cant even tell its there. but the blow off valve kinda gives my secret away....
a v mount is just going to soak up heat and, unless you do some major duct working, is just going to get the left over air from the rad. jk;'

And what is the lesson we learned today here class...?

Don't listen to Honda owners.

Well I'm thinking of doing the swap haven't done it yet, I'm running a stock 87' 13B right now but when I do the swap I'm prolly going to upgrade the turbo, intake manifold, and a front mount intercooler. I was wondering what some easy bolt on gains would be. I heard exhaust in this thread so far which I'm thinking of doing also although I'm going to try to get a non fart can dual set up.

Something I've been hearing a lot about is Porting specifically bridgeport's... I have no idea what the hell a bridgeport is a barley understand porting.

Just do a search on porting. There are bridge ports, half bridge ports, peripheral ports, street ports, and individual application variations of all those, since technically no port job is exactly the same for these motors.

Exhaust is basically the first thing to do because the stock system is so restrictive that you can hardly see any power gains if you don't do the exhaust.

dont port a motor unless your rebuilding it, a Bridgeport will be way less reliable than a mild street port or stock ports.....keep that in mind

maybe to you. myself and a few of my friends have been reliably running half and full bridged motors for 2 years of constant abuse of DD and some mild drifting and many acts of vehicular lunacy. reliability is in the tune and the builder.


best bang for buck turbo IMHO is the bnr stage 2 or 3.

there is no need for an aftermarket intake manifold as none exist that flows as well as stock and most are one-off custom pieces made from a fabricator.

the best exhaust you can put on your TII is the full racing beat if you can afford it. and for a cheap mod, send the turbo out to get the wastegate ported so you wont get boost creep when running higher boost with a free'd up exhuast.

just get exhaust, FMIC, 680cc injectors off of a GSL-SE RX-7 (first gen), and an SAFC and get it dyno tuned. you'll easily break 210hp.

and for god sakes dont overboost the turbo. i have blown 3 S5 turbos running a constant 16psi after a few months. given they were used units, im sure a rebuilt one wouldnt last more than a year

just basic mods to your TII and you'll be busting your honda boys' asses to them. even a boosted one shouldnt be a problem if they run less than 10psi on one of those kits.

^ you seemed to miss the point

******* USELESS TO PORT A MOTOR UNLESS YOU ARE REBUILDING IT

op, where in pa are u? if ur nearby i'll help u set those honda guys straight

no you missed it..... i meant about reliability.

everyone else stated "port it if you build it" "dont port unless you're building the motor" etc.....

this is not about to turn into a porting v.s. reliability thread.......... there has been enough of those..... the dispute never ends.
